I just looked at Metabolife’s website, and, in my opinion it’s pretty much a bunch of vague feelgood hype.
Ephedra, as a whole herb, has value in the herbal pharmacopeia, especially as an aid to asthmatic complaints. But it is horribly misused as a stimulant. There has been an ongoing (five year) FDA process in how we are going to deal with that misuse.
As an aid to weight loss, yup; ephedra and caffeine will certainly stimulate you, producing a “thermogenic” effect. But most modern folks are already chronically overstimulated, with stress, sugar, and caffeine. If you expect this pill to solve the problem of poor diet, insult is heaped upon injury. The over-stimulation will eventually wear your poor body out. The better approach is to NOT add more stimulation, but to support yourself through better nutrition. Over-stimulation only encourages binges to support the body when it crashes.
The Metabolife site, unless I missed something, offers no worthwhile education about the substances it promotes. That’s an alarm bell right there. And the price, according to Stupendous Man’s 3rd link; the American Health Consultants; ($35-50 for 90 tabs), just boggles my mind. In my opinion, that’s way too much, and preying on people in dire need of a quick solution to a troublesome problem.
It galls me too, as one who studies herbal medicine seriously, and thoughtfully, that companies like this end up muddying the waters for all. Their misuse of an herbal substance, and the consequent harsh judgement, puts people in an uneccessarily alarmed state about the efficacy and safety of herbal medicines in general.
There are ways to support your body with herbal medicine during the time you want to lose weight, but, IMHO, this isn’t the way to do it.
