I was diagnosed with osteopenia about a year ago. On my Dr’s advice I stopped all calcium supplements and get 1380 mg calcium from my diet. I drink an 8oz glass of “Silk”unsweetened vanilla flavor (I add Splenda) in the am & pm which gives me 940 mg calcium then at lunch I have 2 slices Swiss cheese ((from Sams as not all Swiss provides as much calcium) with a few crackers which gives me another 440 mg. That provides 1380 mg calcium daily. Dietary calcium is absorbed so much better than supplemental tablets but it does need to be spread out during the day) I still get some from my centrum silver but get all I need from dietary sources.
I also take Actonel once monthly! Haven’t had another Deca Scan yet but fingers crossed😊. Hope this helps.
