This is our favorite and one of the most simple performance-boosting supplements on the market.  It is phenomenal at increasing oxygen uptake and buffering lactic acid. What you feel is that during hard efforts your legs will simply hurt less, enabling you to push harder than you normally could in training and racing.

Beets have been known to help boost endurance performance for a while, but Sur AltRed is the first beet supplement on the market that contains only betalains extract, the nutrient that produces the red pigment in beets. AltRed uses a proprietary extraction method to remove nitrates and sugars, creating a betalains concentrate with increased bioavailability. You cannot get this from whole beets, beet juice or beet powders.

So what exactly do these betalains do? The AltRed Betalains in these tiny capsules improve oxygen delivery to your muscles and allow you to go further, faster, and longer in training and competition. AltRed's clinically proven athletic performance and recovery benefits are backed by science, 8+ years of field testing, and world champion endurance athletes. These studies have shown that Sur AltRed can help athletes:

  • Increase power output
  • Cover more distance for the same effort
  • Increase cycling and running efficiency
  • Reduce markers of muscle damage
  • Recover better

AltRed is also safe for sport. It is tested by both NSF Certified for Sport® and Informed-Choice Trusted by Sport. Can you say win-win? We've been testing this in-house for some time now and the results are outstanding. This is now a staple in our supplement closet and the results are in. It works...and works well!

Does it work?

Sur has conducted three gold-standard clinical studies that prove positive effects for endurance athletes taking AltRed. Gold standard studies are double-blind, crossover, placebo-controlled, and randomized. Additional studies are in the works and will be added as they are published. 

Highlights from studies:

  • 3.5% more watts
  • 3% faster times  
  • 15% reduction in perceived exertion 
  • 2.5% more distance   
  • 5.4% increased exercise efficiency    
  • 9% reduction in exercise-induced muscle damage    
  • 14% less lactate acid production

The runners also saw an average 14% reduction in lactate acid levels and a 15% reduction in perceived exertion. Read full study 

Betalain-Rich Concentrate Supplementation Improves Exercise Performance and Recovery in Competitive Triathletes

Another study at the University of California, Davis conducted on triathletes showed that they performed an average of 3% faster in a 5K recovery time trial performed 24 hours after completing a 10K time trial when they used AltRed. The triathletes also experienced an average 9% reduction in a key muscle damage indicator known as creatine kinase. Read full study

Summer wedding kids suit
Color: Navy, Size: 10 Years, Color: Navy, Size: 10 Years
Bought this suit for my son in the 10 youth size and honestly was pleasantly surprised by the quality for the price. The navy color looks sharp and dressy without being too stiff or uncomfortable. The material has a little stretch, which helped it fit nicely and made it comfortable for him to move around in. The adjustable waist was a huge plus, especially for growing kids. It fit true to size overall, though the blazer sleeves were slightly long on my son. The pants had a nice slim look without being too tight. We paired it with white sneakers for a more modern look and it came out adorable. This would be perfect for weddings, graduations, concerts, communion, school events, or family photos. Overall, very happy with the purchase and would definitely buy again.

Very Modern Handsome Suit
Color: Grey, Size: 7 Years, Color: Grey, Size: 7 Years
This is an incredibly sharp looking suit for the little guy. Great price and features, too. I made a mistake in sizing up instead of down and first one was too sloppy on him and would need alterations. He is thin and very thin in the waist. There is a lot of adjustment with buttons in waistband and coat hides the bunching. This shirt and coat will easily take a fuller body than slim I believe. He loves posing in it and feels very classy. Best purchase for a formal suit that will last longer than most kids clothes size wise. Felt bad about returning but careful folding and packing got it good as new.

Sharp Looking Kids Suit With One Missing Piece
Color: Navy, Size: 7 Years, Color: Navy, Size: 7 Years
I ordered this suit for my 6yo son in a size 7 so he would have a little room to grow and get more wear out of it, and sizing is perfect. He did not need it for any specific occasion, he just wanted a suit because apparently kindergarteners sometimes wake up and decide they are businessmen now. Let me start with the positives because there are a lot of them. This is a very well made suit. The jacket, pants, and dress shirt are all surprisingly nice quality. The fabric does not feel cheap or flimsy at all. The jacket has good structure, the buttons are well attached, the seams are clean, and all the little details like the collar and pockets look great. It honestly looks like a proper little formal suit. The pants are nicely made as well and pair perfectly with the jacket. The white dress shirt underneath is also good quality and completes the whole look. Overall, it is a really sharp outfit and would absolutely work for special occasions like weddings, recitals, formal events, church, or family photos. Now for the reason I am deducting one star. The listing specifically shows and mentions that this set includes a bow tie. That was actually the main reason I chose this particular suit over others. Some options only had a standard tie or no tie at all, but my son specifically wanted a bow tie. Unfortunately, the bow tie was not included with mine. That was definitely disappointing because it was one of the main selling points for me when choosing this set. Now I have to go find a separate bow tie that matches, which I was hoping to avoid. That said, I do want to be clear that this issue does not take away from the actual quality of the suit itself. The suit is genuinely very well made and looks fantastic on him. If your child needs a suit for a wedding, formal event, recital, or something similar, this would absolutely work. My son mostly just wanted a suit because he thinks it is cool, so now he has one and can show up to school looking like the smallest CEO in kindergarten. Overall, this is a very nice quality suit set. I just wish the bow tie that was advertised had actually been included.
