More about this report

Weight loss supplements contain an array of ingredients -- some supported by clinical evidence and some not.  What's more, the quantity and quality of these ingredients varies widely across brands.  To make sense of it all and find the best quality products, ConsumerLab.com reviewed and summarized the evidence behind each of the common weight loss ingredients and many popular formulas.  Just as important, in this report we tested products containing 7-keto DHEA as well as popular herbal blends. (See our reports on other supplements used for weight loss: Chromium, Garcinia cambogia, Green Coffee Bean, and Green Tea, as well as information about Raspberry Ketone).  

What did we find? Three 7-keto DHEA supplements met our quality requirements -- two of which cost about half the price of the third. Among herbal stimulant blends, none could be approved due to concerns over potential side effects for certain people from high amounts of caffeine. A daily suggested serving of one of the products, for example, contained the an amount of caffeine equivalent 15 cans of cola!  Some also included ingredients like bitter orange and yohimbe which, as we explain in the research report on weight loss supplements, should give you pause.
