Description: Douglas Dietary Carbonyl Ironis essentially pure iron (98%) unlike most other iron supplements which contain iron salts such as iron fumarate and iron gluconate. Iron is used by the body to transport oxygen, and to enable the body to breakdown (oxidize) food components such as starches, sugars and fats to release energy (calories). Iron is also the essential component of haemoglobin in the red blood cells which carry oxygen from the lungs to the tissues. Studies indicate that people with better iron levels are more likely to achieve their mental and physical potential. If your iron levels are too low, you may experience tiredness, lethargy and difficulties concentrating. Carbonyl Iron tablets can provide your body with sufficient iron for 3/4 of the maximum recommended daily amount in a single tablet. Ingredients: Each Tablet Provides: Carbonyl Iron 18mg No added:Preservatives, sugar, starch, gluten, yeast or milk derivatives. Directions: Simply: Take 1 tablet daily.
