I've been using CREON for nearly four years but it's currently unavailable in the UK. My Doctor can't even prescribe an alternative as these are also out of stock. I was sent a link for the Grassfed Beef Pancreas & I can confirm it's doing a wonderful job! Thank God for this company!! It has allayed my anxiety & I shall be buying it moving forward. I HIGHLY recommend & give 5*.
Ok I love colostrum and the immune tree are brilliant for me ! I spend an awful lot on supplements but I always have my immune tree colostrum and it definitely improves my immune system , I suffer from Addison's ( major and total adrenal insufficiency) I don't produce any of my own cortisol and it's exhausting even with replacing with hydrocortisone as it's a fixed dose three times daily and not my body regulating the dose. However since I began to take colostrum every day I have indeed noticed some increase in stamina and definitely improved immunity. I'd highly recommend this colostrum to any one and everyone wanting that extra boost for the immune system.

Take the mucus-melting, phlegm-expelling properties of Free The Lungs, combine with the cough-disappearing effect of Golden Air, add the ability to breathe deeper, and I still would not have encapsulated all the benefits that Young Lungs seems to provide.
