- Vitamin C is water-soluble, which means the body does not store large amounts of it and regular intake from foods, drinks or supplements helps support daily needs.1
- If vitamins tend to bother your stomach, taking them with food may help reduce nausea or upset stomach.4
- Vitamin C supports immune function, helps the body make collagen and improves absorption of iron from plant-based foods.1
- Emergen-C offers vitamin C products in formats like fizzy drink mixes, gummies and chewables, making it easier to build vitamin C into a daily routine.*
When Is the Best Time to Take Vitamin C?
If you’re wondering when to take vitamin C, the simplest answer is this: for most people, there is no single best time of day to take vitamin C. Vitamin C can fit into a morning, afternoon or evening routine, as long as you follow the directions on your supplement label and take it consistently.3
Also known as ascorbic acid, vitamin C is a water-soluble nutrient found in some foods and available as a dietary supplement.1 Because the body cannot make vitamin C on its own, it is an essential part of your diet.1
What Does Vitamin C Do for the Body?
Vitamin C supports several important functions in the body. It helps support immune function, helps the body make collagen and improves absorption of iron from plant-based foods.1 Collagen is an important component of connective tissue and plays a role in wound healing.1
Vitamin C also acts as an antioxidant, helping protect cells from damage caused by free radicals.1 Free radicals can form when the body converts food into energy and can also come from environmental exposures such as cigarette smoke, air pollution and ultraviolet light from the sun.1
When Should I Take Vitamin C?
The best time to take vitamin C may depend on the product you use and what works best with your routine. Vitamin C can be incorporated into a morning, afternoon or evening routine. Follow the directions on your vitamin C supplement and talk with a healthcare professional if you have questions about when to take it.3
Vitamin C is water-soluble, and higher amounts that are absorbed but not used are excreted in the urine.2 Because the body does not make vitamin C, it needs to come from the diet.1
Should Vitamin C Be Taken with Food?
Vitamin C is a water-soluble vitamin, and Cleveland Clinic notes that water-soluble vitamins can be taken on an empty stomach with a glass of water.3 However, if vitamins tend to bother your stomach, taking them with food may help reduce nausea or upset stomach.4 Always follow the directions for the specific vitamin C product you choose.
Does Timing Matter When Taking Vitamin C?
Time of day is usually less important than choosing a supplement routine that works with your schedule and product directions.3 If you take multiple supplements or medications, talk with a healthcare professional about the timing that makes sense for your routine.
How Can I Get Vitamin C Every Day?
Because the body does not make vitamin C, it needs to come from foods, drinks or supplements.1 Fruits and vegetables are the best food sources of vitamin C, including citrus fruits, red and green peppers, kiwifruit, broccoli, strawberries, cantaloupe, baked potatoes and tomatoes.1
