Guest guest Posted February 12, 2008 Report Share Posted February 12, 2008 Hi, I just wrote and email to Forest Pharm. about the use of calcium sterate in Armour tablets themselves, and asking about other element interactions. I would like to get hard data on interaction times (delays) for element/mineral supplements. I assume it is too low to cause an interaction, as Armour obviously does wrk (although my question is - could it work *better* if there were no Ca in it at all..) I plan to call them if I don't get a response. The email to Forest is below, Jim ---- (email to Forest) I have read (but not found what I consdier to be definitive info) that calcium (as well as iron) interferes with thyroid hormone absorption in the gastrointestinal tract, leading to a " generally accepted " practice of waiting 1 hour after taking Armour to take calcium and 4 to take iron - although one person said they could not find a Ca supplement that did not interfere even when seperated by *12* hours) What is the " lower limit " of Ca and Fe intake that will interfere, and are there any other elements that will? I assume there is a lower limit for Ca, as calcium stearate is an inactive ingredient for Armour itself, and the drug obviously works.. Particularly, in addition to Ca and Fe, will selenium, magnesium, potassium, and titanium interfere? I know Se is found in the de- iodinase enzmes and I presume may be required for the removal of iodine in the T4->T3/RT3 conversion, and is also a useful supplement as it has been shown to reduce TPO and TgAb concentrations (PMID 11932302 and 14757967), and magnesium is often deficient (so I have read) in persons with hypothyroidism, and so is often supplemented. Potassium is found in just about everything these days it seems, and titanium is used ubiquitously in the white dye titanium dioxide in many pharmaceuticals, including Armour. In my opinion , TiO2 is totally uncessesary, and should be removed as while titanium is not known to cause any problems with the human body, and generally stays bound in TiO2 form due to it's high reactivity, it is not known *not* to cause any negative interactions either. It is in everything, so there is no suitable control population in which to look for adverse effects) I personally use a selenium supplement (Nature's Bounty - high Se yeast 200mcg) which contains dicalcuium phosphate as the first ingrident (I delay before taking that in case it's Ca concentration is too high). I am not however certain about Ca in my antidepressant and antianxiety drugs - generic buporpion (75 mg), supplied by Teva, NDC 0093-0280-01; and lorazepam 1 mg, supplied by Pedinol Pharm. I cannot find a reference to generic Lorazepam made by Pedinol, but the previous supplier of my pharmacy (Mylan) has NDC 0378-2321-[01/05/10 depending on bottle size]. It's inactives are: lactose monohydrate, microcrystalline cellulose, polacrilin potassium and sodium stearyl fumarate [1]. The burpropion contains as inactives: colloidal silicon dioxide, FD & C Blue No. 2 Aluminum Lake, FD & C Yellow No. 6 Aluminum Lake, glutamic acid hydrochloride, hydroxypropyl cellulose, hypromellose, magnesium stearate, maleic acid, microcrystalline cellulose, polyethylene glycol 400, polyethylene glycol 6000, talc, and titanium dioxide. I am not certain either of these contain Ca. (assumming Pedinol uses the same inactives, which I assume it does) Thank you, Jim Witte [1] Lorazepam: http://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?id=4145 [2] Burproion: http://dailymed.nlm.nih.gov/dailymed/drugInfo.cfm?id=2773 ---- Quote Link to comment Share on other sites More sharing options...
