☀️ Fat-Soluble Vitamins Overview

Fat-soluble vitamins — A, D, E, K1, K2 — are unique because they require dietary fat for proper absorption. Unlike water-soluble vitamins, they can be stored in the liver and fatty tissues, allowing the body to draw on reserves during times of low intake.

⏳ Deficiencies develop slowly due to storage capacity.
⚠️ Toxicity risk arises with excessive supplementation — balance is essential.
