The Science Behind Twinlab Ripped Fuel 5x:

Twinlab Ripped Fuel 5x claims to burn calories faster, preserve lean muscle, enhance nutrient absorption, reduce body fat, and fuel increased energy levels. Let’s take a look at the ingredients and see if these claims hold up.

First is vitamin B12. Gayle Nicholas Scott, doctor of pharmacology, said that, “Vitamin B12 has been touted as an energy enhancer and metabolism booster. These claims are based on the fact that correcting vitamin B12 deficiency should improve the associated symptoms of fatigue and weakness; however, in the absence of a nutritional deficit, vitamin B12 supplementation does not affect physical performance.” In other words, overloading on vitamin B12 will not result in weight loss or increased metabolism.

Second is chromium. Studies involving chromium are inconclusive. Some have shown that chromium increases insulin sensitivity and glucose metabolism, but others have shown that chromium supplementation is only reliable for increasing the amount of chromium in one’s system (useful for diabetics), but not proven as an aid in increasing metabolism. Also, chromium has a high excretion rate and can be found naturally in several different types of food including: apples, bananas, beef, broccoli, chicken, eggs, grape juice, green beans, green peppers, liver, orange juice, and spinach.

Third is caffeine. Twinlab Ripped Fuel 5x only has 99 mg of caffeine per serving which is well short of the recommended, clinically tested amount of 400 mg caffeine in order to affect metabolism and weight loss.

Finally, Twinlab Ripped Fuel 5x contains two proprietary blends containing various roots, barks, and fruits. I am not sure whether the amount of each blend is significant enough to increase energy levels or reduce body fat, or if the ingredients in the blends themselves are truly effective in that regard. Also, side effects include nervousness, irritability, sleeplessness, and sometimes, rapid heartbeat. Most of this comes from the caffeine.

Twinlab Ripped Fuel 5x Policies:

I could not find any money back guarantee on the website nor did I see any policies addressing returns and/or exchanges. That is usually a red flag because most quality products offer some kind of satisfaction guarantee.

Twinlab Ripped Fuel 5x Lowest Price:

One bottle of Twinlab Ripped Fuel 5x contains 40 tablets and they recommend you take 2 tablets per day with meals. It costs $27.99 a bottle. So, one bottle lasts you 20 days. The price isn’t shockingly expensive, but it’s not exactly a great deal either. You can find other supplements with the same ingredients for less.

Does Twinlab Ripped Fuel 5x Work:

Twinlab Ripped Fuel 5x claims to do a lot of things for your health. None of these is backed up by clinical trials or scientific evidence. They don’t site any kind of double blind study testing people on Twinlab Ripped Fuel 5x vs. people taking placebos. Most quality weight loss supplements will provide some kind of research or evidence to support their claims. Twinlab Ripped Fuel 5x seems a little over the top and unbelievable to me. Probably not your best option if you’re looking for help losing weight.
