Red Yeast Rice May Help Lower Bad Cholesterol in Seniors
Red yeast rice extract significantly reduced total and LDL cholesterol without major side effects in people with high cholesterol.
Summary
In plain language
Research has shown that red yeast rice extract can be effective in reducing high cholesterol levels, particularly the 'bad' LDL cholesterol, in adults. This study reviewed several clinical trials and found a significant decrease in total cholesterol by an average of 37 mg/dL and LDL cholesterol by 36 mg/dL among participants using the extract. Importantly, the supplement also appeared to be safe, with no serious side effects reported for most individuals. These findings suggest that red yeast rice might be a helpful alternative or complement to traditional cholesterol-lowering medications, like statins, especially for seniors concerned about medication side effects.

Use the full description to understand the study design, methods, and the limits of the findings.
This study conducted a systematic review and meta-analysis, which means it combined results from 14 different clinical trials. Researchers focused on the effects of red yeast rice extract on cholesterol levels in people with high cholesterol. Most studies included had participants take the extract for 4 to 24 weeks.
The review found a significant reduction in total and LDL ('bad') cholesterol levels, with no increase in life-threatening side effects.
This suggests red yeast rice could be an effective alternative for those unable to tolerate statins.
However, the study noted the need for more research to confirm long-term benefits and safety.
Discussing this supplement with a healthcare provider can help determine if it's a suitable option.
