Vitamin A (Retinol & Beta-Carotene)
Vitamin A supports healthy vision, strong mucous membranes, and the body’s ability to maintain balanced inflammation. Retinol is the active form of vitamin A and is stored primarily in the liver, while beta-carotene is a plant-based precursor stored in fatty tissues. Retinol is found in foods such as liver, egg yolks, dairy fats, and fish liver oils. Beta-carotene is abundant in colorful vegetables like carrots, sweet potatoes, and leafy greens including spinach, cabbage, lettuce, and broccoli.
Retinol and beta-carotene differ in their activity and safety profile. Retinol is already an active vitamin A form the body can use immediately, while beta-carotene must first be converted into vitamin A. Beta-carotene is naturally safe and does not carry toxicity concerns, even at higher amounts, because the body only converts what it needs. Cooking vegetables improves the absorption of beta-carotene, and healthy fats enhance the use of both forms in the body. Vitamin A is also influenced by other nutrients—zinc may lower its stores, while vitamins C and E help stabilize and protect it. This vitamin may be especially helpful for supporting resilience in cases of digestive stress, chronic inflammation, or reduced absorption.
