Standard Process Catalyn Review
Dr. Royal Lee's first product, Catalyn, is more than a multivitamin, according to this page. It is presented as a source of complex, foundational nutrition and is described as containing 12 whole food ingredients, including whole food concentrates from the Standard Process Organic Farm. The page states that Catalyn was introduced in 1929. It is listed with the bullet points that it provides multiple vitamin catalysts for overall well-being and energy metabolism, and that it is designed to help bridge nutritional gaps in the diet. The product is listed under the heading Supports overall well-being. The page offers two tablet sizes: 90 Tablets at USD 19.20 (product number 2140) and 360 Tablets at USD 67.20 (product number 2160). The features listed for the 90 tablet bottle include a serving size of 3 tablets, a bottle count of 90, a case quantity of 36, a part content of 90 tablets, and 30 servings per container. The brand is given as Standard Process and the item is shown as In Stock with a listed price of 19.20 dollars each. The page also includes gallery images of the bottle and a Supplement Facts label, along with badges for Non-Dairy Formula and Non-Soy Formula. A large portion of the page is a list of Part Content items and option sizes that relate to other Standard Process products and kits, and a long list of nearby practitioners in Wisconsin and Illinois with options to become a patient or contact them. No written customer reviews, star ratings, or review totals appear in the scraped text. No ingredients list, full description of supplement facts, or barcode is printed in the text provided. The stated servings are 30 per container with a 3 tablet serving, so the 90 tablet bottle provides 30 days of use at that serving size.
