Below is general information about the safety of the known ingredients contained in the product Fruit Fortress. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally and appropriately in amounts commonly found in foods. Bilberry has Generally Recognized As Safe status (GRAS) for use in foods in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately for medicinal purposes. Bilberry fruit extracts have been used with apparent safety in clinical trials at a dose of up to 160 mg daily for up to 6 months (39,40,8139,9739,14280,35472,35510,35512,103190,104192,104195). A higher bilberry extract dose of 1.4 grams daily has been used with apparent safety for up to 4 weeks (104194). Whole bilberries or bilberry juice have also been consumed with apparent safety in quantities of 100-160 grams daily for up to 35 days (35463,91506).
POSSIBLY UNSAFE ...when the leaves are used orally in high doses or for a prolonged period. Death can occur with chronic use of 1.5 gram/kg daily (2).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in the amounts commonly found in foods.
However, there is insufficient reliable information available about the safety of bilberry when used in medicinal amounts during pregnancy and lactation; avoid using.
LIKELY SAFE ...when the fruit is used orally in amounts commonly found in foods (4912). There is insufficient reliable information available about the safety of blackberry fruit or leaf when used in medicinal amounts.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using in amounts greater than those found in foods.
LIKELY SAFE ...when used orally and appropriately, short-term. Eleuthero root extract 300-2000 mg has been used safely in clinical trials lasting up to 3 months (730,1427,2574,7522,11099,15586,91509). There is insufficient reliable information available about the safety of eleuthero when used long-term.
CHILDREN: POSSIBLY SAFE
when used orally in adolescents aged 12-17 years, short-term.
Eleuthero 750 mg three times daily was used for 6 weeks with apparent safety in one clinical trial (75028). There is insufficient reliable information available about the safety of eleuthero in children or adolescents when used long-term.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used in amounts commonly found in foods. Lemon has Generally Recognized as Safe (GRAS) status in the US (4912).
POSSIBLY SAFE ...when inhaled in amounts used for aromatherapy, short-term. Lemon essential oil has been used with apparent safety as aromatherapy for up to 2 weeks in clinical research (93475,98128,98129). There is insufficient reliable information available about the safety of lemon when used topically, or when used orally or intranasally in medicinal amounts.

PREGNANCY: POSSIBLY SAFE
when red raspberry leaf is used orally and appropriately in medicinal amounts during late pregnancy under the supervision of a healthcare provider.
Red raspberry leaf is used by nurse midwives to facilitate delivery. There is some evidence that red raspberry leaf in doses of up to 2.4 grams daily, beginning at 32 weeks' gestation and continued until delivery, can be safely used for this purpose (6481,9796). Make sure patients do not use red raspberry leaf without the guidance of a healthcare professional.
PREGNANCY: LIKELY UNSAFE
when red raspberry leaf is used orally in medicinal amounts throughout pregnancy or for self-treatment.
Red raspberry leaf might have estrogenic effects (6180). These effects can adversely affect pregnancy. Tell pregnant patients not to use red raspberry leaf at any time during pregnancy without the close supervision of a healthcare provider.
LACTATION: LIKELY SAFE
when the fruit is used orally in amounts commonly found in foods (13622).
There is insufficient reliable information available about the safety of red raspberry leaf; avoid using.
Below is general information about the interactions of the known ingredients contained in the product Fruit Fortress. 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, bilberry fruit extract might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
 Details
|
Theoretically, bilberry leaf or fruit extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Details
Animal research suggests that bilberry leaf extract might have blood glucose-lowering activity (1264). Also, one small clinical trial in patients with type 2 diabetes shows that taking bilberry fruit extract 470 mg as a single dose prior to an oral glucose tolerance test lowers plasma glucose levels when compared with placebo (91507).
|
Theoretically, bilberry fruit extract might decrease levels of drugs metabolized by CYP2E1.
Details
Animal research shows that exposure to small concentrations of bilberry extract in drinking water for around one month increased CYP2E1 activity by 31%. However, exposure over a 2-month period did not increase CYP2E1 activity (103191). This effect has not been reported in humans.
|
Theoretically, bilberry fruit extract might reduce the efficacy of erlotinib.
Details
In vitro research suggests that bilberry fruit extract and its constituents, delphinidin and delphinidin-3-O-glucoside, inhibit the activity of erlotinib (97031). This interaction has not been reported in humans.
|
Theoretically, eleuthero may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, eleuthero might have additive effects when used with antidiabetes drugs.
