Acetyl L-Carnitine

Effects on Brain Function
L-carnitine may benefit brain function.
Some animal studies suggest that the acetyl form, acetyl-L-carnitine (ALCAR), may help prevent age-related mental decline and improve markers of learning.
Human studies indicate that taking acetyl-L-carnitine daily helps reverse the decline in brain function associated with Alzheimer’s and other brain diseases.
This form exhibited similar benefits for general brain function in older adults who did not have Alzheimer’s or other brain conditions.
In specific cases, this form may even protect your brain from cell damage.
In a 90-day study, people with alcohol addictions who took 2 grams of acetyl-L-carnitine per day experienced significant improvements in all measures of brain function.
More research is needed on long-term benefits for healthy individuals.
