1. Vitamin C

Vitamin C, also known as ascorbic acid, is an essential nutrient that plays numerous important roles in the body. Perhaps its most well-known function is as a powerful antioxidant, which helps supportcells against free radicals. [1]

In addition to its antioxidant properties, vitamin C is also essential for supporting the immune system. Specifically, it helps stimulate the production and activity of white blood cells, which are responsible for fighting off infections and other foreign invaders. This is why vitamin C is often recommended fort the immune system, particularly during cold and flu season.

While it's ideal to obtain vitamin C from food sources, such as citrus fruits, strawberries, kiwi, and cruciferous vegetables like broccoli and Brussels sprouts, many people may not consume enough of these foods regularly. In these cases, some people may opt for vitamin C supplements which can provide a convenient and effective way to boost intake.

2. Vitamin D

Vitamin D is a vital nutrient that the human body requires to maintain healthy bones and teeth, support normal muscle function, and regulate calcium and phosphorus levels in the blood. Vitamin D helps regulate the immune response by activating and regulating various immune cells. It is said to help the body to produce antimicrobial peptides, which are natural antibiotics that can fight off invading bacteria and viruses [2]

While the body can produce vitamin D through exposure to sunlight, many people do not get enough vitamin D from this source, especially during the winter months when sunlight is limited. Factors such as age, skin color, and the use of sunscreen can also affect the body's ability to produce vitamin D. For this reason, many people may opt to take vitamin D supplements to maintain adequate levels of this essential nutrient.
