Vitamin A is more than just a nutrient; it’s a vital component of our overall health. It plays a crucial role in supporting our vision, strengthening our immune system, and keeping our skin healthy. This essential vitamin is key to maintaining the health of our organs, tissues, and cells. While it’s commonly linked to animal products, there are plenty of plant-based sources rich in vitamin A. Explore the colourful array of vegan foods high in vitamin A, from bright sweet potatoes to nutritious leafy greens. Embrace the benefits of plant-based nutrition for improved health, a stronger immune system, and radiant skin—all while following a compassionate, animal-friendly lifestyle.
Understanding Vitamin A
Vitamin A comes in two primary forms: preformed vitamin A (retinol), which is found in animal products and provitamin A carotenoids, which are present in plant foods such as sweet potatoes, carrots, and dark leafy greens. These carotenoids, including beta-carotene, alpha-carotene, and beta-cryptoxanthin, are converted into vitamin A by the body. Probiotics can enhance the absorption and utilisation of vitamin A by promoting gut health, aiding in the conversion of carotenoids, and boosting immune function. A well-rounded diet that includes these nutrients supports healthy vision, immune function, and skin health, ultimately contributing to overall well-being.

Why Does Vitamin A Matter for Vegans?
Vitamin A is essential for overall health, offering specific benefits for vision, immunity, and skin health.
Vision Health:
- Vitamin A is vital for regenerating rhodopsin, a protein in the retina that aids low-light vision.
- A deficiency can lead to night blindness, making it hard to see in low light.
- Severe deficiencies may result in xerophthalmia, a condition characterised by dry, irritated eyes.
Immune Function:
- Vitamin A is important for the health of immune cells, including natural killer cells and T-cells.
- It plays a role in regulating inflammation and oxidative stress.
- Maintaining adequate levels of vitamin A can lower the risk of infections, especially respiratory and gastrointestinal ones.
Skin Health:
- Vitamin A helps maintain skin integrity, preventing dryness and irritation.
- It supports collagen production, which can reduce fine lines and wrinkles.
- The antioxidant properties of vitamin A help protect the skin from damage caused by UV radiation.
Additional Benefits:
- Vitamin A is important for reproductive health and foetal development during pregnancy.
- It also helps regulate gene expression and cell growth.
The recommended daily intake of vitamin A varies based on age, sex, and life stage, with a general recommendation of 700-900 μg (micrograms) per day.
Tips for Maximising Vitamin A Intake:
- Incorporate a variety of colourful fruits and vegetables into your diet
- Opt for organic or locally sourced produce whenever possible
- Store fruits and vegetables correctly to maintain their nutrients
- Lightly cook vegetables to help preserve their nutritional value
- Consider seeking advice from a registered dietitian for tailored recommendations
Conversion Factors:
- Beta-carotene: 12-24 μg = 1 μg vitamin A
- Alpha-carotene: 24 μg = 1 μg vitamin A
- Beta-cryptoxanthin: 12 μg = 1 μg vitamin A
Note: Lutein and zeaxanthin do not convert directly to vitamin A but offer their own unique benefits, especially for eye health. The recommended daily intake for these carotenoids varies:
Lutein: 10-20 mg/day Zeaxanthin: 2-4 mg/day
1. Beta-Carotene: This precursor to vitamin A is converted in the body to support:
- Vision health
- Immune function
- Skin health
- Antioxidant defences
2. Alpha-Carotene: Similar to beta-carotene, it supports:
- Vision health
- Immune function
- Skin health
- Antioxidant defences
3. Beta-Cryptoxanthin: A carotenoid with antioxidant properties that supports:
- Immune function
- Skin health
- Anti-inflammatory responses
4. Lutein and Zeaxanthin: These carotenoids support:
- Eye health (reducing the risk of macular degeneration)
- Vision clarity
- Antioxidant defences
- Filtering blue light
Understanding these conversion factors is essential for ensuring you get enough vitamin A from plant-based sources.
Sweet Potatoes
Sweet potatoes are a fantastic source of vitamin A. A medium sweet potato offers more than 100% of the daily recommended intake of vitamin A (1,046 μg). They are rich in various carotenoids, such as beta-carotene, alpha-carotene, and beta-cryptoxanthin.
Additional Nutritional Benefits:
- Fibre: promotes digestive health and helps you feel full
- Vitamin C: boosts immunity and supports collagen production
- Potassium: contributes to heart health and muscle function
- Antioxidants: help fight oxidative stress and inflammation
Preparation Tips:
- Bake or roast sweet potatoes to keep their nutrients intact

Optimization of Vitamin A by Healthy Fats
Healthy fats increase the absorption of vitamin A, meaning that all vitamin A absorbed from the gut would be used. Incorporating probiotic-rich foods like yoghurt, kefir, kimchi, and sauerkraut alongside provitamin A-rich foods can optimise vitamin A absorption.
Benefits of Healthy Fats
- Increase the absorption of vitamin A by 50%
- Support immune function and reduce inflammation
- Maintain healthy skin growth, hair, and nail production.
- Help in the absorption of fat-soluble vitamins (A, D, E, K)
Sources of Healthy Fats:
- Avocado
- Nuts: almonds and walnuts
- Seeds: chia and flax
- Olive oil
Tips for Optimal Absorption :
- Add healthy fats to vitamin A-rich foods
- Use olive oil for cooking and dressing salads
- Snack on nuts and seeds
- Add avocado to smoothies and salads.
Key Compounds
- Monounsaturated fats (avocado, olive oil)
- Polyunsaturated fats (nuts, seeds)
- Omega-3 fatty acids (walnuts)
Combine healthy fats with vitamin A-rich foods to maximise the absorption and benefits for overall health improvement.
Getting Adequate Vitamin A from a Vegan Diet
A well-planned vegan diet easily delivers enough vitamin A for optimal health and wellness, laying to rest any misconception that vitamin A deficiency goes along with plant-based eating. The honest truth is that a thoughtful and diverse vegan diet can furnish all the vitamin A the body needs from many whole, plant-based foods. Sweet potatoes, carrots, dark leafy greens, and colourful fruits such as mangoes and papayas are good sources of beta-carotene, alpha-carotene, and beta-cryptoxanthin that become vitamin A within the body. Many plant-based milk and cereals are fortified with vitamin A. Vitamin A-rich foods also can be consumed in conjunction with healthy fats like avocado or nuts to make better absorption. A vegan diet, without proper planning and paying attention to nutrient-rich foods, can supply all the vitamin A needed for healthy vision, proper functioning of the immune system, and for radiant skin, which has contributed much to the myth of vitamin A deficiency in plant-based eating. A well-planned vegan diet truly holds the pathway to vibrant health and wellness.
Conclusion
Vitamin A is a very important nutrient necessary for optimal health and wellness. A well-planned diet with whole foods, like sweet potatoes, carrots, and dark leafy greens, and fruits such as mangoes and papayas, is rich in vitamin A. Knowledge of key compounds, such as beta-carotene, alpha-carotene and beta-cryptoxanthin optimises use. Healthy fats can be added, fortified plant-based milk and cereals chosen, and supplements taken (if necessary) to supplement vitamin A intake. Plant-based sources alone are adequate for a balanced vegan diet. Vitamin A maintains healthy vision, a healthy immune system, and healthy skin, all which provide many benefits for the reduction of chronic diseases. For specific recommendations, one should consult a healthcare provider or registered dietitian. Focus on whole foods, judicious supplementation, and make informed decisions to maximise the benefits that vitamin A provides for overall well-being.
