SwissRX Vitamin D3/K2

Are you one of the vast majority of endurance athletes that doesn'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 patented 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:

"Short answer, I’m not exactly certain. 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".

How we use it

I use 4 drops per day in the AM (that is 4,000 IU). You can take it directly on your tongue or mixed with the beverage of your choice.  You can swallow it, you don't need to hold it in your mouth. 

The reason I like the drops is that it's easy to regulate your dosage.  Each drop is 1,000 IU so if your doctor recommends a lower dosage from 5,000 IU per day, it's easy for you to adjust. More is not better when it comes to Vitamin D.  You don't want to be deficient, but once you get to a sufficient level, most of the data suggest you get all the benefits and mega-dosing doesn't have any additional benefits.

The SwissRX Story

We set out to find a supplement company we could trust for the world's top endurance athletes: a company that has the same obsession with quality and performance as our athletes do. Our quest led us to SwissRX. SwissRX takes a "spare-no-expense" approach to procuring the highest quality Pharmaceutical Grade Ingredients. Only 3% of supplement companies go through the rigorous testing required for pharmaceutical grade labeling, SwissRX happens to be one of them. But they don't stop there; whenever possible, they use the exact ingredients used in medical studies, the same ones that many other companies point to in research, but don't use due to their price. We love SwissRX because our athletes can rest assured knowing that they are getting the identical ingredients that were proven to be effective in previous studies.

Simply stated, SwissRX products work better because they contain better ingredients.
