Vitamin A — The Vitamin of Vision, Immunity & Inner Glow

If there’s one nutrient that quietly supports almost every corner of your wellbeing — your eyes, your skin, your immunity, even your emotional strength — it’s Vitamin A.

Think of it as the guardian of your inner surfaces. Your eyes, nose, lungs, gut lining, reproductive tract — all depend on it to stay moist, clear, protected, and resilient.

And because it helps your eyes create the pigments needed for dim-light vision, Vitamin A is lovingly called retinol — the nutrient behind clear sight.

But the magic of Vitamin A doesn’t end with your eyes. It strengthens immunity, supports cell repair, guides tissue growth, keeps your skin bright, and nurtures deep internal health. You may not gain superhero night vision, but steady Vitamin A levels will help you see better, heal faster, fight infections more easily, and glow from within.

How Your Body Actually Uses Vitamin A

When you eat Vitamin A–rich foods, your digestive system breaks them down into tiny usable forms — retinol, retinal, and retinoic acid. These active forms then go on to fuel everything from vision and immunity to cell renewal.

Most of the Vitamin A you absorb ends up stored in your liver.
Your liver acts like a wise caretaker, releasing exactly what your body needs, when it needs it.

And here’s something most people don’t know:

Blood tests pick up Vitamin A deficiency only when liver stores are nearly empty.
So “normal” blood levels don’t always mean true nourishment.
Long-term diet, good digestion, and balanced absorption matter far more than a single lab report.

Where Vitamin A Comes From

1. Active Vitamin A (Retinol) from Animal Foods

This is the “ready-to-use” form your body loves. You get it from:

• eggs

• liver

• Fish (salmon, mackerel, herring, tuna, sardines)

• Dairy (milk, curd/yogurt, cheese, butter, ghee)

Your body absorbs this form instantly.

2.Fortified Foods That Contain Retinol

Some foods may be fortified with Vitamin A — meaning Vitamin A is added during processing.
These foods are safe and help increase Vitamin A intake but are not natural sources.

• Fortified milk

• Fortified cereals

• Fortified plant-based milks (soy, almond, oat)

3.Plant sources (provitamin A carotenoids)

• Carrots, pumpkin, sweet potatoes

• Mangoes, papayas

• Spinach, and leafy green leaves

These plant vitamins give you beta-carotene, which your body gently converts into Vitamin A.

Swasti Reminder:

• The deeper the colour, the richer the nourishment.

• Pair colourful vegetables with a little ghee, coconut oil, or olive oil. Fat unlocks Vitamin A.

INFO BOX: What Are Fortified Foods? (Beginner-Friendly Guide)

Fortified foods are regular foods that have extra vitamins or minerals added to them during manufacturing.
The goal is to improve nutrition and prevent common deficiencies in the population.

Think of it as boosting a food’s nutrient profile so people get important vitamins even if their natural diet is low.

Examples of nutrients added during fortification

• Cereals and flour → fortified with B vitamins, folic acid, iron

• Plant-based milks → fortified with Vitamin A, D, and B12

• Milk and edible oils → often fortified with Vitamin A & D

Three Swasti Insights You’ll Always Remember

1. Your Thyroid Helps You Activate Vitamin A

A healthy thyroid helps convert plant pigments (beta-carotene) into usable Vitamin A.
When thyroid function slows, this conversion slows too — even if your diet is colourful.

Support your thyroid with warm meals, steady routines, iodine-rich foods, and calm days.

2. Your Gut Decides How Much Vitamin A You Absorb

Vitamin A absorption depends on your Agni (digestive fire) and your gut microbiome.
Acidity, bloating, irregular meals, constipation, or frequent antibiotics can weaken absorption even when your diet is excellent.

Simple ritual: Sip warm cumin-ginger water after meals to support better uptake.

3. Nature Gives Vitamin A Exactly When You Need It

Ayurveda calls this seasonal intelligence.
Nature naturally provides Vitamin A–rich foods at the right time:

• Summer: Mangoes and papaya to cool the eyes and hydrate the skin

• Winter: Carrots, pumpkin, and leafy greens to strengthen immunity and nourish tissues

Trust the season — your Vitamin A levels will follow.

Why Your Body Loves Vitamin A

Vitamin A plays dozens of roles quietly in the background, but here are the ones you feel most:

Immunity That Works Smoothly

It strengthens your body’s natural defence system, helping you fight infections more effectively.

Healthy Eyes, Even After Long Screen Hours

It helps your eyes adapt to dim light and prevents dryness — something we all need in the digital age.

Soft, Glowing, Resilient Skin

Vitamin A supports the renewal of skin cells and keeps mucus membranes hydrated.

Protection for Your Inner Linings

Your nose, lungs, digestive tract, and reproductive organs rely on Vitamin A to stay strong and well-lubricated.

Cell Growth, Fertility, and Bone Development

It guides cell renewal and supports reproductive health and bone integrity.

It isn’t dramatic.
It isn’t loud.
It simply keeps your inner world working in harmony.

Early Signs Your Vitamin A Is Running Low

Your body whispers before it shouts.
Watch for these gentle signals:

• Dry, itchy, or easily tired eyes

• Difficulty seeing in dim light

• Dull skin or brittle nails

• Frequent colds or throat infections

• Slow wound healing

• Deep, unshakable fatigue

If you notice several of these, your Vitamin A reserves may need support.

A Note on Safety

Because Vitamin A is fat-soluble, excess from supplements can build up in the body.
Be extra cautious if you are:

• pregnant

• taking cod liver oil

• eating liver weekly

• post-menopausal

Plant carotenoids remain the safest source — your body converts only what it needs.

Did You Know? — Gentle Vitamin A Facts Most People Miss

Vitamin A is powerful, and sometimes the way we use everyday products can unknowingly increase our intake. These small insights help you stay balanced:

Cod Liver Oil Isn’t Just Vitamin D

It is also extremely high in Vitamin A.
If you use cod liver oil, make sure your multivitamin does not add extra Vitamin A.

Retinoid Creams Need Night-Time

Retinol-based creams make skin more sun-sensitive.
Apply them at night and avoid strong sunlight the next morning.

Vitamin A in Sunscreens & Lip Balms

Some skincare products contain added retinyl palmitate.
Moderation and label awareness prevent accidental excess.

Vitamin A & D: A Dance of Balance

Too much Vitamin A could interfere with Vitamin D’s ability to support bone health —
They work best when balanced.

Ayurveda’s View — Vitamin A as Rasayana

Ayurveda may not use the word “Vitamin A,” but it recognises its qualities deeply.
Vitamin A–rich foods are considered:

• Chakshushya — supportive of eye clarity

• Rasayana — rejuvenating and immunity-boosting

• Nourishing to Rasa & Rakta Dhatus (plasma and blood)

• Supportive of Ojas — the essence of vitality

Warm meals, ghee, seasonal produce, and mindful eating help Vitamin A settle into your tissues with ease..

Swasti Practical Wisdom

• Add a spoon of ghee to carrot sabzi or saag — absorption improves instantly.

• Follow the 20-20-20 rule for screens: every 20 minutes, look 20 feet away for 20 seconds.

• Trust the season and eat the colours nature offers you.

• Try a weekly Rasayana drink: carrot + beetroot + amla.

• Keep your digestion warm, predictable, and peaceful — Vitamin A depends on Agni.

In Essence

Vitamin A is less about “one nutrient” and more about how you see, how you heal, and how you glow.
Eat colourful foods, pair them with healthy fats, honour your digestion, and follow the season’s wisdom.

Your body already knows what to do —
you’re simply giving it what it needs to thrive.
