Excessive and unsupervised consumption of vitamin supplements can cause serious adverse health effects, which could worsen if combined with other medications without medical supervision, warned the Ministry of Health, thru the General Directorate of Medicines, Supplies, and Drugs (DIGEMID in Spanish).

Among these harmful effects can be overdoses, known as hypervitaminosis, whose consequences range from nausea, fatigue, and neurological disturbances to severe liver damage. This occurs due to the accumulation of vitamins in the body, especially the fat-soluble ones like A, D, E, and K.

These complications can be intensified by drug interactions, as vitamins have the potential to alter other treatments, either by nullifying their efficacy or increasing their toxicity.
