ABOUT Endurance Athlete Supplement Stack
Endurance Athlete Supplement Stack
The Endurance Athlete Supplement Stack is a stimulant-free performance and focus system designed to support sustained training output, mental clarity, and recovery during high-volume endurance work.
Combining Metabolic Amino Complex, Brain Storm, and Focus Sustain, this stack supports both the physical and cognitive demands of endurance sport without relying on caffeine or harsh stimulants.
Built for athletes who train frequently, compete regularly, or follow structured endurance programmes, this stack supports energy metabolism, hydration balance, muscle preservation, and focus across long sessions and multi-hour efforts.
What This Stack Is Designed to Support
The Endurance Athlete Supplement Stack helps support:
- Sustained endurance performance
- Normal muscle function during prolonged activity
- Focus, concentration, and mental drive
- Hydration and electrolyte balance
- Cellular protection from exercise-induced oxidative stress
- Recovery during high training loads
Stimulant-Free Performance & Endurance Support
At the core of the stack is Metabolic Amino Complex, a non-stimulant EAA and BCAA formula designed for endurance training and recovery.
Metabolic Amino Complex supports:
- Normal muscle function through a full spectrum of essential amino acids
- Normal protein synthesis via an elevated BCAA 8:1:1 leucine ratio
- Circulation and muscle buffering through L-citrulline and beta-alanine
- Normal energy-yielding metabolism with B-vitamins and trace minerals
- Hydration and electrolyte balance during prolonged exercise
- Cellular protection through antioxidant compounds
With only 11 calories per serving and no stimulants, it can be used pre-session or sipped throughout training.
Cognitive Performance & Mental Stamina
The stack includes Brain Storm and Focus Sustain, two stimulant-free nootropic formulas designed to support mental performance during long, demanding sessions.
Cognitive support includes:
- Amino acids such as L-tyrosine and acetyl L-carnitine to support neurotransmitter function
- Alpha GPC and choline sources to support focus, reaction time, and decision-making
- Adaptogenic botanicals including rhodiola, ashwagandha, bacopa, and lion’s mane
- L-theanine to promote calm, balanced focus without overstimulation
- B-vitamins to support nervous system function and energy metabolism
These formulas help maintain concentration, pacing discipline, and mental composure during extended training and competition.
Antioxidant, Metabolic & Recovery Support
Across the stack, antioxidants and bioactive nutrients support the body during high training volumes.
Key benefits include:
