Handy liquid electrolyte supplement for very hot days, excessive sweating or strenuous exercise.

When a horse sweats a lot, not only fluid is lost, but also essential minerals or electrolytes. These are essential for a good fluid balance in the body. By replenishing these lost electrolytes you can prevent or significantly reduce the risk of dehydration and acidification. Using purified seawater, Duval Relyte+ supplies a special plasma composed by nature of salts such as sodium, potassium, calcium and magnesium. Seawater is 98% identical to blood plasma with regard to the composition of mineral salts and by giving this supplement you prevent you from overdosing on certain salts. The hypertonic solution is pure unadulterated seawater in its natural form with all its mineral (+-90 species!) components.

In addition, the best natural absorbable form contains Vitamin E (RRR-alpha-tocopherol) and vitamin C has been added. Vitamin C is very important for exercise and muscle support. Vitamin E supports the removal of muscle waste such as lactic acid. In addition, it is very important for healthy muscle function, it supports efficient muscle metabolism.
