The Claim
It's commonly believed that L-Carnitine supplements can directly improve heart function and protect against cardiovascular diseases.
Origin
This belief stems from some studies suggesting L-Carnitine's role in reducing heart disease risk factors and its use in clinical settings for specific heart conditions.
What Science Says
While some studies, including meta-analyses, indicate L-Carnitine may help reduce symptoms of angina and improve certain outcomes after heart attacks, its preventive effects on heart disease are not well-established. The benefits are more pronounced in individuals with existing heart conditions rather than in preventing disease onset.
Verdict
Mostly True
