Best Vitamins C Supplements for Strong Immune System

Vitamin C stands out among the rest of the nutrients in food for its effectiveness in strengthening the immune system, while reducing fatigue, regulating metabolism, and promoting collagen production. Currently, there is a wide variety of vitamin C supplements on the market, so we will detail some of the most prominent, such as Zenement 240 Tablets, which contributes to the proper functioning of the nervous system and has enough quantity to provide 8 months of treatment. Another outstanding option is Rite-Flex Rose Hips, which has a dose of 1000 mg per tablet and is suitable for vegans.

However, not all supplements of this nutrient have the same utility, so we have created a list with the best vitamins C of 2020, where you can find detailed information on the most relevant models.


The dosage is the amount in mg of vitamin C that you can find in each pill, but this should be according to your age. According to experts, babies should consume 50 mg per day, children up to 8 years only 25 mg, and adults from 19 years between 45 and 90 mg, but these are only recommended amounts to avoid suffering from vitamin deficiency C, in general, we consume more vitamins on a daily basis if we have a balanced diet full of fruits and vegetables.

We can find supplements with a dosage from 162 mg to 1000 mg of vitamin C, the latter being the most common among the different presentations, with daily consumption of a single pill. In this sense, most manufacturers put the recommended dose and how to consume it on the label, which makes it easier to use. On the other hand, it is necessary to know that it is not very common to exceed the consumption of vitamin C, taking into account that the healthy limit according to experts is 2000 mg.


Among its main ingredients, we can find those that are rich in vitamin C and are the ones that make up most of its composition. A good and inexpensive vitamin C is usually made up of elements of plant and natural origin, which ensures that they are suitable for all people.

Among the most popular options, we can find vitamin C that are composed of citrus bioflavonoids, made up of non-nitrogenous plant substances that are present in most citrus fruits. These help to strengthen the walls of the blood vessels and promote the absorption of nutrients.

Another ingredient that we can find in a vitamin C capsule is rosehip oil, which acts as a powerful collagen stimulator and serves as a powerful regenerator for the skin, since it is made up of essential acids, such as vitamin A, omega 3, and antioxidants.

Acerola cherry is one of the richest fruits in vitamin C and one of the most common ingredients in supplements. This ingredient contains 695 to 4827 mg of vitamin C per 100 g of fruit, which far exceeds the vitamin C content of oranges, grapefruits and lemons, which are normally associated with this vitamin. Consequently, it helps prevent degenerative diseases, such as cancer and others associated with the heart.
