The Claim
Acute oral antioxidant supplementation before exercise training has no effect on resting blood pressure or flow-mediated dilation in elderly men with mild hypertension.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In elderly men with mild high blood pressure, taking antioxidant supplements before exercise does not change their resting blood pressure or the ability of their blood vessels to widen in response to increased blood flow.
See the scientific wording
In six elderly men with mild hypertension, acute oral antioxidant supplementation before exercise training had no effect on resting blood pressure or flow-mediated dilation, indicating that antioxidants alone do not improve vascular function in this population.
When the body exercises, it produces small amounts of reactive molecules that signal blood vessels to relax and improve blood flow. Antioxidants in the bloodstream remove these signaling molecules before they can activate the enzyme that makes nitric oxide. Without nitric oxide, blood vessels stay constricted, and blood pressure does not drop.
What the research says
1 studyIn six older men with high blood pressure, taking antioxidant pills by themselves didn't lower their blood pressure or help their arteries work better. The study confirms that antioxidants alone don't fix these problems.
