D-Fine8 Zero Sugar By Musclewerks Review

One of the very few fat burners around at the moment that offer a totally sugar-free blend. Which makes it perfect to anyone sensitive to sugar, or for those hardcore athletes that want to get shredded. 

They claim it’s one of the best tasting fat burners available and helps provide energy without the crash. 

On their website, they say it’s been used by professional athletes all the way to the average person who doesn’t go to the gym. It looks like an all rounder! 

Let’s have a closer look and see if it’s the right fat burner for you. 


  • Fat Burning
  • Energy
  • Focus
  • Weight Management
  • Appetite Control 

Musclewrecksinc claim “DeFine8 is also known as the #1 best tasting powdered thermogenic.”

That may be the case, but is it effective? 

Having a look through the ingredients list it will be sure to promote all of the 5 benefits that they claim it to do. However, it’s approach is a little suspect. 

No1, it contains a proprietary blend so we’ll never know how much appetite control, energy, or fat burning substances we will be taking in each serving. 

Not only that, it contains some harsh ingredients such as Bitter Orange Extract which mixes badly with caffeine products such as Green Tea. 

“In traditional Chinese and Indian medicine, practitioners used green tea as a stimulant, a diuretic (to help rid the body of excess fluid), an astringent (to control bleeding and help heal wounds), and to improve heart health.” – University Of Maryland Medical Centre 

Study: Green Tea Benefits –

Needless to say, it’s not totally bad, it could work for some people who aren’t too bothered about which supplements they take. But for myself, even if I’m not sticking to a structured weight loss plan or workout schedule, I like to know how much I’m taking and what I’m taking. 

For me, it’s always quality over quantity.

A Closer Look – What’s Inside

Niacin:  Is basically a B3 vitamin and has been reported to improve the levels of good cholesterol in the body along with lowering the risk of cardiovascular issues 

Vitamin B6: B6 is increasingly important for optimal brain functioning and overall good general health. It also helps to regulate hormones within the body. 

Vitamin B12: B12 helps to increase natural energy levels for people suffering with fatigue or tiredness. It also works as other B vitamins in providing hormonal balances and optimal health.  

Pantothenic Acid: Another B vitamin, this time, it’s B5, Pantothenic Acid has been said to reduce lactic acid build-up during intense exercise. 

Proprietary Body Defining Blend: As you’ll probably already know, a proprietary blend basically means a cocktail of ingredients, i.e. we’ll never know how much is in each serving. With a lot of ingredients in this fat burning cocktail, I’ve selected the main ingredients that are of most important to fat burning to be examined:

CLA Complex (Conjugated Linoleic Acid): CLA is now being widely used in fat loss supplements as it’s claimed to break up fatty acids in the body and use them for energy. 

Green Tea Extract (leaf): One of the main players in fat loss supplements, Green Tea are full of catechins which release the fat burning hormone norepinephrine. Green Tea is possible my no1 pick as a fat burning ingredient.

Synephrine (from Bitter Orange Extract):

Guarana Extract: Another rich caffeine source, great for energy in your workouts, but potentially dangerous when mixed with Synephrine.

Side Effects?

Some of the ingredients could cause high blood pressure and possible headaches. This is down to the Synephrine. 

It could also cause nausea, stomach pains, and heart palpitation by mixing Bitter Orange extract and caffeine together. 


  • Zero Sugar Contains no sugar
  • Plenty of good B vitamins 
  • Uses Green Tea and CLA for added fat burning


  • Contains A proprietary blend of ingredients
  • Comes in a powdered form making it difficult to measure and take effectively
  • Mixing ingredients such as Guarana and Green Tea with Synephrine have proven to be dangerous for some individuals 

How To Use

It’s advised to take 1 scoop and mix with 8oz cold water.

Take once in the morning, and again once in the afternoon. (take 15 minutes prior to workout.) Do not exceed 2 full scoops per day.

Where Can I Buy It?

You can buy it from or other online stores such as and other online retailers that ship worldwide. 

How Much Does It Cost?

It costs $54.99 for 30 servings. 

My Verdict

This fat burner has some great ingredients, such as Green Tea, CLA, and a wide variety of B vitamins. However, it contains a proprietary blend, and as we know, this means we’ll never know how much we’re going to get of each ingredient. 

This isn’t an issue for herbal supplements, but, for a fat burner which contains aggressive substances such as Bitter Orange Extract that mixes badly with caffeine such as Green Tea and Guarana, I can honestly say this supplement isn’t for me. 

One of the best supplements I’ve seen that uses Green Tea and loads of natural ingredients is the in the Instant Knockout Review. 

On the whole, D-Fine8 Zero looks like a good contender when glancing through its benefits, however, it has used aggressive ingredients to promote fat loss. Perhaps one day Muscle rocks will change their approach.
