Professional advice:

  • Do not take in conjunction with a source or supplement of Iron and/or Zinc.

The Importance of Magnesium Capsules for Athletes

Magnesium Caps DUAL are plant-based magnesium capsules for athletes made from Bisglycinate and Citrate, two organic salts with high bioavailability. These magnesium capsules for athletes contain no excipients or additives, offering only magnesium in a plant-based capsule for guaranteed purity and safety.

Why Magnesium is Vital for Athletes

Magnesium is the fourth most abundant mineral in the body, essential for cardiovascular, immune, and hormonal functions. However, many athletes fail to meet the recommended daily intake (400 mg for men and 300 mg for women) due to modern diets and processed food consumption (Mertens, E., 2019; Rosanoff, A., 2012).

Performance Benefits of Magnesium Capsules for Athletes

During physical activity, magnesium needs for athletes increase. This mineral is crucial for muscle contraction and relaxation alongside calcium. It's also key in muscle regeneration and related to hormones like testosterone, helping improve strength and muscle mass. Moreover, magnesium acts in many intracellular enzymes, facilitating energy release.

Magnesium’s Role in Energy and Neuromuscular Function

Magnesium is involved in nerve impulse transmission and is closely linked to neuromuscular function, helping prevent cramps. Alongside calcium, it strengthens bones, teeth, and soft tissues, and supports cell membrane integrity.

EFSA-Recognized Benefits of Magnesium for Athletes

The EFSA (European Food Safety Authority) acknowledges that magnesium helps reduce fatigue, supports energy metabolism, muscle function, protein synthesis, and electrolyte balance. These benefits are crucial when using magnesium for athletes, as it contributes to the health of bones, teeth, and the nervous system.

Bisglycinate and Citrate Combination in Magnesium Capsules for Athletes

Bisglycinate and Citrate are organic salts with high bioavailability, used in our magnesium capsules for athletes. This combination ensures efficient absorption without gastrointestinal discomfort, and optimal magnesium distribution in muscles, bones, and brain.

High Concentration and Purity for Athletes

Each capsule contains 170 mg of pure magnesium, free of excipients and additives. This guarantees high purity without inorganic salts that may cause laxative effects. Additionally, Magnesium Caps DUAL is anti-doping certified by Informed-Sport, offering a safe and high-quality choice for athletes.
