UC X is a limited edition remix of UC with one deliberate change: mesembrenone pushed from the standard 20 to 25% up to 36% or more of the profile. Mesembrenone with delta mesembrenone is the pairing Ultrakanna credits for kanna’s relaxing side, so UC X is UC with the calm turned up. It was out of stock when we checked.

What UC X Is
Ultrakanna publishes the UC comparison right on the label, which is genuinely helpful: same total alkaloids, same mesembrine floor, but the relaxing alkaloids redistributed toward mesembrenone. The company describes the result as a more relaxing experience than standard UC.
Use cases mirror UC: de-stressing, calming anxious moments, evenings, meditation.
Who It Suits
Ultrakanna’s own use cases:
- De-stressing and calming anxious moments
- Relaxing at the end of the day
- Meditation
How To Take It
The recommended serving is 10 to 20mg; start at the bottom of that range with a milligram scale. Oral, sublingual, or brewed into tea, which trades slower onset for a session of up to two hours.
The standard kanna safety rules apply. Do not combine kanna with antidepressants or other prescription medications, and if you recently stopped such medication, wait several months first. Do not mix kanna with alcohol. Increase doses gradually, no more than 5mg at a time, and wait at least an hour before taking more. This is educational content, not medical advice.
Price And Value
At the time of writing UC X lists at about $34 for 1 gram, a small premium over standard UC (about $33), though it was out of stock when we checked. The multi-unit bundle discount (5% to 15%) applies when available.
Whatever you order, the code heykanna takes 10% off your first purchase. Details on our Ultrakanna discount code page. Ultrakanna also ships free on US orders over $100 and international orders over $300.
Verdict
If UC already suits you and you want a deeper lean into relaxation, UC X is the obvious limited-run experiment. While it is out of stock, standard UC or the Zen Gumdrops cover the same territory.

UC X FAQ
What is the difference between UC and UC X?
Same total alkaloids (5.5% or more) and mesembrine floor (50%), but UC X raises mesembrenone to 36% or more against UC’s 20 to 25%. Ultrakanna describes UC X as the more relaxing of the two.
Is UC X in stock?
It was out of stock when we last checked (July 11, 2026), and it is sold as a limited edition, so availability comes and goes. Standard UC is the fallback.
What is the UC X dose?
Ultrakanna recommends 10 to 20mg per serving, starting low. In tea the session extends to around two hours.
Is UC X good for sleep?
It is the most mesembrenone-forward powder in the range, which is the relaxing end of kanna’s spectrum, and its use cases are evening ones. It is not a sleep aid and we make no medical claims.
