I've been using Optimal Electrolyte Sticks from Seeking Health daily for a few months now, and the berry flavor has definitely become my go-to. Each stick mixes effortlessly, no clumps or odd aftertaste, and the taste is genuinely refreshing and satisfying without being overly sweet. I notice a real boost in my energy levels, whether I'm working out, running errands, or just getting through a busy day. I also love the convenience of the single-serve sticks since they're perfect for tossing in my gym bag or taking on the go.
