Blade Fat Burner is a supplement that helps men burn fat by increasing lipid and overall metabolism.

Most existing workout supplements fall into one of two camps: muscle recovery enhancers or fat burners. Muscle recovery supplements are designed to maximize muscle gain post-workout, while fat-burning supplements give you more energy and kickstart your metabolism to burn more fat. 

Blade Fat Burner from Blue Star is designed to ramp up your metabolism so you have more energy for workouts and burn more fat while exercising. It markets itself as the newest and most potent fat-burning supplement designed specifically for men. It also claims that all the product’s key ingredients have been clinically verified to be safe and effective.  

There are other fat burners on the market, such as Skald and Animal Cuts. Workout supplement manufacturers make various claims about their products, ranging from the mundane to the extraordinary.

The problem is that most of these supplements are not regulated by the FDA, and there are no general regulations surrounding the manufacture and sale of workout supplements, so it’s hard to separate the wheat from the chaff.

Our review today covers Blue Star’s Blade fat burner, which is claimed to offer 24-hour fat burning. We will discuss its pros, cons, cost, where to find it, and whether or not you should bother buying.

Overview: Blade Fat Burner

Blade Fat Burner is designed to help men burn fat quickly. Blade claims to be made from an “award-winning formula” and is stronger than any other fat-burning supplement on the market. The bottle says the product promotes “24-hour” fat burning, ensuring your metabolism is boosted around the clock.

Blue Star claims that Blade has been developed and tested on humans to be efficacious. Many nutrition supplement companies base their health claims on studies involving rodents, so Blue Star’s claim, if true, puts it a leg above the competition. However, just because they say so does not make it accurate.

Blade is one of the most popular supplements on several bodybuilding websites, such as, and many customer reviews speak highly of the product. 

Blade also includes natural stimulants to increase energy and endurance while training. It has several claimed effects that all combine to give you the most efficient exercise. The manufacturers recommend starting by taking one supplement each morning and increasing the dosage to reach your desired energy levels.  

About Blue Star

Blade is made by Blue Star Nutraceuticals, a California-based nutrition and supplement company. Blue Star is a pretty well-known company in the fitness supplement world, and they have a decent internet presence. They claim to be 15 years ahead of other companies and have been pushing the envelope on new workout supplements. 

Blue Star prides itself on the scientific backing of its products. According to their website, all their products were designed and verified via human testing, a bold claim if true. They say that each product goes through over 1,000 hours of research before manufacturing and that they refuse to sell a product unless there is proof that it works.

Blue Star Nutraceuticals does have a verified BBB page, but it has low reviews. Most of these negative reviews seem to be about their shipping and billing practices, though, not the products themselves. 

Blade Fat Burner Pros & Cons

Blade fat burner has several ingredients, which will be discussed later, but let’s look at the pros and cons of this supplement.


  • Provides energy for more efficient exercise
  • Stimulates lipolysis to burn fat
  • Increases body heat generation (thermogenesis)
  • Regulates appetite


  • Stimulants can be harsh in high doses
  • Yohimbine may have severe side effects
  • May interact with medications for heart or blood pressure problems

Blade Fat Burner Ingredients

The main ingredients in Blade are CH-19 sweet pepper, acetyl-L carnitine, green tea extract, caffeine, bitter orange, Rauwolscine, and Huperzine.

The first ingredient, CH-19 sweet pepper, is a mainstay in workout supplements. Most fat burners use some kind of pepper extract as it induces thermogenesis and raises the body’s temperature, making it easier to burn fat. The introduction of Acetyl-L carnitine is interesting, and Blue star claims it can help give you energy for better exercise. 

Rauwolscine is an isomer of yohimbine. It is found in plants like Rauvolfia vomitoria and Yohimbe. Yohimbine has been shown to induce increased lipolysis in men due to its ability to bind to and block alpha-2 adrenergic receptors. By blocking these receptors, rauwolscine increases norepinephrine concentration leading to an increase in lipolysis.

Bitter Orange (Advantra Z®) is a standardized active ingredient, p-synephrine, that binds to β (beta) receptors in the nervous system to induce lipolysis (fat burning).

Caffeine has been shown to increase metabolism and fat burning. Green tea extract has also been shown to stimulate thermogenesis. However, this effect has been observed to be more potent when combined with caffeine.

Green tea and caffeine are found in many weight loss supplements such as Skald. They are both effective at curbing the appetite, which is why they are included in many fat burner supplements.

Blade Fat Burner Side Effects

Overall, the ingredients in Blade Fat Burner are effective; however, some have pretty questionable side effects. Bitter Orange and Yohimbine are not too dangerous on their own, but they can have serious side effects when mixed with caffeine, which is one of Blade’s main ingredients. 

Caffeine can have a negative interaction with yohimbine and bitter orange, leading to low blood pressure, fatigue, and, in severe cases, fainting and loss of consciousness. We recommend being extremely careful when taking any supplement that combines these ingredients. 

The most commonly reported side effect from Blade is increased heart rate from the caffeine. This is a common problem with caffeine-containing supplements and can be dealt with by taking a smaller dose. 

Where to Buy Blade Fat Burner


You can buy Blade directly from Blue Star’s website or third-party retailers like Amazon. Their website says you can buy Blade from select physical retailers, but it does not provide a list of those stores. A 120-capsule canister of Blade costs $79.99

Blade Fat Burner: Final Verdict

Most ingredients in Blade have some pretty solid evidence backing their efficacy and are more or less safe, but you need to be extremely careful, considering Blade mixes caffeine with bitter orange and yohimbine. Under the right (or wrong) circumstances, these ingredients can interact to have adverse effects. 

That said, Blade fat burner has been proven to increase thermogenesis and lipolysis, leading to body fat loss. It’s moderately priced and supports its claims with a white paper on its ingredients and mechanism of action.

Overall, Blade Fat Burner is worth trying, but you should be watchful for side effects.
