Vira-Bac-YST™ enchances immune health, contains fiber, and is a Chlorophyll source.

Vira-Bac-YST™ naturally contains carbohydrates, lipids, proteins (including essential amino acids), as found in Buckwheat Leaf and Juice, Olive Leaf Concentrate, and Wild Oregano–all the nutrients shown above are contained in these foods. Unlike many so-called “natural” formulas, Vira-Bac-YST™ is comprised of only food, no synthetic USP nutrients or isolated mineral salts, but only contains foods and food concentrates.

Numerous university studies have concluded that supplements containing food nutrients are better than USP isolates. Food nutrients are better because they contain important enzymes, peptides, and phytonutrients CRITICAL to the UTILIZATION of vitamins and minerals which are not present in isolated USP nutrients. Published research has concluded that food vitamins are superior to synthetic/USP vitamins.

Some of these studies (or citations) may not conform to peer review standards, therefore, the results are not conclusive. Professionals can, and often do, come to different conclusions when reviewing scientific data. None of these statements have been reviewed by the FDA. All products distributed by Doctors’ Research, Inc. are nutritional and are not intended for the treatment or prevention of any medical condition.
