You've Got questions...
WE HAVE ANSWERS
Will Oka Matcha give me enough energy to replace my coffee?
Will Oka Matcha give me enough energy to replace my coffee?
Absolutely. Oka uses ceremonial grade matcha which contains natural caffeine, but unlike coffee, it's released slowly alongside L-theanine.
Meaning you get hours of smooth, steady energy without the spike and crash. Most customers notice the difference within the first 2–3 days.
I've tried matcha before and hated the taste will this be different?
I've tried matcha before and hated the taste will this be different?
Most matcha tastes grassy and bitter because it's low grade powder. Oka uses ceremonial grade matcha the highest quality available.
Which has a naturally smooth, slightly sweet flavour. Mixed with your favourite milk it tastes like a proper café latte, not a health supplement.
What makes Oka different from other matcha brands?
What makes Oka different from other matcha brands?
Most matcha products are just matcha, full stop. Oka is a fully dosed functional blend combining ceremonial matcha with King Trumpet mushroom extract, electrolytes, allulose, and Methyl B12.
Every ingredient has a specific job: breaking the cortisol-coffee cycle, supporting your gut, rehydrating your body and restoring what chronic stress depletes.
No other matcha on the market does all of this in one scoop.
Does matcha have less caffeine than coffee?
Does matcha have less caffeine than coffee?
Matcha contains less caffeine than coffee — but that's actually the point. Coffee floods your system with caffeine all at once, spiking cortisol and setting you up for a crash.
Matcha delivers caffeine slowly and steadily alongside L-theanine, which calms the nervous system at the same time. The result is focused, jitter-free energy that lasts — without the anxiety, racing heart or 2pm slump that coffee causes.
How long until I feel results?
How long until I feel results?
Most customers report feeling a difference within 3–5 days. Smoother energy and fewer jitters tend to come first.
Followed by reduced bloating and improved focus by the end of the first week. Cortisol and stress improvements are typically noticeable by days 10–14.
Is it easy to make?
Is it easy to make?
Incredibly easy. One scoop, hot or cold water or milk, stir or froth — done in 60 seconds.
No blender, no complicated recipe, no barista required. It fits into your existing morning routine without adding any extra steps.
Are there any artificial sweeteners?
Are there any artificial sweeteners?
None. Oka uses allulose — a naturally occurring sweetener that provides a gentle sweetness without spiking blood sugar, disrupting gut bacteria or adding empty calories. Nothing artificial, ever.
What if I'm sensitive to caffeine?
What if I'm sensitive to caffeine?
Oka is a great option for caffeine-sensitive people. Because the caffeine is released slowly alongside L-theanine.
Most people who can't tolerate coffee find they handle Oka Matcha comfortably. That said, if you have a diagnosed caffeine sensitivity we recommend starting with half a scoop to see how your body responds.
Can I drink it hot and cold?
Can I drink it hot and cold?
Yes — Oka works beautifully both ways. Hot with oat milk for a cosy morning latte, or blended over ice for a refreshing afternoon drink. Either way, you get the full benefit of every ingredient.
What if I don't like it?
What if I don't like it?
Then you don't pay. We offer a 30-day money back guarantee — no questions asked.
If you don't feel the difference in your energy, bloating or focus, reach out and we'll refund you in full. Simple as that.
