Vitamin B6 (pyridoxine) handles protein breakdown, red blood cell production, and the creation of brain chemicals like serotonin. These jobs make it central to steady energy, mood balance, and a responsive immune system. The vitamin also helps keep homocysteine levels in a normal, healthy range.
Take B6 with food to improve uptake. Most people use it in the morning or early afternoon. Late doses can interfere with sleep.
Long-term, high-dose use can injure nerves. Keep daily intake from supplements under 100 mg unless a practitioner directs otherwise.
