Research overview of lactate threshold physiology and compounds studied for endurance performance — beta-alanine, sodium bicarbonate, L-carnitine, citrulline, BCAAs, and training interventions that raise the lactate threshold and delay fatigue in aerobic athletes.

Research comparison of L-Citrulline and L-Arginine for nitric oxide production — why citrulline outperforms arginine despite not being the direct NO precursor, dosing protocols, citrulline malate vs pure citrulline, Agmatine interactions, and performance applications.

Research overview of astaxanthin — the marine xanthophyll carotenoid with exceptional antioxidant properties, mitochondrial membrane positioning, endurance performance research, skin UV protection, and anti-inflammatory data, comparing krill vs synthetic forms.
