Was previously using beet root as a nitric oxide supplement but I find that the L-Arginine is more effective.

Been taking this for about six weeks. Energy is more consistent and I feel less sluggish in the afternoons. Happy with the purchase.

Third-party tested, clean label. That's what I look for first. Actually works too, which is a bonus.

Works well. Deducting a star because the bottle is hard to open with one hand, but the product itself is solid.

Switched from a more expensive brand and honestly can't tell the difference in results. Saves money.

My doctor suggested supplementing and it's been going well. Last checkup numbers looked better than before.
