7 interactions related to athletic synergy
beta-alanine + sodium bicarbonate
Beta-alanine raises intramuscular carnosine for intracellular pH buffering, while sodium bicarbonate raises extracellular bicarbonate for blood pH buffering. The two buffers act in different compartments, producing additive effects on high-intensity exercise capacity.
creatine + beta-alanine
Creatine boosts phosphocreatine stores for ATP regeneration during short maximal efforts, while beta-alanine raises muscle carnosine to buffer the H+ accumulation that limits efforts lasting tens of seconds to a few minutes. The two address different limiters of high-intensity performance.
leucine + carbohydrates
Leucine activates mTOR-driven muscle protein synthesis and stimulates insulin release. Combined with carbohydrate, the insulin response is amplified roughly 2.5-fold over carbs alone, which suppresses muscle protein breakdown and increases amino acid uptake.
electrolytes + carbohydrates
Sodium and glucose share the SGLT1 cotransporter in the small intestine; their co-ingestion drives faster water absorption than either alone (the basis of oral rehydration therapy). Carbohydrate also delays gastric emptying slightly while providing exercise fuel.
citrulline + arginine
Oral arginine has poor bioavailability due to extensive first-pass metabolism. Citrulline bypasses the liver and is converted to arginine in the kidneys, sustaining elevated plasma arginine. Combined oral dosing produces a faster and higher plasma arginine peak than either alone, increasing nitric oxide synthesis.
creatine + carbohydrates
Co-ingesting creatine with carbohydrate spikes insulin, which upregulates the sodium-dependent creatine transporter and Na+/K+ pump activity in skeletal muscle, increasing intramuscular creatine retention.
bcaa + carbohydrates
Carbohydrate co-ingestion with branched-chain amino acids amplifies the insulin response, which suppresses muscle protein breakdown while leucine-driven mTOR signaling stimulates protein synthesis. Carbs also replenish glycogen depleted during training.
