The SaltStick Caps Plus replenishes lost electrolytes and enhances focus when you're perspiring from heavy exercise. This 100-pack of electrolyte capsules is a great choice for competitive athletes, due to its bio-active ingredients which are allowed by the World Anti-Doping Agency and International Olympic Committee. Each tablet contains 30mg of caffeine and 100 IU of Vitamin D, alongside an optimal electrolyte blend of 190mg sodium, 53mg potassium, 14mg calcium, and 7mg magnesium. The tablets are free of artificial sweeteners and animal-derived ingredients. The capsules are also gluten-free and vegetarian-friendly. SaltStick recommends taking one capsule for every 30 to 60 minutes of intense exercise.
