NutraBio Extreme Mass Gainer Review: The Good, The Bad and The Ugly

Best for: Clean Bulking Calorie Counters

Overall rating

4.6 out of 5.0 stars

This product does not hide behind “proprietary blend” claims that trick you into drinking sugars and fillers. It discloses all of its dose-effective ingredients on its label so you know exactly what you are consuming.

It delivers an optimal dose of proteins, carbs, and fats; no more than your body can digest in one period. Plus, it has just the right amount of calories per serving to help you clean-bulk.

Its whey and casein blend ensures you have both fast and slow-digesting proteins for anabolic and anti-catabolic effects. With its unique carbohydrate mix, you will have enough energy supply for pre, peri, and post-workout all in one serving! 

I’ll cover the most important factors in-depth, but to start, here’s NutraBio Extreme Mass at a glance:

In this review, we will be looking at NutraBio’s Extreme Mass Gainer and learn whether it stands out from the rest of the mass gainers available on the fitness supplement market.

We will be looking at the pros and cons of this product by examining its formulation. 

Specifically, we will go in-depth on the following:

  • Macronutrient ratio
  • Protein blend
  • Carbohydrate quality
  • Nutrient-timing
  • Calories delivered
  • Overall value

In my opinion, this is probably one of the best mass gainers out there. 

And, I love the company’s “no BS” approach. If you would like to know why it got a very high 4.6/5 rating, keep reading until the end…

Before we proceed to the detailed review, let’s first get the low-down on NutraBio Extreme Mass.

This mass gainer delivers a total of 53 grams of fast and slow absorbing protein that gives you a steady supply of amino acids for up to 3 hours. 

70% of it comes from whey concentrate and 30% comes from micellar casein. This awesome combo creates an anabolic and anti-catabolic environment that lets you build the most muscle mass.

It fuels your body with 104 grams of complex carbohydrates per serving

It only has 3 grams of sugars, the rest are high-polymerization carbs. Although they are absorbed quickly, they do not spike your blood glucose levels. So, you have an immediately ready yet sustainably released energy source without the lethargy of a sugar-induced insulin crash.

The label says “do not use it as a sole source of nutrition”, and that is exactly right. The 650 calories it delivers is just enough to supplement a sound meal plan, not replace it.

NutraBio created this mass gainer as a true supplement with precise measurements, time-released nutrients, and the best ingredients – no fillers.

At the beginning of my muscle-building journey years ago, I was really struggling to build muscle, bulk up, and gain weight .

I knew that I had to eat more calories that I burn, creating the calorie surplus that would help me achieve these results.

Though I was gorging myself with food, my body weight didn’t budge. Sometimes I even lost weight!

That’s when I discovered mass gainers. Like you, I wanted to gain muscle as fast as possible. 

But in doing so haphazardly and without any proper guidance, I ended up gaining as much fat as muscle in the beginning. I felt like  all the effort, time, and money I put in were in vain. 

Although I was growing, I was not growing in the direction I wanted.

That’s when I realised that not all mass gainers are created equal. The mass gainer that I took during that time contained 3x the number calories of a normal meal. But without a proper meal and exercise plan that goes with it, gaining fat was inevitable.

In mass-gaining, more is not always better. There is a threshold to your caloric surplus wherein you shift from muscle-gain to fat-gain. That’s why choosing the right mass gainer that fits your goals, diet, and workout plan is crucial.

Who is NutraBio Extreme Mass Gainer best for?

If you are:

  • Meticulous about what you put into your body as well as track your calories
  • An athlete, bodybuilder, or strength athlete that pays close attention to their weight and body composition

…then keep on reading.

However, if you are:

  • Looking for a magic powder that adds muscle overnight
  • Someone who does not have a sound training and nutrition plan
  • Looking for whopping amounts of calories

…then this mass gainer won’t probably suit you. Try Optimum Nutrition’s Serious Mass or MuscleTech Extreme 2000 for a gigantic portion of carbs and up to three times the calories.

The Good, the Bad, and the Ugly on NutraBio Extreme Mass 

Nutritional Profile

The 53 grams of protein per meal is just enough to reach the threshold of how much your body can absorb in one sitting.

The 104 grams of carbs do not push you overboard, especially for skinny lightweight individuals. The complex carbs give you enough energy for a workout with more left afterward to aid recovery.

The carbs and proteins are both time-released. Meaning they give you both a quick source and a sustained source of these essential mass-building nutrients.

The macronutrient ratio of Extreme Mass resembles that of a complete meal, unlike most mass gainers that can easily replace 2-3 meals. 

You should consume most of your calories from real foods, hence, I see no issues with the total calories it has per serving, especially if you are clean bulking.

Verdict

The macronutrient ratio is a winner for me. I am an advocate of clean bulking and gaining muscle mass slowly. This mass gainer delivers exactly what you need regardless of when you take them. It gives you both a quick source and a sustained source of all the essential nutrients.

