Our Verdict
Tailwind is an endurance fuel first and electrolyte supplement second -- 25g sugar and 100 calories per scoop are designed to fuel long-duration exercise, not daily hydration. The ingredient list is commendably simple and clean (9 ingredients, organic flavors, no fillers), but the electrolyte amounts are low relative to the calorie load: only 14mg magnesium from the poorly-absorbed Oxide form and 26mg calcium from Carbonate. Athletes using this for 3+ hour efforts will appreciate the simplicity; anyone seeking daily electrolytes should look elsewhere.
