Acetyl-l carnitine for mood disorders
A double-blind, randomised, controlled clinical trial of acetyl-L-carnitine vs. amisulpride in the treatment of dysthymia.
Eur Neuropsychopharmacol. 2006 May;16(4):281-7. Department of Psychiatry, School of Medicine, Vita-Salute University San Raffaele, Milan, Italy.
Researchers evaluated the effect of acetyl-L-carnitine ( ALCAR ) vs. amisulpride measured by total Hamilton Depression Rating Scale score in patients with pure dysthymia. Two hundred and four patients were randomised and treated with ALCAR 500 mg twice a day or amisulpride 50 mg u.i.d. in a double-blind study, for 12 weeks. RESULTS: A solid improvement was observed in both treatment groups throughout the study. The results did not disclose statistically significant differences between treatments. The greater tolerability of ALCAR is of clinical relevance considering the chronicity of dysthymia, which often requires prolonged treatment.

Acetyl l-carnitine for infertility
Researchers at the
Polytechnic University of Marche, in Italy had an inkling that supplements could make a difference. They evaluated sixty infertile men between the ages of 20 and 40 who had poor sperm motility or movement. They gave these men the nutrients carnitine, acetyl l-carnitine, or a combination. The results showed that the combination of carnitine and acetyl l-carnitine had the best outcome with improvement noted in sperm motility and velocity. The antioxidant capacity of the sperm fluid also increased.
   It would seem reasonable for men who have undergone a medical evaluation for infertility and have not had success with the standard medical approach to try a combination of these two nutrients, particularly if analysis shows their sperm do not swim well or are slow movers. The ideal dosage is difficult to know, but a cautious approach would be to alternate taking 200 to 300 mg of acetyl l-carnitine one day and 200 to 300 mg of carnitine the following day. The dosage can be increased after a month or two if the results are not adequate. Higher doses could lead to overstimulation, restlessness, and insomnia. 

Acetyl-l-carnitine side effect
Side effects of acetyl-l-carnitine include overstimulation at dosages greater than 500 mg. Nausea is another acetyl-l-carnitine side effect.

How often to take an acetyl-carnitine supplement
Acetyl-l-Carnitine 300 mg is a potent mind booster and antioxidant. Most people find one capsule is the right dose while some people may find the occasional use of 2 capsules helpful. Acetylcarnitine increases alertness and focus. It would be best not to take a capsule with other brain boosting supplements due to possible overstimulation. One option is to alternate the use of acetylcarnitine one day with Mind Power Rx the next day, or alternate with other brain supplements such as DMAE, choline, ginkgo, etc. Doses above 500 mg may, in some people, lead to overstimulation, insomnia, and nausea. For long term use one capsule 3 times a week with a week off each month is a good option. Acetylcarnitne can be taken with small doses of other supplements such as vitamins E and C, and it can be used together with fish oils. Many products on the market have acetylcarnitine together with alpha lipoic acid and are promoted for antiaging purposes. Be careful using high amounts of these combinations since they can keep you awake at night, and shallow sleep is certainly not helpful for longevity purposes. We would not recommend taking more than 10 to 30 mg of R lipoic acid or 20 to 60 mg of regular alpha lipoic acid when combined with 300 mg of acetylcarnitine.

Acetyl-l-carnitine study
The association of acetyl-l-carnitine and nicotinamide remits the experimental diabetes in mice by multiple low-dose streptozotocin.
Pancreas. 2006 Nov;33(4):403-11. Centro de Investigaciones Endocrinologicas (CEDIE-CONICET), Htal. de Ninos R. Gutierrez, Buenos Aires, Argentina.
We studied the effect of acetyl-l-carnitine plus nicotinamide on murine diabetes mellitus induced by multiple low doses of streptozotocin. Male C57BL/6J inbred mice were injected intraperitoneally with citrate buffer or streptozotocin (40 mg/kg) for 5 consecutive days, followed by injections of saline solution or acetyl-l-carnitine plus nicotinamide (50 + 25 mg/kg) from days 6 to 110. Four groups were studied: normal control mice (C), treated normal control mice (TC), diabetic mice (D), and treated diabetic mice (TD). The treatment with acetyl-l-carnitine plus nicotinamide induced remission of autoimmune type 1 diabetes in mice produced by multiple low doses of streptozotocin.

   A.
Acetyl-l-Carnitine 300 mg is a potent mind booster and antioxidant. Most people find one capsule is the right dose while some people may find the occasional use of 2 capsules helpful. Acetylcarnitine increases alertness and focus. It would be best not to take a capsule with other brain boosting supplements due to possible overstimulation.

Many products on the market have acetylcarnitine together with alpha lipoic acid and are promoted for antiaging purposes. Be careful using high amounts of these combinations since they can keep you awake at night, and shallow sleep is certainly not helpful for longevity purposes. I would not recommend taking more than 10 to 30 mg of R lipoic acid or 20 to 60 mg of regular alpha lipoic acid when combined with 300 mg of acetylcarnitine. There is no human evidence that the combination of these two nutrients is better than either alone. Even if the combination is preferable, we have no idea of the ideal dosage, and it could be vastly different between different people. Both acetyl-l-carnitine and alpha lipoic acid can be taken with food to reduce nausea, but if one wishes to feel the mental stimulating effects more clearly, they can be taken on an empty stomach.

Q. Does acetyl-l-carnitine help Impotence?
