Pre-workout supplements, also known as preworkouts or boosters, are formulated to enhance endurance, strength, and focus during exercise. They typically contain a blend of active ingredients such as caffeine, creatine, and beta-alanine, which can help increase energy production, delay fatigue, and improve muscle performance. However, it's important to note that individual responses to these supplements can vary, and it's essential to adhere to recommended dosages to avoid unwanted side effects. Additionally, a balanced diet and proper hydration are crucial for optimizing performance and recovery. Always consult a healthcare professional or a sports nutritionist before starting to use pre-workout supplements to ensure they are suitable for your individual needs and fitness goals.
