Cardio Elite®

Power Your Body’s Vital Flow

Voted best pre-workout product of 2025 by Mindful Awards! 

Good circulation is the foundation of feeling your best—mentally and physically. But most supplements only support part of the equation. Cardio Elite takes a smarter approach. It blends targeted nitric oxide-promoting nutrients like potassium nitrite/nitrate and L-citrulline with circulation-supporting herbs to aid healthy blood flow throughout the body. Thanks to our advanced nanoemulsion delivery technology, this formula works fast to help you stay sharp, energized, and perform at your best.

Why Cardio Elite?

  • Boost Circulation Naturally - Potassium nitrite/nitrate and L-citrulline help your body produce more nitric oxide to aid blood flow.
  • Supports Healthy Blood Pressure - Rhamnan sulfate, a premier algae from Japan, helps relax blood vessels and maintain normal blood pressure levels.
  • Strengthens Vascular Health - Time-honored botanicals including Hawthorn berry, Dan Shen, Notoginseng, and Ginkgo support healthy blood vessels and capillaries for overall blood flow and circulatory function.
  • Sharpens Mental Focus - Healthy oxygenation to the brain supports clarity, alertness, and cognitive performance.
  • Improves Energy & Stamina - Healthy blood flow to extremities and muscles supplies the power and stamina needed to get you through workouts or any recreational activity.

Stuff tasted like shit!!! First

"Stuff tasted like shit!!! First time I took it, I wretched. I tried a second time and almost puked!! This crap is putrid! I looked forward to getting this product but I could not stomach it. You should also have mentioned that when swallowed, it feels like lava going down your throat. I thought I had a bad batch of this swill. Terrible product!! You should pull it from the market. And I bought two bottles of this shit. Waste of money!!!"

"This has been a game changer for my husbands blood flow!"

— Jennilyn G. (5/5)

Absolutely terribly tasting

"Avoid this product! It was shocking to me to see a "new taste" label on this because it's truly terrible. I have several of their other products and none of them are great tasting - but this is the absolute worst. I managed to get it down 3x before I just couldn't take it anymore and dumped the rest of it out. I reached out to the company initially thinking maybe I got a bad batch and received basically a "sorry about that" message instead of a refund."
