D-fine 8 Review - Does This Fat-Burner Powder Really Work? Are high price and dangerous ingredients deal breakers?

Editor's Review: 3.5 / 5.0

define-8We’ve heard a lot of chatter about D-Fine 8 supplement powder, so we took some time to create an in-depth review, scrutinizing the ingredients, side effects, customer-service quality and scientific studies. We additionally examined dozens of dieter comments and user responses from around the web. Lastly, we condensed all the facts and feedback to provide you with the info you need.

EDITOR'S TIP: Combine D-fine 8 with a proven fat burner such as Leptigen for better results.

What You Need To Know

D-Fine 8 is a fat-burning supplement available from MuscleWerks. This powder formula comes in 15 different flavors, and some of them are; cherry bomb, mango, green apple, strawberry, pink lemonade, pineapple, fruit punch, watermelon and bada bing cherry. The purpose of D-Fine 8 is to heighten energy levels, control appetite, burn off fat and enhance mood. This supplement is simply added to water and then consumed before a workout or any time during the day. The ingredients found in this powder include the following; Conjugated Linoleic Acid (CLA), Green Tea Extract (contains EGCG), Guarana Seed (contains caffeine), Cactus Leaf Extract, High Linoleic Adic (HLA from Safflower Oil), Dandelion Leaf Extract and Citrus Aurantium (contains Synephrine).

D-Fine 8 first emerged in 2011 and it comes in numerous flavors. This supplement is backed by some customer testimonials and it can be purchased through several online stores, but read on…

High Price – Yikes

“The actual cost of D-Fine 8 is $54.99 per container and this is 30 servings. If you consume two servings per day, a single container will only last you for 15 days. This means D-Fine 8 will end up costing you about $110 each month,” says our Research Editor.

One customer commented, “Definitely not cheap, don’t think I’ll buy again.”

“Not worth the $55 plus shipping!,” said another user.

Dangerous Ingredients – Watch Out!

This supplement contains Citrus Aurantium, which has Synephrine in it. As you may already know, Synephrine works like Ephedra. This is concerning because Ephedra was banned due to serious side effects. One customer revealed, “It gave me a consistent stomach ache each time I took the product. It really didn’t help with appetite control or energy levels.”

Another user said, “Taste is the worst! Gave me the most horrible heartburn, used as pre-workout and lasted the whole time, but I still had horrible heartburn the next day and could not stand it!!!”

According to our research, if there is a certain facet of a supplement or diet program that is very concerning or bothersome (a painful/difficult exercise routine, high price, dangerous ingredients) the odds of long-term success are not good. This means if D-Fine 8 does contain dangerous ingredients that cause adverse effects in a lot of people, this could be a major concern.

The Science

At DietSpotlight, we need to see published science that supports the diet product for weight loss. However, there was no documented clinical research or studies posted online to support D-Fine 8 as an effective fat burner and weight loss supplement. Therefore we cannot support this product.

The Bottom Line

It’s great to see that D-Fine 8 comes in so many different flavors. This is definitely something people like to see. On the other hand, this product contains Synephrine, which may lead to side effects. Also, it is quite pricey at $54.99 per jug. In the end, we do not recommend D-Fine 8 for serious fat loss.

If you want to see faster results and get rid of some serious body fat, we recommend you try a weight loss supplement that contains safe ingredients and is supported by solid clinical research.

One of the highest-rated diet products we’ve seen in 2015 is one called Leptigen. This supplement contains a unique blend of four key ingredients, which have been proven in documented scientific research to kick-start metabolism and improve overall fat loss. Also, we have not discovered any talk of harmful side effects and customer feedback posted online shows people are seeing substantial results.

Also, the makers of Leptigen are so confident in their product they’re offering a special trial offer, which is a good sign.

D-fine 8 is a product created by Muscle Werks which is a company under the Hans Drake International, Corp. The Hans Drake website appears to be less than functional at the time of this review with only small portions of the website working properly. Products are listed, but there is no information about the products. You can add products to your shopping cart, which is linked to PayPal, as well. D-fine 8 is a powered supplement available in 21 different flavors. In order to get a better idea what makes D-fine 8 by Muscle Werks burn more fat, we looked at third-party websites for a complete ingredient list.

List of Ingredients

Conjugated Linoleic Acid (CLA), Hoodia Gordonii, Synephrine, Caffeine (from Guarana Seed), Dandelion Leaf Extract, and Green Tea Extract.

Product Features

D-fine 8 jumps into weight loss with conjugated linoleic acid (CLA). This ingredient has been used for many years with supplement companies claiming it can reduce muscle loss during weight loss and even help build lean muscle. Some users complain the ingredient causes stomach upset. There is also no strong clinical data to back up the claims of building lean muscle mass. Hoodia Gordonii is another flash from the past. This appetite suppressant was the most popular ingredient just a few years ago until dieters and research groups found it did not suppress appetite. The portion of Hoodia that is supposed to fight hunger, P57, is metabolized too quickly by the body to offer any weight loss support. Synephrine is a name we are familiar with as is caffeine. Both are stimulants. We like caffeine in the right amounts, but synephrine could cause negative side effects in some users. As the cousin of Ephedra, synephrine is considered a “light” version of Ephedra but increase heart rate and blood pressure are common side effects. Dandelion Root Extract is not a weight loss ingredient at all. Instead, it is a diuretic. Diuretics cause urination and water weight loss, but the effect is temporary. The final ingredient is green tea extract – a proven ingredient with clinical backing for weight loss. We love the fact that D-fine 8 includes green tea, but would like to know how much green tea is included. The D-fine 8 powder retails for $64.99 and can be purchased from the Hans Drake website. We would not suggest buying the supplement from Hans Drake, because most of the website is not functioning, so the dieter may have to request a refund or investigation through Paypal if the order is never sent.

  • Green tea and caffeine are proven to increase weight loss.


  • No ingredient list on the official website.
  • Hans Drake website is not working properly.
  • All sales are made through Paypal instead of an integrated checkout page.
  • Synephrine could cause negative side effects.
  • Dandelion is a diuretic.


There is no reason why a dieter should take a chance on a weight loss supplement. Without any information about why the official website is not working, the dieter should steer clear of this company. D-fine 8 is not a proven weight loss product and does not contain enough proven ingredients to help the dieter achieve substantial weight loss.

    i love define-8 I find it really works, but it always seems to go clumpy and stick together I only get to use around half of the tub is there anything I can do to stop his ?



    Keep it in the fridge :)



    Shake the container every few days to prevent the product from sticking to each other.



    After opening, keep it in the fridge.

    I had been using dfine8 and found as soon as my heart rate raised I’d get a blinding headache… No more for me, it’s not worth risking my health for!



    I found this did the same to me however I decreased the amount reccomended for a few days and my headaches were decreasing. Now I use the reccommended (1 scoop) daily. Also if your body isnt use to drinking caffine that can have an inpact causing headaches.
