Fat-Soluble Vitamins: Why You Need Fat to Absorb Them

Not all vitamins are created equal. Some dissolve in water (like Vitamin C), and your body flushes out the excess. Others dissolve in fat—and without enough dietary fat, you can't absorb them at all.

At Better Health Beat, we emphasize the importance of eating fat with your vitamins. Here's why.

The Fat-Soluble Four

There are four fat-soluble vitamins: A, D, E, and K. They're stored in your liver and fatty tissues, which means you don't need to consume them every single day—but chronic deficiency has serious consequences.

Vitamin A (Retinol)

Essential for vision, immune function, and skin health. Found in liver, egg yolks, and butter. Note: Beta-carotene (from carrots) is a precursor, but the conversion is inefficient—true Vitamin A comes from animal sources.

Vitamin D (Calciferol)

The 'sunshine vitamin' is actually a hormone. It regulates calcium, supports immunity, and influences over 1,000 genes. Most people are deficient.

Vitamin E (Tocopherol)

A powerful antioxidant that protects cell membranes from oxidative damage. Found in nuts, seeds, and olive oil.

Vitamin K (Phylloquinone & Menaquinone)

K1 (from greens) helps with blood clotting. K2 (from fermented foods and grass-fed butter) directs calcium into bones and teeth—and out of arteries.

The Absorption Hack

Always take fat-soluble vitamins with a meal that contains fat. A salad with olive oil, avocado with your eggs, or a spoonful of coconut oil will do the trick.
