Aspartic Acid

Original price $29.95
Current price $19.95

Aspartic Acid (or D-Aspartic Acid, DAA) is a non-essential amino acid that plays a key role in energy production, hormone regulation, and brain function. It exists in two forms: L-Aspartic Acid (involved in metabolism and protein synthesis) and D-Aspartic Acid (DAA), which is often linked to testosterone production.


  • Aspartic acid is part of the Krebs cycle, helping the body convert carbs, fats, and proteins into ATP (energy).
  • May help reduce fatigue and improve muscle endurance during workouts.
  • Useful for high-intensity sports like sprinting, soccer, and gymnastics.

Best for athletes needing sustained energy and reduced fatigue.


  • D-Aspartic Acid (DAA) is linked to testosterone production and is sometimes used as a natural testosterone booster.
  • However, research is mixed—some studies show a temporary increase in testosterone, while others show no significant effect in trained athletes.
  • More beneficial for older individuals or those with low testosterone, but less effective in young, healthy athletes.

May help with strength and muscle growth in some cases, but not a game-changer for young athletes.


  • Aspartic Acid acts as a neurotransmitter, supporting brain function, memory, and mental clarity.
  • Helps regulate NMDA receptors, which are important for learning and focus.

Good for athletes needing quick decision-making and focus (e.g., soccer, gymnastics, sprinting).


  • Helps clear ammonia from the body, reducing muscle fatigue and soreness.
  • Plays a role in DNA and RNA synthesis, which supports muscle repair and growth.

Useful for athletes who train intensely and need faster recovery.


Athletes who need sustained energy & endurance (soccer, sprinting, gymnastics).
People looking to improve brain function & focus.
Individuals recovering from intense training.
Older men or those with low testosterone levels (DAA form only).


  • L-Aspartic Acid: Naturally found in foods like meat, fish, eggs, and soy. No need to supplement unless deficient.
  • D-Aspartic Acid (DAA):
    • 2–3g per day for potential testosterone support.
    • Works best when cycled (e.g., 2 weeks on, 1 week off).
Would you be looking into it for energy, recovery, or hormone support for your athlete? It may not be as essential as creatine, beta-alanine, or citrulline, but could still have benefits for endurance and recovery.
