Vitamins: Supplements warning – side effects include weight gain

The paper claimed excess vitamins “may trigger obesity through multiple ways, including increasing fat synthesis, causing insulin resistance, disturbing neurotransmitter metabolism and inducing epigenetic changes.”

The study found excess B vitamins in rats may have been causing weight gain in lab rodents.

The study concluded: “Since the late 1930s when vitamins were first used, the human synthetic being has experienced the largest growth in vitamin intake in human history.

“It is possible that excess vitamins, especially B vitamins, may contribute to the development of obesity.

“Vitamin-rich formulas and food fortification with vitamins may, to a large extent, be responsible for the increased prevalence of obesity over the past several decades.”
