Top 10 Best Stimulant-Free Fat Burners For 2016

lean-xt stimulant free fat burnerThe supplement industry is saturated with products claiming to help you achieve the body of your dreams. Walk into any supplement retail store and you’re likely to notice that every company has their own unique, patented blend of “cutting-edge” ingredients purported to give you that toned physique you’ve always wanted.

Much to the chagrin of consumers, many of these supplements do very little to help burn fat, but they certainly do a great job of burning a hole in your pocket.

Therefore, this article will give you some concrete, reliable advice about which supplements actually do help burn fat and elevate metabolic rate, without the use of nervous system stimulants such as caffeine and yohimbine. 

With that in mind, let’s move on and find out just what stimulant-free fat burning ingredients are worth your while.

Notable Stimulant-Free Fat Burning Ingredients

Now we can get to the matter at hand of which supplement ingredients  to consider for boosting metabolic rate without stimulating the nervous system. The ingredients covered in this section can be used indefinitely unless otherwise noted.

Raspberry Ketone

Raspberry ketone is the major chemical found in raspberries (Rubus idaeus) that gives them their ruby red color. It is actually similar in chemical structure to capsaicinoids, therefore providing many of the same fat-loss benefits. Raspberry ketone has been shown to significantly increase adrenaline-induced fat breakdown in the body. [1] Raspberry ketone also reduces the small intestine’s absorption of dietary fat, thus reducing calorie intake.

DosingTypical doses for raspberry ketone range from 200-400mg per day (divided into at least two doses), with one of those doses being 30-60 minutes before exercising.

Acetyl-L-Carnitine (ALCAR)

L-carnitine is an important biomolecule responsible for transporting fatty acids into cells for generation of energy. Acetyl-L-Carnitine (ALCAR) is a well-absorbed form of L-carnitine and has been studied somewhat extensively in recent years.  ALCAR has been shown to reduce body fat in rats through a variety of mechanisms. [2] It also appears that ALCAR increases the body’s ability to burn fat for energy, making it ideal to take before exercising. [3]

Dosing—1000mg of ALCAR at a time is what is supported by scientific literature. This dose can be taken twice per day, with one dose coming preferably 30-60 minutes before exercising.

Conjugated Linoleic Acid (CLA)

CLA is a trans-fatty acid that may help to increase lean body mass and produce a variety of other health-promoting effects as an antioxidant. CLA works by interfering with an enzyme in the body called lipoprotein lipase (LPL) that helps your body store fat and also helps your body use its existing fat for energy. Thus, by impeding LPL, you prevent fat storage and enhance the utilization of free fatty acids in the body.

Scientific literature on CLA’s fat loss capacity is a bit mixed with regards to results.  A recent research review paper pooled data from 18 human studies and found that CLA produces small, but significant losses in body fat when compared to placebo. [4]

Dosing—1000mg up to 3 times per day is a standard dose of CLA for aiding fat loss

Forskolin

Forskolin, a compound derived from the roots of Coleus forskohlii, increases intracellular cAMP levels, which in turn boosts metabolic rate and energy production.[5] Forskolin has other ergogenic benefits as well, including better nutrient partitioning, reduction in blood pressure and relaxation of the arteries.[6]

Dosing—Research suggests that a sufficient dose of Coleus forskohlii extract for fat loss purposes is about 500mg per day (at 10% forskolin concentration),  split into two even doses.

Garcinia Cambogia

The Garcinia Cambogia tree, found mainly in Southeast Asia, is a small fruit rich in hydroxycitric acids (HCA). HCA is purported to have appetite-suppressing functions by increasing levels of serotonin in the brain. Increasing serotonin levels has been shown to decrease food intake and enhance mood, but this has minimal/unreliable effects on weight loss.[7]

Dosing—Typical research dosages for fat loss are 1000mg Garcinia Cambogia (at 50% HCA) taken three times per day before meals.

7-Keto DHEA

7-Keto DHEA is a metabolite of DHEA (dehydroepiandrosterone), a natural hormone produced by the adrenal glands. 7-Keto DHEA may boost levels of the active thyroid hormone (T3) and regulate cortisol levels, both of which have positive effects on fat loss and metabolic rate. [8, 9] 7-Keto DHEA does not convert into the sex steroids (testosterone and estrogen), like DHEA does, and thus can have many of the positive effects of DHEA without any unwanted side effects.

Dosing—Typical supplemental dosage of 7-keto is 200-400mg daily, split into two equal doses.

Pyrroloquinoline Quinone (PQQ)

PQQ is a natural compound contained in quinoproteins (often found in bacteria), and is primarily retrieved from fermented soybeans. It is hypothesized that PQQ elevates metabolic rate via increasing the number of mitochondria within cells, a process referred to as mitochondrial biogenesis. Furthermore, PQQ appears to act as a cellular messenger that mimics some of the most basic effects of physical activity and increases the body’s production of the hormone irisin. [10]

In humans, irisin release is thought to be one of the most important physioloigcal ramifications of physical activity, as circulating irisin levels are negatively correlated with age, insulin resistance, cholesterol, and adiponectin levels and positively correlated with fat-free mass and ghrelin levels.

