Below is general information about the safety of the known ingredients contained in the product Vegan Protein Unflavored. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
POSSIBLY SAFE ...when non-contaminated species of spirulina blue-green algae are used orally and appropriately (91713). The blue-green algae species Arthrospira platensis has been used with apparent safety in doses up to 19 grams daily for 2 months, or 10 grams daily for 6 months (18296,18300,18306,75944,91705,99703,104567,109965). The blue-green algae species Arthrospira fusiformis has been used with apparent safety in doses up to 4 grams daily for 3 months, or 1 gram daily for 12 months (15782,91717). Another blue-green algae species, Arthrospira maxima, has been used with apparent safety in a dose of 4.5 grams daily for up to 12 weeks (18297,99654,99655,102688). ...when non-contaminated, non-toxin producing strains of blue-green algae from the Aphanizomenon flos-aquae species are used orally and appropriately. Doses up to 1.6 grams daily have been used with apparent safety for up to 6 months (14842,18310). Some blue-green algae species can produce toxins called microcystins. According to the World Health Organization (WHO), the tolerable daily intake of microcystins in adults is 0.04 mcg/kg (96549).
POSSIBLY UNSAFE ...when contaminated blue-green algae are used orally. Blue-green algae can be contaminated with heavy metals (including mercury, cadmium, lead, or arsenic), neurotoxins, and toxic microcystin-producing cyanobacteria such as Microcystis aeruginosa (9171,75966,91704,91711,96550). Microcystins are most commonly reported in the blue-green algae species Aphanizomenon flos-aquae harvested from Upper Klamath Lake in Oregon. The Oregon Department of Health has set a limit of 1 mcg of microcystin-LR equivalents per gram dry weight of blue-green algae, assuming consumption of about 2 grams/day by adults (91704,91713). However, many samples of Aphanizomenon flos-aquae have been reported to contain higher levels than this (9171,91704). According to the World Health Organization (WHO), the tolerable daily intake of microcystins in adults is 0.04 mcg/kg (96549). When consumed orally, microcystins accumulate in the liver, binding to and inhibiting protein phosphatases, causing hepatocyte damage and possible tumor promotion (9171). Aphanizomenon flos-aquae can also produce neurotoxic compounds that may be present in supplements containing this organism (91704).
CHILDREN: POSSIBLY UNSAFE
when blue-green algae products are used orally.
Blue-green algae can accumulate heavy metals such as lead and mercury (91704,91711). They can also contain toxic microcystins produced by contaminating species of cyanobacteria such a Microcystis aeruginosa (91704). Children are more sensitive to poisoning by microcystins (3536). The Oregon Department of Health has set a limit for microcystins of 1 mcg per gram dry weight of blue-green algae, but some countries have set very low exposure limits of 0.2 mcg per day and 0.8 mcg per day for infants and children, respectively (91704).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
Some blue-green algae products, specifically those of the species Aphanizomenon flos-aquae, have been found to contain low amounts of beta-methylamino-L-alanine (BMAA). BMAA is associated with neurodegenerative diseases, and breast milk has been shown to be a potential source of BMAA exposure in infants (96550).
LIKELY SAFE ...when used orally in amounts commonly found in foods (104531,104532).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts, short-term. Chia has been used safely at doses up to 40 grams daily for up to 6 months (16124,97940). ...when used topically, short-term. A product containing chia seed oil 4% has been applied to the skin safely for up to 8 weeks (25537).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally and appropriately, short-term. Tablets and liquids containing chlorella 3-10 grams or 60-100 mL daily have been safely used in clinical studies lasting 2-3 months (5890,92130,92131). Also, chlorella extract 200-1800 mg daily has been safely used in clinical research for 4-6 weeks (10388,92132). There is insufficient reliable information available about the safety of chlorella when used topically.
PREGNANCY: POSSIBLY SAFE
when used orally and appropriately in medicinal amounts for up to approximately 28 weeks.
