SteelFit Steel Burn: Unlock Fat Stores with L-Carnitine

Fat loss is one of the most common goals for fitness enthusiasts and average gym goers. On a very basic level, you need to burn more calories than you consume in order to lose weight, and if diet is on point and protein is high enough, improve your overall body composition in the process. The entire process seems very simple, however there’s a ton of misleading information out there surrounding weight loss.

Steel Burn is one of the few liquid L-carnitine products that’s actually enjoyable to drink!

Unfortunately, a large amount of it comes from the supplement industry. It’s not that products or ingredients marketed as “fat burners” don’t work, it’s that the claims which go along with them are often exaggerated. One thing you need to understand about changing your body composition is that you still have to put in the work no matter what. You still need to eat right, monitor your intake, exercise, stay hydrated, manage stress, and hopefully get 6-8 hours of sleep per night. Once you get those big rocks taken care of, then supplements can become your secret weapon!

When you look into what a typical fat burner contains, it’s normally chock full of caffeine to power you through the day, a workout, or cardio session. An effective fat burner is a lot more than just caffeine. There are several other ingredients that can help facilitate weight loss without having to make your caffeine addiction that much worse. And many of them are designed to optimize your natural fat burning processes.

If there’s one company that offers very solid stimulant free fat burners, it’s SteelFit! But what good is amplifying energy if your body can’t deliver the fatty acids to the mitochondria for use?!

There’s an ingredient for that — and it’s one that far too many dieters are deficient in lately. L-Carnitine.

SteelFit Steel Burn: 100% Carnipure For Maximal Results

Not only does SteelFit have some of the most comprehensive weight loss formulas and skin creams available, they also offer effective fat burning ingredients as stand alone products. The best example is none other than the delicious Steel Burn!

Steel Burn is 100% pure liquid L-Carnitine, which is a very common ingredient in fat burners. What makes Steel Burn really stand out is that it’s one of the few products that utilizes Carnipure and makes it taste great.

Carnipure is a trademarked ingredient developed by Lonza, a well-respected ingredient developer. By using Carnipure, you can be rest assured that every gram of carnitine on the label is pure and high quality. There are several forms of L-Carnitine on the market, but not all are created equal, which can significantly alter the effectiveness of the ingredient.

SteelFit Steel Burn Ingredient Explanation

SteelFit Steel Burn Ingredients

With Steel Burn you’re getting 100% L-carnitine from Carnipure!

Steel Burn is a top selling product for SteelFit because it simply works, it tastes great, and outperforms nearly every other L-carnitine supplement available. The brand recommends taking one tablespoon (15mL) two times per day for optimal results, and that will get you far above clinically-studied dosages of L-Carnitine.

You can use Steel Burn on its own or stack it with other comprehensive fat burners from SteelFit, such as Steel Slim, Shredded Steel, Steel Sweat, or Steel Core. It contains zero calories, which makes it suitable for anyone’s diet.

The long story short is if you have a diet that’s not very heavy in meat (especially red meat), you could likely benefit from adding L-carnitine to your supplement stack. And SteelFit does it in a way that tastes great.

Now that you know how to take Steel Burn, let’s dive into what makes it so effective and how it facilitates weight loss on a physiological level.

Here’s what one serving (15mL) of Steel Burn provides:

L-Carnitine (Carnipure) (Free-Form Base) – 3g

Since there’s only one ingredient in SteelFit Steel Burn, we’re going to cover nearly everything you need to know about L-carnitine! Starting with what it is and why it’s one of the most popular ingredients for weight loss.

  • What is carnitine?

    Carnitine is an amino acid that plays a crucial role in the metabolism of fatty acids and energy production.[1] It also helps preserve membrane integrity, stabilize coenzymes within the mitochondria, and decrease lactate production.[1] Carnitine is mainly supplied by animal-based foods, but it can be endogenously produced in the liver and kidneys.[1]

    Carnipure Logo

    Carnipure is a high quality form of L-carnitine from Lonza.

