Product Overview

CRN-5 Review Best Creatine PowderWhat is Ultimate CRN-5?

Ultimate CRN-5 is a creatine supplement by Crazy Nutrition that promises to help you get the best out of your workouts by increasing your energy an intensity. As a result, it helps you to build muscle much faster than you would on a regular diet and exercise. Additionally, it also helps enhance your recovery times. 

This cutting-edge breakthrough formula packs five powerful creatine and electrolytes that boost your performance in the gym.

Furthermore, all the ingredients in the Ultimate CRN-5 are natural. It has no synthetic ingredients, chemicals, or preservatives. This is an important point, as all natural speaks for itself, especially in the sometimes shady underworld of workout supplements.

Also, it’s free from fillers, additives, and soy. So it is safe and has no side effects.

Why is Ultimate CRN-5 Becoming So Popular?

The primary reason why Ultimate CRN-5 is becoming popular is its creatine formulation. It’s not every day that you get five types of creatine in one supplement. It makes a huge difference, and this is novel in the marketplace.

Creatine is the most widely researched muscle-building supplement. Studies have shown that regular use helps enhance strength and power, and build lean muscle. Moreover, it is also known to reduce fatigue and improve muscle recovery times. (1)

Now, imagine having five different types of creatines in one supplement. What they can do and how much power you can have to do those heavy lifts. That’s what Ultimate CRN-5 offers, and it’s the main reason for CRN-5’s meteoric rise in the fitness industry.

Most athletes use creatine supplements to get the best out of their training sessions. But regular formulas only contain one type and, at most, two types of creatine. That’s the reason why many are opting for CRN-5.

Additionally, Ultimate CRN-5 has premium electrolytes. All work together to help you get better performance and faster recovery.

Creatine PowderUltimate CRN-5 contains nine ingredients that make it unique and powerful. Of the eight, five are creatine, and four are electrolytes. This is a powerhouse combination by any standard.

They include: (Lemon & Lime)

  • 3,750 mg Creatine Monohydrate per serving
  • 500 mg Creatine Ethyl-Ester per serving
  • 500 mg Creatine Hydrochloride
  • 500 mg Tri-Creatine Malate
  • 250 mg Creatine Citrate Pyruvate
  • 56 mg Aquamin® Magnesium
  • 300 mg Aquamin® AG
  • 1.25 g Sodium
  • 128 mg Potassium

Creatine Monohydrate

Monohydrate is the type of creatine you will find in most creatine supplements. It’s also by far the most widely researched creatine among the rest.

A 5-gram daily creatine monohydrate intake promotes fat-free muscle mass and strength in your body. Generally, it aids in phosphocreatine secretion, increasing muscle fuel, recovery, and repair. Additionally, some studies suggest that it can protect your body against neurological diseases such as Parkinson’s and Alzheimer’s disease. (2)

Creatine Ethyl-Ester

Ethyl-Ester is the creatine responsible for the instant power flowing through your muscles. It improves the absorption of creatine in the body, increasing its effectiveness. It also enhances the electrical impulse, allowing you to focus even during opposition training. Plus, it can help improve body composition for non-athletes and underweight people.

Creatine Hydrochloride

Hydrochloride is the second most widely used form of creatine. Due to its high solubility, it helps improve your digestion and reduce stomach upsets.

Furthermore, its solubility gives it a higher advantage in water retention. This quality makes it much more effective for recreational weightlifters.

Tri-Creatine Malate

Tri-Creatine Malate supports ATP production in your muscles, increasing endurance, energy, and recovery. It does all that without causing stomach bloating or gas. Like the hydrochloride, this too is highly soluble, making it an ideal compound necessary for water retention. (3)

Creatine Citrate Pyruvate

Creatine Citrate Pyruvate is responsible for fighting fatigue. It allows you to exercise way more beyond your usual limits without breaks. As a result, you get to build lean muscles and excess fat.

Aquamin® Magnesium

Aquamin® Magnesium is an electrolyte that promotes protein synthesis, supporting healthy muscle formation. That reduces fatigue and promotes speedy recovery.

Aquamin® AG

It contains calcium and silver minerals. Silver helps reduce inflammation & tissue infections and improves wound healing. Calcium increases bone strength, reducing cramping caused by long workout sessions.


Sodium maintains the proper functions of cells, nerves, and muscles. This three-fold benefit is essential for muscle growth. It also regulates nerve impulses and muscle contraction during workouts.

Additionally, sodium improves your cardiovascular health and balances your electrolytes. It may also significantly reduce the risk of kidney stones and high blood pressure. (4)


Potassium is a mineral rich in electrolytes that maintain hydration and support muscle strength. Other benefits include:

  • Increased energy and endurance
  • Reduced muscle soreness and tiredness
  • Enhanced muscle recovery and athletic performance

Flavors / Taste for Ultimate CRN-5

CRN-5 Reviews HonestUltimate CRN-5 comes in two delicious flavors. They include:

  • Orange & Mango
  • Lemon & Lime

There are not a wide variety of flavors in any creatine powder on the market. And Crazy Nutrition’s CRN-5 has solid flavoring compared to other brands we have tested.

And their two current flavors, Orange & Mango and Lemon & Lime, are surprisingly tasty. They have a sweet taste, but not a bitter taste like many other creatine powders on the market.

Now that being said, everything is relative! After doing a lot of research about the better taste of Ultimate CRN-5, the first time I tried the Lemon & Lime I was not thinking “Wow, this is absolutely delicious! I think I’ll have some for dinner too, it’s just so tasty!” But in terms of other creatines that I’ve tried, it’s definitely among the best and I thought it was pretty good.

Highlighted Best Features

  • 30 servings per container
  • 5 unique creatines
  • 3 premium electrolytes
  • Caffeine-free
  • Vegan-friendly
  • No banned substances
  • Delicious orange & mango and lemon & lime flavors

Another one called Joe C. wrote, “First time user. It’s still too early. However, I have noticed I can go heavier on certain lifting exercises than I wasn’t doing before taking CRN-5. The taste isn’t great but I’m not taking it to enjoy a cold beverage. So far it’s helping in the areas it claims to help in, I’ll keep buying it for sure.”
