Although no treatment options have been proven to help manage 3-Methylcrotonyl-CoA carboxylase deficiency [9] proposed treatments include L-carnitine supplements, [10] glycine administration, [11] biotin supplements [4] and dietary restriction of leucine.
Free long-chain fatty acids or those that are joined with carnitine can affect the electrical properties of cardiac cells causing an irregular heart beat (arrhythmia, which can lead to cardiac arrest). Fatty acids may also build up in tissues and can damage the heart, liver, and muscles, and cause more serious complications. [citation needed]
L-Carnitine, acetyl-l-carnitine, and propionyl-l-carnitine are available in dietary supplement pills or powders, with a daily amount of 0.5 to 1 g considered to be safe. [1] [3] It is also a drug approved by the Food and Drug Administration to treat primary and certain secondary carnitine-deficiency syndromes secondary to inherited diseases. [1 ...
The disease, primary biliary cholangitis (PBC), causes inflammation of the small bile ducts in the liver and can eventually destroy them. Rival drug, Iqirvo, from Ipsen costs $11,500 per month.
As a result, these fatty acids are not converted into energy, which can lead to characteristic signs and symptoms of this disorder, such as lethargy and hypoglycemia. Levels of very long-chain fatty acids or partially degraded fatty acids may build up in tissues and can damage the heart, liver, and muscles, causing more serious complications.
The presentation of patient with SPCD can be incredibly varied, from asymptomatic to lethal cardiac manifestations. [5] Early cases were reported with liver dysfunction, muscular findings (weakness and underdevelopment), hypoketotic hypoglycemia, cardiomegaly, cardiomyopathy and marked carnitine deficiency in plasma and tissues, combined with increased excretion in urine.

Acetyl-L-carnitine, ALCAR or ALC, is an acetylated form of L-carnitine. It is naturally produced by the human body, and it is available as a dietary supplement. Acetylcarnitine is broken down in the blood by plasma esterases to carnitine which is used by the body to transport fatty acids into the mitochondria for breakdown and energy production.
In other studies, GPLC has been shown to have no effect on aerobic and anaerobic exercise performance, with results showing that up to 3 grams per day for 8 weeks in conjunction with aerobic-exercise training is ineffective for increasing muscle carnitine content and has no significant effects on aerobic- or anaerobic-exercise performance.
