Isotonic Drink Benefits

Sweating is the way in which the body maintains its core temperature at 37 degrees centigrade. This results in the loss of body fluid and electrolytes (minerals such as chloride, calcium, magnesium, sodium and potassium) and if unchecked will lead to dehydration and eventually circulatory collapse and heat stroke. The effect of fluid loss on the body is as follows.

An isotonic beverage is a sport drink whose osmolarity is between 250 mOsm/L and 340 mOsm/L. VEROFIT Isotonic has an osmolarity of 315 mOsm/L. And what is osmolarity? It is the concentration of particles in the blood. In this case, we are looking for a similar concentration of particles in the drink to what is found in the bloodstream( the human body has an average osmorality of 250 mOsm/L and 340 mOsm/L), so that its absorption will be faster and will require less extra energy from the body for its assimilation.

sotonic sports drinks - Lucozade Sport etc. - provide fluid, energy and electrolyte replenishment. These components are depleted during exercise due primarily to an increased perspiration level - we literally sweat these elements out out.

Of course fluid (water) replacement is important - if water isn't replaced in our exercising system we rapidly dehydrate and in extreme cases exercise must cease completely. In more normal cases exercise performance dips far below an optimal level.

Electrolytes are essentially salts lost in sweat. Replacing them will aid the digestion and osmosis of fluid absorbed into body's working muscles -
without them the fluid within the drink will not be fully absorbed and the effects of dehydration will still soon rear their ugly head.
