Compared with all other fat burning products on the market, L-Carnitine has been much more effective for me than almost all others. There is a lot of debate surrounding this product, and whether it works as a fat burning agent, but I am a firm believer!
As being a proposed fat-burner and performance enhancing supplement, L-carnitine has a long history and plenty of lovers.
L-carnitine first broke on to the supplement scene as a fat burner back in the 1980s, but quickly lost is overwhelming hype due to stimulant-based fat burners and fat-burners which offered quicker results.
Today, people still argue against the need for l-carnitine supplementation, since stimulant-based fat burners show bigger effects in less time.
However, carnitine works in a much more natural way for your body!
One of the main reasons I am a firm believer in the benefits of l-carnitine is because it works extremely well with intermittent fasting, and fasted cardio.
Both principles are heavily debated as well, but they are mainstays in my routine.
Coupled with intermittent fasting, l-carnitine can be the perfect supplement to help you to burn off stubborn body fat, and build the most aesthetic body of your life!
For those of you who are wondering how this non-stimulant supplement can aid you in burning fat, I will discuss the science behind L-carnitine and my opinion on how to use it effectively!
Keep reading to learn more about why to use L-Carnitine supplements, and how to choose the best carnitine supplement!
What are L Carnitine Supplements?
L-carnitine is often classified as being an amino acid, while technically it really isn’t.
It is widely considered as a vitamin-like, and amino acid-like compound, which is closely related to the B-vitamins. When studies were first carried out on carnitine back in the 1905s, it was referred to as Vitamin BT.
You can also get this nutrient from plant sources such as soybeans and avocado, but the best source as a rule is meat (the redder the better).
In our diets, L-carnitine comes mainly from meat and other animal products. Beef and bison are especially high in carnitine.
Furthermore, L-Carnitine supplements are now widely available for purchase throughout the world, and you can easily purchase high quality L-Carnitine online.
For the effectiveness of this product, it is well worth the money! Generally, there are two forms of Carnitine.
The latter is the one that is biologically active and found in nature.
You’ll see it listed on labels as Acetyl L-carnitine, L-carnitine L-tartrate, or Propionyl L-carnitine. These compounds are very similar, and equally effective.
On the other hand, the D form is biologically inactive, and is not sold as a supplement.
If you’re going to purchase carnitine for fat loss, make sure you buy a high-quality Acetyl L-Carnitine!
Pros and Cons of Acetyl L Carnitine Supplements
While L-carnitine is produced naturally in the liver and kidneys from the sulphur containing amino acids lysine, and methionine, it is stored elsewhere in the body.
L-carnitine is primarily stored in the muscles (heart inclusive), the brain, and even in sperm.
If you are thinking about purchasing carnitine for supplementation, the important attribute that you care about is that carnitine plays a significant role in the transfer of fatty acids to the mitochondria.
Research has shown that taking carnitine every day increases the blood muscular level, thereby enhancing fat metabolism, and subsequently better exercise performance. In my opinion, you feel this effect very quickly.
Personally, I use carnitine before basketball practices and games, along with my additional strength and conditioning.
It honestly plays a key role in helping your body’s cellular system feel energized and able to perform!
Regular supplementation with carnitine helps the body to spare glycogen usage, thereby utilizing more body fat in the process. This is the reason that I feel it is best used before fasted cardio!
Fasted cardio itself is a way of transferring your bodies fat stores in to energy.
In my opinion, l-carnitine accelerates this process as well! L-carnitine’s role as a bonafide fat burner is well documented.
Along with being a pure fat burner, it can also help you limit fat gains and make a cleaner bulk during bulking periods.
Furthermore, it can also help you transport fat deposits present in your cellular furnaces, to get burned as energy during exercise.
Research also shows that despite the presence of an extra 640 calories of fast-digesting carbohydrates in the daily diets of a group of athletes taking carnitine, no additional body fat was gained.
In this same study, a similar group intaking the same amount of carbohydrates, without carnitine, gained over 5 pounds of body fat!
Now that is an impressive difference!
The performance benefits of L carnitine are not only its ability to increase fat burning and decrease glycogen use, it’s also its ability to enhance blood flow to the muscles.
Although L-Carnitine does have an impressive list of potential benefits, there are also a few side-effects you need to be aware of.
Most of these side-effects only happen at extremely high dosages though. From experience, do not exceed the recommended daily amount of carnitine.
Twice in my past I have “over-dosed” on carnitine, and it was not pretty.
