Studies show that more than 50% of all women runners are deficient in iron*. Low iron levels result in fatigue and poor endurance since the blood is unable to carry oxygen as efficiently to working muscles. Sensitivity to the cold is another sign that your iron may be low. The highest loss of iron per day in top class athletes can be up to 2mg. Female distance runners usually get less than the recommended daily allowance of 15mg.
But you don’t have to be a professional runner to be iron deficient. Anyone who takes regular exercise or does a physically demanding job could require extra iron to compensate for the iron used during high-energy expenditure.
In physically active people, iron levels can be depleted in numerous ways. Losses in sweat can, in extreme cases, account for 50% of the average daily iron requirement for a man. That is because as much as one litre of water containing up to 0.5mg of iron, can be lost an hour during a hard workout.
A combination of foot strike destruction of red blood cells (red cells are broken by trauma as they pass through the foot during exercise), natural wastage and in females, menstruation can easily lead to a fast depletion of iron levels.
Since Spatone is a 100% natural iron supplement and contains no additives whatsoever it particularly suits you if you are concerned about a natural healthy lifestyle.
