Doctor Explains Why Magnesium Supplements May Upset Your Stomach

Why are magnesium supplements making you sick? A recent video by Spanish doctor and health influencer Isabel Vina (@isabelvina) has gone viral, explaining why many people experience gastrointestinal distress after taking magnesium supplements. Vina, who hosts the podcast "Tus amigas las hormonas," points to two key factors. First, she warns against taking excessive doses of elemental magnesium. "More than 100-200 milligrams can cause problems due to the osmotic effect," she explains, noting that it draws water into the intestines. Second, she stresses the importance of supplement type. Vina recommends bisglycinate, malate, or taurate forms over oxide or citrate, which are more likely to cause discomfort. The video has already garnered thousands of views and numerous comments, highlighting the widespread concern about magnesium supplement side effects. Vina's advice offers a practical guide for consumers seeking to improve their health through magnesium supplementation.
