They were separately given a reference dose of Fe ferrous sulfate with ascorbic acid. Results: Iron absorption increased from 5. Conclusions: These data demonstrate an overall benefit to iron absorption from ferrous fumarate provided with orange juice.
The special, patented formula in Feosol Complete maximizes iron absorption while minimizing GI side effects. In most cases, the best time to take iron supplements is about one hour before or two hours after meals.
Iron supplements are best taken with water on an empty stomach. There is a long list of foods, such as coffee, tea or milk, which interfere with the absorption of ferrous iron. Consider this fact next time you are about to pop an iron pill right before breakfast: taking your iron supplement with food may decrease how much iron is absorbed by the body by up to 50 percent!
On the flip side, citrus items, such as lemonade, can increase your iron absorption. The no-food guideline is true for non-heme forms of iron, including ferrous sulfate, ferrous fumarate and ferrous gluconate; the exception to the rule is a heme iron supplement, such as Feosol Complete with Bifera, which combines heme and non-heme in one pill! Feosol Complete is versatile and can be taken with or without food.
Since oral iron products may interfere with absorption of certain antibiotics, these products should not be taken within two hours of each other. Ideally, most iron supplements should not be taken with food. The reason you should take iron on an empty stomach without food is that an acidic stomach helps with iron absorption.
Unfortunately, many people find that iron upsets their stomachs, so they take iron with meals to try and offset side effects such as nausea. Your doctor might also recommend that you take your iron supplement with a glass of orange juice because vitamin C improves the absorption of iron.
As you can see from the list above, there are many food items that can decrease the absorption of non-heme iron, from fruit and nuts to dairy and whole grains! That makes it very difficult to take your iron supplement with a big glass of milk and a hearty bowl of cereal. One exception to the rule is Feosol Complete with Bifera. Because of its unique dual-iron formula that includes both heme and non-heme iron , you do not have to avoid food when you take it.
You can take it any time of day — breakfast, lunch or dinner — with or without food.

Ascorbic acid enhances iron absorption. However, children reportedly prefer noncitrus juices eg, apple juice , which contain little vitamin C, over citrus juices eg, orange juice with high vitamin C content.
Previous studies have not established whether apple juice consumption by children reduces iron absorption, and thus increases the risk of pediatric iron deficiency, compared with consumption of orange juice. This study demonstrates that young children absorb iron well from a meal that includes either apple juice or orange juice.
Thus, our findings imply that a child's preference for apple juice over orange juice with a meal will not have an adverse effect on iron absorption or lead to iron-deficiency anemia, a significant health problem that persists worldwide.

Hallberg LBrune MRossander L Effect of ascorbic acid on iron absorption from different types of meals: studies with ascorbic-acid-rich foods and synthetic ascorbic acid given in different amounts with different meals. Hum Nutr Appl Nutr. Heme and nonheme iron are the two dietary forms of iron.
Heme iron is found in meat and is the most bioavailable form, as 20 to 30 percent is absorbed. Nonheme iron is primarily found in plants and is less soluble. Only 1 to 10 percent of it is absorbed. Vitamin C -- or ascorbic acid -- is the strongest iron enhancer, reducing ferric iron to ferrous iron. The primary iron inhibitors in the diet include tannins, such as tea and red wine, and phytates, such as nuts, seeds, grains and cereals.
