Does high dose vitamin C upset your stomach? 

If you want to boost your immunity, reduce inflammation, and support collagen formation but DON'T WANT the stomach upset that usually comes with the high concentration of vitamin C, then you want to consider using SwissRX's Buffered Vitamin C in your daily routine.

Here's why...

Vitamin C is crucial to immune system function, athletic recovery, and collagen formation. However, when taken at recommended therapeutic levels, vitamin C can cause stomach issues: pain, cramping, and diarrhea.

But it doesn't HAVE to be that way.

Which is why I'm excited to...

Introduce you to Swiss RX Buffered Vitamin C...

A premium high dose vitamin C balanced with calcium, magnesium, and potassium to reduce the potential of stomach upset, allowing you to get a clinically effective dosage of Vitamin C while minimizing GI upset issues.

This is the biggest issue pro athletes have with Vitamin C. They know they need to take it for all the reasons below, but to get enough (i.e. 2g to 3g every 4 to 6 hours) to be really effective can cause havoc on their GI tract and loose stools. 

SwissRX took on this challenge and it's Buffered Vitamin C eliminated most if not all GI issues with it's top athletes at dosages of 2g to 3g taken multiple times per day.

Why Do Athletes Need Vitamin C?

  • Immune Function & Antioxidant Support Vitamin C supplementation has been studied for more than six decades for its role in supporting the body during immune challenges. It's been shown to stimulate both the production and function of white blood cells, especially neutrophils, lymphocytes, and phagocytes.  It's especially important for athletes to increase their Vitamin C dosages to the clinically effective levels during times of high stress, large training volumes, travel, and certainly in the weeks proceeding and following major competitions.
  • Connective Tissue Health Vitamin C’s role in collagen formation makes it vital to maintaining skin, capillary, gum, joint and skeletal health. The antioxidant properties of vitamin C and its role in collagen synthesis make vitamin C vital to skin health. While SwissRX Collagen comes with Vitamin C in the formula, we see most athletes also taking SwissRX Buffered Vitamin C along with their Collagen.

How We Use It 

We recommend taking 2 to 4 capsules for general daily maintenance. But during times of high stress or when you feel you might be getting sick, we recommend you consider an increase to 6 to 8 capsules every 4 to 6 hours. 

To learn more about Vitamin C and dosages we recommend you check out Dr. Rhonda Patrick's post on all things Vitamin C.

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 same 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.

EXCELLENT CHOICE
Size: Standard (High Loft), Number of Items: 1
ABSOLUTELY AWESOME ! I TRIED A MEDIUM SOFT PILLOW FROM ANOTHER COMPANY FOR $35 LESS, BUT IT COULDN'T STAND UP TO MY NEEDS OR EXPECTATIONS. THIS STANDARD SIZE PILLOW THAT IS "FIRM" AS OPPOSED TO SOFT OR MEDIUM, IS FANTASTIC FOR MY HEAD AND NECK. IT IS KEEPING MY CERVICAL SPINE ALIGNED WHILE I SLEEP AND RELIEVING THE HEADACHES THAT I HAVE BEEN HAVING DUE TO MY DEGENERATIVE DISC DISEASE IN MY NECK. GREAT PILLOW AND WELL WORTH THE EXTRA MONEY. THANK YOU !

Goldilocks Pillow!! Queen Medium
Size: Queen (Mid Loft), Number of Items: 1, Size: Queen (Mid Loft), Number of Items: 1
Phenomenal pillow. I'm sure most people will have that trial by error with latex pillows, But I can assure you this pillow is the perfect balance of soft yet supportive, I'm 6" 1" 185 and I find it to be extremely comfortable, I purchased a queen medium, and upon opening it does have a vanilla/latex like smell(Not overly strong , but will dissipate in a few days if aired out, Ill mention this because im sure most people assume medium is hard, This isn't the case at all with this pillow, Its soft and supportive, I cant explain it any better than , It really is a Goldilocks pillow, Not to soft or firm but just right for my noggin. I'll also add my girlfriend liked it so much when she used it the second night, That I doubt I'll getting it back now,. All and all it's a great pillow and worth the money, Here's to many great night's with this Kiss Dream Queen Medium Latex Pillow!

Bouncy and cool
Size: Queen (Mid Loft), Number of Items: 1
I had been searching for a new pillow for weeks, but nothing was calling to me. So many go flat far too fast, and most cooling pillows are lumpy as can be. This one is perfect. Doesn't go flat, gives me comfortable support, and actually keeps cool longer than the average pillow

Needs to outgas for a day or two and then its great.
Size: Queen (Mid Loft), Number of Items: 1
Needs to outgas for a couple days, ideally outside on a clothes line. Having said that its the first pillow out of a half dozen Ive bought in the last 18 mos that I can sleep on. Sleeping much better and longer now. Latex foam is the only pillow for me. I swear I searched on here a year or so ago and could not find one.

Goldilocks pillow
Size: Queen (Mid Loft), Number of Items: 1
I tried 5 different latex pillows, 2 from this brand. Most had to much loft and were too firm. This brand has one called extra soft that was comfortable but a little too soft. BUT, I could tell the latex was better so I tried this one. It strikes the perfect balance of support and is not too firm. Compared to all the other brands I would call this one soft/medium as all others "medium" were pretty firm. This one is just right!
