8-FX is a diet pill that claims to do the following:

“Support metabolism

Support fat oxidation

Support optimal thyroid activity

Increase focus and alertness

Increase energy

Support mood

Increase norepinephrine, the “thermogenic” activator

Support cAMP-mediated fat breakdown” (website)

This 8-FX review will breakdown each of the ingredients contained 8-FX and explain the cost and guarantee (or lack thereof) associated with 8-FX to help you determine if this is the product for you.

8-FX Ingredients

Chromium (200 mcg) has been shown to cause weight loss in some clinical trials, but others have found that it does not.

Proprietary Blend for Focus, Energy and Mood Activators 585.5 mg

Neuravena Wild Green Oat Extract

Caffeine (50 mg per serving) does contribute to weight loss, but you are unlikely to see much of an effect from 50 mg.

DMAE is supposed to positively affect mood, but studies have shown some dangerous effects. More research is needed on DMAE.

Proprietary Blend for Lipid Metabolism Activators 395.8 mg

Coleus Forskolii does contribute to weight loss, but 8-FX does not say how much coleus forskolii it contains.

Raspberry Ketones have been shown to cause weight loss in mice when included as 1% of the total diet. To get 1% of your total diet as raspberry ketones you would most likely have to take dozens of 8-FX diet pills. DO NOT TAKE MORE 8-FX DIET PILLS THAN RECOMMENDED! More human research needs to be done on raspberry ketones.

Evodia Extract has proven to cause weight loss in mice, but more human research is needed to determine its effect on human weight loss.

Advantra Z contains synephrine, which has been shown to contribute to weight loss. The important thing with synephrine is the concentration (the higher the better). Unfortunately, 8-FX fails to disclose the concentration of synephrine it contains.

Green Tea is a clinically proven diet pill. To be effective, green tea has to be taken in doses of 300 mg or more per day. It is extremely unlikely that 8-FX contains enough green tea to cause weight loss.

Cnidium Extract is supposed to help circulation, but it does not contribute to weight loss.

7-Methyoxy-8-Isopentenoxycoumarin

Yohimbe mobilizes fatty acid, causing weight loss. 8-FX hides the amount of yohimbe it contains, making it impossible for this 8-FX review to determine if there is enough yohimbe to cause weight loss.

Japanese Knotweed Extract

8-FX Cost

The cost of 8-FX is $47.89 for 80 capsules. If you take the recommended 4 capsules per day, one bottle will last 20 days. This is expensive for a diet pill. Although 8-FX does contain several clinically proven ingredients, they are included in proprietary blends (which usually means there is very little of each ingredient included).

8-FX Guarantee

Medical Research Institute (MRI) is the manufacturer of 8-FX diet pills. The MRI website has details of 8-FX, but it says nothing about a product guarantee. They have a customer service phone number listed on the website, but when we called to ask about a guarantee, the only options given by the automated system were to enter an extension or hang up. Thus, we cannot say whether 8-FX has a guarantee or not. It does seem strange that contacting the company is so difficult.

8-FX Conclusion

This 8-FX review finds that while 8-FX does contain several clinically proven diet pills, it fails to mention how much of each ingredient is included. This is necessary to be able to compare products against each other and against the clinical trials. We recommend finding a diet pill that lists the amounts of all their ingredients and includes the proper amounts of proven ingredients.
