Vitamin B6 Supplements Efficacy and Risk:Benefit Criteria Preliminary Data from the Society for the Promotion of Nutritional Therapy

For food supplements used for non-medicinal purposes (ie. to supplement the diet), the concept of efficacy relates to the product’s ability to function in the manner which would be expected from it: in this case to prevent functional deterioration associated with insufficient dietary vitamin B6. Such deterioration can manifest in many and varied ways owing to this vitamin's role in numerous physiological and biochemical functions. Since individual manufacturers have different quality control standards, it is difficult for us to comment generally on the efficacy of the vitamin B6 products on the market. We understand that from time to time the Food Ministry conducts tests on product samples to ensure that quality standards are upheld, and we are aware of no adverse reports about the efficacy of individual vitamin B6 products.
