We pride ourselves on giving our customers the tools they need to make important health decisions. So, let’s delve into the various forms of carnitine to determine which is right for you.
L-Carnitine & Acetyl-L-Carnitine
L-Carnitine helps move fatty acids across the mitochondrial membrane, supporting cellular energy metabolism. It also supports memory & cognitive health. Acetyl-L-Carnitine encourages the release of dopamine, helping it to bond to receptors, and provides antioxidant support throughout the body.

Optimized Carnitine has three advanced forms of carnitine—Acetyl-L-Carnitine, Acetyl-L-Carnitine Arginate and Propionyl-L-Carnitine (PLC)—to optimize cellular energy production for a healthy heart and brain and exercise recovery. PLC also helps support physical performance and male sexual function.

What is L-carnitine?
L-carnitine is an important nutrient that benefits your whole body, helping you produce more cellular energy while also supporting brain and heart health. This amino acid is naturally produced by the body, but production declines over time. Incorporating this cellular energy supplement into your wellness routine is a great way to retain youthful energy levels.
L-carnitine is produced by the liver and kidneys with support from vitamin C and animal proteins, including beef, chicken and fish. Taking a cellular energy supplement like L-carnitine is especially important for those on a vegan or vegetarian diet, or for those who are not able to produce enough
L-carnitine on their own.
Although L-carnitine is the most common form of this amino acid present in the body, Acetyl L-carnitine or ALCAR, also plays a vital role in your body's metabolism and helps protect your nervous system.
Does L-carnitine work?
L-carnitine supports your heart by supporting already-healthy blood pressure and promoting a healthy inflammatory response. L-carnitine has also been shown to support exercise performance by promoting exercise recovery time, muscle oxygen supply and healthy stamina.
On the other hand, Acetyl L-carnitine is a smart choice for those looking for brain boosting benefits. Studies have found that ALCAR has been shown to help support mental function while helping to sharpen learning.
