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.

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.

Apple Pencil Pro… definitely an upgrade from the original Pencil and Pencil 2!
Purchased as an open‑box, like‑new item, and it arrived exactly as described. The box was opened but taped closed and the wrapper was still on the pencil. It didn’t have any charge out of the box, but as soon as I snapped it onto the side of my iPad, it synced instantly and worked right away. I charged it fully that first night and have been using it normally ever since. I’m using it with my 13” iPad Air M2, and it’s great. The double‑tap on the barrel to bring up the menu is super convenient, and everything works flawlessly. Zero issues so far. For basically half the price of a brand‑new one, this feels like an excellent buy and absolutely worth what I paid. Apple hardware is built well, the white looks nice and clean… I have no worries about longevity at all. Excellent product from Apple as usual.

Super easy to set up and start drawing
I was honestly shocked at how easy it was to connect it to my iPad. Opened the box and was expecting to see more inside of it, decided to see what happens when I put it up to my iPad and it connected instantly. Works great with my iPad m2 with touch sensitivity and spiral twist stuff in procreate. Really happy to not have to plug it in to charge. I’m planning to use this daily, so I needed to make sure it would actually feel good to hold in my hand and oh baby let me tell you, it does. It’s really smooth drawing wise, using it is intuitive. Fits on the iPad snug. I’d say give it a shot

It works, but there’s some improvement needed.
The Apple Pencil Pro is easy to write with, not heavy like the other reviews made it seem, very nice and simple design, great battery life, great pressure sensitivity, and the squeeze feature and wireless charging is a nice touch. Theres one issue though, I’m an artist and student and I do a lot of work on my iPad. The pencil (or my iPad) glitches and randomly and switches me over to the eraser tool in the middle of me writing/drawing even when I turned the squeeze feature off.

Wonderful product!
I got the Apple Pencil (USB-C) a few months ago and I’ve honestly been so impressed with it. It pairs instantly with my iPad and starts working right away — no complicated setup at all. The USB-C charging is super convenient, especially since I already use the same charger for other devices. The writing experience feels incredibly smooth and natural. It’s very responsive with no noticeable lag, which makes taking notes, highlighting, and drawing feel effortless. I also love how precise it is — it makes writing neatly and editing small details really easy. It’s lightweight but still feels high-quality and durable. For note-taking, journaling, planning, or casual drawing, it does exactly what I need without the higher price tag of the Pro version. Overall, I think it’s a great value and a perfect choice if you want reliable performance without paying extra for features you may not need.
