Description

Optimum Nutrition ZMA is a synergistic combination of Zinc, Magnesium, and Vitamin B6 designed to enhance muscle recovery, support anabolic hormone levels, and promote deep, restful sleep. Formulated specifically for hard-training athletes and active individuals, this high-potency mineral blend helps replenish key micronutrients depleted during intense physical activity so you wake up fully recovered and ready to perform.

Key Benefits & Features

  • Supports Muscle Recovery: Delivers bioavailable zinc and magnesium to accelerate tissue repair and reduce post-workout soreness.

  • Promotes Restful Sleep: Helps calm the central nervous system to improve sleep quality, ensuring complete physical and mental overnight recovery.

  • Hormonal & Testosterone Support: Helps maintain optimal free testosterone and anabolic hormone levels in training individuals.

  • Enhanced Absorption: Features high-quality zinc L-monomethionine and magnesium aspartate along with Vitamin B6 for optimal bioavailability.

  • Convenient Capsule Delivery: Easy-to-swallow capsules provide precise daily dosing without any mixing required.

How It Works

Intense exercise and daily stress significantly increase the body’s loss of critical trace minerals through sweat and metabolic consumption. Zinc plays a crucial role in cellular growth, tissue repair, and immune system function, while magnesium is essential for neuromuscular transmission, protein synthesis, and maintaining fluid balance.

Optimum Nutrition ZMA combines these two vital minerals with Vitamin B6, which acts as a co-factor to optimise mineral absorption and utilization at the cellular level. By taking ZMA prior to sleep, it supports natural hormone production during night-time recovery cycles and promotes deeper sleep stages where peak physiological repair occurs.

Recommended Use

Men should take 3 capsules daily. Women should take 2 capsules daily. For best results, consume 30–60 minutes before bedtime on an empty stomach. Avoid taking ZMA alongside dairy or calcium-rich foods or supplements, as calcium can inhibit zinc and magnesium absorption.
