8 Best Vitamin C Tablets 2022

Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin that is required for all body tissue growth, development, and repair. Vitamin C is also an antioxidant that defends your cells against the effects of free radicals. Free radicals are unstable atoms that can damage cells and are linked to diseases, for instance; heart disease, cancer.


Skin health

Remembering that Vitamin C has an important role in collagen formation, Vitamin C may help to heal damaged skin, as well as keeping it nourished and healthy. Moreover Vitamin C is important for antioxidant protection which help to give skin protection against oxidative damage produced by free radicals, UV, and pollution.


Anti-inflammatory effect

In hypertensive and/or diabetic obese patients, vitamin C (500 mg twice daily) has the ability to reduce inflammatory status by lowering hs-CRP, IL-6, and FBG. [Trusted Source]


Boost Immunity
One of the main reasons people take vitamin C supplements is to boost their immunity, as vitamin C is involved in many parts of the immune system.  
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 review of 28 studies (Diabetes Care. 2021 Feb) in 1,574 people with type 2 diabetes mellitus, demonstrated that vitamin C supplementation may improve blood sugar control and blood pressure in people with type 2 diabetes.


People who have pneumonia tend to have lower vitamin C levels, and vitamin C supplements have been shown to shorten the recovery time (PubMedPubMed).

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% (PubMedPubMed).


Additionally, high dose intravenous vitamin C treatment has been shown to significantly improve symptoms in people with severe infections, including sepsis and acute respiratory distress syndrome (ARDS) resulting from viral infections (PubMedPubMed).

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.


Although 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).Trusted Source

Consuming high doses of vitamin C for prolonged periods may also increase your risk of kidney stones (NIH).

Always consult your healthcare provider prior to adding any nutritional supplement to your routine.

The recommended daily dose of vitamin C for adults is 65 to 90 milligrams (mg), with a maximum of 2,000 mg per day.

Vitamin C is an essential nutrient. It supports many cellular operations of your body’s adaptive immune systems, which contributes to your immune defense system. As an antioxidant, it can help the body combat free radicals, reducing inflammation and increasing immunity.
