We’ve heard a lot of buzz 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 numerous dieter comments and user responses from around the web. Lastly, we condensed all the facts and feedback to give you the info you need.

[1] [2] The supplement promotes weight-loss by suppressing appetite, increasing energy and enhancing mood. Once scoop of the powder is added to water and consumed before a workout or any time during the day.

High Price – “Yikes?”

The first issue that sprung up with D-Fine 8 ingredients was the impact on your wallet. “The actual cost of D-Fine 8 is $54.99 per container and this is for 30 servings. If you consume two per day, it will only last you for slightly more than two weeks. This means the supplement 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.

Side Effects – “Watch Out!”

According to customer comments about D-Fine 8 side effects, the fact that it contains citrus aurantium, which works like ephedra is concerning. 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.” [3]

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!!!” [4]

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 a sketchy formula that causes adverse effects in a lot of people, this could be a major concern. [5]

The Science – “Legit?”

At DietSpotlight, we need to see published science that backs the 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 supplement. That leaves us with no reason to give this one the green light.

What Users Are Saying

"Helps with water retention which is always a plus. And maybe it’s in my head but I feel like I’m in a better mood than normal."

"Steady long lasting energy without the crash."

"I wish they would bring back the old flavor. I’m on to finding the next best thing."

The Bottom Line – Does D-Fine 8 Work?

So, are you jumping in the car to race out for this one? Well, we like that it contains a few natural ingredients and that we found some positive customer comments. When we couldn’t locate any research connecting D-Fine 8 ingredients to weight-loss, we became concerned. Also, we’re skeptical about it because of customer complaints about negative side effects and the high price.

If you want to see faster results and ignite fat loss, we recommend you try a weight-loss supplement that contains safe ingredients, is supported by solid clinical research and offers customers bang for their buck.

Among the best products we’ve seen this year is one called Dietspotlight Burn. This supplement contains a unique blend of four key ingredients, which have been proven in documented scientific research to help 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 Dietspotlight Burn are so confident in their product they’re offering a special trial offer, which is a good sign.

What You Should Know

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 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!

    • Hayley

      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.

    • Maribel (Editor)

      Sorry about the side-effect you’ve been experiencing. Other users have reported feeling a headache as well. Try another product. Dietspotlight Burn is a good alternative…backed by clinical studies and positive consumer reviews.
