Taking creatine supplements, even for several weeks or at different doses, doesn't make your brain work better if you're a healthy person — whether you're a kid, a vegetarian, or an older adult.

Taking creatine supplements doesn't seem to help people with fibromyalgia, bipolar depression, or Huntington’s disease think better or remember things more clearly, based on studies that looked at it.

Taking creatine supplements can help you build more muscle and get stronger because it helps your muscles recharge their energy faster during intense workouts like lifting weights or sprinting.

This technique works well for calf raises and leg extensions, but it’s too risky or hard to do safely with exercises like squats or bench presses unless you have a spotter.

Doing calf raises with a shorter range of motion while your foot is pulled up might make your calf muscle work harder in that position, which could help you build more muscle in fewer sets.

You can build the same amount of calf muscle by doing shorter, harder reps that go only partway up—instead of full reps—while doing about half as many sets. It’s like getting the same result with...
