Daily vitamin C supplementation is generally safe when taken in appropriate doses. However, high doses may cause acidity, nausea, abdominal cramps, and diarrhoea. Long-term excessive intake may increase the risk of kidney stones in susceptible individuals.
Advice: Prefer natural sources such as amla, guava, oranges, and lemons. If supplementation is required, a low-dose vitamin C supplement (e.g., 100–200 mg daily) is usually sufficient for most adults, depending on dietary intake and individual needs. Avoid unnecessary high-dose supplementation, especially if you have kidney disease or a history of kidney stones.

Vitamin C is generally very safe when taken daily at the usual amount found in standard supplements, since it's water-soluble and any extra is simply passed out in urine. Taking much higher amounts for long periods can occasionally cause stomach upset, diarrhoea, or kidney stones in people who are prone to them.
Next Steps
A standard daily vitamin C tablet from any reputed pharmacy brand works fine for general use, so there's no need to chase a specific "best" product. Getting enough from citrus fruits, amla, and vegetables covers most people's needs too.
Health Tips
If you have a history of kidney stones, please check with a physician before starting any vitamin C supplement regularly.
