    Supplementation with calcium is generally ineffective and sometimes dangerous. This is especially so if you are supplementing D3. The issues with calcium are more often caused by errant metabolism than by insufficiency. If you are getting enough D3, K2, Zn and Mg you should have no concern about calcium, less chance of CVD, better teeth and stronger bones
    Four years Primal with influences from Jaminet & Shanahan and a focus on being anti-inflammatory. Using Primal to treat CVD and prevent stents from blocking free of drugs.

    Eat creatures nose-to-tail (animal, fowl, fish, crustacea, molluscs), a large variety of vegetables (raw, cooked and fermented, including safe starches), dairy (cheese & yoghurt), occasional fruit, cocoa, turmeric & red wine

    I agree, and its not just how much calcium you are getting but how the calcium is interacting with other minerals, how your body is using the calcium and so on. Usually a big supplementation of one mineral will throw off another. Its best to eat the food and let your body sort it out.

    If you are getting close to 0 dietary calcium though and cant or dont want to add in the suggested foods or just good ol dairy then egg shell calcium is highly available and dirt cheap. Just save your egg shells, boil them and then powder them with a pestle and mortar.

    I thought that humans became shorter post agriculture? Taller before grains etc entered the human diet.

    I'm sure it's been mentioned already, but the current RDA for calcium is based on absorption rates which would not have been applicable to paleo folks (i.e. they didn't consume a lot of foods that hinder absorption). Also, depending on geographic location, they'd have gotten a fair amount of calcium and magnesium drinking naturally-occurring hard water from streams and rivers. In some areas that alone amounts to several hundred mg per liter.

    Vitamin D, Vitamin D, Vitamin D, Vitamin D, Vitamin D, Vitamin D...

    So many people are low in it. It's ESSENTIAL for calcium utilization. All of this talk about needing more calcium in the media... hooey. Get more vitamin D. Vitamin D also increases calcium absorption.

    In conclusion: VITAMIN D!!!

    P.S.

    - Vitamin K: improve your gut flora so your body makes more of it.
    - Magnesium: Many people don't get enough.

    I'm no expert, but I supplement with up to 10,000 IU depending on my sun exposure. Your body can make that much in less than an hour of being in the sun.

    The 1,000 IU guideline is the base amount needed to prevent disease (rickets I think).

    I take 10,000 IU as a Euroasian living in Scotland, where there is no sun! I think thats a high dose as you need to go unless you have some sort of medicinal condition.
