Assume that GCETM listed on the bottle is actually GCE ( Green Coffee Extract). GCETM plus all other enzymes are only 410 mg per container of 60 capsules. It does not list how much actually GCETM is among those 410 mg.
Excerpt from one publication.
"overall results demonstrated that GCE administration did not result in any significant alteration in insulin levels (WMD: −0.925 μU/ml, 95% CI:−1.915, 0.064), with significant heterogeneity found across studies (I2 = 87.9%). The results of present study support the use of GCE for the enhancement of blood glucose, while subgroup analysis highlighted significant improvements in insulin levels when GCE is supplemented in doses ≥400 mg/day."

Chlorogenic Acids
Chlorogenic acid is a trivial name used to define the major phenolic components found in coffee. This name originates from early observations that green coffee extracts produced a green color after addition of a solution of ferric chloride. In fact, chlorogenic acids present in coffee are mainly esters of quinic acid with caffeic, ferulic, or coumaric acids. Significant amounts of three isomers (in positions 3, 4, and 5 of quinic acid) of each of these groups of caffeoylquinic, di-caffeoylquinic, and feruloylquinic acids are usually found in green and processed coffees. They are not resistant to heat and are degraded during roasting, contributing to the aroma fraction. Consequently, their levels in the coffee beverage are dependent on the roasting degree, with less than 10% of the original green coffee content found in very dark roasted coffees (Table 3).

Buy decaf instant coffee

Just to keep the record straight, I'll point o ut that the 410 mg of "supplements" is per each capsule and not for the whole bottle of 60 pills. I do agree that not paying for such expensive supplements that probably do not do anything helpful to our bodies is the best route to go. --Richard
