Yes, but they’re handled like any other medication. Your Scout needs a letter from an MD, DO, physician assistant or nurse practitioner that lists the camper, the supplement, the dose and the times to take it. Your unit checks the supplements and the letter in with the Med Lodge on Sunday, along with the rest of your medications, and Med Lodge staff give your Scout each dose during the week. Leaders and parents can’t hand them out.
Without the letter, the Med Lodge can’t give them out. They stay locked up at the Med Lodge for the whole week, and you get them back when you leave.
