Peptizyde™ (pronounced "Pep-ta-zyde") 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.

The aminopeptidase enzyme dipeptidyl peptidase IV, or DPP IV, is able to hydrolyze and inactivate the exorphin peptide, casomorphin. However, for maximal protein breakdown, it should be combined with other proteases with different and less stringent peptide bond specificity. For this reason, Peptizyde™ also contains papain (from papaya) and another fungal protease with high activity in acid conditions. These enzymes are present in Peptizyde™ in high amounts for the purpose of quickly hydrolyzing proteins while the food is still in the stomach. The ability of Peptizyde™ enzymes to withstand the low pH of the stomach and remain active under acidic conditions allows hydrolysis of casein and gluten prior to entrance into the small intestine. Casein and gluten, in the presence of pancreatic enzymes in the duodenum, can break down into exorphin peptides that may be readily absorbed from the intestine (these peptides are not absorbed from the stomach). Peptizyde™ supplements the "normal" hydrolysis of casein, gluten, and other food proteins such that the exorphin peptides are not produced because the specific cleavage pattern to produce these peptides is altered.

Peptizyde™ is different from other enzyme products in that it contains only those enzymes needed for protein hydrolysis. No other enzymes have been added. This allows one to customize enzyme supplementation to their specific dietary needs. Another advantage to this approach is that less potential exists for intolerance reactions due to additional and perhaps unnecessary enzyme proteins. Also, by using only three enzyme blends in Peptizyde™, larger amounts of each enzyme can be added per capsule, insuring that more hydrolysis of food protein can take place in the short time that food is in the stomach.

Peptizyde™ is also different in that it has allowed many families dealing with food intolerances and the gluten-free/casein-free diet to safely modify or even abandon the diet, thus allowing families more choice in foods available, better nutrition (by re-incorporating important protein sources back into the family diet), and much less stress and worry from fear of food reactions.

One other important difference between Peptizyde™ and other products is the scientist who developed the product. Devin Houston, Ph.D. is the owner and creator of all Houston Nutraceutical products. Dr. Houston’s experience in and knowledge of enzymes, nutrition, and human biochemistry helped develop a product that is now enabling many families to live better and healthier.

Reported Benefits
Appetite may increase as well as showing more interest in other types of foods. Better disposition and mood were also noted. Peptizyde™ may allow for re-introduction of dairy and wheat products to the diet without abnormal behaviors occurring. Benefits from Peptizyde™ do vary with each individual and may be affected by other supplements and dietary composition. Other supplements, especially vitamin and minerals, may be decreased in amount or frequency of dosing as more nutrition is derived from diet with enzymes.

Peptizyde™ is also recommended for high protein diets and athletic training; and dosing may be increased for those meals that are higher in meat protein.

Reported Side Effects
In those with sensitivity to certain peptides, initial use of Peptizyde™ may result in the so-called "peptide withdrawal syndrome", as the food-derived peptides are decreased. This may present as hyperactivity, irritability, increased aggression, tantrums, etc. for a period of several days to as long as a month. In most cases, this syndrome is resolved when dosing of 1 capsule per meal is obtained for a period of several days. Most report the cessation of negative behaviors after about 3 weeks. Often, the syndrome can be minimized by starting with low doses (¼ - ½ capsule) and working up to 1 capsule per meal within about 2 weeks. If behavior during this initial dosing becomes a concern, stop the enzyme supplementation for a period of 2 weeks (or until child returns to former behavior), then re-introduce Peptizyde™ at a much reduced dose and increase dosing at a much slower rate than previously used. Many parents also reported that decreasing or discontinuing certain vitamin supplements containing high amounts of B6 or P5P would alleviate much of the hyperactivity. Addition of HN-Zyme Prime to Peptizyde™ supplementation also seemed to reduce side effects from peptide withdrawal syndrome.

Using Peptizyde™ as an Alternative or Supplement to the GFCF Diet
The procedure recommended by most who have successfully abandoned the GFCF diet using Peptizyde is to use the enzymes while maintaining the diet for a period of at least 2 months. When challenging with foods known to be a problem, use small portions initially with 1 or 2 capsules of Peptizyde™. The intention is to provide more than enough Peptizyde™ to counter the effects of casein/gluten. If the challenge was successful, increasing the amount of food given may be attempted, keeping in mind that more Peptizyde™ may be necessary to counter the increased size of the food challenge. For occasional use, up to 4 capsules may be given for infractions, any more than that will probably not provide any additional benefit.

Contraindications for Enzyme Supplementation
These enzymes should NOT be used under the following circumstances: active stomach or duodenal ulcers, severe bowel inflammation (characterized by blood in stools), hemophilia and other bleeding disorders, or within a week of scheduled surgery. This product may not be appropriate for those with known allergies to Aspergillus enzyme proteins or papaya, though non-specific mold allergies do not necessarily preclude use of fungal enzymes. Consult your medical doctor for further advice, and err on the side of caution. Those with known anaphylactic allergic reactions to fungal proteins should NOT ingest fungal-derived enzymes. This product will NOT allow celiac patients to go off a gluten-free diet.

Maximum dosing
No upper limit has been established for enzyme dosing, and animal studies found no toxicity at dosing as high as 2000 milligrams per kilogram of body weight per day for 90 days. Most find using 1 to 2 capsules per meal is adequate, and most likely no further benefits will occur with higher dosing, though as much as 4 capsules may be given for the infrequent and large food challenges. Maximum consistent dosing per day is recommended to be no more than 9 capsules per day.
