Even nowadays L-carnitine has remained one of the most popular dietary supplements, purchased with the primary objective of losing weight and getting rid of excess fat.
However, when it is the time to buy it, a question that has probably existed since time immemorial arises which is the best form of l-carnitine and which form to buy - Liquid L-Carnitine, tablets, capsules or maybe powder?
But first, let's dive into some scientific facts about L-Carnitine benefits.

2) The Top 10 L-Carnitine Supplements for 2018 Reviewed
L-Carnitine has in recent times risen in popularity as an essential nutrient and potent supplement vital for heart health, energy production and metabolism.
L-Carnitine is an amino acid that enables the human body to use the stored energy to enhance endurance in the process of recovery from vigorous exercise.
It converts fat into energy which ultimately boosts weight loss, increases strength and decreases fatigue.
However, not all these L-Carnitine sources are similar.
The name Carnitine comes from the Latin root “carnus.” It translates to flesh as it is found in meats and dairy products mostly.
This article will list nine of the best Carnitine supplements that deliver quality Carnitine in doses that are clinically proven to reap maximum benefits.
This product contains the L-Carnitine (3,000 mg/Spoonful) thrice as in the standard strength product (1,000 mg/spoonful).
NOW L-Carnitine Liquid is a popular product as it gives users all of the far-reaching benefits of L-Carnitine but in a much better form.
This liquid form is highly absorbable.
L-Carnitine is a non-essential amino acid that is vital to maintaining the body’s general health.
It does this by enabling the transfer of fatty acids groups into the mitochondrial membrane for the purpose of production of cellular energy.
Naturally occurring in red meat and other animal-source foods, this may not be enough for the body.
Adults that are omnivorous consume approximately 60-180 mg of Carnitine from their diet whereas vegans consume only 10-12 mg from a few plant based sources like asparagus.
We recommend supplementation to reach the optimal levels of this amazing amino acid.

3) L-Carnitine: The Benefits It Has To Offer
L-carnitine offers many benefits.
Some of these benefits we have already discussed above.
With that said, some of the key benefits include:
3.1) Lose Weight
3.2) Gain Muscle
3.3) Improve Bone Mass
3.4) Improve Cardiovascular Health
3.5) Kidney Treatment
3.6) Infertility Treatment
3.7) Helps Women Who Breastfeed
3.8) Diabetes Type II
3.9) Good For The Immune System
3.10) Good For Brain Function
3.11) Valproic Acid Poisoning
4) So Which Is The Better Option?
The truth is that there is no better or best option for everyone.
There is a “the most convenient” or “the cheapest for you” option.
Practically, the final effect will be the same.
The absorption is the same.
I don’t want to make this argument sound like fudge and that is why I will give you some real scientific data, which we found about a study, conducted precisely for this purpose.
5) How To Stack L-Carnitine
Stacking it is easy, but the most important thing to stack it with is carbs.
The supplement needs to be taken at a time when insulin would spike and when muscle uptake is adequate.
This is why stacking it with carbs makes sense.
Some research shows that insulin levels should be high in order for carnitine to enter the muscle cells.
The good news is that when you take the amino acid, then insulin's actions are enhanced.
The end result is more glucose being delivered into the cells, and more l-carnitine will be delivered to the cells, too.
You can get away with consuming as little as one gram of carnitine, but you should take 2-3 doses and try to take at least 30-40 grams of carbs and 20-35 grams of protein.
You don't have to, but consider taking it with a meal if you want to get the best results.
If you take l-carnitine with the right ingredients, then its fat burning properties can be enhanced, so take l-carnitine with green tea, caffeine or take it between meals.
6) When Should I Take The L-Carnitine?
By now you may be wondering when you should take it, and you should take it after working out.
Feel free to take it with a high-protein meal at any point of the day. If you stack it with fat burning ingredients, then consider taking the acetyl-L-carnitine form.
A good strategy is to take 2-3 doses of carnitine with another fat burning ingredient.
Take one dose with a post-workout meal and take the other doses without food between meals.
If you follow this strategy, then you could end up getting the best results with carnitine, so make sure you give it a try and see how it works for you.
L-carnitine is a great supplement and your body can benefit from using it, so start taking it today and start reaping the benefits.
7) A Study On L-Carnitine Forms Showed That:
The study has compared the bioavailability with a single dose of the three oral forms of L-carnitine - liquid, tablet, and chewable tablet.
As a conclusion, the study has stated that the three forms are bioequivalent, which on a pharmacokinetics language means that the substances are the same and do the same job. 
The choice of the form should be taken into account especially in terms of compactness and convenience of administration.
8) L-Carnitine Questions and Answers
8.1) What is L-carnitine used for?
L-carnitine is an essential amino acid compound, where l-carnitine is used for breaking down fats into energy.
L-carnitine delivers part of the fatty acids to the mitochondria, which is responsible for producing all the energy the body uses.
Studies prove that to use the fatty acids as energy, your body needs l-carnitine.
8.2) How much L-carnitine should I take for weight loss?
The most appropriate dosage of l carnitine for weight loss is between 1 – 3 grams of l-carnitine.
Usually, the athletes take it in a separate dosage, one dosage of l-carnitine before a workout and one dosage of l-carnitine in the evening or before bedtime.
8.3) How does carnitine work in the body?
In the body, l-carnitine works by escorting long-chain fatty acids to the cells' mitochondria, where they produce energy.
The l-carnitine can be synthesized in the body from the two essential amino acids lysine and methionine.
L-carnitine is an essential amino acid compound used for the breakdown of the fats into energy.
8.4) What is L-tartrate used for?
L-tartrate (l-carnitine-l-tartrate/LCLT) is a form of L-carnitine that is used in a lot of studies in athletes, and it is thought to have a more rapid influx into plasma following oral ingestion (which makes it useful for timing-critical situations, like pre-workout dosing).
8.5) What are the side effects of L-carnitine?
The side effects of l-carnitine are very rare.
A few studies have noted a benign adverse effect of 'odd smell,' which is said to be due to the formation of trimethylamines; it has occurred at a frequency of 4%. Some authors have stated (unpublished data) that this smell is attenuated with riboflavin supplementation.
8.6) Is L-carnitine effective for weight loss?
L-carnitine is effective for weight loss mostly when the person using the l-carnitine amino acid suffers from an l-carnitine deficiency.
Meat being the major food source of l-carnitine, vegetarians and vegans are prone to l-carnitine deficiency.
8.7) How much L-carnitine is safe to take?
L-carnitine is a very safe and well-researched supplement.
Studies have shown that taking up to 3-4 grams per day l-carnitine is safe, showing no side effects at all.
9) The Conclusion
Powdered products, for example, are much more profitable than others, but most products on the market are unflavored.
The unflavored intake of L-carnitine is really not pleasant.
Therefore, the liquid forms are always flavored.
The liquid forms, on the other hand, are not suitable for all people.
Most products don’t have a dispenser and tablespoons must be used.
You should also gauge it by the eye or drink directly from the bottle, without knowing exactly how much you should take.
These forms are not comfortable for carrying during traveling when the luggage space is limited.
While the liquid forms may not be the most comfortable, they are still the preferred choice of many.
Not because of the widespread myth of their efficiency, but most because of the some people’s problem to swallow capsules or tablets.
So when you have to choose your L-carnitine form, don’t stay away from the other forms available.
Choose the one that will be most convenient for you.
