One Major Effect Vitamin D Has On Your Bones, Says Science

Vitamin D and calcium make the perfect pairing for optimal bone health.

Fall is here, winter is approaching, and we are saying goodbye to the summer sun. As the days get shorter and we spend less time getting natural sunlight, it's important now more than ever to focus on getting adequate levels of vitamin D.

Vitamin D has a long list of health benefits that include boosting your immune system, reducing depression symptoms, and even helping to diversify your gut microbiota.

It has also been known to greatly improve bone health in a number of ways, and one of the most crucial ways vitamin D impacts your bones is by helping your body absorb more calcium.

Vitamin D and calcium absorption

According to Nutrients, your peak bone health occurs in your 30s, while you start to slowly lose bone mass in your 40s. Although things like genetics, lifestyle, and diet affect your bone health as you age, your levels of vitamin D play a huge role as well.

This is because your body needs vitamin D to absorb calcium, another crucial nutrient for bone health, and according to a report from Therapeutics and Clinical Risk Management, vitamin D deficiency decreases bone strength overtime for this very reason.

Calcium and vitamin D are necessary for bone health because of where calcium is stored in your body. The majority of your body's calcium is stored in your bones and teeth, with a smaller fraction found in your plasma. Although the levels of plasma calcium are small, they actually control the rest of the calcium in your body.

If you don't have adequate levels of calcium in your plasma, your bones will go through a process where they release their own calcium to help restore everything back to normal.

The unfortunate thing about this process is that it weakens your bones, which is why it's important to get enough calcium on a daily basis, and equally important to get enough vitamin D to help your body absorb the calcium!

Other ways vitamin D can help your bones


The report from Nutrients also discusses the relationship between vitamin D and one of the biggest risk factors for bone fracture: falling at an old age. This report states that vitamin D can help strengthen muscles and help reduce the risk of falling.

The report also highlights the possibility that vitamin D can help lower inflammation, which in turn can help lower the risk of osteoporosis, although more research still needs to be done.
