What Is Biohacking?

Science can make you feel better. That’s the idea behind biohacking, a DIY approach to self-care that uses everything from lifestyle changes to high-tech tools to improve your health. One popular form of biohacking is a group of substances called nootropics, or “smart drugs.” Nonprescription nootropics include tablets, supplements, drinks, and foods. They contain substances that may help boost brain performance. Examples include creatine and caffeine.