Details
Animal research suggests that certain constituents of eleuthero have hypoglycemic activity in both healthy and diabetic animals (7591,73535,74932,74956,74988,74990). A small study in adults with type 2 diabetes also shows that taking eleuthero for 3 months can lower blood glucose levels (91509). However, one very small study in healthy individuals shows that taking powdered eleuthero 3 grams, 40 minutes prior to a 75-gram oral glucose tolerance test, significantly increases postprandial blood glucose levels when compared with placebo (12536). These contradictory findings might be due to patient-specific variability and variability in active ingredient ratios.
|
Theoretically, eleuthero might increase levels of drugs metabolized by CYP1A2.
Details
In vitro and animal research suggest that standardized extracts of eleuthero inhibit CYP1A2 (7532). This effect has not been reported in humans.
|
Theoretically, eleuthero might increase levels of drugs metabolized by CYP2C9.
Details
In vitro and animal research suggest that standardized extracts of eleuthero might inhibit CYP2C9 (7532). This effect has not been reported in humans.
|
Theoretically, eleuthero might increase levels of drugs metabolized by CYP2D6.
Details
|
Theoretically, eleuthero might increase levels of drugs metabolized by CYP3A4.
Details
|
Eleuthero might increase serum digoxin levels and increase the risk of side effects.
Details
In one case report, a 74-year-old male who was stabilized on digoxin presented with an elevated serum digoxin level after starting an eleuthero supplement, without symptoms of toxicity. After stopping the supplement, serum digoxin levels returned to normal (543). It is not clear whether this was due to a pharmacokinetic interaction or to interference with the digoxin assay (15585). Although the product was found to be free of digoxin and digitoxin (543), it was not tested for other contaminants (797).
|
Theoretically, eleuthero might interfere with immunosuppressive drugs because of its immunostimulant activity.
Details
|
Theoretically, eleuthero might decrease levels of drugs metabolized by OATP.
Details
In vitro research suggests that eleuthero inhibits OATP2B1, which might reduce the bioavailability of oral drugs that are substrates of OATP2B1 (35450). Due to the weak inhibitory effect identified in this study, this interaction is not likely to be clinically significant.
|
Theoretically, eleuthero might increase levels of P-glycoprotein substrates.
Details
|
Theoretically, taking itraconazole capsules or tablets with a beverage containing lemon might increase the levels and clinical effects of itraconazole.
Details
In one case report, dissolving itraconazole tablets in a small amount of specific beverages containing lemon prior to administration increased the level of itraconazole in a lung transplant patient. In this case, the increased bioavailability was desirable and was likely due to improved tablet dissolution in the acidic beverage (110781).
|
Theoretically, taking red raspberry leaf with anticoagulant/antiplatelet drugs might increase the risk of bleeding.
Details
In vitro research suggests that red raspberry leaf extract has antiplatelet activity and enhances the in vitro effects of the antiplatelet medication cangrelor (96300). This interaction has not been reported in humans.
|
Red raspberry leaf might reduce glucose levels in patients being treated with insulin.
Details
In one case report, a 38-year-old patient with gestational diabetes, whose blood glucose was being controlled with medical nutrition therapy and insulin, developed hypoglycemia after consuming two servings of raspberry leaf tea daily for 3 days beginning at 32 weeks' gestation. The patient required an insulin dose reduction. The hypoglycemia was considered to be probably related to use of red raspberry leaf tea (96299).

Below is general information about the adverse effects of the known ingredients contained in the product Fruit Fortress. 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, bilberry fruit, juice, and extracts seem to be well tolerated.
Most Common Adverse Effects:
Orally: Dark-colored stools, flatulence, and gastrointestinal discomfort.
Gastrointestinal
...In one small clinical trial, mild-to-moderate flatulence was reported in 33% of patients taking sieved bilberries and concentrated bilberry juice (91506).
However, the patients in this study had ulcerative colitis, and the study lacked a control group, limiting the validity of this finding. In another small clinical study of males with age-related cognitive impairment, temporary adverse gastrointestinal (GI) effects were reported in 13% of patients drinking a combination of bilberry and grape juice. However, the adverse GI effect rate was identical in patients drinking a placebo juice (110641). A post-marketing surveillance report of 2295 patients using bilberry extract (Tegens) found that 1% of patients complained of GI discomfort and less than 1% experienced nausea or heartburn (35500).
