Characteristics of interactions |
| Iron |
Calcium, Zinc |
 |
Reduces the absorption of iron. |
| Vitamin A |
 |
Increases the absorption of iron. The level of hemoglobin is higher if iron and vitamin A are taken together than in case of iron alone. |
| Vitamin C |
|
Increases the absorption of iron by enhancing absorption in the gastrointestinal tract. |
| Calcium |
Vitamin D |
|
Increases bioavailability of calcium, potentiates calcium absorption by bone tissue. |
| Magnesium |
|
Reduces absorption of calcium. |
| Zinc |
|
Reduces absorption of calcium. |
| Magnesium |
Vitamin B6 |
|
Promotes absorption of Magnesium into the body, and enhances the absorption and retention of Magnesium into the cells. |
| Calcium |
|
Reduces absorption of Magnesium. |
| Manganese |
Calcium, Iron |
|
Impairs absorption of Manganese. |
| Copper |
Zinc |
|
Reduces absorption of Copper. |
| Molybdenum |
Copper |
|
Reduces absorption of molybdenum. |
| Zinc |
Vitamin B9(Folic Acid) |
|
Inhibits absorption of zinc due to the formation of insoluble complexes. |
| Calcium,Iron,Copper |
|
Reduces absorption of zinc in the intestines. |
| Vitamin B12 |
|
Increases absorption of zinc. |
| Chromium |
Iron |
|
Reduces absorption of chromium. |
| Vitamin A |
Vitamin C,E |
|
Protects Vitamin A from oxidation. |
| Zinc |
|
Required for the metabolism of vitamin A and for its transformation into an active form. |
| Vitamin B1 |
Vitamin B6 |
|
Slows the transformation of vitamin B1 to its biologically active form. |
| Vitamin B12 |
|
Enhances allergic reactions to Vitamin B1.Cobalt ions in the molecule of cobalamin contribute to the breakdown of vitamin B1. |
| Vitamin B6 |
Vitamin B12 |
|
Cobalt ions in the molecule of cobalamin contribute to the destruction of Vitamin B6. |
| Vitamin B9 |
Zinc |
|
Inhibits absorption of vitamin B9 due to the formation of insoluble complexes. |
| Vitamin C |
|
Promotes conservation of Vitamin B9 in tissues. |
| Vitamin B12 |
Vitamin C, B1, Iron, Copper |
|
Turns vitamin B12 into useless analogs. |
| Vitamin E |
Vitamin C |
|
Restores oxidized vitamin E. |
| Selenium |
|
Enhances the antioxidant effects of each other. |
