What It Actually Is
Green tea extract is concentrated from Camellia sinensis leaves, rich in catechins and containing a small amount of natural caffeine.
What Research Generally Shows
Green tea catechins have a substantial research base for supporting metabolism and general antioxidant activity.
The Honest Gap
HorseBoost doesn't disclose the specific amount of Green Tea Extract included, or how much of the label's disclosed 5mg caffeine (if any) comes from this ingredient versus being added separately.
