The Protein Works Red-Cell Overview

What You Need To Know About The Protein Works Red-Cell

The Protein Works Red-Cell is a diet supplement that is said to work as both a fat-burner and an energy-boosting pre-workout. The manufacturers enthusiastically advertise this product’s supposedly ground-breaking capsule design, which consists of an outer shell made up of Conjugated Linoleic Acid (CLA) and an inner capsule that contains the remaining ingredients. This “dual-release” technology supposedly makes it so that the ingredients “can be transported into the body at the same time”.

What Are The Side Effects Of The Protein Works Red-Cell?

This product contains a mixture of citrus aurantium and caffeine, which is often associated with side effects. Potential side effects resulting from mixing these ingredients include heart palpitations, high blood pressure, sleeplessness, jitters, and more. Customers have also complained of sweating and “feeling hot”, which is likely the result of either the above combination or of the use of capsicum.

How Much Does The Protein Works Red-Cell Cost?

On the official manufacturer’s website, a one-month supply (90-capsule) pack of Red-Cell costs £32.99 (plus £2.99 in delivery charges). The same pack can be found for around £25 on Amazon and

Our Verdict On The Protein Works Red-Cell

Although The Protein Works tries hard to get customers excited about its capsule design, most should easily be able to tell that their spiel is all bluster and no substance.

The ingredients list used in this product is far from impressive, utilising lacklustre ingredients like CLA, capsicum, and phenylalanine. For context, these ingredients could help to burn fat, but at a sluggish rate (you may be able to burn off the biscuit you had this morning and nothing more). To make it worse, any talk of this product acting as a pre-workout is an outright fib, as the quantity of caffeine included in this product is far too low to be effective.

Despite this, we have still heard complaints of side effects from former unhappy customers. Those dissatisfied with their purchase are out of luck, as the manufacturer does not offer anything resembling a money-back guarantee. Instead, they simply offer store credit or an exchange; fine if you’re a fan of The Protein Works, but useless for most of us.

Overall, we find this product to be a weak and lifeless fat burner in a market packed with better alternatives.

We do not recommend The Protein Works Red-Cell to our readers.

The Protein Works Red-Cell Key Features

The Protein Works Red-Cell is a supplement that is designed to come with a “dual release technology”. The manufacturers claim that the unusual design of the capsule and the unique mixture of ingredients means that it can work well as both a pre-workout and weight loss aid. Like many other weight loss or pre-workout products, Red-Cell contains stimulant ingredients like caffeine.

The Protein Works Red-Cell Facts

  • Manufactured by The Protein Works
  • Contains 90 capsules per pack
  • Dual-action supplement that functions as a pre-workout and weight loss aid

This product is manufactured by The Protein Works, a sports nutrition brand based in the UK. Founded in 2012, the company has since expanded greatly, and now sells products throughout Europe and internationally. Since the 2014/2014 season, the company has also been the official partner of the Premier League soccer club, Everton FC, and received the “New Business of the Year” award at the UK’s National Business Awards two years after the company’s launch. The company can be contacted via the details supplied on its official website.

How to Take The Protein Works Red-Cell

The directions for use are as follows:

  • We recommend consuming three capsules 30 minutes before your workout. Alternatively, consume one capsule in the morning, one capsule with your lunch and one capsule late afternoon. Do not exceed the stated dose.

The Protein Works Red-Cell Concerns:

  • Very few customer reviews, with the few available often negative
  • No money-back guarantee
  • Official sales page makes a number of false and hyperbolic claims

What Does The Protein Works Red-Cell Claim To Do?

On the official sales page for Red-Cell, the manufacturers claim that this product can function as both a pre-workout and as a weight loss aid. Its “dual release technology” is also much-hyped, with the advertisers claiming that this “breakthrough” technology allows potent weight loss and energy-boosting ingredients to be combined and released together “for the first time”.

Customers choosing to purchase Red-Cell are told to expect fat loss, reduced hunger cravings, and a strong energy boost. Those using the product can also supposedly train harder over longer periods of time, helping to break barriers and PBs.

Does The Protein Works Red-Cell Work?

Although the manufacturers are keen to emphasise that this product offers a large dose of conjugated linoleic acid (via its “breakthrough” delivery system”), this and many other ingredients are actually highly unimpressive in reality. Regardless of the capsule design, ingredients like CLA, cayenne pepper, phenylalanine, and green coffee bean have been repeatedly found to be weak and inconsistent weight loss aids.

The only mechanism that may work to provide a fat-burning, appetite-suppressing, and energy-boosting effect, is the simple combination of caffeine and citrus aurantium. The dosage of caffeine used in this product is actually fairly low – good news for avoiding side effects, but bad news when the caffeine is one of the only ingredients in this product that actually works.

Overall? We would expect this product to act as a relatively weak fat burner. With a tiny energy boost and no muscle-building compounds, it basically doesn’t function as a pre-workout.

What Are The Ingredients of The Protein Works Red-Cell?

The ingredients found in The Protein Works Red-Cell are listed below. The quantities listed are correct for 1 soft gel capsule.

