Calcium hydroxyapatite formula

Hydroxyapatite (HA) is an inorganic mineral present in human bone and teeth. It plays a role in the structural strength of bone and in bone regeneration. While it occurs naturally in bone, healthcare professionals often use synthetic and natural HA when carrying out bone repair treatments. Bone diseases and bone abnormalities are When bone loss occurs, the body will often replace this lost bone through bone regeneration. This process is the name for the production of new bone. HA plays a role in natural bone regeneration. It is also a possible treatment option to help doctors stimulate bone regeneration when treating bone loss. HA Crystals of HA are present in bone in the shape of plates or needles. These crystals are around 40–60 nanometers (nm) long, 20 nm wide, and 1.5 to 5 nm thick. The arrangements of these HA crystals can vary in number, size, and shape. These arrangements provide support for the bone’s: • structural stability • hardness • function Bone damage These diseases and abnormalities • trauma and injury • • • degenerative conditions • Bone regeneration is the process where bone may HA plays an essential role in bone regeneration, of which there are two key processes: • Osteoinduction: This is the name for the process that induces new bone production. It involves the transformation of immature cells into preosteoblasts, which are important cells in the formation of new bone. • Osteoconduction: This is the term for the ability of bone-forming cells to HA HA oc...

Answer: It is important to get an adequate amount of calcium, as it is essential to maintaining your bones and plays critical roles in nerve transmission, muscle contraction, and your cardiovascular system. Calcium is best obtained naturally from foods, but supplementing with calcium can help when intake is otherwise not sufficient, but getting too much calcium from supplements is associated with certain risks. How much calcium do you need? For women over age 50 and men over age 70, the recommended daily intake of calcium is 1,200 mg from food and supplements combined — although it's best to get most of this from foods. For women under 50 and men under 70, it's 1,000 mg daily, while for older kids and teenagers it's 1,300 mg. If you can get most of it from food, then it's best to limit your intake of calcium supplements to just the amount you need to meet the recommended intake. To get an idea of how much calcium is in common foods, see How much calcium do you already get from food? section of the Calcium Supplements Review. Experts believe that one can't absorb more than about 500 mg of calcium at time, so foods or supplements with higher doses may provide too much calcium. For instance, if you drink a cup (8 fl oz) or more of milk that is fortified with calcium at a time, this milk may provide you with too much calcium. On the other hand, a cup of lactose-free milk that is not "calcium fortified," will naturally provide about 30% of the Daily Value for calcium (390 mg ba...

Answer: OsteoMD by 1MD is a bone health supplement that, according to its website, "is proven to help support strong bones by stimulating mobilization of calcium to slow the rate of bone loss, and may reduce the risk of osteoporosis." It contains a combination of ingredients that are commonly included in bone health supplements, such as vitamin D, calcium and vitamin K2, as well a lesser-known ingredient — Cal-Z-Bone, a branded extract of Cissus quadrangularis, a plant in the grape family. The OsteoMD formula does not appear to have been tested in a clinical trial. So, instead of reviewing data for the product, we reviewed the amounts of each of its ingredients for potential efficacy and safety. OsteoMD Ingredients: Vitamin D3 OsteoMD contains 50 mcg (2,000 IU) of vitamin D3 per three-capsule serving. Taken with calcium, vitamin D can help decrease post-menopausal bone loss and prevent osteoporosis (loss of bone density), but 2,000 IU is more than typically needed -- the if a person's blood level of vitamin D is already close to or above 20 ng/mL, taking a vitamin D supplement provides no further bone benefit. While the amount of vitamin D in this product may provide a bone health benefit in people with low levels of vitamin D, be aware that having blood levels of vitamin D above 50 ng/mL, and/or Calcium OsteoMD contains 325 mg of calcium, as Calcium hydroxyapatite is derived from cow bone, and naturally contains other minerals, as well as bone proteins such as collagen.

Hydroxyapatite Hydroxyapatite (HA) is a naturally occurring mineral form of calcium apatite that shows good biocompatibility and is an excellent candidate for bone repair and substitution. From: Nano Today, 2014 Related terms: • Apatite • Biomimetics • Calcium Phosphate • Chitosan • Graphene • Nanoparticle • Nanocomposites • Nanofibers • Hydrogel • Carbon Nanotube R Z LEGEROS, J P LEGEROS, in Bioceramics and their Clinical Applications, 2008 Publisher Summary Hydroxyapatite (HA or HAP) of biologic (coral-, bovine- or marine algae-derived) or synthetic origin are currently used for bone repair and bone regeneration in the form of granules, blocks and scaffolds, by itself or as composite with polymers or other ceramics or as coatings on orthopedic or dental implants. They are commercially available for use in bone repair, substitution, and augmentation and as scaffolds in tissue engineering for bone regeneration. The rationale for its development as a bone substitute material is its similarity in composition to the bone mineral. HA is also used as abrasives to roughen metal implant surfaces and as source material for depositing bioactive coatings on orthopedic and dental implants. These materials can also be used as transfection agents, drug carriers, and percutaneous devices. HA- or HAP-based biomaterials with improved properties included substituted apatites. This chapter presents an update of previous reviews on apatites and focuses on its preparation, properties, cell an...
