We look behind the glitz and glamour and see what Xenadrine is all about. Is it a case of style over substance or can it really be the answer to our weight loss problems. Let’s take a look shall we?
First stop is to the main website, where by the looks of it there are 4 products available. Let’s quickly take a look at each of these and see what they are claiming to do.
The main flagship product (product image above), which simply bears the name Xenadrine. The tag line is “Maximum Energy! Powerful Weight Loss” and is said to have “Clinically proven key weight loss ingredients, thanks to the new Xenadrine.”
All fairly non-descript stuff, so what are the magic ingredients? Well they have kindly supplied the ingredients from the label:
Hold on a minute, haven’t we seen this sort of blend before? That is virtually the exact same composition as Hydroxycut, another discredited diet pill we reviewed here.
More on this later but it looks like it’s the same people behind both products.
There is very little evidence to what Xenadrine can do exactly; all the main claims are in relation to the ingredients. The extreme energy claim refers to the fact it contains caffeine.
We suspect it is virtually the same formula (lady’s mantle extract, wild olive extract, komijn extract and wild mint extract) as the standard Xenadrine, but in a pack of 21 sachets for convenience.
However, there is no indication at all what the composition is so this is just a pure guess on our part. All the claims relate to the ingredients in this mix, but again without telling us exactly what they are anywhere, it is hard to decide if the claims are true or not.
The same formula as the regular Xenadrine but with the caffeine removed, as a result the claims for “extreme energy” do not appear for this product.
As with the other products, there are no claims that the product itself will do anything, but that the ingredients in the mix are clinically proven to work. It also claims to have been a reliable brand for years.
As you might guess this is supposedly the extreme version of Xenadrine, and even has its own dedicated website. It seems to be targeted more towards bodybuilders and sportsmen and people heavily into fitness.
The ingredients seem to be different from the other products.
This time there is much more caffeine included, as well as Green Coffee extract 200mg, Sage leaf 150mg, L-theanine 100mg, Yohimbe 56.3mg and Rhodola root 50mg.
Here is the Xenadrin Xtreme supplement facts label:
All the claims for this product are based around the caffeine content, which has been shown to boost energy.
That is basically all it does, gives you an energy kick from the high caffeine content. They use some buzzwords like “supercharged” and “thermogenic furnace” when in actual fact is the same as consuming some string coffee.
The main Xenadrine products don’t actually make any claims at all that they will help you lose weight. This is because legally they are not allowed to do so; instead they claim that the ingredients have been proven to help lose weight.
These are the same ones used throughout: Lady’s mantle extract, wild olive extract, komijn extract and wild mint extract. Unfortunately that is all the information that is given by the manufacturers.
These particular ingredients refer to a study that showed they could be effective for weight loss:
This was a study undertaken in Israel in 2010 and was studied as these herbs were traditionally used in Greco-Arab and Islamic medicine. The exact composition of the test ingredients was:
The present study evaluated Weighlevel, a combination of four herbal remedies that are traditionally known for their weight reduction effects. The Weighlevel combination contained 60mg Alchemilla vulgaris L., 50mg Olea europaea L., 20mg Mentha longiforia L, 25mg Cuminum cyminum L., 7mg Vitamin C, and 148mg Tricalcium phosphate (TCP).
So this would give us the following:
Crucially this adds up to 310mg per tablet.
In the study the subjects were told to take 1 tablet before each meal 3 times per day (total of 3 tablets per day).
This gives a total of 930mg per day of the formula to be effective for weight loss.
Unfortunately….None of the Xenadrine products appear to include enough of the active ingredients!!!
They are deliberately secretive about what is exactly in each product, precisely because there aren’t enough of the ingredients included, to be effective for weight loss.
At first glance it appears that Xenadrine might include some good ingredients that have been shown to work for weight loss.
But the main problem is that Xenadrine are not indicating precisely how much of any of these ingredients are contained in the product. By using a proprietary blend it is not possible to see exactly what you are taking.
Never buy or consume a product where there is no indication of what is in it!
As these are high caffeine blends then anyone susceptible to the effects of high caffeine consumption may experience side effects.
Previous versions of Xenadrine have been outright banned by the FDA.
There are a number of “success stories” on the main website, that all look highly suspicious. The pictures themselves look like they have been airbrushed to make the weight loss before and after pictures look even more impressive. It is also worth noting that they have in very small writing under each “story” the following disclaimer:
Individual used Xenadrine with diet and exercise and was remunerated. Average weight loss with key ingredients was approximately 21 lbs. vs. 2 lbs. for placebo in one 12-week study, and approximately 17 lbs. vs. 2 lbs. in one 8-week study. All groups followed a calorie-reduced diet.
The important thing to note here is they were paid to take Xenadrine and had a carefully controlled diet and exercise plan.
Well the testimonial says it does, but as we have shown, is it possible to believe these?
There’s no indication what is in Xenadrine and in what quantity, so it is impossible to say one way or the other.
The clinical studies referenced all over the main website, show that a certain quantity of ingredients in a specific combination is required in order to be effective. Unfortunately it doesn’t look like this amount is included in any of the variations of the products. The makers of Xenadrine are extremely careful about what they say.
There is no direct claim that you will lose weight from taking Xenadrine!
Xenadrine can be bought online direct from the main merchant, as well as a whole host of outlets.
Be aware that taking Xenadrine at the recommended dose would cost in the region of $90 per month.
This is where it gets really interesting, as the whole Xenadrine brand has got a very poor history.
NOTE: It is worth noting that the present owners of Xenadrine, Kerr Investment Holding Corp. bought the product after the FTC had previously banned it. The first owners were Nutriquest Inc.
Xenadrine first hit the headlines in 2005 when the FTC decided to take action against the owners.
The Federal Trade Commission has filed a federal district court complaint charging Robert Chinery, Jr., Tracy Chinery, and their company, RTC Research & Development, LLC (the Chinery defendants) with making misleading weight loss claims for the popular dietary supplement Xenadrine EFX.
As a result of this they were find a massive $25 Million in early 2007 to settle the claims made by the FTC. http://www.ftc.gov/opa/2007/01/weightloss.shtm
It was shortly after this that a deal was struck to offload the trademark names to the present owners. They then went about reformulating the ingredients to come up with the ones you see today.
So you would think that everything would be fine then, however if you read our in depth investigation into one of the other product lines owned by these guys you will see that it’s not that straightforward.
You can read more about the (new) owners of Xenadrine HERE.
Despite it being one of the better-known diet pills and supplement on the market, Xenadrine also seems to have a dismal track record. With big fines from the FTC imposed on both the old and new owners it doesn’t exactly inspire much confidence!
The claims behind the “new” version are pretty empty, and do not seem to stack up.
Also the paid testimonials look highly dubious, despite this being one of the strongest claims behind the product. The FTC said that previously people had been paid between $1000 and $20,000 to lose weight and provide a testimonial!
For these reasons we reject Xenadrine diet pills.
