Empty gelatin capsules are for people who like having a little more control over their supplement routine. Instead of buying everything pre-capsuled, you can buy certain ingredients in bulk, measure exactly how much you want, and build your own capsules at home. Size 0 capsules generally hold around 400–600 mg of most powdered ingredients, depending on the powder.
If you've ever been the type to think "I bet I could optimize this even more if I just made it myself," these are probably for you. Most people will never bother with home encapsulation, and that's totally fine. But if you're someone who enjoys experimenting with bulk powders, custom formulas, or dialing in your own supplement routine, getting into that level of detail might just add a little aura to the way you approach your health.
