What OptiNOs® Does

See how it works

01

Turns On Protein Synthesis

OptiNOs® turns on muscle protein synthesis by triggering your mTOR receptors, so more of the protein you already eat goes straight into building muscle.*

02

Turns On Nitric Oxide

OptiNOs® triggers eNOS, so your body turns more amino acids into nitric oxide. That means more blood flow and more nutrients getting to your muscles.*

03

Increases ATP Production

OptiNOs® also boosts ATP, the fuel behind strength and muscle building. More ATP means faster muscle firing and more endurance in every set.*

04

Improves Lactate Clearance

OptiNOs® flushes lactic acid out of your muscles faster with more nitric oxide, and ramps up the enzymes that break lactic acid down so you recover quicker.*

Know exactly what you're taking

No fillers, no hidden proprietary blends. Every capsule is a clinically dosed, 100% natural formula, with 90 capsules per bottle.

The magic is the teamwork. A patented complex of three natural extracts hits different jobs at the same time, working with your body's own nitric oxide pathway so they stack up to way more than any one could do alone.

Better together: Cissus builds it, Curcuma protects it, and Trachyspermum fires up your natural nitric oxide to feed it. Working in sync, the blend keeps the muscle-building pathway switched on and blood flowing from your first rep to full recovery.

How to use

1Take 3 capsules daily with water.
2Best taken 30 to 45 minutes before training.
3Use consistently for 8+ weeks for best results.

Got Questions?

Frequently asked

No. OptiNOs® is a 100% natural supplement that is proven to be safe.

Yes! OptiNOs® is safe to combine with other supplements. We recommend pairing OptiNOs® with our OptiForce Pre-Workout for better results while training, and with Whey+ protein to maximize muscle building after training.

Proprietary blends have gotten a bad reputation in the supplement industry because of brands that under-dose ingredients or add an ingredient just for the label claim. This is NOT the case with OptiNOs®. OptiNOs® is a proprietary blend to protect the huge amount of research that went into creating it. We tested over 300 herbal extracts before we found the 3 we use in OptiNOs® today.

This is a very common question we get when people first look at the supplement facts. The clinically tested ingredient in this formula is OptiNOs®, which is made up of 3 herbal extracts. Those 3 extracts were fractionized to pull out the active components that assist in muscle building and nitric oxide production. We added L-Citrulline and L-Arginine to give you an extra boost when taking OptiNOs®.

OptiNOs® is made up of 3 specific fractionated parts of herbal extracts, chosen based on their optimal function, compatibility, and how they work together to increase muscle building, blood flow, mTOR signaling for protein synthesis, ATP production, and lactic acid clearing.
