2024's Top 9 Acetyl L-Carnitine Supplements

Find out what to look for in a quality Acetyl L-Carnitine supplement and what to watch out for

What is Acetyl L-Carnitine?

Acetyl L-Carnitine is a natural derivative of the amino acid lysine and methionine with an attached acetyl group. Given the addition of this acetyl group, the dietary supplement has the ability to easily cross the blood-brain barrier, making it highly bioavailable and ideal for fitness and cognitive benefits.

Uses For Acetyl L-Carnitine

✔️ Athletic Performance 

Acetyl L-Carnitine has been shown to improve athletic performance in three ways:

  • Increased Blood Flow
  • Improved Oxygen Consumption In Working Muscles
  • Muscle Recovery

✔️ Brain Boost

Recent studies have suggested that acetyl- L-carnitine may be effective at increasing the performance of neurotransmitters in the brain. Neurotransmitters are the nodes which relay signals in the brain, and increased neurotransmitter performance is strongly linked with a general increase in cognitive function.

Beware Of Imposters

L-carnitine comes in several varieties. Though the acetyl L-carnitine variety is considered the most effective, you may come across others in your research.

L-Carnitine L-Tartrate

Similar to acetyl L-Carnitine, this form is often used as a sports supplement. It’s been suggested to help with exercise performance and sports recovery. It also has an efficient rate of absorption.

Glycine-Propionyl-L-Carnitine

This form of L-Carnitine requires a propionyl ester as well as a glycine compound. Typically used more in the medical field, glycine-propionyl-L-carnitine is effective for improving circulation and alleviating high blood pressure.

D-Carnitine

An inactive form of carnitine. You’ll want to avoid this type when supplementing, as it can interfere with the absorption of acetyl L-carnitine.

While each of these has their own uses, none is widely considered superior to acetyl L-carnitine. However, if your own research tells you that one of these might be more suitable to your own personal goals, there’s certainly no harm in that.

How Much Acetyl L-Carnitine Do I Need?

In order to enjoy the benefits associated with acetyl L-carnitine, you must consume enough iron and vitamin C. Here are the recommended daily intakes for all three:

  • Acetyl L-Carnitine: 1000 mg to 2500 mg
  • Iron: 20 mg (men) / 17 mg (women)
  • Vitamin C: 90 mg (men) / 75 mg (women)
