Vegan and Easily Digested

XPRS Nutra capsules are manufactured from 100% HPMC (hydroxypropyl methylcellulose), a plant-based material that dissolves efficiently in your digestive tract. This ensures maximum absorption of your supplement ingredients without the uses of animal products. They contain no additives or preservatives, making them a clean choice for vegetarians and vegans.

Unlike some gelatine capsules, HPMC capsules are resistant to cross-linking, meaning they remain stable over time. They also have a lower moisture content, which helps protect hygroscopic powders. Whether you’re filling herbal blends, vitamins, or nootropics, you can trust that these capsules will deliver your ingredients reliably.

Easy to Fill and Snap Shut Design

Filling these capsules is straightforward, whether by hand or using a capsule filling machine. The transparent material helps you see exactly how much powder you have added. Once filled, the patented Snap Shut Design ensures the capsule locks sely. This click-shut seal protects your ingredients from humidity and air, preserving potency. No more wasted powder from loose caps—every capsule stays closed until you are ready to uses it.

The design also minimises breakage during transport or storage. Each capsule is uniform in size and shape, so they work reliably with most size 4 filling machines. For manual filling, the slightly beveled edges make it easy to separate the cap and body.

Why Uses Empty Capsules for DIY Supplements?

Empty capsules give you the freedom to create your own custom supplement blends. Whether you are into nootropics, herbal powders, or fitness formulae, filling your own capsules allows you to control exactly what goes into each dose. XPRS Nutra Size 4 empty capsules make the process simple and precise—no more messy mixing or measuring. They are ideal for anyone managing a personalized supplement regimen, from biohackers to those following specific dietary protocols.

By using empty capsules, you avoid unwanted additives and fillers often found in pre-made supplements. You also save money by buying ingredients in bulk. Plus, capsule size 4 is perfect for smaller doses (120-240mg), giving you flexibility in your formulations.

How to Choose the Right Capsule Size

Size 4 capsules are amongst the smallest standard sizes, ideal for precise low-dose formulations. If you typically uses potent powders (like certain nootropics or adaptogens) that require only small amounts, size 4 is a great fit. For larger doses—say over 500mg—you might consider size 0 or 00. But for many common supplement powders, size 4 provides a convenient balance of capacity and ease of swallowing.

When selecting a capsule size, consider the density of your powder. A dense powder (like creatine) will weigh more per volume than a light herb. Always test your final fill weight to confirm dosage. The transparent shell helps here—you can see the fill level and adjust as needed.
