Collection: Capsule Filling Supplies

A capsule filling tray is a flat, multi-hole plate that holds the bottom halves of your empty capsules upright while you load powder across them. The holes are precision-machined to a specific capsule diameter, which is why size compatibility matters and why you cannot mix a size 00 capsule with a size 0 tray. Getting the fit right keeps capsules upright and powder contained, which is why matching tray size to capsule size matters from the start.

The Basic Mechanism

The tray holds the capsule body halves in place while you work. You pour your herbal powder over the surface and use a spreader card to sweep it evenly across all the openings. The capsule filling tray does the alignment work so that every capsule bottom is exposed to the powder at the same time. That is the core efficiency the tray delivers. Without it, you are filling each capsule one by one, which is slow and produces uneven results across a batch.

How Filling And Closing Works

Once the bottoms are filled, you tamp the powder down lightly to maximize the fill weight, then add a second pass if needed. Then you align the top tray, which holds all the capsule caps, and press down firmly until each one clicks closed. The two-tray design is what makes batch filling possible. One tray handles the bodies, the other handles the caps, and pressing them together seals the whole batch in a single motion. We designed the CAPSULE-IT around this principle because it is the most reliable way to get consistent results at home without specialized equipment.

Why This Beats Filling By Hand

Filling capsules one by one is impractical for more than a small handful. A single-capsule loader takes roughly 5 to 10 seconds per capsule, so 100 capsules could take 15 or more minutes, with inconsistent results. A tray handles all 100 simultaneously. Every capsule gets the same exposure to the powder spread, the same tamping pressure, and the same closing motion. That consistency matters if you are trying to hit a target dose reliably across a full batch.

Size selection is one of the first decisions to make, and it determines everything downstream. The tray you buy must match the capsule size you buy. A size 00 capsule filling tray only works with size 00 capsules. A size 0 tray only works with size 0 capsules. They are not interchangeable, so using the tray size that matches your capsule size is what keeps everything seated properly throughout the process.

Capsule Size Capacity At A Glance

The size you choose depends on how much powder you need per dose and how easy the capsule is to swallow. Size 00 is the most popular choice among our customers for adult use. It holds approximately 600 to 1,100 mg, depending on powder density, which covers most common herbal doses in a single capsule. Size 0 holds roughly 400-800 mg and is suitable for smaller doses or for people who prefer a slightly shorter capsule. Size 1 holds around 300-600 mg and works well for lower-dose formulas or for anyone who finds larger capsules difficult to swallow.

Powder Density Changes Everything

Two powders can fill the same capsule to very different weights. A dense powder like magnesium glycinate packs tightly and fills closer to the upper end of a size's capacity. A fluffy powder like lion's mane mushroom is light and airy. It fills the same capsule to a much lower weight without tamping. This means you need to weigh a few finished capsules when you start working with a new powder, rather than assuming a fixed gram count. We recommend keeping a digital kitchen scale on hand, available in our shop, for exactly this reason. It removes the guesswork and keeps dosing consistent across batches.

Matching Tray Size to Your Formula Goals

If your target dose fits comfortably in a size 00 capsule, that is the natural starting point. It is the most widely used size across our range, the most widely stocked, and the easiest to source in both gelatin and vegetarian options. If you are building a multi-herb blend in which each ingredient contributes a smaller amount, a size 0 tray may give you more dosing flexibility. Think through your intended formula before buying a tray, because switching sizes later means buying a new tray and new capsules.

Not all capsule filling equipment is built to the same standard. The most common complaint about cheap capsule-filling boards is inconsistent hole sizing. Holes that are slightly too large or too small cause capsules to sit at odd angles, which leads to uneven fills, another reason hole precision matters when choosing a tray. Material quality, surface finish, and how the tray cleans up all factor into whether you get reliable results batch after batch.

Hole Precision And Capsule Fit

We size our trays to hold the capsule body upright and snug. Secure enough to stay in place during filling, but with enough clearance to release cleanly when you press the tops down. A well-machined tray achieves this without you needing to force anything. If capsules are wobbling in the holes before you have added any powder, the tolerances are off, and you will have problems at every step that follows. That is not something you can compensate for with technique.

Material And Food Safety

The tray should be made from food-safe, BPA-free plastic that meets the material requirements covered by the NSF food equipment standard. Look for trays that specify food-grade materials rather than generic plastic. This is not a minor detail. Powders can sit in the tray for several minutes during filling, and some absorb compounds from their surroundings more readily than others. Our trays are made from food-safe materials for exactly this reason.

Cleanability Between Batches

That is why we built the CAPSULE-IT trays with a smooth, flat surface and clean-edged holes. Powder accumulates in deep recesses and rough surfaces and is difficult to remove completely with a simple rinse. A smooth tray washes easily with mild soap and warm water and dries without trapping residue. This matters particularly if you rotate among different herbs across batches, since residue from a previous batch can carry over into the next. The CAPSULE-IT has over 2,200 customer reviews, and easy cleanup comes up regularly as something people appreciate once they are into a routine.

