Take a deep breath. Feel the oxygen surge throughout your body? You can thank iron for that.

Iron is a structural component of the hemoglobin found in blood, which delivers oxygen from the lungs to other body tissues. Without it, anemia - caused by iron-deficiency, which affects 240,000 toddlers and 3.3 million women in the United States - can lead to fatigue impaired concentration, and compromised immune function. Over 90% of women ages 12 to 50 don't get the recommended daily amount. Teens (both boys and girls) need it to help them grow strong. Shaklee adds vitamin C for better iron absorption.
