Yes, we often update products long after we’ve designed them. Virex Complex is no exception. This revision of an already GREAT formulation (if your repeat purchases are any indication) is the second time in the relatively short life of this product (first introduced in early 2000). First we added mangosteen extract after extensive research into its effectiveness in supporting the body in fighting off viruses and other infection.

Now, 4 years later and after doing extensive research into ingredients and reading new research we are adding 1000 IU per capsule of Vitamin D3 (cholecalciferol). That’s the natural form of Vitamin D and the only truly active form. Much research has been done on this once neglected nutrient regarding its power in supporting the human immune system, especially in fighting off colds, flu and other viruses and infections. We believe this will make Virex Complex the supplement of choice in anti-viral, anti-infection and immune system support!
