Acetyl-L-carnitine pros 

. Fat Burner 

If you are exercising and dieting, but you don’t get the result you were looking for, its time to consider supplementing with acetyl-L-carnitine  Because not only it gives you fat burning benefit, it’ll also fuel your muscles to get through that heavy lifting gym session.

. Boosts The Brain

Seriously who doesn’t want to burn fat and get smarter at the same time? The good news is Acetyl passes into the brain through blood-brain walls and enhances your brain performance.

. Fights fatigue and mental fog

According to NCBI Acetyl L-carnitine  AKA (ALC) is helping elderly patients with fatigue and mental fog.

. Boosts Your Testosterone level

Another survey shows, that men who take Acetyl L-carnitine especially 90 minutes before their heavy lifting sessions tended to have more testosterone receptors in their muscles. therefore they can gain more muscle mass in a  faster fashion.

. Helping for processing of the glucose 

It’s been shown Acetyl L Carnitine [ALCAR] is helping with insulin insensitivity to lower the blood sugar level. That’ll help people with the insulin resistance for better processing glucose in their mitochondria.

. Fights ADHD

Again because of its nootropic properties it could help ADHD patients to overcome their unfocused brain, meanwhile increasing their mental clarity. 

. Cons

While there are tons of benefits to Acetyl L-carnitine to at least give it a try, in some people have shown side effects like nausea, upset stomach, and headaches, etc.. So it’s best if you start with lower dosages 1g/day and study your body response.

With all been said I was off the supplements for the last two months, (sometimes I do that to make sure if it’s still a right fit). I don’t eat as much and started to run 3/weekly each session more than 10 miles.  I noticed that I lose weight faster when I am taking Acetyl L-carnitine. So moral of the story do your own research before start taking any form of supplements, but trust me this is a good one.
