All supplements have a heavy markup, and I only buy my supplements from my neighborhood health food/vitamin store. I was ordering Formula SF722 from the health food store and the owner had to look it up as she didn't normally carry the product. The brochure listed the owner's price as $13.95, but the owner charged me $28. Dr Jeff Mccomb charged $26 or so, and Amazon, the manufacturer and most online retailers charged the full $29.99.
As for the Glutagenics, I enjoyed the product because it had all of the products I needed to soothe and heal my intestinal walls (aloe vera, deglycyrrhizinated licorice, glutamine) within the one single product, and it was in a powder form, tasted great, and I mixed it into every glass of water I drank. All I know is that I started having less reactions to food and pollen until these days when I have zero discernible reactions at all.
