Mitragynine, often shortened to MIT, is a compound found in the leaves of the kratom tree. Our tonics are made with kratom, so it's a word you'll see on our lab reports. Here's what it is, where it comes from, and what we don't claim about it.

Because they contain kratom, GÜD Tonics are for adults 21 and over only.

What Mitragynine Is

Mitragynine is the main alkaloid in the leaves of Mitragyna speciosa, a tree in the coffee family that grows in Southeast Asia. The leaf is known as kratom. A related compound, 7-hydroxymitragynine (7-OH), shows up in the leaf in much smaller amounts.

The National Institute on Drug Abuse has more on kratom and how researchers are studying it.

Where It Shows Up in GÜD Tonics

Our Baja Bliss, Pink Sunset and TropiColada tonics are made with noble kava root extract and kratom. The mitragynine comes from the kratom. Our Raw Kava Extract Powder is kava only, with no kratom.

Every lot is tested by a third-party lab. The reports list the alkaloids measured, including mitragynine, and you can read each one on our Lab Results page.

What We Don't Claim

Research on mitragynine in people is still limited. The National Center for Complementary and Integrative Health notes that kratom hasn't been shown to be safe and effective for any medical use.

So we don't say mitragynine treats, cures or prevents anything, and we don't make claims about how it'll make you feel. GÜD Tonics are flavored drinks, not medicine. If you're dealing with a health concern, talk to your doctor.

A Few Things to Know

GÜD Tonics aren't for anyone who is pregnant or breastfeeding. Never mix them with alcohol, and don't drink them before driving. Kava products have been linked to rare cases of liver injury, so talk to your doctor first if you have a liver condition or take medication. Kratom isn't allowed everywhere, so each product page lists the places we can't ship to.

How We Revise This Page

2 October 2026: Rewrote this page. The earlier version described mitragynine in mood and effect terms we can't stand behind, and gave timing and serving advice. This version sticks to what mitragynine is, where it shows up in our tonics and what we don't claim.
