Acetyl-L-Carnitine shows effectiveness
We investigated how acetyl-L-carnitine (ALC) might help patients suffering from chemotherapy-induced peripheral neuropathy (CIPN). In a well-structured study involving 239 patients, we divided participants into two groups—one receiving ALC and the other a placebo.

After eight weeks, a significant number of ALC patients showed improvement in their neuropathy symptoms compared to those receiving the placebo.

Additionally, ALC treatment not only reduced neuropathy but also eased cancer-related fatigue without notable safety concerns. Our findings suggest ALC can be an effective option in treating CIPN.

We examined the effects of Acetyl-L-Carnitine (ALCAR) on nerve regeneration in animal studies, particularly focusing on peripheral neuropathies caused by injuries.

This systematic review and meta-analysis considered various studies that administered ALCAR to rats with sciatic nerve injuries.

While ALCAR showed promise in improving pain tolerance and reducing damage, the specific mechanisms behind its benefits remain unclear and warrant further investigation.

We examined the effectiveness of acetyl-L-carnitine (ALC) in treating painful peripheral neuropathy. Our analysis included 14 trials featuring patients suffering from this condition, notably those with diabetes or HIV-related neuropathy.

A meta-analysis demonstrated that ALC led to a significant 20.2% reduction in pain compared to a placebo. Additionally, ALC showed promising results regarding nerve function improvement and regeneration, along with a favorable safety profile.

Although findings are encouraging, further research is needed to fine-tune dosage and treatment duration.

Improved sensation

Great product! My acupuncturist suggested 1500 mg per day for neuropathy in my feet and legs. On the first day, I immediately felt sensation in my feet that I hadn’t experienced for a long time. I also have more energy and can walk further now. I will continue using this form of ALC alongside Alpha Lipoic Acid and other supplements.

Excellent! Five years ago, Acetyl-L-Carnitine was recommended for my Crohn's disease and it has tremendously helped in managing bowel symptoms. After initially trying it for 30 days, I noticed a difference when I ran out within four days. Now, I keep an extra bottle on hand. It also helps alleviate the neuropathy pain in my left foot.

ALCAR enhances nerve regeneration
We explored how acetyl-l-carnitine (ALCAR) treatment could boost nerve regeneration when combined with decellularized nerve allografts and adipose-derived stromal cells (ASCs). In our study with seventy rats, we used various groups to assess outcomes after bridging a 10-mm sciatic nerve defect.

ALCAR notably supported the survival of ASCs and increased neurotrophic factor expression in the grafts. Overall, results showed that ALCAR enhanced the regenerative effects of ASCs and acellular grafts, achieving results comparable to traditional nerve autografts.

Acetyl L-Carnitine improves CTS symptoms
We investigated how acetyl L-carnitine (LAC) influences neuroprotection, pain relief, and hand function in patients suffering from carpal tunnel syndrome (CTS). In this blind study featuring 82 patients over four months, we noted significant improvements in nerve conduction and sensory abilities after LAC treatment.

Pain levels also decreased markedly, especially in pressure-related discomfort. These findings suggest that LAC could be a beneficial therapeutic option for managing symptoms in mild to moderate CTS cases, thanks to its neuroprotective and anti-nociceptive effects.

Exploring drug efficacy for CAN
We examined the effectiveness of various drug treatments for cardiovascular autonomic neuropathy (CAN) in diabetic patients. Our study included a comprehensive review of randomized controlled trials, focusing on treatments that impact heart rate and blood pressure.

We found that several options, including angiotensin-converting enzyme inhibitors and acetyl L-carnitine, showed significant improvements in autonomic function. However, vitamin B12 alone did not demonstrate efficacy. Our findings suggest that while some treatments are beneficial, others like vitamin B12 monotherapy may not be recommended.

Reduced neuropathy symptoms
Helping with peripheral neuropathy... I began taking Acetyl-L-Carnitine, ALA, Benfotiamine, D3 & K2, B12 and B6 six weeks ago, and I've noticed a reduction in the mild neuropathy in my toes. I've combined this with nerve stretching and high-intensity interval training, making it difficult to determine which part of the regimen is effective. As always with vitamins, your results may differ!

Effective neuropathy support
I previously used Acetyl-L-Carnitine with alpha-lipoic acid for neuropathy, which was excellent support. NOW, the A-L-Carnitine capsules are of good size and quality.

Dietary supplements and neuropathy findings
We analyzed the effectiveness of dietary interventions and supplements in managing chronic neuropathic pain. Following strict research guidelines, we reviewed 40 studies focusing on conditions like chemotherapy-induced peripheral neuropathy and diabetic peripheral neuropathy.

While some treatments showed potential, acetyl L-carnitine appeared ineffective or possibly harmful. We couldn't recommend its use for pain management. However, alpha-lipoic acid and vitamin D were found to be beneficial for diabetic neuropathy. More research is needed to clarify these results.
7
ALC and MC show equivalent efficacy
We conducted a robust study comparing acetyl-L-carnitine (ALC) and methylcobalamin (MC) for treating diabetic peripheral neuropathy.

Over 24 weeks, we enrolled over 230 diabetic patients, with half receiving ALC and the other half MC.

Both treatments significantly reduced symptoms of neuropathy without notable side effects, yet neither showed superiority over the other.

This suggests that ALC is as effective as MC for managing neuropathy symptoms and improving nerve function.
