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

Blade Fat Burning supplements form Blue Star fall in the latter category. These workout supplement pills are meant 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 strongest fat burning supplement designed specifically for men. They also claim that all of the product’s key ingredients have been clinically verified to be safe and effective.  

There are many fat burning workout supplements on the market, such as Skald and Animal Cuts. Workout supplement manufacturers make all kinds of 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. So today we are going to cover Blue Star’s Blade fat burning supplement and talk about its pros, cons, cost, where to find it, and whether or not you should bother buying. 

NOTE: We currently recommend Skald over Blade Fat Burner. Here’s why

Overview: Blade Fat Burners

Blade Fat Burning Supplements Bottle

Blade Fat Burners are designed to help men burn fat quickly. Blade claims to be made from an “award-winning formula” and claims to be stronger than any other fat burning supplement on the market. The bottle says that the product promotes “24-hour” fat burning so it ensures your body is working around the clock to boost metabolism. 

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 Stars claim, if true, puts it a leg above the competition. Many companies claim this though, so just because they say so does not make it true. 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. Blade 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 desired energy levels.  


  • Provides energy for more efficient exercise
  • Engage lipolysis to burn fat
  • Increases body heat generation to burn fat
  • Regulates appetite


  • Stimulant can be harsh in high doses
  • Yohimbine may be dangerous
  • Can interact with medications for heart or blood pressure problems

Who Makes Blade Fat Burners?

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 their products. According to their website, all of their products were designed and verified via human-testing, a bold claim if true. They say that each product goes through over 1,000 of hours of research before manufacturing and that they refuse to sell a product unless there is proof that it works. Blue Star claims they have this proof, but we were unable to find any links to clinical studies verifying the effectiveness of their products. It does seem odd that they make such a big deal about proof and evidence but don’t clearly provide said proof and evidence. 

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.

Ingredients In Blade

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

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

Green tea and caffeine are both common stimulates, they 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 a lot of fat burner supplements. However, both bitter orange and yohimbine have some problems. Both substances 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. 

Is Blade Fat Burner Safe?

Blade Fat Burning Supplement Effects

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. More importantly, the caffeine can have a negative interaction with yohimbine and bitter orange, which leads to low blood pressure, fatigue, and, in serious cases, fainting and loss of consciousness. We recommend being extremely careful when taking any supplement that combines these ingredients. 

Where to Buy Blade Fat Burner


You can buy Blade directly from Blue Star’s website or from third-party retailers like Amazon. Their website says you can buy Blade is select physical retailers, but does not provide a list of those stores. A 120-capsule canister of Blade costs $69.99

Blade Fat Burners: Worth It or Not?

We say yes but with one important caveat. 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 negative effects.
