Vitamin A Facts You Shouldn’t Sleep On 🥕
This underrated vitamin does more than you think — from protecting your eyes to strengthening your skin and immune system.
👁 Night Vision Fuel
Vitamin A is essential for producing rhodopsin, the protein in your retina that lets you see in low light. Without enough, your ability to see in the dark drops — sometimes leading to night blindness. In fact, vitamin A deficiency is a major cause of preventable blindness worldwide.
🍳 Where to get it?
Eggs, salmon, carrots, sweet potatoes, and kale are all great sources. Animal foods provide preformed vitamin A (retinol), while plants offer beta-carotene — which your body converts to vitamin A. Cooking plant sources boosts absorption.
🛡 Immunity Armor
Vitamin A supports the barrier function of the eyes and gut. It keeps mucosal surfaces healthy and helps immune cells do their job. Without it, your body is more prone to infections — especially in the lungs and digestive tract.
⚠️ Toxic Overload
More isn’t always better. The safe upper limit is 3,000 mcg/day for adults. Going over that — especially through supplements — can cause nausea, dizziness, and even liver damage. Stick to food sources unless advised otherwise.
✨ Skin Fix
Topical vitamin A derivatives, called retinoids, are widely used in skincare for acne and aging. They unclog pores, reduce inflammation, boost collagen, and improve skin texture. Prescription and OTC options vary in strength, but they all trace back to one thing: vitamin A.
If you’re not following, your immune system’s literally squinting.
