Overview

Nutricost Vitamin B6 provides 100mg of pyridoxine hydrochloride per capsule. Vitamin B6 is a critical coenzyme in over 100 enzymatic reactions, most notably the synthesis of neurotransmitters (serotonin, dopamine, GABA, norepinephrine), hemoglobin formation, amino acid metabolism, and glycogen breakdown. B6 is also essential for the conversion of 5-HTP to serotonin and L-DOPA to dopamine, making it foundational for mood regulation. Additionally, B6 plays a role in hormonal balance — it's commonly recommended for PMS symptoms and morning sickness during pregnancy. The 240-capsule count provides an 8-month supply at $0.05 per serving.

Our Verdict

7.4/10 — Good

Nutricost B6 is the budget neurotransmitter support — 100mg pyridoxine for 240 servings at $0.05 each. Essential for serotonin and dopamine synthesis; consider cycling or using lower doses for long-term use as 100mg is the tolerable upper limit.
