Bones are the living mineralized support tissue of the body. They are constantly being made and unmade and made again. This process in carried on by bone cells called osteoclasts and osteoblasts. The osteoclasts function to dissolve older bone and leave tiny unfilled spaces behind. Think of them like pacman that search around to gobble up old bone and leave a small space like a little pond. The osteoblasts (Mario Brothers) then move into these spaces and produce new healthy thicker bone.
Progesterone helps to stimulate the osteoblasts (Mario Brothers) to make new bone which helps to prevent and reverse osteopenia or osteoporosis. Natural estrogen only helps to slow down the osteoclast (pacman). It doesn't do anything to the osteoblasts and does not make new bone.
Although estrogen is known to decrease in menopause, progesterone levels may drop to near zero in some women. Often this is because adrenal glands utilize progesterone to manufacture the stress hormone cortisol. Continuous stress creates a constant demand for cortisol which reduces your levels of progesterone.
Natural progesterone cream is the identical hormone that is produced by a woman's ovary. It is made from naturally occurring plant steroids found in the wild yam and whatever your body doesn’t need it gets rid of. It also balances excess estrogen (dominance) which can be a major risk for breast cancer. You just apply ¼ tsp of Natural Progesterone to the skin (abdomen, neck, side) 2x day and rotate to a different spot every now and then so the skin can absorb it better.
Synthetic (prescription) forms of progesterone, called progestins (Birth control pills, Aygestin, Provera, etc.), do not have the ability to stimulate the osteoblasts, therefore cannot stimulate bone growth, is stored in your tissues and increases the risk of heart disease, stroke and cancer.
So if you want to improve your bone density I suggest: Get on a complete bone formula, regularly do weight bearing exercises, adjust your diet and start using Natural Progesterone cream! (I use NPC cream located on this website, holistichealthline.com, if you want more information)