A commercially available chlorella supplement (Sun Chlorella A, Sun Chlorella Corp.) has been safely used in doses of 6 grams daily, starting during the 12-18th week of gestation and continuing until delivery (95013).
LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally in food amounts. Pea protein is commonly consumed as a food (94935,94970,94981).
POSSIBLY SAFE ...when pea protein is used orally in medicinal amounts, short term. Pea protein has been used with apparent safety in doses of up to 50 grams daily for up to 12 weeks (95426,94934,102013,104758,104759). ...when pea protein hydrolysate is used orally, short term. A pea protein hydrolysate has been used with apparent safety at doses of up to 3 grams daily for up to 3 weeks (94973).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using in amounts greater than those found in food.
LIKELY SAFE ...when used orally and appropriately in amounts commonly found in foods.
POSSIBLY SAFE ...when the seed or seed oil is used orally and appropriately in medicinal amounts, short-term. Pumpkin seed has been used with apparent safety in a dose of up to 10 grams daily for up to 12 months (92383). Pumpkin seed oil has been used with apparent safety in a dose of up to 400 mg daily for up to 6 months (92378). There is insufficient reliable information available about the safety of pumpkin seed oil when used topically.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using amounts greater than those found in food.
LIKELY SAFE ...when used orally and appropriately. Sodium is safe in amounts that do not exceed the Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams daily (100310). Higher doses can be safely used therapeutically with appropriate medical monitoring (26226,26227).
POSSIBLY UNSAFE ...when used orally in high doses. Tell patients to avoid exceeding the CDRR intake level of 2.3 grams daily (100310). Higher intake can cause hypertension and increase the risk of cardiovascular disease (26229,98176,98177,98178,98181,98183,98184,100310,109395,109396,109398,109399). There is insufficient reliable information available about the safety of sodium when used topically.
CHILDREN: LIKELY SAFE
when used orally and appropriately (26229,100310).
Sodium is safe in amounts that do not exceed the CDRR intake level of 1.2 grams daily for children 1 to 3 years, 1.5 grams daily for children 4 to 8 years, 1.8 grams daily for children 9 to 13 years, and 2.3 grams daily for adolescents (100310).
CHILDREN: POSSIBLY UNSAFE
when used orally in high doses.
Tell patients to avoid prolonged use of doses exceeding the CDRR intake level of 1.2 grams daily for children 1 to 3 years, 1.5 grams daily for children 4 to 8 years, 1.8 grams daily for children 9 to 13 years, and 2.3 grams daily for adolescents (100310). Higher intake can cause hypertension (26229).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Sodium is safe in amounts that do not exceed the CDRR intake level of 2.3 grams daily (100310).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in higher doses.
Higher intake can cause hypertension (100310). Also, both the highest and the lowest pre-pregnancy sodium quintile intakes are associated with an increased risk of hypertensive disorders of pregnancy, including gestational hypertension and pre-eclampsia, and the delivery of small for gestational age (SGA) infants when compared to the middle intake quintile (106264).
Below is general information about the interactions of the known ingredients contained in the product Vegan Protein Unflavored. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, spirulina blue-green algae might increase the risk of bleeding if used with other anticoagulant or antiplatelet drugs. However, this is unlikely.
Details
Spirulina blue-green algae have shown antiplatelet and anticoagulant effects in vitro (18311,18312,75892,92162,92163). However, one preliminary study in 24 patients receiving spirulina blue-green algae 2.3 grams daily for 2 weeks showed no effect on platelet activation or measures of clotting time (97202).
|
Theoretically, taking blue-green algae with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Human research shows that spirulina blue-green algae can have hypoglycemic effects in patients with diabetes, at least some of whom were using antidiabetes drugs (18299). However, blue-green algae does not seem to improve glycated hemoglobin (HbA1c) levels in patients with diabetes (102689,109970). A meta-analysis of animal studies also suggests that spirulina blue-green algae have hypoglycemic effects (109970).
|
Theoretically, concurrent use of blue-green algae might interfere with immunosuppressive therapy.
