Osteoporosis stands out as a prevalent skeletal ailment, prompting exploration into po-
tential treatments, including dietary strontium ion supplements. This study assessed the efficacy of
supplementation of three strontium forms—strontium citrate (SrC), strontium ranelate (SrR), and
strontium chloride (SrCl)—for enhancing bone structure in 50 female SWISS mice, aged seven weeks.
In total, 40 mice underwent ovariectomy, while 10 underwent sham ovariectomy. Ovariectomized
(OVX) mice were randomly assigned to the following groups: OVX (no supplementation), OVX +
SrR, OVX + SrC, and OVX + SrCl, at concentrations equivalent to the molar amount of strontium.
After 16 weeks, micro-CT examined trabeculae and cortical bones, and whole-bone strontium content
was determined. Results confirm strontium administration increased bone tissue mineral density
(TMD) and Sr content, with SrC exhibiting the weakest effect. Femur morphometry showed limited
Sr impact, especially in the OVX + SrC group. This research highlights strontium’s potential in bone
health, emphasizing variations in efficacy among its forms.
