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. 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. There also is no need to return the product to us, just send us a picture.

BEST PILLOWS EVER!!!
Color: White-cooling Basic, Size: Queen(Pack of 2)
I am very picky with my pillows because I have a bad neck and I can never seem to find a good pillow. But I tried this pillow because it had everything I was looking for and the price was great! You get two of them and they are absolutely awesome.! normally I would need to lay on two pillows to try and get comfortable but with these pillows I just lay on one and I wake up with no neck pain. They really have a nice cooling effect. They actually puff up immediately after opening them. All you have to do is just shake them up and the pillow just puffs straight up.. It comes with extra cushioning if you want it to make it firmer and if you don’t want it as firm as it is, you can actually take some out. It really is such a beautiful pillow. It’s perfect in every way to me being such a picky pillow person. You just lay your head down on it and it forms around your neck and your head and when you get up, it goes right back to its normal form. It doesn’t get flat and I love it. I completely recommend this to anyone who is a person who has a hard time finding a really good pillow.

Top of the line, best pillows Ive ever had
Color: White-cooling Basic, Size: Queen(Pack of 2)
These pillows are top of the line! I bought them in 2024 and they are still fluffy. When they lose a little fluff, you just punch em around a little bit and voila, like new again. They have kept their shape cery well and do great for cooling. I haven't had to add more filling yet either. I just laid my head on one and thought, I need to do a review cause everytime i lay on these pillows its like clouds. My head is heavy and this is relief :-D

Weird smell
Color: White-cooling Basic, Size: Queen(Pack of 2)
The pillows are great for someone looking for something cool and comfortable. We loved them so much that we bought a second pair. However, we were seriously disappointed with the odor of our last purchase. They give off a strong and indescribable chemical/burning plastic smell so nauseating that it’s difficult to sleep with. We’re hoping this issue will resolve with a couple more washes of the pillow cases, but am worried the source is the stuffing itself.

helped treat my sore neck
Color: White-cooling Basic, Size: Camping Pillow(Pack of 1)
This pillow — after dialing in the right amount of shredded foam — has greatly helped my sore neck. Initially, I had to remove some foam. Then I gradually added foam until it reached optimum comfort and support. It is also CPAP-friendly — especially when I position my head near the pillow's edge. (I am a left-side sleeper.) I like the travel size because I use a bulky hugging pillow to ease stress on my shoulder and elbow. That makes my side of the bed feel cramped if using a larger head pillow. A smaller pillow is easy to flip end-to-end in the middle of the night. I have spent lots of money on pillows over the years, but this is the best I've ever had for relieving [1] neck pain and [2] CPAP mask seal problems. Very comfortable, supportive, and affordable. I did not notice any unpleasant smell — and I am usually sensitive to that kind of thing. Would highly recommend.

Love them!
Color: White-cooling Basic, Size: Queen(Pack of 2)
Love them! After 10 years with our MyPillows, they finally lost their fluff. The reviews I read of the MyPillows of today were not good; they didn’t have as much filling as they used to. These pillows remind me of how fluffy our new MyPillows were 10 years ago!! You sink right into them and can mush them however and they stay. These are way cheaper than the Coop and it’s the same concept; add or remove the filling as needed. The cooling side is a huge plus too! You won’t be disappointed with these pillows!
