As we grow older, our bones start to weaken, and our risk of developing conditions such as osteoporosis increases. To maintain strong bones and general health, we need to incorporate nutrients that maintain bone health into our diets.1 Calcium, magnesium, and vitamin D are crucial for maintaining healthy bones and bone quality.1 Here, we explore the benefits of these essential nutrients and why they should be taken together to reap the most benefits. 

Bone health is something we tend to neglect until it’s too late. We take our bones for granted, without realising that they play an essential role in our daily lives. Bones provide the framework for our body and protect our vital organs.2 They also store calcium and other minerals that support our overall health. But as we age, our bones start to lose mass and density, making them more prone to fractures and breaks.2 That’s why it’s crucial to take care of our bone health, and one way to do that is by ensuring you get enough Calcium, Magnesium and Vitamin D.1  

Benefits of Calcium, Magnesium & Vitamin D 

Calcium is the most abundant mineral in the body and is vital for several bodily functions, particularly bone health.2 Magnesium is also essential for healthy bones, as well as for muscle function and a healthy heart.3 Vitamin D plays a crucial role in maintaining healthy bones and helps the body absorb calcium and magnesium.4 Together, these three essential nutrients offer a range of benefits, including: 

1. Supports bone mass and density: Calcium is necessary for building and maintaining healthy bones, and magnesium and vitamin D support this process by helping to absorb and regulate calcium in the body.1 

2. Supports bone health and strength: As we age, bones become weaker and more susceptible to breaks.2 Calcium, magnesium and vitamin D work together to maintain the strength and quality of our bones, reducing the risk of fractures and osteoporosis.1 

3. Supports calcium absorption: Without sufficient vitamin D, the body cannot absorb adequate calcium from the diet.4 Together, calcium, magnesium and vitamin D ensure that calcium is absorbed efficiently and used to maintain healthy bones. 

4. Supports magnesium levels in the body: Magnesium deficiencies are common, and a lack of magnesium can lead to weak bones. Magnesium is a cofactor in almost 80% of enzymatic reactions within the body. It’s essential for the conversion of vitamin D into its active form, which can be used by the body. Magnesium is also used by the thyroid to stimulate the production of a molecule called calcitonin — a bone preserving hormone which helps to regulate bone breakdown.3 

When to take calcium, magnesium, and vitamin D 

Calcium, Magnesium and Vitamin D supplements are best taken together, as they work synergistically to support our bone health.1 If you are looking to take a calcium, magnesium and vitamin D supplement, the timing of when to take it may help your body to get the most out of these nutrients. Calcium should ideally be taken with meals, as it is absorbed best in the presence of food.5 Magnesium supplements can be taken at any time of the day, and similarly to calcium, vitamin D is also best taken with food, particularly a meal containing fats as this vitamin is fat soluble.6  

Is a calcium, magnesium, and vitamin D supplement right for you? 

If you’re not getting the recommended daily intake of these essential nutrients from your diet, you may wish to consider taking a supplement. Eating a balanced diet rich in calcium, magnesium and vitamin D is the best way to ensure optimal bone health, but it’s not always easy to get the right amount of these nutrients from food alone. A supplement that contains all three essential nutrients is an excellent way to ensure that you are supporting your bone health and overall wellbeing.
