Does fish oil reduce heart rate in humans?
Does fish oil reduce heart rate in humans?
Fish oil consumption reduces heart rate in humans, suggesting a direct or indirect effect on cardiac electrophysiology.
Supports modest heart rate reduction with fish oil; extends observational data but leaves clinical outcome impact open.
In randomized controlled trials in humans, fish oil reduces HR, particularly in those with higher baseline HR or longer treatment duration. These findings provide firm evidence that fish oil consumption directly or indirectly affects cardiac electrophysiology in humans. Potential mechanisms such as effects on the sinus node, ventricular efficiency, or autonomic function deserve further investigation.