Theoretically, fresh bilberry fruit may have laxative effects. One clinical trial noted an increased frequency of bowel movements following the administration of a combination formulation containing aerial agrimony parts, cinnamon quills, powdered bilberry fruit, and slippery elm bark (35462). It is unclear if these effects were due to bilberry, other ingredients, or the combination.
Other ...Orally, bilberry may cause discoloration of feces and the tongue. In one study, a dark-bluish to black discoloration of both the feces and the tongue was observed following consumption of sieved bilberries and concentrated bilberry juice. In one patient, a slight discoloration of the teeth has also been observed (91506). In another study, 50% of patients reported dark green stools after taking bilberry extract 700 mg twice daily for 4 weeks (104194).
General ...Blackberry fruit is commonly consumed as a food without reports of adverse effects. However, a thorough evaluation of safety outcomes for blackberry when used as a medicine has not been conducted.
General
...Orally, eleuthero root is generally well tolerated when used short-term.
Most Common Adverse Effects:
Orally: Diarrhea, dyspepsia, gastrointestinal upset, headache, nausea, and urticaria.
Cardiovascular ...Orally, increased blood pressure has been reported in children with hypotension taking eleuthero in one clinical study (74980). Eleuthero has been reported to cause tachycardia, hypertension, and pericardial pain in patients with rheumatic heart disease or atherosclerosis. It is unclear if these effects were caused by eleuthero, or by the cardioglycoside-containing herb, silk vine (Periploca sepium), which is a common adulterant found in eleuthero products (12,797,6500).
Dermatologic ...Orally, eleuthero has been reported to cause rash in some clinical studies (75013,75028).
Gastrointestinal ...Orally, eleuthero has been reported to cause dyspepsia, nausea, diarrhea, and gastrointestinal upset in some patients (74938,75028,91510).
Genitourinary ...Orally, mastalgia and uterine bleeding were reported in 7. 3% of females taking eleuthero 2 grams daily in one clinical study (6500,11099). These adverse effects seem to be more likely with higher doses.
Neurologic/CNS
...Orally, headaches have been reported in 9.
8% of people taking eleuthero in one clinical study (11099).
In one case report, a 53-year-old female developed spontaneous subarachnoid hemorrhage associated with the use of an herbal supplement containing red clover, dong quai, and eleuthero (70419). It is unclear if this event was related to the use of eleuthero, the other ingredients, the combination, or another cause entirely.
Psychiatric ...Orally, nervousness has been reported in 7. 3% of people taking eleuthero in one clinical study (11099). Eleuthero has also been reported to cause slight anxiety, irritability, and melancholy in some patients (6500,11099). These adverse effects seem to be more likely to occur with higher doses.
General
...Orally, lemon is well tolerated in amounts commonly found in foods.
A thorough evaluation of safety outcomes has not been conducted on the use of larger amounts.
Most Common Adverse Effects:
Orally: Epigastralgia and heartburn with the regular consumption of fresh lemon juice.
Dermatologic ...Topically, the application of lemon oil might cause photosensitivity, due to furocoumarin derivative content. This occurs most often in fair-skinned people (11019).
Gastrointestinal ...Orally, fresh lemon juice, taken as 60 mL twice daily, has been reported to cause gastrointestinal disturbances in 37% of patients in one clinical trial, compared with 8% of patients in the placebo group. Specifically, of the patients consuming lemon juice, 21% experienced heartburn and 8% experienced epigastralgia, compared to 1% and 3%, respectively, in the placebo group (107489).
General
...Orally, red raspberry fruit is well tolerated.
There is currently a limited amount of information on the adverse effects of red raspberry leaf.
Most Common Adverse Effects:
Orally: Diarrhea, gastrointestinal upset, and epigastric pain. However, these adverse effects do not commonly occur with typical doses.
Dermatologic ...A liquid containing red raspberry leaf cell culture extract 0. 0005%, vitamin C 20%, and vitamin E 1% (Antioxidant and Collagen Booster Serum, Max Biocare Pty Ltd.) has been reported to cause mild tingling and skin tightness (102355). It is unclear if these effects are due to red raspberry leaf, the other ingredients, or the combination.
Gastrointestinal ...Orally, red raspberry may cause gastrointestinal upset, diarrhea, and epigastric pain (112127).
Pulmonary/Respiratory ...A case of occupational asthma due to the inhalation of red raspberry powder has been reported for a 35-year-old female. Symptoms included wheezing and shortness of breath (70370).
