After some research I found this information of the Nutrie Skinné ingredients from pretty good (not great) sources
chromium picolinate
http://www.vanderbilt.edu/AnS/psychology/health_psychology/chromiumpicolinate.htm
"Despite rampant claims that chromium picolinate is a weight loss miracle that will melt fat, improve metabolism, and increase muscle mass, scientific evidence overwhelmingly indicates that the supplement does nothing of the kind. When combined with exercise, chromium supplementation does nothing to enhance weight loss as compared to exercise alone, in study after study. The case of chromium picolinate should caution consumers against believing miracle weight loss claims."
"These diet compounds, which are readily available over the internet, often combine chromium picolinate with L-carnitine, with guarana and ma huang, or with dangerous diuretics. Such combination tablets are risky, as any interactions between chromium picolinate and other supplements remain unknown at this time"

"More and more studies are showing that chromium picolinate's negative effects are quite drastic. Two reputable studies have shown that it can trigger mutations in DNA as a result of reactions with other elements found in the body [source: Women Fitness]. These elemental reactions have an adverse effect on DNA, which may cause cancer [source: UC Berkeley Wellness Letter]. Other, less severe reactions may result from the dangerous compounds created from these elements. In addition, since picolinate isn't found naturally occurring with chromium, the picolinate may eventually break apart from the chromium and have negative effects [source: Women Fitness]."
"Fitting with the FTC's complaint against the three California companies marketing chromium picolinate, scientific research has not been able to support the claims that chromium picolinate helps people lose weight. Several studies conducted during the late 1990s, when chromium picolinate really started to soar in popularity, indicate that chromium picolinate does not contribute to more lean muscle or decreased fat in the body [source: Allen]."
Garcinia
http://www.webmd.com/vitamins-suppl...ngredientId=818&activeIngredientName=GARCINIA
"Developing research suggests that garcinia might prevent fat storage and control appetite; however, whether these effects occur in humans is unclear."
"Taking garcinia fruit rind extract doesn't seem to decrease weight, fat breakdown, or energy expenditure in overweight people. There is some mixed evidence that garcinia might help people feel full even when eating less, but it's too early to recommend garcinia for this use."
"Garcinia is POSSIBLY SAFE for most people when used for 12 weeks or less. Long-term safety is unknown. Garcinia can cause nausea, digestive tract discomfort, and headache."
http://www.ncbi.nlm.nih.gov/pubmed/22530711
"Although several studies have found that the administration of G. cambogia extracts is associated with body weight and fat loss in both experimental animals and humans, we should be cautious when interpreting the results as other randomized, placebo-controlled clinical trials have not reported the same outcomes. Furthermore, most studies in humans have been conducted on small samples and mainly in the short term. None of them have shown whether these effects persist beyond 12 weeks of intervention. Therefore, there is still little evidence to support the potential effectiveness and long-term benefits of G. cambogia extracts"
http://www.med.nyu.edu/content?ChunkIID=21727/
"Although animal and test tube studies as well as two human trials suggest that HCA might encourage weight loss , other studies have found no benefit"
"A 12-week double-blind trial of 89 individuals found that HCA had no effect on appetite. 18 Another study tested HCA to see if it could cause weight loss by altering metabolism, but no effects on metabolism were found."
Rhodiola
http://www.med.nyu.edu/content?ChunkIID=111798
"One small double-blind trial performed in Belgium did find evidence that use of a different rhodiola extract at a dose of 200 mg 1 hour before endurance exercise may improve performance. 5 However, another study failed to find benefit with a combination of cordyceps and rhodiola."
http://en.wikipedia.org/wiki/Rhodiola_rosea
"Two systematic reviews on R. rosea extracts concluded that the research evidence is contradictory, and definite conclusions over its efficacy to relieve mental and physical fatigue are hampered by the lack of rigorously-designed, well-controlled randomized control trials"
Conjugated linoleic acid
http://www.webmd.com/vitamins-suppl...activeIngredientName=CONJUGATED LINOLEIC ACID"Conjugated linoleic acid might help decrease body fat, but it does not seem to decrease body weight."
http://www.bodybuilding.com/fun/mike8.htm
"Swedish researchers reported in December, 2000 that CLA takes away fat while increasing muscle mass. The study found that approximately 3.4 grams of CLA per day is the level needed to obtain the beneficial effects of CLA on body fat" (skinny only has 500mg)
http://en.wikipedia.org/wiki/Conjugated_linoleic_acid
"Some studies have found no significant effects of CLA supplementation on fat mass loss"
Raspberry Ketones
http://www.huffingtonpost.com/becky-hand/raspberry-ketones_b_2727943.html
"Raspberry ketones have never been tested on humans in scientific studies."
http://www.webmd.com/vitamins-suppl...Id=1262&activeIngredientName=RASPBERRY KETONE
"Raspberry ketone became popular for weight loss after it was mentioned on the Dr. Oz television show during the segment called “Raspberry ketone: Miracle fat-burner in a bottle” in February 2012. Even though it is touted as a “miracle” for weight loss, there is no reliable scientific evidence that it works for improving weight loss."
Guarana
http://www.webmd.com/vitamins-and-supplements/lifestyle-guide-11/supplement-guide-guarana
"Researchers once believed that the active ingredient of guarana was a chemical specific to the plant -- guaranine. But they later discovered that it was just caffeine. Guarana has among the highest concentrations of caffeine in any plant. It may contain up to 3.6% to 5.8% caffeine by weight. Coffee only has up to 2%."
"High doses of caffeine may raise the risk of increased heart rate, breast disease, and high blood pressure. An overdose of caffeine can cause seizures and convulsions. Talk to your doctor before using guarana if you have high blood pressure, anxiety disorders, glaucoma, osteoporosis, heart problems, bleeding disorders, diabetes, kidney problems, or liver disease. At least one death has been reported in a young woman with mitral valve prolapse who consumed a guarana containing drink. People with MVP should speak to their doctor before using guarana."
"There’s some evidence that guarana – when used along with other supplements – may promote weight loss. It’s uncertain if the guarana specifically was responsible."
