Recommended Vitamin C Brand - 12 Best Vitamin C Supplements (2022) to Fight Against the Flu Virus
As of April 2022, there are more than 40 studies that have been published to investigate the benefits of vitamin C against COVID-19. Check out the evidence tracker on vitamin C and COVID-19 from c19vitaminc.com (constantly updated).
Benefits of vitamin CVitamin C plays an essential role in the body. Thanks to its antioxidant properties, it has been found to have several benefits, particularly for skin and immune health.
Found concentrated in the skin, vitamin C boosts collagen production and helps protect from UV damage (Trusted Source).
The most commonly known benefit of vitamin C, though, is for immune health, particularly as it relates to the common cold.
Some research has found that supplementing with vitamin C can shorten the duration of a cold and may help prevent and treat other infections, such as tetanus and pneumonia. But more human studies are needed (Trusted Source).
Additionally, a systematic review found that vitamin C supplementation was effective in lowering blood pressure in people with hypertension (Trusted Source).
Preliminary research also suggests that vitamin C has anticancer properties and that a high dose supplement could potentially be used as an alternative treatment in people with cancer (Trusted Source, Trusted Source, Trusted Source).
Other research has been investigating the use of vitamin C supplementation in people with stress-related disorders, such as depression and anxiety, because it has been shown to help improve mood. However, more research is still needed overall (Trusted Source).
How to choose a Vitamin C SupplementSelecting the right vitamin C supplement depends on a variety of factors, including the form, quality, dose, and price. There are many forms of vitamin C available (ascorbic acid, sodium ascorbate, calcium ascorbate, liposomal vitamin C etc.) but there is not much evidence that one form is much better than another.
You can also 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).Vitamin C supplements come in a wide range of dosage options. If you’re looking for a high dose, it may be more economical and convenient to find a concentrated supplement. This way you won’t be stuck consuming multiple servings of a lower dose option.
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.

Can Vitamin C help against the Coronavirus?
Safety: The U.S. Recommended Dietary Allowance (RDA) for vitamin C is 75 to 120 milligrams per day. Taking large doses of vitamin C (ascorbic acid) on a regular basis lowers your level of copper, so if you are already deficient in copper and take high doses of vitamin C, you can compromise your immune system.
Temporarily taking megadoses of vitamin C supplements to combat a case of the cold or flu is likely not going to cause a problem.
Moreover, although high dose vitamin C appears promising for COVID-19 treatment, these doses were exceptionally high and given via IV (intra-venous) — not taken orally. Additionally, it was only given in cases severe enough to require hospitalization. Therefore, please do not try these dosages without medical supervision.
Possible side effectsAlthough vitamin C is a natural compound, getting too much of it can cause uncomfortable and potentially serious side effects.
Some of the most common reported side effects include headaches, flushed skin, nausea, and vomiting (NIH). Consuming high doses of vitamin C for prolonged periods may also increase your risk of kidney stones (NIH).
So should you just focus on Vitamin C alone or should you consider other supplements? Vitamin C alone might not be enough as an optimal strategy. A combination and a synergistic mix of supplements would be better.
