Overview

Nutricost Vitamin B6 provides 100mg of pyridoxine HCl per capsule in a 240-count bottle. Vitamin B6 is a critical cofactor in over 100 enzymatic reactions, including the synthesis of neurotransmitters (serotonin, dopamine, GABA, norepinephrine), hemoglobin, and amino acid metabolism. B6 deficiency is common in older adults, those on certain medications (oral contraceptives, isoniazid), and those with poor dietary intake. The 100mg dose is therapeutic-level (the RDA is only 1.3-2mg), commonly used for PMS symptoms, morning sickness, and carpal tunnel syndrome.
