NutraBio Yohimbe is Back: Lab-Tested Inferno-Strength Fat Burning

NutraBio Yohimbe

NutraBio Yohimbe is back, and now it’s 100mg yielding 4mg yohimbine – perfect!

NutraBio, the company synonymous with fully disclosed open labels and third party tested nutritional supplements has recently added another single ingredient product to the company’s expansive line. The newly-released NutraBio Yohimbe Standardized Extract is technically a reformulation of NutraBio’s previous yohimbe bark product, which was a bit less flexible due to its extreme strength.

All too often, reformulations leave customers scratching their heads wondering why the product they love has been tinkered with, but in this case, we’re 100% on board. The updated yohimbe will allow for greater individual dosing freedom and limitless ability to stack with other supplements.

Once you see the new label and compare to the old label, you’ll see why. Now we have a full-spectrum yohimbe that we can trust, where we know each and every time how much yohimbine is going to come from it – and it’s a dose that most Y-lovers should be able to handle without problem. Yohimbine is great, but when we can get the entire spectrum of yohimbe, it really excites us!

The label’s below, but first, check out the coupon-powered prices and sign up for PricePlow’s NutraBio alerts, since the brand has more coming each month:

Yohimbe, the good…

Yohimbe bark is sourced from the African tree Pausinystalia johimbe tree found in various western and central African countries and is native to those areas. Yohimbe has enjoyed a long history of use in traditional medicine in these regions. Historically yohimbe has been used as an aphrodisiac, tonic, and stimulant.

Yohimbine: The active. 4mg per capsule here!

The main alkaloid in yohimbe commercial products is yohimbine. The majority of products on the market are standardized for it. Yohimbine in it’s pure synthetic hydrochloride form (yohimbine HCl) has been used for several purposes, most typically energy, fat loss, and appetite suppression. However, it’s even been used as an ED therapy (although that’s been replaced by the PDE-5 inhibiting drugs you see commercials for all the time).

NutraBio Yohimbe Ingredients

Finally, a well-dosed full-spectrum yohimbe that’s third-party lab tested!

NutraBio has standardized their new 100mg capsules of yohimbe for 4% yohimbine in 90 count bottles and you can count on the contents matching the label (more on this later).

Yohimbine’s benefits

Yohimbine’s popularity in modern times stems from its ability to increase fat loss, decrease appetite, improve male virility and provide stimulation.[1-3] Yohimbine acts on receptors within the body and provides its metabolic effects via antagonism, that is too say blocking the effects of, the alpha-2-adrenergic receptor. Alpha-2 receptors inhibit the release of norepinephrine and thus lower the amount of thermogenesis within the body. Think of alpha-2 receptors as one of the body’s off-switches for fat release and stimulation. By blocking the restrictive action of alpha-2 receptors, users will experience higher levels of norepinephrine, and thus arousal and alertness, vigilance, increase in quality of erections in men, formation and retrieval of memory, and an increase in lipolysis (fat burning)!

Yohimbine research

Yohimbine is not a new arrival to the supplement market and thus is an ingredient that is supported by a long history of use and modern research extolling its benefits. Researchers at the Institute of Sports Medicine, Sports Academy, Belgrade, Serbia and Montenegro studied the effects of yohimbine on a group of twenty professional soccer players. The fact that experienced athletes were used is a huge plus as it reduces the chance of any benefits being attributed to simply out of shape individuals beginning an exercise program.

Finally, a trusted yohimbe you can use to attack stubborn body fat!

In the study, each player was given a serious 20mg/day of yohimbine or a placebo with the yohimbine group dividing their dose into two 10mg doses per day for a total of 21 days. While the researchers did not observe any increase in performance, there was a significant increase in fat loss in the yohimbine group vs the placebo. The yohimbe group on average went from a 9.3% body fat down to 7.1%[1] – a 2.2% drop in overall body fat!

This amount of fat loss is phenomenal in such a short period of time, but note the high dose and high gear these athletes work in. Anyone who has ever managed to work their way down to sub 10% bodyfat can attest to how resistant the body (wisely) becomes to losing anymore fat. In addition to the positive effect on body composition, there were no reported side effects by the yohimbe subjects, something we’ll need to touch on below.

In addition to fat loss, yohimbe has been shown to decrease gastric emptying thus decreases appetite and caloric intake in obese subjects.[2]

As mentioned, yohimbe has a history of being used for its purported aphrodisiac properties. The purported benefits for male performance have been the subject of numerous studies. Seven of these studies deemed to be of the highest quality were analyzed by the Department of Complementary Medicine, Postgraduate Medical School, University of Exeter, United Kingdom. The researchers concluded:

“The benefit of yohimbine medication for erectile dysfunction seems to outweigh its risks. Therefore, yohimbine is believed to be a reasonable therapeutic option for erectile dysfunction that should be considered as initial pharmacological intervention.”[3]

Yohimbe, the “bad”…

The yohimbe alkaloid yohimbine is supported by modern research when it comes to fat loss,[1] appetite suppression,[2] and male performance,[3] so what’s the catch?

Like so many things in life there are positives and potential negatives. Yohimbine is a very polarizing ingredient. Many love the benefits while others will avoid any product containing it. Due to the alpha-2 inhibition some people may have a potential increase in anxiety, for instance as demonstrated when taking 0.4mg/kilogram of body weight.[4] That study’s effects equate to a very large dose of 33.6mg yohimbine for a 185lb man – but as many of us who are “y-sensitive” have seen – some will get anxious off of less than 10% of that dose!

