Empty capsules have become increasingly popular among health-conscious individuals, herbalists, and supplement manufacturers. They offer a convenient way to consume vitamins, minerals, herbs, and other supplements without the need for fillers, binders, or unwanted additives. But what exactly can you put in empty capsules, and how do you choose the right ones for your needs?
This guide will explore the different types of capsules, how to fill them, and what substances are best suited for encapsulation. Whether you're looking to create a custom supplement blend or simply avoid the taste of certain powders, this article will provide valuable insights into the world of empty capsules.
People use empty capsules for several reasons:
Custom Supplementation – Allows users to create their own vitamin and mineral blends tailored to their specific health needs.
Avoiding Fillers and Additives – Many commercial supplements contain unnecessary fillers; DIY capsules offer a purer alternative.
Masking Unpleasant Tastes – Some herbs, plant extracts, and superfood powders have strong or bitter flavors that are easier to consume in capsule form.
Better Absorption and Digestion – Certain supplements, such as probiotics, are better absorbed when encapsulated, as they bypass stomach acid.
Cost-Effective – Buying bulk powders and filling your own capsules can be cheaper than purchasing pre-made supplements.
Custom Dosages – Users can control the exact amount of ingredients they consume, which is especially helpful for individuals with specific dietary needs.
Choosing the right capsule depends on several factors, including the type of material, size, and intended use.
There are two main types of empty capsules:
| Type of Capsule | Description | Best For |
|---|---|---|
| Gelatin Capsules | Made from animal-derived gelatin. Affordable and widely available. | General vitamins, minerals, powders |
| Vegetarian Capsules | Made from HPMC (hydroxypropyl methylcellulose), derived from plants. | Vegan, vegetarian, and those with dietary restrictions |
| Pullulan Capsules | Made from fermented tapioca. Offers better oxygen protection. | Probiotics, sensitive herbal extracts |
Each type of capsule has its own benefits, and the choice depends on personal preferences and dietary restrictions.
Empty capsules come in different sizes, ranging from 000 (largest) to 5 (smallest). Below is a comparison of common capsule sizes and their capacities:
| Capsule Size | Volume (mL) | Powder Weight (mg) |
|---|---|---|
| 000 | 1.37 | 800-1600 mg |
| 00 | 0.91 | 600-1100 mg |
| 0 | 0.68 | 400-800 mg |
| 1 | 0.50 | 300-600 mg |
| 2 | 0.37 | 200-400 mg |
Choosing the right capsule size depends on the density of the powder and the desired dosage.
You can find empty capsules in health stores, pharmacies, and online marketplaces such as:
Amazon – Wide variety of brands and sizes.
Bulk Supplements – Great for purchasing large quantities at a lower cost.
Specialized Supplement Retailers – Websites like Capsuline and Capsule Depot offer high-quality capsules.
Empty capsules can be filled with a variety of supplements, including vitamins, minerals, herbs, and probiotics. Here are some of the most common options:
Filling capsules with vitamin and mineral powders allows for customized supplementation. Popular choices include:
Vitamin C – Supports immunity and skin health.
Magnesium – Essential for muscle and nerve function.
Zinc – Boosts immune function and wound healing.
Iron – Helps prevent anemia.
B-complex Vitamins – Supports energy production.
Many people prefer to take herbs in capsule form to avoid their strong taste. Some commonly encapsulated herbs include:
Turmeric – Anti-inflammatory properties.
Ashwagandha – Adaptogen that helps with stress and anxiety.
Milk Thistle – Supports liver health.
Ginger – Aids digestion and reduces nausea.
Ginseng – Improves energy and cognitive function.
Superfoods are nutrient-dense powders that can be encapsulated for easier consumption. Popular choices include:
Spirulina – Rich in protein and antioxidants.
Chlorella – Detoxifies heavy metals.
Maca Powder – Enhances energy and hormone balance.
Acai Berry – High in antioxidants.
Encapsulating probiotics helps protect them from stomach acid, ensuring they reach the intestines. Popular strains include:
Lactobacillus acidophilus – Supports gut health.
Bifidobacterium bifidum – Aids digestion.
Saccharomyces boulardii – Helps with diarrhea prevention.
Many individuals create custom supplement blends by combining different vitamins, minerals, and herbs to suit their health needs.
Some powders have a strong or bitter taste, making capsules an ideal option. Examples include:
Bitter Melon Extract
Berberine
N-acetylcysteine (NAC)
While most capsules are designed for powders, certain types can hold liquids. Vegetarian capsules and specially designed gelatin capsules (such as liquid-filled capsules) can be used for essential oils, fish oils, and herbal tinctures. However, liquids should not be too watery, as they can dissolve gelatin capsules prematurely.
Filling empty capsules can be done manually or with a capsule filling machine. Here's how:
Open the capsule by separating the two halves.
Use a spoon or spatula to fill the larger half with powder.
Press the smaller half back onto the filled half until it clicks.
Load empty capsules into the machine.
Spread the powder evenly over the tray.
Use a tamper to pack the powder into the capsules.
Close the capsules using the machine's mechanism.
A capsule filling machine speeds up the process and ensures consistent dosages.
Empty capsules offer a versatile and customizable way to take vitamins, minerals, herbs, and other supplements. Whether you're looking to create your own custom supplement blends, avoid fillers, or simply improve the taste of certain powders, encapsulation is a practical solution.
By selecting the right capsule size and type, purchasing high-quality powders, and using proper encapsulation techniques, you can take full control of your supplement regimen.
