vitamins/supplements/environmental nursing is somewhat my thing! christine is right about the tums. doctors don't always know good advice in this field. taking tums(calcium carbonate) is not a good calcium supplement. calcium carbonate is the least absorbable,least digestable calcium available. plus it decreases the hydrochloric acid in your stomach of which you need that to digest your food. if heartburn,GERD,etc is a problem,start on a good digestive enzyme(you are not digesting your food well). the best calcium supplement is finding a formula with 2-3 kinds of calcium in it along with magnesium,phosphorus,boron,and vit. D. Boron is the bone knitting mineral here that is all important!this type of formula will go to the bones where needed. milk is not a good source of calcium due to it lacking some of the above. i am not a believer in centrum vitamins either. yes i know everyones doctor recommends them! i do not agree at all! they are synthetic vitamins that don't get absorbed properly. (kinda like the synthetic hormones that doctors give out too-the recent big study on hormones did not surprise me in the least). studies have shown taking synthetic vitamins like centrum develop "expensive poop" and found at the bottom of outhouses,port a potties,etc. invest in a natural multi-vitamin. vit.E (get natural again-not synthetic!) is a natural blood thinner and good for the heart. a natural vit.e can be determined by looking at the label. does it say D or DL alpha tocopherol? D is the natural. DL stands for darn lousy and is synthetic. read label carefully as the l in dl blends in well. coumadin levels would need to be adjusted but then again do you want to take vit.e or coumadin in bigger doses? i would prefer to take vit.e daily and have the coumadin dose adjusted around that. kinda like the dietary adjustments one does also if inr is low or high. To get true healing of any disorder, one needs to invest in natural stuff that gets to the cells of the body to do any good. of course some natural herbs,etc. do need to be avoided to those on coumadin. that subject has been talked about in the past. hope this helps on the vitamin/calcium mystery. if personal questions, email me privately. i don't sell over forums. just wanted to give basic info to those interested. stay healthy!!
