Conventional, Grocery, and Big Box Store Kibbles

Affordability plays a key role among this class of products. As indicated, the meat content is noticeably (unnaturally) low – the rest of the formulation is predominately starch ingredients. These generic diets are the least appropriate, and the least representative of the natural, archetypal canine/feline diet of any on the market.

"Natural," "Premium," "Super-Premium," "Grain Free," etc. Kibbles

In contrast with conventional grocery kibble, buyers of this group of products are health-conscious and willing to spend a bit more for nutritionally higher value products. The meat content of these diets is generally higher, with higher quality ingredients and beneficial minor ingredients (probiotics, prebiotics, enzymes) incorporated as well. Until recently, this class of kibble was the best available.

While these diets represent a small improvement over the generic, the fundamental flaw—the presence of significant starch (poly-sugar) in the diet—is unaddressed across the entire spectrum of premium brands and products—including the so-called "grain-free" foods. Starch continues to be used for the formation and cohesion of kibble.

Epigen™ (Original, Fish, Venison Formulas)

Epigen™ represents a giant step above the "premium" class through the inclusion of substantially more meat ingredients, and for the first time in the history of kibble, the exclusion of starch ingredients. After over five decades, kibble finally becomes more biologically appropriate thanks to the Starch Free™ concept.

Epigen 90™

The pinnacle of the dry, extruded kibble. The Starch Free™ concept is taken to its absolute limits with 90% meat ingredients.
