  • 500mg Acetyl-L-Carnitine HCl per capsule: The acetylated form of L-carnitine — readily crosses the blood-brain barrier to deliver fuel to brain cells.
  • Mitochondrial energy support: Carnitine shuttles fatty acids into mitochondria for energy production — supports cellular energy at the foundational level.
  • Cognitive function and focus: Acetyl group supports acetylcholine production and brain cell communication — widely used as a nootropic for mental clarity.
  • Stacks well with other nootropics: Part of the Cognitive Power Stack alongside Alpha GPC and L-Tyrosine. Also an ingredient in Brain Drive.
  • Recovery and physical performance: Supports recovery from intense training and may reduce exercise-induced fatigue.
  • NSF Certified for Sport®: Independently tested for banned substances. Vegan, gluten-free, GMO-free. Take 1–2 capsules daily in the morning or early afternoon.

Momentous Acetyl L-Carnitine delivers 500mg of Acetyl-L-Carnitine HCl per capsule — the acetylated form of L-carnitine that crosses the blood-brain barrier to support mitochondrial energy production and cognitive function. Part of the Cognitive Power Stack alongside Alpha GPC and L-Tyrosine.

L-Carnitine is essential for transporting long-chain fatty acids into mitochondria, where they are converted to ATP for cellular energy. The acetylated form (ALCAR) adds an acetyl group that allows easier passage into the brain and contributes to acetylcholine production — the neurotransmitter for learning and memory.

Key benefits:
• Mitochondrial energy — supports fatty acid metabolism for sustained cellular energy
• Cognitive function — supports mental clarity, focus, and memory
• Brain cell support — supports neuronal energy and acetylcholine production
• Recovery from training — may reduce exercise-induced fatigue and improve recovery
• Healthy aging — mitochondrial function declines with age; ALCAR supports cellular vitality

ALCAR vs L-Carnitine:
While L-Carnitine works peripherally for fatty acid metabolism, ALCAR's acetyl group allows it to cross the blood-brain barrier and influence cognitive function. For brain support, ALCAR is the form of choice.

Take 1–2 capsules (500–1000mg) daily in the morning or early afternoon. Taking later may interfere with sleep due to neurotransmitter and mitochondrial activity.

Momentous Acetyl L-Carnitine is NSF Certified for Sport®, vegan, gluten-free, and GMO-free.

What's the difference between L-Carnitine and Acetyl L-Carnitine?

L-Carnitine primarily works peripherally to transport fatty acids into mitochondria for energy. Acetyl-L-Carnitine (ALCAR) has an acetyl group attached that allows it to cross the blood-brain barrier and influence cognitive function and acetylcholine production. For brain support, ALCAR is the preferred form.

What does it do?

ALCAR supports mitochondrial energy production, cognitive function, mental clarity, and memory. It's often used as a nootropic for sustained focus and brain health, and may support recovery from intense training.

When should I take it?

Take 1–2 capsules (500–1000mg) daily in the morning or early afternoon. Some users find it energizing, so taking it later in the day may interfere with sleep.

How is this different from Brain Drive?

Brain Drive is a multi-ingredient nootropic that contains ALCAR (500mg) alongside L-Tyrosine, Citicoline, Bacopa, and B-vitamins. This standalone Acetyl L-Carnitine product gives you the same ALCAR dose without the other ingredients — useful for custom stacking or single-ingredient supplementation.

Is it third-party tested?

Yes. Every batch is NSF Certified for Sport® — independently tested for banned substances and label accuracy. Vegan, gluten-free, GMO-free.
