I want electrolytes and amino acids. But I want to suppress sugar and calories as much as I can because I take it in action food. If possible, it's caffeine-free... After searching for something, I finally found an item that 100% met my needs. Moreover, XTEND is safe and stable. It's a little hard to dissolve, but after using it, I feel that the performance during climbing has improved considerably compared to drinking plain water. The flavor is raspberry lemonade. In Japan, there are many citrus flavors, so I bought a berry flavor because it was rare. Although it has an overseas feel, it is a very favorite taste personally. Despite the aroma, it is sweet enough to drink in the hot mountains. and a slightly salty taste. In Japan, there are almost no options other than the major brands such as OS-1 and Aquarius. However, this product has perfect ingredients and is highly portable. Since I only use 1 or 2 bottles per mountaineering trip, if I buy one box, it will last for a whole season, but I think I will buy it again when I run out.
