Have you ever wondered: “I take calcium supplements every day, so why does my doctor still say I’m deficient?”
In fact, taking a lot of calcium doesn’t necessarily mean your body gets enough — the key lies in how well your body absorbs it. If taken incorrectly, calcium can “go astray,” leading to constipation, kidney stones, and calcium buildup in blood vessels, which can gradually harm your health.
Let DDA Vietnam help you decode the calcium absorption process — so you can understand it right, take it right, and absorb every bit of this golden mineral!
1. Where does calcium go when you take it every day?
Each time you take calcium, only about 30–40% of it is actually absorbed into the bloodstream. The rest is eliminated through the digestive tract — especially if you’re using inorganic calcium (like carbonate or phosphate).
The reasons:
Inorganic forms are hard to dissolve and absorb, especially for those with low stomach acid (common in middle-aged and elderly people).
Calcium can get “stuck” in the intestines, unable to reach the blood and bones.
Meanwhile, organic calcium — such as the calcium extracted from eggshells by DDA Vietnam — is completely different:
Dissolves quickly in the intestinal environment.
Penetrates efficiently through the intestinal wall for direct absorption into the bloodstream.
Is 3–4 times more effective than regular inorganic calcium.
2. Common mistakes that make you “keep taking calcium but never get enough”
Taking calcium with coffee, tea, or carbonated drinks – caffeine and phosphate reduce calcium absorption.
Taking calcium together with iron or zinc – these minerals compete with each other during absorption.
Taking calcium late at night – when metabolism slows down, calcium tends to deposit and form kidney sediment.
The right way to take calcium:
Take it 30 minutes after breakfast or lunch.
Drink plenty of water and get 15–20 minutes of morning sunlight daily to help your body naturally produce Vitamin D.
