Description
With each daily dose, you get a targeted blend of magnesium, zinc, and vital vitamins that play a crucial role in muscle, nerve, and cardiovascular health.
Magnesium is a key player here, offering 200mg per serving to support muscle and nerve function while helping to reduce the likelihood of cramps and fatigue. Meanwhile, the inclusion of zinc enhances immune system function and aids in post-exercise recovery, helping you bounce back quicker between sessions. Vitamins D3 and K2 work synergistically to promote optimal bone density and cardiovascular efficiency, making them especially valuable for athletes who train regularly and intensely.
These easy-to-take capsules are ideal for consistent daily use, especially during periods of hard training where nutritional needs are at their peak. Each bottle contains 60 capsules, offering a full month’s supply based on the recommended dosage of two capsules per day. Whether taken before, during, or after activity, Roctane Magnesium Capsules serve as a reliable foundation for endurance support and long-term athletic performance.
How does it work
Roctane Magnesium Capsules provide a carefully formulated combination of micronutrients essential to athletes under heavy training load. Magnesium plays a central role in muscle contraction and relaxation, and its deficiency is often linked with cramping and fatigue. By supplementing magnesium alongside zinc, critical for recovery and immune defence, you can maintain training consistency without the setbacks of overexertion.
The addition of Vitamin D3 and K2 further supports your body's structural and cardiovascular systems. Vitamin D3 enhances calcium absorption for stronger bones, while K2 helps direct calcium to the right areas, avoiding arterial build-up and supporting heart health. Together, this combination promotes performance longevity and overall physical wellbeing.
