Understanding Kratom Alkaloids: Composition, Effects, and Research Insights

February 8, 2024

Kratom, scientifically known as Mitragyna speciosa, is a plant native to Southeast Asia, renowned for its complex pharmacology due to a variety of alkaloids present within its leaves. These alkaloids are organic compounds that exert significant physiological effects on the human body, contributing to kratom’s increasing popularity for pain relief, opioid withdrawal mitigation, and various other acute and chronic conditions.

What are Kratom Alkaloids?

Alkaloids are a class of nitrogen-containing compounds found in various plants, including kratom. They are known for their profound effects on human physiology, ranging from anti-inflammatory and mood-elevating effects to more potent actions such as sedation and analgesia. Kratom contains over 25 known alkaloids, with mitragynine and 7-hydroxy mitragynine being the most notable due to their significant impact on the body and mind. Mitragynine, in particular, constitutes about 66% of the total alkaloid concentration in kratom, influencing its pharmacological properties​​ [“”].

The Effects of Kratom Alkaloids on Humans

Kratom alkaloids interact with opioid receptors in the brain, producing effects such as sedation, pleasure, and decreased pain sensation. Mitragynine also interacts with other receptor systems in the brain, yielding a stimulant effect at lower doses and sedative, analgesic effects at higher doses. This dual action explains kratom’s ability to both soothe and energize users, making it a popular choice for various medicinal and recreational purposes​ [“”].

Alkaloid Concentration and Kratom Strains

The concentration of alkaloids in kratom leaves changes as the plant matures, influencing the effects of different kratom strains. Younger plants have higher mitragynine levels, while mature plants contain more 7-hydroxymitragynine. This shift in alkaloid content is visible through the changing color of the kratom leaf veins, from white in young leaves to green and eventually reddish as the plant matures. Therefore, the total alkaloid content and the specific strain of kratom significantly impact its effects on users​​ [“”].

Research and Clinical Implications

Despite the known effects of the primary alkaloids, mitragynine and 7-hydroxy mitragynine, many other alkaloids present in kratom remain pharmacologically unexplored. Recent advancements in kratom pharmacology have focused on these primary alkaloids, particularly their opioid pharmacology, but there is a desire to investigate the full spectrum of compounds within kratom. This includes their potential interactions with other receptors and their combined effect on the human body, highlighting the need for more comprehensive clinical and observational studies​​ [“”].

Kratom’s alkaloids offer a wide range of potential therapeutic benefits, from pain relief and mood enhancement to assistance with opioid withdrawal. However, the variability in alkaloid content across different strains and maturity levels of the plant emphasizes the importance of selecting the right type of kratom for specific effects. As research continues, a deeper understanding of kratom’s alkaloids and their pharmacological actions could unlock new possibilities for treating various conditions, underscoring the plant’s complex and multifaceted nature.

For further reading and a deeper dive into the research on kratom’s pharmacology and the specific effects of its alkaloids, resources such as the American Kratom Association and various scientific publications on platforms like PubMed and Frontiers in Pharmacology offer extensive information and insights​​​​​​​​ [“”] [“”] [“”] [“”].

The Mayo Clinic has expressed concerns about kratom, noting that while it was once considered a potential alternative to opioids, research has not found significant benefits and has highlighted several safety issues. These include adverse effects on brain function when combined with prescription medicines, potential for addiction with withdrawal symptoms similar to opioids, negative impacts on infant development, and risk of contamination with harmful bacteria like Salmonella. The Mayo Clinic advises consulting with a healthcare provider to explore safer treatment options​​ [“”].

Incorporating case studies into the discussion on kratom alkaloids provides real-world insights into the effects and management of kratom use. One area of focus has been the prenatal exposure to kratom and its outcomes on mothers and newborns. A systematic review highlighted concerns about neonatal abstinence syndrome, a condition where newborns experience withdrawal symptoms due to exposure to certain substances in the womb, indicating the need for careful consideration and monitoring of kratom use during pregnancy​​ [“”].

Another case study detailed the treatment of kratom use disorder with home induction of buprenorphine-naloxone. In this study, two patients who reported taking 35g of kratom per day were successfully managed through telehealth consultations, followed by unobserved home induction of buprenorphine-naloxone. This method proved effective for these patients, suggesting telehealth followed by unobserved home induction as a viable alternative to traditional induction methods, especially where treatment accessibility is limited. It also highlighted the importance of considering individual factors, such as the duration of kratom use and psychological aspects, in determining the most appropriate dose of buprenorphine-naloxone for treatment​​ [“”].

These case studies underscore the complexities of kratom’s effects on individuals and the potential challenges in managing kratom use disorder. They also highlight the importance of continued research and the development of tailored treatment approaches to effectively address the diverse impacts of kratom use.
