What Is L-Carnitine? How Does It Work?


The Complete Guide to L-Carnitine


Getting lean takes more than a wish and a dream.

You need to follow a proper goal based nutritional plan, exercise and you need supplements — the right supplements, of course.

Enter pure L-Carnitine. Proven to speed up fat loss, L-Carnitine is invaluable for anyone looking to take their fitness to the next level. It’s a weight loss supplement, sure, but there’s a catch — it really works.


What Is L-Carnitine? How Does It Work?


L-Carnitine is the active form of carnitine, a dipeptide made from the essential amino acids lysine and methionine. 


So, how does it work? The mechanism is deceptively simple. L-Carnitine transfers long-chain fatty acids into the mitochondria. Mitochondria are little ‘organelles’ (organs of the cell, so to speak) that break down nutrients and create energy.

By moving these fatty acids into the ‘power plants’ of the cell, L-Carnitine opens them for oxidization. Oxidization breaks fatty acids down into energy — the basic function of metabolic energy.

That results in more energy, less fatigue, and less appetite.


Where Do I Get L-Carnitine?


Everyone’s body produces a little L-Carnitine on its own. If your body has lysine and methionine (two amino acids), it can make L-Carnitine on its own. Of course, the amount of L-Carnitine your body produces is not enough to make a dramatic difference in your fitness journey. That’s where supplements come in!

It is true that you can pick up small doses of L-Carnitine in your diet. Animal products are a particularly potent source — especially red meat. Dairy products also contain a reasonable amount of L-Carnitine.


Different Forms and Blends of L-Carnitine


L-Carnitine took the fitness world by storm. A fat burner that actually works? A supplement proven to help your cells burn fatty acids? Talk about a winner!

Of course, once the magical words “L-Carnitine” became popular, products began to flood the market. Companies offered different carnitine blends and mixes — some of which are not ideal for fat loss!


L-Carnitine Tartrate


Consider L-Carnitine Tartrate.

This is the most popular form of Carnitine in supplements. It is great for athletes because it is quickly absorbed by the body and put right to work. Its benefits include the potential to help you avoid muscle soreness. Plus, it can help you recover more quickly following a workout.

However, L-Carnitine Tartrate blends are usually only around 60-70% pure L-Carnitine — the rest is tartaric acid. The real benefit of this type of supplement comes from the base L-Carnitine, not from unnecessary additives.


Acetyl L-Carnitine


Acetyl L-Carnitine (known as ALCAR) is the most popular form of Carnitine aimed at improving brain and nerve health. Now, don’t get us wrong — ALCAR is fantastic for brain health. The acetyl group allows the supplement to pass easily through the blood-brain barrier. The subsequent production of the neurotransmitter acetylcholine pays great dividends to the human brain!

The biosynthesis of acetylcholine improves brain function and can reduce mitochondrial aging in the brain.


Propionyl L-Carnitine


Yes, there’s more than just those two. How about Propionyl L-Carnitine?

Propionyl L-Carnitine is ideal for circulatory issues including high blood pressure. This form increases nitric oxide production inside the body, which helps to improve blood flow. Therefore, it can also help with peripheral vascular disease.


Okay, But I Want Pure L-Carnitine. What Gives?


Good choice.

There’s no doubt that some L-Carnitine blends offer their own unique set of benefits. But you’re looking to burn calories to lose fat, right?

For that, you need pure, 100% L-Carnitine.

Dosages of Ingredients in 1UP Nutrition’s L-Carnitine 3000


Each L-Carnitine 3000 fat burner comes with 32 servings of pure L-Carnitine. Each serving consists of 3000 mg of supplement. To keep things simple, we made each serving the size of a standard tablespoon (15ml).

No complicated mixing or matching. No wondering how much to take. One tablespoon, one serving, and that’s it.


How to Use 1UP Nutrition’s L-Carnitine 3000


Supplements need to be easy to use. After all, you need your focus to be in the gym, not the kitchen!

1UP Nutrition’s L-Carnitine 3000 is especially easy. Give the bottle a proper shake before use. Pour the supplement into a standard, 15ml tablespoon until the utensil is full.

We recommend taking your dosage with a meal. We recommend that your meal includes some form of carbohydrates — it helps the body absorb and process the L-Carnitine dose.

You’ll want to use 1UP Nutrition’s L-Carnitine 3000 once to twice a day. Be sure to refrigerate the bottle after opening.


Wait a Minute...You Mentioned Carbohydrates. What About Ketogenic Diets?


Ketogenic diets are fantastic for weight loss, and for good reason — they work!

A ketogenic (keto, for short) diet is nothing more than a low-carb, high-fat eating regimen. The basics? Reduce your carbohydrate intake, increase your fat intake, and reap the rewards!


How Does a Keto Diet Work?


Let’s take a step back.

Where does your body prefer to get energy? Easy — glucose (blood sugar). Your body likes to metabolize glucose (obtained from carbs) because it’s easier than burning fat.