Nothing serious happened, but the stomach issues are not fun. L-carnitine can cause nausea, vomiting, diarrhea, and abdominal cramps when high doses are taken.
Extremely rare occurring side effects include muscle weakness in uremic patients, and seizures in individuals with seizure disorders.
If you are looking to purchase a fat burner, buying L-Carnitine is a healthy and wise choice!

Acetyl L-Carnitine and Intermittent Fasting
As I said before, to me, the benefits of L carnitine are most shown when used prior to fasted-training.
Fasted training doesn’t (and probably shouldn’t) consist of any form of intense exercise, but is better done as a leisurely walk or bike ride.
The greatest results I have ever had in my aesthetic appearance is when I was dedicated to moderately intense fasted training, while using a perfect combination of supplements (L-carnitine, BCAAs, and caffeine).
If you search about the benefits of fasted cardio online, you will find a very wide array of both positive and negative answers.
However, from my personal experience and years of using this in my routine, I can tell you it honestly works!
One of the lesser known processes of the human body is called “cell autophagy.”
Essentially, this is when your body eats its own dead cells, cleaning your body from the inside out.
This becomes an incredible tool for anyone who is looking to burn fat directly, and not risk burning muscle tissue. Fasting, and training while in a fasted state, is the absolute best way to maximize this effect.
Although true intermittent fasting would involve not eating anything at all for a period of around 10-16 hours, fasted training can be accomplished with the consumption of L-carnitine, BCAAs, and caffeine.
All three of these are vitally important compounds to add to your fasted training!
Without them you certainly will have some positive results (in my opinion), but not nearly as great as you would otherwise.
I’ll explain the reasons for this.
The BCAAs provide a buffer around your muscles directly, preventing catabolism.
If you do not use BCAAs before your fasted training, there is a chance that some of your muscle are withered away. This won’t be an intensely huge effect, but it certainly is not what we are trying to accomplish.
The caffeine helps to mobilize fat away from your body, allowing your efforts to actually burn fat. It is possible to mobilize and burn fat without taking caffeine, but unless you are doing DIY fat freezing, it is more difficult.
Be aware of in taking too much caffeine, as that can drain your adrenal system and hike your cortisol to unnatural levels. Moderate amounts of caffeine such as 1 cup of coffee work best!
Lastly, as we have stated above, L-carnitine transfers the mobilized fat out of your body.
Together, this is something I would consider to be a wonder-stack!
High-stimulant based fat burners can have incredible effects on your body and appearance quickly, but they come with huge risks and side effects.
Cell autophagy is one of the amazing natural process of our human body, and if you understand how to maximize its effects; you will quickly be on your way to your best body ever!
Taking advantage of this process also leave your body feeling lighter and more active, allowing you to train hard, lose weight fast, and avoid that sluggish feeling we all hate!
Necessary Dosage for L Carnitine Supplements
As little as 1 gram of L-carnitine can be highly effective, and taking 2-3 grams per dose is generally your best bet for maximum benefit.
When I do my fasted training, I normally will take 1-1.5g of l-carnitine, since in a fasted state you do not need as much to have the required effects.
If this is going to be your first time taking L-Carnitine, I suggest starting with a 500mg dosage.
L-Carnitine will increase the temperature inside your body, and it is best to work your way up in dosage slowly!
I highly recommend combining carnitine with caffeine, because you will feel much more energized than either alone.
I cannot exactly say why this is, but try it and you’ll see!
The Best L Carnitine Supplement (In My Opinion)
Many people have written l-carnitine off as an effective fat burner since there are so many fat burners which promise quick results.
L-carnitine works for your body in a much different manner, and is exceptional for your health on a cellular level. Be cautious when you first begin to supplement with l-carnitine, but don’t be afraid to purchase this supplement for powerful fat burning!!
If you want to find a perfect supplement for “all in one” fat burning to be used with fasted training, check out RSP Nutrition AminoLean!
This is seriously my favorite product on the market right now, since it combines amino acids, caffeine (from green tea), and L-carnitine! I am yet to find a more perfect product to be used before fasted training, or training in general.
Often, I will just use a combination of bulk BCAAs, coffee with coconut oil (aka Bulletproof Coffee), and pure L-Carnitine; but AminoLean is even more convenient!
If you want to try this product, there are many various sources you can purchase it from online.
One of my favorites is NOW L-Carnitine on Amazon, which is very cheap for the given amount.
