Magnesium is a mineral that is crucial for energy production, muscle contraction, nerve impulse transmission, and bone mineralisation. Magnesium can be found in a number of foods and is most prevalent in green leafy vegetables such as spinach, nuts and grains. Magnesium has a number of important functions in the human body including turning the food we eat in to energy and ensuring correct endocrine system function to promote healthy bones. Magnesium is also required as a cofactor for over 300 enzyme systems. Among the systems catalyzed by these enzymes are fatty acid synthesis, protein synthesis, and glucose metabolism. From an athletic perspective it is required for metabolism of carbohydrates, proteins and fats for energy. As part of its role in the activity of enzymes, it is involved in the transmission of nerve impulses and myofibril contractions. Therefore, Magnesium can play a pivotal role in the production of energy for both anaerobic and aerobic exercise. Magnesium Citrate is a highly bio-available form of Magnesium which allows greater uptake in to your system. Our Magnesium Citrate is standardised to approximately 15% Magnesium content. Warnings: Magnesium Citrate can have a laxative affect, so you may need to alter our ‘Suggested Use’ to meet your personal needs. If you do experience these affects it is recommended that you reduce your dosage size.
