Study
Aged Garlic Extract May Help Lower Blood Pressure in Seniors With Hypertension
Daily intake of aged garlic extract reduced systolic blood pressure by 1.8 mmHg in older adults with hypertension.
Summary
In plain language
Recent research has shown that a daily supplement of aged garlic extract can help lower blood pressure in seniors with Grade I hypertension who are already taking medication. In the study, participants taking the garlic supplement saw a reduction in their systolic blood pressure by an average of 1.8 mmHg after 12 weeks. This finding is significant because managing blood pressure is crucial for reducing the risk of heart disease and stroke, especially in older adults. The study suggests that aged garlic could be an effective natural addition to existing treatments for seniors looking to control their blood pressure better.
Details
Use the full description to understand the study design, methods, and the limits of the findings.
This study was a rigorous, triple-blind trial where participants with Grade I hypertension were randomly assigned to take either a garlic supplement or a placebo for 12 weeks. Researchers found that those taking the garlic supplement experienced a small but significant reduction in blood pressure.
The study was carefully designed to measure the effects of aged garlic extract on blood pressure in seniors already on medication.
Participants taking the garlic supplement saw a reduction in systolic blood pressure by 1.8 mmHg and diastolic blood pressure by 1.5 mmHg.
While promising, the study notes that garlic should be used in conjunction with, not as a replacement for, prescribed medications.
Seniors interested in trying aged garlic should discuss it with their healthcare provider to ensure it fits into their overall treatment plan.
