Natural Factors Pyridoxine HCl B6 250 mg
Brand: Natural Factors · Form: TABLET [E0155]
Our assessment
The evidence shows that this product contains 250 mg of vitamin B6 (pyridoxine HCl), which is a very high dose. The data for the ingredient calcium, not B6, is provided. Based on the available data for calcium, high intakes of minerals require careful monitoring. For your B6 supplement, specific dosing and safety data are not available from the provided information.
How it works
Vitamin B6 is a water-soluble vitamin that plays a role in over 100 enzyme reactions, mostly related to protein metabolism. For the calcium ingredient in the data, it supports bone mineralization and neuromuscular relaxation [NIH ODS]. Since this product is B6, the mechanism of action for B6 specifically is not detailed in the provided data.
Safety profile
Data not available for B6 side effects from the provided FDA data. The total adverse event reports for all supplements is 592,059, but no specific report count for this product is given [FDA data]. For the calcium ingredient, high levels can cause constipation, nausea, weight loss, and abnormal heart rhythms [NIH ODS].
Our recommendation
We cannot recommend this 250 mg dose of B6 based on the data provided. The standard RDA for B6 is much lower, and doses of 250 mg are considered high and may pose risks for nerve toxicity over time. Consult your doctor before taking this supplement, as specific safety and efficacy data for this exact product and dose are not available in the provided data set.
