What is Nutrex?

Nutrex is a supplement company that sells products for working out – based on the images and products available on the official website. The average person may be a little overwhelmed by muscle-laden men selling a fat burner – or men carrying 100+ pound dumbells. This is clearly not a company for the average Joe.

Does Nutrex Work?

  • Nutrition and Metabolism — “It has been suggested that protein hydrolysates providing mainly di- and tripeptides are superior to intact (whole) proteins and free amino acids in terms of skeletal muscle protein anabolism.”
  • National Institutes of Health — “Vitamin B6 in coenzyme forms performs a wide variety of functions in the body and is extremely versatile, with involvement in more than 100 enzyme reactions, mostly concerned with protein metabolism.”
  • National Institutes of Health — “Zinc is involved in numerous aspects of cellular metabolism.”

Company and Better Business Bureau

According to the Better Business Bureau (BBB) page, there have been no reviews or complaints filed against the company in more than eight years since the BBB file was opened.

Details on Ingredients

Let’s take a look at how these ingredients work to improve weight loss or boost testosterone.

Caffeine, D-Caffeine Malate: Caffeine works as a stimulant (energy booster) and improves focus or attention, as per research in Brain and Cognition.

According to a study published in the International Journal of Food Science and Nutrition, there’s also research that shows caffeine can reduce calorie intake three to four hours before eating.

Whey Protein Concentrate, Hydrolyzed Whey Protein, Whey Protein Isolate: Protein is a secret weapon in weight loss. Whey protein supplements have been shown to help reduce appetite and calorie intake, claims research in Obesity (Silver Spring).

Theobromine: Theobromine, when paired with caffeine, may improve mood and alertness, according to Frontiers in Pharmacology. There’s also some research, only in the rat testing stages at this time, that shows theobromine may help improve working memory.

Citrus Aurantium: Citrus aurantium has stimulant properties similar to caffeine. According to the International Journal of Medicine, research shows supplementation for six to 12 weeks may increase weight loss. It’s important to note that citrus aurantium, as a synephrine source, could cause side effects similar to ephedra. However, a 2018 study in the journal Oxidative Medicine and Cellular Longevity claims supplementation has “no unwanted effects in humans at therapeutic doses.”

Yohimbine: Yohimbine shows promise in promoting fat loss, according to a study in Research in Sports Medicine, but the study was completed in 2006, and more current studies are lacking.

Tribulus Terrestris: Some of the most recent research into tribulus terrestris shows it may not have any effect on testosterone levels, but it may improve specific sperm parameters in men with infertility, according to research in the Journal of Ethnopharmacology.

Eurycoma Longifolia: Also referred to as tongkat ali, eurycoma longifolia has long been used in natural testosterone boosters, but 2019 research, as published in the International Journal of Preventive Medicine, shows it does not affect serum testosterone levels.

Weight Loss

Nutrex Research and Weight Loss

Caffeine and yohimbine both have clinical support for use as a weight-loss supplement. Caffeine is especially useful as it can reduce appetite, increase focus, increase energy, and reduce fatigue.

  • Good prices.
  • Variety of supplements, including a stim-free fat burner.
  • You can purchase online and in major stores like Walmart.
  • There is the contact information for the customer service department.

What Users Are Saying

What Users Are Saying

“King of fat burner – I use lipo 6 b4 it help alot I lost 70lbs in 2 months so I decided to take this one and it kill my hunger for real mad energy but I’m lost on the color of it if the pills post to be green or black I have the green pills idk cuz u see fake ones online.”

“Worst stomach ache ever. And you’ll get an anxiety attack for sure. I took so many products before and never experienced this 🙁 I tried to return since I only took it for one day, but it doesn’t give you the option to do it. So disappointed.”

“This is the first pre workout I’ve ever tried and I have to say, I’m very impressed. The scoop is bigger than your usual pre workout, and since I dry scooped, I had to do half the scoop twice to make sure I didn’t over do it, but 10 minutes later I could feel the tingling in the face and hands which I actually liked. The flavor wasn’t too bad when dry scooped but it probably tastes better when actually mixed with water as a drink. It was a very fine powder which i liked, and I noticed it definitely gave me a lot more energy than I usually have at the gym, I was able to withstand heavier weights. I’d say this is definitely worth your money, the only reason I took a star away is because the container is big but it’s only filled half way so I would’ve liked it to be filled more. But overall, very effective, I could tell with just one use that it does help with weightlifting and does have long lasting energy!”

Bottom Line

Bottom Line on Nutrex Research

We like that Nutrex comes with some reasonable prices, and there are some good options in weight-loss products, but there’s nothing new here. The company’s biggest seller, we suspect, is the Lipo-6 line of weight-loss products. Within that line are some decent products that may deserve a closer look.