Owning a good capsule filling tray gets you most of the way there. Using it correctly gets you the rest. The steps that most first-timers underestimate are powder spreading, tamping, and alignment before pressing. Each one affects your final fill weight and whether the capsules close cleanly. None of them is complicated once you know what you are looking for.

Spreading Powder Evenly

Pour your powder across the tray in a generous pile rather than a thin layer. Then use the spreader card to push it back and forth across the holes in multiple passes. The goal is to get every capsule body exposed to roughly the same amount of powder with each pass. Rushing this step can leave some capsules under- or overfilled relative to others, though it's worth noting that some variance, around 10%, is normal and expected; even store-bought supplements see batch-to-batch variation. We include a spreader card with our CAPSULE-IT for this reason. Take your time spreading before you move to tamping. It takes an extra minute and makes the whole batch more consistent.

Tamping Depends On Your Target Dose

How much you tamp, if at all, depends on how much powder you're trying to fit into each capsule to reach your target dose. This compresses the powder at the bottom of each capsule, creating room for a second layer. Skipping the tamp means your capsules will be lighter than expected, since tamping is what creates room for the powder to sit below the rim before closing. For fluffy powders like lion's mane, moringa, or ashwagandha, you may need two or three tamp-and-fill cycles to reach the desired fill weight. For denser powders like magnesium glycinate or turmeric, one tamp is usually enough.

Alignment Before You Press

Before pressing the cap tray down onto the filled bottom tray, confirm the trays are properly aligned. The two halves need to sit flush with each other. Keeping them aligned before pressing is what ensures every cap seats onto its matching body cleanly. Press slowly and evenly rather than with a single hard push. You should feel each capsule close in sequence, confirming the trays are properly aligned as you go.

A standalone tray is just the bottom plate, the part that holds the capsule bodies during filling. A capsule filling kit tray comes as part of a complete system that includes the bottom tray, the top alignment tray for the capsule caps, a spreader card, and sometimes a tamper tool. The distinction is practical. Without the top alignment tray, you are placing capsule caps by hand, one at a time, which eliminates most of the efficiency the tray was designed to provide.

What A Complete Kit Includes

Our CAPSULE-IT Original is a complete system. The kit includes the bottom body tray, the cap alignment tray, and the spreader card, giving you everything needed to go from empty capsules and loose powder to a sealed batch in one session. There is nothing extra to source separately before you can start. That matters for someone setting up for the first time, because a standalone tray without the matching cap tray is only half a system and will not produce the results you are expecting.

When To Consider Upgrading To A Larger System

Our Original 100-hole tray is the right starting point for most home users. It produces a meaningful batch in under 10 minutes and requires no more setup or cleanup than someone filling supplements for personal use wants to manage. Our CAPSULE-IT Pro Series 400 operates on the same principle at a larger scale, filling 400 capsules per batch. It makes sense if you are filling for a larger household or running consistent bulk batches where the time investment of repeated 100-capsule runs has become a real bottleneck.

Gelatin vs. Vegetarian Capsules In Any Kit

Whichever tray system you use, the capsule type you choose is a separate decision. We carry both gelatin and vegetarian options across our size range. Gelatin capsules are the most common and tend to be slightly less expensive. Vegetarian capsules are made from plant-derived cellulose and suit people avoiding animal products or follow specific dietary practices. Both types work the same way in the tray and close with the same mechanism. The tray does not distinguish between them, as long as the size matches.

This is the practical question behind most purchases in this category. You already know pre-made supplements exist. The question is whether making them yourself is actually worth the effort, or whether the convenience of a finished bottle justifies the price and the trade-offs that come with it. We think the comparison is worth making, honestly.

Cost Per Capsule

The math is straightforward. A bottle of 90 turmeric capsules from a supplement brand might run $25 or more. With a bag of our organic turmeric powder and a 1,000-count bag of empty capsules, you can make 300-plus capsules for a fraction of that cost. The pill-filling tray itself pays for itself within the first few batches. Over months of regular use, the savings compound. Most people who make the switch do not go back to buying pre-made.

Ingredient Control

Store-bought supplements often contain magnesium stearate, silicon dioxide, titanium dioxide, and other manufacturing aids that do nothing for the person taking the capsule, ingredients that fall under the FDA's Generally Recognized as Safe framework for additives rather than being reviewed as beneficial ingredients. They’re there to help the production line run faster, not to benefit you. When you fill your own capsules using our trays and powders, the only thing inside is what you choose to put in. For people who read ingredient labels carefully, that difference is the entire reason to make the switch.

Dose Flexibility

Pre-made supplements come in fixed doses decided by the manufacturer. You have no input on that number, a structure built into how FDA supplement labeling requirements define serving size on the label. When you fill your own capsules, you control the dose entirely. You can adjust it based on your body weight, your response over time, or a practitioner's recommendation. You can also blend two or more powders into a single capsule if your target dose for each ingredient fits within the capsule's capacity. That kind of flexibility does not exist in a finished bottle. The How to Use the Cap M Quik Capsule Filler page is a useful reference if you are comparing different tray-based systems and want to understand how the process works across machine styles before committing to one.
