What is Lipo-6 Black UC?

First off, Lipo-6 Black UC (ultra concentrate) is a fat burner often confused with Lipo-6 Extreme Potency. The ingredients are caffeine, theobromine, citrus aurantium, yohimbine and rauwolscine. With just one pill per day, the supplement supposedly destroys fat.

Nutrex Research, the company behind Lipo-6 Black UC, started in 2002. The official website and online retailers sell the product. We like that it contains a few natural ingredients and that we located some positive customer comments, but read on…

Lipo-6 Black UC Side Effects – “Concerning?”

The first negative was Lipo-6 Black UC side effects. “We noticed that this one contains multiple stimulants,” said our Research Editor. “Unfortunately, there’s a chance that the combination could lead to adverse reactions.”

“My head would throb all day long, so I stopped taking it,” said a customer.

“After 30 minutes I felt insane hot body,” commented a consumer.

We did find some users that didn’t experience negative side effects.

“The only side effects was a boost in energy,” commented a user.

Ineffective – “Losing Weight?”

Based on dieter comments, Lipo-6 Black UC ingredients didn’t help with weight-loss. “Lipo 6 Extreme Potency did not help me lose weight,” reported a consumer.

“No effect for me. I hit the gym and eat healthy,” commented a user.

On the other hand, there are some reviews of Lipo-6 Black UC mentioning solid results.

“Weight-loss takes time. So I’ll stick with this one,” said a dieter.

“Lost a few pounds in a month,” mentioned another.

Our research shows a connection between a reduction in long-term success and a supplement being ineffective. There are problems if Lipo-6 Black UC doesn’t help users notice solid results.

The Science – “Any Proof?”

The official website provides details relating to the benefits of the supplement. But, there are no studies supporting the 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.

What Users Are Saying

"”I wish there is less than 1 star , I’m too upset about this product , doesn’t fat burn at all its just or maybe helps with energy . I not recommend it never !”"

"”Didn’t work as I was expecting but it takes away the appetite. Don’t worth.”"

"”Worked great for me! Increased energy and focus. Helped me power through my difficult workouts.”"

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 seen this year is one called Dietspotlight Burn. The supplement contains four- clinically-tested ingredients, 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 harmful side effects.

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

What You Should Know about Lipo 6 Black Extreme Potency

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 Lipo 6 Black Extreme Potency 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.

Advantages of Lipo 6 Black Extreme Potency

  • None.

Disadvantages of Lipo 6 Black Ultra Concentrate

  • 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.
