Collection: Capsule Filling Machines

A capsule filling machine is a tabletop tool that lets you fill dozens of capsules at once, rather than one at a time. Understanding how the mechanism works helps you get consistent results from your very first batch. Here is what you need to know before you start:

The Tray-Based Fill System

The CAPSULE-IT uses a tray system to load, fill, and seal capsules in a single workflow. You place empty capsule bodies into the base tray, spread your powder across the surface, use the included spreader card to level and tamp, then join the cap tray to press everything closed at once. One cycle produces 100 filled capsules in roughly 10 minutes. This approach removes the inconsistency of hand-packing, where eyeballing each capsule leads to uneven doses across a batch. For anyone who takes their supplements seriously, that consistency matters.

Semi-Automatic vs. Manual Operation

The CAPSULE-IT is a semi-automatic capsule-filling machine, meaning the machine guides the process while your hands do the work. There are no motors or electronics involved. That is a feature, not a limitation. Fewer moving parts mean fewer things to break, easier cleanup, and no power source required. For most home users filling a few hundred capsules at a time, semi-automatic is the right level of complexity. A manual capsule filling machine in the truest sense would be filling each capsule individually by hand, which this design replaces entirely. The semi-automatic format keeps things simple without sacrificing speed or accuracy.

Scaling Up With The Pro Series 400

The CAPSULE-IT Pro Series 400 uses the same tray-based method but produces 400 capsules per batch rather than 100. It suits households with higher-volume needs, or anyone who runs multiple back-to-back cycles in every session. The mechanics are identical to the Original CAPSULE-IT. The scale is simply different. If you are filling capsules for a family, sharing batches with others, or working with several different powders at once, the Pro Series saves significant time over the course of a month. If you are just starting out, the Original is the better entry point before committing to a higher-volume setup.

Capsule size is one of the most consequential decisions you will make before purchasing, and it is also one of the most misunderstood aspects of setting up a home capsule-filling kit. Getting the size wrong means buying a second machine or overhauling your entire supply of empty capsules. Here is how to think through the decision correctly:

How The Sizing System Works

Capsule sizes run counterintuitively. The larger the number, the smaller the capsule. Size 000 is the biggest option and holds the most powder per capsule. Size 00 is the most widely used size for home supplement makers. Size 0 is a step smaller, and size 1 is the smallest available in our lineup. Our capsule filling equipment is sold by size, so the machine you order must match the empty capsules you plan to use. They are not interchangeable across sizes. Double-check your capsule order before it arrives so your first batch is not delayed by a mismatch.

Matching Size To Your Powder And Serving Needs

The right size depends on two factors: the density of your powder and your target serving amount. A dense powder like magnesium glycinate packs more milligrams per gram than a bulkier powder like moringa leaf. If your intended serving falls in the 500 to 800 milligram range, size 00 is usually sufficient. If you are working with a very light or fibrous powder and need a larger fill, size 000 gives you more room per capsule. When in doubt, size 00 is the safest starting point for most herbal powders. You can always adjust your serving by taking more capsules rather than switching to a larger size.

Sizing For Children Or Smaller Servings

Size 1 capsules are worth considering if you are making capsules for children, for ingredients that require a very small serving, or for powders that are extremely potent in small amounts. A smaller capsule is also easier to swallow for people who have difficulty with larger supplements. Keep in mind that a smaller capsule holds less powder per unit, so you may need to take more capsules to reach your intended serving. Plan your bulk powder supply accordingly before settling on a size.

Knowing how to operate your machine is one thing. Getting repeatable, well-filled capsules, batch after batch, takes a bit more attention to detail in your setup. For a full step-by-step walkthrough, see our guide on How to Use the Capsule It at Home Capsule Filling Machine. These are the steps and habits that make the biggest difference:

Preparing Your Powder Before You Fill

Powder prep is where most first-time users run into problems. If your powder is clumped or unevenly ground, it will not spread or tamp properly across the tray. Sift any powder that has been stored before you use it. Finely milled powders fill more predictably and leave fewer air pockets in the finished capsule. If you are working with multiple ingredients, blend them thoroughly before loading the tray so every capsule in the batch contains the same ratio of each powder. Taking five extra minutes here saves a frustrating batch later.

Tamping And Spreading Technique

Once you have loaded your powder onto the tray, use the included spreader card to distribute it evenly across all the capsule bodies. Apply light, consistent downward pressure as you spread. Tamping compacts the powder into each capsule body so more fits per capsule, and the fill is uniform. Most users find that two to three passes with the spreader card, followed by one firm tamp, gives the best results. Do not rush this step. The consistency of your final capsules depends heavily on how evenly the powder is distributed before you seal the tray.

Sealing Without Spills

Joining the cap tray to the body tray is straightforward, but alignment matters. Line the trays up carefully before pressing down. Apply even pressure across the entire surface so every capsule seals in one motion, rather than using a rolling press that can cause misfires at the edges. Once sealed, the capsules sit securely in the green tray — simply push them out by hand or tip them onto a plate, then transfer to a mason jar or zip-lock bag for storage.

