![Is It OK to Take Vitamin C Every Day](https://images.medicinenet.com/images/article/main_image/best-vitamin-c-serum.jpg?output-quality=75)
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. Learn about the upper limits of vitamin C intake, how much you should have each day, and good sources to include in your diet.
What is vitamin C?
Vitamin C, also called ascorbic acid, is an important micronutrient that belongs to the water-soluble group of vitamins that includes folate and other B vitamins.
Vitamin C is a powerful antioxidant, which means that it protects cells and tissues from free radical damage. It also helps synthesize important substances, such as collagen protein, in the body.
What are the upper limits of vitamin C intake?
Daily upper limits for vitamin C include that which is obtained from all sources—food, beverages, and supplements. Experts recommend that most of your vitamin C needs should be met through your diet.
Age group | Upper limit (mg) |
---|---|
0 to 12 months | Not known |
1 to 3 years | 400 |
4 to 8 years | 650 |
9 to 13 years | 1200 |
14 to 18 years | 1800 |
19 years and older | 2000 |
Your upper limit of vitamin C may vary depending whether you have any underlying conditions. For example, if you have chronic kidney disease, chronic liver disease, a history of kidney stones, or gout, you must not take more than 1000 mg of vitamin C per day.
If you are pregnant, you should also avoid Vitamin C supplementation in large doses because it can cause vitamin C deficiency in the baby after delivery.
How much vitamin C should you have each day?
Your daily vitamin needs vary depending on your age, gender, and overall health. For example, exposure to secondhand smoke may increase your vitamin C requirements.

0 to 6 months | Males | 40 | ||
Females | 40 | |||
