AFP-Peptizyde

is for breaking down gluten, casein, soy, meat, and other proteins. It can be used as an alternative to GFCF diet (gluten-free/casein-free diet sometimes used with autism), or used with GFCF if you are wanting to address other proteins still in the diet.
Plant based all fungal derived protease enzymes with DPPIV improved digestion of gluten, casein, soy and other proteins. Available in capsules and loose powder.

Zyme Prime

is for carbohydrates, fats, starches, sugars, gas and bloating, undigested food in the stool. Great for lactose intolerance. Helps some with proteins (but not a GFCF alternative). Tends to firm stools.
Plant based all fungal derived broad spectrum enzymes for general digestive support and carbohydrates and fats. Available as capsules and loose powders.

Peptizyde

Peptizyde is a combination of three different proteolytic enzymes isolated from plant sources. Each enzyme has a unique set of peptide bonds it prefers to break, so the combination of these enzymes allows much more efficient means of quickly and thoroughly breaking down (hydrolyzing) proteins to its smaller components.
The enzymes in Peptizyde work only on food proteins, not carbohydrates, fats, or other compounds, and do not interfere with medications or other supplements (unless they are also proteins, which is extremely unlikely). Peptizyde may be used in combination with other enzyme products.
