My first DXA scan was in May, 2007 (diagnosed with
osteoporosis):
Spine from L1-L4 T-score -3.0
Left hip (total) T-score -2.2
Left femoral neck T-score -2.8
My second DXA scan was in July, 2009 (After 6 months on
Fosamax once weekly and 18 months on strontium citrate, 680 mg strontium daily,
still at osteoporosis, but scores improved):
Spine (total) T-score -2.7
Left hip (total) T-score -1.7
Left hip (neck) T-score -2.6
My third DXA scan was in August, 2013 (After 5 ½ years on
strontium citrate, scan results were at the osteopenia stage; I was probably at
the osteopenia stage before this, but I did not have a DXA scan in 2011):
Spine from L1-L4 T-score -1.6
Left hip (total) T-score -1.4
Left hip (neck) T-score -1.4
Osteopenia is defined as T-scores < -1.0 and -2.5.

Thank you for continuing to post such useful information.
After 4 years of Strontium supplementation, my DXA scan has shown improvement from significantly deteriorating Osteopenia to a Normal scan... I have tried to find information as to making a dose reduction but can find none. I take 227 x 3 at bedtime, 2 - 4 hours away from food/CA supplements. Do you know of a reference to guide me as to a modified regimen? thank you for any assistance.
Sharon,
As you can see from my most recent DXA scores, as of August, 2013, I was in the osteopenia stage and getting pretty close to normal. I may be in the normal range by now, and, like you, may soon need to make a decision about whether or not to reduce my dosage. I did not reduce the dosage when my BMD improved from osteoporosis to osteopenia.
From the PREVOS and STRATOS studies, we know the minimum effective doses of strontium ranelate (SR) for treating early postmenopausal non-osteoporotic women and postmenopausal osteoporotic women are 1 gram/day and 2 grams/day, respectively. One gram of strontium ranelate contains about 340 mg elemental strontium, and two grams SR contains about 680 mg strontium.The link to this abstract is on my blog under “For More Information about Strontium.”

Your question is what dosage of strontium citrate (SC)should be taken to maintain the normal BMD obtained after four years on 681 mg strontium/ day. This question falls into a gray area. I cannot direct you to a clinical study that answers it. I can only give you my opinion.
After my next DXA scan, if I am in the normal BMD range, I plan to reduce my dosage to 340 mg strontium daily. I believe that is a good maintenance dose because it is the amount recommended for early postmenopausal non-osteoporotic women. I was a postmenopausal osteoporotic woman prior to taking SC.
Since your SC comes in 227-mg capsules, you could drop to one capsule per day.
