Summary

This study tested whether a supplement made from salmon bone powder (CalGo) could help prevent bone loss in perimenopausal women with low bone density. Eighty women aged 50 and older took either the supplement or a placebo for up to 24 months. Researchers measured changes in bone density at the hip, spine, and forearm to see if the supplement slowed bone thinning.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: salmon bone meal (CalGo) with vitamin D3
What this could lead to: If it works, this could provide a natural dietary supplement to help maintain bone density in women at risk for osteoporosis.
What could go wrong: This is a small, completed trial with 80 participants. The supplement may not significantly slow bone loss, and results may not apply to all women.
