Get More Out of Your Workouts with Total Nitric Oxide

Getting the best results possible from your workouts often comes down to the finer details. The average person likely doesn’t reap all the benefits of exercise unless they optimize nitric oxide (NO), a crucial component of overall health, performance, and recovery that’s often overlooked.

We developed the best nitric oxide formulation we could, so you can get the most out of your workouts.

How Total Nitric Oxide Works

• Helps Circulation via NO pathway support†
• Aids the delivery of oxygen and nutrients to working tissue†
• Promotes cellular integrity†

Nitric oxide is a naturally-occurring compound, synthesized in the body from the amino acids L-arginine and L-citrulline. It is a vasodilator, meaning that it dilates (or widens) the blood vessels, allowing blood to flow throughout the body with less restriction.†

Boosting your body’s nitric oxide production is like shifting into a higher gear during intense exercise, ensuring that your muscles are provided with the oxygen and nutrients needed while removing excess waste that may cause fatigue — promoting performance, recovery, and growth.

Taking Total Nitric Oxide regularly throughout the day also supports cellular integrity, as well as cardiovascular health when combined with a healthy, active lifestyle.†

The Building Blocks Your Body Needs to Maximize Nitric Oxide Production

Though NO production already occurs in the body, you need to support its multiple steps to ensure complete optimization. Total Nitric Oxide is formulated with ingredients chosen specifically for their ability to provide the building blocks your body needs to optimize its natural nitric oxide production.†


Boosts aerobic endurance and time to exhaustion during exercise.† One study in The Journal of Applied Physiology found that joggers on arginine were able to process oxygen more efficiently and extended their time to exhaustion by more than two minutes when tested only one hour after ingestion. In 2017, the European Journal of Clinical Nutrition reported that soccer players taking arginine significantly boosted their aerobic performance over a placebo.†


Promotes work capacity and recovery.† A 2017 study on women with resistance training experience showed that citrulline promoted work capacity during lifting, boosting the subjects’ upper and lower body performance in just one dose.† The Journal of Strength and Conditioning Research reported that male lifters who took citrulline before a workout were less sore
24—and 48—hours later.

Careflow® Mango Fruit Powder

According to two studies, mango fruit powder improves circulation throughout the circulatory system. So naturally, we included Careflow® Mango Powder. Careflow® has been clinically shown to aid microcirculation by enhancing eNOS activity, the enzyme required to convert arginine to NO.

Fermented Beets

Contains twice as many nitrates as regular beet powder, rounding out complete support of NO production in the body.
