Liquid magnesium cramps box from Nutrisport is a food supplement in gel format formulated with magnesium citrate (maximum bioavailability), Vitamin B6 (improves the absorption of magnesium) and Fructose (low glycemic index sugar that will prevent glycemic alterations during exercise). Magnesium is a basic mineral in the athlete's diet. The physical wear and tear caused by exercise implies imbalances that we must take into account to avoid subsequent problems that may negatively affect our performance. In those aerobic exercises that involve greater sweating, the loss of magnesium (among other electrolytes) is important. Magnesium is essential in both strength and endurance sports, as it contributes to muscle contraction and relaxation mechanisms as well as recovery processes and the nervous system. Muscle cramps and pain, for example, can be a consequence of a magnesium deficiency. It is recommended to take 1 gel before bed as a muscle relaxant on days of heavy physical exertion. Sporadic supplementation: 1 gel before and/or during exercise to avoid cramps. Preparation for long distance competitions: 1 gel per day for the previous 5 days. During competition: Between 1 and 3 magnesium gels depending on physical wear and sweating. Do not exceed the recommended daily dose. Food supplements should not be used as substitutes for a varied and balanced diet. A healthy lifestyle is important. Keep out of the reach of children. Store in a cool, dry place.
