If you’re looking for ways to strengthen your joints and tendons, you may have heard that vitamin D3 supplementation can help. Vitamin D3 is a vital nutrient that helps the body absorb calcium from the food we eat, which is important for a healthy skeleton. But there is much more to learn about how it benefits our joints and tendons. Let's take a look at five research findings on this topic. 

• Improved Joint Function
  A study published in The American Journal of Clinical Nutrition found that taking vitamin D3 supplements improved joint function significantly more than placebo pills. This improvement was seen in both men and women over the age of 60 who took vitamin D3 supplements over the course of one year.

• Better Tendon Strength 
  A study published in The Journal of Strength & Conditioning Research found that taking vitamin D3 supplements improved tendon strength by an average of 11% compared to placebo pills. This improvement was seen in athletes who took these supplements over the course of six weeks. 

• Reduced Risk of Injury 
  A study published in Archives of Physical Medicine and Rehabilitation looked at how supplementing with vitamin D3 affected athletes’ risk for injury. It found that those athletes who took a daily supplement had a significantly reduced risk for injury compared to those who did not take any supplement.

• Improved Bone Density 
  A study conducted by researchers from Harvard Medical School found that supplementing with vitamin D3 improved bone density significantly more than placebo pills. This improvement was seen after only three months.

• Reduced Inflammation
  A study conducted by researchers from Rutgers University found that taking a daily dose of vitamin D reduced inflammation significantly better than placebo pills. 

Vitamin D has long been known as an important nutrient for maintaining healthy bones but recent research has also shown its potential benefits when it comes to strengthening joints and tendons. These five research findings are just a few examples of how supplementing your diet with this essential nutrient could improve your overall health and wellbeing. If you're looking to increase joint mobility or reduce your risk for injury, then incorporating Vitamin D into your daily routine may be beneficial!
