Creatine might be doing more for your brain and bones than you thought.

There’s no research found to back up that dramatic anxiety claim, so that part remains unverified. But other research suggests creatine could give your brain a subtle edge—helping you stay focused, react faster, and feel less mentally drained, especially when paired with mental tasks. When combined with weight training, it appears to help older women maintain hip bone density and preserve muscle mass during hormonal changes like menopause, though it doesn’t work alone—you still need to lift. One study even showed it helped people keep muscle while their arm was stuck in a cast, hinting it might fight muscle loss in stressful situations.
