Ab Cuts Sleek and Lean Thermo Rise O2 Review
The Ab Cuts Sleek and Lean product line has a new edition: Thermo Rise O2. This product is designed to promote weight loss by helping the body burn excess calories and fatty acids. It is also a workout enhancer that increases energy and endurance while boosting mental alertness.
Thermo Rise O2 can also be consumed in the morning to reduce fatigue, increase energy, and fight body fat, all while you go about your daily tasks.
Thermo Rise O2 is advertised as being a safe and natural energy booster that won’t trigger unpleasant side effects such as jitteriness or nausea. I decided to put this claim to the test, and researched the main ingredients in its formula.
Key Ingredients in Thermo Rise O2
Here are the ingredients listed on the bottle. These ingredients are responsible for making Thermo Rise O2 a potent weight loss aid:
Conjugated Linoleic Acid (CLA) – 850 mg refers to a group of chemicals found in the fatty acid linoleic acid.
There has been extensive research investigating CLA’s effects on body composition and weight loss. One study analyzed CLA’s effects after 1 year of supplementation. Results show subjects given CLA had greater lean body mass and reduced body fat. These results were not associated with diet or exercise. CLA did not exhibit any adverse side effects during the dosing period.
The recommended dose for CLA is 1.8-3.4 g daily. Thermo Rise O2 might not contain enough to achieve maximum results, though it might still benefit weight loss.
Green Coffee Bean – 150 mg refers to the coffee bean before it is roasted. Green coffee bean has shown in clinical studies to promote weight loss.
In one study, 16 volunteers were given various amounts of green coffee bean or a placebo. Subjects did not change diet or exercise habits. Results show subjects dosed with green coffee bean extract had reduced body fat mass, whereas volunteers given a placebo showed no significant improvement.
A follow-up on this study revealed 14 out of 16 volunteers were able to maintain their lowered weight after the study was over. This may suggest green coffee bean helps regulate fat.
This study was conducted using doses of 700 mg and 1050 mg. Thermo Rise O2 probably doesn’t contain enough to deliver results achieved in the study.
Raspberry Ketone – 70 mg increases metabolism and stimulates a hormone called adiponectin that regulates adipose tissue. Raspberry ketone is chemically related to the stimulant synephrine and offers a minor energy boost.
Although studies conducted on rats suggest raspberry ketone reduces body weight, there isn’t enough evidence from human clinical studies to determine its efficacy or a recommended dose.
Coleus Forskohlii – 100 mg is commonly known as forskolin. Coleus forskohlii stimulates thermogenesis in brown adipose tissue and promotes weight loss. It also increases oxygen consumption and decreases body temperature, making it a useful workout enhancer.
Cordyceps – 100 mg is a fungus derived from China, Nepal, and Tibet. I couldn’t find any evidence linking cordyceps to weight loss; however, it is a proven workout enhancer.
A study was conducted on 20 healthy elderly adults to test cordyceps’ effects on exercise performance. After 12 weeks, results showed cordyceps improved the metabolic and ventilator threshold. Researchers conclude “supplementation with cordyceps sinensis improves exercise performance and might contribute to wellness in healthy older subjects.”
This study used a dose of 333 mg cordyceps. Thermo Rise O2 probably doesn’t contain enough to deliver the same results.
Caffeine – 150 mg boosts metabolism and induces thermogenesis. A study conducted on obese female subjects showed significant weight loss after 2 months of supplementation. Caffeine also influences energy balance and offsets exercise-induced fatigue.
Caffeine is proven effective at doses of 100 mg daily. Thermo Rise O2 contains an efficient amount.
Side Effects and Warnings
Some ingredients contained in Thermo Rise O2 pose a risk of certain side effects.
Medical experts are concerned conjugated linoleic acid might increase the risk of developing diabetes or worsen an existing diabetic condition. People at risk for diabetes should avoid using this product.
Raspberry ketone and caffeine are stimulants which might induce feelings of restlessness, jitteriness, shakiness, and lightheadedness. These stimulants may even raise blood pressure and cause the heart to beat rapidly.
If you experience any of these symptoms, stop using Thermo Rise O2 and consult your doctor. Additionally, several ingredients have not been proven safe for pregnant women. Stay on the safe side and avoid using this product if you are pregnant or breastfeeding.
How to Use Thermo Rise O2
Thermo Rise O2 has specific guidelines for usage, which can be found on the packaging label.
For adults, take 2 soft gels in the morning. Allow yourself time to assess tolerance levels. If you are feeling fine by the afternoon, go ahead and take 1-2 soft gels during lunchtime. Limit dosage to 1-2 soft gels in the morning if you are still feeling effects by lunchtime.
Do not exceed 4 soft gels in a day for risk of toxicity. Also, do not consume Thermo Rise O2 within 6 hours of bedtime, as it will make it hard to sleep.
What Customers Are Saying
Unfortunately, I could only find one source for customer feedback: GNC.com. These customer reviews speak highly of Thermo Rise O2, though they may be biased because GNC is an official retailer.
“I think this product is absolutely fantastic. I have been taking it for about one month and definitely feel less bloated and thinner. It has great ingredients and you feel 100% better using it. Also, there is no jittery feeling that so many diet products demonstrate. A great deal for the money. I know too since I formerly used prescription phentermine and lost over 46 pounds.” – Sandra_Eichler
“I noticed taking this supplement help me get the energy I need to work out. I find myself sweating more than normal which is awesome. I would recommend to anyone who wants that extra boost in their workout. It works for me.” – Chriselle76
According to these customers, the product is well worth the money. But, I wish I could locate customer reviews that give a slightly more balanced opinion or mentions adverse side effects.

Is It Recommended?
Thermo Rise O2 contains effective ingredients, but I’m not sure this formula contains the required dosing amounts for several ingredients, which means it might prove ineffective.
Considering the mild price tag on this product, it’s worth checking out. If you are interested in thermogenic weight loss, or want an energy boost throughout the day, you might find this product enjoyable.
