Vitamin B6 20 mg (pyridoxal-5'-phosphate)

Vitals Vitamin B6 20 mg (pyridoxal-5'-phosphate) in a pack of 100 capsules. This supplement provides high-quality vitamin B6 in the form of pyridoxal-5'-phosphate for optimal absorption. Suitable for daily use to support your general well-being. Vitamin B6 also plays a role in the immune system because, as a coenzyme, it is required in the production of certain immunoglobulins (antibodies produced to render viruses or bacteria harmless) and cytokines (substances that send signals to activate or inhibit the immune system). In addition, it contributes to the production of cysteine and the production and breakdown of homocysteine. Finally, vitamin B6 helps regulate the activity of hormones. High doses of vitamin B6 can occasionally cause tingling or numbness in the hands or feet. Hence, the maximum safe upper limit for vitamin preparations in the Netherlands is 21 mg per day for adults. Research is underway to determine whether these occasional cases occur only with vitamin B6 in the form of pyridoxine-HCL and not, or to a lesser extent, with pyridoxal-5'-phosphate. Indeed, there is evidence that only pyridoxine in high doses is toxic to nerve cells and not P5P.
