What to expect

Early

Days 1–7

First days to weeks: any focus or energy lift comes from caffeine content and is felt acutely; antioxidant effects are not something you feel.

Mid

Weeks 2–4

Weeks 4-8: metabolic and antioxidant support accrues with consistent daily use alongside diet and activity.

Later

Weeks 4–12

Ongoing: a long-game supportive supplement; benefits are maintenance-oriented rather than escalating.
