Metabolic Burn: A Stimulant-Free Fat Burner

When it comes to losing weight, diet and exercise are the only absolutes, but there are also a number of helpful nutritional supplements that can aid you in your goals. Fat burning supplements support a range of different functions within the body, from stimulating the central nervous system in order to increase the heart rate, to raising the body temperature and energy output through thermogenesis. Many of the most potent fat burning ingredients have been shown to offer exceeding results, but not without some unwanted side-effects, which has caused many users to turn to a stimulant-free fat burner, instead. True Nutrition now offers a safe and effective weight loss alternative in our stimulant-free fat burner capsules, Metabolic Burn!

Caffeine is perhaps the most commonly-used stimulant on the market. It is not only an active ingredient in many coffees and teas, but also in a variety of sodas, energy drinks, and sports supplements. In addition to providing mental awareness and increased energy, caffeine has also demonstrated weight loss potential by acting upon the central nervous system and metabolism through an increase in heart rate1. When used in moderation, caffeine may offer several potential health benefits, but an overuse of the material may lead to dependency or a variety of problematic side-effects, including anxiety, restlessness, irritability, and insomnia2. It is important to limit the caffeine content in your daily intake in an attempt to avoid these unwanted effects. This is especially true when attempting to combine fat burners with other energy-boosting supplements, since you will often encounter caffeine as a leading ingredient in many of the most popular fat burners that are currently being offered.

There are many additional materials that function similarly to caffeine, with the intended effect of stimulating the central nervous system to increase heart rate, thereby increasing the metabolic function that controls our ability to expend energy3. These include the alkaloids Synephrine HCL, a synthetic derivative of bitter orange extract, and Yohimbine HCL, an extract of the yohimbe bark. Similar precautions should be taken when considering either of these materials either independently, or in conjunction with caffeine, as the overuse of stimulating ingredients found in many common fat burners could potentially lead to high blood pressure or other cardiovascular concerns5,6.

How is True Nutrition‘s stimulant-free fat burner, Metabolic Burn, different?

Metabolic Burn works to help promote healthy weight loss using alternate means without the need for an accelerated heart-rate.* Here, we will explore the potential health benefits of the active ingredients Green Coffee Extract, African Mango Extract, Raspberry Ketones, and L-Carnitine, and how they may be able to work together to provide an increase in overall fat reduction*:

  • Green Coffee Extract: Studies that have been conducted in to the efficacy of Green Coffee Extract have yielded interesting results in regards to the suppression of fat absorption and fat metabolism in the liver, which could contribute to effective weight loss7, 8.
  • African Mango Extract: Similar to the Green Coffee Extract, studies suggest that African Mango Extract may show the potential to help increase the body’s natural ability to metabolize glucose and fat through the increased production of the protein-based hormone adiponectin9,10.
  • Raspberry Ketones: A study conducted by the Ehime University School of Medicine claims that Raspberry Ketones may also help in preventing or improving obesity levels by altering the metabolism of fat in the liver11. A separate study suggests that Raspberry Ketones exhibit thermogenic properties similar to those of capsaicin, which may serve to increase the body’s energy expenditure12.
  • L-Carnitine: Research has shown that L-Carnitine may serve a vital role in the transportation of fatty acids into the mitochondria in the production of energy14. The increased supplementation of L-Carnitine in conjunction with diet and exercise may then help to increase fat burning potential.*

In effect, True Nutrition‘s Metabolic Burn formula combines an efficacious dose of each of the above ingredients in order to help improve the body’s natural fat burning processes, including the potential to increase the liver’s ability to metabolize sugars and fats, while increasing the body’s thermogenic response.* These claims may only be supported in conjunction with a sensible eating plan and moderate exercise.*
