Health food stores generally have the non-food items.  The flax seed and borage oil combination is in the refrigerated section.

I went to a place called Zerbo's in Livonia Michigan....I had written a list, and I found a guy stocking the shelves... He took my list and found everything on it for me. 

Other people have gone to Whole foods, but I have never been there.  I have  found many items at Krogers, but they aren't cheap.  Trader Joes has a lot of stuff at very reasonable prices, but mostly the food items.  Also, you can order some of these items from the internet.  The book and the supplement give you brand names that they like.

Are healthy bacteria like acidophilous.  They help with digestion in the gut.  I have used them for years whenever I feel bloated.  Usually found in the refrigerated supplement section of health food stores.
