Elderly Coffee Drinkers Need More Calcium

If you’re over 60 and enjoy your daily cup—or two—of coffee, there’s something important to consider beyond taste. Many older adults drink coffee regularly, often without realising that caffeine, a key compound in coffee, can affect how the body handles essential minerals like calcium. This isn’t about quitting coffee, but understanding how your morning brew might be impacting your bone health—and what to do about it.

The short answer? Yes, coffee can increase calcium loss. Studies show that just two cups of coffee can cause the body to lose around 15 milligrams of calcium. To balance that, older coffee drinkers are advised to take in an extra 100 milligrams of calcium per day or drink at least one glass of milk to make up the difference.

How Much Caffeine Is in a Cup of Coffee?

Most coffee sold in markets today is instant coffee, which contains caffeine. On average, a single cup of coffee includes roughly 50 milligrams of caffeine. This caffeine stimulates the nervous system, helping drinkers feel more alert, reducing tiredness, sharpening mental focus, and even increasing appetite and aiding digestion.

Why Caffeine Can Affect Calcium in Older Adults

Caffeine doesn’t just wake you up—it also influences how your body absorbs and retains certain nutrients. In older adults, research has shown that caffeine intake is linked to increased urinary calcium excretion. One study involving 135 coffee drinkers found that 133 of them excreted twice as much calcium in their urine after consuming coffee compared to when they didn’t drink it.

How Much Calcium Do You Lose Per Cup?

According to the same study, drinking two cups of coffee results in the loss of approximately 15 milligrams of calcium through urine. While that might not sound like a lot, it can add up, especially for older individuals whose calcium intake is already lower or whose absorption is less efficient. Over time, this imbalance may contribute to reduced bone density if not addressed.

How to Compensate for Calcium Loss

To offset the calcium lost due to regular coffee consumption, researchers recommend that older adults increase their daily calcium intake by about 100 milligrams. This can be achieved by:

• Adding one cup of milk to your daily diet (a common source of about 300 mg of calcium)
• Taking a calcium supplement if advised by your doctor
• Eating more calcium-rich foods such as leafy greens, yogurt, cheese, tofu, and almonds

It’s a simple balancing act: enjoy your coffee, but ensure your diet supports your bone health at the same time.
