Vitamin A is a vital nutrient that plays a key role in maintaining overall health, supporting vision, immune function, skin health, and more. As a fat-soluble vitamin, vitamin A exists in two main forms: retinoids (found in animal products) and carotenoids (found in plant-based foods). Retinoids are readily usable by the body, while carotenoids must be converted into the active form of vitamin A.

Given its essential functions, maintaining adequate vitamin A levels is crucial for both adults and children. A deficiency in vitamin A can lead to significant health problems, underscoring the importance of including vitamin A-rich foods in one’s diet. This article explores the various sources of vitamin A, recommended intake, health benefits, and how to prevent deficiency.

What is Vitamin A?

Vitamin A is essential for several physiological processes. It is found in animal-based foods such as retinol and in plant-based foods as beta-carotene, which the body converts to vitamin A. Recommended daily intake levels differ based on age and gender. Adult men require approximately 900 micrograms (mcg) of vitamin A daily, while adult women need about 700 mcg. Pregnant and breastfeeding women generally require higher amounts to support foetal and infant development.

Role of Vitamin A in Health

Vitamin A is associated with various health benefits, from antioxidant protection to immunity. Below are some of its primary roles:

1. Antioxidant Protection: As an antioxidant, vitamin A helps prevent cellular damage from free radicals, which can lead to chronic diseases and ageing.

2. Immunity: Vitamin A is crucial for maintaining immune function, and enhancing the body’s response to infections.

3. Eye Health: Known for promoting good vision, vitamin A helps prevent night blindness and age-related vision problems.

4. Skin Health: Vitamin A supports skin health by promoting cell growth, reducing wrinkles, and addressing acne concerns.

5. Organ Functioning: It aids in the proper functioning of the heart, lungs, and kidneys.

6. Reproductive Health: Vitamin A plays a role in reproductive health and foetal development, making it essential for pregnant women.

7. Foetal Development: It is critical for foetal tissue and organ development during pregnancy.

8. Teeth and Gums: It contributes to healthy teeth and gums, supporting oral health.

Fruits High in Vitamin A

Certain fruits, especially those with orange or yellow pigmentation, are rich in beta-carotene and contribute to daily vitamin A intake.

Signs of Vitamin A Deficiency and Toxicity

Vitamin A deficiency is relatively common and can lead to symptoms like night blindness, dry skin, poor immune response, and growth delays in children. Severe vitamin A deficiency can cause complete blindness and increase the risk of infections. Here are a few signs and symptoms of vitamin A deficiency:-

    1)   Irregular white deposits in eyes

    2)   Delayed Growth (in children)

    3)   Infertility

    4)   Infections

    5)   Night Blindness

    6)   Lack of quick healing of wounds

If these signs are observed it is recommended to take the required tests and get medications from a doctor.

On the other hand, excess vitamin A, primarily from supplements, can lead to toxicity. Symptoms include dizziness, nausea, and even liver damage in severe cases. It’s essential to balance vitamin A intake and avoid excessive supplementation.

Conclusion

Vitamin A is essential for overall health, supporting skin, vision, immune function, and reproductive health. By incorporating a variety of vitamin A sources—such as liver, dairy, carrots, and leafy greens—one can easily meet daily requirements and enjoy a balanced diet. To safeguard long-term health, consider monitoring your diet and explore a health insurance policy that promotes regular health check-ups and preventive care.

Frequently Asked Questions

    1)   How can I increase my vitamin A?

To boost vitamin A intake, incorporate foods rich in both retinoids (from animal products) and carotenoids (from plants) into your diet. Add liver, dairy, carrots, and leafy greens to your meals regularly.

    2)  How do you increase vitamin A absorption?

Since vitamin A is fat-soluble, pairing it with healthy fats (such as olive oil or avocado) can enhance absorption. This helps the body more effectively utilise the nutrient.

    3)  What are the symptoms of low vitamin A?

Signs of vitamin A deficiency include night blindness, dry skin, increased risk of infections, and, in severe cases, complete blindness. Other symptoms may include delayed growth in children and poor wound healing.