Details
|
Theoretically, chlorella might have additive effects with photosensitizing drugs.
Details
Chlorella has been reported to cause photosensitization (3900,5852). In five case reports, patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body (5852). Theoretically, concomitant use with photosensitizing drugs may exacerbate effects.
|
Theoretically, chlorella might reduce the clinical effects of warfarin.
Details
|
Pumpkin might reduce excretion and increase levels of lithium.
Details
Pumpkin is thought to have diuretic properties (92383). Theoretically, this might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.
|
Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
Details
|
Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Details
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone (4425).
|
Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
Details
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion (26225). Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate (26224,26225). Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L (112909). Patients taking lithium should avoid significant alterations in their dietary intake of sodium.
|
Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
Details
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population (100310). Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.
|
Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Details
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia (29406). Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.

Below is general information about the adverse effects of the known ingredients contained in the product Vegan Protein Unflavored. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, spirulina blue-green algae seem to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal cramps, bloating, diarrhea, dizziness, fatigue, flatulence, headache, nausea, and vomiting.
Dermatologic ...Orally, a severe rash has been reported in a 49-year-old woman after taking a spirulina blue-green algae supplement (species and dose unknown). After stopping the supplement, inflammatory myopathy with muscle weakness and elevated creatine kinase occurred. The condition resolved with corticosteroid and cyclophosphamide treatment (75936). In another case report, an 82 year-old woman developed a blistering skin condition over a 2-year period while taking spirulina blue-green algae (A. platensis, dose unknown). She had partly hemorrhagic bullae, secreting erosions and macerations. These symptoms resolved when the supplement was stopped and the patient was treated with oral prednisone, topical silver sulfadiazine, and topical triamcinolone / neomycin (75921).
Gastrointestinal ...Orally, gastrointestinal complaints are amongst the most common adverse effects associated with spirulina blue-green algae, including nausea, vomiting, diarrhea, and abdominal cramps (19272,75924,91713,109969). Similarly, common adverse effects associated with the blue-green algae species Aphanizomenon flos-aquae are stomach upset, flatulence, diarrhea, and bloating (14842).
Hematologic ...Orally, three cases of mild gum bleeding and one case of mild bruising have been reported in patients taking spirulina blue-green algae (Cyactiv, Cerule LLC) 2. 3 grams daily (containing approximately 1 gram of phycocanin) for 2 weeks (97202).
Hepatic ...Orally, significant elevations of liver function tests within 2 weeks of starting a spirulina blue-green algae supplement (species and dose unknown) have been reported in a 52-year-old man stabilized on amlodipine, simvastatin, and acarbose. A biopsy showed feathery degeneration and ballooning of hepatic cells. Cholestasis was present, and an ex-vivo lymphocyte stimulation test for spirulina blue-green algae was positive. All drugs and the spirulina blue-green algae supplement were stopped, with return of the LFTs to normal (9172).
Immunologic
...Orally, urticarial rashes and pruritus have occurred as part of generalized allergic reactions to blue-green algae (91706,91711,91712).
In one case report, a 14-year-old male experienced anaphylaxis with urticaria, lip edema, and asthma 6 hours after taking five tablets of spirulina blue-green algae (A. platensis, strength unknown). He had a positive skin prick test. Oral challenge to an extract of the tablets, and IgE from his serum, reacted with the beta chain of C-phycocyanin from A. platensis (91712).
In another case report, a 17-year-old male with a history of multiple allergies developed rash, pruritus, angioedema, wheezing, and dyspnea within 10 minutes of taking spirulina blue-green algae (A. platensis) 300 mg. He had a positive skin test to A. platensis but no other ingredients of the tablets (91706).
