Bone CoFactors by Douglas Labs
Supports bone strength
Bone CoFactors is formulated to provide the necessary vitamins and minerals combined with a milk protein fraction called MBP® that helps to support bone strength. MBP has the distinctive function of balancing osteoblast and osteoclast activity, which complements the function of other nutrients in Bone CoFactors for optimized bone health.†FUNCTIONS Bones are constantly being remodeled, not only during the growth stages, but also into adulthood. This process of bone turnover involves two types of cells: osteoblasts and osteoclasts. Osteoblasts promote bone formation and create collagen, so that calcium can effectively adhere to the collagen and create new tissue. Osteoclasts destroy old bone tissue by releasing acid and enzymes to dissolve calcium and collagen. However, osteoclasts can become excessive due to hormonal imbalances and other factors, leading to calcium deficiency in the bone. Therefore, nutrients that suppress excess osteoclast activity and support osteoblast activity are important to the health of the bones.
MBP is a milk protein fraction that is found in human and bovine milk and has been clinically shown to support the formation of healthy bones. It is a highly bioactive fraction of total milk protein content consisting of 97.2% lactoferrin and lactoperoxidase, with the remaining 2.8% as other milk proteins, cystatin C, HMG-like protein, and kininogen fragment 1.2. Unlike other bone substances such as Vitamin K, MBP increases the number of bone-forming osteoblast cells and regulates the activity of bone-destroying osteoclast cells. Therefore, MBP is a multifunctional protein that functions by acting directly and/or indirectly on bone cells to promote the bone formation, while at the same time inhibiting excess bone destruction, called bone resorption. Because bone metabolism proceeds at an extremely gradual pace, it may take 3 to 6 months or longer to notice improved bone metabolism with supplementation.
In a study conducted with 33 healthy adult women, BMD (bone mineral density) increased by 3% in the control group after 6 months of ingesting 40 mg of MBP® daily. Vitamin D helps to facilitate calcium absorption and transport. Vitamin D can increase the expression of osteocalcin and other important compounds from osteoblasts to help support bone formation; it can also help to breakdown bone and mobilize calcium to other tissues in the body. Numerous scientists now feel that supplementation with vitamin D at levels greater than previously thought necessary is critical to helping maintain healthy bone remodeling as we age.†
Vitamin K2 is not commonly found in the diet. Human studies show that vitamin K plays important roles in bone health; it has been shown to decrease calcium excretion and is involved in gamma-carboxylation of osteocalcin. Osteocalcin, a protein found in the extracellular bone matrix is important for healthy bone formation as it facilitates the carrying of calcium out of blood vessels and binding it to hydroxyapatite (bone matrix). Vitamin K2 (as menaquinone-7) is more bioactive and has proven more effective than vitamin K1 and other menaquinones. Furthermore, the study showed better utilization and improved osteocalcin carboxylation for MK-7 after 6 weeks.
Calcium Microcrystalline Hydroxyapatite provides a highly beneficial source of dietary calcium together with other naturally occurring nutrients like phosphorus, amino acids, glycosaminoglycans that assist in the maintenance of healthy bone structure and function.†
Boron affects the composition, structure, and strength of bone. It appears to be necessary for calcium and magnesium absorption, their adequate renal reabsorption, and their incorporation into the bone matrix.
Magnesium is a mineral that is important for normal bone structure, and plays an essential role in more than 300 cellular reactions.† New research shows magnesium homeostasis is helpful for maintaining bone integrity.
Vitamin D and parathyroid hormone are essential for magnesium absorption.
Trace minerals such as zinc, manganese and copper are also important for bone health. Some clinical research suggests that taking copper in combination with zinc, manganese, and calcium may support healthy bone metabolism in postmenopausal women.† Low serum zinc levels have been associated with low bone mineral density.
