LifeSource Vitamins ZMA® — Zinc Magnesium Vitamin B6 — 90 Veg Capsules — Supports Sports Recovery, Muscle Function & Sleep Quality*
LifeSource Vitamins ZMA® (Zinc Magnesium Vitamin B6) combines three essential minerals in precise ratios designed to support athletic recovery, muscle function, and sleep quality. This scientifically formulated supplement delivers zinc monomethionine aspartate, magnesium aspartate, and vitamin B6 to help replenish nutrients depleted during intense physical activity while supporting natural recovery processes and restorative sleep.* Zinc plays a central role in cellular growth, tissue repair, and immune function, while magnesium supports energy production, electrolyte balance, and neuromuscular function. Vitamin B6 enhances amino acid metabolism and contributes to proper nervous system function. Physical activity increases the body’s need for these essential minerals, making ZMA® an ideal supplement for active individuals seeking to optimize their recovery and performance.
