Hi Phil, good to hear from you! I really enjoyed meeting you and all the others in Virginia. > We also informed the directors at the assisted care living facility > where my mother is a resident about the B12 calcium connection. My > mother suffers from dementia and takes Oscal three times a day. We'll > have to see if switching her to Calcium Citrate will have any affect. If there is a connection between her dementia and B12, it would be far better that she have regular B12 shots. A lab test should be able to determine a deficiency; however, some physicians order B12 shots if they suspect a deficiency. If the dementia has not progressed too far, B12 may reverse it. I will hope for good results for your mother.
