Coconut water

ditto.

I don't know if it actually is best for rehydration though.  If you're drinking it before a workout you aren't really "rehydrating", aren't you just hydrating?

Frankly I just drink it cause of marketing and it's different and new.  no clue if it does what it says.

I have only tried ZICO and I love it.  However, it comes in a box or a bottle, and the bottled stuff tastes weird.... but out of the box (and cold) it is just glorious.

I am a big fan of cocunut anything...except cocunut water. I can stomach a lot of things, but not this...and i have really tried. But that's just my perspective only. Many people love it.

If you are enthralled by the marketing campaign and that reeled you in, have at it. Word is it's good for you, but it's a wonder people managed to rehydrate prior to cocunut water based on what i hear.

It is not really the best for rehydration.  For electrolyte replenishment Gatorade or any other sport drink is much better than coconut water, the only thing that coconut water has going its that is a good source of potassium.

If you are doing moderate exercise, you are better off sticking with water and saving the money.  If it is more intense activity, Gatorate will be cheaper and far more effective.  Coconut water is just the most recent trend.

As far as taste i cant give an opinion in regards to the different brands, i havent tried the canned stuff.  I drink the natural coconut water as i have coconut trees and that is extremely refreshing on a hot day

I love coconut anything, including water if it is cold.  However, I have started mixing some of the powdered gatorade in with it for a little of the salt.  I also mix powered amino acid to help the muscles recover and energize them on long rides or runs.

I find its best when mixed with Gin...

Great for a mid ride pit-stop!  Pull into a bar, grab a couple Gin and Coconut water's maybe some jerked chicken and your good for the ride back home!  Best you find a bar that is actually cracking open coconuts though, skip that bottled stuff!

It is great if you are into the newest fad, cause that is all it is. Otherwise, make a great fruit smoothie after a workout and get a lot more carbs, cals, vitamins, etc.

Also good but would require a bit of rum instead of Gin.  Depends what your in the mood for.

I high suggest you do NOT try the mango flavor one by Vita. Gross! But I find them very good a making you not cramp with all of the potassium I am bad about not drinking enough water so I cramp a lot.

YUC

Blasphemy!! There is nothing more refreshing after a long run/ride than chugging a box of coconut water...

Here's one reason: it's delicious.

Your research has already proven to be wrong. (Besides, for every nutritionist who says it's not beneficial you're gonna find 10 more that say it is. Just because you heard it on NPR doesn't mean it's true.)

Well, I think there might be A reason. If people like it, then by all means drink up. But they do need to realize it's not going to provide any magical powers to suddenly make you not cramp up. 

You are correct, drink water and eat right and you will be fine. I also happen to think it tastes like **** so personally, I have no reason to drink it. 

Well it only costs me 6 pesos/liter (what I pay my youngest to procure for me) and since it is straight from the coco I guarantee it is without any additives.  So i'll stick wiht my coco water, thanks.    tastes GREAT.

Also, most packaging is non reusable and most communities don't recycle them.
