Best L-Carnitine Supplements (2022)

Best L-Carnitine Supplements

L-carnitine supplements do not directly promote weight loss as it is often marketed. Still, there is some scientific evidence to suggest that there are a few benefits of l carnitine supplements.

Using l-carnitine supplements for weight loss became popular in the 1980s but quickly lost its hype due to the rise of stimulant-based fat burners and fat-burners offering quicker results.

L-Carnitine is an endogenous chemical that helps the body turn stored fat into useable energy, and it is produced through a reaction of l-lysine and l-methionine.

Dietary sources of l-carnitine include beef, bison, and lamb, along with various other animal and plant sources.

Carnitine can come in two forms:

  • D-Carnitine
  • L-Carnitine.

L-Carnitine is the carnitine supplement form that is biologically active and found in nature.

Other names for carnitine supplements include:

  • Acetyl L-carnitine
  • L-carnitine L-tartrate
  • Propionyl L-carnitine.

Benefits of L-Carnitine Supplements

In the body, carnitine plays a role in fatty acid transport, which is why many people assume you should use L-carnitine supplements for weight loss. However, L-carnitine supplements don’t necessarily produce additional fatty acid transport, and more does not equal better.

However, there are other benefits of L-carnitine supplements.

Improved Physical Performance

Research has shown that taking carnitine supplements enhances fatty acid metabolism and improves exercise performance.

Additionally, research indicates l-carnitine may improve exercise performance by controlling blood lactate and oxidative stress responses to resistance training.

Using an l-carnitine supplement can help you lose weight because it can help you have longer and more intense workouts.

If you are doing weight training or other forms of exercise frequently, an l-carnitine supplement may help improve the results of your efforts.

The benefits of l-carnitine are one of the main reasons I am a huge fan of the RSP Amino Lean supplement.

Combined with other beneficial ingredients like caffeine, amino acids, green tea extract, and green coffee bean extract, taking l-carnitine in RSP Amino Lean helps me have outstanding workouts and get sustained results.

Reduced Muscle Soreness and Exercise Fatigue

Along with promoting exercise performance, research indicates that l-carnitine supplements can reduce muscle injury, markers of cellular damage, and free radical formation that normally accompany muscle soreness.

Additionally, research indicates that they can reduce muscle soreness and markers of muscle damage.

Can Prevent Weight Gain

Although research does not indicate L-Carnitine supplements will directly promote weight, research has demonstrated that they can prevent weight gain even when calorie intake is increased.

In one study, a 20% increase in muscle carnitine resulted in greater energy expenditure during low-intensity physical activity, increased fat oxidation, improved insulin signaling, and other benefits that negated the effects of a daily high-carbohydrate beverage that promoted 1.8 kilograms of weight gain in a control group.

Taking l-carnitine supplements may help people trying to lose weight through diet and exercise but occasionally overeat carbohydrates.

Normalized Carnitine Levels for Vegans & Vegetarians

Vegans and vegetarians who do not consume animal products and do not intake high levels of naturally occurring carnitine may receive significant benefits from carnitine supplements.

Since vegans and vegetarians have chronically low intakes of carnitine in their diets, research indicates taking a supplement is an excellent way to maintain healthy levels.

L Carnitine Supplement Reviews – The 5 Best L Carnitine Supplements

If you are interested in trying l-carnitine supplements due to the potential benefits listed above, here are some of the best l-carnitine supplements:

1.) Dr. Martin’s Nutrition L-Carnitine

If you want a product that contains nothing additionally, I believe the best l-carnitine supplement is Dr. Martin’s Nutrition because it is the cheapest product at a high production standard.

Each bottle contains 200 capsules of 1,000mg per serving, and a serving is two capsules each.

I have never used this brand, but they have strong reviews and are a reputable company.

2.) RSP Nutrition Amino Lean

I am tempted to put RSP AminoLean as the best l-carnitine supplement, but I chose a pure carnitine supplement first because many people want to know exactly how much carnitine is in their product.

However, RSP Amino Lean contains a 1.5g proprietary blend that includes l-carnitine.

As I mentioned, RSP Amino Lean also includes the natural fat burners CLA, green tea extract, caffeine, and green coffee extract.

Since it is a proprietary weight management formula, we do not know how much l-carnitine is in RSP Amino Lean. However, I have used Amino Lean for years and have had a lot of success.

If you want a supplement that can provide energy before workouts, amino acids to promote muscle recovery, and ingredients that assist with weight management, RSP Amino Lean might be the best l-carnitine supplement for you!

3.) BPI Sports CLA + Carnitine

Another combination supplement is BPI Sports CLA + Carnitine.

BPI Sports CLA + Carnitine is one of the best L Carnitine supplements because it combines carnitine with Conjugated Linoleic Acid (CLA), another of my favorite supplements for weight management.

The downside of this product, especially compared to RSP Amino Lean, is that it is artificially flavored and a bit expensive.

However, this combination of ingredients can help promote healthy weight management.

4.) Vega Sport Vegan L-Carnitine

For those who are vegan or vegetarian, Vega Sport Vegan L-Carnitine is a certified vegan L-Carnitine supplement.

Vega Sport Vegan L-Carnitine is more expensive than the other options listed above, but the main benefit is that it is 100% vegan.

Although it costs more, it is one of the only vegan l-carnitine supplements.

5.) Now Foods L Carnitine

Now Foods L Carnitine supplement costs only $0.27 per serving, which is very affordable.

Also, Now Foods is a very reputable brand, and you can nearly always trust its products. I have used NOW Foods L-Carnitine in the past, but since beginning to use RSP Amino Lean, I have not used it as often.

Best Time to Take L-Carnitine Supplements

Studies conducted on L-carnitine benefits have indicated that L-carnitine does not need to be taken at a specific time. Although you can take your l-carnitine supplements before exercising, taking them at a specific time is not necessarily important.

Instead, you should focus on taking the proper dosage of L-Carnitine daily.

Best L Carnitine Dosage

The best l carnitine dosage is not fully known as research studies have used various carnitine dosages.

If this is your first time taking an l-carnitine supplement, I suggest starting with a 500mg dosage daily and increasing your intake over time.

A maximum of two grams of carnitine supplements per day can usually be tolerated and produce a benefit.

Side Effects of L Carnitine Supplements

Carnitine supplements are generally safe and are FDA approved for treating carnitine deficiency.

However, at doses of approximately 3 grams per day, carnitine supplements can cause nausea, vomiting, abdominal cramps, diarrhea, and a “fishy” body odor.

If you are a person who is active and exercising frequently, l-carnitine supplements might help improve your physical performance and assist with healthy weight management.

Since L-carnitine has demonstrated an ability to improve exercise capacity and reduce fatigue associated

L-carnitine supplements do not directly promote weight loss, but they can play a role in supporting healthy weight management and improving physical performance.
