RSP Nutrition Whey Protein Powder Review

This RSP Nutrition Whey Protein Powder Review will focus on a protein shake supplement made by a manufacturer who has been in business since 2009.

RSP Nutrition has a bunch of different products and focuses mainly on increasing the performance of people who consume their supplements.

We’ll take a look at their Whey Protein shake and see exactly what it contains, what it can help with and whether it’s worth your hard-earned cash.

Apart from this RSP Whey review, this supplement is also featured in our Top 10 Lists of the Best Protein Supplements for Men and Women, which you can find at Top 10 Best Protein Powder Supplements for Men and Best Protein Powder Supplements for Women.

Supplement Overview of RSP Whey Protein

RSP whey protein is a blend which contains Whey Protein Concentrate, Whey Protein Hydrolysate, Whey Protein Isolate and Milk Protein Isolate.

This makes the protein powder supplement very versatile and all-purpose.

Since it has slow-digesting, medium-digesting and fast-digesting sources of the vital macronutrient – it can be taken at absolutely any time.

It’s great just before exercise or even during a training session – as well as when just waking up or right before going to bed.

All of this makes RSP whey great for weight loss, as it will keep you satiated for much longer, while also providing all of the benefits of fast-absorbing proteins.

Plus, depending on your training goals, whether you want to lose weight and get lean body mass or gain weight, you may want to combine whey with the best mass gainers, the best BCAA supplements, best testosterone boosters, and also the best creatine for men powders.

Women can benefit greatly from adding whey to other supplements like the best fat burners for women, as well as the best pre-workout for women powders.

Now let’s move on to the main part of this RSP whey protein review – the ingredient analysis!

Ingredient List Analysis

Whey Protein by RSP Nutrition Full Ingredient List

As previously stated, the biggest thing of note is the inclusion of four different types of protein – Concentrate, two Isolates, and Hydrolysate.

Concentrates have low levels of fat and cholesterol but tend to contain high levels of carbs as lactose. They’re also around 29-89% of protein by weight and tend to retain most nutrients naturally found in whey.

Isolates are mostly fat and lactose-free and provide around 90%+ of protein by weight. This form is perfect for those who are lactose-intolerant or want fast-acting protein.

Hydrolysates are a predigested and partially hydrolyzed form made for the purpose of easier absorption and metabolizing. They’re best for those who have digestion problems or various allergies but come with caveats of being the most expensive and spiking your insulin levels by around 28-43% more than standard forms do.

Here are more things to note:

The Cholesterol content is quite high, at 20% of daily value per serving, which isn’t that great.

The supplement also contains a slew of unnecessary and artificial ingredients, such as Artificial flavorings, Polydextrose, which is a synthetic polymer of glucose, and Sucralose.

It’s a shame that the manufacturer included all these additives and sugars, given the final result – a bland and unpleasant taste.

So people who want their protein powder product to taste great should avoid this supplement and choose a better-tasting one instead!

Finally, the product also contains helpful enzymes: Papain and a Protease. They help aid digestion and provide a couple of other benefits like faster absorption and breaking down of proteins.

All in all, the ingredients seem decent, but some are unnecessary and unhelpful.

Product Features: The PROs and CONs of Whey Protein by RSP

Whey Protein by RSP Nutrition

So now that we’ve discussed the ingredient content, let’s see what all the other facts of this protein powder supplement are:


  • Low Calories
  • Ultra-Filtered for Rapid Absorption and Bioavailability
  • Premium Quality Ingredients
  • Fast, Medium and Slow Digesting Proteins
  • Very Versatile

RSP Nutrition employs a unique cold ultrafiltration manufacturing process for this supplement, which ensures great solubility, bioavailability, and pureness without denaturing or compromising the quality of the protein.

That, along with the versatility of the product, is undoubtedly the main highlight of this sports nutrition supplement.


  • High Cholesterol
  • Some Unnecessary Ingredients
  • Exposed to Many Allergens During Manufacturing (milk, eggs, soy, wheat, shellfish, fish oil, tree nuts and peanuts)
  • Sub-Par Taste

As previously mentioned, it includes quite a few unnecessary ingredients, which are there to improve the taste but fail miserably.

A lot of users who have tried RSP Nutrition Whey have reported that they did not like the taste at all – that it was simply sub-par and the supplement was hard to drink.

Additionally, the product is made in a facility which processes a lot of other foods, which makes it potentially harmful for those who suffer from and have various allergies.

Our Evaluation of This Protein Supplement

We think that the whey protein made by RSP Nutrition is pretty decent.

While not ideal and containing several unnecessary ingredients and additives, it certainly does the job and provides a very versatile form of the main macronutrient for building muscles.

However, we do think that there are much better alternatives on the market, for example, Transparent Labs Grass-Fed Whey which you can read about at Transparent Labs Grass Fed Whey Protein Review and also Catalyst Grass-Fed Whey by Strength, which you can find at Catalyst Grass Fed Whey Protein Review.

As we’re always saying, your health is important to us. That is why we always suggest the healthiest option instead, and when it comes to various whey products – the healthiest alternative is always whey from grass-fed bovine sources.


To finish this off, don’t forget that we have other top lists with the healthiest products from reliable manufacturers:


RSP whey protein powder has its benefits and is a pretty good supplement, especially due to its unique cold ultrafiltration manufacturing process.

Unfortunately, there are just too many better alternatives on the market, so it sits smack dab in the middle – being neither bad nor great.

Since the price is affordable, many people will find that it suits their needs perfectly, but if you are very health-conscious and want a much healthier alternative – there are much better products to choose from.

So what do you personally think about this type of whey supplement which includes a blend of various proteins? Do you personally think that including Concentrates, Isolates, and Hydrolysates in one supplement is a bad choice or not?

If you’ve had any experience with various protein blends and would like to share it – or even if you prefer having just one type of whey protein – let us know in the comments below, because we’d love to discuss this further!
