L-Carnitine - A Review of Benefits, Side Effects, and Dosage

L-carnitine is a popular ingredient in several weight loss supplements. But what actually is l-carnitine? What are its benefits, side effects, if any, and what’s the right dosage when it comes to consuming l-carnitine? Have these or similar questions in mind? Then you’re at the right place as this blog has all the answers for you.

What is L-Carnitine?

Alternatively known as levocarnitine, l-carnitine is an amino acid structure that occurs naturally in your body. It’s an essential nutrient that means your body makes enough l-carnitine required for regular functioning.

However, sometimes, when your body’s ability to produce l-carnitine falls, you might have to consume l-carnitine from external sources such as supplements.

What’s the Main Role of L-Carnitine in Your Body?

L-carnitine plays a crucial role in energy production. It helps transport the long-chain fatty acids to the mitochondria of your cells, where they can be oxidized for energy production. Also, l-carnitine is important for regulating your metabolism.

What Benefits does L-Carnitine Offer?

Here are some l-carnitine benefits you can enjoy:

1. May Help Lose Weight
L-carnitine is used in several weight-loss supplements, which means it helps lose weight. An analysis that included 9 studies revealed that people who consumed l-carnitine lost 1.3 kg more weight on an average as compared to the ones who didn’t.

2. May Benefit Cognitive Function
L-carnitine, specifically acetyl l-carnitine, is known to benefit your cognitive function in numerous ways. For instance, consumption of acetyl l-carnitine daily might help reverse the damage to one’s brain caused by Alzheimer’s’ disease.

3. May Improve Heart Health
L-carnitine is also known to benefit your heart health. It plays a crucial role in driving improvement in patients suffering from heart disorders such as coronary heart disease. Also, a study noticed a reduction in heart failure & death in patients who consumed l-carnitine supplements.

4. May enhance Exercise Performance.
Several times, gym trainers recommend l-carnitine to gym-goers for better performance. It’s because l-carnitine may help:

5. Recover from exercise fatigue better.
Improve soreness after exercise.
Enhance the oxygen supply to your muscles, which again helps with recovery.
Reduce fatigue and delay discomfort, which improves stamina.

6. May Help Treat Type 2 Diabetes
L-carnitine is linked to improving symptoms of type-2 diabetes and associated complications. Also, one study revealed people suffering from type 2 diabetes who consumed anti-diabetic medication along with l-carnitine reported lower blood sugar levels as compared to placebo.

7. May Help improve PCOS and Deal with Kidney Failure.
PCOS is a hormonal condition that leads to enlarged cystic ovaries. However, consuming l-carnitine by mouth might help in ovulation and improve the chances of getting pregnant in women who don’t respond to medications such as clomiphene.

Also, the FDA has approved l-carnitine for dealing with kidney failure. However, it should be administered by IV and not by mouth. Only a medical healthcare professional can perform this procedure.

Safe Dosage and Side Effects Associated with L-Carnitine Consumption

According to experts, consuming 2 grams or less of l-carnitine is generally considered healthy.

Coming to side effects, a study revealed people who consumed even 3 grams of l-carnitine each day for 21 days reported no side effects. Also, a review conducted on l-carnitine’s safety said that consuming 2 grams each day can be considered safe. However, some mild side effects such as stomach discomfort and nausea were reported.

What are the Sources of l-carnitine?

The most common sources of l-carnitine are beef, pork, fish, chicken, and milk. However, if you are a vegetarian, you’re left with limited options, such as milk. Fortunately, there are several l-carnitine supplements in the market that you can rely on.

Should You Go for L-Carnitine?

If you’re someone who doesn’t consume meat or fish and wants to lose some weight, you should definitely include l-carnitine in your daily diet. It’s known to help with weight loss and also helps boost your mental health, among other benefits.

However, always consume the right amount(500-2000mg or 2 grams) each day to prevent side effects of any sort.
