Slow-Mag Performance 15 Effervescent Tablets

Slow-Mag Performance is the sports version of South Africa's best-known magnesium. It combines magnesium with electrolytes in an effervescent drink for use before, during or after exercise. It replaces what is lost in sweat and supports muscle function, energy and recovery. Magnesium sits at the centre of energy metabolism, nerve conduction and muscle relaxation, and it helps the body regulate calcium, potassium and vitamin D. Sodium, potassium and glucose in the right ratio are absorbed together in the gut, pulling water with them, which rehydrates the body faster than water alone.

Every litre of sweat takes magnesium and sodium with it, and cramps in the last kilometres of a race are the result. If you train hard, sweat a lot, take a water tablet or a stomach-acid reducer, or simply wake up with calf cramps, your magnesium stores are probably running behind what your muscles and nerves use each day.
