What are Kratom capsules and how are they made?

Mitra Science’s Kratom capsules are composed of top-quality Kratom powder, encased in capsule form. Our team of experts manages the production process with a partnered capsule manufacturer, ensuring that no shortcuts are taken in the production of 100 percent organic, additive-free kratom capsules.    

First, the finest quality Kratom leaves are sourced from select Mitragyna Speciosa trees in the forests of Southeast Asia. As the tree grows best in wet, humid, fertile soil, with medium to full sun exposure in areas protected from strong winds, the Mitra Science team identifies the most robust plants and carefully harvests the leaves by hand to ensure quality.

The leaves are then transferred to our laboratory, where they are expertly dried utilizing cutting-edge techniques and then ground into a fine powder immediately before encapsulation, to ensure maximum freshness.


Kratom Products 1

As with all of our products, when it comes to the capsule form, Mitra Science is proud to offer our prized clients a comprehensive array of Kratom capsule varietals, including:

  • 9% Mitragynine (M. Speciosa) Extract

One of our best-selling products, 9% M. speciosa extract is the top extract on the market today. This full-spectrum Mitragyna speciosa (Kratom) has been lab-tested at a 9% Mitragynine content.


  • Kra Thum Kok (Mitragyna Hirsuta) Powdered 100:1 Extract

Mitragyna hirsuta is a tall tree native to parts of Cambodia, Thailand and Vietnam. It is closely related to Mitragyna Speciosa, as both share the same family origin, Rubiaceae. While the plant contains alkaloids typical to the genus, the primary active constituent in Mitragyna hirsuta is mitraphylline (MTP). Results of scientific studies suggest that MTP may be a key modulator for regulating the plasticity of monocytes/macrophages and the attenuation of the inflammatory response.

  • Kra Thum Kok (Mitragyna Hirsuta) Powdered 25:1 Extract

The components are the same as above; however, this iteration of Mitragyna Hirsuta powdered extract is formulated at 25:1.


  • Mitragyna Javanica (Kra Thum Na)  Powdered 100:1 Extract

Mitragyna Javanica is also native to Southeast Asia, and closely resembles the Mitragyna speciosa (Kratom). However, the chemical makeup offers very distinctive differences. The main alkaloids in M. Speciosa, mitragynine and ajmalicine, are not found in Mitragyna Javanica. Instead, other compounds known as mitrajavine and  3-isoajmalicine are present.


  • Mitraphylline – Isolated Alkaloid from Mitragyna Hirsuta

An oxindole derivative, Mitraphylline is an alkaloid that is found in the leaves from the Mitragyna hirsuta tree, also known as Kra Thum Kok.


These varieties of Kratom capsules, and more, are available for purchase in bulk at Mitra Science’s always-low prices.