Musculoskeletal ...Orally, after a 49-year-old woman stopped taking a spirulina blue-green algae supplement (species and dose unknown), the patient experienced inflammatory myopathy with muscle weakness and elevated creatine kinase. The condition resolved with corticosteroid and cyclophosphamide treatment (75936). Another case report describes acute rhabdomyolysis that occurred after consumption of spirulina (Arthrospira platensis, Hawaiian spirulina, Solgar Inc., Leonia, NJ) 3 grams daily for 1 month. The 24-year old man presented with weakness, myalgias, elevated creatine kinase and liver function tests, and myoglobinuria (75922).
General
...Orally and topically, chia seems to be well tolerated.
Most Common Adverse Effects:
Orally: Flatulence and soft stools.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis in sensitive individuals.
Cardiovascular ...Chia contains a high concentration of alpha-linolenic acid (ALA). There is some concern that ALA might increase triglyceride levels more than other omega-3 fatty acids (12918); however, clinical research with a specific variety of chia called Salba shows that it does not significantly increase triglyceride levels (16124).
Gastrointestinal ...Orally, chia might cause mild gastrointestinal adverse effects. Some patients consuming chia 40 grams daily for up to 6 months reported mild and transient gastrointestinal adverse effects such as flatulence and soft stools; however, the frequency of these adverse effects was similar to patients consuming an oat bran control (97940). Bloating and flatulence have been reported with a chia flour-based sports beverage (112385).
Immunologic ...Orally, chia might cause anaphylaxis in sensitive individuals. A single case of IgE-mediated anaphylactic reaction has been reported for a patient who consumed chia seeds. Symptoms, including pruritus in the mouth, urticaria, facial angioedema, shortness of breath, and dizziness, developed a few days after consuming chia seeds. The reaction was attributed to sensitivity to proteins in chia seeds (91517).
Oncologic ...Chia seeds contain a high concentration of alpha-linolenic acid (ALA). Epidemiologic research suggests that high dietary intake of ALA might increase risk for prostate cancer (1337,2558,7823,7147,12978). Other research suggests high intake or serum levels of ALA does not increase the overall risk of prostate cancer (12961,15736); however, it might increase the risk of advanced prostate cancer (12961). Association with prostate cancer appears to depend on the sources of ALA. Dairy and meat sources have been positively associated with prostate cancer, whereas plant sources, such as chia seed, don't seem to affect prostate cancer risk (12909). According to a clinical trial, intake of ALA does not appear to increase levels of prostate specific antigen (PSA) (91402).
General
...Orally, chlorella is generally well-tolerated.
Most Common Adverse Effects:
Orally: Allergic reactions, abdominal cramping, constipation, diarrhea, fatigue, flatus, nausea, photosensitivity, and stool discoloration.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis.
Dermatologic ...Orally, photosensitivity reactions have occurred following ingestion of chlorella (3900,5852). According to case reports, five patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body (5852). The photosensitizing agent in the chlorella tablets was identified as pheophorbide-a and its ester.
Gastrointestinal
...Orally, chlorella can cause diarrhea, abdominal cramping, flatus, and nausea, especially during the first two weeks of treatment (5890,6804,92130,92132).
In one clinical trial, one out of 42 patients reported nausea and one reported diarrhea (92132). In another trial, taking chlorella tablets (Sun Chlorella A, Sun Chlorella Corp) and a chlorella extract (Wakasa Gold, Sun Chlorella Corp) resulted in transient worsening of constipation in 4 of 13 patients and transient mild diarrhea in 2 of 13 patients (92130).
Green discoloration of the feces has also been reported, due to the chlorophyll content of chlorella (6804,95013).
Hematologic ...Orally, chlorella has been linked to one case of thrombocytopenia; however, causality has not been determined. A 49-year-old female living in Turkey presented with thrombocytopenia (a platelet count of 27,000/mm3) after taking chlorella 1080 mg daily for 20 days. Platelet counts had been normal one month earlier, and returned to normal two weeks after discontinuing the chlorella supplement (99879).
Immunologic ...Allergic reactions, including asthma and anaphylaxis, have been reported in people taking chlorella and in those preparing chlorella tablets (3900,5847,41827,105645).
