things people ask
Honest answers, even the awkward ones.
Is there caffeine in COJO?
No. COJO is designed to ride alongside the caffeine you already drink, not add to it. The L-theanine softens the spike of your existing coffee — pairs best with your first cortado of the day.
How many chews a day?
One per coffee, up to four a day. Most people land at two — one with the morning espresso, one with the afternoon pick-me-up.
Can I chew if I'm pregnant or breastfeeding?
L-theanine and the doses we use are within recognised safe limits, but every body is different. We always recommend running it past your GP first.
What does it actually taste like?
Clean spearmint. Not the cloying minty-toothpaste kind — closer to a fresh herb. Sweetened with xylitol so it doesn't go syrupy.
How fast does it kick in?
Most people feel the effect within 20–30 minutes of chewing — about the same time their espresso is hitting. The window of "smooth focus" sits across the next 1–2 hours.
