Collagen peptides may improve bone health in osteopenia Original paper
This Study Summary was published on September 4, 2020.
Background
The study
In this 3-month randomized controlled trial, 52 postmenopausal women with osteopenia (reduced BMD often associated with aging) were divided into two groups. Both groups took comparable amounts of calcium and vitamin D. One group also took 5 grams of collagen peptides (aka hydrolyzed collagen), while the other took a placebo.
The results
Collagen peptides improved bone turnover (i.e., bone formation) in women with compromised bone health.
Note
The sample size was small and the duration short. Moreover, since all the participants had osteopenia, we don’t know how collagen peptides would affect bone health in people without this condition.