Protein Content

Extreme Mass’ protein primarily comes from whey concentrate. We know that it is a rich source of fast-digesting proteins. On top of  that, it is high in immunoglobulins that may help fight viruses and bacteria.

The other protein is micellar casein, it not only increases protein synthesis but its sustained release also prevents muscle breakdown during unfed periods,especially when you sleep.

The blend of the two milk proteins makes it perfect to use any time of the day.

Verdict

The proteins in this supplement pack a 1-2 combo of kickstarting muscle protein synthesis and making sure this process continues for as long as possible. You create the best environment for muscle building.

Flavor

It is available in two flavors: chocolate and strawberry. Given that its calories are on the lower end, I would have liked to see a vanilla flavor. This would have given a better flavor base for adding ingredients to bump up the overall calorie count.

Verdict

The flavor of this gainer is better than the average. It can be too sweet and too rich and thick for some since it requires 4 scoops per serving.

Pricing

Comparatively, it’s several bucks more expensive than other 5-7 pound mass gainers. But I think it’s still well worth the price. First, you get a total 16 servings per tub which is on the high side. And, the blend of premier whey and casein proteins does the higher price justice.

Verdict

This is not for people with a tight budget. And, if you are a true hard-gainer that needs a high surplus of calories, I’d suggest you opt for another mass gainer brand. This NutraBio gainer is more tailored towards intermediate lifters who know how to get the most out of its 650 calories.

Check Out My Results From Using “NutraBio Extreme Mass”

This mass gainer helped me get lean gains over the two months I’ve used it. Although my weight on the scale was not moving as much, I felt significant increases in strength, which correlates with increased muscle mass.

Even though I was not gaining pound after pound, in the mirror I can see my physique looked more dense and defined. Take this as an important note when tracking your progress in the gym, often the mirror will tell you more about your physique development than your scale weight.

Here are some Amazon reviews about the product:

(I)t gives you almost all the vitamins and minerals you need throughout the day and plenty of carbs, protein, and healthy fats in one serving and it’s all organic, non-GMO, and vegetarian, etc. It helps those who do not have the time to make or resource’s to Cook 3-4 meals a day. And like it the label on the container says, it’s a supplement, not your main source of food.”

“Taste could be better but love how it doesn’t have a bunch of fillers. Definitely filling”

“I’ve tried many different protein powders and this is the first one I’ve been able to stay consistent with. Tastes great and mixed extremely well with just cold water added. Would definitely recommend trying this product.”

Is NutraBio Extreme Mass right for you?

We’ve covered the pros and cons of NutraBio Extreme Mass. Now, let’s talk about whether or not this is the right mass gainer for you.

As with any supplement, what works well for one person may not work for others. We do have individual needs, resources, and genetics that can influence the overall result of our diet and training.

For the fat conscious clean bulker

Trying to gain lean mass, aka pure muscle, is the best and healthiest route for adding weight to your frame. Although, it is a feat that is not easily doable.

If you aim to have a physique worthy of showing on a bodybuilding stage, you need to be strict with what you eat. The relatively low 650 calories NutraBio Extreme Mass delivers is perfect for a clean bulk to achieve lean gains.

If you want to add as little fat as possible and maximize muscular hypertrophy, this particular gainer is definitely for you.

For the bodyweight watcher

Athletes usually need to stay within a certain weight class during competition. Not only that, they need to build as much muscle as they can to maximize speed, strength, and explosiveness.

For both reasons, the Extreme Mass will be the perfect addition to your daily nutrition regimen. It provides you with enough carbs that slowly release into your bloodstream so you have enough energy to sustain your long training hours. The proteins it contains ensure that you don’t break your muscles down as well as ensure a quicker recovery time.

Alternatives

If you are looking for something with significantly higher calories in one serving, you can opt for Labrada Muscle Mass Gainer or Optimum Nutrition’s Serious Mass which provides 1265 and 1250 calories per serving respectively. These two are best for legit hard-gainers who want to increase overall weight first before focusing on pure muscle building.

Final Thoughts

What is my takeaway from all of this?

The Nutrabio Extreme mass gainer deserves my praises. This is because I find it as a perfect addition to my current needs nutrition-wise, and where I want to be physique-wise.

What about you?

Well, you must first determine what fitness “level” you are in. This requires you to be honest with yourself and your progress, or lack thereof.

Is it for skinny guys? Yes, it is. Is it for already muscular dudes and dudettes? Also, yes. Again, this is no miracle gains-maker. 

Its standout feature is its perfect blend of ingredients, not only with the proteins but also with the carbs. It catalyzes and sustains muscle growth. It incorporates into one product all the desirable mass building features we usually look for separately.

One thing is sure about the NutraBio Extreme Mass, its protein content was deliberately designed for maximizing muscular hypertrophy and minimizing breakdown. 

And, its low-calorie content makes sure you have just more than enough energy from carbs to support your training and that muscle growth.
