According to the advertising I reviewed, SoloSlim is the once-daily weight loss pill that's...
"... designed to help you safely slim down."Unfortunately, I highly doubt that's the case. Why? There are several major problems with SoloSlim®. Let's start with the first...
1) First of all, Health Canada has issued a product alert as a result of a Hong Kong Department of Health warning. Seems SoloSlim® is contaminated with a sibutramine-related chemical (sibutramine is a prescription weight loss drug). Not good.
2) Next, SoloSlim® claims its single-capsule dosage is enough to provide dramatic results and last you through an entire day. The problem here is that the medicinal plants, food compounds and herbs that are typically found in weight loss products are much like pharmaceutical drugs; they need to be present in a potent enough dosage to have any effect.
Advertising your product as a "once-a-day, single-capsule" solution to weight loss may sound convenient, but in reality, you are all but ensuring most ingredients simply cannot be present in doses high enough to have any effect.
As an example...
The SoloSlim formulation contains glucomannan, which in essence is a fiber supplement. The good news is that there is some real, clinical evidence that indicates it may be helpful for weight loss. However, it needs to be taken in substantial amounts—the study I just referenced, for example, uses 1 gram of glucomannan 3 times daily, prior to meals.
That's the equivalent of 6 rather large, 500 mg capsules.
Uh-huh.
So we can be pretty darn sure that SoloSlim contains nowhere near the amount of glucomannan shown to be helpful in the various clinical studies. If it did, a single capsule would be too large to swallow.
3) Although the ingredients are revealed, just how much of each is included in the formula is not.
It is therefore impossible to determine if any of the ingredients are present in a dosage strong enough to elicit any effect. Basically, it makes it next to impossible to truly assess the value of this formula.
To be fair, most ingredients in this formula do not need to be present in as large a dose as the glucomannan. That said, most of the ingredients have relatively little supporting data behind them... at any dose. Here's a brief breakdown of some of the more promising remaining ingredients...
Citrus aurantium (standardized for synephrine): Once thought to be a credible alternative to ephedra, studies have shown synephrine to be spectacularly "unspectacular" for weight loss. Fucoxanthin: The good news is there is a small amount of promising evidence that indicates Fucoxanthin is useful for weight loss (see Biochem Biophys Res Commun. 2005 Jul 1;332(2):392-7, Asia Pac J Clin Nutr. 2008;17 Suppl 1:196-9). The bad news is that to date, any published material has been based on animal studies. Additionally, there's the problem of low bioavailability of these compounds in humans. This study (see Br J Nutr. 2008 Aug;100(2):273-7) concluded..."... results indicated that the plasma response to dietary epoxyxanthophylls was very low in humans even after 1-week intake of epoxyxanthophyll-rich diets."L–Carnitine Tartrate: Used in fat burners almost forever, l-carnitine, even when used at extremely high doses—much higher than present here—shows relatively little weight loss effect. And the special "tartrate" version? There's no evidence it's any more (or less for that matter) effective than the regular stuff for weight loss. Decaffeinated green tea (standardized for EGCG): Green and tea and one of its critical components, epigallocatechin gallate (EGCG for short) are one of the few bright lights in the natural weight loss supplement world. And while studies have shown that EGCG is beneficial to dieters, it really needs to be combined with caffeine and the other catechins naturally present in green tea to offer the greatest fat burning benefits (Journal of the American College of Nutrition, Vol. 26, No. 4, 396S-402S).In other words, this formula would benefit more from caffeinated green tea. The web site advertising boasts about the "stimulant free" nature of SoloSlim® (i.e., no caffeine, no ephedra), but that boast "rings" a little hollow, given the inclusion of synephrine in this formula—it's an ingredient with well-established stimulant properties (see Ann Pharmacother. 2006 Jan;40(1):53-7. Epub 2005 Nov 29).
At $39.99 per bottle, you're really not getting a heck of a lot of value for your money. For much less, you could buy a better formulated product, or a potent dose of the more promising ingredients—like glucomannan and green tea, for instance. Remember—the convenience of a single daily dose may sound appealing, but it virtually guarantees the majority of ingredients are not present in doses high enough to be helpful.
Give this one a miss.
