Memories from our day–guard family

“We use day–guard on tour to stay healthy and protected while still having a good time. It’s a key part of our routine.”

"I love the mango flavor and the support feels real. day–guard is clearly more than just electrolytes (which I used to rely on)! I handed these out at my housewarming and got texts the next morning from friends saying they felt great. It’s my new going-out essential."

"I’m not a heavy drinker but caught a blurb about day–guard in the Boston globe. It was a piece about the two young men who started the company and not a review or opinion as to its efficacy. I decided “what the heck” and ordered some and now I don’t have a couple/few beers after golf without it."
