SPECIAL NOTE: This review is for the Slim Xtreme product marketed by Athletic Xtreme, which is now discontinued. It is not the same formula as the Slim Xtreme sold by Global All Wellness, LLC.
UPDATE: The Global Wellness products – both the Platinum Fat Loss Accelerator and the Diamond Fat Metaboliser Slim Xtreme products – are contaminated with the controlled substance sibutramine. Sibutramine was pulled from the U.S. market in 2010 due to concerns about unacceptable heart attack and stroke risks. The FDA is advising that you do not purchase these products, and if you have, that you do not use them. See the official FDA warning for more details.
Advertised as the “ultimate fat loss and appetite eliminator”, the Slim Xtreme fat burner cultivates a “hardcore” image. But once you delve into this review a little bit, you’ll find it’s a pretty ordinary formula—certainly not “hardcore.”
Let’s cut directly to the chase and take a closer look at the ingredients. Here’s what’s in each 500 mg capsule of Slim Xtreme…
1. Cocoa Seed Concentrate (standardized to 100 mg/caffeine per cap): It’s an established fact; as a central nervous system stimulator, caffeine does work as a thermogenic, and it will help with weight loss (although what you can expect from it rarely coincides with the claims of the retailers).
As such, it’s a common ingredient in most diet pills. Other cocoa-based xanthines are also common (i.e., theobromine), although there’s no evidence indicating these provide superior and / or additional benefits than those of caffeine.
2. AminoSlim-4: According to the product advertising, this is…
“… a combination of four energizing amino acids (Tyrosine, Proline, Tryptophan, and Carnitine) that have been structurally enhanced to create a powerful fat burning, mood elevating, and appetite suppressing effect.”
This is 100% marketing. There is no established evidence that this blend has any such effect. Even when you assess each ingredient individually, you’ll find that any effect is obtained at a dosage many, many times what is present in this formula.
Tyrosine, for example, is a contributor to mood and can help with cognitive performance—in a multi-gram dosage.
Carnitine has been used in fat burners for ages for its “supposed” fat burning powers. Problem is, clinical studies are inconclusive, contradictory, and performed with many, many times the dosage included in this formula.
Tryptophan is a essential amino acid that can act as a precursor to serotonin, an important “mood” neurotransmitter, and is often used as a natural sleep aid. Most positive studies have been performed on the tryptophan metabolite, 5-HTP.
However, even 5-HTP needs to be consumed in significant amounts to be helpful.
One study used 900 mg per day, and the other, 8 mg/kg/day (a 150-person weighs about 68 kg. To be compliant with the dosage of the second study, this person would require 544 mg of 5-HTP per day).
Proline is a non-essential amino acid that aids the body in metabolizing proteins and plays a critical role in the development of connective tissue like collagen and cartilage.
3. Aneurin DBE™ (Thiamine Disulfide Butyrate Ester): A form of vitamin B1 touted for its ability to improve brain function, cognition, etc.
4. Acai Berry Extract: Acai is a potent antioxidant. And, at the time of this writing, it’s pretty trendy to put acai in just about everything. A worthwhile ingredient, even if it won’t improve your mood, suppress your appetite, or help you lose weight.
5. Cha’de Bugre Extract: Commonly included in fat burners as an appetite suppressant. Unfortunately, this effect has not been confirmed by any reputable, controlled studies. Anecdotal evidence seems to suggest mild appetite supressing qualities.
As you can see, this formula is almost entirely based on speculation and wishful thinking and not any real science (there have not been any published studies performed on Slim Xtreme, for instance).
The proprietary blend prevents us from determining the exact amount of each ingredient, but simple mathematics clearly demonstrates the majority of ingredients cannot be present as any more than “label dressing.”
Cost-wise, this product “under-delivers” as well; a 45-cap bottle costs around $40. The recommended daily dosage is 1-3 caps, 1-2 times a day. 2 caps per day gives you a 22.5 day supply, 3 caps is a 15-day supply, 4 caps is an 11 day supply, and 6 caps is a 7.5 day supply.
Nonetheless, with each capsule containing 100 mg of caffeine, and a recommended dosage that can rise to 6 caps per day, you’ll definitely feel the effects of this product, although I would suggest there are much cheaper ways to obtain a caffeine buzz. If you’re sensitive to stimulants, you’ll need to be careful; Slim Xtreme side effects can include sleeplessness, irritability, increased heart rate, palpitations, etc.
Visitor feedback for Slim Xtreme is incredibly positive, much more so than we would have expected from a product with a relatively simple formula. At the same time, this product has recently been recalled—on allegations it is contaminated—possibly with prescription drugs. According to the Anabolic X web site…
“This voluntary recall has been initiated due to recent allegations that an ingredient contained in SLIM XTREME may not comply with all provisions of the Federal Food, Drug, and Cosmetic Act.”
If this turns out to be true, things will definitely not bode well for Anabolic X and Slim Xtreme. But it might explain why the product appears to be so effective and has so many raving fans…
