Have anyone used either of these products? I can't find any info saying that they are unsafe, so I am wonderng if they are worth a shot.

What are they used for?

I have taken both. I currently have Svetol from Swanson vitamins but I do not feel and have not seen any appreciable anything from it. I have a girlfriend who is very sensitive to caffeine who can only take a small amount and it has kept her lean when she was going through a lot of stress (she is low BF to start). Also, Starbucks now has their "Refreshers" drinks that have it. It is supposed to be a great antioxidant, too.
I have also taken raspberry ketones but mixed with other fat loss agents. It has been around for quite some time and I am kind of proud to say that I know some of the guys that broke this into the supplement industry. It had been around for at least 5 years, if not longer. BSN Atrophex contains it and that is my going out pill. About 30 minutes after taking it I can actually feel a total sense of happiness come over me. It is weird but I can seriously feel when it kicks in. It makes me much more socialable and dampens the effect of alcohol on me. I have not tried it for weight loss….wait, maybe I did but about 10 days in I started getting ansy.
I can try and dig up some information about them.

This was the study from back in 2005 that prompted a possibiliry. Back in 2005 ephedrine was still available so it was not that big of a deal. Seeing as ECl is not easily available in the states and that the FDA is going after those that have geranamine (1,3 dimethylamylamine), RK is gaining in popularity again.
I will say that I get raspberry burps (similar to fish oil burps but much more pleasant). Also, as a TMI, there was a company that had made a lube that was silicone and RK's that was amazing. They sold it as a lube and as a massage oil. As a topical it brings more blood to the surface making those areas much more sensitive. I will just leave it there.
For about 2 years they were hard to come by but it looks as if there are lots of sources now.

Interesting. I kinda figured about the raspberry burps. I could handle that. It gives you a euphoria? That sounds odd. Maybe when I can justify the expense I will try them.

I just realized that I never linked the study….duh. Atrophex in general, not just the raspberry ketones. It has a blend of "mood and mental optimizers". http://www.bsnonline.net/details/atrophex.html
I am on a really really really slow internet connection at a campground so I can't even find the link right now. I will try when we get back home.

I heard that aswell as being an anti-oxidant like someone already suggested, they are an appetite surpressant, so will stop you craving so much food if you are cutting down on your meals. I did a search and found this site which looks to avoid the hype and covers them in more detail. http://raspberryketonesreviews.org
Let me know how you get on. 🙂

This is the abstract from the published research from 2005:

Abstract
Raspberry ketone (4-(4-hydroxyphenyl) butan-2-one; RK) is a major aromatic compound of red raspberry (Rubus idaeus). The structure of RK is similar to the structures of capsaicin and synephrine, compounds known to exert anti-obese actions and alter the lipid metabolism. The present study was performed to clarify whether RK helps prevent obesity and activate lipid metabolism in rodents. To test the effect on obesity, our group designed the following in vivo experiments: 1) mice were fed a high-fat diet including 0.5, 1, or 2% of RK for 10 weeks; 2) mice were given a high-fat diet for 6 weeks and subsequently fed the same high-fat diet containing 1% RK for the next 5 weeks. RK prevented the high-fat-diet-induced elevations in body weight and the weights of the liver and visceral adipose tissues (epididymal, retroperitoneal, and mesenteric). RK also decreased these weights and hepatic triacylglycerol content after they had been increased by a high-fat diet. RK significantly increased norepinephrine-induced lipolysis associated with the translocation of hormone-sensitive lipase from the cytosol to lipid droplets in rat epididymal fat cells. In conclusion, RK prevents and improves obesity and fatty liver. These effects appear to stem from the action of RK in altering the lipid metabolism, or more specifically, in increasing norepinephrine-induced lipolysis in white adipocytes.

That sounds pretty neat. I may try it after a little while. Couldn't hurt. It's probably like me taking my daily cranberry pill.

Green coffee extract is actually being used in my work (Starbucks) for their new line of drinks, called "Refreshers." Basically, it's got more caffeine than a can of pop in one Tall one, so it'll get you going pretty good… doesn't taste like coffee, and all that.
That's really all I've heard about it, and all I've heard it's good for.

I have been taking raspberry ketones for about 7 months and I love it, it kills my appetite, gives me a general feel good mood and lowers my blood sugar levels, I feel it is a big part of my weight loss success.

Just wondering what brand you are taking…
-
When it comes to supplements, Swanson, NOW and Source Naturals are probably some of the best manufacturers out there. Swansons Razberi K is only $3.79 for 60 pills of 100 mg and you can generally find discount codes for them. I try to stay away from any of the "fad" manufacturers.

I was wondering the same thing. I read somewhere that some companies are putting EPHEDRA is their rasp ketones. WTF!?
-
Ephedrine is still safe when taken properly (and is still legal outside of the US). You have an issue when people start taking mass quantities of it. Not much different than downing a bunch of red bulls.

I'd still rather not take the risj. Heart problems run in my family.
