L-arginine
- On/off pattern
- No validated on/off cycle exists for general workout or cardiovascular use.
- Duration & evidence
- A trained-cyclist study lasted 28 days without an endurance advantage. This is a research duration, not a recommended 28-day course.
- When to review
- Review cardiovascular history and interacting medicines before considering use; a recent heart attack requires the treating team’s advice.
- A post-heart-attack trial was stopped after more deaths in the arginine group. A shorter course or planned break does not establish safety.
- Nitric-oxide biology does not establish that routine use benefits the heart or that a pump signals useful training adaptation.
