What no one told you about calcium and bones after 65

By Vitia

After age 65, taking care of our bones becomes more than a medical recommendation: it’s a vital necessity. For decades, we’ve been told that calcium is key to maintaining strong bones, but what actually happens to this mineral in old age is rarely discussed.

Many people continue to take calcium without knowing whether their body is absorbing it properly or whether they are combining it with the right nutrients. This article will reveal what few doctors explain: the hidden factors that determine true bone health after age 65.

After age 65, the body no longer processes calcium the same way it once did. This is where the problem begins. It’s not just about consuming more calcium, but also about understanding how it works with other elements in the body. These are the rarely mentioned aspects that could make the difference between maintaining good mobility or suffering unexpected fractures:

1. Calcium alone is not enough

Many older people take calcium supplements hoping to strengthen their bones, but they forget that without vitamin D , calcium cannot be absorbed effectively. Vitamin D is essential for transporting calcium to the bones, and with age, the skin becomes less efficient at producing it from the sun.

2. Vitamin K2, the great forgotten

Few people know that vitamin K2 is crucial for directing calcium to the bones and preventing it from accumulating in the arteries. Without this vitamin, calcium can end up in places where it shouldn’t be, increasing the risk of cardiovascular problems.

3. Exercise is key to fixing calcium

Taking supplements isn’t enough: physical activity, especially strength training or moderate endurance training , stimulates bone metabolism. Walking, lifting light weights, or practicing yoga can improve bone density and help calcium stay where it belongs.

4. Excess calcium can be harmful

Consuming more calcium than necessary, without the proper balance of other nutrients, can lead to kidney stones or soft tissue calcification. It’s important to consult a doctor before starting any supplementation.

5. Medications can interfere

Some common medications used by older adults, such as corticosteroids or stomach acid inhibitors, reduce the body’s ability to absorb calcium , which increases the risk of fractures.

Foods that help incorporate calcium naturally

While supplements may be necessary in certain cases, the best source of calcium remains food . Below, I share the foods richest in calcium and how to easily incorporate them into your daily diet:

Dairy

  • Milk, yogurt, and cheese are classic sources of calcium. It’s best to choose low-fat versions if you have cardiovascular problems.
  • Tip: Add plain yogurt to your breakfasts or as a base for healthy dressings.

Fish with soft bones

  • Canned sardines and anchovies are rich in calcium because they are eaten with bones.
  • Tip: Sardine toast is a quick and nutritious dinner.

Green leafy vegetables

  • Swiss chard, spinach, kale and broccoli provide plant-based calcium.
  • Tip: Sauté them with olive oil and garlic for a delicious side dish.

Legumes and nuts

  • Beans, lentils, chickpeas , almonds and sesame seeds contain calcium and other beneficial minerals.
  • Tip: Use sesame paste (tahini) to make hummus, or add flaked almonds to salads.

Fortified foods

  • Many products such as vegetable milk (soy, almond), cereals or orange juice are enriched with calcium.
  • Tip: Read labels and choose those that also include vitamin D.

Practical tips to strengthen bones

  1. Get at least 15 minutes of sun exposure per day (on your arms or legs, without sunscreen) to help your body produce vitamin D.
  2. I reduced my salt and caffeine intake , as they increase the elimination of calcium through urine.
  3. Avoid alcohol and tobacco , both of which affect bone quality and hinder calcium absorption.
  4. Don’t forget to get moving : Daily walks, gentle strength training, or stair climbing help keep bones active and strong.
  5. Consult a healthcare professional before taking supplements. Not everyone needs the same dosage, and taking too much can be dangerous.

Remember: calcium is only one part of the puzzle. Your body needs several elements working together to maintain strong bones after age 65. Adopting these habits and taking care of your diet can make a big difference in your well-being and independence.
