Empty Vcaps are a vegetarian alternative to animal-sourced gelatin capsules. They are composed of inert vegetable cellulose and do not interfere with the digestion and absorption of the ingredients contained within. Empty capsules allow filling with oneās own powders at desired potencies, and avoid tablet binders and fillers. Buying powdered supplements and filling oneās own capsules can save up to 50% off most retail prices. For best results with empty capsuleĀ lling, try the Cap ām Quik capsule filler system.
