SPONSER Magnesium Plus contains fructo-oligosaccharides and soluble food fibres strengthening the immune system and promoting the digestion as well as the absorption of magnesium. Magnesium plays a major role in the contraction of muscles as well as in the metabolism of energy. It is especially important for sports people and also vigorous people of all ages. A sufficient magnesium supply can actively prevent muscles from contracting and can also increase the load tolerance. Physical activities entailing a high loss of sweat increases the need for magnesium and justifies an intake of such complements.
