Hi Colleen; Yes it is but it is being taken under my Dr.'s supervision out at the Mayo Clinic in MN. I was also told to take 2000 IU of Vitamin D3 since the high dose can affect calcium uptake. I return to Mayo every 3 months for a "Scope" and next due for one the beginning of May. Hopefully the high-grade dysplasia has been reduced since I don't know how many times I can get a Mucosal resection before I would need the nodules and the surrounding area of the stomach cut out which would mean major surgery.
