Tauroursodeoxycholic acid (TUDCA) is a metabolite of Ursodeoxycholic acid (UDCA), a commonly prescribed treatment for cholestasis. TUDCA is the best and most cost-effective option for gainers seeking ultimate liver protection. As an endogenous bile acid, TUDCA encourages natural bile flow and inhibits the formation of toxic steroid metabolites - the stuff that causes bile blockage in the first place! No wonder TUDCA is a favorite among athletes. Unlike Milk Thistle or N-Acetyl A-Cysteine (NAC), TUDCA offers optimum liver health protection specifically for those who have taken, are taking, or plan to take oral performance enhancement products, which are infamous for inhibiting the production and flow of bile from the liver. This effect is known as cholestasis. Build up of high toxic levels in the liver from toxic metabolites can lead to cell damage and even death. Without bile flow to remove toxins, your days in the gym (and above ground) are numbered. It's that simple. When it comes to cholestasis, your liver isn't the only vital organ placed at risk. Elevated LDL (bad cholesterol) and decreased HDL (good cholesterol) may also occur. This dangerous combo leads to an increased risk of heart disease. See why liver health protection and maintenance is so important?
