Which Is Better for Bone Health?

Research suggests that one is not better than the other when it comes to bone health. They are both essential for strong, healthy bones:

• Calcium builds and strengthens bones by supporting bone structure.
• Vitamin D helps your body absorb calcium and supports bone function.
• Vitamin D intake ultimately helps ensure calcium works how it should.
• You need a balance of both calcium and vitamin D to optimize bone health. Using both together may offer some reduction in fracture risk in older adults.

Both nutrients work together to maintain strong and healthy bones throughout life. Too little of either nutrient can lead to weak, brittle bones, and too much can cause unwanted side effects. Further research is needed to better understand the individual roles and benefits of these compounds for bone health.

How Does Calcium Make Strong Bones?

Calcium is a mineral that provides essential support for bone structure and strength. Calcium deficiencies lead to weak bones and can even lead to osteoporosis (brittle and fragile bones).

If you don’t get enough calcium from your diet, your body pulls it from your bones to keep blood calcium levels stable for other functions. Over time, this process can weaken your bones and increase your risk of fractures.

Food sources of calcium include:

• Dairy products
• Fortified milks, cereals, and orange juice
• Leafy green vegetables such as greens, kale, and spinach
• Tofu
• Canned fish, like sardines and salmon

Taking calcium without enough vitamin D can lead to poor absorption, meaning your body may not be able to utilize it properly.

Who Do You Need Vitamin D for Strong Bones?

Vitamin D is a fat-soluble vitamin. It supports bone health by supporting the body’s absorption of calcium. If you don’t consume enough vitamin D, your body may not absorb enough calcium.

Sunlight exposure is the most optimal way to increase vitamin D.

Food sources of vitamin D include:

• Fatty fish like salmon, mackerel, trout, and tuna
• Egg yolks
• Fortified foods such as milk, orange juice, and cereals

You can also take vitamin D supplements if you’re unable to get enough otherwise.

Taking vitamin D without adequate calcium won’t help if you don’t consume enough calcium.

How Much Do I Need?

Getting the appropriate amount of calcium and vitamin D is essential.

The average daily recommended amount of vitamin D for most children and adults under 70 years of age is 600 international units (IU) of vitamin D daily. Infants and older adults may require slightly less or more.

The daily recommended amount of calcium ranges from 1,000 to 1,300 mg daily for individuals up to 50 years of age.

While these are the recommended amounts, levels may need to be monitored, and individual needs may vary. Before starting a supplement, consult with your healthcare provider to determine the optimal dosage.

What Happens If I Get Too Much Vitamin D or Calcium?

Too much vitamin D can result in the body absorbing too much calcium. In general, high blood calcium can lead to issues like:

• Kidney problems, like kidney stones
• Bone pain or bone fragility
• Digestive symptoms, like nausea, vomiting, or constipation

Most people can meet their calcium and vitamin D needs safely through a balanced diet and adequate sun exposure. Supplements can help if needed.

It’s best to have your levels checked by your healthcare provider, who can recommend the correct amounts based on your specific needs.
