I hear nothing but good things about Primal Defense and what it can do. Try adding the greens that are offered by the same company. Also, there is a product that I love, A*****ose from M****tech Inc. This product is the most amazing product on the market today. It was developed by doctors and it has healed so many ailments for me. I no longer get sick, no more allergies and no more candida, thank God. Yes, your body (immunity) needs to be stong to heal and it will when you give it good things. I'm a true believer, I'm my own testimonial. Go to Glycoscience.com and read all the Science behind this product, you'll be amazed of the healing properties. I wish you great health................Heather
