How much calcium do we really need?

I am reading a lot of conflicting evidence on the internet about Calcium intake. At the moment i am not getting a lot of calcium in my diet, so i was thinking of getting a supplement or eating more calcium rich foods.

But i came across these videos

What do you guys think? How much Calcium do we [B]really[/B] need?

Here is a good chart for calcium requirements for different age groups. I'm a still growing 18 year old so I strive for 1000-1,500mg per day.

Yea i'm 18 too thats why i was really thinking about upping my calcium intake, frustratingly the guys in the videos don't actually say how much calcium to actually take. They say we need less calcium and more magnesium and other minerals, but they don't actually say how much calcium is less.

Yes, I do believe calcium supplementation is harmful. You should focus instead on getting the complete set of synergistic micronutrients. K2, magnesium, D3, etc.

Yea i pretty much get everything as in potassium, k2, magnesium, d3 etc but i think i get very little calcium, the only thing i eat that has calcium is brocolli. Should i try and shoot for a certain number? about 500-600mg? at the moment i would say i am getting 100-200 if even.

ok will do, was just wandering if eating little to no calcium was problematic.

You could make sure you get everything you need by adding bone stock to your diet. I don't know how much of what we need, but I trust the bones I eat to know for me. ;) (I'm no longer growing, but I am in prime aoseoporosis country with the bones "of a woman half my age" according to my doctor, so I think it's working.

You need plenty of Vitamin D to make any use of calcium you ingest. Fortunately you can get both calcium and Vitamin D in canned fish, a nice convenient package. No need for supplements. You could also make a big spinach salad and go eat it in the sun.
