Would you say that it is a safe assumption that drinking NUUN tablets in moderation, and not as an every day, every drink hydration option, has no more damaging impact to your teeth than those who eat fruits & vegetables or drink soft drinks containing citric acid?
Or are you saying that drinking one NUUN tablet does exponentially more damage than drinking a Coke or eating a lemon?
Are you replacing sodas and fruits with nuun, or are you drinking it on top of them? Of course you can destroy your teeth in many ways. Unnecessary citric acid is just one of them.
The problem is, that swallowing a lot of citric acid in one go (like with a fruit salad or soda) is - even if the total amount is higher - better for your teeth than sipping it for hours on the bike.
Sipping on coke for hours is not good for your teeth, neither is nuun.
But with the argument, “People drink more, because it has flavour” I rest my case. Really. If you can’t drink water to thirst, which has shown to prevent dehydration (Noakes among others beside thousends of years of evolution), than it is defintely better to drink another diet drink, than die of dehydration.
About the potassium and other minerals, just show us the data. If it is ergogenic, just show the data … I know the studies on water, carbs, sodium and caffein. And a lot of marketing claims on a lot of other stuff (from just about any amino acid, whey protein, just about any mineral or vitamin …) is just not proven to be ergogenic.
But keep drinking it, its part of what we love about America, a complex technical and chemical product, that delivers nothing we need, but restores hydration by making water taste more palatable. And there is a grain on truth in that story, if you exercise really lots and drink lots of plain water, you can get hyponatremia which is nasty. But if you exercise that long, you need carbs anyway … Whatever … Cheers
I stay with water, beer and coffee. And if I have to drink a lot (4hr ride in the heat) I will add some carbs (fruit juice + maltodextrine or sugar/honey) and salt to my water.
