Are you one of the vast majority of endurance athletes that don't have enough Vitamin D?

In speaking with Dr. Kevin Sprouse, our Chief Medical Advisor, he's seen very few athletes that had sufficient levels of Vitamin D. "Having insufficient Vitamin D levels is so common amongst my patient population of elite athletes that I've come to expect it".

Vitamin D plays an important role in supporting bone health, maintaining cardiovascular function, and regulating immune function. When you take Vitamin D it increases your body's absorption of calcium and that's where the SwissRX Vitamin D formulation stands out from the rest.

Swiss RX Vitamin D3 with Vitamin K2

This pharmaceutical-grade, clinically-backed, doctor-recommended combo ensures you're getting the most out of your vitamin D supplementation, eliminating any possibility of over mineralization in the wrong parts of your body.

Here's how it works...

When you have optimal levels of vitamin D in your body, you're able to absorb all the important bone-strengthening, immune-boosting minerals such as calcium and magnesium.

BUT if you're low on Vitamin K, your body may choose to store these minerals in places that you don't want, such as your arteries instead of your bones.

The top researcher in the space, Dr. Leon Schurgers of the Netherlands, showed that taking Vitamin D WITH the right form of Vitamin K, ensures the minerals get pulled into the bone matrix, where you want the calcium to go, instead of getting stored up and calcified in 'danger zones' such as your arteries.

In a nutshell, take vitamin D for absorption and Vitamin K for the regulation of Calcium. Together, they make the perfect pair.

What makes SwissRX Vitamin D the best?

SwissRX takes a pharmaceutical grade Vitamin D3 and combines it with the patent form of Vitamin K2 that Dr. Schurgers used in his research called MenaQ7® PRO. It has been shown that the MenaQ7® PRO stays in your blood for 72 hours versus inferior forms of Vitamin K2 that only last 4 to 8 hours.

Do I need to supplement Vitamin D or just get out in the Sun?

I asked Dr. Sprouse for his answer to this question, this is what he had to say:

"Conceptually, I think of it as athletes having extremely high utilization rates. Vitamin D essentially functions as a hormone in the body and is integral to muscle function, recovery, hormone formation, immune function, and many other processes. Athletes stress these systems to a greater degree and more frequently than sedentary people. There is also the fact that athletes who are outside for long periods of time often wear sunscreen, as they should. So it’s multifactorial. In the end, though, I suspect it comes down to burning through stores faster than they can be replaced".


Take 3 to 5 Drops (each drop is 1,000 IU) on your tongue or mix with a beverage or shake each morning. It is tasteless and you can swallow it immediately. Easily regulate your dosage with drops, as each drop is 1,000 IU so you can follow your doctors recommendations on daily intake.
