Taken by individuals looking to enhance their physique and by those seeking weight loss, there is limited evidence supporting the effectiveness of this supplement for these purposes.
However, despite the lack of research supporting these claims, there is substantial evidence that acetyl l carnitine (ALC) is highly beneficial in enhancing cognitive function and treating nervous system disorders.
Approved in Europe for treating neurological conditions in the 1980s, ALC became available to Americans legally in 1994.
Today, many people use this supplement not only to boost cognitive health but also to combat the effects of aging. Here's how this simple and safe nutrient can benefit you. . .
Initially, there was little interest in ALC in the US until Dr. Bruce Ames, a distinguished professor of biochemistry and molecular biology at the University of California, highlighted its potential benefits.
Dr. Ames, focusing on strategies to reverse aging effects, particularly studied mitochondria—the energy-producing units within cells known as "cellular batteries."
As we age, mitochondrial function declines, leading to degenerative diseases and cognitive deterioration. Maintaining youthful mitochondria can help prevent illnesses and extend lifespan.
Dr. Ames conducted experiments where old rats were given acetyl l-carnitine, resulting in the restoration of three out of four age-related mitochondrial functions to levels similar to those in young rats.
At 87 years old, Dr. Ames continues his work, crediting daily intake of ALC, along with other nutrients, for keeping his mind sharp and counteracting aging effects.
ALC provides protection and support for brain health through various mechanisms:
Several human studies support the notion that acetyl l-carnitine improves energy levels and cognitive function. While not FDA-certified evidence, these studies are compelling until further research is conducted.
In a study involving 30 patients with chronic fatigue, ALC supplementation for six months reduced mental fatigue, improved focus, and concentration. Post-supplementation cessation, more than half of the patients reported worsened fatigue within two weeks.
Among 96 individuals aged 71 to 88 experiencing fatigue, ALC intake reduced physical and mental fatigue and enhanced cognitive performance.
In a study with 481 older adults exhibiting mild cognitive impairment, significant improvement in cognition and memory was observed after 90 days of supplementation.
60 participants over 65 years with mild cognitive impairment were given either ALC or a placebo for three months. Notably, only the ALC group showed enhancements in behavior, memory, attention, and verbal fluency.
An analysis of 21 trials comparing ALC with a placebo in individuals with mild cognitive impairment or mild Alzheimer's disease revealed significant efficacy in the group taking the active supplement.
While ALC may be promoted for unproven claims like weight loss, there is sufficient evidence supporting its role in brain protection, cognitive preservation, and delaying aging effects.
While not everyone may aspire to work into their late 80s like Professor Ames, acetyl l-carnitine is a supplement that may enhance the chances of doing so if chosen.
