xantrex 3 blue bottle reviewLike alot of Americans, I want to lose weight.

And I don’t want to exercise or eat healthy, I just want to take a magic pill that just sheds the weight away.

Of course we all know that this is not possible, but it never hurts to dream right?

Well, when I came across Zantrex 3 in Walgreen’s, and they actually say you can lose weight without doing anything!

You probably thinking their is a catch, but there isn’t, they actually have done a clinical study on their product to show its effectiveness at burning fat without exercise or diet.

What is Zantrex 3 Blue Bottle?

Marketed as a rapid weight loss formula, Zantrex 3 promises to give you extreme energy and help with weight loss.

According to a study published on their official site and on the label, Zantrex 3users saw an average weight loss of 546% more than “Americas #1 selling ephedra based pill”.

They don’t actually state what that pill is and when we tried to get more information on this clinical study on their website, their was no information listed.

See our Comparison Between Zantrex 3 Blue Bottle Vs. Red Bottle

While Zantrex 3 does a good job of selling and marketing their product, it hasn’t come without a price.

Doctors have weighed in on the potential dangers and side effects from taking a supplement such as Zantrex 3, which is not subject to FDA scrutiny (similar to all other OTC supplements).

They caution that taking a product like this may have hidden consequences which could be detrimental to your health, even frowning on reality TV star “Snooki’s” endorsement of it.

But of course they’re going to say that, they’re doctors for crying out loud!

So the bottom line is you want to know whether or not it works.

We took a look through several other weight loss review sites, and poured through discussion and forums to see the results other users were getting before we decided to take our shot at it.

The majority of users that I came across were getting some small side effects from Zantrex 3, most notably headache, trouble sleeping, and flushed skin.

My guess as to what’s causing these side effects would be because it contains the stimulants caffeine and yerba mate.

Ingredients in Zantrex 3

Zantrex 3 Blue bottle works through a combination of proprietary ingredients, split up into 2 categories; weight loss and energy.

The ingredients you should be concerned with for weight loss include:

  • Yerba Mate
  • Guarana
  • and Damiana

and the ingredients listed for energy are:

  • Trimethylxanthine (fancy word for caffeine)
  • Guarana Extract

Their are about 24 other ingredients listed in Zantrex 3, but these are the primary ones used.

The full ingredient list includes:  Green Tea Extract, Kola, Schizonepeta, Black Pepper Extract, Rhodiola Crenulata, Asian Ginseng, Maca Root, Cacao Seed, and Black Tea Extract.

Their are some others listed, but they are mainly fillers and additives for coloring and product freshness.

My Results From Taking Zantrex 3

I’m not really a big guy to begin with, but I could definitely stand to lose about 15 pounds.

I’m already active, but my diet sucks, so I needed to stay off of the pizza and beer for a few days to not skew the results.

The dosage instructions on the Zantrex 3 blue bottle say to take 2 capsules, but I always like to start off with just one or 1/2 the dose to see how my body responds.

It’s a good thing I did that because after about an hour I started to feel the same side effects that were mentioned from the other users.

I think for me though, the side effects started to wear off kind of quickly, because i didn’t feel it for more than an hour or so.

I did feel a tremendous sense of energy, almost as though I could run a 5 k with no problem at all.

After taking the Zantrex 3 blue bottle for about a week, I noticed that I dropped about 5 pounds, and the side effects were non-existent.

Over time, I think that the effectiveness starts to wear off, but it definitely works to give you a big kick in the butt to get you motivated to work out.


Zantrex 3 is cheap enough to try out, without worrying about breaking the bank.

I got it for just $20 at Walmart, and it’s actually one of the cheapest weight loss pills you can buy there.

When compared to some of the other ephedra based fat burners I have tried, I think it works better than most.

It seems like most of the people that did not get any good results from taking it did not combine it with any diet and exercise, which is obviously crucial to anyone who is looking to lose weight over the long term, and keep it off.

By the way, the makers of Zantrex 3 also came out with a different formula which is supposed to be more potent than the original blue bottle, check out our review of that one here.

So about 2 days ago I started taking the blue bottle I currently and 5'4 and weigh about 170 I used to weigh 135 and would love to get back there.I gained the freshman 15 and then some.


I did a lot of research on this am here are some things I have learned.The red bottles have ephedrine in it and the blue don't.


The FDA doesn't approve weight loss pills with that in there.So if your taking the red ones just be careful.


Also the red ones are for people who athletes or work out a lot so if you are taking the red and just sit down on the couch or at a desk all day the red ones arnt for you.I am an athlete but I don't want to put the ephedrine in my body so I have taken the blue ones.


I haven't really had any side effects and here's why.I drink a lot of water when I take it and I make sure I dont immediately sit on my butt after I go for a little walk or go to the gym.


These pills are supposed to give you energy to do stuff and move around, so move a little.The people that see the best results are the ones who move around even a walk or something small.


The pills have made me more hungry but that is because it increases metabolism.So to curve that I drink more water and i have noticed i have been eating smaller portions because i get fuller feelings sooner.


In 2 days I have lost 2 pounds.And so my recommendations are
1. Don't take the red unless you are active (I am an athlete and I don't even take them)
2. If you take them drink plenty of water (makes sure you won't feel dizzy)
3. Move! (Right after you take the pills don't just sit down move around a little it'll keep you from feeling nauseous)
4. The burning feeling will subside, make sure you drink plenty if fluids!)
5. Avoid sugary things! Candy! Any thing that is supposed to help you lose weight doesn't work well with sugar and fats.


Always consult a doctor especially if you are taking other medicines or on other weight lose pills (that's dangerous!)

Ill keep you updated on my progress good luck all!

I took the blue bottle and had very good results even though I did not take them as recommended.The most I ever took was 3 a day but still lost about 60 lbs over a couple months.


I did experience the side effects but only initially til my body adjusted to taking them.The did lose their effectiveness after a while though.


I did not regain the weight after taking them either.I have tried several others with no results.


I am planning on beginning them again now that I have been off of them for a while..I also tried the red bottle for about a month but did not like them at all.

Hi, I've been taking the red bottle for about a month.At first it gave me really bad side effects for a week and now it's fine.


I haven't seen any results but it does give me energy, which I love.Today I purchased the blue bottle and I won't be using the red one anymore since everyone says blue works better.


How long should I wait to switch over to blue?Will it be ok if I start using it tomorrow?


I took one red one early this morning.

Rob Miller: Hey Tim,
It shouldn’t be a problem to switch the next day, but I would advise you to err on the side of safety, and wait 2 or 3 days before taking the Blue.
