I am a pharmacist and also a practicing naturopath and fully aware of the available options on both sides. I cannot say enough about Curcumin and its many many benefits from Cancer to inflammation and beyond. There are many companies selling this product and about an year I finally landed with the right company. I recommend and sell three of these Curcumin products to most of my clients and I receive excellent feedback from them. I am extremely satisfied with the purity and value and excellent service these guys provide. Physician Naturals have the best line up of pure Curcumin Turmeric supplements and they only use Curcumin C3 Complex.
