Hi everyone. I am going to pass off my daily calcium supplementation program: 1 eggshell(with meal #1) 1 eggshell/1 500 mg. calcium carbonate tablet with 150iuVitD3(with meal #2) repeat same dose for meals #3 and #4. Total calcium 'per diem'=2000-2500mg. Does anyone think this is an excess for someone who: works out daily(resistance exercise + load bearing cardio, eg.walking at fast pace 1 hr.) doesn't consume more carbs than 50 grams per day consumes supportive nutrients such as magnesium, phosphorous(possibly too much), vit D, A, C and lots of saturated/monounsturated fat, minimal PUFAs and who consumes 2-3 tbsps of vinegar/lemon juice prior to each meal
Should I reduce the calcium as I am worried/concerned about calcification of soft tissues in the body. I like the ergogenic quality of calcium so I keep it fairly high relative to what I have come to understand as 'Normal'. I have been following this dietary regime for at least a decade now(at least so far as calcium is concerned). Calcium carbonate quality is alleged to be lesser than citrate: is it fine to stick with the carbonate for best absorption? Would the phosphorous in eggshell/animal bones reduce absorption drastically? Can one consume a large amount of calcium in the form of animal bones/eggshell in tandem with the other naturally occuring nutrients like phosphorous and have it result in a lesser effect than supplemental calcium(eg. pills, liquids, etc.). What would be the best presecription for maximizing calcium absorption in the diet? Anyone...?

Do you eat a lot of food with high oxalate content (most nuts, spinach, rhubarb and chocolate are some of the really big offenders.) Oxalic acid is an anti-nutrient that binds with the calcium in your food to form calcium oxalate. This keeps the calcium from being absorbed into your blood stream. Severe demineralization of bones is seen in people with low calcium intake and high oxalate intake. You are not one of the low calcium intake crowd, but you may be keeping yourself from absorbing a lot of the calcium you do eat if you eat a lot of oxalate.
Two good sources of oxalte information are:

It seems like you are overdosing. I hear from numerous sources that 600mg daily is sufficient as long as your vitamin D status is good. I am constantly getting below this, so I am not sure if I should worry. It's difficult to get enough calcium without dairy.

From what I read if you take sufficient magnesium (I use transdermal magnesium) once the cells are saturated with calcium, the extra calcium gets flushed out of the body.
