Over 50% of American adults take dietary supplements, believing more is always better for their health. However, excessive intake, particularly of certain vitamins, can have far-reaching consequences and may damage the heart.

For most healthy adults, the Tolerable Upper Intake Level (UL) for vitamin C is 2,000 mg per day. Therefore, consuming 5000 mg of vitamin C daily is significantly over the recommended limit and may pose health risks. While vitamin C is water-soluble and not stored in the body, megadosing can lead to unpleasant and potentially serious side effects.
