Wassen Selenium-Ace contains essential traces of the mineral selenium and Vitamins A, C, and E which acts as an antioxidant and helps you to maintain a healthy immune system, and neutralise harmful substances in the body called free radicals.
I have been taking Wassen Selenium for 5 years now basically because I had bladder cancer and have a large prostate. I have taken other selenium supplements before plus other supplements for colds etc but I have found Wassen to be the best as my regular check up at the hospital is always alright!....Before when I was going back and forth to the hospital I always had small growths in the bladder. In summary I would highly recommend this particular brand!!
