1. Is CircO2 safe to take?
Yes. The ingredients in CircO2 have a long history of safety and have been used by thousands of customers without reports of serious side effects. The formula is designed to improve blood flow, so if you have low blood pressure or are on medication, it's always a good idea to consult with your physician before starting any new supplement.
2. How long will it take for me to feel the effects of CircO2?
Many people feel an effect in just a few minutes, while for others, it may take a few days or weeks to notice significant changes. Each person's body responds differently. We recommend you take CircO2 consistently for at least the first month to give the ingredients time to fully restore your nitric oxide levels. You are protected by our 90-day, "down to the last lozenge" guarantee, so you have plenty of time to see the benefits for yourself.
3. I already have a lot of energy and healthy blood pressure.
How can CircO2 help me? That's fantastic! Continued healthy habits are key. However, the fact is that your body's ability to produce nitric oxide naturally decreases with age, regardless of your current health. CircO2 helps protect your cardiovascular system and endothelium (the inner lining of your blood vessels) as you get older, ensuring you can maintain that youthful energy and vitality for years to come.
4. Will taking CircO2 interfere with my oral hygiene products like mouthwash?
Good oral hygiene is important. While antiseptic mouthwash can temporarily disrupt the bacteria on your tongue, CircO2’s patented lozenge formula is designed to give the ingredients enough time to mix with these special bacteria and start making nitric oxide right in your mouth. You can continue your regular routine without worry.
5. How often should I take CircO2?
Many people get great results from taking just one tablet in the morning. For the first week or two, we suggest you take CircO2 twice a day to fully saturate your body and restore your nitric oxide levels. After that, you can try reducing your intake to once a day and see how you feel.
6. Do I have to let the lozenge dissolve completely in my mouth?
It is best to let the lozenge dissolve completely for maximum effect. However, if you're in a hurry, it's okay to let it dissolve for a minute or two and then chew the rest. This still gives the ingredients enough time to mix with the bacteria and kickstart nitric oxide production.
7. Does CircO2 contain caffeine or other stimulants?
No. CircO2 does not contain any caffeine, stimulants, or artificial ingredients that can give you a jittery, artificial energy jolt. Instead, it works naturally with your body to improve blood flow, so all you feel is the clean, high energy you had when you were younger.
8. Is my purchase protected by a guarantee?
Yes. We are so confident you will love CircO2 that every purchase is backed by our "Down to the Last Lozenge" guarantee. If you are not completely satisfied for any reason, simply return the box—even if it's empty—within 90 days for a full refund of your purchase price (you only pay return shipping).
