For generally healthy adults, the benefits of routine vitamin and mineral supplements in preventing cardiovascular disease, cancer, or early death are minimal. However, the timing of supplement intake can significantly affect the absorption of certain nutrients, particularly iron, vitamin D, and vitamin B12.
Key Insights
Routine vitamin and mineral supplements offer little protection against cardiovascular disease, cancer, or early death for generally healthy adults. The timing of supplement intake can affect absorption, particularly for iron, vitamin D, and vitamin B12. Notably, iron absorption can be reduced by coffee, calcium, and food, while vitamin C can increase absorption. These findings underscore the importance of considering individual circumstances, such as diagnosed deficiencies or interactions with other medications, when deciding to take supplements.
