Are you wondering whether CircO2 supplements are worth your investment? My name is Michael Thompson, I’m 53 years old, and I work as a financial advisor here in Denver. I’ll be honest, I wasn’t initially planning to write CircO2 reviews, but my own experience with declining energy levels pushed me to explore nitric oxide supplements.
Like many people my age, I started noticing subtle changes: feeling winded after climbing stairs, afternoon energy crashes that seemed to hit harder than before, and that general sense that my body wasn’t functioning quite like it used to. My doctor mentioned that nitric oxide production naturally decreases with age, which can affect circulation and energy levels. After some research, I decided to try CircO2, mainly because the lozenge format seemed more convenient than swallowing multiple pills daily, and the 90-day guarantee meant I had nothing to lose.
For those unfamiliar with CircO2, it’s a nitric oxide booster supplement created by Advanced Bionutritionals that comes in quick-dissolving lozenge form. The product claims to address what they call “sluggish endothelium”, essentially the aging of blood vessel linings that can restrict circulation and energy flow. What initially caught my attention was that their formulation is based on the research about nitric oxide’s role in cardiovascular health.
The supplement contains ingredients like hawthorn berry extract, beetroot powder, and L-citrulline, all of which have some scientific backing for supporting circulation. While I approached it with healthy skepticism, the gradual improvements I experienced over several months – better mental clarity, more consistent energy, and less joint stiffness – were significant enough that I felt compelled to share my experience and research what other users have reported.

Understanding The CircO2 Supplement
CircO2 supplements are designed based on research that identified the crucial role of nitric oxide in maintaining healthy endothelial function. The supplement targets what manufacturers call “sluggish endothelium” – a condition where the inner lining of blood vessels becomes less efficient at regulating blood flow.
According to CircO2 reviews, users appreciate the convenient lozenge format, which dissolves quickly and delivers ingredients directly into the bloodstream. This delivery method appears to be more effective than traditional capsules, based on customer feedback found in various CircO2 reviews.
How Does CircO2 Work?
The CircO2 Nitric Oxide Booster operates on a scientifically backed mechanism that addresses age-related circulation issues. The supplement works by:
Targeting Endothelial Function: The endothelium is a thin layer of cells lining blood vessels. When this layer becomes sluggish with age, blood flow decreases, leading to various health issues.
Boosting Nitric Oxide Production: CircO2 supplements provide ingredients that naturally increase nitric oxide levels in the body. Nitric oxide acts as a vasodilator, helping blood vessels relax and expand for improved circulation.
Supporting Cardiovascular Health: By improving blood flow, the supplement helps maintain healthy blood pressure levels and supports overall heart health.
Most CircO2 reviews mention noticeable improvements in energy and mental clarity within days of starting the supplement, suggesting the mechanism works relatively quickly for many users.
CircO2 Key Ingredients Analysis
Based on CircO2 reviews and scientific research, here are the primary ingredients:
Hawthorn Berry Extract: A Traditional medicinal herb known for supporting cardiovascular health. Research published in the International Journal of Cardiology confirms its endothelial protective properties.
Beet Root Powder: Rich in natural nitrates that convert to nitric oxide in the body. Studies show beetroot supplementation can enhance cardiorespiratory endurance and blood circulation.
L-Citrulline: An amino acid that converts to L-arginine, promoting nitric oxide production. Research in the Experimental Physiology journal demonstrates its effectiveness in improving blood flow in older adults.
Vitamin B12: Supports nerve function and contributes to nitric oxide production. Studies show it can improve arterial function and provide cardiovascular benefits.
Vitamin C: Acts as an antioxidant and supports overall vascular health.
