We investigated the impacts of acetyl L-carnitine (ALC) on chronic fatigue in elderly patients, examining 96 individuals aged 70 and above. The study utilized fatigue scales to assess changes after treatment.
Results indicated that ALC significantly reduced both physical and mental fatigue while improving cognitive function and overall physical status. Participants reported a notable decrease in muscle pain and sleep disorders, alongside improvements in fatigue severity.
Overall, ALC shows promise as a treatment option for alleviating chronic fatigue in older adults.

We explored the impact of acetyl L-carnitine, propionyl L-carnitine, and their combination on chronic fatigue syndrome (CFS) in a group of 90 patients over 24 weeks.
The results indicated significant improvements in fatigue and attention concentration, with acetyl L-carnitine particularly benefiting mental fatigue and propionyl L-carnitine focused on general fatigue.
However, those receiving both treatments showed less improvement. It’s also worth noting that many patients experienced a return of fatigue after treatment ended.

We analyzed a study that compared duloxetine and acetyl L-carnitine in treating female patients with fibromyalgia syndrome (FMS).
Over 12 weeks, the 65 participants took either duloxetine or acetyl L-carnitine, with evaluations conducted to assess their symptoms.
While both treatments improved overall well-being and pain levels, only duloxetine showed significant effects on anxiety and psychological aspects of quality of life.
Thus, acetyl L-carnitine shows promise but may not offer significant benefits for anxiety improvement in FMS patients.

Sustained energy boost

Having struggled with chronic fatigue syndrome for over a decade, I have tried numerous solutions for energy, but they all overstimulated my adrenals and left me feeling worse. Finally, I've found something that helps me gently maintain a decent level of energy.

Increased physical endurance
3 people found this helpful
Battery Energizer is always with me! I highly recommend it for enhancing physical endurance. I take 2 capsules in the morning. Although the instructions allow for up to 4 tablets daily, I found that 2 gives me so much energy that I feel I can do anything! I no longer feel fatigued, even in the evenings. If you wish to keep pace, buy and take this—you won't regret it!

ALCAR improves MS fatigue tolerance
We conducted a clinical trial to see how acetyl L-carnitine (ALCAR) stacks up against amantadine for treating fatigue in multiple sclerosis patients. In this study, 36 patients were given either ALCAR or amantadine for three months and then switched to the other treatment after a washout period.
We found that ALCAR showed greater effectiveness in reducing fatigue, as measured by the Fatigue Severity Scale. However, it did not show significant benefits in other areas like depression or social experiences. Overall, ALCAR was better tolerated than amantadine, making it a promising option for managing fatigue.

Beneficial for CFS
1 people found this helpful
This is a good product from Now Foods. Acetyl L-Carnitine has positively impacted my chronic fatigue syndrome. My research on this was invaluable, and it's easy to swallow, so I'll definitely buy it again. CFS patients often have reduced levels of L-Carnitine, making this a valuable supplement.

Improved health
Our family's intake of l-carnitine started with a doctor’s prescription to improve spermogram indices, requiring daily doses. The dosage is convenient and adjusts easily by capsule count. Taking it with meals twice daily, our overall health improved, and I experienced less fatigue during winter and spring.
