Kratom is sold in more forms today than ever — from simple leaf powder to concentrated shots and tablets. The form makes a real difference in potency, consistency, risk and even legal status. Here is how the main types compare.
Quick comparison
| Form | What it is | Relative potency | Key considerations |
|---|---|---|---|
| Leaf powder | Dried, ground leaf | Lowest | Closest to traditional use; strong bitter taste; alkaloid content varies by batch. |
| Capsules | Leaf powder in capsules | Same as powder | Easier to take and measure; can cost more; quality depends on the powder inside. |
| Crushed leaf / tea cut | Coarsely cut leaf for brewing | Low | Traditional tea method; less common in US stores. |
| Extracts and shots | Concentrated liquids, resins or powders | High | Much stronger than leaf; easier to take too much; dependence risk may be higher. |
| 7-OH products | Concentrated or semi-synthetic 7-OH | Very high | Not equivalent to kratom leaf; banned or restricted in many states; under federal action. |
Kratom leaf powder
Powder is the most common form in the US and the closest to how kratom has been used traditionally. It is simply dried leaves ground fine. Because it is unconcentrated, its alkaloid content is the lowest of the commercial forms — but it still varies from batch to batch. Powder is known for a very bitter, earthy taste.
Kratom capsules
Capsules contain the same leaf powder in pre-measured form. People choose them mainly to avoid the taste and for convenience. They are not stronger than powder; they are the same material in a different package. Capsules typically cost more per gram, and you are relying on the vendor’s accuracy when filling them.
Kratom extracts and shots
Extracts are made by using solvents to pull alkaloids out of the leaf and concentrating them. They come as liquid shots, tinctures, resins and enhanced powders. Their strength can be many times that of leaf powder, and products are not standardized, so two extracts can differ widely. Health agencies note that concentrated products increase the risk of adverse effects, and dependence may develop faster. Extracts may also involve residual solvents, so lab testing matters even more.
7-OH tablets, gummies and strips
These products are built around 7-hydroxymitragynine, a compound present only in trace amounts in natural leaf. They are usually made by chemically converting mitragynine or heavily concentrating extracts. They are not a form of kratom leaf, even when marketed that way. Federal regulators are moving to schedule 7-OH above a set concentration, and many states already ban or cap it. Learn more in Kratom vs. 7-OH.
Kratom beverages
Ready-to-drink kratom beverages and teas have appeared in some markets. Some state KCPA laws prohibit kratom in conventional foods and beverages, and the FDA has said kratom is not a lawful food additive. Check your state’s rules.
Choosing more carefully
Whatever the form, the same principles apply:
- Look for third-party lab testing matched to the batch — see How to Read a Kratom Label.
- Be aware that concentrated forms carry greater risk than leaf.
- Do not combine kratom with alcohol, opioids, benzodiazepines or other sedatives.
- Talk with a doctor if you take medication or have health conditions.
- Check the law in your state — see our state-by-state guide.
Frequently asked questions
Are kratom capsules stronger than powder?
No. Capsules contain the same leaf powder; only the format is different.
What is a kratom extract?
A concentrated product made by extracting alkaloids from the leaf. Extracts are considerably stronger than leaf powder and are not standardized.
Are kratom shots the same as 7-OH?
Not always. Some shots are leaf extracts; others contain enhanced or semi-synthetic 7-OH. Check the label and lab report for 7-OH content.
