Running is hard enough as it is, don’t make it harder on yourself - and stay hydrated! The potion formula has 1,000mg of sodium, 200mg of potassium and 60mg of magnesium. They have a balanced formula tailored to an active lifestyle. The sodium in the product helps boost hydration. The magnesium is great for muscle recovery. I love to use Potion to hydrate on my runs, hydrate after my runs. Just mix, sip and go.
