Formulation Notes
Twinlab Endurance Fuel is a caffeine-free serious multi-stage formula that anticipates the body’s needs for pre, during and post-race nutrition to sustain optimal performance, enhance endurance and speed recovery.
ENDURANCE Stage 2 Endurance Blend:Beta-alanine supports muscular endurance, power and output; a powerhouse carb blend releases energy faster (waxy maize, glucose), sustains it (maltodextrin), and acts as an energy reservoir to help you finish strong (isomaltulose). Electrolyte blend aids proper hydration and helps you overcome heat stress.*
RECOVERY Stage 3 Recovery Matrix: Time-released whey and casein proteins, at a 4:1 carb-to-protein ratio, help prepare muscles for faster recovery even during activity.*
POWERED BY BETA-ALANINE THE ENDURANCE INGREDIENT
No Artificial Colors No Artificial Flavors
Caffeine Free
Clinical studies indicate that beta-alanine raises the anaerobic threshold in endurance athletes without any weight gain and assists power athletes to delay fatigue.* Endurance Fuel combines beta-alanine with a host of other clinically-tested nutrients to enable extended performance and greater output.
