Dr Keith McCormick recommends collagen as well, in his book Great Bones. He claims that type 1 collagen is best for bones. He has formulated a collagen product specifically for bone health. You can find it on http://www.osteonaturals.com. it's called Osteo Collagen Pep with fortibone. I have been using it for months and really like it. It's unflavored and mixes with anything. Not sure what it's doing for my bones, but it's a great collagen supplement. Good luck!
