U.S. Enzymes, Inc. is a company that specializes in the education and marketing of nutraceutical enzyme products to health professionals. U.S. Enzymes believes that supplementing daily with enzymes is the second most important factor that decides both the quality & quantity of life with the thoughts you think being number one.  Enzymes are the foundation of all life because they do more in the human body than all other nutrients combined.  In fact, all vitamins and minerals are considered co-enzymes.  In other words they do not work without enzymes.  Backed by almost twenty years of research and some of the top names in the industry our commitment is to introduce enzymes to the world.  Here’s a summary of our uncompromising approach to offering the finest enzyme products available.



We are dedicated to bringing enzymes to the world.  We have researched every enzyme product line in the marketplace and have found none to be of equal quality. The following five factors are the pillars that determine the quality of a finished enzyme product.

When you want to know how much work a particular enzyme will perform these numbers will tell you.  Enzyme activity numbers are equivalent to a cars horsepower- the larger the number the faster they can get from point A to point B.


This represents the number of different enzymes that are in a specific formulation. Here’s a breakdown of the 120 different digestive enzyme products that were recently compared. These are the numbers of different enzymes per capsule.

Our digestive enzyme products contain 23 separate and distinct enzymes. Some companies will perform different assays on the same enzyme and then list them as three different enzymes on their labels.


Glass bottles are the ultimate barrier from the harsh environment and there is no substitute. Non-absorbent rayon is used in combination with moisture-absorbing desiccants in every bottle. Flip-top lids are convenient, fast and easy to use. And under every lid is a tamper-proof heat seal barrier that guarantees purity as well as safety. All outer lid seals are tamper-evident.
