What supplements or electolyte replacements go up the mountain with you? What are you using to hydrate and recover? Is most of the stuff they are pushing "hype" or do they work?
I really like the Wilderness Athlete Hydrate & Recover.......it does work for me. In fact, there is a noticeable difference in how I feel overall even at home taking it. I also throw in a packet of Emergen-C Electromix at least once a day when I'm hunting. I'll use four servings a day of the H&R. I use a serving in 16oz of water. If you like Lemon-Lime they have 60 serving tubs on sale for $17.95 (reg $29.95). I don't like Lemon-Lime, and apparently nobody else does either.
I personally like Skratch Labs Exercise Hydration mix. Lemons and Limes tastes great. I started using it because I got some for free but legitimately can tell a difference in the way I feel. Admittedly, I use it mostly for long mtn bikes rides where I'm generally sweating a lot, but I'm sold on it.
