Zantrex-3 is a brand of sports nutrition supplements by Zoller Laboratories. Two products in particular bear the Zantrex-3 name: Zantrex-3 Fat Burner and Zantrex-3 Weight Loss. The former comes in a red bottle, the latter in a blue bottle. As their names suggest, both products are fat/weight management supplements, offering the benefits of boosting energy, metabolism and mental focus while reducing fat, fatigue and hunger.

Both products deliver engineered weight management compounds in proprietary blends. While several key ingredients appear in both Zantrex-3 Fat Burner and Zantrex-3 Weight Loss, the products are different. Each contains its own specific stack. Each stack targets a particular set of biological activities that enable users to achieve fitness goals disclosed on the product packaging and on the Zantrex-3 website.

None of Zoller Laboratories’ claims about Zantrex-3 products enjoy the benefit of FDA evaluation, which is not uncommon in the sports nutrition industry. However, it’s helpful to understand distinctions between said claims.

For example, Zoller Laboratories claims that Zantrex-3 Fat Burner specifically supports fat burning with compounds that have proven thermogenic/lipotropic properties. Conversely, Zantrex-3 Weight Loss targets all around weight management, which potentially encompasses the loss of fat and muscle, as in extreme cutting phases prior to contest season.

Following is a concise appraisal of the ingredients in both products and their efficacy.

What’s in Zantrex-3 Red Fat Burner and Zantrex-3 Weight Loss?

The active ingredients in the proprietary blends of both products:

  • Guarana Seed Extract
  • Kola Seed Extract
  • Green Tea Leaf Extract

Each of the above extracts contains its own form of caffeine. When combined, they make for a powerful, potent source, delivering jolts of energy and heightened synaptic activity (brain activity/alertness.) Each extract also has its own unique set of secondary compounds that affect how your body absorbs caffeine.

The caffeine content in guarana seed extract is nearly twice as much as that in coffee beans. Guarana seeds contain organic substances called tannins. Tannins give wines their woody flavor notes. Tannins interact with caffeine in such a way that slows the body’s absorption, resulting in a natural time-release dose of energy.

Kola seed extract contains an approximate average of 1 to 2 percent caffeine per sample. Kola seed caffeine enjoys rather extensive circulation throughout the brain, thanks to one of its other compounds, an alkaloid that gives chocolate its pro-cerebral potential. The combination of both compounds creates a sense of euphoria in your head.

In addition to its own caffeine content, green tea extract is also rich in crystalline compounds called catechins. There are four main cetechins in green tea:

  • Epicatechin (EC): 6.4 percent
  • Epicatechin 3 gallate (ECG): 13.6 percent
  • Epigallocatechin (EGC): 19 percent
  • Epigallocatechin 3 gallate (EGCG): 59 percent

Studies and experiments show that caffeine combined with these catechins reduces cholesterol, fat absorption and appetite. In both products this stack helps to mobilize your fat stores, minimize your hunger pains and the absorption of fat from your diet.

Additional ingredients in Zantrex-3 Fat Burner:

  • Coffee bean Extract
  • Citrus Fruit Extract
  • Whole Plant Kelp Powder
  • Fennel Seed Powder
  • Alpha Lipioc Acid

Coffee bean extract simply supplies another form of caffeine that works synergistically with those already addressed in this review. The citrus fruit extract in Zantrex-3 Fat Burner is rich in alkaloids that increase energy, metabolism and caloric expenditure, causing you to burn more calories at an accelerated pace.

Whole plant kelp powder effectively supplies the nutrients you might not manage to ingest during cutting phases that require drastic reductions in caloric intake. Kelp contains fiber, high concentrations of iodine, iron, calcium, magnesium and potassium. Amino acids, phytonutrients, antioxidants and omega-3 fatty acids are other nutrients kelp contains.

Each nutrient positively affects an array of biological functions. The minerals double as electrolytes, enabling you to perform fuller muscle contractions without fatigue and to maintain optimal hydration levels. Omega fatty acids are anti-inflammatory and supply the basic material your body utilizes to repair cell membranes.

Recall that caloric restriction and intense exercise suppress your immune system and many other systems in the body. As a result, your nutrient requirements increase tremendously. The whole plant kelp powder provides additional source of key macro and micronutrients that help your body repair itself and stay strong during your complete fat burning regimen.

Similar to kelp, fennel seed powder alleviates inflammation when taken at critical dosages over time. Fennel is also a natural, gentle diuretic, so it relieves water retention. It helps you keep water weight down, which results in a leaner, more cut appearance.

Alpha lipoic acid is a powerful antioxidant that prevents free radical damage. Remember that free radicals are atoms with unpaired electrons. These unstable atoms reek havoc on your system, hastening the aging process and the decay of otherwise healthy tissue. Exercise, dieting and lipolysis (the breakdown of fat) generate free radicals.

The inclusion of alpha lipoic acid greatly lessens the effects of free radicals, keeping your body’s systems in optical condition for further exercising, dieting and lipolysis.

The other ingredients in Zantrex-3 Weight Loss:

  • Yerba Mate Leaf Extract
  • Black Tea Leaf Extract
  • Trimethylxanthine
  • Cacao Seed Extract
  • Maca Root Extract
  • Asian Ginseng Root Extract
  • Damiana (Turnera Diffusa var. Aphrodisiaca) Leaf Extract
  • Schizonepeta Flower Extract
  • Rhodiola Crenulata Root Extract
  • Black Pepper Fruit Extract

As with Zantrex-3 Fat Burner, Zantrex-3 Weight Loss contains an extensive caffeine stack. Extracts of yerba mate leaf, black tea leaf and cacao seed all supply various forms of caffeine. Trimethylxanthine is just the official name for pure caffeine. When stacked, these forms of caffeine enhance each ingredient’s effects on the body, such as promoting excitement, euphoria, accelerated metabolism and fat burning.

Asian ginseng root extract also energizes your mind and body while stabilizing blood sugar and reducing hunger pangs.

Damiana is a native Mexican herb. According to a 2001 Denmark study, damiana stacked with yerba mate and guarana constitutes a powerful thermogenic stack and appetite suppressant. Rhodiola crenulata is a natural adaptogen, a substance that enables your body to adapt, respond and thrive at times of great stress.

Rhodiola props up your mental focus, endurance and immune system over a long period, as in months, while you punish your body with Spartan dieting tactics and strenuous cardio. Lastly, black pepper is this product’s expediter, so to speak. Its active ingredient, piperine, enhances the absorption of nutrients and chemical compounds, delivering peek blood concentrations and corresponding benefits in less time.
