Vitamin C

Vitamin C is a powerful antioxidant that plays a vital role in immune function and disease prevention. It helps protect our cells from damage, supports collagen production, and aids in the absorption of iron. Including vitamin C-rich foods such as citrus fruits, berries, and leafy green vegetables in your diet can help boost your immune system and reduce the risk of chronic diseases.

B Vitamins

B vitamins are a group of vitamins that play a crucial role in energy metabolism, brain function, and the production of red blood cells. They include folate, thiamine, riboflavin, niacin, vitamin B6, vitamin B12, biotin, and pantothenic acid. B vitamins are essential for maintaining a healthy nervous system, supporting cognitive function, and preventing conditions like anemia and birth defects.

Folate

Folate, also known as vitamin B9, is especially important for women of childbearing age. It helps in the development of the neural tube in embryos and can prevent certain birth defects. It is also essential for the production of DNA and red blood cells.
