Making your own capsules are very easy a little time consuming but well worth it for what you can save by doing your own.You do need a capsule maker, most health food stores sell them, and the capsules. They are cheaper if you can go online, I get mine at starwest. You can make up a pretty good size batch at once and you can use any combination of herbs that you need and not only is it cheaper this way you know exactly what is in your capsules, and with no added fillers.
A capsule maker will cost around 20 dollars and the refills depending on what size around 10 to 20 dollars for a 1000. There are 4 different sizes of capsule makers"3" "2" “1” “0” “00”
You can go to http://www.capsuleconnection.com/capsules for information on the different sizes and how much they hold, here is a little of the information that they have.
Capsule Sizing Information"00" holds about 735 mg. "0" size holds about 500 mg. #1 holds about 400 mg. #2 about 300 mg. #3 about 200 mg.
One teaspoon will fill about 7 "0" capsules and about 5 "00" capsules. The weight depends on the density of the powder you are using. Some powders are much denser than others. It also depends on the fineness of the powder. The only way to be sure is to check the weight of each individual material. On a scale accurate to within one-tenth of a gram or even to one-tenth of an ounce or even to a gram, you can weigh 24 empty capsules and then compare with the weight when full. If you only want a small amount of active ingredient, then you can mix with a material such as milk powder or rice powder as a filler. That way you can use "0" or "00" size capsules with various weights of active ingredients.
