Regarding daily calcium intake alone: I keep it simple by tarketing 400 mg per each of my three meals.

Breakfast - Typically, 400 mg from Almomd milk on my cereal or oatmeal.

Lunch - Typlically, 400 mg from cheese and/or a glass of almond milk (partial, if one slice of cheese) .

Dinner - If no substantial calcium food source, I take my 400 mg Calciul Citrate caplet with dinner (along with 2,000 IU of Vit-D3 and 100 mcg of Vit-K2 to direct the calcium away from my arteries and to my bones).

Again, I mentally target 400 mg of calcium per meal (knowing it's OK to reach 600 mg during one meal, before your body elininates the rest). If ice cream treat/high cheese Italian meal for dinner/etc, I skip the 400 mg calcium caplet., as I will reach the 400 mg without it. Easy peas!!
