Natural Factors Vitamin B6 250 mg

Our assessment
The evidence shows that this product contains 250 mg of vitamin B6, which is far above the recommended daily intake. Our assessment: this is a high-dose formulation that should only be used under specific medical supervision, as the data on this specific product is limited to its label information. Data not available for how this specific dose impacts bone mineralization or neuromuscular relaxation, as those effects are associated with calcium, not vitamin B6 [NIH ODS].

Think of vitamin B6 as a cofactor for over 100 enzymes involved in metabolism. However, the specific mechanisms for this 250 mg dose are not detailed in the data provided. The data provided describes calcium's role in bone mineralization and neuromuscular relaxation, which is not applicable here [NIH ODS]. For vitamin B6, specific mechanisms at this high dose are not available in the provided data.
Safety profile
FDA has received a total of 592,059 adverse event reports across all supplements, but the data does not specify how many are tied directly to this product or vitamin B6 at 250 mg. Side effects for high-dose vitamin B6 are not listed in the provided FDA data or NIH ODS section, so side effects and report counts are not available. Data not available for specific adverse events or report counts for this product [FDA data].
Our recommendation
Our recommendation: do not take this product without consulting a physician. The 250 mg dose is extremely high, and the data provided does not support safe self-administration. Data not available on interactions, safety, or efficacy for this specific dose. Choose a standard multivitamin or lower-dose B6 supplement instead, as the evidence for high-dose B6 is not present in the provided data [NIH ODS] [FDA data].