Neurologic/CNS
...Orally, manganese (Mn)-induced parkinsonism has been reported after long-term consumption of chlorella extract.
In this case, a patient on maintenance hemodialysis reported gait disturbance, dysarthria, elevated serum and cerebrospinal fluid manganese levels, and abnormal magnetic resonance imaging (MRI) findings of the brain. The authors identified the condition as a rare case of Mn-induced parkinsonism, which may have been due to long-term ingestion of a chlorella extract containing 1.7 mg of Mn in the usual daily dose. The patient underwent edetic acid infusion therapy, which improved the MRI abnormalities and the other symptoms improved four months later (41817).
In one study, fatigue was reported in 18 of 41 patients receiving chlorella 200 mg (10388).
General
...Orally, pea protein seems to be well tolerated.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis in sensitive individuals.
Immunologic ...Orally, pea protein may cause allergic reactions in individuals sensitive to other foods. A case series describes 6 children who had anaphylactic reactions to pea protein present in a number of food items. Other symptoms included angioedema, urticaria, and asthma. All the children had a history of allergies to other foods including peanuts, tree nuts, chickpeas, lentils, or kidney beans (102012).
General
...Orally, pumpkin products are generally well tolerated.
Most Common Adverse Effects:
Orally: Abdominal discomfort, diarrhea, nausea, and vomiting.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis.
Dermatologic ...There are two case reports of adult females developing substantial transient hair loss 1-3 weeks after consumption of a meal containing either bitter-tasting pumpkin or undefined squash. This adverse effect was attributed to a high concentration of cucurbitacin, which is commonly found in wild pumpkins (104535).
Gastrointestinal ...Orally, pumpkin seed oil has been reported to cause mild abdominal discomfort in clinical trials (5093,92378). There are also two case reports of adults developing severe nausea, vomiting, and diarrhea following consumption of a meal containing either bitter-tasting pumpkin or undefined squash. These adverse effects were attributed to a high concentration of cucurbitacin, which is commonly found in wild pumpkins (104535).
Immunologic
...Orally, pumpkin seed oil and pumpkin pulp have been reported to cause anaphylactic reactions in children and adults.
A case review highlights 4 cases of anaphylaxis in children (3 from pumpkin pulp, 1 from pumpkin seeds), and 7 cases in adults (1 from pumpkin flesh, 6 from pumpkin seeds). Symptoms of anaphylaxis include urticaria, angioedema of the lips or face, dyspnea, dysphagia, and oropharyngeal itching and swelling. A case report describes a 2-year-old male presenting with urticaria, swollen lips, and increased dyspnea 10 minutes after ingesting pumpkin seeds. The patient was found to have elevated allergen-specific immunoglobulin E (IgE) and a positive skin-prick test for pumpkin seeds. Symptoms resolved after treatment with epinephrine, systemic glucocorticoids, salbuterol, and antihistamines (107843).
There may also be concern for allergic reaction due to inhalation or topical exposure. One case report describes an 8-year-old child developing anaphylaxis while carving a pumpkin; another highlights that inhalation of pumpkin seed flour may have potentiated anaphylaxis in 3 individuals following the ingestion of pumpkin seeds (107843). Further research is necessary to assess the relationship between anaphylaxis and route of administration.
General
...Orally, sodium is well tolerated when used in moderation at intakes up to the Chronic Disease Risk Reduction (CDRR) intake level.
Topically, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Worsened cardiovascular disease, hypertension, kidney disease.
Cardiovascular
...Orally, intake of sodium above the CDRR intake level can exacerbate hypertension and hypertension-related cardiovascular disease (CVD) (26229,98176,100310,106263).
A meta-analysis of observational research has found a linear association between increased sodium intake and increased hypertension risk (109398). Observational research has also found an association between increased sodium salt intake and increased risk of CVD, mortality, and cardiovascular mortality (98177,98178,98181,98183,98184,109395,109396,109399). However, the existing research is unable to confirm a causal relationship between sodium intake and increased cardiovascular morbidity and mortality; high-quality, prospective research is needed to clarify this relationship (100312). As there is no known benefit with increased salt intake that would outweigh the potential increased risk of CVD, advise patients to limit salt intake to no more than the CDRR intake level (100310).
