one of the guy’s contention is that you need the higher levels of ldl to carry vitamins k,d,a.
So I googled this question: does ldl cholesterol carry vitamin a, vitamin d,and vitamin k on its surface:
No, LDL (Low-Density Lipoprotein) cholesterol does not carry vitamins A, D, or K on its surface. LDL is primarily responsible for transporting cholesterol and other lipids (fats) from the liver to cells throughout the body. Vitamins A, D, and K are fat-soluble vitamins, which means they require fat for absorption and transport in the body, but they do not specifically bind to LDL cholesterol.
Instead, these fat-soluble vitamins are transported in the bloodstream by specialized carriers. For example:
1. Vitamin A: Retinol-binding protein (RBP) is a carrier protein that binds to vitamin A (retinol) and transports it in the bloodstream.
2. Vitamin D: Vitamin D is transported by a protein called vitamin D-binding protein (VDBP) or serum albumin.
3. Vitamin K: Vitamin K is carried by lipoproteins, such as chylomicrons and very low-density lipoproteins (VLDL), rather than LDL.
These carrier proteins and lipoproteins help ensure that fat-soluble vitamins are transported efficiently to their target tissues and organs, where they can be utilized for various physiological processes. LDL primarily carries cholesterol, which is an essential component of cell membranes and is used in the synthesis of hormones and other molecules.

Why don’t you shoot him an email and ask if there is research demonstrating this?
