I have news for you. dairy doesn't add calcium to your body, it depletes it!!!
the best way to get calcium is from mineral rich foods especially green veggies.
for bodybuilders we need even more than the average person so a lot of us take multi-vitamins. a great one is Medivin from mr supps, and a good one at NTBM is the ruthless brand of multi.
overcalcification is a huge problem. Calcium is the counterpart to magnesium and most people are calcium rich and magnesium poor which causes a whole slew of problems, arterial calcification being one of the most devistating. Dr Thomas Levy actually just came out with a book called Death by Calcium. Calcium os one of the few supplements you never see me recommend.
While admirable, its nearly impossible to get what we need from food alone. A combination of poor food sources combined with massive exposure to toxins means we burn through antioxidants at a rate that simply cant be provided by food alone.
