Everything about Calcium
Calcium: all articles — from dosage to timing, explained clearly.
Buying calcium: elemental mg, not mg of salt
Which number on the pack counts, how large the daily serving should be, what tablet size tells you — and how two calcium products can really be compared.
Too much calcium: where the upper limit sits
2,500 mg counts as the tolerable total intake, while the BfR suggests only 500 mg from supplements. Why both figures are right and what matters long term.
Vegan calcium: what actually gets absorbed
Kale, tofu, sesame, plant drinks: which plant calcium sources the body takes up — and why the oxalate in spinach blocks almost all of it.
Calcium and vitamin K2: why K2 gets mentioned
K2 is said to steer calcium into bone instead of arteries. What is authorised, what EFSA examined and rejected — and which pair actually belongs together.
Calcium and vitamin D: why they share a tablet
Vitamin D decides how much calcium the gut absorbs — which is why both sit in one tablet. When the combination makes sense and when one of the two is enough.
Calcium and magnesium: together or apart?
Whether calcium and magnesium can be taken together, how large the single portions should be and why the ratio is the wrong question.
Daily calcium needs: 800 mg label, 1,000 mg advised
The pack states 800 mg as a reference value, the DGE recommends 1,000 mg. What the daily requirement is, how much food covers and when a tablet helps.
Calcium in food: the portion beats the 100 g figure
Cheese, kale, mineral water, plant drink: how much calcium each food delivers per portion — and the two places in the chiller cabinet where the sum falls apart.
Calcium forms: carbonate, citrate, gluconate
Which calcium compound is worth it: elemental content, stomach acid and what the studies really show about absorption — and why serving size decides more than the salt.
Taking calcium: dose per serving and spacing
Why the size of a single dose matters more than the time of day, which gap to iron, zinc and medicines is real — and which one, by the measurements, is not.
