Product Overview


  • Vitamin Supplement
  • Timed Release

Vitamin B-6 is an essential nutrient which is required for the metabolism of lipids, carbohydrates, and proteins. It facilitates the conversion of amino acids from one to another as needed, and is necessary for normal synthesis of hemoglobin and for the normal function and growth of red blood cells. It is also needed for the synthesis of neurotransmitters and for converting essential fatty acids into prostaglandins (chemical messengers). This product provides a gradual release of vitamin B-6 over a prolonged period of time for improved absorption and assimilation.

Suggested Use

1 tablet daily. Do not exceed suggested use.

Excellent, no more nausea

Posted by Reviewer1893600 on Jun 20, 2015

Seven out of eight members of my family require high doses of B6 for Pyroluria. We all suffered nausea until using this slow release form... no more problems now.

Tablet allows you to snap in half if you need less B6 on a given day. High quality

Does not work at all, cannot be metabolized with impaired liver

Posted by PurplePegasus on Feb 12, 2013

I have liver illness. I bought this because of the top reviewing comment here but it does not work. It doesn't do anything at all. I will go back to the P5P/PAK activated B6 from Country Life which doesn't need to be metabolized by the liver. This pill is a nightmare for me. I'm on edge, neighbors being driving me up the wall for 3 days in a row and I can't calm down with this. It's a useless pill for me, maybe even toxic. The timed-released coating, even when broken in half, completely prevents digestion and metabolizing. No good, zero stars!
