Selecting the right vitamin C supplement depends on a variety of factors, including the form, quality, dose, and price.
You can start by considering how you’ll be using the supplement. For instance, if you prefer to take a pill, you’ll want to check out encapsulated vitamin C supplements. If you don’t like swallowing pills or want to mix it into beverages, your best bet is to consider liquid or powdered supplements.
Next, you want to check the supplement’s quality. Evaluate whether a brand is reputable by exploring their ingredient sourcing and manufacturing standards. A good product will also be tested by third-party organizations, such as USP, Consumer Labs, or NSF International.
Take a look at added ingredients, too. If you’re trying to limit your intake of added sugars, you want to opt for a supplement that doesn’t contain sugar.
Another factor to consider is the dosage. The recommended daily amount of vitamin C for adults is 90 mg for men, 75 mg for women, and up to 120 mg for women who are pregnant or breastfeeding. However, certain medical conditions may require that you take much higher doses (NIH).
Children have lower vitamin C requirements, which range from 25–75mg per day, depending on their age. However, it’s not generally advised to give children a vitamin C supplement unless their pediatrician has recommended it.
Note that the Tolerable Upper Intake Level (UL) for vitamin C for men, as well as women ages 19 and above, is 2,000 mg. Meanwhile, the UL for children ranges from 400–1,800 mg, depending on age. Daily intakes at or below these amounts are unlikely to result in any adverse health effects (NIH).
Generally, high doses of vitamin C are unnecessary and could contribute to harmful side effects. Only consume high doses if your healthcare provider recommends doing so.
Finally, you want to consider your budget. Some professional-grade brands can be expensive, but keep in mind that a higher price doesn’t necessarily mean a better product. There are plenty of high quality options available at various price points.
First, vitamin C helps encourage the production of white blood cells known as lymphocytes and phagocytes, which help protect the body against infection (PubMed).
Second, vitamin C helps these white blood cells function more effectively while protecting them from damage by potentially harmful molecules, such as free radicals.
Other benefits of Vitamin C
A large review of 29 studies in 11,306 people demonstrated that regularly supplementing with vitamin C at an average dose of 1–2 grams per day reduced the duration of colds by 8% in adults and 14% in children (PubMed).
Interestingly, the review also demonstrated that regularly taking vitamin C supplements reduced common cold occurrence in individuals under high physical stress, including marathon runners and soldiers, by up to 50% (PubMed, PubMed).
A review, published December 7, 2020, in the journal Nutrients, recommended the use of vitamin C as an additional therapy for respiratory infections, sepsis and COVID-19.
In December 16, 2020, Rob Verkerk, Ph.D., founder and scientific director of the Alliance for Natural Health, announced the launch of an international vitamin C campaign in response to the Nutrients review, which “puts all the arguments and science in one, neat place.”
The National Institutes (NIH) Panel has determined that there are insufficient data to recommend either for or against the use of Vitamin C for the treatment of non-critically ill COVID-19 (last updated November 2020).
At the Cleveland Clinic, researchers are enrolling people into a study to see if vitamin C or zinc — or a combination of the two — can reduce the duration of COVID-19 symptoms. Patients will be given the supplements after they have tested positive for COVID-19.
Currently, no definitive evidence supports the use of oral vitamin C supplements to prevent COVID-19.
Vitamin C may help shorten the duration and severity of colds caused by other viruses, but this is no guarantee that it will have the same effect on the coronavirus that causes COVID-19.
Additionally, vitamin C is a water-soluble vitamin. It dissolves in water, meaning that excess amounts aren’t stored in your body but instead eliminated through your urine. Taking more vitamin C does not mean that your body is absorbing more (nih).
High dose vitamin c
High dose vitamin C supplements may even cause diarrhea, as they can signal your body to pull water out of the cells and into your digestive tract (NIH).
Moreover, although high dose vitamin C appears promising for COVID-19 treatment, these doses were exceptionally high and given via IV — not taken orally. Additionally, it was only given in cases severe enough to require hospitalization.
Your best bet is to eat a diet that’s full of a variety of fruits and vegetables, which naturally provide all the vitamin C a healthy person needs — along with many other nutrients and antioxidants.
That said, many vitamin C supplements in the market are above the US RDA. It’s important to seek a doctor’s advice if you intend to take high dose vitamin C on a long term basis. To be on the safe side, you may also request for your kidney functions to be monitored.
