The normal diet usually provides adequate iron for the average person. If the balance is disturbed by poor diet, failure of absorption, or excessive loss (e.g. through menstruation) an iron deficient state develops. Ferrograd C's prolonged release action means that one tablet a day allows release of the iron over several hours and reduces the likelihood of unpleasant side effects such as stomach upset. Ferrograd C also contains vitamin C, which enhances iron absorption. This product is suitable for women and is available in a pack of 30 prolonged release tablets.
