Nutricost Vitamin B6 100 mg
Brand: Nutricost · Form: CAPSULE [E0159] On Market
Our assessment
Our assessment: Nutricost Vitamin B6 100 mg is a high-dose supplement. The evidence shows that vitamin B6 is essential for over 100 enzyme reactions in the body, primarily related to protein metabolism and red blood cell formation [NIH ODS]. However, data on this specific product is limited, and we must rely on general ingredient information.
How it works
Vitamin B6, also known as pyridoxine, acts as a coenzyme critical for amino acid metabolism, neurotransmitter synthesis, and immune function [NIH ODS]. The 100 mg dose in this product is significantly higher than the Recommended Dietary Allowance (RDA) for adults, which is about 1.3 to 1.7 mg daily [NIH ODS]. This high dose is sometimes used under medical supervision for specific conditions, but is not intended for general daily use without a clear need.
Safety profile
Safety profile: For vitamin B6 specifically, the FDA has received a total of 592,059 adverse event reports across all supplements, but data for this specific product is not available. High doses of vitamin B6 (typically over 100 mg daily) taken for long periods can cause nerve toxicity, leading to numbness and difficulty walking [NIH ODS]. Because this product provides 100 mg per serving, long-term use without medical oversight carries this risk. Data not available for specific side effects reported for this exact brand.
Our recommendation
Our recommendation: We do not recommend taking 100 mg of vitamin B6 daily without a specific medical reason and oversight. For most people, a standard multivitamin or a lower-dose B-complex (containing 1.5–2 mg of B6) meets your needs [NIH ODS]. If you are considering this product, consult with your healthcare provider to check your B6 levels and discuss the potential for nerve-related side effects. Start with a lower dose to assess your tolerance and need [NIH ODS].
