Creatine is among the most studied supplements in sports, with evidence that it can boost strength, improve high-intensity performance, and help muscles recover. Now researchers are asking a harder question: Could the same compound that fuels a workout also help treat depression?

Medical professionals agree with Rep. Tom Kean Jr. (R-New Jersey) that depression is hard to grapple with, and that discussing mental health still carries a stigma.

Creatine, one of the world’s most popular fitness supplements, is best known for helping build muscle and improve strength. But scientists are now exploring a surprising possibility: it could help with depression.

It is “difficult to fully understand how powerful this illness can be,” said Rep. Tom Kean Jr.

The model later apologized for "startling" or "worrying" her followers, writing, "I know it sounds jarring, but in full truth it's my reality."

Rep. Tom Kean Jr. (R-New Jersey) returned to work Tuesday after missing votes since early March. His absence had fueled GOP worries about the fate of his swing seat in November.

Creatine is best known as a muscle-building supplement, but scientists are now investigating whether it could also help treat depression by boosting the brain's energy supply. A new review examined five randomized clinical trials involving 238 participants and found mixed results.

Representative Thomas Kean Jr. announced he had been hospitalized for depression. More than one in four U.S. adults report having been diagnosed with the condition.
