Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Glucose is scientifically used to support bodybuilding primarily as a rapid source of energy, especially around workouts. During intense exercise, muscles utilize glycogen—a storage form of glucose—for fuel. Consuming glucose before, during, or after workouts can help replenish muscle glycogen, delay fatigue, and support recovery. Scientific studies have shown that carbohydrate ingestion, including glucose, can enhance exercise performance by maintaining blood glucose levels and sparing muscle glycogen, particularly in prolonged or high-intensity activities.

Post-workout, glucose is often combined with protein to stimulate insulin secretion, which in turn promotes amino acid uptake and muscle protein synthesis. This combination can help optimize recovery and support muscle growth. While the use of glucose is supported for its ergogenic and recovery effects, it is not essential for all athletes or bodybuilders, and the benefits may depend on workout intensity, duration, and overall dietary context.

The evidence is robust for glucose’s role in energy metabolism and recovery, but its direct impact on muscle hypertrophy (growth) is secondary to its role in supporting training performance and recovery. Most recommendations for glucose or simple carbohydrate use are focused on peri-workout nutrition rather than as a standalone supplement for building muscle. Therefore, the scientific rating is 3, reflecting moderate support for its use in specific bodybuilding contexts.
