What the name identifies
GELITA markets FORTIBONE for bone health. The ingredient is a specific hydrolyzed collagen peptide preparation, rather than calcium or an osteoporosis medicine. Research about this preparation does not automatically describe every collagen powder. [1][2]
What a controlled trial tested
A 2018 double-blind trial enrolled 131 postmenopausal women with age-related low bone density; 102 completed it, with all enrolled participants included in the intention-to-treat analysis. The comparison was 5 g daily versus maltodextrin placebo for 12 months. Spine and femoral-neck bone density favored the peptide group. The study was partly funded by GELITA; its authors declared no conflicts. Attrition and the specific population matter when applying the findings. [2]
Do not substitute a marker for a clinical endpoint
Imagine a label uses that trial to imply that a powder prevents fractures. The trial measured bone density and turnover markers, not a demonstrated reduction in fractures. Someone being treated for osteoporosis should discuss supplements within their existing care plan rather than replace prescribed treatment on the strength of this result. [2][3]
| Observation | Interpretation |
|---|---|
| BMD improved in a study | Bone-density result |
| Fewer fractures | Requires a fracture outcome |
| Generic collagen powder | Not automatically the tested preparation |
