I too have PMR, did 15 months of Prednisone and am currently in remission. I am in my 70s and have osteopenia so my calcium intake has always been important to me. I increased my daily calcium to over 200% of the recommended daily requirement. I take supplements but also discovered almond milk! 8 oz contains 35% of your daily requirement. Since I was looking for food rich in calcium, I also discovered that a simple 1" by 1" of asiago cheese has 20% daily requirement. Tums are also a good source of calcium. I had a dexa scan just before being diagnosed with PMR and then I had a dexa scan after stopping Prednisone. All of my bone density numbers were in the plus column! Hurray! I took my calcium supplement in the morning then supplemented my calcium throughout the day. I don't know if that was important but I think it worked at maintaining my bone density.
