"It's a two-ingredient supplement combining caffeine (a stimulant) and L-theanine (a calming amino acid from tea) — a well-studied combo for clean, focused energy."
Consumer advice
1. **Check the label for doses before buying**: The effective combo is typically 100–200mg caffeine paired with 200mg L-theanine. If the capsule doesn't specify this, you can't verify you're getting a therapeutic amount. 2. **Compare prices**: This is a commodity ingredient stack. Check Bulk Nutrients, iHerb, or Amazon AU for the same ingredients — you may find better value. 3. **Avoid if caffeine-sensitive**: Even with L-theanine, this product contains caffeine. Don't take it in the afternoon if you're sensitive to sleep disruption. 4. **This is one of the few supplement combos with genuine evidence** — if the dose checks out, it's a reasonable purchase for focus and energy without the crash of caffeine alone.
