Each capsule delivers 400 mg of **green tea leaf extract** standardized to 80% total catechins, yielding 200 mg of **EGCG** (epigallocatechin gallate), the most researched catechin in green tea. Multiple meta-analyses support EGCG for modest reductions in LDL cholesterol and total cholesterol, along with potent antioxidant activity. At 200 mg EGCG per capsule, you're at the entry point of the clinically studied range (200-500 mg), so one capsule gets you started but two would bring you closer to the doses used in cardiovascular and metabolic research.

The extract is nearly caffeine-free at just 4 mg per capsule, roughly one-thirtieth of a cup of coffee. This makes it practical if you're sensitive to caffeine or taking it later in the day. An additional 50 mg of **decaffeinated green tea** adds extra polyphenols beyond the standardized EGCG content. The veg capsule shell keeps the product suitable for plant-based diets.

One important safety detail: the European Food Safety Authority sets a precautionary ceiling of 800 mg EGCG per day from supplements due to rare reports of liver stress. At 200 mg per capsule, you have wide margin below that threshold even at two capsules daily. Always take green tea extract with food, as the label directs, since fasted use is linked to the majority of reported liver-related side effects.
