I have been on Bovine Colostrum and Lactoferrin [capsule] for 6 weeks now and find the 'lift' is continuing with occasional set-backs and re-runs of old symptoms. As I have had CFS/ME for over 25 years I didn't expect fast results.The good thing about it is that it doesn't cause me any digestive problems as most other suppliments do, even although I have an allergy to milk. Please read it up on the net if you are thinking of trying it. Amazon also have several good books on Colostrum. I will continue to post. Love and Light, Deotima.
