# Fitness and Energy ## What Are Fitness and Energy Supplements? Fitness and energy supplements are dietary products designed to support physical performance, endurance, strength and overall vitality throughout the day. This category includes pre-workout formulas, energy boosters, electrolyte mixes, creatine, B-group vitamins, caffeine-based products, amino acids and carbohydrate or vitamin drinks. Fitness and energy supplements are usually available as powders, capsules, tablets, shots or ready-to-mix sachets with clearly defined daily dosages. They are intended to complement a balanced diet, regular training and healthy lifestyle habits, not to replace them. ## Benefits of Fitness and Energy Supplements Fitness and energy supplements help support normal energy-yielding metabolism, reduce tiredness and fatigue and aid performance during training or an active day. Pre-workout products often contain ingredients such as caffeine, amino acids and vitamins to support focus, motivation and endurance. Electrolyte and carbohydrate drinks can help maintain fluid and mineral balance and support energy levels during prolonged activity. Creatine is widely used to support strength and power in high-intensity training, while B-group vitamins and magnesium contribute to normal energy production and muscle function. When used correctly alongside a varied diet, fitness and energy supplements can help you get more out of your workouts and daily activities. ## Uses of Fitness and Energy Supplements Fitness and energy supplements are commonly used by gym-goers, runners, cyclists, team-sport athletes and anyone with a demanding schedule who wants extra support for performance and alertness. Pre-workout powders or shots are typically taken 20–30 minutes before training, while electrolyte or carbohydrate drinks are used during or after exercise. Daily energy and vitamin products can be used in the morning or around times of increased workload. On our category page you can explore a wide range of fitness and energy supplements – from creatine and amino acids to pre-workout blends and electrolyte powders – and choose products that best match your goals, training style and lifestyle. ## Fitness and Energy Supplements: Side Effects and Overdose Fitness and energy supplements are generally safe when used according to the instructions, but, as with any supplement, individual reactions are possible. Products containing caffeine or other stimulants may cause restlessness, rapid heartbeat or sleep disturbances, especially if taken in high doses or late in the day. Some people may experience digestive discomfort or sensitivity to certain ingredients such as sweeteners or specific amino acids. It is important not to exceed the recommended daily dose stated on the packaging and to consider total intake of caffeine and other active ingredients from all sources. People with heart conditions, high blood pressure, chronic illnesses, those taking prescription medications, as well as pregnant and breastfeeding women should consult a doctor or healthcare professional before using fitness and energy supplements. ## Where to Buy Fitness and Energy Supplements in Estonia?
