Is taking one vitamin C every day harmful to the body

Taking moderate amounts of vitamin C daily is usually harmless to the body, but long-term overconsumption may cause adverse reactions. The intake of vitamin C needs to consider individual differences, dietary sources, and supplement doses.

Vitamin C is a water-soluble vitamin, and the excess will be excreted in urine. A daily intake of no more than 2000 milligrams by healthy individuals generally does not cause harm. Moderate supplementation can help enhance immunity, promote collagen synthesis, and antioxidant properties. Citrus fruits, broccoli, kiwifruit and other foods rich in vitamin C in daily diet can meet the needs of most people. For people who smoke, experience high stress, or have weak digestive and absorption functions, the dosage can be appropriately increased under the guidance of a doctor. Long term daily intake exceeding 1000 milligrams may increase the risk of diarrhea, gastrointestinal discomfort, or urinary system stones. Some populations, such as kidney stone patients, carriers of hemochromatosis genes, and patients with glucose-6-phosphate dehydrogenase deficiency, need to strictly control their intake. Vitamin C may interfere with the blood glucose test results. Before taking it, diabetes patients should consult with some drugs, such as anticoagulants and aluminum preparations, which may affect the efficacy.

It is recommended to prioritize obtaining vitamin C through natural foods and assess daily dietary intake before taking supplements. Special populations or long-term users should regularly monitor their urine routine and kidney function. When symptoms such as persistent abdominal pain, frequent urination, and urgency occur, seek medical attention promptly. Maintaining a balanced diet and avoiding vitamin C supplements as daily necessities are essential for maintaining health more safely and effectively.
