    Product Overview


    • Dietary Supplement
    • The Bioactive form of Vitamin B6
    • The Active form of Vitamin B6 more Readily Used by the Body
    • Pyridoxal 5'-Phosphate is Yeast Free

    Pyridoxine, also known as vitamin B6, is necessary for the transformation and utilization of amino acids for many functions in the body, including energy production and neurotransmitter synthesis. Vitamin B6 is also involved in the production of hemoglobin, intrinsic factor, and is a vital component in the formation of the myelin sheath that surrounds nerve cells. But in order for pyridoxine to be used by the body it must first be converted to pyridoxal 5'-phosphate (P5P), a process that takes place in the liver. Individuals with compromised liver function have difficulty making this conversion and consequently may be at risk of a vitamin B6 deficiency. Supplementing with Thorne's Pyridoxal 5'-Phosphate ensures you receive the most bioactive form of vitamin B6.

    Great product

    Posted by iHerb Customer on Jan 07, 2018 | Verified Purchase

    This is the only type of Vitamin B6 I can take without being sick or feeling toxic. The P5P form of B6 is bio-availalble for me but the form found in most other B6 supplements is pyridoxine which is a poison to me. Because of having inherited triple compound MTHFR genetic variants, I can't break down or convert pyridoxine into a usable form of B6. When I was pregnant and suffering from severe hyperemesis gravidarum (almost continuous morning sickness - vomiting) I was hospitalised and injected with B6 - pyridoxine. I became more sick and had to discharge myself from hospital to escape the worsening of my symptoms. I didn't know about the MTHFR variants at that stage, but now I realise I was being poisoned by the pyridoxine injections and I needed to take P5P form of B6. I highly recommend Thorne P5P capsules. I take them often but am careful to keep working with my doctor when I take any kind of supplement.

    My son has been on this supplement for a few years now. It's clean and very high quality. My daughter and I take another brand p5p, but ,y super sensitive son can take this, no reactions. Worth the cost!
