INSUFFICIENT RELIABLE EVIDENCE to RATE

• Allergic rhinitis (hay fever). It is unclear if oral fulvic acid is beneficial in patients with allergic rhinitis. Details: Preliminary clinical research in people with allergic rhinitis shows that taking fulvic acid solution 3.8%, 40 mL orally twice daily for 7 days, reduces the size of cutaneous wheals from pollen prick tests by about 1.5 mm when compared with baseline (90589). The validity of this finding is limited by the lack of a comparator group.
• Alzheimer disease. Although there has been interest in using oral fulvic acid for Alzheimer disease, there is insufficient reliable information about the clinical effects of fulvic acid for this purpose.
• Atopic dermatitis (eczema). It is unclear if topical fulvic acid is beneficial in patients with atopic dermatitis. Details: Preliminary clinical research in adults with eczema shows that applying fulvic acid 5% in an emollient base twice daily to affected areas for 4 weeks modestly improves eczema symptom scores when compared with placebo (90588).
• Cancer. Although there has been interest in using oral fulvic acid for cancer, there is insufficient reliable information about the clinical effects of fulvic acid for this purpose.
• Fatigue. Although there has been interest in using oral fulvic acid for fatigue, there is insufficient reliable information about the clinical effects of fulvic acid for this purpose.
• Lead toxicity. Although there has been interest in using oral fulvic acid for lead toxicity, there is insufficient reliable information about the clinical effects of fulvic acid for this purpose.
• Respiratory tract infections. Although there has been interest in using oral fulvic acid for respiratory tract infections, there is insufficient reliable information about the clinical effects of fulvic acid for this purpose. More evidence is needed to rate fulvic acid for these uses.

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, taking fulvic acid may decrease the effectiveness of anticoagulant and antiplatelet drugs.  Details In vitro evidence shows that fulvic acid, formed from the oxidation and polymerization of protocatechuic acid, can shorten prothrombin time in human plasma, increasing the risk of clot formation (27726).

IMMUNOSUPPRESSANTS Interaction Rating = Moderate Be cautious with this combination. Severity = High •  Occurrence = Possible •  Level of Evidence = D Theoretically, taking fulvic acid might decrease the effects of immunosuppressive therapy.  Details Animal research shows that fulvic acid stimulates immune function (27727).

THYROID HORMONE Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, taking fulvic acid with thyroid hormone therapy might interfere with the ability to normalize thyroid function.  Details Animal research shows that fulvic acid increases the plasma level of thyroid-stimulating hormone (TSH) and decreases the thyroxine (T4):triiodothyronine (T3) ratio (27727).

General ...Orally, fulvic acid appears to be well tolerated. Topically, adverse effects seem to be rare; however, a thorough safety evaluation has not been conducted.
Most Common Adverse Effects:
Orally: Diarrhea, headache, sore throat.
Serious Adverse Effects (Rare):
Orally: Kashin-Beck bone disease.

Gastrointestinal ...In one clinical trial, fulvic acid 3. 8% 40 mL taken orally twice daily resulted in diarrhea and sore throat in some patients (90589).

Musculoskeletal ...Although there is no evidence from well-conducted studies, there is concern that pollution of water with high concentrations of fulvic acids may contribute to the development of Kashin-Beck bone disease, particularly in areas in which selenium intake is insufficient (27722,27725,29971).

Neurologic/CNS ...In one clinical trial, fulvic acid 3. 8% 40 mL taken orally twice daily resulted in headache in some patients (90589).
