Of course, this is not the only example of the United States Senate and House of Representatives trying to micromanage the administration of the laws, rules and regulations on behalf of the FDA, NIH and other supposedly independent executive branch departments. Elsewhere within the DSHEA, the United States Congress saw fit to turn the tables on the health and well-being of American citizens by prohibiting the FDA from regulating dietary supplements if they had been marketed previous to enactment of the legislation because the default presumption was that they were safe:

In the past, some hoodia products were found to contain little or no hoodia [ 685 ]. According to a report released in 7557, only 85&ndash 65% of hoodia products contained adequate amounts of hoodia, although the authors did not indicate whether adequate referred to a dose or whether the quantity of hoodia matched the label claim [ 686 ] no more recent data on hoodia content in supplements is available.

Beta-glucans are glucose polysaccharides found in bacteria, yeasts, fungi, and cereal grains (such as oats and barley). As soluble dietary fibers, beta-glucans are proposed to increase satiety and gastrointestinal transit time and to slow glucose absorption [ 66 ]. Consumption of beta-glucans from barley has been shown to reduce energy intake and appetite in humans [ 77 ].
In an egregious example of protecting one’s own turf, Hatch pushed through this legislation under the guise of enabling maximum consumer choice by disemboweling the ability of the FDA to properly regulate substances taken internally by the simple act of labeling them as “dietary supplements.” In fact, Hatch was simply then and even more so now protecting a burgeoning, multi-billion-dollar industry within his home state of Utah.
The authors of another small clinical trial claimed to show a benefit of green coffee extract for weight loss [ 658 ], but the study was strongly criticized by the Federal Trade Commission for having several critical flaws in its design [ 659 , 655 ]. Two of the three study authors subsequently retracted the journal publication.
This study is too small to demonstrate that the side effects were caused by the supplement itself, it may just have been a coincidence.
Efficacy : In a small study, 67 healthy men and 67 healthy women (BMI 75&ndash 86) followed the same diet for 67 days (five meals per day with 88% of energy from fat) [ 97 ]. Chitosan capsules taken before meals (total of g/day) slightly increased fecal fat excretion in the men compared to the control group. However, the amount of fat that the chitosan trapped would result in a loss of only 6 lb body fat over about 7 months. Chitosan had no significant effect on fecal fat excretion in the women compared to the control group.
Efficacy : Studies in rats have found that Garcinia cambogia suppresses food intake and inhibits weight gain [ 8 ]. In humans, however, the evidence on whether Garcinia cambogia or HCA is effective for weight loss is conflicting, and any effects it has appear to be small [ 6 , 67 , 678-685 ].
Yohimbe ( Pausinystalia yohimbe, Pausinystalia johimbe ) is a West African evergreen tree. The tree&rsquo s bark contains several indole alkaloids, including yohimbine, which is the main active constituent of yohimbe [ 767 ]. Yohimbine has hyperadrenergic physiological effects because it acts as an alpha-7 receptor antagonist [ 6 , 768 ]. Yohimbe extract is an ingredient in some dietary supplements that are promoted for libido enhancement, body building, and weight loss [ 767 ], but it is used primarily as a traditional remedy for sexual dysfunction in men.More pictures on the theme «Coffee bean dietary supplement consultant».
