Kratom is quickly becoming one of the most searched herbal supplements in the U.S., but there’s still a lot of confusion surrounding it—especially when it comes to 7-hydroxymitragynine, one of its most potent alkaloids. If you're researching Kratom for the first time, looking to buy from a reputable source, or just trying to make sense of the science, this article answers the most frequently asked questions about Kratom and 7-hydroxymitragynine.
What is Kratom?
Kratom (Mitragyna speciosa) is a tropical tree native to Southeast Asia. Its leaves contain compounds that can have stimulating effects in small doses and sedative or pain-relieving effects in higher doses. It has been used for centuries in Thailand, Indonesia, and Malaysia for traditional medicine, but has recently gained attention in the U.S. as an alternative wellness supplement.
What Is 7-Hydroxymitragynine?
7-hydroxymitragynine (often abbreviated as 7-OH or 7-HMG) is one of the major active alkaloids in Kratom. Though it occurs in trace amounts naturally, it is considered the most potent psychoactive component in Kratom. It binds to the brain's mu-opioid receptors, making it a key reason Kratom may provide pain relief, relaxation, and euphoria.
Fun Fact: 7-Hydroxymitragynine is up to 13 times more potent than morphine in lab studies, though its actual effects in Kratom leaf form are much milder due to its low concentration.
How Much 7-Hydroxymitragynine Is in Kratom?
This is one of the most common questions. On average, 7-hydroxymitragynine makes up only about 0.01% to 0.02% of raw Kratom leaf by dry weight. Most of Kratom’s effects are attributed to mitragynine, which the body partially converts into 7-hydroxymitragynine during metabolism.
Is 7-Hydroxymitragynine Safe?
Safety largely depends on dosage, frequency, and product quality. In natural Kratom leaf form, the 7-hydroxymitragynine content is minimal and generally considered safe when used responsibly. However, enhanced or synthetic products that contain artificially elevated levels of 7-OH may carry higher risks of dependency, tolerance, or side effects.
Is Kratom Legal in the United States?
Kratom legality varies by state. While Kratom is legal at the federal level, several states and municipalities have banned its sale or possession. Always check local laws before buying Kratom.
Tip: Look for vendors who are American Kratom Association (AKA) certified and offer third-party lab tests to ensure safety and legality.
What Are the Benefits of Kratom?
People use Kratom for a variety of reasons, including:
Pain relief
Mood enhancement
Increased energy (at low doses)
Relaxation and sleep support (at higher doses)
Opioid withdrawal management
These effects are largely linked to mitragynine and 7-hydroxymitragynine binding with opioid and adrenergic receptors in the brain.
What’s the Difference Between Mitragynine and 7-Hydroxymitragynine?
Mitragynine is the primary alkaloid in Kratom, making up to 66% of the total alkaloid content. It's less potent but much more abundant. 7-Hydroxymitragynine, though far more potent, is only present in very small amountsnaturally.
Think of mitragynine as the base and 7-OH as the activator—it’s the conversion that produces much of Kratom’s euphoric and analgesic effects.
Can Kratom Show Up on a Drug Test?
Standard drug tests (like a 5-panel) typically do not screen for Kratom. However, specialized tests can detect mitragynine or 7-hydroxymitragynine if Kratom use is suspected. Detection depends on dosage and metabolism but is generally 1–7 days in urine.
Where Can I Buy Safe, Lab-Tested Kratom?
When buying Kratom, especially online, look for vendors who:
Provide third-party lab results
Are registered with the American Kratom Association
Clearly list alkaloid content (mitragynine and 7-OH levels)
Follow GMP (Good Manufacturing Practices)
