Kratom capsules vs powder: price, contents and what gets tested
Same leaf, different product: price per gram, fill accuracy, what a certificate covers, and why capsules sit closer to Health Canada's line.
Powder and capsules contain the same thing: ground kratom leaf. The differences are price per gram, how accurately the contents can be known, what else is in the product, and how each format sits with Health Canada. This guide sets those differences out for buyers comparing Canadian vendors. It does not recommend either format or any use of them.

What is inside a capsule
A kratom capsule is leaf powder machine- or hand-filled into a two-piece shell made of gelatin (animal-derived) or hypromellose (HPMC, plant-derived). The two common sizes hold different amounts: a size 0 capsule typically holds around 0.4–0.5 g of kratom powder and a size 00 around 0.5–0.7 g, depending on how finely the powder is ground and how firmly it is packed. That variation is the first thing to know: a “0.5 g” capsule is a nominal figure, and fill weight is rarely verified on a certificate.
Side by side
| Powder | Capsules | |
|---|---|---|
| Typical Canadian price | About 14–21 cents per gram at kilo scale | Usually 1.5 to 3 times the powder price per gram |
| Contents | Leaf only | Leaf plus shell; occasionally flow agents such as magnesium stearate or rice flour |
| Fill accuracy | Whatever the bag weighs | Nominal per-capsule weight; varies by fill method |
| Lab testing | Tested as sold | Often tested as bulk powder before filling, not as finished capsules |
| Contamination points | Grinding, repacking | Grinding, repacking, plus the filling step and shell supplier |
| Regulatory posture | Sold as a botanical | A dosage form by design, closer to Health Canada’s line |
| Selection in Canada | Every vendor | A minority of vendors |
The testing gap
When a vendor that sells both formats posts a certificate, check what was sampled. A certificate for the bulk powder lot does not cover what happened at encapsulation: a hand-filling table, a capsule machine, the shells, any flow agent. A certificate for finished capsules, with a lot number matching the bottle, is the only one that describes the product. The same supplier-versus-retail-lot distinction from our lab testing guide applies one step further down the line.
Why capsules carry more regulatory exposure in Canada
Canadian vendors sell kratom as a botanical “not for human consumption” because Health Canada has authorized no kratom product as a natural health product. A capsule is hard to describe as anything other than a consumable dosage form. Health Canada’s 2017 recall of RGR Canada’s Matrix and Medicine Man products involved capsules, and the Edmonton seizures in 2018 included capsules alongside powders. That history is why some vendors do not sell them, and why our vendor pages flag capsule, tablet and edible lines; see the enforcement tracker and legal guide.
What to check before buying either
- A lot number on the bag or bottle and a certificate for that lot.
- For capsules: whether the certificate is for finished capsules or for bulk powder, and whether shell type and any added ingredients are listed.
- Price per gram, not per bag or per bottle. Divide by the stated net weight of kratom, not the capsule count.
- For anything labelled extract, enhanced or 7-OH in capsule form, read our extracts guide first; it is a different product category.
KratomSource’s Lab Scores are for leaf powder bought at retail. Where a vendor sells capsules of the same lot, the powder result is a reasonable guide to the leaf and says nothing about the filling step.

Frequently asked questions
How much kratom is in a capsule?
A size 0 capsule typically holds about 0.4–0.5 g of leaf powder and a size 00 about 0.5–0.7 g. These are nominal figures; fill weight varies and is rarely verified on a certificate.
Are kratom capsules more expensive than powder?
Yes. Canadian vendors usually price capsules at 1.5 to 3 times the per-gram price of the same powder.
Are kratom capsules legal in Canada?
Kratom is not a controlled substance, but no kratom product is authorized for consumption, and a capsule is a dosage form by design. Health Canada's 2017–2018 actions included capsule products.
Does a lab certificate for powder cover the capsules?
Only if the finished capsules were sampled. A bulk-powder certificate does not cover the filling step, the shells or any added flow agent.
