Just visit a good health food store and you'll see all the wonderful super-green food products! If it's a good store they should have a whole section for these concentrated foods. The best ones that I know of are Garden of Life's Perfect Food,
Dr. Schulze ' Super Food, and E3live, all of which are available online.
Vitamin A supplements are no good. You have to get it naturally in an oil for the body to be able to use it right away. All the cases of vit A toxicity have occurred due to supplement pills. They just aren't all that safe. So Cod Liver oil is the best way to go. In the FAQ you'll see a post for supplments and where to buy them. There's a link to a good catalogue that has pure cod liver oil. The one I have is a bottle of oil, but they may have another that are gelatin pills so that they travel easier. If you get the gelatin capsuled oils you have to take large handfulls every day, several times a day, to get enough oil.