Besides, your body likes fat, even if you don’t. After all, what is fat but stored energy? Your body knows that energy can come in handy down the road.

keto diet works by forcing the body to switch where it gathers energy. If carbohydrates are unavailable or in short supply, the body knows it must start using up its fat stores. The body then enters ketosis — a metabolic state where the body burns fat for energy.


Okay, What About L-Carnitine?


Same principles apply! L-Carnitine helps your body break down fat for energy. If you’re on a keto diet, your body is already kicking fat to the curb.

L-Carnitine takes this process to the next level.


Benefits of 1UP Nutrition’s KETO L-Carnitine 3500


1UP Nutrition’s KETO L-Carnitine 3500 is specifically designed for individuals on ketogenic diets. It’s a non-proprietary formula, so you know exactly what you’re putting in your body.

Of course, we use only the highest quality ingredients from the best sources.


Helps Convert Fats to Energy


L-Carnitine works by transferring fatty acids to the cell’s mitochondria. Once the fatty acids enter the mitochondria, they get broken down into energy. KETO L-Carnitine 3500 works the same way as L-Carnitine 3000, except the former emphasizes ketogenic diets.


Fuels Ketogenic Weight Loss


A ketogenic diet is a fantastic way to shed pounds. Adding KETO L-Carnitine 3500 to a regular exercise regimen can help fuel your weight loss. Boosting your body with the extra Ketone Body Salts and L-Carnitine present in KETO L-Carnitine 3500 means faster gains than ever before.

The more fat you burn, the quicker you drop unwanted pounds!


Fuel for Muscle Growth


KETO L-Carnitine 3500 has all the same muscle benefits as L-Carnitine 3000. Now, you are getting less L-Carnitine per serving, but the addition of Ketone Body Salts more than balances out.


This unique blend of L-Carnitine and Ketone Body Salts can help boost muscle growth, recovery, and repair.


Thermogenesis and Fat Oxidation


Improved thermogenesis (the production of heat) is another big benefit of KETO L-Carnitine 3500.

Your body naturally produces heat to maintain homeostasis and process food. A good portion of your daily caloric intake produces this heat and processes food. Boosting your body’s natural heat production can result in an enhanced metabolism.

In fact, thermogenic supplements can increase energy expenditure and fat oxidation


Enhanced Endurance


L-Carnitine supplementation can have a positive effect on athletic endurance. In fact, acute L-Carnitine supplementation has led to lowered heart rates during exercise and improved endurance.

For individuals on ketogenic diets, the lack of carbohydrates may prove problematic initially. The body needs time to adapt to the diet — supplementing your ketogenic diet with KETO L-Carnitine 3500 does just that.

That extra boost of Ketone Body Salts and other ingredients gives you that extra edge when you need it!


In-depth Ingredient Breakdown of 1UP Nutrition’s KETO L-Carnitine 3500


KETO L-Carnitine 3500 is a transparent, non-proprietary blend of quality ingredients.

That means no hidden ingredients and no unnecessary additions.


Ketone Body Salts


Every serving of KETO L-Carnitine 3500 contains a mix of Ketone Body Salts. The mix consists of goBHB® (calcium beta-hydroxybutyrate, magnesium beta-hydroxybutyrate, and sodium beta-hydroxybutyrate). This unique ketone body compound solution is carb-free and perfect for everyone considering a keto diet.




More efficient fatty acid transfer means faster fat-burning. The L-Carnitine present in every serving of KETO L-Carnitine 3500 aims to enhance metabolic performance and overall health.




Also known as Gamma-Butyrobetaine, LeanGBB can help with weight loss — it converts GB hydroxylase into more carnitine. It works hand in hand with L-Carnitine to maximize fat oxidation.




An extract of a West African spice, Paradoxine contributes to increased fat loss and enhanced thermogenesis.




Derived from black pepper, BioPerine is fantastic at helping your body to absorb nutrients. Known as bioenhancement, BioPerine can increase the absorption of vitamins C, A, B-6, and more.


Dosages of Ingredients in 1UP Nutrition’s KETO L-Carnitine 3500


Each serving of KETO L-Carnitine 3500 comes with a special blend of the above ingredients. A single serving consists of 2000 mg of Ketone Body Salts, 1500 mg of L-Carnitine, 25 mg of LeanGBB, 15 mg of Paradoxine, and 5 mg of BioPerine.

And, of course, there is just enough water, citric acid, preservative, and flavoring to bring out the best of 1UP Nutrition’s KETO L-Carnitine 3500’s blend.


How to Use 1UP Nutrition’s KETO L-Carnitine 3500


Using KETO L-Carnitine 3500 is simple.

Shake the bottle very well before each use. Treat it as a pre-workout — take a single 15 ml spoonful (one standard tablespoon) before a workout.

It’s recommended that you refrigerate the bottle after opening.
