10 Best Vitamin C Tablets 2021

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 (PubMed, PubMed).

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).

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 (PubMed, PubMed).

I started using Ester-C 1000 mg last year. Throughout last winter I was repeatedly exposed to the flu and pneumonia in my work office, and my immune system stayed strong. The worst I had was a sniffle for a couple days and that was it. My husband and my son also take this product and they have not been sick either. I just purchased four more bottles and I will use it throughout this whole winter again. I take up to 7,000 mg a day when people around me are sick in my office; My husband and my son do the same thing. I am 5 ft tall 150 lbs. I have used other types of vitamin c in the past but I never had the positive results I had with Esther c.

I don’t take vitamins or hardly any pills. However, when I started getting sick with sinus stuff, I tried these. I chewed one in the morning and one at night. It stopped the sickness in its tracks! Whereas usually it goes into a sinus infection for me, I was better in 2-3 days. I now tell everyone about these.
