Benefits: Vitamin A is vital for maintaining healthy vision, supporting the immune system, and ensuring proper cell growth and differentiation. It also plays a role in skin health and reproductive functions.
Sources: You can obtain Vitamin A from two main sources:
- Preformed Vitamin A: Found in animal products such as liver, eggs, and dairy products.
- Provitamin A Carotenoids: Found in plant-based foods such as carrots, sweet potatoes, spinach, and kale. The most well-known carotenoid is beta-carotene, which the body converts into Vitamin A.
Recommended Dosage: The Recommended Dietary Allowance (RDA) for Vitamin A varies by age, sex, and life stage. For adults, the RDA is 900 micrograms (mcg) for men and 700 mcg for women.
2. Vitamin C: Boosting Immunity and Skin Health
Benefits: Vitamin C is an antioxidant that helps protect cells from damage caused by free radicals. It is crucial for the synthesis of collagen, which supports skin, blood vessels, and connective tissues. Additionally, Vitamin C enhances the immune system’s ability to fend off infections.
Sources: Rich sources of Vitamin C include:
- Citrus Fruits: Oranges, lemons, and grapefruits.
- Vegetables: Bell peppers, broccoli, and Brussels sprouts.

Recommended Dosage: The RDA for Vitamin C is 90 milligrams (mg) for men and 75 mg for women. Smokers or individuals exposed to higher stress levels may need more.
3. Vitamin D: Vital for Bone Health and Immune Function
Benefits: Vitamin D is essential for calcium absorption, which is crucial for maintaining strong bones and teeth. It also supports the immune system and may play a role in mood regulation.
Sources: Vitamin D can be obtained from:
- Sunlight: The skin produces Vitamin D when exposed to sunlight. However, factors such as geographical location, skin type, and sun protection can affect synthesis.
- Diet: Foods such as fatty fish (salmon, mackerel), fortified dairy products, and egg yolks are good sources.
- Supplements: Vitamin D supplements are often recommended for individuals with limited sun exposure.
Recommended Dosage: The RDA for Vitamin D is 600 IU (International Units) for adults up to 70 years old and 800 IU for those over 70.
4. Vitamin E: An Antioxidant Powerhouse
Benefits: Vitamin E acts as a potent antioxidant, protecting cells from oxidative damage. It also supports immune function and skin health.
Sources: Key sources of Vitamin E include:
- Nuts and Seeds: Almonds, sunflower seeds, and hazelnuts.
- Vegetable Oils: Sunflower oil, safflower oil, and olive oil.
- Leafy Greens: Spinach and Swiss chard.
Recommended Dosage: The RDA for Vitamin E is 15 milligrams (mg) for adults.
5. Vitamin K: Crucial for Blood Clotting and Bone Health
