In recent years there has been a lot of talk about gut bacteria, so I thought I would ask some questions.
1. What do you think of probiotic supplements?
2. What are your favorite probiotic foods?
3. Are there probiotic drinks?

A comment from Friday when Daniel asked a question about a rehydration tablet added to morning water. I’m not a dietician or a sports performance person. This is just my opinion as a medical doctor (to be fair, we’re probably kind of nihilistic about a lot of these things since we bad stuff all the time and western medicine rarely takes a preventative approach), so take it for what it’s worth.
Most people are dehydrated when they first wake up, so there’s logic to rehydrating oneself there. But unless you are drinking saline solution, it is unlikely you will rehydrate yourself with just a glass of water and some added electrolytes - there is not enough of them there to match the concentration of your blood. And if your serum electrolytes concentrations are that low enough that they need repletion, chances are, you are sick with something else. Deciding whether or not to use a dehydration tablet will be the least of your problems. So, you’re probably better off saving your $ and just drinking some water and eating something, since we get most of the electrolytes from the food we eat, anyway. The body does a pretty remarkable job at regulating itself, and when we go tinkering here and there, more often than not, we muck it up or just spend a lot of money for expensive urine. But, that said, if you like the taste of the tablet, and it causes you to drink more water, then it may be worth it. The real value of those sport rehydration drinks is probably not so much in the proportions of the electrolyte ingredients (which to a dehydrated person, is better than nothing, but as mentioned, is unlikely to be concentrated enough to really get the job done) but more that if they taste good, you’re more likely to rehydrate yourself. The added sugar will probably also give an energy boost that may help in scenarios like the one about the long belt test where eating may not be an option.
