Green coffee extract provides more benefits than roasted coffee.

Research has shown that chlorogenic acids the major compounds present in green coffee are highly absorbed and metabolized in humans (Farah A, et al., 2008).

In the following study coffee extract was found to induced apoptosis (cell death) in a human prostate carcinoma cell line (Bauer D, et al., 2018). The level of roasting reduced this ability.

Green coffee extract has been found to produce several health benefits.

These researchers found a significant reduction in fasting blood glucose, blood insulin and total cholesterol (Asbaghi O, et al., 2020).

Subgroup analysis of the same study also showed a significant reduction in triglycerides and LDL, both cardiovascular risk factors. In this research where 27 studies were reviewed, all of them were randomized placebo controlled trials, green coffee supplementation significantly decreased fasting blood glucose, insulin, triglyceride, and increased HDL, the so called good cholesterol (Morvaridi M, et al., 2020).

If you were to drink green coffee, you would find that it does not taste like roasted coffee. Green coffee is better taken as an extract in supplemental form.
