About Acetyl L-Carnitine?

Acetyl L-Carnitine is actually a form of a derivative of a naturally occurring amino acid within the body, known as carnitine. Carnitine plays an essential role in fat metabolism as it basically functions as a transporter for fatty acids within the body. This compound actually transports fatty acids into the mitochondria of cells, which is where cells get their energy. Within the body, it is primarily produced within the kidneys and within the liver. Carnitine is produced naturally by the body from amino acids such as methionine and lysine. Acetyl L-Carnitine supplements are ideal however, as they ensure the body has a constant supply of this highly beneficial ingredient.

How does it work?

Acetyl L-Carnitine basically helps the body to metabolize body fat as you exercise and exert yourself physically. It is able to do this by lessening the passage of long chain fatty acids through the walls of the mitochondria within the cells. During the initial stages of exercise, glycogen stores quickly diminish and so the body is forced to find an alternate source of energy, which it gets in the form of body fat. Your endurance will help determine how much fat you actually use up. Acetyl L-Carnitine however, basically helps to ensure that you burn more fat and therefore not only lose weight, but also that you have more energy in the process.

What are the main benefits of Acetyl L-Carnitine?

There are many benefits associated with this supplement, and whilst some of them we’ve already looked at, others you may be surprised to learn of. Here’s a more detailed look.

Fat Loss

Obviously the biggest benefit associated with Acetyl L-Carnitine is the fact that it helps the body to burn off body fat. It helps ease long chain fatty acid passages through mitochondrial cell walls, meaning that the cells can utilize them quicker and more efficiently. Put simply, it allows the body to burn off more body fat for energy than it would ordinarily.

Increased Energy Levels

Another great benefit of Acetyl L-Carnitine is that as it allows more fat to be utilized by the body for energy, you will have more energy than you would have had previously. Simply put, your energy will come from your stored body fat reserves, so by exercising you will be fuelling your workouts with your fat.

Enhanced Mental Focus

Remember, we’re comprised of billions of microscopic cells and this includes our brains. Acetyl L-Carnitine supplementation can therefore enhance brain focus and health so you will think clearer, concentrate more, and will just generally enjoy more mental health benefits.

Increased Testosterone Production

For men with low testosterone levels, studies have also found that Acetyl L-Carnitine could help to boost natural testosterone levels, with levels thought to begin increasing in a matter of weeks with regular supplementation.

Increased Muscle Mass

There are two ways in which this supplement is able to promote increases in lean muscle mass and definition. The first way is simply down to the fact that, as the supplement ramps up your metabolism, the more energy you have, the more efficient your workouts in the gym will become, and therefore the more muscle you will be able to build. The second reason however, is down to the fact that it helps increase testosterone levels. Testosterone is the dominant male sexual health hormone that plays a key role in a number of processes, including muscle growth and repair.

So, to summarize, the main benefits are:

  • Increased fat loss
  • More energy
  • Increased muscle mass
  • Improved mental health and function
  • Increased testosterone production
  • Reduced mental health conditions such as stress, depression, and anxiety.

How and when should you take it?

The supplement should be taken orally, and in terms of dosage, it all depends on what you’re hoping to achieve. For mental health, experts recommend 1500 – 4000 mg per day, split into two or three dosages throughout the day. Generally speaking however, for weight loss/maintenance, experts recommend 500 – 1500mg per day.

Health Canada Recommended Dose (capsules): 3 - 4 Capsule(s) 1 - 2 time(s) per day.
Health Canada Recommended Dose (powder): Adults: 2 - 4 Scoop(s) 1 time(s) per day.

L-Carnitine VS Acetyl L-Carnitine

People may find themselves confused by L-Carnitine and Acetyl L-Carnitine, wondering what the main differences are. Put simply, if you ever see the two together on store shelves, and wonder what the difference between the two is, the short answer is that they both come from the same amino acid, but happen to function differently. L-Carnitine provides the fat loss benefits, whereas the Acetyl L-Carnitine provides those same benefits, with the added bonus of being processed, so that it penetrates the blood-brain barrier quicker, and therefore also provides mental health benefits.

