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.

Comfortable and Easy to Wear Daily
Size: 2 Little Kid, Color: Navy/Blue
My daughter has been wearing these navy/blue shoes since the weather has been less rainy and more sunny. They are great for outdoor play, especially on days when it's warm outside. The knit mesh upper keeps her feet from overheating, and the cushioned insole feels supportive without being stiff. At size 2, the fit is accurate and the width runs a bit roomy, which gave her some growing room without feeling loose. The slip-on design with elastic laces and pull tabs is a real plus. She can get them on and off without any help, which she loves. The shoes are light enough that she barely notices them during long active days. My one small complaint is that the sole feels more like firm foam than rubber, so they can be a little slippery on smooth indoor floors. For the price, these deliver solid everyday value. They look good, hold up well to regular use, and my daughter reaches for them first most mornings. Pros: - Breathable mesh keeps feet cool - Easy slip-on design with elastic laces and pull tabs - Lightweight and comfortable for all-day wear - Accurate sizing with a roomy width - Durable for the price Cons: - Sole can be slippery on hard smooth surfaces - Limited outsole grip compared to rubber-soled shoes

Great kids' shoe — easy on, comfy all day
Size: 3 Little Kid, Color: Pink/Lavender
My kid has been wearing these for a few weeks now and I'm genuinely impressed with how well they've held up. The knit mesh upper keeps feet cool and comfortable during long days at school and outdoor play, and the cushioned EVA midsole does a great job absorbing impact. What really won me over is the slip-on design with elasticated laces and dual pull tabs — my child can put them on and take them off completely independently, which is a huge win. The fit is snug but not tight, and they run a bit roomy in width, which is great for kids with wider feet or those who need a little growing room. At $32, the quality feels solid for the price. Lightweight, breathable, and easy to wear — these check all the boxes for an everyday kids' shoe.

Cute, Comfortable, Light-Weight Shoes, Perfect for School
Size: 11 Little Kid, Color: Pink/Lavender, Size: 11 Little Kid, Color: Pink/Lavender
These have turned out to be great everyday shoes for my 5 year old. She normally wears a size 10, but since that size wasn’t available, I ordered the 11 expecting her to grow into them. I was pleasantly surprised that they already fit her pretty well. There’s still a little extra room in the toe area, but the shoes fit securely around her ankles so they don’t feel loose or slip off while walking or playing. She says they’re very comfortable and loves how easy they are to slip on by herself. The lightweight design is nice for everyday wear, and they’ve held up well so far despite being worn almost daily. They've become her favorite shoes to wear! Also the pink/lavender color is really pretty in person. Overall, I’m very happy with them and would order again.

Great shoe well made
Size: 13 Little Kid, Color: Pink/Lavender, Size: 13 Little Kid, Color: Pink/Lavender
Really good shoes at a fair price. My daughter loves the pink and purple gradient colors. Really beautiful. Shoes have proven themselves very durable. She's been wearing these a few times a week for the last couple months and they still look new aside from some dirt stains. Fit perfectly. Very comfortable. This is always her first pick in the morning when she's getting dressed. Good breathability you can wear these in hot summer weather without sweaty feet. Versatile shoe looks good enough to wear out and about or exercise in.