    If your main goal is to burn as much fat as possible, then it’s advantageous to have sufficient levels of carnitine around to facilitate the process. Carnitine serves as a fatty acid transporter, meaning it helps shuttle fats into the mitochondria to undergo beta-oxidation.[1]

    Beta-oxidation is a catabolic process that involves the breakdown of fatty acids to ultimately form acetyl-coA, which ends up entering the citric acid cycle to generate ATP.[1] Adenosine triphosphate, or ATP for short, is the cell’s energy currency. It’s required for nearly every physiological process, especially physical activity. The body primarily uses carbohydrates or fats to generate energy.

  • Carbohydrates vs. Fats for Fuel

    It’s well-established that during high intensity activities, such as sprinting, carbs are the primary source of fuel, because the body can quickly breakdown the glucose molecules to generate a sufficient amount of ATP.[1]

    SteelFit Supp Stack

    SteelFit has everything you need to have an incredible workout!

    Once you get into more endurance type activities such as running a marathon, then the body will preferentially burn fats.[1] This also means at rest or during low intensity exercise, such as walking, you’ll burn more fats than carbohydrates to fuel that activity because the energy demand is not very high.

    Because fatty acids have to undergo so many steps before creating an adequate amount of ATP, it makes sense that the longer the activity lasts, the more fats will be burned. So how does all of this relate to carnitine?

    If your body doesn’t have an optimal amount of carnitine available to transport the fatty acids into the mitochondria for energy production, then your ability to burn fat will be significantly reduced. As we mentioned in the intro, being in a caloric deficit, eating a high protein diet, managing stress, and sleep are all key factors to losing weight. But, taking supplements can further maximize your results by giving you an extra boost!

    Based on the role that carnitine plays in fatty acid oxidation, it would make sense that a supplemental L-carnitine would increase your ability to burn body fat and lose weight, but what does the literature have to say?

  • Weight Loss Research

    In a meta-analysis from 2016, researchers assessed the results of nine randomized controlled trials that examined carnitine’s effect on weight loss.[2] They concluded that participants who supplemented carnitine lost significantly more weight and had a lower body mass index (BMI) compared to the control group.[2]

    Other than this meta-analysis, there’s not much evidence supporting L-carnitine supplementation for weight loss. That just goes to show that fat burners don’t work unless you do! However, L-carnitine does have a multitude of other benefits it provides!

  • Exercise performance research

    Although we’ve put a large emphasis on weight loss thus far when discussing the benefits of L-carnitine supplementation, it also has several other things to offer in regards to exercise performance!

    Steel Burn Blueberry Lemonade Front

    L-carnitine offers more benefits than just weight loss, it also may boost recovery!

    In a study from 2011, lead researcher Benjamin Wall and colleagues were one of the first to show that oral supplementation of L-carnitine is capable of increasing intramuscular carnitine levels and modulates substrate metabolism in humans during exercise.[3] The subjects consisted of 14 healthy young adult males. They were either given 80g of carbohydrates or 80g of carbohydrates plus 2g of L-carnitine-L-tartrate.[3]

    The results showed that the carnitine group had on average a 21% increase in muscular carnitine levels compared to baseline, whereas the control group saw no significant difference.[3] They also found that after cycling for 30 minutes the carnitine group used 55% less muscle glycogen than the control group.[3]

    Furthermore, the participants supplementing with carnitine had around a 11% increase in work output compared to the control.[3] This landmark study was the first to show that not only could dietary L-carnitine increase carnitine levels within the muscles, but it could boost performance and spare muscle glycogen![3]

    There’s also a good amount of research showing that L-carnitine supplementation reduces muscle soreness, markers of muscle damage, acutely increases maximal oxygen uptake, improves power output, enhances blood flow, oxygen delivery, and overall recovery.[4]

    Furthermore, other studies report that L-carnitine supplementation significantly benefits the elderly by increasing muscle mass, decreasing fat mass, and reducing both physical and mental fatigue.[4]

  • How does L-Carnitine boost recovery and performance?

    More research is warranted in order to fully understand how L-carnitine improves recovery and may enhance exercise performance, but one convincing explanation is what we call the “testosterone uptake theory”.