What can you stack it with?

In reality, you can stack Acetyl L-Carnitine with a number of other supplements, including potent fat burners. The most valuable thing to take the supplement with however, is a form of carbohydrate as this will ensure the supplement makes its way into the muscles due to the insulin spike. Because of this, Dextrose works very well.

Great if the powder form is not feasible
Sheldon T. on 20/07/2016
Bought the powder and capsules, the powder is preferred (a bit tarty) from a price perspective, but the capsules are great if you are taking them at work or are simply too lazy to scoop the powder into water and stir (we've all been there).

Best price around and well worth the money!

I have been taking ALCAR for a few months now. When I first started taking this supplement I didn't know what to expect. I was taking it in a stack with high dose vitamin B5 and B3 for acne problems that I developed while taking testosterone and other things. It does seem to keep the acne at bay witch is good news. What I did not expect to happen was the fat that I started losing in the most stubborn places. I was also taking green tea extract and caffeine with ALCAR. Another thing that I noticed was that my moods were improving. At first I didn't really notice it but I continued to have good moods so it must have been the supplement. I recommend taking green tea extract and caffeine with this supplement. You will get much better results.

Since my move to Canada i have had problems finding a good online supplement company, until i came across Canadian These L-carnitine caps have to be the most potent supplement of its kind,supplementing with this product along with Canadian proteins CLA has helped me start to get to 10% BF. If you are trying to get lean or cutting for contests i would highly recomend this product.

The potentcy of this product is off the charts. I have been taking it for just over 6 days now and already have a leaner, tighter physique. Also I can tell my brain is functioning little clearer as well as the energy I have is phenominal as I don't take caffiene products this gives me an extra edge while in the gym and everyday life. Can't wait to see the results after a month of use. Thank you Canadian Protien for a wonderful source of Acetyl L-Carnitine.

I've started using this product with my pre-workout and notice it helping burn excess fat, particularly the hard to lose visceral fat that cardio alone wasn't doing. A definite difference. Very satisfied.

Much cheaper than capsules. Use it at 1,5 grams mixed with pre-workout or first thing in the morning with tyrosine and caffeine. Does the trick!

Rick on 13/01/2014
No way to sugarcoat this one. The stuff has a very sour taste. Like Dionne said in his review, you can get away with putting this in orange juice or some sort of citrus drink but that's about it. If you mix it with water the taste compares to slightly watered-down lemon juice. For that reason don't try and mix it with anything besides a citrus drink or water, you'll end up with something undrinkable. Just like when people complain to me about the taste of straight leucine powder in water; My question is, do you want something that tastes good or do you want results? With some supplements, you can have both.

Great product
Dionne on 15/02/2012
Great product, it really gets rid of the brain fog and keeps me alert, when I am tired in the morning, I mix a bit in my orange juice,it takes me straight through the day. the powdered form of this product is strong tasting, I wanted to see how it was, but I think I may go back to the pills. Overall great product will by again.

Best Bulk Price Around
Curtis on 27/12/2014
I use to buy Now Brand Acetyl L-Carnitine in capsules. You would get around 25g (50capsulesx500mg) for around $25 with shipping and import. Here you get around 450g for $50 with shipping+tax. That's almost 10 times the value. Also if you like very sour tasting things (I do) than the taste is for you. I take 1g (1000mg) in the morning and it's about the same potency that the NOW brand had but the value can't be beat. Plus they're one of the only retailers that ship inside Canada, everywhere else I've found ship from the US and then you get stuck with import fees unless you want the hassle of claiming it yourself. I hope they start to stock more nootropics in the future as well.

It smells like vinager but honestly regardless of smell and taste it works! Dosage 1x in the morning, pre workout, and pre meals. No more than 4 times a day and within 5 weeks I dropped 3% bf.
