8 min read

If you’re like most people, you’ve probably tried at least one (if not all) of the over-the-counter immunity supplements on the market. But did you know that the best immune system boosters are the foods your body naturally craves?

Vitamins are organic substances that our bodies need for good health. They are responsible for many of the essential functions of the body, including strengthening cell walls. Dietary sources of vitamins include fresh fruits, vegetables, cereals, and dairy products. Occasionally, however, it may not be possible to get all the vitamins you require from food, mainly if you eat poorly. Vitamin supplements may be a better option.

Why Do You Need Vitamin C?

The role is of Vitamin C is significant to our bodies. The reason for this is that this vitamin has several health benefits. These include:

  1. Providing energy to our muscles
  2. Protecting us against infections and diseases 
  3. Helping with wound healing
  4. Assisting with the formation of collagen
  5. Supporting the function of the heart and lungs
  6. Promoting strong bones
  7. Improving our ability to absorb iron
  8. Maintaining healthy gums
  9. Assisting with the absorption of calcium
  10. Increasing mental alertness

Vitamin C can prevent or treat respiratory infections. Citrus fruits such as oranges and lemons contain the vitamin. You can also take it as a supplement.

How Does Vitamin C Work?

Vitamin C is a water-soluble essential nutrient that is present in both plants and animals. Humans store vitamin C in their livers and kidneys. When we eat foods containing vitamin C, the body absorbs the vitamin into its bloodstream. When we take vitamin C supplements, the body does not store the vitamin; instead, it directly uses it. Therefore, taking vitamin C supplements is more effective than consuming foods rich in vitamin C.

People who want better health but don’t know why they’re unwell use supplements. Some examples are:

Antibiotics – antibiotics kill bacteria, but they do not necessarily destroy viruses. Antiviral medications are available to help prevent viral infections.

Anemia – Iron deficiency is common among women who are pregnant or menstruating. Taking vitamin C along with other nutrients will increase the number of red blood cells in the body.
