It gets hot here in Phoenix. Very hot. And if you are active, and sometimes even when you aren't, it's super easy to get dehydrated.
During the bigger heat waves, and when I just cannot seem to 'cool off' in late summer, I have a hard time getting rehydrated no matter how much water I have been drinking. Some days I theorize that I have the summer version of Seasonal Affective Disorder...I get lethargic, grumpy, and have a poor appetite. I tend to sweat a lot too, but that is unrelated, it just exacerbates my electrolyte-loss. So, anyway, I drink a lot of water, before, after, and during anything to prevent being dehydrated. It doesn't always work.
Last summer, I started adding some electrolytes on the the days when I felt in a hot funk and it made a difference. I felt noticeably better. I hate the taste of Gatorade and the other sports drinks, and I definitely don't need the sugar. So I found an alternative, Trace Minerals Electrolyte Stamina. I don't take the supplement often, but I've found that when I do, I feel better afterwards. Trace Minerals Electrolyte Stamina pills are completely vegan. You can find the Trace Minerals Electrolyte Stamina at Sprouts and on the Trace Minerals website. I'm not sure where else you can find them, but I imagine they might be at Whole Foods and local health stores.
We should have options, so here are some other vegan electrolyte replacement products that come in other forms. I haven't tested them myself, but they seem promising.
