I don’t agree it. Caffeine can’t dehydrate.Reasons as following.
- Caffeine is small dehydrating agent. People can exercise patience it after 4 to 5 day.
- Like water, cola, tea… They are same with coffee. All is small dehydrating agent.
- We have some experiments prove that caffeine can’t dehydrate.
That’s it. So I think caffeine can’t dehydrate.
