If you’ve been shopping for kratom lately, you’ve seen the letters 7-OH everywhere. 7-Hydroxymitragynine is the most potent alkaloid found in the kratom plant — and it’s the reason modern products like Rapture’s the 100mg MIT can cans can deliver precise effects in a single small can.
What Exactly Is 7-Hydroxymitragynine?
Kratom leaves contain more than 40 alkaloids. Two dominate: mitragynine, which makes up roughly 1–2% of dried leaf, and 7-hydroxymitragynine, which occurs naturally in tiny amounts — but binds to opioid receptors with far greater affinity. That’s why 7-OH products are measured in milligrams while plain leaf powder is measured in grams.

How Is 7-OH Made Into Cans?
Manufacturers extract the alkaloid fraction from kratom leaf, purify it, and press it into single-serve cans with food-grade binders. The result is what you find at Rapture’s can shop: consistent, verifiable, portable servings.
How Strong Is It, Really?
A standard kratom powder serving is 2–4 grams. Rapture’s line starts at 55mg and tops out at 175mg — a spread that suits everyone from total beginners to veteran users. Potency per milligram is why we call 7-OH “concentrated kratom.”
How Beginners Should Start
Follow the same advice we give in our full dosing guide:
- Begin with a 55mg starter can — or half of one.
- Wait 60–90 minutes before deciding whether to take more.
- Never take a second serving within 4 hours.
- Keep your first week to one serving per day.
Safety First
7-OH is powerful, and it deserves respect. Don’t combine it with alcohol or sedatives, don’t drive until you know your response, and avoid it if you’re pregnant or nursing. Visit the FAQ library for more, and read our responsible use guide.
