Active people are often very interested in optimizing their diets to be as healthy as possible. A healthy diet that meets all your vitamin and mineral requirements can help you meet your health, energy, and performance goals. Vitamin C is an essential nutrient in the human diet because it isn't produced naturally in the body. Though vitamin C deficiency isn't common, not everyone consumes a healthy diet with plenty of vitamin C-rich fresh fruits and vegetables every day. Supplements aren't a substitute for a healthy diet, but they can fill in the gaps while you work on diet quality.

What is Vitamin C?
Vitamin C is a water-soluble vitamin, which means that it dissolves easily in liquid. Another name for vitamin C is ascorbic acid. It's an essential nutrient in the body because the body isn’t able to produce its own. Vitamin C has to be derived from your diet or supplemented.
What Does Vitamin C Do?
Vitamin C has many functions.(8) In the body, vitamin C acts as an antioxidant, which means it helps protect the cells from damage from natural body processes and from the environment. Vitamin C is also essential to the formation of collagen, which helps your body heal wounds and absorb iron.
The benefits of vitamin C include:
- May lower the risk of cancer when the source is fruits and vegetables, but it's unclear if this is directly related to vitamin C itself
- May help lower the risk of cardiovascular disease
- May slow the progression of age-related macular degeneration and cataracts
- May slightly decrease the duration of a cold or diminish your symptoms, although it will not prevent you from becoming sick
Taking in too much vitamin C can cause gastrointestinal side effects, such as nausea, stomach pain, or diarrhea. Since the body is able to get rid of vitamin C in the urine, most people shouldn't have long-term side effects from taking too much vitamin C. If you take other prescription medications or chemotherapy, you should check with a healthcare provider to make sure there are no interactions with high doses of vitamin C.
What is the Best Natural Source of Vitamin C?
Vitamin C is widely available in food. The best natural sources of vitamin C include fruits and vegetables. A single medium orange contains about 70 milligrams of vitamin C per serving, which provides most of the Recommended Dietary Allowance (RDA) for most age groups.
According to the National Institutes of Health, the highest sources of vitamin C in the American diet include:(9)
- Citrus fruits, such as oranges, orange juice, and grapefruit
- Potatoes
- Tomatoes
- Tomato juice
Other good food sources of vitamin C include red and green peppers, broccoli, and strawberries. Some foods, like breakfast cereals, are often fortified with vitamin C.
Vitamin C deficiency is quite rare in modern, developed nations. It would take many weeks of very limited vitamin C intake to develop a vitamin C deficiency. However, vitamin C deficiency leads to scurvy, which can cause bleeding gums, joint pain, poor wound healing, general fatigue, and anemia.
How Much Vitamin C Do I Need?
Most adults meet the RDA for vitamin C fairly easily. You may need to supplement if you can't eat a varied diet or are unable to consume a few fruit and vegetable servings per day. In particular, people who smoke or have medical issues such as some cancers or severe intestinal malabsorption may need supplemental vitamin C.
The RDA for vitamin C is 90 milligrams per day for adult men and 75 milligrams per day for adult women.(10) Note that people who smoke should add 35 milligrams per day to the above amounts. The daily upper limit for vitamin C for adults is about 2000 milligrams per day.
What To Look For in Vitamin C Supplements
Though it's usually best to meet most of your daily vitamin and mineral needs through your daily diet, sometimes supplements are necessary or desired to achieve better health. If you're buying a vitamin C supplement, consider these factors:
- Dose per serving of the supplement: Excessive amounts of vitamin C above the RDA are not necessary for most people.
- Added ingredients: Consider whether there are extra filler ingredients like sugar or if there are other vitamins, minerals, or herb ingredients included.
- The quality of the supplements: Companies that use third-party testing or use facilities that use Good Manufacturing Practices (GMP) usually produce higher-quality products.
If you're unsure if you should be taking a dietary supplement, check with your healthcare provider. It's always a best practice to let your healthcare providers know which supplements you are considering taking and to ask for their dosage or brand recommendations.
Forms of Vitamin C
Vitamin C supplements come in a variety of forms now, including:
- Capsules
- Chewable tablets
- Powders
- Drink mixes
- Gummies
- Liquids and sprays
How Do I Know If I Have a Vitamin C Deficiency?
While rare, vitamin C deficiency can occur due to factors like poor diet, kidney issues, and alcoholism, the latter of which contributes to the most well-known condition caused by vitamin C deficiency, scurvy.(11)
Symptoms of vitamin C deficiency can include fatigue, tooth and gum issues, easy bruising, and dry skin and hair. The best method for determining if you may have lower vitamin C levels is to consult with your primary doctor and have your blood tested.
How Much is Too Much Vitamin C?
The recommended daily amount of vitamin C is 75 milligrams for women and 90 milligrams for men, though you can still take up to 1,000 milligrams per day with little to no side effects. Elevating your vitamin C levels through diet is always ideal and the safest way, but supplements can still be very helpful to hit those dietary requirements. That said, the upper limit for supplemental vitamin C is 2,000 milligrams. Surpassing this limit can lead to side effects like nausea, diarrhea, stomach cramps, and headaches.(12)
Our Final Takeaway
If you are unable to reach your daily vitamin C intake levels through diet alone, supplements can be an easy and very helpful way to close those nutrient gaps. Not all vitamin C supplements are created equal, however, as some may contain forms of vitamin C that aren't as absorbable in the body or are full of added sugars, especially in gummies. If you're looking to supplement with vitamin C, read the labels and get familiar with the ingredients and where your vitamins and minerals are sourced so that you're only putting the best in your body.
FAQs About Vitamin C
When is the best time to take Vitamin C?
It is best to take supplements as part of a regular routine so you remember to take them daily. Though there isn't an optimal time of day to take vitamin C, it may help to take it every day at the same time, such as with breakfast or dinner, so you don't forget to take your dose. In addition, taking vitamin C with food may decrease the risk of gastrointestinal side effects, especially if taking a larger dose.
Does vitamin C help with colds?
Supplementing with vitamin C on a regular basis will not prevent you from getting a cold virus. However, supplementing with vitamin C may shorten the duration of your cold. Supplementing with vitamin C may also decrease the severity of your cold.
What kind of vitamin C is best for your face?
Topical vitamin C that you apply directly to clean skin is best for the face. Look for a vitamin C serum or cream that has up to 20% vitamin C for best results. Regular use of vitamin C serums or creams on the face can help reduce the signs of aging, lighten dark spots, and may even promote skin healing.
What form of vitamin C is best?
Ascorbic acid is the form of vitamin C that is used the most in C supplements. It can be found in capsules, tablets, liquids, or chewables. The best form of vitamin C will be the one that is the easiest for you to take regularly.
Can you take vitamin C while pregnant?
The simple answer is yes, you should be able to take vitamin C while pregnant depending on your doctor's recommendations. Otherwise, you should be able to get your daily vitamin C amounts from a well-balanced diet. Further, studies have shown that vitamin C supplementation while pregnant has little to no effect either way.(13)
