Excess Vitamin C Harms: Nutritionist Warns

Social media trends promoting high-dose Vitamin C supplements for benefits like improved skin and immunity are misleading, according to nutritionist Nmami Agarwal. She cautions that the body can only absorb a limited amount of Vitamin C, with excess potentially converting to oxalates. Elevated oxalate levels are linked to an increased risk of kidney stone formation, particularly for those already prone to them.

Furthermore, consuming excessive Vitamin C daily can lead to digestive discomfort, including symptoms such as acidity, nausea, diarrhea, and stomach cramps. Agarwal stresses that supplements are intended to fill nutritional deficiencies when necessary and should not be treated as beauty products or viral wellness fads. She advises individuals to consult with a doctor or qualified nutritionist before beginning any supplement regimen, especially at high doses, to ensure the right dosage for their body's needs.
