Should Older Adults Drink Coffee? Yes, But Watch Your Calcium

If you're over 60 and enjoy your daily cup of coffee, you’re not alone. But like many older adults, you might wonder: Is coffee safe for me? Especially when it comes to long-term health, such as bone strength and nutrient balance. Most coffee consumed today is instant or brewed, and even a regular cup contains enough caffeine to affect how your body handles key minerals like calcium.

Yes, older adults can drink coffee — but should be mindful of calcium loss. A single cup of coffee (with ~50mg caffeine) can cause the body to lose some calcium, and drinking two cups may lead to losing around 15mg of calcium. Experts recommend adding 100mg of calcium daily or drinking one glass of milk to offset this.

How Much Caffeine Is in a Typical Cup of Coffee?

Most of the coffee sold in markets today is instant coffee, which contains caffeine. On average, a single cup includes roughly 50 milligrams of caffeine. This caffeine is what gives coffee its well-known boost: it helps wake you up, reduces sleepiness, sharpens mental focus, may increase appetite, and aids digestion.

Why Could Coffee Be a Concern for Older Adults?

While the caffeine in coffee offers short-term benefits, studies have flagged potential downsides — especially concerning bone health in older populations. Caffeine affects how the body absorbs and retains certain minerals, notably calcium.

What Does Research Say About Coffee and Calcium Loss?

Researchers surveyed 135 regular coffee drinkers and found that 133 of them excreted significantly more calcium in their urine after drinking coffee — roughly double the amount compared to when they didn’t drink coffee. Further measurements indicated that drinking just two cups of coffee could lead to a loss of approximately 15 milligrams of calcium.

Based on these findings, experts advise that adults who drink coffee regularly should compensate for this loss. The recommended approach is to add about 100 milligrams of calcium to your daily intake. Alternatively, drinking one cup of milk per day can help replenish the lost calcium. Milk is a natural source of calcium and also provides other nutrients supportive of bone health.

How to Maintain Healthy Calcium Levels While Drinking Coffee

If you’re an older adult who enjoys coffee, here’s how you can continue to do so without compromising your bone health:

• Be aware of calcium loss: Recognize that caffeine in coffee can increase urinary calcium excretion.
• Aim for balance: For every two cups of coffee, consider adding 100mg of calcium to your diet.
• Include milk or dairy: Drinking one cup of milk daily helps replace the lost calcium and supports overall nutrition.
• Eat calcium-rich foods: Make sure your regular meals include foods high in calcium, such as leafy greens, yogurt, cheese, almonds, tofu, and fortified plant milks.

Frequently Asked Questions

Can older adults drink coffee safely?

Yes, older adults can drink coffee safely in moderation. The key concern is calcium loss due to caffeine. A typical cup of coffee contains around 50mg of caffeine, which can slightly increase calcium excretion. It’s not dangerous on its own, but over time it may contribute to lower calcium levels if not balanced with diet.

How much calcium is lost from drinking coffee?

Drinking two cups of coffee may result in the loss of approximately 15 milligrams of calcium through increased urinary excretion. One study of 135 coffee drinkers found that most excreted about twice as much calcium in their urine after consuming coffee.

How can I replace the calcium lost from coffee?

You can replace lost calcium by adding around 100 milligrams of calcium to your daily diet or by drinking one cup of milk. Milk provides roughly the amount needed to offset the calcium loss from two cups of coffee and also offers other nutrients important for bone health.

What foods are high in calcium besides milk?

Calcium-rich foods include leafy green vegetables (like kale and spinach), yogurt, cheese, almonds, tofu made with calcium sulfate, canned sardines with bones, and fortified plant-based milks such as almond or soy milk. Including these in your diet helps maintain strong calcium levels.

Is decaf coffee better for calcium retention?

Decaf coffee contains little to no caffeine, so it is less likely to affect calcium excretion compared to regular caffeinated coffee. However, the article does not specifically study decaf, so the same general advice on calcium-rich foods applies if you drink decaf regularly.
