Vitamins play a crucial role in our body's overall health and wellbeing. They are essential for various bodily functions, including growth and development, maintaining strong bones, and boosting the immune system. Our bodies can’t produce vitamins on their own, so it is important to include a variety of vitamin-rich foods in our diet.
There are 13 essential vitamins, each with its own unique function. The most commonly known vitamins are Vitamin A, Vitamin C, Vitamin D, Vitamin E, Vitamin K, and the B-complex vitamins.
Vitamin A is essential for maintaining good vision, healthy skin, and a strong immune system. The best sources of Vitamin A are carrots, sweet potatoes, pumpkins, and spinach.

Vitamin C, also known as ascorbic acid, is crucial for skin and immune health. Vitamin C is also a powerful antioxidant that helps to protect cells from damage. The best sources of Vitamin C are citrus fruits, berries, kiwi, and bell peppers.
Vitamin D is often referred to as the ‘sunshine vitamin’, as it is produced in our skin when it is exposed to sunlight. Vitamin D is important for maintaining strong bones, as it helps our bodies absorb calcium. The best sources of Vitamin D are fatty fish, eggs, and fortified dairy products.
Vitamin E is a fat-soluble vitamin that helps to protect cells from damage, and it has also been linked to improved heart health. The best sources of Vitamin E are almonds, sunflower seeds, and avocado.

The B-complex vitamins are made up of eight vitamins, each with their own unique function. B vitamins are important for energy production, maintaining a healthy nervous system, and producing red blood cells. The best sources of B vitamins are whole grains, lean meat, poultry, fish, and eggs.
While it is important to include a variety of vitamin-rich foods in our diet, it is also important to know the normal ranges of each vitamin. A deficiency or excess of certain vitamins can lead to health problems.
Vitamin A levels should be between 30-80 µg/dL. Vitamin C levels should be between 0.2-2.0 mg/dL. Vitamin D levels should be between 30-100 ng/mL. Vitamin E levels should be between 7-15 mg/dL.
