Study
Grape Seed Extract May Improve Liver Health in Adults with Fatty Liver Disease
Taking grape seed extract supplements was found to improve liver health and metabolic factors in adults with non-alcoholic fatty liver disease.
Summary
In plain language
Researchers found that grape seed extract (GSE) supplements can positively affect liver health in adults with non-alcoholic fatty liver disease (NAFLD). The study involved 50 participants who were divided into two groups: one taking GSE supplements and the other taking a placebo. Over two months, those receiving GSE showed improvements in liver enzymes, blood sugar levels, and blood pressure compared to the placebo group. This finding is significant because NAFLD can lead to serious liver damage and is a growing health concern. Seniors, especially those managing metabolic conditions, might consider discussing GSE supplements with their healthcare provider.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This was a double-blind study where neither the participants nor the researchers knew who was receiving the GSE or placebo. Participants took two tablets daily for two months. Key findings showed potential improvements in liver enzymes and other health markers, indicating GSE might support liver health.
The study was conducted with 50 participants divided into GSE and placebo groups.
Results showed improved liver enzymes and metabolic markers in the GSE group.
While findings are promising, more research is needed to confirm these results.
Seniors interested in GSE should discuss its use with their healthcare providers for personalized advice.
