Consequently, Dr Philip NGO, a pharmacist who has more than ten years of experience in community pharmacy, explains this mechanism: “For example, iron absorption can be slowed down by caffeine and caffeine can impact certain nutrients via its diuretic properties.” This interaction can become particularly problematic for water -soluble vitamins. Nevertheless, which are not stored in the body in the long term and can be eliminated by urine before being fully absorbed.

Tanins present in coffee can also be linked to certain mineral supplements, preventing their correct absorption in the body.

B2, B7, B9 and B12) play crucial roles in various bodily functions and are often taken in the form of supplements to overcome deficiencies or support general health.