Dosing—Placebo-controlled studies in humans show consumption of PQQ at 20mg and 60mg per day is effective and safe.

Guggul Plant Extract

Research is somewhat scarce on guggul, but it is presumed to boost metabolism by increasing thyroid hormone levels. Guggulsterones, the active components of guggul plant extract, have only shown thyroid levels to increase in rats and the dose was exceptionally high from what is recommended in humans. [11] 

Dosing—A standard dose of guggul (plant extract) is 400-500mg taken three times daily with meals. If using pure guggulsterones, a dose of 25mg taken three times per day with meals is recommended.

BulkSupplements is a solid resource for buying bulk quantities of a single ingredient. In this case, you can buy CLA (150 servings of 1500mg) on Amazon.com for $17.96, which is a pretty great value. These CLA capsules provide a small amount of vitamin E as well, giving them a slight edge over CLA 1250 by Sports Research.

#7 – Carne Diem by Magnum Nutraceuticalsimage_prodprod4020004_largeimage_x_450_white

Magnum Nutraceuticals has undergone a recent rebranding of their whole line and really pushed their products as being “pharmaceutical grade.” We like how they don’t hide ingredients behind proprietary blends and they have a reputation for being clean and fairly solid from a formulation standpoint. The main thing holding Magnum back is their prices, which unfortunately seem a tad high for their ingredient profiles. Nevertheless, Carne Diem is a great option for stimulant-free fat loss if you don’t mind paying a little extra.

#6 – Carnigen by Evogenimage_prodprod2390038_largeimage_x_450_white

Evogen is a company founded by bodybuilding “guru” Hany Rambod. While his formulations are generally sound, the price points for some of his products are a bit costly. That being said, Carnigen is a contender in the stimulant-free fat loss realm. We couldn’t notch it much higher on our list, though, due to the proprietary blend of four different L-carnitine forms.

 #5 – 7-KETO by Applied Nutraceuticalsimage_prodprod3030005_largeimage_x_450_white

Applied Nutraceuticals has a new “Pure Series” of supplements that are single-ingredient products at a highly affordable price point. 7-Keto gets our nod as a mid-range stimulant-free fat loss amplifier thanks to having a generous 100mg of 7-Keto DHEA per serving, while costing less than $0.50 per day for a month supply.

#4 – Pure Forskolin Extract by NutraFX61v4ymuytsl-_sl1000_

NutraFX comes in as number four on our list with its forskolin extract supplement. We like this product particularly for its 50mg forskolin content per capsule (which is quite a dose). A month supply, assuming you take two capsules per day, only runs $18.99 on Amazon.com.

#3 – CLK by Cellucorimage_prodprod980032_largeimage_x_450_white

Cellucor has been around for quite some time, and CLK breaks into the top three on our list thanks to its formula containing several efficacious stimulant-free fat loss ingredients. If it wasn’t for the proprietary “toning” blend, it may have cracked a higher ranking, but we can’t justify it without knowing the quantities of the ingredients in that blend. The price point for CLK definitely seems a bit high too, costing about $1.33 per serving.

#2 – QuadraLean by RSP Nutritionimage_prodprod1800023_largeimage_x_450_white

QuadraLean may not look all that fancy, and the formula does contain a proprietary blend, but it’s still a great option thanks to its ingredient selection and price. Given the ingredient amounts, you’d be best served to take 6 capsules (2 servings) per day, yielding a 25-day supply for just under $23 on bodybuilding.com.

#1 (TOP-RATED) – Lean XT by Jacked Factorylean-xt

It actually wasn’t too tough for us put Lean-XT as the best stimulant-free fat loss amplifier thanks to its 100% transparent formula with proper doses of each ingredient. What really gives Lean-XT the edge is the value for what you get. It may not be all flashy like other products, but the formula is scientifically sound and priced very reasonably. If you’re looking for superior stimulant-free fat loss, then Lean-XT is as good as it gets!

Wrap-Up

So there you have it, five key supplements/ingredients to consider that will propel your fat-loss efforts by increasing metabolic rate. It should go without saying that these supplements should not be the foundation of your fat-loss plan; even though they elevate your metabolic rate, they are not a replacement for poor lifestyle choices.

The old adage “calories in versus calories out” is ultimately what matters at the end of the day to determine whether you will lose fat, no matter how many supplements you take.  It is imperative that you have a sound diet and exercise regimen before spending your hard-earned money on supplements. But in conjunction with a healthy lifestyle, effective stimulant-free fat burning supplements will certainly help sculpt your physique.
