Category: 7-OH Education

7-hydroxymitragynine (7-OH) is a naturally occurring alkaloid in the kratom leaf. This article explains the science in plain English.

Chemical structure

7-OH belongs to the mitragynine class of alkaloids. It is structurally similar to mitragynine but with a hydroxyl group at a specific position that makes it more pharmacologically active.

Where it is found

In raw kratom leaf, 7-OH is present at about 0.01–0.05% of dry weight. Commercial extracts concentrate it many times over.

Research history

7-OH was first isolated in 1994. Modern research interest grew rapidly in the 2020s as commercial interest in refined extracts expanded.

Why it matters

7-OH is the focus of the most popular premium chewable products on the market today — browse the format.

Modern 7-OH tablets are the result of a multi-step process that takes raw kratom leaf and turns it into a precisely dosed, flavored chewable. This article walks through the process.

1. Leaf sourcing

Kratom leaf is sourced from mature plants in Southeast Asia.

2. Drying

Leaves are dried to preserve alkaloid content.

3. Extraction

The dried leaf is processed to extract and concentrate 7-OH.

4. Standardization

The extract is tested and adjusted so every batch contains a consistent amount of 7-OH.

5. Flavor blending

The extract is mixed with a flavor system — fruit-forward, citrus or unique profiles.

6. Tablet pressing

The blend is pressed into chewable tablets.

7. Lab verification

Every batch is third-party tested. Request a COA for any NUMBZ batch.

Onset time is one of the most common questions buyers have. This article covers the typical timeline and factors that affect it.

Typical onset

Most users feel effects within 30–60 minutes of taking a Numbz chewable.

Factors that affect onset

• Food in stomach: empty stomach = faster onset.
• Dose: higher doses may onset slightly faster.
• Body composition: metabolism and weight play a role.
• Tolerance: experienced users may feel effects more subtly.

Duration

Effects typically last 4–6 hours, with a gradual taper.

Tips

For faster onset, take on an empty stomach. For a smoother experience, take with a light snack.
