Some flavors have CAFFEINE, some don't
The REI website does not indicate this, but most of the flavors contain caffeine. I know that the green Lemon Lime does NOT have caffeine, so that's the one I buy.It's a GREAT product for use in Camelbak bladders to avoid having to clean them thoroughly after every use, unlike sugar-containing supplements. Also, I get no cramps after 8 hours on the trail when I use this, unlike plain water. It mixes on its own due to fizzing and does not go bad if you leave the bladder unrefrigerated for days. Downsides are (1) it is VERY expensive [$] to treat one 100oz bladder with what is essentially 1/2 cent worth of minerals) and (2) carrying the entire thick plastic tube of 12 tablets is uneccesary weight in a backpack; I would prefer foil pouches containing 2 tablets if available.
Pricey but worth the $$
I use a Camelbak fairly regularly in the normal course of my work. The "Gatorade" type drink powder my employer provides A) contains *a lot* of sugar and makes me ill and B) makes a huge mess in a Camelbak if it isn't cleaned throughly and regularly!
Elixir doesn't make a mess, is easy to use on the move in both a hydo pack and water bottles, and tastes pretty good.
I've been using this since the summer of '08 and found that 2 tabs in a 32 oz. Nalgene, 5 in my 3 L. Camelbak work well for me.
The price is why I didn't give it that 5th star as it's expensive at over $4/gal but the convenience is worth it.
Road Cyclist, Love This Elixer
When I'm cycling for my long workouts (>3hrs), these tablets in my camelbak really give me that extra boost of energy. I find that if I fill my camelbak bladder w/ about 1/3 of ice cubes then H2O, then mix in 4 tabs for 100 oz. It's an amazing difference than just going w/ plain H2O. I do carry plain H2O in my cycle frame bottles and find that I will deplete my entire water source by the end of my workout. (Note: When running, I did find that the ice cubes can be an annoying jiggle.)
India is a wonder to survive.
This stuff is great, went for several days on just this stuff out in Bengal India when I had a major case of bacteria in the gutt from water and food. It let me survive.
And People, It tastes a lot better than any dry electrolyte that I could get my hands on there.
Any seriouse Trekker should consider this, especially if you are a lone trecker.
It is pricy but so worth keeping in your bag!!!
YOU don't have to use it full strengh to get the bennies form it. Carry it.
Beats Gatorade hands down
I used to carry Gatorade powder on long desert hikes (four or five days), but I got tired of the sugar crash and cleaning gunk out of my bladder. I switched to this product to get away from the sugar, and I am very pleased with it. I use it after running (4.5 miles or so) and on desert hikes. No sugar crash, and no mess to clean up. It's expensive, but very good.
I threw these into my backpack for a recent high altitude backpack with a group. Despite lots of water, the first day was tough. Three of us developed some dehydration and nausea and these worked for each of us. I put one tablet in a liter of water and the Orange Alert flavor tastes great. I personally appreciate the caffeine as I usually drink diet coke. I'll be buying more soon.
Good hydration- too much sodium!
I liked the ease of use and sugar-free composition of the elixir tabs. The taste was okay too. However, I noticed that my fingers swelled quite a bit when I used these on a long hike, more than with a competing brand. I'd recommend these, but I would mix them to a less concentrated amount to lessen the amount of sodium in each drink.
I would buy this product again
My 2 teenage children are diabetic and this is a GREAT way to give them their electrolytes when they are sick without giving them extra sugar or worse---corn syrup! They also enjoy this during sports (horse vaulting/running/tennis/swimming) Pedialyte is many times more expensive and tastes terrible!! My husband is a competitive cyclist and found this a great find for himself also!!
I used these while working on water projects at the peak of the dry season in India. The daytime temps were around 110 and the lows were in the upper 90s. Multiple days working hard and hiking in this weather made these a go-to product.
Better than Gatorade....
Pleasant lemon-lime taste. Don't use too much or it can overwhelm you. I like to add it the night before and refrigerate it.
No aftertaste in my Camelbak after cleaning.
Better than Gatorade! Doesn't have that awful sweet taste...
