The US Food and Drug Administration has granted GRAS status to Cypress Systems' flagship product, SelenoExcell High Selenium Yeast. This allows Cypress to sell the ingredient—which is the only certified 100 percent organically bound high-selenium yeast standardized with the National Cancer Institute—to the food and beverage manufacturing industry. The ingredient has been shown in a "Gold Standard" clinical trial published in the Journal of American Medical Association to reduce lung, colon, and prostate cancer incidence by 50-63 per cent. The combined level at which SelenoExcell is permitted to be used in selected food categories is up to 150 micrograms per day.

Cypress COO Mark Whitacre said in a statement, "The multi-billion dollar drug industry is one of the most profitable industries in the country, so there's less incentive for national healthcare to invest in alternative methods towards prevention for diseases like cancer. Our industry needs to join together and equalize this imbalance. Cypress Systems has dedicated many years and resources into Gold Standard research for selenium, which is almost unheard of for a supplement."
