Overview
•High doses of B vitamins (100 mg each for B1, B2, B3, B5, B6) are water-soluble and generally safe, with excess excreted in urine; however, B6 at 100 mg may cause neuropathy with long-term use exceeding 6 months.
•Potential interactions with medications like levodopa (B6 reduces efficacy), anticonvulsants (folic acid interference), and metformin (B12 deficiency risk); consult doctor if on these drugs.
•Dosages align with safe upper limits for most B vitamins per NIH guidelines, but avoid exceeding recommended intake without medical advice.
•Not suitable for pregnancy without physician approval due to high folic acid (400 mcg is RDA but total intake monitoring needed) and potential B6 risks.
•No major allergens in formulation, but gelatin capsules are animal-derived, unsuitable for vegans or those with bovine sensitivities.
•Low risk of contamination if manufactured under GMP standards, as typical for Nature's Blend products.
