Strong Support

The liver makes cholesterol using a key enzyme called HMG-CoA reductase, and if we block that enzyme, it lowers the 'bad' cholesterol in your blood.

Reduction of LDL cholesterol by 25% to 60% in patients with primary hypercholesterolemia by atorvastatin, a new HMG-CoA reductase inhibitor.

Randomized Controlled Trial

Human

1995 May

The study tested a drug that blocks a specific enzyme involved in cholesterol production, and it found that this drug greatly lowered bad cholesterol in people. This supports the idea that blocking this enzyme helps reduce cholesterol.

Competitive inhibition of 3‐hydroxy‐3‐methylglutaryl coenzyme a reductase by ML‐236A and ML‐236B fungal metabolites, having hypocholesterolemic activity

Cross-Sectional Study

In Vitro

The study shows that a substance can block the main enzyme the body uses to make cholesterol, which supports the idea that blocking this enzyme helps lower cholesterol.

Untitled Study

A well-designed study shows that a statin drug quickly lowers bad cholesterol in people, which is exactly what the claim is about.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.

Similar Assertions

Inhibition of hepatic HMG-CoA reductase reduces circulating LDL cholesterol by decreasing endogenous cholesterol synthesis and upregulating hepatic LDL receptor expression.

A type of drug that lowers cholesterol works well in lab tests, but high doses can be toxic in animals, which might slow down its use in people.

Blocking a key enzyme in the body's cholesterol factory can lower cholesterol, even in people with a genetic condition that causes high cholesterol. A natural substance called compactin can do this job very effectively.

These two compounds seem to specifically target one key enzyme that makes cholesterol, without messing with the other parts of the process — at least in lab tests.

Blocking the HMGCR enzyme — whether by statin drugs or your genes — makes you about 11–12% more likely to develop type 2 diabetes, and this isn’t because the drugs lower cholesterol.