A reduction in sodium intake can lower systolic blood pressure by a small amount in most individuals, and diastolic blood pressure in patients with hypertension (100310,100311,106261). However, post hoc analysis of a small crossover clinical study in White patients suggests that 24-hour blood pressure variability is not affected by high-salt intake compared with low-salt intake (112910). Additionally, the available research is insufficient to confirm that a further reduction in sodium intake below the CDRR intake level will lower the risk for chronic disease (100310,100311). A meta-analysis of clinical research shows that reducing sodium intake increases levels of total cholesterol and triglycerides, but not low-density lipoprotein (LDL) cholesterol, by a small amount (106261).
It is unclear whether there are safety concerns when sodium is consumed in amounts lower than the adequate intake (AI) levels. Some observational research has found that the lowest levels of sodium intake might be associated with increased risk of death and cardiovascular events (98181,98183). However, this finding has been criticized because some of the studies used inaccurate measures of sodium intake, such as the Kawasaki formula (98177,98178,101259). Some observational research has found that sodium intake based on a single 24-hour urinary measurement is inversely correlated with all-cause mortality (106260). The National Academies Consensus Study Report states that there is insufficient evidence from observational studies to conclude that there are harmful effects from low sodium intake (100310).
Endocrine ...Orally, a meta-analysis of observational research has found that higher sodium intake is associated with an average increase in body mass index (BMI) of 1. 24 kg/m2 and an approximate 5 cm increase in waist circumference (98182). It has been hypothesized that the increase in BMI is related to an increased thirst, resulting in an increased intake of sugary beverages and/or consumption of foods that are high in salt and also high in fat and energy (98182). One large observational study has found that the highest sodium intake is not associated with overweight or obesity when compared to the lowest intake in adolescents aged 12-19 years when intake of energy and sugar-sweetened beverages are considered (106265). However, in children aged 6-11 years, usual sodium intake is positively associated with increased weight and central obesity independently of the intake of energy and/or sugar-sweetened beverages (106265).
Gastrointestinal ...In one case report, severe gastritis and a deep antral ulcer occurred in a patient who consumed 16 grams of sodium chloride in one sitting (25759). Chronic use of high to moderately high amounts of sodium chloride has been associated with an increased risk of gastric cancer (29405).
Musculoskeletal
...Observational research has found that low sodium levels can increase the risk for osteoporosis.
One study has found that low plasma sodium levels are associated with an increased risk for osteoporosis. Low levels, which are typically caused by certain disease states or chronic medications, are associated with a more than 2-fold increased odds for osteoporosis and bone fractures (101260).
Conversely, in healthy males on forced bed rest, a high intake of sodium chloride (7.7 mEq/kg daily) seems to exacerbate disuse-induced bone and muscle loss (25760,25761).
Oncologic ...Population research has found that high or moderately high intake of sodium chloride is associated with an increased risk of gastric cancer when compared with low sodium chloride intake (29405). Other population research in patients with gastric cancer has found that a high intake of sodium is associated with an approximate 65% increased risk of gastric cancer mortality when compared with a low intake. When zinc intake is taken into consideration, the increased risk of mortality only occurred in those with low zinc intake, but the risk was increased to approximately 2-fold in this sub-population (109400).
Pulmonary/Respiratory ...In patients with hypertension, population research has found that sodium excretion is modestly and positively associated with having moderate or severe obstructive sleep apnea. This association was not found in normotensive patients (106262).
Renal ...Increased sodium intake has been associated with impaired kidney function in healthy adults. This effect seems to be independent of blood pressure. Observational research has found that a high salt intake over approximately 5 years is associated with a 29% increased risk of developing impaired kidney function when compared with a lower salt intake. In this study, high salt intake was about 2-fold higher than low salt intake (101261).
