Vitamin C

Humans, unlike most animals, cannot synthesize Vitamin C, so it must be obtained through diet or supplements. Here's how Vitamin C functions and contributes to health:

1. Immune System Support: Vitamin C is widely recognized for its role in boosting the immune system. It supports the production and function of white blood cells, which are key to fighting infections. It also helps these cells work more effectively, protects them from damage by potentially harmful molecules, such as free radicals, and supports the skin’s defense system.
2. Antioxidant Properties: Vitamin C is a strong antioxidant that can neutralize free radicals in the body. This helps reduce oxidative stress and lower the risk of chronic diseases like heart disease and certain cancers.
3. Collagen Synthesis: Vitamin C is essential for the synthesis of collagen, a protein that is a key component of connective tissues in the body. This is important for the health and repair of tissues in various parts of the body, including the skin, bones, and blood vessels, and aids in wound healing.
4. Skin Health: Due to its role in collagen production and its antioxidant properties, Vitamin C is beneficial for the skin. It can help delay the signs of aging, reduce wrinkles, and promote a healthy skin complexion.
5. Absorption of Iron: Vitamin C improves the absorption of iron from the diet. It converts iron that is poorly absorbed, such as plant-based iron sources, into a form that is easier to absorb. This is especially important for individuals prone to iron-deficiency anemia.
6. Cardiovascular Health: Some studies suggest that Vitamin C may help lower blood pressure in both those with and without high blood pressure. An adequate intake of Vitamin C through diet or supplements could positively impact heart health.
7. Brain Health: Vitamin C plays a key role in brain health and cognition. It is necessary for the synthesis of certain neurotransmitters and can protect against age-related mental decline and Alzheimer's disease due to its antioxidant properties.
8. Reduced Chronic Disease Risk: The antioxidant properties of Vitamin C can reduce inflammation and lower the risk of developing chronic diseases, including certain types of cancer, heart disease, and cataracts.
