<<Disclaimer: Verify this information before applying it to your situation.>> <Does anyone know where I can find a GF calcium supplement.> Solgar GF vits are listed on their website....they also have a calcium citrate...if you go to the HFS - a real one, not GNC - you'll likely have a wide selection of calcium supps. Calcium citrate is the best absorbed as Vance said. Another thing that I've found and *love* is an unusual calcium supp. It's actually a fresh water plant and is freeze dried and powdered - so you're taking it like any 'greenfood/superfood' supplement. The plant is called Hydrilla Verticillata, which is also the name of the product 'Hydrilla Verticillata: The Calcium Plant" by a company called Vibrant Health. One tbsp of the powder has 600+ mgs of calcium. Another thing to consider is doing some research on calcium absorption, what affects how much dietary calcium is needed. There are theories out there that say some interesting things - 1) that calcium from dairy is *very* poorly assimilated - and that's why the USRDA is set so high in terms of calcium requirements..because most of us are counting on calcium from dairy - so we need more than we would if we were counting on non-dairy sources (ie almonds, collards, kale, broccoli, sesame seeds, dried figs). Some say that we only need 1/2 as much if we're getting the calcium from these vegetable sources. 2)that the high phosophorus content of animal products (meat and diary) actually cause us to loose calcium. Phosophorus is acidic in the body...which *must* be alkaline to operate properly...so calcium is taken from the bloodstream and leached from the bones (if there's not enough in the bloodstream) to neutralize the phosphorus. So this theory would say that not only does the consumption of animal products negatively affect our calcium balance, but that it also raises are need for calcium to an unusually high level to offset the excretion of said calcium. 3) coffee and soda intake can affect calcium excretion. good article in the last "living Without". Also interesting to note that in heavily meat based populations (look at the innuit) there is a tremendous amount of osteoporosis....Someone is currently doing a longitudinal study in China - on a population where meat consumption is very low - so is diary consumption....osteoporosis is almost non-existent. This is widely reported in the anthropological literature (biological anthro) in many many societies. Other interesting things - even though the women typically spend very little of their lives having fertile cycles (because of pregnancy and extended breastfeeding), and have later menarche and earlier menopause than we do, again osteoporosis is virtually unheard of - even though the women have much lower levels of estrogen throughout their lives because of the above info. Based on our model of osteoporosis, this is suprising, since most american phsyicians feel that estrogen is a huge component of maintaining strong bones. It's interesting that this is not the reality of the non-modern world. So, if you buy into any of these theories and act on them, you may really only need 400-600 mgs of calcium per day. If not, then you need alot more :) katherine in atl
