2. Excessive Caffeine
The concern: Caffeine mildly increases calcium excretion through urine—about 4–6 mg lost per 150 mg of caffeine (roughly one cup of coffee).
The threshold: Risk emerges with more than 400 mg daily (≈4 cups coffee) without adequate calcium intake.
The reassurance: Moderate coffee (1–3 cups) poses no threat when paired with calcium-rich foods. In fact, adding milk transforms your cup into bone support.
Your move: Limit to 2–3 cups daily. Stir in fortified plant milk or enjoy a yogurt alongside your brew.
