Rating (out of 5): 3

Hydrolyzed gelatin, also known as collagen hydrolysate, has been investigated for its potential benefits to the skeletal system, particularly bone health. Gelatin is rich in collagen-derived peptides, which are important components of bone matrix. Several studies have explored whether oral supplementation with collagen or hydrolyzed gelatin can positively affect bone metabolism and integrity. Some clinical trials and animal studies indicate that hydrolyzed collagen may help increase bone mineral density or slow bone loss, especially in postmenopausal women or individuals at risk for osteoporosis. For example, a randomized controlled trial published in Nutrients (2018) reported that daily collagen supplementation improved bone mineral density in postmenopausal women. Mechanistically, collagen peptides may stimulate osteoblast activity and enhance the synthesis of bone extracellular matrix.

However, while these findings are promising, the overall body of evidence is moderate, with some studies showing benefit and others reporting minimal effects. Most studies are relatively small, and longer-term data are still limited. Therefore, while there is a scientific basis and some validation for the use of hydrolyzed gelatin to support bone health, the strength of evidence is not definitive, warranting a moderate rating. It is not purely a traditional remedy, as modern research is the main source of its claims related to the skeletal system.
