I need more calcium

I looked it up because low carb and low calorie options are hard to find if no diary...

•Canned fish with bones, like salmon and sardines, 3 to 4 ounces
•Hard cheese, like Swiss and cheddar cheese, 1 1/2 ounces
•Dark leafy greens, like spinach, kale and turnip greens, 1 1/2 cups cooked
•Calcium-fortified, unsweetened soy drinks (check labels, as calcium varies by brand)
•Broccoli, 2 ¼ cups cooked
and taking a supplement to make up the difference is also an option

enriched milks like soy/rice/almond have a good amount of calcium per serving. i eat lots of broccoli too. tofu/soy has calcium, and you can pair it with dark greens like spinach or mustard greens or bok choy. i also eat fortified oats & cereal to get both calcium & iron in my diet, but those aren't exactly low carb so eh.. then again i don't care about carbs
