7-Hydroxymitragynine (7-OH) Uses, Effects, Risks, and Safety Information

7-Hydroxymitragynine, commonly known as 7-OH, is a naturally occurring alkaloid that is derived from the kratom plant (Mitragyna speciosa). But concentrated 7-OH products are very different from regular kratom leaf as they can contain much higher amounts of this opioid-active compound. While research into 7-OH is in progress, the available data are worrying regarding its potency, dependence liability and safety.

What Is Mitragynine?

7-Hydroxymitragynine is an alkaloid found in kratom. Natural kratom leaves contain only trace amounts of 7-OH. However, some commercial products have increased or focused levels.

The concentrated 7-OH products are considered potent opioid products by the U.S. Food and Drug Administration (FDA), which has warned consumers about their potential for serious harm. The FDA also states that no 7-OH product has been proven to be a safe and effective medicine.

7-OH and Kratom

7-OH naturally occurs in kratom but is only a minor component of the plant. Thus, it is not correct to conclude that concentrated commercial products are equivalent to traditional kratom leaf.

Recent studies have also found that some products marketed as kratom extracts contain significantly elevated levels of 7-OH. This is important because higher concentrations can mean much higher exposure than normal levels.

How Does 7-Hydroxymitragynine Function In The Body?

7-OH has a high affinity for mu-opioid receptors which are implicated in pain, reward, sedation and other nervous system functions. Research has shown that 7-OH exhibits opioid-like activity and can generate effects similar to conventional opioids.

Effects of Research

Scientists have explored the effects of 7-OH, such as:

• Binding to mu-opioid receptor
• Laboratory models of pain-related effects.
• Sedatives
• Reinforcement and reward
• Dependence, physical
• Withdrawl symptoms
• Respiration depression

Importantly, much of the evidence is based on laboratory and animal studies, rather than controlled human clinical trials. So, researchers can’t simply translate these findings into proven medical benefits for people.

7-Hydroxymitragynine Risks

Concentrated products may be associated with serious safety concerns due to their potent opioid activity. The FDA has said there are adverse effects associated with 7-OH products including addiction, anxiety, depression, gastrointestinal problems, insomnia, seizures and opioid-like withdrawal symptoms.

Addiction and Withdrawal

Repeated use of opioid-active substances may result in tolerance and physical dependence. So repeated use can cause withdrawal symptoms when you stop using it.

Reported withdrawal symptoms with 7-OH products can include restlessness, body aches, fatigue, irritability and cold sweats.

Suppression of Respiration

Breathing is one of the biggest worries. Preclinical studies demonstrate evidence of respiratory depression, physical dependence, and withdrawal effects associated with 7-OH, according to the FDA’s scientific evaluation.

Therefore, consumers should not assume a product is safe because it is marketed as botanical, herbal, or derived from kratom.

Is 7-Hydroxymitragynine FDA-Approved?

None. The FDA says that there are no FDA-approved drugs that contain 7-OH to treat pain, anxiety, opioid withdrawal, or any other medical condition.

The FDA also has taken enforcement action against companies marketing concentrated 7-OH products as foods, dietary supplements or unapproved drugs.

Why Product Labelling Matters

There are a number of different commercial 7-OH products, in tablets, gummies, drink mixes, and shots. But lab studies have found that the labels on some products don’t correspond with the actual amount of 7-OH contained in them.

Consumers should not therefore accept marketing claims at face value when considering these products.

Natural Kratom and 7-Hydroxymitragynine

The natural leaves of kratom are rich in alkaloids, with mitragynine being the most common alkaloid. 7-OH is also produced naturally at much lower levels.

However, concentrated 7-OH products may provide significantly higher exposure. The FDA differentiates these concentrated products from regular kratom leaf.

This is important because a product labelled “kratom” might not have the same chemical profile as the traditional botanical leaf.

State of Research

Researchers are still studying 7-OH and other related kratom alkaloids. The activity of the receptor, its pharmacology, metabolism, toxicity and dependence have been studied.

That said, there’s no evidence that 7-OH is an approved or proven treatment. A systematic review also reported that there are insufficient controlled human clinical trials to establish the safety and efficacy of kratom alkaloids as opioid substitutes.

Safety precautions

Concentrated 7-OH products may have opioid-like effects, so people should regard them as potentially hazardous substances, not ordinary dietary supplements.

Do not combine opioid-active substances with other sedating substances unless instructed to do so by a healthcare professional trained in using these products. If you or someone you know has severe sleepiness, trouble breathing, loss of consciousness, seizures, or other serious reactions after taking a 7-OH product, call emergency services.

Summary

7-Hydroxymitragynine (7-OH) is a potent kratom-related alkaloid that acts at opioid receptors. Kratom contains it in trace amounts, but commercial products may have much higher concentrations. Existing data raise concern about dependence, withdrawal, respiratory depression and other important adverse effects.

Most importantly, 7-OH is not an FDA-approved drug, and consumers should not use claims that the substance safely treats pain, anxiety, opioid withdrawal or other medical conditions. Researchers are still probing the compound, but major questions about safety and therapeutic use remain.
