Vitamin B6 (pyridoxine) is involved in over 100 enzyme reactions in the body, primarily related to protein metabolism, neurotransmitter synthesis, and immune function. Adequate B6 is critical for producing serotonin, dopamine, and GABA — key brain chemicals that regulate mood and sleep. Both deficiency and excessive supplementation can cause peripheral neuropathy, making monitoring important for those taking B6 supplements.
Vitamin and nutrient testing identifies deficiencies that can drive fatigue, immune dysfunction, neurological symptoms, and long-term disease risk — and confirms that supplementation is working.
Anyone with restrictive diets (vegan, low-fat, low-carb), malabsorption conditions, fatigue, hair loss, mood changes, or currently supplementing and wanting to verify dosing.
