When Dr. Mehmet Oz sat in front of the camera last year for a promotional video for Walmart, it ostensibly was to inform his fans and viewers how best to improve their immune health.
“You may not realize that a quality probiotic is a proven immunity booster,” Oz said to the camera, before holding up a little green-and-blue package containing a supplement called TruBiotics, which purports to improve health by introducing good bacteria into the gut.
“Two probiotic strains can strengthen your digestive and immune health,” Oz said. “These two complementary strains can be found in TruBiotics.”
