Iron deficiency knows no boundaries – from women (it is estimated that up to 26% of reproductive aged women are iron deficient), to athletes, the elderly, and vegetarians – shortage of this mineral is widespread. Iron is an essential element for the body, and when it’s low, energy levels decrease. Other tell-tale symptoms include: weakness, pale skin, dark under-eye circles, brittle hair and nails, shortness of breath, and cold hands and feet. Think you may be deficient? Try a natural liquid iron supplement. It will help fight back against iron deficiency by promoting the formation of healthy red blood cells.
