Acetyl-L-carnitine is a naturally occurring amino acid that increases cellular energy, boosts mood, and optimizes brain function.*

Acetyl-L-carnitine is a naturally occurring amino acid that increases the neurotransmitters norepinephrine and serotonin, which play essential roles in boosting mood and optimizing brain function. It fuels mitochondria increasing cellular energy. It directly enhances neural transmission by stimulating synapses or blocking post-synaptic inhibition. And it synergizes other nootropics, potentiating the overall effects of the formula. Using acetyl-L-carnitine feels like it increases your electrical "wattage," so you burn brighter and longer.*

  • Improves mood, social interaction, and verbal fluency*
  • Increases energy production in the mitochondria, boosting physical and mental energy for several hours*
  • Increases mental processing speed, learning rate, attention span, short-term and long-term memory, and facial recognition*
  • Increases glucose levels in the brain*
  • Stimulates brain cells prompting them to grow more connections to other neurons*


Acetyl-L-carnitine (ALCAR) is a naturally occurring amino acid that's essential for the proper functioning of mitochondria. While your body produces it naturally, it sometimes struggles to produce enough.

This is why people who take extra ALCAR often experience incredible benefits such as increased energy, enhanced cognition, and improved focus. Acetyl-L-carnitine is so effective that it's injected intravenously to emergency room patients suffering from reduced blood flow to the brain.
