13-OH
13-OH refers to 13-hydroxy corydalis yanhusuo compounds, typically blended with mitragynine (MIT) for a measured, consistent extract. Browse our full lineup of 13-OH products below.
This is NOT 7OH, MGM, or Pseudo.
What Is 13-OH?
13-OH is shorthand for 13-hydroxy compounds, most commonly sold as a measured blend with mitragynine (MIT). Brands formulate 13-OH tablets and extracts for consistent, predictable dosing, similar in concept to other single- or dual-alkaloid kratom extracts.
13-OH Is Not 7-OH
13-OH and 7-hydroxymitragynine (7-OH) are different compounds with different chemical structures, different alkaloid profiles, and different regulatory status. Check each product's label and Certificate of Analysis (COA) for exactly what it contains before you buy, and confirm your state's current kratom laws — they vary and change frequently.
Choosing a 13-OH Product
- Tablets — pre-measured, portable, easy to split for smaller servings
- MIT + 13-OH blends — combine mitragynine with a measured amount of 13-hydroxy compounds
- Extracts — higher concentration per serving; start low

Possible Side Effects
As with other kratom-alkaloid products, some customers report nausea, dizziness, drowsiness, or dry mouth. Effects vary by individual. Talk to a healthcare provider before use, especially if you take other medications or have an existing health condition.
