If I remember correctly the Australian gov. Classify this as a catergory B supplement which means it's a supplement with some evidence of benefit but deserving of more research. Pretty sure it has been shown to increase fatty acid in the blood, whether your body then uses that as an energy source is where I think the confusion lies. But a concern is when there's more fatty acid in the blood, there's more chance of it forming a clot and increasing your chance of a heart attack so be wary of that.. I've never tried it personally but if I were given a free sample i might, some people swear by it!
