Six signs your vitamin habit might be doing more harm than good
A Daily Mail health piece warns that while many Americans take dietary supplements, taking too much can cause fatigue, gastrointestinal issues (like bloating and diarrhea), dizziness or headaches, heart palpitations, skin discoloration from beta‑carotene/vitamin A, and sleep disturbances. Experts note that excessive intake of vitamins such as D, B6, B12, C, magnesium, iron, and retinol can overload the body, with limits like vitamin D up to 4,000 IU/day and iron around 45 mg/day; reducing intake and watching for persistent symptoms is advised.
