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.

iHerb Customer Reviews
Vitamin B-6 for Noise/Sound/Light Sensitivity, Nerve Support, Pyroluria
I have been using this 500 mg tablet of vitamin B-6 for years. The tablet is smaller than a 500 mg capsule. I appreciate that it is time release. B-6 gives support and soothes the nervous system. I am naturally sensitive to light, sound and various noises. With enough B-6, I don't care if a 747 lands in my living room. B-6 is a necessary co-factor (with vitamin C) to convert the raw material precursor 5HTP (tryptophan) to the neurotransmitter Serotonin. Serotonin is the brain neurotransmitter that is enhanced by Prozac/Paxil/Zoloft and other SSRI's. It is possible that some depression and other problems are nothing more than a B-6 deficiency. B-6 is also necessary for the synthesis of 3 other important brain neurotransmitters. Although this supplement gives 25,000% of the Daily Value, many people need and benefit from this level of supplementation. Also, I have Pyroluria, a genetic condition which causes destruction and excretion of B-6. It is a condition which is often not diagnosed by doctors, although there is a urine test available on the internet for $55. I use 2 or 3 tablets daily to feel good. Without this supplementation, I experience some of the symptoms of B-6 deficiency, such as anemia and fatigue and sensitivities to light and sound. Too much can cause temporary numbness in the toes, which goes away if you decrease the doseage. This is an important part of the B-complex. However, the amount of B-6 in most B-complex supplements is only 100 mg. This is not enough to really get the full benefit of B-6. This is why a 500 mg tablet is very useful. Also my wife found it valuble to treat morning sickness during pregnancy. Staatsburg, New York.

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!
