By now, you’ve all heard about the benefits of the Ketogenic diet. Once used as a cure for childhood epilepsy, now being sought-after from endurance athletes worldwide. KetoneAid is a legal performance-enhancing sport and brain drink that quickly elevates ketone levels and provides the benefits of ketosis without all of the hardship. 

Until recently, exogenous ketones were a multi-thousand dollar investment. While not cheap, KetoneAid is part of the latest line of products specifically developed to enhance performance by providing a dual fueling system. Also known as glycogen sparing, exogenous ketones offer endurance athletes 60-90min of ketone-fueled energy, saving your precious glycogen reserves for when you need them the most.  How does it taste?  The flavor is named Very Scary Cherry. 

While it tastes better than earlier renditions of the product, it still isn’t up to the standards of something that you would purchase from your local juice bar. Most athletes are fine with it knowing that the longterm performance gains outweigh the short term taste discomfort.  Here are some of the performance benefits of using KetoneAid Ketones:

  • Increased endurance performance: by sparing muscle glycogen stores, lowering blood lactate levels, and increasing efficiency of muscles
  • Improved muscle recovery: increased rate of glycogen resynthesis (replenishing energy stores) and protein synthesis (rebuilding muscles), decreased muscle breakdown
  • Enhanced cognitive ability: ketones can cross the blood-brain-barrier to provide an efficient source of fuel for neurons, allowing you to sustain peak cognitive performance for longer
  • Support fasting and dietary goals: can allow you to stay in ketosis while consuming carbs 
How We Use It:

We typically like to consume 45min prior to event and supplement every 60-90min based on total duration. This product can and should be used with additional supplements/gels during your training and racing. During the off-season, we love to use on recovery days as a means of caloric restriction.

Not cooling
Size: Sapphire Queen
We have waited to give a review. These 2 pillows we purchased based off the good reviews and that it states has cooling effect. Well a good point it has is the blend of stuffing. Also the ability to remove or add for your comfort. The softness/firmness is just right once you figure out your comfortable mix. However with having foam and poly blend, there is no cooling. Those tiny blue specs do nothing but add color to stuffing. Both my husband an myself wake up because our head is hot. Moving around alot helps with that but doesn't offer a restful sleep. I do like that it has a cover over the pillow so you have 2 zippers to go through to remove stuffing. This prevents waking with foam all over your bed. Overall I would have given a better review if actually offered the cooling effect. I could have saved money an just purchased the cheaper pillow they offer.

Tired of bad sleep try this pillow :)
Size: Sapphire Queen
Never owned a nice or expensive pillow finally after a good 25 years of super cheap pillows finally decided to try a nice one and see if there is a big difference and see what all the woot is about anyways in my opinion I am a side sleeper and I now just use this instead of multiple pillows and I can safely say it works very well seems too cool a little and is very comfortable plus bonus they give you extra fluff if you want to add more or replace but straight out of the box was absolutely perfect for sleeping I am insanely picky about it will ABSOLUTELY BUY THIS AGAIN 🥰🥰🥰 firmness absolutely perfect as is

Flattened out a little over a month or using it
Size: Sapphire Queen
Figured I would wait a month or 2 before leaving a review. At first. The pillow was great. Very comfortable. Held up nice. Nice and firm and gave great support. After a month. It started to flatten out. Had to re-fluff it only to have flatted out faster this time. Now no matter how many times I fluff it. It doesn’t give the proper support any longer. I’ve bought 2 of these and they are identical. So it can’t be just a fluke for the 2 i have. I’m regretting the purchase as the price was fair when I bought them. But not any longer as they are not the same.

Amazing - Stop Scrolling and Buy This Pillow
Size: Queen (Pack of 1), Color: White
I have been an Amazon customer ever since the very beginning, and this is my first review. Not because I haven’t purchased tons of amazing things (and a few bad ones), just never felt the need. However, I researched pillows for longer than I care to admit, and decided on this one. I’ve had it for about six months and absolutely love it. No lie, I genuinely look forward lying my big head on it after a long day. I am a side sleeper, but flip flop all around through the night and it’s great in every position. Pros: Stays nice and cool, which is soothing regardless of the time of year. Has a sort of quilted textured pattern on the zip up cover, gives it a luxury feel, that breaths nicely even when a pillow case is added. The fill is fully adjustable to your preference. I knew it came with extra filling but was worried it would not be enough. Wrong. It was very full and I ended up taking some out until it was perfect. It comes vacuum sealed and suggests it may take some time to fully take shape. However, I found it to be about 90% almost instantly and was sleeping on it a couple hours later. There was no unpleasant scent sometimes associated with memory foam items. The foam itself is very nice, a mix of what appears to be shredded and cotton candy cloud like. Very brilliant idea, as it is somehow supportive, soft and firm all at once. The affordability of this pillow compared to some of the others in this category can’t be overstated. Oh, and the packaging was very thoughtfully and securely done. If you are like me, an over thinker, I would suggest just taking this for a spin. It’s amazing. I’m not a bot, or working for the company. I’m just truly satisfied, love this pillow, and have been sleeping great.

It's the perfect pillow!
Size: Queen (Pack of 1), Color: White
I purchased this pillow specifically for its customizable fill feature, which allows you to add or remove stuffing to suit your personal comfort needs. Due to the unique curvature of my cervical spine—forward at the neck rather than backward—I require a soft, semi-flat pillow rather than one that is thick or firm. Additionally, I often experience ear discomfort by morning, so a gentler surface is essential. Upon adjusting the fill, I was pleasantly surprised by the generous amount of stuffing included. There was enough to fill an additional pillowcase, and I estimate it could easily create four to five more pillows. The ability to modify the pillow’s firmness at any time is an outstanding feature that makes it adaptable for a wide range of preferences and sleep styles. This pillow has exceeded my expectations in both comfort and versatility. I highly recommend it to anyone seeking a personalized sleep experience.
