Arachidonic Acid

Arachidonic acid is involved in muscle growth signaling and supports muscle repair processes.

Clinical Dose: 500mgFound in: 11 products

What Does Arachidonic Acid Do?

Arachidonic Acid (ARA) is a polyunsaturated omega-6 fatty acid that serves as a primary building block for the synthesis of prostaglandins, which are crucial signaling molecules in the muscle hypertrophy process. Unlike many supplements that aim to reduce inflammation, ARA leverages the body's natural inflammatory response to trigger growth and adaptation.

  • Muscle Growth Signaling: Triggers the release of prostaglandins like PGF2a after resistance training, which directly stimulates the mTOR pathway for protein synthesis.
  • Enhanced Muscle Repair: Facilitates the acute, localized inflammatory response necessary for repairing micro-tears in muscle fibers caused by heavy lifting.
  • Increased Power Output: By optimizing the cellular environment for adaptation, it helps maintain high-intensity performance and strength gains over long training cycles.
  • Improved Nutrient Partitioning: Some research suggests it may help direct nutrients toward muscle tissue repair rather than fat storage during recovery phases.

Clinical vs. Gym Bro Dosing

TierDoseNotes
Maintenance250mgSuitable for off-days or lighter training phases to maintain levels.
Clinical Standard500mgThe most common research-backed dose for supporting muscle hypertrophy.
Performance1,000mgOften used by advanced athletes to maximize the acute inflammatory response.
Upper Limit1,500mgHigh dose; typically requires cycling (8 weeks on, 4 weeks off) to avoid chronic issues.

Key Insight: To maximize the effectiveness of Arachidonic Acid, it should be taken approximately 45 minutes before your workout. This ensures peak plasma levels coincide with the mechanical stress of lifting, triggering the necessary prostaglandin response for growth.

Side Effects & Warnings

  • Increased Muscle Soreness: Because it promotes the acute inflammatory response required for growth, you may experience more intense and longer-lasting DOMS (Delayed Onset Muscle Soreness).
  • Joint Discomfort: In some individuals, the increase in systemic inflammation can lead to temporary joint stiffness or minor aches.
  • Gastrointestinal Distress: High doses of fatty acids can occasionally cause mild nausea or indigestion if taken without a small amount of food.

Tip: Avoid taking anti-inflammatory supplements like high-dose Fish Oil or NSAIDs (like Ibuprofen) immediately around your workout when using Arachidonic Acid, as they can counteract the muscle-building signals this ingredient is designed to create.
