What we think

Is your vitamin D missing something? 

As an athlete (especially after going through 2020) you probably know that taking vitamin D is absolutely essential for immune health -- especially in winter months, cloudy climates as well as for athletes who train hard in the summer and use sunscreen.

But not all vitamin D supplements are created equal and it’s important to look for a vitamin D supplement that includes a couple of other key nutrients (like Thorne). That’s because our bodies have a difficult time absorbing vitamin D property without adequate levels of another important vitamin. 

Thorne has solved this problem for us by combining Vitamin D and Vitamin K2 so that we absorb these vitamins properly without risking unwanted calcium deposits in dangerous places, like our arteries. 

Whether you’re a marathoner pounding the pavement or a triathlete swimming 5-6 days a week, these vitamins are crucial to keeping your bones in good condition so you can continue to do the things you love long into old age.

Why is Vitamin D so important? Vitamin D is an amazing “Master Vitamin”, regulating your immune function and neuromuscular system. It’s basically the Top Dog of vitamins as it’s difficult for your body to absorb other nutrients without it.

If you are low or insufficient, you can get sick more easily, suffer from low energy, weak muscles, bone pain and fractures, depression, slow wound healing, hair loss, muscle pain, weight gain, and other serious complications. In other words, it ain’t pretty. 

Vitamin K2 also supports cardiac function and circulation, regulates cell growth, and lasts in your system for much longer than Vitamin K1. In addition to helping your bones grow and stay strong, Vitamin D maintains mineral density and helps prevents the risk of injury (fracture) in case you do happen to crash in your next race.
