You may not think too hard about your capsules, but a lot of things can enter your body through capsules themselves. If you want to be very careful about what you use, these capsules are perfect for you. The gelatin in these capsules is 100% BSE free and the materials are derived from animal skin. You can use the capsules for anything like powders, vitamins, supplements and herbs. You may find yourself using them for anything you need. The only thing they should not hold is liquid because they can dissolve. The capsules even go so far as to hold Kosher and Halal certification! Simply keep them out of the direct sunlight and away from hot water and do not use them for liquid medication.
