PhenQ Customer Reviews

Noticing a difference
I been overweight from young ago, but just recently had a wake up call. While on a family cruise, I couldn’t join my family for dinner as I didn’t fit in the chair. That’s when I stopped and told myself I needed to lose weight. Since then I have started doing exercise, eating healthier and taking PhenQ (ordered the 2+1 package). A lot of people thought I couldn’t do it, but here I am – 44 lbs lighter than when I first started taking PhenQ. I can now be more active in day to day life and I have found applying for jobs easier and more accessible now that I have ethereal mobility to do all jobs required. – Taiylah P.

Effective Product
In recent years I gradually started to gain weight. Once I passed 176 lbs I began to get frustrated, tried several diets (ineffective) and to improve my overall lifestyle but without results. I even went up to 187 lbs. Then I found PhenQ and started taking it. I think it took me about 2 weeks to start seeing results but then they started coming in and I took after photos to compare. I lost 11 lbs in 1 month thanks to PhenQ! Overall I feel more confident, I can see my wife proud of my change and I have so much more energy to be effective all day at work and still have energy to play with my son at night. – Ghislain R.

No Major Results
I’ve been using Nugenix Thermo for a month and I’ve noticed some increased energy during workouts, but I haven’t seen significant weight loss yet. I experienced minor stomach aches after meals and some headaches, though. I’ll give it another month, but not sure if it’s worth the price. – Dberg

Do Thermogenic Fat Burners Work?

Various studies have linked the use of thermogenic fat burners to a number of health benefits, including increased energy expenditure, metabolic rate, fat burning, and sustainable weight loss.

A research study published in the Journal of International Society of Sports Nutrition suggests that intake of specific thermogenic supplements has shown promise for a constant increase in metabolic rate, reducing fatigue, and boosting caloric expenditure without producing adverse hemodynamic reactions.^[2]

Another publication in the International Journal of Obesity confirmed that using thermogenic fat burners can effectively help reduce fat mass and support weight maintenance.^[3]

Key Ingredients to Look for in Thermogenic Fat Burners

Caffeine

Caffeine is a key ingredient in thermogenic fat burners because of its immense health benefits. A study in Purinergic Signaling notes that both human and animal studies have demonstrated the effect of caffeine intake on weight loss.^[4] It plays a crucial role in appetite suppression, energy consumption, and metabolic alteration, making it an ideal agent for weight loss.

Green tea extract

Green tea extract in thermogenic fat burners works to boost thermogenesis and promote fat oxidation (helps the body to burn fat for energy, especially abdominal fat). A publication in Advances in Nutrition investigated the effect of green tea on fat oxidation and exercise.^[5]

Capsaicin

The primary reason why capsaicin is popular in thermogenic fat burners is because of its ability to support negative energy balance and promote fat oxidation. According to a study published in the Oxford Journal of Chemical Senses, there is evidence that capsaicin can help promote energy expenditure and boost fat oxidation.^[6]

Glucomannan

Glucomannan is a soluble fiber present in tubers, roots, and plant bulbs. A research study published in Nutrients notes that ingestion of glucomannan can contribute to prolonged gastric emptying and promote a feeling.^[7]

Yohimbe extract

Yohimbe extract has been used in thermogenic fat burners because of its ability to induce fat oxidation. A publication in the International Journal of Molecular Science notes that Yohimbe helps increase norepinephrine, a compound known for enhancing metabolism and promoting breakdown of fat.^[8]

Are Thermogenic Fat Burners Safe to Use?

While thermogenic fat burners are claimed to be safe for use by most people, they contain stimulant ingredients like caffeine linked to side effects and health risks like increased heart rate, anxiety, jitters, digestive issues, insomnia, and liver and heart complications. Yohimbe can interact with medications such as antidepressants and may also cause anxiety.
