"We have tried to help him pick himself him up and we wrote to him telling him to keep his head up," said Koepke, the former Germany international.
Head coach Joachim Loew, team manager Oliver Bierhoff and Koepke, all currently in northern Italy for a World Cup training camp, sent Karius a text message following Saturday's final in Kiev.
Koepke, a World Cup winner and European champion with Germany in the 1990s, slammed certain extremely critical remarks of the 24-year-old Karius in the wake of his two glaring mistakes.
"It's very borderline and totally incomprehensible on the part of experts with whom I played myself," said Koepke, notably taking aim at former Germany star Lothar Matthaeus who called it the "worst goalkeeping display in the last 20 or 30 years".
"It's a very brutal thing to experience," added Koepke. "I hope he will be supported by Jurgen Klopp and by Liverpool so he can get through it."
