Hi, Becky, I have just been told my PSA has gone down from 15.5 to 7.7. The nurse asked me what I have been doing to make this happen. Supplements, I have to presume: Liposomal mixture - sunflower lecithin, vitamin C, curcumin & sprouted broccoli powder; Patrick Holford Multivitamin; a tincture from my herbalist of - nettle root, reishi, artichoke and equisetum; vitamin D3 4000IU; Mushroom complex; garlic capsules; magnesium; plus occasional B complex and selenium. I need to stress that, despite my Herbalist's admonitions, I am not completely consistent and occasionally miss a day entirely! I don't suppose a research scientist would be content with my description, lacking scrupulous figures but ... something is working!
