We explored the relationship between circulating L-carnitine levels and the risk of neuromyelitis optica spectrum disorders (NMOSD) using data from genetic studies.
Our findings indicate that higher levels of L-carnitine may protect against NMOSD, specifically in patients who are negative for aquaporin-4 antibodies. However, there's no causal effect on the seropositive type of NMOSD.
This suggests that while L-carnitine could be a potential biomarker and therapeutic target, its effectiveness may vary depending on the patient subtype.

l-carnitine shows modest benefits
This study looked at how l-carnitine might help prevent muscle wasting in patients with Pemphigus Vulgaris, an autoimmune disease treated with glucocorticoids.
We administered l-carnitine or a placebo to 44 participants over eight weeks while measuring their muscle metabolism markers.
While the results showed some positive changes in markers like IGF-1 and myostatin, there were no significant differences between the l-carnitine and placebo groups.
Ultimately, l-carnitine appears to benefit muscle metabolism and regeneration but may not be markedly more effective than placebo.

ALC promotes remyelination, improves motor function
We explored how acetyl-L-carnitine (ALC) might aid recovery in a mouse model of multiple sclerosis, a debilitating autoimmune disorder. Using a controlled study with three groups, we assessed the effects of ALC on coordination and balance in mice subjected to cuprizone diet for 12 weeks.
Our findings showed that mice receiving ALC demonstrated improved motor skills and remyelination in the corpus callosum. ALC helped reduce harmful free radicals and boosted specific myelin-related genes, indicating its potential as a therapeutic antioxidant for myelin repair.

Enhanced energy
20 people found this helpful
This L-Carnitine is superb! After finishing my first jar, I take one tablet before training, which gives me a significant surge of energy. I can run twice as far with it, and my figure has tightened, reducing excess fat. The tablets are large and can be tough to swallow, so I plan to try a liquid version next time, but from the same brand.

Increased endurance

Awesome! I want to express my deep gratitude to the manufacturers of this drug! I felt the effect a week after starting the intake. I gained more endurance, increased energy, and improved physical capabilities, despite my muscular dystrophy. Unfortunately, the drawback is that the tablets are quite large and may cause discomfort when swallowed. However, it is convenient to divide them in half, unlike capsules. I have now ordered a lower dosage and hope the tablets will be smaller too. Overall, I am very pleased with this L-carnitine product!

Restored energy levels

Biologically active additive L-Kapnitin was recommended by my trainer for a decline in strength and energy. After taking two 1000 mg tablets for three weeks, I've experienced noticeable changes – energy has increased and fatigue has decreased. I highly recommend it!

3,3-Dimethyl-1-butanol's anti-inflammatory effects
We investigated the effects of 3,3-dimethyl-1-butanol (DMB) on collagen-induced arthritis (CIA), an autoimmune condition. Our experiments revealed that DMB significantly reduced arthritis severity by over 50%, regardless of its role in trimethylamine production, a compound linked to inflammation.
Surprisingly, DMB worked independently of the gut microbiome. We identified a new metabolite from DMB, 3,3-dimethyl-1-butyric acid (DMBut), which also showed positive effects against inflammation. Together, these findings suggest that DMB and its metabolites offer a new way to manage autoimmune arthritis through immune system modulation.

L-Carnitine aids in arthritis treatment
We explored the effects of combining L-carnitine and zinc with methotrexate (MTX) to address gastrointestinal toxicity during arthritis treatment. Conducted on Wistar rats, the study assessed various treatments for their ability to counteract MTX-related intestinal damage while enhancing anti-arthritic benefits.
We found that the combination of zinc and L-carnitine notably reduced oxidative stress and inflammation associated with MTX, activating protective signaling pathways. Overall, this approach shows promise in balancing effective arthritis management with reduced gastrointestinal side effects.

We identified that L-carnitine levels play a role in immune checkpoint inhibitor (ICI) induced myasthenia gravis (MG), a serious immune-related side effect. Through comparative genomic analysis of a thymoma patient, we discovered a genetic variant linked to this condition. Remarkably, when this patient underwent ICI treatment again with L-carnitine pretreatment, they experienced a notable response without any MG symptoms returning. This finding offers a promising glimpse into personalized treatment strategies for managing adverse effects associated with cancer therapies.

Improved physical shape

L-Carnitine is a beneficial product. I ordered it for my son. After a week of use, he started to burn fat. He takes it before training, 15 minutes prior. With L-Carnitine, he has more energy, and it's aiding his body in combating fats. He is now in near optimal physical shape, and the quality is excellent. So far, he has experienced no side effects.
