Dietary supplements can be used to enhance athletic performance and are commonly found in pre-workout supplements. Pre-workout supplements aim to increase energy, focus, blood flow and muscle pumps. They often contain caffeine, beta-alanine, creatine and amino acids. However, research on the effectiveness and safety of supplements, especially at high doses used by athletes, is limited. There is also lack of regulation, resulting in variable quality and potential interactions with medications or other supplements. Fat burning supplements typically contain stimulants, herbs and plant extracts to boost metabolism and minimize cravings.
