The very same minerals that maintain human health also benefit pets. Veterinarians support the use of food-form selenium yeast like SelenoExcell to support pet health. Selenium yeast has been shown to improve glutathione peroxidase activity, which affects healthy immune function.
HUMAN GRADE INGREDIENTS
GOLD STANDARD RESEARCH
Selenium and Cancer in Animals
Early studies on selenium chose aging beagles as test subjects because the canine prostate functions similarly to humans. As such, researchers discovered a similar reduction in prostate cancer risk in canines as humans. Equine studies also show that selenium yeast is more effective than sodium selenite in increasing selenium blood levels and maintaining immune health. These and other studies have led veterinarians to recommend food-form selenium yeast for dogs, horses and other animals to reduce oxidative stress levels, improve glutathione peroxidase activity and lower prostate cancer risk.

To date, studies show that selenium levels in pet food can vary significantly, which can affect overall health and wellness. Researchers suggest that pet food companies consider the form of selenium when developing pet food formulations.