Yohimbine Norepinephrine

Yohimbine increases norepinephrine levels,[6] and that is one reason why this is so intense!

It’s important to remember that this potential side effect applies to almost every stimulant to some degree or another and the dose used in the study on anxiety was well above the recommended dose by NutraBio and nearly twice that used in the fat loss research.

This is why it’s good to start with low doses and to understand whether or not you’re a “yohimbine hyper-responder”. It’s also why we’re very happy that NutraBio reformulated this, as they were formerly sporting a whopping 8mg yohimbine per capsule in the original 200mg yohimbe formula!! Far too strong for testing the waters out!

The research has shown that yohimbine has a respectable safety profile for normal healthy individuals. As is the case for any stimulant user with preexisting health issues, such as high blood pressure or heart disease, one should consult with their physician prior to supplementing. It is important to note that many products that contain yohimbe also contain one or more stimulants. It really is hard to blame yohimbine alone for a side effect when it is paired with exotic stimulants with little to no research performed on them. This simply is not a concern when using a pure single ingredient product such as NutraBio’s Yohimbe here.

Yohimbe, the ugly… and where NutraBio saves the day

Got third-party lab testing? NutraBio does, and it’s more important than ever here. Here’s why:

In September 2015 Pieter A. Cohen and colleagues published the most detailed test of yohimbe supplements and their manufacturers meeting label claims.[5] The researchers randomly purchased 49 brands of yohimbe from seven supplement retailers. The bottles were analyzed for content and compared with the amounts claimed on the labels. After testing the researchers stated that only two brands accurately labeled their product and provided a satisfactory warning of potential side effects. Some of the bottles did not state what percent of yohimbine the yohimbe contained and others that did where off by as much as 147%! Other bottles tested had far less than the label stated — with as little as 24% of label claim![5] So in this case we have the user either getting far more stimulant that they desire or getting far less than they paid for.

NutraBio Protein Lab Test

More important than ever with yohimbe, NutraBio releases 3rd party lab tests for ALL of their supplements!

Not cool, and not going to happen at NutraBio.

Dr. Cohen’s findings are not the fault of yohimbe and are more indicative of poor industry manufacturing practices by those taking shortcuts in the name of laziness or profit margins. This analysis may also provide insight into why some feel so negatively towards yohimbe. If many products on the market are overdosed it would explain why some people are so “sensitive” to its effects. When you’re dealing with an ingredient that is effective at such low doses it does not take a significant amount to put you over the edge of effective into uncomfortable.

Third party lab tests to the rescue!

So what’s the solution? NutraBio’s third-party lab-testing. They not only test the raw materials as it comes into the factory… they not only test the finished product… they also send it to another lab that they don’t own and publish the lab tests live on their website!!

So if you’ve never tried a solo product like this, you may be missing out on an effective supplement that doesn’t break the bank. If you care about quality and honesty in labeling you can purchase NutraBio Yohimbe and rest assured you are supporting a company that is fanatical about quality and accurate labels – and they have the data publicly disclosed to prove it!

Dosing Freedom

Being the powerful compound it is, the ability to adjust one’s dose of yohimbe and yohimbine is essential. Many users find they can tolerate yohimbe perfectly fine when they are able to dial in the dose to match their personal tolerances. Yohimbe really is a product best suited to being sold as a solo ingredient.

When bought in a formula, usually proprietary, one often has no idea how much one is getting and has to reduce the serving size of everything in the product to find the sweet spot. A single ingredient yohimbe, such as NutraBio’s, dosed at a moderate 4mg of yohimbine per capsule solves this issue. Not too little (those 1.5mg caps get annoying for us Y-lovers), but not too much.

A solo yohimbe also allows you to add on to any other product you are currently taking to further ramp up fat loss and energy. With certain manufacturers choosing to leave out yohimbe due to international shipping concerns this may soon be the most popular way to consume this potent compound.

Most effective when taken before meals / on an empty stomach

Due to alpha-1 antagonism yohimbine is most effective when taken on an empty stomach. For those looking to squeeze every little bit of benefit out of their supplements dosing either during a fast or as far away from food as possible is advised.

Want solo yohimbine? NutraBio has that too

NutraBio Yohimbine HCl

Don’t want to go full-spectrum? Then straight 3mg yohimbine also available in NutraBio Yohimbine HCl!

Note that the brand also has the standardized NutraBio Yohimbine HCl, which brings less strength — 3mg per capsule — and does not have the “full spectrum” of additives that come with the stronger yohimbe extract we’re talking about here today. This is a great way to give you both options, but either way, you’re not going to find those weak little 1.5mg yohimbine capsules with NutraBio!!

But at the same time, we like today’s new yohimbe product here if looking for all of alkaloids, saponins, terpenes, etc that nature put in there to use together. This isn’t a scientific opinion, but it seems that things just work better when kept as part of their bigger whole, when possible.

Final thoughts… this is what was needed for “Y-lovers”

Yohimbe and its main alkaloid, yohimbine, are effective aids in one’s pursuit of a lean healthy physique. We have published research on humans supporting rapid fat loss, appetite suppression, and reduced erectile problems, but the problem has always been trust and quality — especially with these full-spectrum yohimbe extracts. Not anymore, thanks to the NutraBio way of doing things, third-party lab tests and all!

With NutraBio’s solo offering one can tailor the dose to meet their individual needs while being assured they are buying the highest quality natural yohimbe available – yohimbine doses disclosed and all.
