Guest guest Posted August 19, 2002 Report Share Posted August 19, 2002 Hello Guy & * Calcium citrate may have a longer half life in the blood, it may get there faster, however the purpose of supplementation in this case is to increase bone density. * Therefore the calcium hydroxyapatite supplement would be preferred for cases of osteopenia because it is shown to increase bone density, whether or not it stays in the blood longer. * it does not what the blood levels, absorption rates, etc., were when you want the patient to have increased bone mass. ===> 1st, calcium citrate has been proven to be safe and effective for helping patient with osteoporosis. It is also has been shown to increase bone density in younger and older population. ===> 2nd, it is important to know whether oral supplement have good absorption rate. That is why we as doctors need to investigate a trustworthy company before we recommend their products to our patients. If we don't do this, how can we explain to patient the difference between a $25 Calcium supplement we sell in our clinic to that of a $6 Calcium supplement they get from Costco (Kirkland is the company)? ===> 3rd, what's the difference between hydroxyapatite, calcium from oyster shell, calcium oxalate, calcium carbonate, and calcium citrate? We need to know their difference! Calcium citrate not only has good absorption rate (especially taken after meal) but only increase plasma calcium concentration (calcium in blood, that is) for a long time. This is significance when you understand they physiology of bone resorption. When plasma calcium concentration decreases (hypocalcemia), PTH (parathyroid hormone) is released to increase bone resorption activities...and thus normalize the plasma calcium concentration. However by doing so, bone lose calcium and patient suffers osteoporosis. The longer half-life of calcium citrate in blood decreases PTH level and thus prevent or slow down the bone resorption rate. *Jim Shattel at Metagenics Midwest would have the explicit details on this particular study if you want to contact him. His supplement company is one of the best I have seen for nutritional products of the Western variety. ===> 4th, I am very familiar with Metagenics. It is one of the many companies that not only provide the nutiritional products, but it also provides seminars to teach " doctors " how to use their products. However...I am trying very hard to be diplomatic here...herbal/nutritional companies, in general, have their own agendas when they offer these seminars -- the bottom line is to increase product sales. The difference between herbal companies and pharmaceutical companies is that herbal companies charge fees for their seminars while pharmaceutical companies pay doctor dinner and give drug samples to attend their seminars. Therefore, I suggest that we, as responsible doctors, should use our knowledge and judgement rather than blindly believe all these so-called " experts " at the seminar...such as the case of deke kendall...oooop! did I just open another can of worm? ;-p ===> Hydroxyapatite is a bigger molecule than calcium citrate...and therefore does not absorb in the intestine as well as smaller molecule. humbly yours, Thomas ** The true measurement of success is not how many servants one has, but how many people one serves ** HotJobs - Search Thousands of New Jobs http://www.hotjobs.com Quote Link to comment Share on other sites More sharing options...
