Fireball Weight Loss Supplement

By Lisa Sefcik paralegal ; Updated July 18, 2017

While not expressly marketed for weight loss, Precision Engineered Fireball supplements are sometimes used for that purpose. Precision Engineered Fireball supplements are not intended to diagnose, treat, cure or prevent any disease – nor are they approved by the U.S. Food and Drug Administration to do so. Before taking a dietary supplement for weight loss or any other reason, talk with your physician.

About the Manufacturer

Precision Engineered Fireball supplements are manufactured by U.S. Nutrition, based in Holbrook, N.Y. Two products are available to consumers: Precision Engineered Fireball Liqui-Fusion and Fireball TNT. While the latter supplement is marketed by the manufacturer as a pre-workout "intensity booster," Fireball Liqui-Fusion, a product taken for metabolic support, purportedly makes your body release epinephrine and causes "thermogenesis" – an increase in body heat that makes you burn calories faster.


According to the U.S. National School of Medicine Dietary Supplements Label Database, the ingredients in Precision Engineered Fireball Liqui-Fusion include caffeine, green tea and protein in the manufacturer's proprietary Liqui-Delivery, Liqui-Force and Magma Heat blends. Fireball TNT also contains caffeine and a proprietary Fireball TNT complex. According to the manufacturer's instructions, Fireball Liqui-Fusion, consumers should take three of the softgel supplements twice a day with meals spaced at least four hours apart. Fireball TNT, also a softgel supplement, is taken 30 to 60 minutes before you exercise. The manufacturer advises taking one to three softgels, but no more than six per day.


Fireball supplements contain caffeine and green tea, two ingredients typically found in over-the-counter weight loss supplements. According to MayoClinic.Com, caffeine suppresses your appetite, temporarily increases your metabolism and functions as a diuretic. It may act as a short-term weight loss aid, but there's no scientific evidence to suggest that you'll notice significant or permanent results. Green tea is also said to decrease your appetite and boost your metabolism; however, there's no conclusive evidence to support these claims. A side effect of taking caffeine in excess amounts include anxiety, nervousness and insomnia, cautions MayoClinic.Com.


The manufacturer of Fireball supplements includes numerous herbal ingredients in its proprietary blends, such as ginkgo biloba extract, yohimbine, cayenne pepper, white willow bark, sesame oil and hoodia gordonii. But natural or herbal ingredients don't make your dietary supplement safe to take, cautions the FDA. Yohimbe, for example, can cause undesired side effects, such as high blood pressure, a rapid heart rate, dizziness, nausea and tremors, according to the National Center for Complementary and Alternative Medicine, or NCCAM. Yohimbe is also dangerous when mixed with monoamine oxidase inhibitors, tricyclic antidepressants and medications for high blood pressure and schizophrenia. Side effects associated with ginkgo biloba are nausea, diarrhea, headache and severe allergic reactions. Additionally, ginkgo biloba can cause increased bleeding and may be dangerous when taken with blood-thinning medications.

Dietary Supplements

The FDA has approved only a handful of prescription drugs for weight loss. MayoClinic.com points out that most of these can be used for a maximum of 12 weeks and aren't generally prescribed unless you are obese or have health problems related to weight gain. The miracle claims of weight loss supplements have not been assessed by the FDA for veracity – nor do you have any assurance but the manufacturer's that they are safe to use. When sorting out claims you hear about dietary supplements like Precision Engineered Fireball, treat all with skepticism. One scientific-sounding term to expressly disregard is "thermogenesis," according to the Federal Trade Commission. A safer, surefire way to lose weight is to eat fewer calories than you burn and get regular exercise.
