Xenadrine NRG 8 Hour Review

Cytodyne Xenadrine NRG 8 Hour

Long after the discontinuation of the original flagship product Xenadrine RFA-1, Cytodyne Technologies finally came out with a new energy boosting and fat burning product called Xenadrine NRG 8 Hour Power. With the FDA ban of ephedra and all ephedrine based fat burners, some of the most effective diet pills has been pulled off the market. With the weight loss industry being a multi-billion dollar industry, you can imagine the loss in sales for manufacturers. It would be my guess that Xenadrine NRG 8 Hour was formulated to make up for some of that lost sales. ;-)

Cytodyne calls Xenadrine NRG as the "next generation in energy and weight loss products", and "new 8-hour Power Xenadrine-NRG is a revolutionary new extended-release energy supplement... and then keep on working to maintain those levels for up to 8 full hours." It claims to take effect within just 30minutes, and will last for up to 8 hours - hence the name "Xenadrine NRG 8 Hour Power".

So does Xenadrine NRG really work and what does actual users say about it? Let's find out. First, we take a look at the ingredients.

Xenadrine NRG 8 Hour Ingredients

At first glance, Xenadrine NRG 8 Hour Power looks like a pretty standard lineup of ingredients - you got your caffeine, green tea, tyrosine, etc...  What cytodyne dubs as a "perfect ratio of herbs, amino acids, and vitamins." At a closer look, I see an unfamiliar ingredient called Norambrolide. Curious what it is and what it does, I did some digging.

Norambrolide - this is also called "fermented Salvia sclarea leaf extract". Ahh... now it doesn't look so unfamiliar after all!

Salvia Sclarea, is a potent adenylate cyclase activator - meaning that it increases the enzyme action of forming cylic AMP (cAMP - cyclic adenosine monophosphate) from ATP. What's the deal with cAMP? Increased cAMP increases lipolysis - or the breakdown of fat.

How does this new ingredient Norambrolide compared with ephedra? First, they have completely different mechanism of action, and second, I tend to think it'll be a pretty big miracle if the weight loss industry can really come up with something new & legal, that's as effective as ephedra. Honestly, I couldn't find any research done on this ingredient called Norambrolide and its effectiveness on weight loss... Regardless, Salvia Sclarea shows some promise, but we'll have to take a wait and see attitude. ;-)

Other Xenadrine NRG ingredients:

1) l-tyrosine: tyrosine is an amino acid that is a precursor for a number of neurotransmitters related to our feeling and mood. A deficiency in this results in depression and reduced ability to cope with stress, so with Xenadrine NRG you may get a lift in your mood.

2) Green tea extract helps to increase energy expenditure, thus helping with weight loss.

3) Yerba Mate: This herb contain a gentle form of caffeine, it also supplies vitamins, minerals, and 15 amino acids. Research suggests that yerba mate may aid with sleep irregularities and joint pains. Many people drink yerba mate to boost energy without the side effects of coffee. Besides this, there are other caffeine ingredients like guarana, and green coffee bean extract.

Does Xenadrine NRG 8 Hour Work - Feedback?

I constantly receive feedback on all types of supplements and fat burners from users like yourself, and I post (and update) user feedbacks constantly at our user feedback site here. So far, I have received some feedback on Xenadrine NRG, and as expected, its a mixed bag of 'reviews' - some seem to really, really like Xenadrine NRG for its weight loss and energy boosting effects, and others are not so positive on its effectiveness. But one common thing I find in most of these feedback is that most users noticed a boost in energy after about 20 to 30 minutes of taking the diet pills.

(PS. if you've used this, please send in your feedback as well. Thanks!)

Xenadrine NRG Side Effects

As with all fat burners, different users will experience different side effects - some worse than others, and some will experience no side effects. The only way to truly find out is by trying it out. Some side effects include:

  • Massive energy boost within 30 minutes of taking the pills
  • Anxiety, shaking, and light headedness
  • Cramps, numbness, light headaches, feeling faint
  • Increased heart rate and a rapid heart beat
  • Increased sweating and the need for more water
  • Nausea and upset stomachs
  • Suppressed appetite
  • Can be addicting

A quick note about the energy boost and addictiveness. The energy boost is like a double edged sword - many users seem to find that Xenadrine NRG 8 Hour can be addicting, mainly because of the energy boost, but its because of this energy boost, that they also have a tough time going off these diet pills.

Just keep in mind that during the first week, take just half the recommended dose, and go from there.
