My name is Thomas Anderson, a 47-year-old civil engineer from Sacramento, California, and like many men approaching their fifties, I began experiencing concerning changes in my energy levels and overall vitality. Despite maintaining a relatively active lifestyle and trying various supplements over the years, I found myself struggling with afternoon fatigue, reduced mental clarity, and that general feeling that my body wasn’t performing like it used to. After researching numerous options and reading countless CircO2 reviews & complaints online, I decided to give this nitric oxide booster a try, mainly because the science behind nitric oxide production seemed promising and the lozenge format appeared more convenient than traditional pills.
Before committing to CircO2, I spent considerable time analyzing CircO2 reviews & complaints from real users to set realistic expectations for my own journey. I’ll be completely honest – during the first week of taking CircO2 lozenges, I didn’t notice any significant changes and was starting to wonder if I’d made another poor supplement choice. However, I committed to using it consistently for a full month, and by the end of that period, I experienced notable improvements in my energy levels, mental focus, and overall sense of well-being. This experience taught me that genuine health improvements take time and patience, rather than expecting overnight transformations that many supplements promise but rarely deliver.

What Is CircO2?
CircO2 is a nitric oxide booster supplement developed by Advanced Bionutritionals that comes in a unique quick-dissolving lozenge format. During my research phase, I learned that this supplement specifically targets what the manufacturer calls “sluggish endothelium” – essentially, the aging process that affects the inner lining of our blood vessels and reduces their ability to regulate blood flow effectively. The product is designed to address the natural decline in nitric oxide production that occurs as we age, which can significantly impact circulation, energy levels, and overall cardiovascular health.
What initially attracted me to the CircO2 nitric oxide booster was its foundation in Nobel Prize-winning research about nitric oxide’s crucial role in cardiovascular function. The supplement contains a carefully selected blend of natural ingredients, including hawthorn berry extract, beetroot powder, and L-citrulline, all of which have scientific backing for supporting healthy circulation and nitric oxide production. Unlike many supplements that require swallowing multiple large capsules, CircO2’s lozenge format dissolves quickly under the tongue, allowing for direct absorption into the bloodstream.
The convenience factor was significant for me as someone with a busy schedule. I found that I could easily take a lozenge in the morning without worrying about timing it with meals or carrying water bottles. The manufacturer claims that this sublingual delivery method is more effective than traditional capsules because it bypasses the digestive system, allowing the active ingredients to enter the bloodstream more rapidly and efficiently.
CircO2 Ingredients List
Based on my research and experience with the product, CircO2 contains the following key 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.

Benefits of CircO2
Through my personal experience with CircO2, I discovered several notable benefits:
- Enhanced Energy Levels: Consistent energy throughout the day without afternoon crashes
- Improved Mental Clarity: Reduced brain fog and better cognitive function
- Better Circulation: Noticeable improvement in blood flow, especially to extremities
- Cardiovascular Support: General heart health benefits and improved endurance
- Faster Recovery: Quicker recovery from physical activities and exercise
- Better Sleep Quality: More restful sleep and easier morning wake-ups
- Reduced Joint Stiffness: Less morning stiffness and improved mobility
- Enhanced Physical Performance: Better stamina during workouts and daily activities
How Does CircO2 Work?
From my understanding and personal experience, CircO2 works through a multi-faceted approach that addresses the root cause of age-related circulation issues. The supplement primarily functions by supporting the endothelium, which is the thin layer of cells that lines the inside of blood vessels. As we age, this endothelial layer becomes less efficient at producing nitric oxide, a crucial molecule that helps blood vessels relax and expand for optimal blood flow.
The ingredients in CircO2 work synergistically to boost nitric oxide production through multiple pathways. The beetroot powder provides natural nitrates that the body converts to nitric oxide, while L-citrulline supports this process by converting to L-arginine, another precursor to nitric oxide production. The hawthorn berry extract provides additional cardiovascular support by protecting the endothelial cells from oxidative damage and supporting their function.
What I found particularly impressive about CircO2’s mechanism is how the lozenge format allows for sublingual absorption, meaning the active ingredients bypass the digestive system and enter the bloodstream directly through the tissues under the tongue. This delivery method appeared to produce faster results compared to the traditional capsules I had used previously. The increased nitric oxide production leads to vasodilation, where blood vessels relax and widen, allowing for improved circulation throughout the body. This enhanced blood flow delivers more oxygen and nutrients to tissues, resulting in the energy and mental clarity improvements I experienced during my time using the supplement.

⭐⭐⭐⭐ Linda Chen, 45, Seattle, WA “Good product overall, but it took about 6 weeks before I really noticed significant changes. The taste is pleasant, and it’s easy to remember to take. My main complaint is that it’s only available online, which can be inconvenient for reordering.”
⭐⭐⭐ Robert Wilson, 61, Chicago, IL “Mixed results for me. I did notice some improvement in my energy levels after a couple of months, but not the dramatic changes that some other reviews mentioned. Still, it’s helped enough that I continue taking it, though I wish the price were a bit lower.”