    This comes from a study conducted in 2006 which determined the effects of L-carnitine-L-tartrate (LCLT) supplementation in combination with post exercise feeding on androgenic responses.[5] They concluded that 2g LCLT supplementation resulted in a decrease in serum levels of testosterone.[5]


    After reading a new review based upon 100 citations, we are finding fewer and fewer reasons not to take ~2g L-Carnitine each day

    That may not sound like a good thing, but the researchers speculated the reduction occurred due to an increase in muscle protein synthesis and cellular absorption of testosterone![5] Therefore, L-carnitine may enhance the endocrine system’s response to exercise.

    Furthermore, other studies have shown that L-carnitine increases mitochondrial efficiency, resulting in better energy production and enhances the cell’s ability to dispose of metabolic waste products.[6,7]

    In summary, L-carnitine has a lot more to offer than just fat loss, especially for athletes looking to optimize recovery. Now that you know nearly everything that L-carnitine is capable of, what’s the benefits of Carnipure?

  • Carnipure: The superior form of L-carnitine supplementation

    If you’ve ever tried L-carnitine in the past and didn’t notice any benefits, it’s likely that the form you used was poor quality.

    At PricePlow, we talk about the importance of quality, potency, purity, safety, and bioavailability all the time. Sometimes we sound like a broken record, but we cannot overstate the value of premium ingredients. If your body cannot properly utilize an ingredient, then you’re just wasting your time, money, and efforts.

    SteelFit Weight Loss Stack

    Three supplements designed to help you burn fat faster!

    Fortunately, there’s some great supplement companies out there, that do everything they can to formulate the best product, and SteelFit is definitely one of them. SteelFit is a huge proponent of using trademarked and patented ingredients at clinically studied dosages, which is why they chose Carnipure for Steel Burn. Carnipure is a special grade of 100% pure L-carnitine developed by a Swiss company called Lonza.[8]

    This company actually offers two different forms of premium carnitine – Carnipure crystalline and Carnipure tartrate.[9] Carnipure tartrate is a crystalized stable salt produced from Carnipure crystalline, therefore it consists of approximately 68% L-Carnitine and 32% L-tartaric acid.[9] Whereas Carnipure crystalline is classified at pure L-carnitine.[9]

    It’s important to note that both types of Carnipure are GRAS-affirmed, meaning that they are generally recognized as safe.[9] Furthermore, Lonza is a very respected and trusted company that’s been doing research and producing the highest quality form of L-carnitine in the industry for nearly 30 years. It’s not a surprise that SteelFit partnered with them for Steel Burn, because the effectiveness of the product speaks for itself.

Available Flavors

SteelFit is known for creating some great tasting products, and Steel Burn is not going to disappoint. There are several liquid L-carnitine products available, but many of them are hard to get down. Fortunately, SteelFit was able to solve that issue and make it enjoyable for you to take daily.

Not to mention, Steel Burn has zero calories, sugars, carbs, or fats, so whether you’re looking to lose weight or recover from a hard training session, it will easily fit into your diet.

Here’s an updated list of all Steel Burn’s flavor variations:

    Steel Burn Unlocks The Power of L-Carnitine

    By using the highest quality form of L-carnitine on the market, SteelFit was able to create a phenomenal product that’s simple, yet extremely effective. It may be marketed as a weight loss supplement, but the exercise recovery and performance benefits are almost more prevalent in the literature. Either way, Steel Burn can be used for a variety of different purposes and seeing Carnipure on the label ensures that you’re getting what you paid for!

    SteelFit Steel Slim Available

    Stack Steel Burn with Steel Slim for even better results!

    If you’re looking to use Steel Burn for primarily weight loss, we would suggest stacking it with a more comprehensive fat burner from SteelFit, such as Steel Slim or Shredded Steel. But, like we mentioned in the intro, you have to make sure your diet, sleep, stress, and exercise regimen are in check to truly see significant changes. If you want to pick up Steel Burn for the exercise performance and recovery benefits, then adding Steel Whey to your post workout stack is a great way to further promote muscle growth, repair, and recovery.

    SteelFit has released some phenomenal new products and flavors so far in 2020, including Peanut Butter Milkshake Steel Whey, Black Slushie Steel Pump, Steel Slim, and three variations of Steel Greens! However, sometimes it’s nice to go back in time and cover some of their best selling products, which is why we really wanted to write a post on Steel Burn. Whether you’re looking to build muscle, burn fat, or just get in better shape, SteelFit has you covered!
