Phenolox Review - 5 Things You Need to Know


Metabolism boosters are flying off the shelves these days, so we decided to look into a metabolism booster called Phenolox. We examined the ingredients, side effects, clinical research, as well as customer-service quality. We also scoured the web for user experiences. Then, we summarized and condensed it all to give you the info you need.

What is Phenolox?

First, Phenolox ingredients are green tea extract, Advantra Z, l-carnitine, l-phenylalanine, cayenne pepper extract, coleus forskohlii, chromium picolinate, and di-potassium phosphate. [1] [2]When taken as directed, Phenolox supposedly boosts metabolism, suppresses appetite, and burns fat. One pro is portability of the pills.

Phenolox is made by a company called Metabolic Nutrition, which was supposedly started in 1988. It’s available on the official website for $52.99. Phenolox contains some natural ingredients and it’s certainly simple to use, but read on…

Cost – “Breaking the Bank?”

The first concern we had with Phenolox ingredients was the high cost. “The big ingredient in this one is green tea. That can be purchased for less than $5 at your local pharmacy,” says our Research Editor. [3]

“Spending $53 isn’t that bad, but when it only lasts less than two weeks, it gets expensive,” said a customer.

“It’s just too expensive to continue to buy on a regular basis,” reported another.

Phenolox Side Effects – “Another Concern”

We have some concerns about Phenolox side effects. “There have been reports of fainting in healthy people after taking bitter orange supplements alone or combined with caffeine,” the NIH says. [4]

“I like this product, but within hours it gives me a terrible headache,” said a consumer. [5]

“I’ve been experiencing a itching/hot or burning episode around my lips, both arms, neck and head,” stated another.

“Taking for a few days , but I feel angry,” reported a user.

Over years of research, we’ve found that it takes a small thing, like negative side effects, to ruin any chance of long-term effects. If Phenolox causes adverse reactions in customers, we have concerns.

The Science – “Any Real Proof?”

Scientific research is incredibly important when you make a supplement decision. There is research into some Phenolox ingredients, but the findings don’t relate to this formula. At DietSpotlight, solid science is imperative. If there’s none, we start to raise the red flag.

The Bottom Line – Does Phenolox Work?

Are we racing out for this one? Well, we like that we found some positive customer comments and that it contains a few natural ingredients, but the lack of research supporting the weight-loss claims has us a bit concerned about this one. Also, with customers talking about negative side effects and a high price tag, this leaves us even more skeptical.

If you need a supplement to boost weight loss, we suggest going for something that offers real results for an affordable price. Clinical research is a pretty big deal too.

Among the best products we’ve seen this year is one called Dietspotlight Burn. It includes four ingredients, clinically tested and shown to help boost metabolism, curb appetite and fat loss. We’re also thrilled to find some amazing customer reviews.

A Special Trial Offer makes Dietspotlight Burn all the more appealing to try. This tells us the makers are confident in their supplement.

Does Phenolox work?

We can say that Phenolox contains green tea extract. The ingredient has clinical backing showing it can help with weight-loss. But, we are most interested in the Advantra Z, because customer reviews and research report some negative side effects. If you drink caffeine of any kind, the risk of adverse reactions increases.

You may want to switch out Phenolox for a supplement that’s made with clinically tested ingredients and supported by strong customer reviews, like Dietspotlight Burn.

How much does Phenol cost?

Phenolox can sell for up to $53.00.

How should I take Phenolox?

Based on the label, you should not take more than two capsules a day. Avoid taking it in the evening. If one capsule lasts more than 15 hours, it is suggested to take one capsule every other day.

Can I take Phenolox if I have a health condition?

You should ask your physician if you have other underlying health problems, are pregnant, nursing, under the age of 18, or taking prescriptions.

Is there any caffeine in Phenolox?

There is some green tea in Phenol and that supplies caffeine.

Should I diet or exercise on Phenolox?

Diet and exercise are a great way to promote weight-loss, but neither is required.

Does Phenolox come with a guarantee?

Phenolox comes with a 30-day money back guarantee if you are not 100% satisfied with your purchase.

This is a mineral that’s commonly found in the human body. It’s important for digesting foods. Also, it’s found in foods such as some meats, potatoes, cheeses and cereals. Chromium is used in supplements as well. [1]

What is it Supposed to Do?

First off, chromium is often said to help manage blood glucose levels. It also assists by converting proteins, fats and carbohydrates into energy. Some common forms of chromium used in weight-loss pills include chromium picolinate and ChromeMate. There is some evidence that suggests this mineral helps with weight management.

Clinical Research

According to the American Diabetes Association, one study showed some results. It said, “Some people taking chromium picolinate with sulfonylurea agents significantly improved insulin sensitivity and glucose control. Further, chromium picolinate supplementation attenuated body weight gain and visceral fat accumulation compared with a placebo group.”

Clinical testing is an important part of the equation when it comes to choosing a diet supplement. You may want to take a look at a product like Dietspotlight Burn. It contains some ingredients that have been researched.

Vitamin B12

Also known as cyanocobalamin, this is a water-soluble vitamin that’s found in foods like dairy, shellfish, eggs and some cereals. It’s important for the metabolism of proteins. Vitamin b12 also helps create red blood cells. [2]

What is it Supposed to Do?

