1, Green coffee bean extract

Potency: 5 stars

Safety: 5 stars

Recommendation: 5 stars

best weight loss supplements -green coffee beanGreen coffee bean can be roasted as coffee, if we used it for extract supplement, then the major compound named as chlorogenic acids – CGAs showed effects for weight loss in two small studies. The studies used branded green coffee bean extract for 12 weeks, and showed a significant weight loss about 2 lbs more per month than those received placebo among the overweight individuals. Additional, there was a short term study from Dr. Oz show among 100 women consumed with green coffee extract versus placebo, it showed 2 lbs weight loss among those taking green coffee extract while 1 lb loss who was taking placebo, reported after two weeks.

No side effect reported from short term clinical studies. But as it impacts blood sugar level and blood pressure level, people with those concerns should be careful before consume it.

Recommendation:

Garden of Life FucoThin Green

GNC Total Lean™ Advanced Metabolic Elite™ – GNC doesn’t has pure green coffee bean product, this weight loss supplement contains 200mg green coffee bean extract.

Also above two weight loss supplements have been approved by Consumerlab for their purity in green coffee bean reviews.

Other weight loss supplements, such as Raspberry ketone, DHEA, etc. are not well studied as of now, or only tested on mice but not among people. So we cannot list them in our top 10 best weight loss supplements with limited evidence. Hopefully, we will update this list if we have more clinical study and evidence to support their efficacy.
