I’m obsessed with finding diet products that actually work. Let’s find out if Lipo-6 Black UC is one of them. We took an exhaustive look at ingredients, side effects, scientific research and customer service quality. Additionally, we drilled down hundreds of customer reviews and comments. Then, we condensed and summarized to give you the info you need.

What You Need to Know

First off, Lipo-6 Black UC is a fat burner containing caffeine, theobromine, citrus aurantium, yohimbine and rauwolscine. After taking two capsules per day, the supplement supposedly increases energy and helps with weight-loss. The small pills are considered a benefit.

The supplement was introduced by Nutrex Research in 2002 as a weight-loss supplement and appears to include some natural ingredients, a good start. The official website and online retailers sell the product. We like that it appears to be affordable and that we located some positive customer comments, but read on…

Side Effects – “Look Out!”

The first negative was Lipo-6 Black UC side effects. “There’s one thing that keeps coming up one year after the next,” said our Research Editor. “The name of a product often tells the dieter what to look for.”

“I hated the feeling this product gave me. My head would throb all day long so I stopped taking it,” said a customer.

“After 30 minutes I felt insane hot body. Sat on my chair and started feeling like I was floating up in air, out of body. Soon my hands and legs started shaking. Also my heartbeat went insane and I felt crazy short of breath,” commented a consumer.

FDA Warnings – “Concerning?”

In April of 2012 and 2015, Nutrex Research was contacted by the Food and Drug Administration due to supplements containing 4-Amino-2-Methylpentane Citrate. The products stated the ingredient was natural, but in actuality, it was synthetic.

Ineffective – “No Changes?”

Based on consumer comments on the web, Lipo-6 Black UC ingredients didn’t help with weight-loss. “Lipo 6 black did not help in losing weight. Started at 312 lbs. Started training with regular weights and cardio 4-5 times a month. Ballooned up to my heaviest to 336 lbs.,” reported a consumer.

“No effect for me. Note that I GO to the gym and eat healthy food. My weight still the same,” commented a user.

“Garbage: no fat burning effects, lose energy and appetite suppression after first week. Big waste of $$$ don’t waste yours,” said another.

According to our research, we’ve found that it only takes something small relating to a supplement, like ineffectiveness, to put a halt to long-term success. If Lipo-6 Black UC doesn’t help users lose weight, there are problems.

The Science – “Any Proof?”

The official website provides details relating to the benefits of the supplement, but doesn’t offer links to published clinical research supporting weight-loss claims. We’ve found science-based facts linking caffeine to users losing weight, but nothing specific to this product. At DietSpotlight, science is a critical part of the research process. If Lipo-6 Black UC isn’t backed by studies, we have problems with it.

The Bottom Line – Does Lipo-6 Black UC Work?

So, the decision you’ve been waiting for: does Lipo-6 Black UC work? Well, we like that we located some positive customer comments and the length of time the company has been operating, but we have reservations about it due to the lack of published clinical research supporting the weight-loss claims. We’re also hesitant about it due to the reports of negative side effects, the ineffectiveness and the FDA warnings.

If you want to drop those extra pounds, we suggest going with a supplement containing a formula backed by published scientific research and no reports of negative side effects.

Among the best products we’ve encountered in 2016 is one called Leptigen. The supplement contains a formula consisting of a four-ingredient proprietary blend, which has been shown to help accelerate metabolism and jump start fat loss. People are commenting on the web about seeing excellent results and no one is talking about negative side effects.

Also, the makers of Leptigen are so confident in their supplement, they’re offering customers a Special Trial Offer, a great choice.

What You Should Know

Lipo 6 Black is manufactured by Nutrex, but the company does not list the product on the official website. The bottle label warns that the product is extreme and should be taken with caution due to the strong potency. Usually, this means the supplement is packed full of stimulants erring on the side of unhealthy, but maybe Nutrex found the Holy Grail of weight loss and that is the reason for the warning.

List of Ingredients

Beyond Extreme Fat Loss and Energy Igniter: Advantra Citrus Aurantium (60% Synephrine), Geranium Surge (1,3 Dimethylamylamine HCL) and Zingerone.

UNDERGROUND Fat Oxidation Stimulator: 3,5 Diiodo-L-Thyronine.

Lipolytic Acceleration Matrix: Yohimbine HCL, Yohimbe and Alpha-Yohimbine (as part of Yohimbe).

Metabolic Heat & Thermogenic Activator: B-Phenylethylamine HCL, N-Methyl-B-Phenylethylamine HCL and R-Beta-Methylphenylethylamine HCL.

Free Fatty Acid Releasing Complex: Caffeine Anhydrous, 1-Methyl Caffeine

Product Features

Unfortunately, Lipo 6 Black is not the Holy Grail and that is probably why the supplement is not listed on the Nutrex website. The Beyond Extreme Fat Loss and Energy Igniter is a dangerous combination of stimulants including Advantra with Citrus Aurantium and 1,3 Dimethylamylamine HCL. Zingerone is a derivative of ginger with very little information online.

Moving on to the Underground matrix we have more stimulants as 3,5 Diiodo-L-Thyronine has been proven to increase fat loss in rats. The Lipolytic Acceleration Matrix adds even more stimulants. All three Yohimbine ingredients will increase heart rate.

B-Phenylethylamine and the other similar ingredients in the heat and thermogenic activator are listed as mood enhancers in most online information. There is some information that they have a stimulant effect in the body. The final ingredients are caffeine and we all know they increase heart rate.

After looking at every ingredient in Lipo-6 Black, we found nothing but stimulants. Taking this supplement could be life threatening for someone sensitive to caffeine. Even the most hardcore dieter will feel jitters and shakes from taking Lipo-6 Black. The product sells for less than $30 on third party websites.


  • None.


  • Too many stimulants.
  • Could cause health problems.
  • May cause serious side effects for some dieters.


Lipo-6 Black is one of the scariest supplements we have reviewed to date. Every ingredient works in the body to increase heart rate. Dieters with heart problems could suffer from very serious side effects if they chose to take Lipo-6 Black. In all honesty, we love to review all products with an open mind, but Lipo-6 Black is not a product we would suggest to any dieter, no matter how much weight they had to lose.

Stimulants have their place in weight loss supplements, as a matter of fact, they are essential. Green tea and caffeine are two of our favorites, but only in doses low (or high) enough to be effective.
