Why I Take Over 100 Supplements a Day - today: AVITAMIN A
Posted by Eric Walter on 13.02.25
Hello, my friends and customers! As many of you know, my mission is to stay healthy, active, and mobile for the rest of my life, about 125...just as I have been over the past ten years. Every day on this blog, I’ll share insights into the 100+ supplements I take, explaining how they support my longevity goals.
Today, let’s talk about Vitamin A.
Why Vitamin A Matters
It might not be the flashiest nutrient, but it is vital for vision, immunity, and skin health. It is a cornerstone of my daily protocol for maintaining cellular function and sharp eyesight.
What is Vitamin A?
It refers to a group of fat-soluble nutrients:
-
Retinoids: Pre-formed Vitamin A found in animal foods (liver, eggs).
-
Carotenoids: Plant-based precursors (like beta-carotene in carrots) that the body converts into Vitamin A as needed.
Key Benefits
-
Eye Health: Essential for night vision. Personally, I use it as part of my strategy to maintain and improve my eyesight.
-
Immune Defense: It maintains the health of your "first line of defense"—the skin and mucosal linings of the nose and throat.
-
Cellular Repair: Vitamin A supports skin regeneration and helps cells function correctly, which aids in anti-aging.
Sources and Timing
While found in liver, eggs, and leafy greens, I supplement with fish liver oil (3000mcg / 10,000 IU).
Best Practice: Since Vitamin A is fat-soluble, it is best absorbed when taken with fat. Although I take it after my only meal of the day in the afternoon, containing healthy fats.
