Cheapest form of balanced electrolytes for daily use? - Lemmy

Title says it all. I’m looking for serious electrolyte powder, drink, supplement, DIY. For when water isn’t hydrating enough due to an underlying medical condition. I hope this is OK to post. I can easily drink 1.5 gallons a day and gain no relief from horrible dehydration. I’ll also share my water bottle soon as I can!

I can’t speak to it being cheap or expensive relative to other options but I buy Tailwind to mix with water when I’m going on long hikes.
I’ll check them out. Thanks.
