New Study Demonstrates the Effect of Collagen Peptides on Bone Turnover in Postmenopausal Women with Osteopenia

Osteopenia

Researchers investigate the efficacy of collagen on postmenopausal women with osteopenia

Collagen has been garnering much attention in regards to its wide array of benefits, often with the spotlight on bone and joint health. In a new study published last month, researchers investigated the efficacy of specific collagen supplementation on body turnover in postmenopausal women with osteopenia.

Type 1 collagen makes up 95% of collagen content of bone

Postmenopausal women have an increased risk of osteoporosis due to breaking down old bone tissue faster than it can be replaced. Type 1 collagen makes up about 95% of the collagen content of bone and previous research had shown its involvement on the properties of bone.

Studyof postmenopausal women with osteopenia on the effect of collagen supplementation to their bone mineral density

This was a randomized prospective study consisting of 51 postmenopausal women with osteopenia based upon bone mineral density measurements of the lumbar spine and femur using dual energy X-ray absorptiometry (DXA). These patients were divided into two groups. Supplementation in 24 individuals consisted of 5 grams of collagen peptides, 500 mg of calcium, and 400 IU of vitamin D. The other group consisted of 27 individuals supplemented with the same dosage of calcium and vitamin D only. Laboratory assessment included procollagen type 1 N-terminal propeptide (P1NP) and C-terminal telopeptide of collage 1 (CTX) levels. These samples were collected at baseline and at 3 months. Other laboratory testing was conducted to rule out secondary causes of osteoporosis such as serum calcium, parathyroid hormone, and vitamin D 25-OH.

Researchers demonstrate the efficacy of collagen peptide supplementation to decrease the bone’s P1NP and CTX levels  and improve the bone metabolism in postmenopausal women with osteopenia

As a result, there was a significant decrease in P1NP levels by 13.1 % and CTX levels by 11.4% in the collagen peptide supplementation group over a 3-month period. No changes were seen in the other group that only supplemented with calcium and vitamin D. Collagen peptides affect the remodeling and mineralization of the bone matrix and enhance osteoblastic differentiation. These results demonstrate the positive effects collagen peptides on bone metabolism in postmenopausal women with osteopenia.

Collagen as a significant part of the human body’s composition

The body is not only composed of complete proteins, but is 25% to 30% collagen. Collagen protein is renewed at comparable rates as other proteins in the body, such as in bone. It is important to note that collagen also makes of a significant component of many tissues such as 65% to 80% in tendons, 70% in ligaments, 50% in cartilage, and 23% in cortical bone.

The many benefits of quality collagen supplements backed by research

Other potential benefits of collagen supplementation include helping with skin health, and sarcopenia, as well as supporting healthy blood pressure and a normal insulin response. It is important to use a quality collagen supplement that has research behind it and is a low molecular weight to optimize absorption and efficacy. Additional nutrients to help support osteopenia include vitamins D and K, magnesium, genistein, and delta and gamma tocotrienols.
