Hi Bluelq,

Most gel caps are gelatin with animal products in them.

You can get vegetable cellulose caps usually made from potato starch which are much better as long as you don't have potato allergies. They're just a bit more expensive than gelatin but prices are coming down. The most popular name brand of vegi caps are v-caps. Many companies bag them under their own name.

Caps usually come in sizes of single (0) or double (00) and sometimes even triple (000). the single usually hold about 500mg and the 00's usually hold about 750mg so I would be surprised if you can put 2 grams in one cap. The triple's more expensive you could probably get about 1 gram to 1.25 g per cap.
