Oxy-Burn is a natural fat burner from Biothrive, which has whipped up a bit of a buzz on Amazon. Amazon can be a great place to buy supplements, but fair to say their reviewing system isn’t exactly fool proof.

Oxy Burn

That means before buying you’ve really got to investigate properly to find out if you’re dealing with real satisfied customers or a marketing department.

Or if all that sounds like too much work you could just let us do it for you then read this review.

Oxy-Burn makes has 2 simple aims: speed up metabolism and burn fat. Sounds ideal, except it does this by using 3 proprietary blends. That means no individual amounts for ingredients, just a mix and overall volume.

Knowing that individual doses are right is key, so this is frustrating, but let’s take a closer look anyway.

How Does It Work?

At a Glance

  • Green tea, Yohimbie & (supposedly) Rapberry Ketones to burn fat.
  • Caffeine, Acacia Rigadula & Synephrine to boost metabolism.
  • Phenylethylamine, Fursultiamine & Tyrosine to help energy and focus.

We’ll look at the pros and cons of these choice up close later after the overall scores…

The Scores

Oxy-Burn
Ingredients
33%

There are some serious problems with this formula. Even the good things like green tea and yohimbe have question marks over them because we don’t know the amount. And although there are possibly some good energy boosters here, the recent scandal over Acacia Rigidula and  issues with synephrine, make it a risky choice

Price
56%

Oxy-Burn is cheap, but there are times when you get what you pay for. Here you might not even get that. Given our above concerns we’re inclined to suggest that however much money their asking, it’s probably best saved.

Trustworthiness
32%

This supplement is made in the U.S so you would assume complies with GMC guidelines. But with the use of proprietary blends hiding exact doses and the FDA’s stance on Acacia Rigidula, credibility takes a hit.

Testimonials
47%

We’re left to rely largely on the questionable amazon review section for testimonials and even those are pretty split. They range from the suspiciously perfect too those reporting some of the side effects we warned about. Not exactly a vote of confidence.

Company
20%

We found it pretty hard to dig up any information on BioThrive apart from the fact that they’re based in California and that their products are GMP registered. This is not enough to give a rounded view of the company and is a real disappointment as disclosure is so valuable in this industry.

How Many Servings A Day?

Users take just a single serving a day to get the best out of Oxy-Burn.

We’re always suspicious when we hear this. One serving to burn fat for a whole day? That’s a bit of a stretch. 3-4 servings a day is what you should be looking for to keep active ingredients topped up and the effects ticking over.


What About Side Effects?

This is a real worry. If synephrine raises your blood pressure you could be at increased risk of heart attack or stroke. Some users have also reported sickness as a result of a synephrine and caffeine mix.

Too much yohimbe causes anxiety and stomach problems so you need to be careful there too.

Also if the FDA is warning that PEA in Acacia Rigidula is simmilar to amphetamine, we can’t rule out its side effects. Shaking, restlessness, headaches etc.


Where Can I Get Oxy-Burn?

Customers will find Oxy-Burn at Amazon for just under $20, which buys a month’s supply.

Anything Missing?

Overall

This burner is a case of the good, the bad and the possibly downright dangerous. It may be cheap, but most people use natural supplements so they don’t have to worry about what they’re taking.
