How magnesium support bone health?
Calcium cannot be optimally utilized without proper balance of magnesium. A high calcium intake without adequate magnesium intake can further drain any reserves of magnesium in the body. Magnesium stimulates hormone calcitonin that helps preserve bone structure by drawing calcium from the blood and soft tissues back into the bones. Sufficient magnesium can help to suppress parathyroid, another hormone that breaks down bone.
Magnesium is also necessary to convert vitamin D into its active form so that it can stimulate calcium absorption. The enzymes metabolizing vitamin D require magnesium as a necessary co-factor. If our body lack of magnesium but we still taking high doses of vitamin D, the increased amount of metabolic activity will drain magnesium from the storage sites.

How type II collagen and glycosaminoglycans (GAGs) affects joint health?
Cartilage is made up of specialized cells called chondrocytes, and it does not have any blood vessels, nerves or lymphatic. These chondrocytes produce large amounts of extracellular matrix composed of collagen fibers, proteoglycan, and elastin fibers. In normal cartilage, it is highly hydrated, being 70% – 75% water. Collagen and proteoglycans account for the remaining dry weight.
Type II collagen represents the largest group of collagen in the cartilage, which account for 90% to 95%. It helps to maintain the tensile strength of the cartilage or resist stretching force on the cartilage.
Glycosaminoglycans (GAGs), which are usually found covalently linked to protein in the form of proteoglycans. The functions of proteoglycan include maintaining the hydration of the matrix, stabilizing the collagen network, and resisting the compressive forces. The main groups of GAGs which covalently attached to proteoglycan includes chondroitin sulphate, keratin sulphate, dermatan sulphate, heparan sulphate and hyaluronan.
In order to have a healthy cartilage, it is very important to maintain the correct composition of water, collagen, and proteoglycan in the cartilage. We can get sufficient of collagen and GAGs through various food and nutritional supplement intake.
