Frequently Asked Questions
Frequently Asked Questions
What does Nitric Oxide™ do?
Our plant-based formula is designed to naturally support healthy circulation, boost energy, and enhance performance. It works by increasing your body’s own nitric oxide levels—known to improve blood flow and cardiovascular function—without stimulants or synthetics.
When should I use it?
Take two capsules daily:
In the morning for all-day energy and endurance
Before workouts to improve blood flow and stamina
As part of your heart-health or wellness routine
Each dose is designed to support natural nitric oxide production throughout the day.
Will it make me jittery?
Not at all. Nitric Oxide™ is 100% stimulant-free. It boosts performance and circulation without causing crashes, jitters, or restlessness.
Is it habit-forming?
Nope! Nitric Oxide™ is non-addictive, drug-free, and safe for daily use—powered only by clean, plant-based ingredients.
What makes Nitric Oxide™ different?
We use a science-backed blend of fermented beet nitrates, potassium, and vegan-friendly ingredients—delivered in easy-to-take capsules. No chemicals, no fillers, no nonsense.
Is there a guarantee?
