Zantrex-3 comes right out of the gate with boastful claims that it's not just another diet supplement in an already crowded market. Zantrex-3 says it belongs in a brand new category of super-charged, super-result supplements. Promising users up to five times the normal weight loss from other pills, and the energy you need, Zantrex-3 says it’s the fat burning, energy boosting pill that is going to win you over once and for all.

Zantrex-3 does come across as a high-intensity product that seems to focus more on the short-term rather than support for the long-term. You'll take Zantrex-3 about half an hour before each main meal - this will limit your appetite and you'll begin to see results in a couple of weeks.

Zantrex-3 contains three herbs that are not common, and there has been little research conducted - liex paraguarensis, turnera diffusa and Paulina cupana P.

  • Rapid weight loss
  • Lose more weight than with diet and exercise alone
  • Increased energy
  • Increase metabolism
  • Does not use ephedrine

  • No emphasis on diet and exercise
  • Xanthine
  • Guarana
  • Niacin
  • Green Tea
  • Ginseng

For maximum results, you should take two tablets 15-30 minutes before meals with a full glass of water. You should not exceed six capsules per day.


No guidance given.


There are, of course, many dietary supplements on the market that make similar claims. The decision to choose one of these over another should be an educated one. So, you should enlist the advice of your doctor. Supplements should not be relied on as a stand-alone weight loss plan, as a healthy diet and routine exercise greatly impact results. Zantrex-3 explains on its site that the product has not been tested alongside any diet or exercise programs.

I started taking Zantrex 3 last year and it really worked for me. Its the only diet pill that ever has. I have a couple of events coming up that I want to look good for, and I intend to start taking it again.

People may say whatever negative things they want about Zantrex 3. Personally, It has been totally effective for me and, when I need to drop weight, its what I turn to!

It definately gives me energy, however it does take it awhile to start working, I would reccommend taking your first dose very early in the morning.

So I started Zantrex 1 week ago. I started with one pill and am now up to 3 a day. If I didn't know any better, I'd say these are placebo pills. I haven't felt one thing! ZERO energy boost, ZERO side effects and ZERO weight loss. I'll stick with it one more week but something tells me this "rapid weight loss" gimmick is a crock! On to the next one.

Satisfied Customer

I've been taking this now for 4 days and I've lost 6 pounds already! I'm ONLY taking two a day, and I space them out one at breakfast and one at lunch. Keep in mind I've also switched to drinking only water instead of diet drinks with caffeine, and I'm also watching portion control, but still, i think they are great. I don't experience ANY nausea, no rapid heat rate, none of that. I think in combination with a healty diet you can really be successful using this pill.

So far its working i've been taking it for 2 days and lost 4 lbs. i weigh 141. 5 ft 1/2 inch. i only eat 2-3 small meals (nothing more than 500 cals. a day) and drinking nothing but water. I take 2 before lunch and 2 before dinner. it has been making me feel irritated and having a slight headache. but in the end its woth it.

I'm doing cross country and have been trying to lose about 10 lbs before districts. This pill gave me the extra boost I needed before practice and has curbed my appetite so much! So far lost 5 lbs in a week and times have gotten faster. IT WORKS!!!
