Quick answer
Green tea extract is a concentrated form of green tea standardized for catechins, especially EGCG, which are studied for antioxidant and metabolism support. It also contains some caffeine, which contributes to its mild energy effect.
Key takeaways
- EGCG is green tea's key catechin.
- Studied for metabolism and antioxidants.
- Contains some natural caffeine.
- Support, not a weight or sugar cure.
What EGCG is
EGCG is the most abundant catechin in green tea, researched for antioxidant and modest metabolic support. The NCCIH has a balanced overview.
The caffeine note
Green tea extract carries caffeine, which aids alertness but matters if you're sensitive or already consuming guarana or coffee.
Why it's in the formula
Green tea rounds out Glyco Defender for metabolism and energy support. Its effects are modest — honest support, not a dramatic fat-burner.
A note on scope. This is general education for healthy adults, not medical advice, and no supplement is a treatment for diabetes, prediabetes or any condition. Healthy blood sugar comes from diet, activity, sleep and, where needed, medical care; a supplement can only support those. Glyco Defender is for adults 18+ — talk to a doctor before starting a supplement or changing anything about how you manage blood sugar, especially if you take medication, are pregnant or nursing, or have a condition. Never start, stop or change medication on your own.
