I've been on this combo for two weeks now and have, for the first time in my quest for health, felt significantly better. Less joint pain, more fluid movements, a little more energy, and a slight increase in mental sharpness. The fat soluable vitamins are good for the brain. I'm especially impressed with how my feet have improved. I limped for years and they felt as is they were made of glass. I felt a huge difference in three days. It did what Dr. Price and others have claimed for them. I'm totally convinced that the human body needs these basic nutrients. Great stuff!
