Safety and efficacy of very low LDL-cholesterol intensive lowering: a meta-analysis and meta-regression of randomized trials.

Surprising Findings
Very low LDL-C (<40 mg/dL) showed no increased risk of any of the 8 major non-cardiovascular safety outcomes studied.
Common medical wisdom warned that pushing LDL this low might trigger cancer, brain issues, or muscle damage—this study found zero evidence of that.
Practical Takeaways
If you're on high-intensity statins or PCSK9 inhibitors and your LDL is below 40 mg/dL, don't panic—this study suggests you're not at higher risk for cancer, stroke, or cognitive decline.

Keeping your 'bad' cholesterol really low—below 55 mg/dL—might give your heart and blood vessels the best protection against clogged arteries and heart problems.
People who take strong cholesterol-lowering drugs to get their LDL very low don’t stop taking them more often because of side effects than those on regular doses.
When people lower their 'bad' cholesterol to very low levels using strong medications, they have fewer heart attacks and strokes than those with higher cholesterol levels.
Getting cholesterol extremely low doesn’t seem to make people more likely to get cancer, stroke, diabetes, liver problems, muscle issues, or cataracts — at least not in the time frame studied.
Taking strong cholesterol drugs to get LDL very low doesn’t make you more likely to develop type 2 diabetes than taking standard doses.
