What Actually Carnitine is?

In the short term “L-Carnitine” is a supplement that can help you burn fat and convert it into energy without causing any harm to your muscles. Additionally, L-Carnitine appears to be essential for bodybuilding success.

Carnitine is an ammonium compound produced by the liver and kidneys. It serves as a transporter of long-chain fatty acids into the mitochondria to be oxidized for energy production and therefore plays a key role in the regulation of lipid metabolism.

Accordingly, both scientists and sports nutritionists alike have entertained the notion that supplementation could increase the bioavailability of carnitine and enhance the overall capacity for lipid metabolism.

Animal food products like fish and meat are also rich sources of L-carnitine. The name L-carnitine is derived from the Latin word ‘carnis,’ which means meat.

Our body produces L-carnitine and stores it in our muscles and heart tissue, individuals may suffer from a deficiency like vegans, those under undue stress or anxiety, or those with specific genetic issues.

With so many products flooding the supplement industry, it is obvious to get confused while picking the right one for you. Let make us assist you to pick and choose the right one.

One of the things we like most about Double Wood Supplements Acetyl-L-Carnitine is the fact that it offers users some flexibility when it comes to dosage.

The base dosage is two 500 mg capsules, but according to the manufacturer, 2-4 capsules per day are optimal, not exceeding six capsules (3000 mg). However, more than 3000 mg per day increases the risk of adverse effects.

This dosing range allows users to start small and work up to a larger amount if they feel it is right for them and they can tolerate it well. We think this is a great feature as it makes the supplement more accessible for everyone, regardless of their starting point.

Many users report that they feel an energy boost from this supplement that is different than a cup of coffee; the body is ready for what you need it to do.

The person who volunteered to test this supplement reported feeling the benefits quickly and seeing significant increases in endurance and stamina during resistance training.

What are the benefits associated with L-Carnitine?

L-carnitine is an amino acid that aids in the transport of fats to the mitochondria, where they’re converted to energy.

It plays an essential role in weight loss by burning fat for fuel, which could help you lose weight both directly and indirectly.

See below for five extraordinary benefits of L-carnitine weight loss supplement and how it can help you to shed pounds.

1. L-Carnitine Burns Fat

L-carnitine is an amino acid that can help your body burn fat more efficiently. By increasing levels of L-carnitine, you can decrease the amount of fat your body stores, especially visceral belly fat. Visceral belly fat is the type of fat that surrounds your organs and can lead to fatty liver disease and other health problems.

2. Provide energy During and After a workout

As your body’s ability to burn fat increases, so does your energy level. L-carnitine not only helps you burn more fat with every workout, but you also get more energy for better workouts and an active lifestyle.

3. Boosts Metabolism

Adding that extra energy from your daily intake into your exercise routine will help you to push harder and increase the intensity, which in turn provides a nice metabolism boost. A more efficient metabolism is great for weight loss because it means you’ll be burning more calories – even when you’re resting.

4. Improve Heart Health

L-carnitine is also linked to improvements in patients with severe heart disorders, such as coronary heart disease and chronic heart failure.

In one study, 2 grams of acetyl-L-carnitine per day resulted in an almost 10-point drop in systolic blood pressure — the top number of a blood pressure reading and an important indicator of heart health and disease risk.

5. Increase Athletic Performance

The evidence is mixed when it comes to L-carnitine’s effects on sports performance.

However, several studies note mild benefits associated with larger or more long-term doses.

L-carnitine may also benefit:

  • Recovery: May improve exercise recovery.
  • Muscle oxygen supply: This may increase the oxygen supply to your muscles.
  • Stamina: May increase blood flow and nitric oxide production, helping delay discomfort and reduce fatigue.
  • Muscle soreness: May reduce muscle soreness after exercise.
  • Red blood cell production: This may increase the production of red blood cells, which transport oxygen throughout your body and muscles.

Carnitine Side Effect

L-carnitine is safe like other supplements. But high dosage can cause side effects such as stomach upset, heartburn, diarrhea, and seizures. It can also cause urine, breath, and sweat to have a “fishy” odor. Avoid using D-carnitine and DL-carnitine. These forms of carnitine might block the effects of L-carnitine and cause symptoms that resemble L-carnitine deficiency.

Acetyl-l-Carnitine vs L-Carnitine

L-carnitine is an amino acid that can be found in foods like beef, chicken, fish, dairy, and other natural sources. L-carnitine dietary gaps are commonly compensated for with L-carnitine supplements.

Acetyl L-carnitine is a commonly used supplement to support brain health. It is similar to L-carnitine but can cross the blood-brain barrier, making it more effective in boosting brain function. Acetyl L-carnitine supplements are used to improve energy and focus, mood, memory, and male reproductive health.


What is the best time to take l-carnitine?

Most scientific studies recommend taking L-carnitine about 1 hour prior to exercise for the best results. However, if you’re also looking to take advantage of the other benefits that L-carnitine offers like recovery and weight loss support, taking it after your exercise routine can still be effective.

How Long You Should Take L-Carnitine?

L-carnitine is likely safe when taken for up to 12 months, however; it can cause side effects such as stomach upset, heartburn, diarrhea, and seizures. In addition, L-carnitine can also cause urine, breath, and sweat to have a “fishy” odor. It’s best to avoid using D-carnitine and DL-carnitine.

How much l-carnitine should I take?

A typical dose of carnitine is 500mg to 2g per day. This is enough to help with fat burning, promote endurance, and improve recovery. Carnitine also has ergogenic benefits, which means it helps the body produce energy.

Is injectable L carnitine worth it?

The L-carnitine injection is most commonly known as a fat burner, but the research on its benefits is mixed. While it is unlikely to cause significant weight loss, studies do support its use for overall health, brain function, and disease prevention. Those with lower levels of L-carnitine, such as older adults, vegans, and vegetarians, may also benefit from supplements.

Is l-carnitine effective?

Yes, it is, some research shows that l-carnitine is the perfect supplement to lose fat from the belly or another area of subcutaneous fat.

Other supplements, such as caffeine, green tea extract, and conjugated linoleic acid (CLA), have also been shown to have fat-burning properties. The best approach to weight loss is a comprehensive one that includes a healthy diet and regular exercise, rather than relying solely on supplements.

What is the best time to take l-carnitine for bodybuilders?

The best time to take L-Carnitine may vary depending on individual needs and goals. Some bodybuilders prefer to take it before a workout to help boost energy and fat burning, while others take it post-workout to help with recovery.
