The Smart chart is easy to use, and it is exclusively on Wellshire Farms packaging. If the product does not contain any Soy it will read "SF", If it contains no Gluten it will read "GF", no Dairy "DF". The Protein "P8" amount represents the grams of protein (8) per serving. Our Smart Chart is just one more way that represents our commitment of delivering to you the healthiest meat products on the market. Feel Great, Eat Well!
