Zantrex Black is a controversial weight loss supplement produced in America by Zoller Labs. The present “Black” formulation has been designed to replace the previous two products Zantrex 3 (in a red bottle) and Zantrex Blue (blue bottle). Both products acquired a reputation for causing side effects and the latest incarnation is fast acquiring a reputation that is equally black in nature.
Advertised benefits include:
- New Accelerated Rapid Release Formula
- Maximum Potency Liquid-Filled Softgel
- High Velocity Weight Loss
- Extreme energy… Fast
However the claims about high velocity weight loss and extreme energy are printed alongside a star, and customers who delve deeper into the reason for the star will discover the promised results are also dependent on “a sensible diet and exercise program” and that “individual results will vary”.
How the Formulation Works
Like its predecessors, Zantrex Black has been designed to work as a combined fat burner, appetite suppressant, and energy provider. If the formulation can live up to the promises made for it the capsules should help users to control their eating tendencies and consume fewer calories each day while also encouraging the body to begin burning its stores of body fat. The fat burning process can often provide an energy boost, but the formulation also contains several sources of caffeine.
Caffeine is usually tolerated well by most people, but overly high doses can cause unpleasant side effects and the manufactures admit each dose provides 300mg of stimulants. That is a lot more than many competing blends, so the fact that so many side effects have been reported is not at all surprising.
Key Ingredients and Blend Potential
Two softgel capsules provide 30mg of Niacin (vitamin B3) and 1,160mg of a proprietary blend.
Niacin is known to be beneficial for the metabolism, but also increases blood flow and may cause a warm sensation to the skin that is often known as the Niacin flush. While this is not in any way dangerous, and some people even find it quite pleasant, the feeling can be a little unnerving for anyone who does not know what to expect.
The Zantrex 3 A Proprietary Blend Contains:
- Yerba Mate (leaf) Extract
- Guarana (seed) Extract
- Damiana (Turnera diffusa var. aphrodisiaca) (leaf) Extract
- Green Tea (leaf) Extract
- Kola (seed) Extract
- Schizonepeta (flower) Extract
- Black Pepper (fruit) Extract
- Rhodiola crenulata (root) Extract
- Asian Ginseng (root) Extract
- Maca (root) Extract
- Cacao (seed) Extract
- Black Tea (leaf) Extract
The lack of inclusion rates makes it hard to predict how well the formulation is likely to work, but green tea stands out as being one of the better blend additions. It has a good reputation as a fat burner and its effects can be enhanced when it is blended with caffeine, as is the case here, but with 6 caffeine sources included in the blend (yerba mate, guarana, trimethylxanthine, kola, cacao, and black tea), the amount of stimulation provided is unnecessarily high. Black pepper is a valuable inclusion because it is a natural fat burner, but it also aids the absorption of other ingredients and with so much caffeine in the mix that can only increase the chances of side effects.
A few customers state the product works.
But an alarming number of customers report experiencing unpleasant side effects. A few sample comments read:
Side Effects & Health Issues
The manufacturers warn against using the product alongside other caffeine sources to limit the likelihood of nervousness, irritability, sleeplessness and rapid heartbeat. They also state the product should not be used alongside or as a substitute for any of their previous Zantrex products because the formulation contains “significantly potent” stimulants (about 300mg per serving).
The product is also unsuitable for people who are sensitive to niacin, pregnant or nursing mothers and people under 18-years of age. People who are taking medications or have existing health issues are advised to seek medical advice before using Zantrex Black.
Purchasing Options & Considerations
Although it is sometimes possible to purchase via Amazon it is usually easier to purchase Zantrex Black directly from the manufacturer. Each bottle contains 84 softgel capsules and has a price tag of $39.99. Customers who opt to sign up for a “VIP Subscription” (automated billing and shipping) secure a saving of $8 per bottle and benefit from free shipping.
A 30 day money back guarantee is offered.
The Bottom Line
Zantrex Black is very much a caffeine-driven blend and the overly generous amount provided easily explains why so many customers report experiencing frightening side effects such as racing heart rates. It is probable that some users may gain some degree of appetite suppression, and fat burning may also be triggered. But as a whole the formulation does not possess the potential of many competing blends, and any good points are far outweighed by the bad, so we are unable to approve the use of Zantrex Black as a weight loss provider.
Alternative That We Recommend
It’s hard to recommend anything other than PhenQ in the fat burner category.
PhenQ has been available to buy without prescription for a few years now and has become the best selling fat burner / appetite suppressant in the UK, United States, Canada and Australia as well as several other European countries.
