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 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:

"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 Swiss RX Story

We set out to find a supplement company we could trust for the world's top endurance athletes. A company that had the same obsession with quality and performance as our athletes do. After all, why spend millions of dollars optimizing the performance of a Tour de France champion only to give him a low-quality supplement with inferior or ineffective ingredients?

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. But Swiss RX takes it even another step further. Whenever possible, they use the exact ingredients used in medical studies but are often too expensive for supplement companies to use.  What we love about SwissRX is that our athletes can rest assured they are getting the identical ingredients that were proven to be effective in these studies.

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

 

The SwissRX Guarantee

We know SwissRX is expensive, but you get what you pay for- especially when it comes to supplements. Other brands may be cheaper, but so are the quality of their ingredients. If you're anything like me, you'd rather pay a premium and KNOW you're getting the highest quality and most effective product possible 

That said, you can try it RISK-Free.  We are 100% confident SwissRX is the best supplement in the world, which is why guarantee it. If for any reason at all you are not THRILLED with your results after using this product for three weeks, contact us within 60 days of your purchase and a no-hassle MONEY BACK refund in the form of Feed Credit.

Worth the investment
Size: 1 Panel, Size: 1 Panel
I had to order this in an emergency. To put it in brief words, I live in a two level studio unit. My bedroom TV fell backwards off the bureau accidentally and down the stairs to its demise. Putting this together was no problem, instructions were thorough and easy. It came with several bars that connected together smoothly and an Allen key for the brackets and screws for the feet. I did one less horizontal bar on top and bottom so it could fit, which was great because with all of them on it was too long. However I ran into the difficulty of the horizontal bars popping out of the brackets during the last stages, but eventually got it done. I was also looking for a specific type of divider where I could adjust the feet so I could tuck it in between the dresser and banister. Glad I made this purchase.

You Get What You Pay For! A Piece Of Junk!
Size: 1 Panel
Flimsy and a piece of junk. Don’t waste your money. Assembly is a pain because it is so flimsy. Divider is thin. You can see right through it. Very wobbly.

Instructions are useless
Size: 1 Panel
The instructions are poorly written and not very helpful. The divider itself is easy to assemble, and honestly, it would’ve been quicker if I had skipped the directions altogether. Once put together, though, it works as intended.

This was the best
Size: 1 Panel
This divider is great for creating a little privacy or separating a small area without taking up much space. The fabric is thick enough to block visual clutter, and the frame is lightweight but stable once it’s opened. It folds flat for storage, which is convenient if you only need it occasionally. Assembly was straightforward, and it was the perfect size. It’s a practical piece for apartments, studios, or home offices where you want a quick, temporary partition.

Good privacy screen
Size: 1 Panel, Size: 1 Panel
This is a good privacy screen that's easy to assemble and looks nice. Be a little careful moving it, as the corners can twist. It's sturdy once in place, and the thick material is completely opaque. If the folds bother you, you might want to iron it, but I'm happy with it as is.
