Lactoferrin: Promising Strategy for Better Bone and Joint Health - Combats Osteoporosis and Osteoarthritis

Over the last ten years, lactoferrin, a natural bioactive glycoprotein from milk, has stirred considerable interest in the field of bone health. (1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16) Lactoferrin limits inflammatory messenger molecules to reduce inflammation and reduce catabolic (tearing down) activity in the body. This includes a calming down of the destructive action of osteoclasts, the cells responsible for excessive bone resorption that leads to osteoporosis. This anti-catabolic effect not only helps people with osteoporosis but it also prevents the cartilage degradation seen in people who suffer from osteoarthritis. (17,18)

Lactoferrin, a multifunctional protein of the innate immune defense system.
Now, with solid evidence (19,20,21) that lactoferrin also enhances anabolic (bone building) activity in bones, it is currently one of the hottest and most promising neutraceutical on the market for combating osteoporosis. Lactoferrin's anabolic (building) effect on bone stems from its ability to reduce inflammation and osteoclastic activity, and also by improving osteoblast cell activity for enhanced bone formation.

Lactoferrin is one of those few molecules that is known to effect both the osteoclasts and the osteoblasts in the remodeling activity of bone...AND it is NOW in OsteoStim. OsteoStim already includes a stellar list of natural vitamins, herbs, and bioactive ingredients shown to help balance bone remodeling through a reduction in osteoclastic activity and a boost in osteoblastic bone-building action. This OsteoNaturals product has just gotten better.
