Written by the ALL-IN Capsule team. We make one of the machines in this guide, so we've tried to be clear about when another option is the better fit.
The short answer
For most people filling their own supplements at home, a manual 100-hole capsule filling machine is the best choice. It fills a full batch in minutes, needs no electricity, and costs about the same as a few bottles of pre-filled supplements. Smaller 24-hole fillers are cheaper but slow, and automatic machines are built for commercial production.

How to choose a capsule filling machine
1. Pick your capsule size first
A manual machine fills one capsule size only. Size 00 is the most popular for supplements, size 0 is easier to swallow, and size 000 suits bulky powders.
| Size | Approx. volume | Typical use |
|---|---|---|
| 000 | 1.37 ml | Large doses, bulky herbs |
| 00 | 0.90 ml | General supplements (most popular) |
| 0 | 0.68 ml | Daily supplements, easier to swallow |
| 1 | 0.48 ml | Smaller doses |
How many milligrams fit depends on how dense your powder is, so weigh a few filled capsules to check your dose.
2. Match the batch size to how often you fill
- 24 holes: fine for a few capsules a month, but slow for anything more.
- 100 holes: the sweet spot for home use. One batch covers a month of most daily supplements.
- 300+ holes: larger and pricier; worth it only for frequent, high-volume filling.
3. Look at loading and closing
The slowest part of filling capsules is placing the empty halves. Machines that let you shake capsules into the holes and close all capsules at once save the most time.
4. Check what's included
A spreader card, tamper and clear instructions make the first batch much easier.
5. Look for a guarantee
A money-back guarantee lets you try capsule filling without risk.

When another machine might suit you better

- You're starting a supplement business: look at semi-automatic or automatic machines.
FAQ
Can one machine fill different capsule sizes?
No. Manual machines are made for one size, so choose your size first.
How long does it take to fill 100 capsules?
About 10 minutes with a 100-hole machine once you know the steps.
Gelatin or vegetarian capsules?
Both work in all ALL-IN machines. Vegetarian (HPMC) capsules suit plant-based diets.
Is a capsule filling machine worth it?
If you take powdered supplements daily, filling your own lets you choose exact ingredients and doses and avoid fillers.
