CircO2 from Advanced Bionutritionals is a fast-dissolving sublingual lozenge formulated to naturally enhance nitric oxide levels to support healthy blood flow, sustained energy, sharper mental focus, and cardiovascular health especially for adults over 40.

β¨ General Description
CircO2 is a nitric oxide boosting formula developed by Advanced Bionutritionals that comes as a quick-dissolving sublingual lozenge. It is designed to increase nitric oxide production in the body, promoting vasodilation, improved circulation, energy, stamina, and cognitive function, particularly supporting adults as they age.
The formulation supports nitric oxide generation through multiple pathways to enhance consistency and efficacy. It is vegan, non-GMO, and free from common allergens such as gluten and dairy, ensuring a clean and safe supplement for daily use.
βοΈ How It Works
CircO2 works by stimulating the body's production of nitric oxide (NO), a molecule crucial for relaxing blood vessels and improving blood flow.
Using a sublingual lozenge allows for faster and more effective absorption by bypassing the digestive system. The formula supports both nitrate conversion (via beetroot) and amino acid precursors like L-citrulline, ensuring reliable nitric oxide generation even if one biological pathway is less efficient.
This results in better oxygen and nutrient delivery, natural energy boost without caffeine, strengthened cardiovascular function, enhanced mental clarity, and quicker muscle recovery.
πΏ Ingredients
- π§¬L-Citrulline: Amino acid precursor to L-arginine, promoting sustained nitric oxide production and supporting circulation, stamina, and recovery.

Several years ago I started having blood pressure problems despite exercising and eating correctly. After two months of taking CircO2 my blood pressure improved to healthy levels. Since then I have kept up using CircO2 daily and have had no problems since.
