Strong Support

Giving pigs a cholesterol-lowering drug called atorvastatin for three weeks made their livers produce less of a key protein (apoB) that helps form bad cholesterol particles, without changing how fast those particles were cleared from the blood.

Inhibition of HMG-CoA reductase by atorvastatin decreases both VLDL and LDL apolipoprotein B production in miniature pigs.

Randomized Controlled Trial
Animal
1997 Nov

The study gave pigs a specific dose of atorvastatin for 21 days and found it lowered the amount of a harmful protein (apoB) made by the liver by 34%, and reduced its total amount in the blood by 29%, just like the claim said — and it didn’t change how fast the body cleared it.

Similar Assertions

The same cholesterol drug also made fewer bad cholesterol particles (LDL) in pigs by slowing down how much was made, not by clearing them faster.

The drug lowered several types of bad fats in the pigs’ blood — including total cholesterol, LDL cholesterol, and triglycerides — by up to 31%.

The drug lowered the genetic instructions in the liver for making the bad cholesterol protein, but didn’t change the instructions for clearing it from the blood.

The drug seemed to make less of the bad cholesterol particle by turning fewer big particles into smaller ones, but this effect wasn’t strong enough to be sure it wasn’t just chance.

Atorvastatin doesn’t just lower bad cholesterol — it also lowers overall cholesterol and a key protein linked to heart disease, and higher doses make these effects stronger.
