L-Carnitine – Supplements for Sports & Fitness
L-Carnitine has been a well-known dietary supplement in fitness and bodybuilding for many years. It is particularly often associated with fat metabolism and fat burner products. However, it is worth taking a closer look: L-Carnitine has a specific function in the body, but taking additional L-Carnitine does not automatically mean increased fat burning or weight loss.
At Vikingstore, you’ll find various L-Carnitine products in capsules, tablets, liquid or powder form for sports and fitness.
What Is L-Carnitine?
L-Carnitine is a naturally occurring compound that the body can produce from the amino acids lysine and methionine.
Carnitine also occurs naturally in various foods. Animal-based foods, particularly meat, contain L-Carnitine.
A large proportion of the Carnitine in the human body is stored in muscle tissue.
What Does L-Carnitine Do in the Body?
L-Carnitine is involved in transporting long-chain fatty acids into the mitochondria.
Mitochondria are often simply described as the “powerhouses of the cells”. Fatty acids can be used there for energy production.
This function is one of the reasons why L-Carnitine has been strongly associated with fat burning for many years.
However, there is an important distinction:
Just because L-Carnitine is involved in transporting fatty acids does not mean that taking additional L-Carnitine automatically makes your body burn more body fat.
Is L-Carnitine a Fat Burner?
L-Carnitine is often sold in the fat burner category.
However, the term can give the wrong impression.
An L-Carnitine capsule does not simply “burn” body fat. For long-term weight loss, energy balance remains particularly important.
This includes:
- nutrition
- calorie intake
- physical activity
- training
- long-term habits
L-Carnitine does not replace a calorie deficit.
L-Carnitine in Bodybuilding and Fitness
L-Carnitine is particularly well known in bodybuilding and fitness.
It is available both as a standalone supplement and as an ingredient in various sports nutrition products.
Common forms include:
- L-Carnitine capsules
- L-Carnitine tablets
- L-Carnitine liquid
- L-Carnitine powder
- L-Carnitine shots
- combination products
Which option is best depends mainly on your personal preferences and the formulation of the individual product.
L-Carnitine Liquid
Liquid L-Carnitine is one of the most popular forms.
Liquids are easy to measure and can be a practical option for people who do not like swallowing capsules or tablets.
When comparing different products, check how much L-Carnitine is actually provided per serving.
A bigger bottle does not automatically mean a higher L-Carnitine dosage.
L-Carnitine Capsules & Tablets
Capsules and tablets are convenient, easy to carry and already portioned.
When comparing products, check:
- L-Carnitine per capsule or tablet
- L-Carnitine per daily serving
- number of capsules or tablets per daily serving
- number of daily servings per package
The number of daily servings is particularly useful when comparing the actual cost of different products.
L-Carnitine Powder
L-Carnitine is also available as a powder or as an ingredient in various powdered supplements.
Powders can easily be mixed with water or other drinks.
Again, pay attention to the actual amount of L-Carnitine provided per serving.
What Is L-Carnitine L-Tartrate?
Sports supplements often contain L-Carnitine L-Tartrate.
This is a compound consisting of L-Carnitine and tartaric acid.
When comparing products, read the product information carefully.
The amount of a Carnitine compound listed on the label does not necessarily correspond to the same amount of pure L-Carnitine.
What Is Acetyl-L-Carnitine?
Acetyl-L-Carnitine, often abbreviated as ALCAR, is an acetylated form of L-Carnitine.
Acetyl-L-Carnitine and standard L-Carnitine are not exactly the same, although both belong to the Carnitine family.
Different products may therefore use different forms of Carnitine.
L-Carnitine Before Training?
L-Carnitine is often taken before training.
This is partly because many products are marketed for use around workouts.
However, this does not mean that L-Carnitine works like a traditional pre-workout booster with an immediate noticeable effect after consumption.
L-Carnitine is not a stimulant-based pre-workout.
Follow the manufacturer’s recommended use for the individual product.
Does L-Carnitine Contain Caffeine?
Pure L-Carnitine does not contain caffeine.
Combination products may, however, contain caffeine or other stimulating ingredients.
This is particularly important with products marketed simultaneously as fat burners or pre-workouts.
If you train in the evening or are sensitive to caffeine, always check the ingredient list.
L-Carnitine and Weight Loss
L-Carnitine has been marketed in connection with weight loss and fat burning for many years.
It is important to keep expectations realistic.
A dietary supplement cannot replace an appropriate diet or a calorie deficit.
If your goal is weight loss, your long-term energy balance and your nutrition and activity habits play a major role.
A high L-Carnitine dosage does not turn a high-calorie diet into a weight-loss diet.
L-Carnitine in Foods
Carnitine occurs naturally in various foods.
Animal-based foods, particularly meat, generally contain higher amounts of Carnitine.
Plant-based foods usually contain considerably smaller amounts.
The human body can also produce L-Carnitine from the amino acids lysine and methionine.
L-Carnitine for Vegans and Vegetarians
Because Carnitine is found primarily in animal-based foods, L-Carnitine supplements are also discussed in connection with vegetarian and vegan diets.
However, not every L-Carnitine supplement is automatically vegan.
Capsule shells, flavourings or other ingredients may be of animal origin.
If you are looking for a vegan product, check the manufacturer’s product information and labelling.
More L-Carnitine Is Not Automatically Better
As with many supplements:
A bigger number on the label does not automatically make a product better.
When comparing products, check:
- Which form of Carnitine is used?
- How much L-Carnitine does one serving provide?
- What is the recommended daily serving?
- How many servings are included?
- Which additional ingredients are included?
- Does the product contain caffeine?
- What is the manufacturer’s recommended use?
How to Compare L-Carnitine Products
Two L-Carnitine products may look very similar at first glance while having quite different formulations.
When comparing products, pay particular attention to:
- form of Carnitine
- amount per serving
- serving size
- number of servings
- product format
- additional ingredients
- cost per daily serving
Don’t compare only the price of the bottle or container – compare the actual amount of L-Carnitine provided per serving.