  • Cayenne Extract 8:1 36.5mg: Capsaicin, which is found in Cayenne pepper, is thought by some to play a role in weight loss. Some studies suggest it could suppress the appetite mildly, whilst others suggest that the heat causes a thermogenic reaction in the body, burning more calories for a period of time. However, there are also studies that show cayenne has little or no effect upon weight loss attempts. Source
  • L-Phenylalanine 8mg: This ingredient is an essential amino acid that is naturally found in meat, eggs, and other protein sources. It is not often associated with weight loss, and some early studies were undertaken to examine its effects found it to have no impact on weight loss or hunger levels. Source
  • Green Coffee Extract 20:1 3.5mg: Whilst it was thought that Green Coffee Bean was a significant aid to weight loss due to its chlorogenic acid content, the relevant research has been discredited as it was fraudulent. Currently, there is no evidence that it aids with weight loss more than any other source of caffeine. Source
  • Bioperine 1.5mg: This patented Black pepper extract is used for increasing the bioavailability of nutritional compounds. In other words, it increases the amounts of nutrients that are absorbed into the body in the digestive tract. It may also increase the absorption of various drugs, which may lead to potential side effects. Source
  • Vitamin B6 0.2mg (15% EU RDA): Vitamin B6 has several important functions in the body, including ‘allowing the body to use and store energy from protein and carbohydrates in food’. Whilst taking excess amounts of vitamin B6 will not infinitely improve this ability, a deficiency could make it more difficult to lose weight. Source
  • Chromium Picolinate 21µg (15% EU RDA): Chromium is used primarily to lower fasting blood sugar levels and insulin levels in people who have type 2 diabetes. In terms of its potential effect upon weight loss, it is possible that taking chromium picolinate by mouth for 2 to 3 months might produce a small weight loss of about 1.1 kg. This is obviously an incredibly small amount of weight loss, but studies are still inconclusive. It also helps to reduce insulin resistance. Source
  • CLA 450mg: Conjugated Linoleic Acid may help to reduce body fat, but may not cause changes to body weight. Human studies of CLA have produced contradictory results, and it is described as not only a relatively poor fat burner, but also an unreliable one. Source
  • Citrus Aurantium 100mg: Also known as bitter orange peel, Citrus Aurantium has been proven to raise the metabolism and aid weight loss. It contains numerous stimulant compounds, including synephrine. A review of numerous studies concluded that the use of synephrine resulted in an increase to the participants resting metabolic rate and energy expenditure, and moderate weight loss was seen in studies lasting over 6 weeks. However, there are some concerns about its safety being under-researched and the numerous side effects that have been associated with it. Source
  • Caffeine 70mg: Numerous studies have shown that caffeine boosts energy levels and alertness, as well as mildly boosting the metabolism, causing a small increase in the number of calories used by the body. The effects shown in studies are small, and some studies are inconclusive. Source

Does The Protein Works Red-Cell Have Any Side Effects?

Like many other stimulant-based fat-burners, this product can cause a few side effects.

This product’s main fat-burning action is the result of combining citrus aurantium and caffeine. Unfortunately, this effective combo can also cause a range of side effects, including headaches, increased heart rate, increased blood pressure, heart palpitations, increased urination, dehydration, jitteriness, dizziness, and insomnia. Citrus aurantium is often singled out as particularly risky, sometimes causing increased blood pressure, heart palpitations, fainting, and even heart attacks and strokes in healthy patients. The Mayo Clinic has recommended avoiding the use of Citrus Aurantium because, in their opinion, the risk of using the product is not worth the pay-off of some weight loss that could be achieved using other means.

Capsiacin and capsicum can sometimes cause mild side effects like sweating, flushing, a runny nose, and stomach irritation. CLA can cause stomach upset, diarrhoea, nausea, and fatigue. It can also increase triglyceride levels in some cases, sometimes sharply.

Bioperine increases the bioavailability of other compounds, including caffeine and some medications; this could increase the chances of side effects from the other ingredients found in the product, or from caffeine consumed from other sources (tea, coffee, etc). Consumers who are taking medication are also more at risk of accidentally overdosing because of the higher absorption rate associated with Bioperine, and so should consult with their doctor before taking this product.

Not suitable for pregnant or breastfeeding women. Not suitable for anyone under the age of 18. If you are taking any medications or are unsure about the suitability of this supplement for you, consult your doctor before purchase.

Are There Any Customer Reviews For The Protein Works Red-Cell?

We were able to find almost no customer reviews discussing Red-Cell online (as always, we do not count reviews posted to the official sales website, as these are often unfairly edited or outright-invented by manufacturers). The two comments we could find on Amazon are listed below. Although one of the two reviews complained of side effects, the other found Red-Cell to be effective.

Seems that it works! Easy to swallow too. Good work!

I Go to the gym, eat clean and these added no positive benefits. Didn’t work for me unfortunately just made me hot.

Does The Protein Works Red-Cell Offer a Money-Back Guarantee?

The Protein Works do not claim to have a money-back guarantee, as dissatisfied customers are not offered the right to return unwanted purchases for a full refund.

However, they do offer an alternative “Lifetime Guarantee”. Customers looking to return a purchase may contact the company any time after purchasing to return their products and receive an equivalent product of the same price or store credit (although customers must pay for the back-and-forth shipping). The company will weigh all returns and will only credit the customer for the percentage of the product that remains unused.
