Researchers in Brazil report that prolonged use of the proton pump inhibitor (PPI) omeprazole altered iron and calcium measures in adult rats and shifted how several minerals were distributed across organs—changes they say are consistent with higher risks of anemia and possible bone health harms. The authors and Brazil’s health regulator stress that PPIs remain effective for acid-related disorders, but warn against extended, unsupervised use.
Scientists at the University of Hong Kong have uncovered a protein that acts as an exercise sensor in bones, explaining how movement prevents age-related bone loss. This discovery could lead to drugs mimicking exercise benefits for those unable to stay active. The findings highlight potential new treatments for osteoporosis affecting millions worldwide.

A 10-year study of nearly 10,000 women aged 65 and older found that regular tea drinking was linked to slightly higher bone mineral density, a key marker of osteoporosis risk. Moderate coffee intake showed no overall harm, but consuming more than five cups a day was associated with lower bone density, particularly among women who reported higher lifetime alcohol use, according to researchers from Flinders University.
