A nutritional intervention study with hydrolyzed collagen in pre-pubertal Spanish children: influence on bone modeling biomarkers
Abstract Aim : The aim of the study was to investigate the influence of dietary intake of commercial hydrolyzed collagen ( Gelatine Royal ® ) on bone remodeling in pre-pubertal children . Methods : A r and omized double-blind study was carried out in 60 children ( 9.42±1.31 years ) divided into three groups according to the amount of partially hydrolyzed collagen taken daily for 4 months : placebo ( G-I , n=18 ) , collagen ( G-II , n=20 ) and collagen+calcium ( G-III , n=22 ) groups . Analyses of the following biochemical markers were carried out : total and bone alkaline phosphatase ( tALP and bALP ) , osteocalcin , tartrate-resistant acid phosphatase ( TRAP ) , type I collagen carboxy-terminal telopeptide , lipids , calcium , 25-hydroxyvitamin D , insulin-like growth factor-1 ( IGF-1 ) , thyroid-stimulating hormone , free thyroxin and intact parathormone . Results : There was a significantly greater increase in serum IGF-1 in G-III than in G-II ( p<0.01 ) or G-I ( p<0.05 ) during the study period , and a significantly greater increase in plasma tALP in G-III than in G-I ( p<0.05 ) . Serum bALP behavior significantly ( p<0.05 ) differed between G-II ( increase ) and G-I ( decrease ) . Plasma TRAP behavior significantly differed between G-II and G-I ( p<0.01 ) and between G-III and G-II ( p<0.05 ) . Conclusion : Daily dietary intake of hydrolyzed collagen seems to have a potential role in enhancing bone remodeling at key stages of growth and development
