Frequently Asked Questions (FAQs)

The recommended daily amount for vitamin C is 75 milligrams (mg) a day for women and 90 mg a day for men.

2. Can I take vitamin C supplement everyday?

It is OK to take vitamin C every day in recommended dosages. Since your body can't produce or store vitamin C on its own, you need to get it through food or supplements. Too much vitamin C, however, can cause side effects.

3. How many 1000mg of vitamin C can I take a day?

The upper limit for vitamin C in adults is 2,000 mg. Individuals with chronic liver disease, gout, or kidney disease are recommended to take no more than 1,000 mg of vitamin C per day. High vitamin C intakes have the potential to increase urinary oxalate and uric acid excretion.
