Bio-Strath is a unique, all-natural fortifying Whole Food Supplement. It is produced by a family-owned business founded in 1961 and is based on the work of Dr. Walter Strathmeyer who discovered that a special combination of herbs and yeast contained numerous strengthening substances needed by the human body for efficient performance and good health. This resulted in Bio-Strath: a highly nutritious supplement rich in minerals, vitamins, amino acids, enzymes and trace elements. The active principles from the herbs support and enhance the nutritional elements of the yeast, Saccharomyces cerevisiae. The herbs are angelica, balm, basil, chamomile, cinnamon, caraway, elder, fennel, horseradish, hyssop, lavender, licorice, peppermint, parsley, sage and thyme.