Many dietary supplements and multivitamins contain vitamin b12. This ingredient is often claimed to boost energy levels and support weight-loss. Some studies have shown that this vitamin can help with conditions like pernicious anemia.

Clinical Research

In regards to weight-loss, there is really no evidence to support vitamin b12. The Mayo Clinic conducted one study with injectables. Their conclusion was, “There’s no solid evidence that vitamin B-12 injections aid weight loss.”

Vitamin B6

Sometimes referred to as pyridoxine, vitamin b6 is commonly found in cereals, liver, eggs and some vegetables. It helps protect the immune system. Also, it helps convert food into energy.

What is it Supposed to Do?

Often vitamin b6 is used in supplements to help elevate mood and boost metabolism. After all, it is needed for proper metabolism health.

Clinical Research

According to Brad Chase of Progressive Health, “There is no clinical evidence to suggest that vitamin B6 can be used to achieve weight loss.” Also, Donald Hensrud, M.D., of the Mayo Clinic, says, “Little to no evidence exists that any kind of vitamin supplement will help you lose weight.”

Is There Anything Out There That We Think TRULY Works?

We have our eye on a supplement that fits the bill. Dietspotlight Burn, which is formulated with ingredients that HAVE been clinically tested, may be a good option. All customers can take advantage of a Special Trial Offer, currently available. Click here to give it a try.

Some of the major active ingredients in Phenolox include Advantra Z and Green Tea Extract. Green Tea Extract has fast become one of the most common ingredients in weight loss products on the market today. Advantra Z is made from Citrus Aurantium, which many manufacturers of weight loss products now use as an alternative to the now banned, once-popular ingredient ephedrine. The other ingredients in Phenolox are ingredients that can commonly be found in other similar weight loss products on the market today.

There are a number of warnings that come with this product, so if you have any existing health problems or are taking any kind of prescription medication you should carefully read the contraindications. Some experts also urge caution due to the use of Citrus Aurantium, which is also known as Synephrine and Bitter Orange Extract, whien included in any weight loss products as they believe that it may increase the risk of a stroke or heart attack. Phenolox can be ordered directly from the official website at a price of $52.00 for a bottle. There is also a money back guarantee if for any reason you are not satisfied with the product.

    Have been using this product for over a year…went from 145 lbs. to 125 lbs. I don’t diet but I love to run and gym it. Never had a side effect, but someone mentioned loss of hair, which has happened since I started this. Not as regular, but happens when I leave this supplement alone for 3 months, than come back too. I do this skip because it helps me to kick start my metabolism & more weight loss becomes immediate. Recommended this is several peeps & they all love it.

    Wonderful exapanltion of facts available here.

  •  People at Natural body recommended
    Lisa (Verified User)

    Just finished my first bottle and now buying my second. People at Natural body recommended taking a thyroid protector to take with it so well see how it goes. I lost weight but it’s only because it took my appetite away completely. I could literally go the whole day without eating so I lost a few pounds. Bad side is once i stopped taking it for 3 days it didn’t work until the next few consecutive days of taking it. Definitely gave me the good clean energy feeling. I am recommending this product to my friends who are sensitive to caffeine.

  • using phenolox for long period of time
    Jennifer pratt

    Any reports of hair loss while using phenolox for long period of time?

    • Your Name

      My co worker is half way through her bottle and said she thinks it is making her lose lots of hair. I haven’t experienced this and I finished a whole bottle.

  • This product contained Yohimbe

    On the front of the bottle said: no Yohimbe in it – but on this page Yohimbe is listed as an active ingredient? This product contained Yohimbe or not?

  •  It works but with side effects.
    Sfole211 (Verified User)

    I have been taking for 40 days. Works great. Lost over 20 pds. Just started new bottle and am now having a very bad red rash on face and extremities about 10 minutes after ingestion. Very hot! Takes 45 minutes to clear. A bit scary and left me with a headache. Not sure what the new bottle has that the old one did not. Has happened to a few of my friends that have taken it too. A bit afraid to take it again.

    • Harris

      Ive just had the same reaction today…come to find out that there is a bad batch and something to do with the Niacin. the batch # is 2541 10 16. My other bottle did not have the same issues and it is a differnt batch #. I am going to call Metabolic Nutrition tomorrow and see what they can do as far as a return. hope this helps.

      • Karen

        I have been wondering why the 2nd bottle I started taking did the same thing. Same batch # too. I hope the company does something about this, not fun.

      • Joyce benoit

        This very interesting. I’ve been experiencing a itching//hot or burning episode around my lips, both arms, neck and head only in the morning and not every day. It last 20-30 mins and leaves me slightly washed out. I just emailed my doctors nurse. I’ve been searching all evening for drug interactions then stumbled on this thread. The batch of Phenolox is 2540 10 16. The previous labels were red and this one is orange. I’ve wondered about this since I rec’d it.

        • Your Name

          I had a similar reaction. I think its the Niacin flush. I informed the company and received a new bottle that did not have that effect.

    • Lasandra

      Just started taking it , how many capsules did you take a day to lose 20 pounds in 40 days?

  • I like this product, but within hours it gives me a terrible head ache, please let me know why this is happening?
