What is GCA®?
GCA® Green Coffee Bean Extract, manufactured by Applied Food Sciences, is one of the few patented forms of green coffee bean extract. Green coffee beans are beans that not have not yet been roasted, as this reduces the levels of chlorogenic acids. These are naturally occurring antioxidants contained in coffee beans that have been studied for their effects on weight loss.* Some studies have shown a positive correlation to chlorogenic acids and the maintenance of blood sugar levels in the body. There is also preliminary evidence suggesting a potential link to slowing the production of body fat.*
What makes GCA® so unique is its processing technique for extracting chlorogenic acids from green coffee beans. This brand has proven to consistently yield industry-leading quality, concentration, and safety standards for green coffee bean extract.
What is the difference between NatureWise UltraPure GCA® and NatureWise Green Coffee Bean Extract 800?
NatureWise UltraPure GCA is formulated to be dosed three times daily. NatureWise Green Coffee Bean Extract 800 is formulated for twice daily dosing. Both formulas are standardized to 50% chlorogenic acids, the compound studied for its potential weight-loss effect.