A digital kitchen scale is useful here for spot-checking a few capsules from each batch to confirm your fill weight is consistent. If you are using a different filler, see our guide on How to Use the Cap M Quik Capsule Filler for model-specific technique notes. If you are using a different filler, see our guide on How to Use the Cap M Quik Capsule Filler for model-specific technique notes. If the weight varies significantly between capsules, your tamping technique is the first place to revisit.

Note: There will generally be a slight variance (~10% or so) between capsules — this is completely normal and also consistent with what you'll find in store-bought supplements.

Store-bought supplements are convenient, but convenience comes with tradeoffs that many DIYers are no longer willing to accept. For a deeper look at the full case for going DIY, see Why You Should Fill Your Own Capsules. Making your own capsules puts you in control of what goes into each one, how much, and in what form. There are a few clear reasons why more people are choosing this route:

You Know Exactly What Is In Each Capsule

Pre-made supplements often contain fillers, flow agents, and binders alongside the active ingredient. These additives serve the manufacturer's production needs, not yours. Under FDA dietary supplement oversight, manufacturers are responsible for evaluating their products before marketing, but the presence of excipients and additives is common and permitted. When you fill your own capsules using single-ingredient herbal powders, the capsule contains exactly what you put in it and nothing else. For people with sensitivities to common additives like magnesium stearate or silicon dioxide, this level of control is not optional. It is the whole point. Making your own capsules also means you can adjust the serving size to suit your needs rather than accepting whatever dose a manufacturer has standardized. For more on how supplements are categorized and regulated, see NIH supplement guidance.

Cost Per Serving Is Significantly Lower

Buying a bulk herbal powder and filling your own capsules costs a fraction of what a comparable pre-made supplement costs per serving. The markup on finished supplements reflects packaging, marketing, and retail distribution. None of that applies when you are buying powder and filling capsules at home. The upfront cost of a capsule filling machine pays for itself quickly when you compare it against months of buying the same ingredient in finished supplement form. Many of our customers find that their first few bulk powder orders more than cover the combined cost of the machine and empty capsules.

You Control The Capsule Type

When you buy pre-made supplements, you rarely get to choose whether the capsule shell is made of gelatin or is vegetarian. That choice is made for you. Filling your own capsules means you select the shell material that fits your dietary practice. We carry both gelatin and vegetarian empty capsules in all compatible sizes. Gelatin capsules are animal-derived and are a traditional choice. Vegetarian capsules are typically made from hydroxypropyl methylcellulose and suit plant-based or vegetarian lifestyles. Neither type is better in terms of how well they fill or seal. It simply comes down to what is right for you.

Not all home capsule-filling setups are equal, and the differences matter more than they might at first glance.

A few specific factors separate a kit that works smoothly from one that frustrates you after the first batch. Here is what to evaluate before you buy:

Build Quality And Material

A well-built machine should feel solid without being overly heavy. Look for food-safe materials throughout, including the tray, spreader, and tamper. The same consistency standards that apply to commercial producers under supplement manufacturing standards are worth keeping in mind when evaluating any equipment you use at home.

Cheap plastic trays flex under pressure, which leads to misaligned capsules and poor seals. The CAPSULE-IT is constructed to withstand repeated use without warping or cracking. This matters because you will be pressing down on the tray with consistent force every session. A machine that holds its shape reliably produces consistent capsules. Build quality is especially important if you plan to fill capsules weekly over months or years rather than occasionally.

Compatibility With Capsule Type

Some capsule fillers are designed to work only with pre-joined capsules, while others require separated caps and bodies. Our CAPSULE-IT is compatible with both gelatin and vegetarian capsules, as long as they match the machine's size. We carry both types in multiple sizes, so you can choose the capsule material that fits your dietary preferences without changing your equipment. Always confirm compatibility before ordering a bulk supply of empty capsules. Buying 1000 capsules in the wrong size is an avoidable mistake that a quick size check prevents.

What Comes In The Box

A complete capsule-filling kit should include everything you need to fill your first batch without any additional purchases. The CAPSULE-IT includes the base tray, cap tray, spreader card, and tamper. You will also need empty capsules and your powder of choice, both of which we sell separately or in bundles. If you are new to capsule making, our DIY supplement guides walk through the full process and help you calculate serving sizes and fill weights before your first session. Starting with a bundle rather than piecing together components separately is often the most straightforward path for first-time buyers.

Pairing Your Machine With The Right Powders

The machine itself is only part of the equation. The quality of your finished capsules also depends on the powder you fill them with. We carry a range of organic herbal powders including turmeric, lion's mane, cordyceps, beet root, moringa, and magnesium glycinate. Each powder is sourced and milled to a consistency that works well in a tray-based filler. Using a coarse or unevenly ground powder in any capsule filling kit will make the process harder and the results less consistent. Starting with a quality powder makes the whole workflow smoother from the first batch.
