Vitamin D deficiency has been shown to affect iron status via decreased calcitriol production, translating to decreased erythropoiesis. Between-group analysis showed a clinically significant increase in serum 25(OH)D (p = 0.001) and decrease in iron (p < 0.001) in the tablet group.
Accordingly, what vitamins should you not take with iron?
You shouldn't take iron supplements with milk, caffeine, antacids, or calcium supplements. These can decrease the amount of iron that is absorbed. Try to take your iron supplement with vitamin C (for example, a glass of orange juice) to increase absorption.
Secondly, can you take vitamins and iron pills together?
Never take more than the recommended dose of multivitamins with iron. Avoid taking any other multivitamin product within 2 hours before or after you take multivitamins with iron. Taking similar vitamin products together at the same time can result in a vitamin overdose or serious side effects.
Can you take a multivitamin and vitamin D together?
Similarly, if you take a separate supplement with vitamin D, A, E, or K, take it at a different time of day than your multivitamin because it may reduce absorption of other fat-soluble vitamins in your multivitamin.
What happens when you have low iron and vitamin D?
Some studies concerning bone tissue indicate that iron deficiency is a risk factor for both impaired vitamin D and bone metabolism in humans [37,38]. The present results are in line with this relationship, because, in our study, iron deficiency was also related to the worsening of vitamin D status.
