No two products are identical if made by different manufacturers and some are more “equivalent” than others. Unlike Nutri-West, Food Research products, for example, do not contain any isolated USP vitamins nor industrial mineral salt ‘nutrients.’ Also, Standard Process Laboratories sometimes uses porcine glandulars, USP vitamins, claimed mineral salts, and/or colors, whereas none of these are in Food Research International products.
It should be noted that Standard Process uses its trademarked term “Protomorphogen” (which it abbreviates PMG) for some items and Food Research International uses the term Cytotrophin (the original term that Royal Lee received his patents with, but that Food Research International has permission to use), for some similar items.
As a general rule, products listed below as “Vegetarian” can take longer to notice efficacy in some cases than those with glandulars. Because Food Research nutrients are ALWAYS 100% FOOD and the other brands are not, Food Research products are always better in that way to products that seem to be ‘equivalent.’
A careful reading of the label shows that Catalyn® contains vitamin isolates as the primary source of each of the claimed nutrients.
