How Does Crazy Nutrition Mass Gainer Work?

Crazy Nutrition Mass Gainer supports muscle growth and recovery by delivering a high-calorie, protein-rich formula in every serving. It gives the body the fuel it needs to build muscle, gain strength, and recover faster after workouts.

The formula includes DigeZyme, a digestive enzyme blend that supports nutrient absorption and reduces bloating. A study in Current Drug Metabolism found that digestive enzymes help break down proteins, carbohydrates, and lipids for easier digestion.

It also features AstraGin, a patented compound shown to enhance nutrient absorption. Oat flour provides slow-releasing complex carbohydrates for sustained energy, while the whey and milk protein blend delivers 40 grams of quality protein per serving, supporting energy and recovery during intense training.

Crazy Nutrition Mass Gainer Ingredients – Are they Safe & Effective?

Whey protein blend

Whey protein blend

This whey protein blend comprises of whey protein isolate and whey protein concentrate.

In a double-blind crossover study published in the Nutrients journal, whey protein was found to improve body protein metabolism and performance recovery after resistance training.

Creatine monohydrate

Creatine monohydrate

Creatine monohydrate is an essential ingredient in the best mass gainer proteins. It is claimed to improve muscle performance in high-resistance exercises.

Creatine supplementation is known to have ergogenic effects. In a 4-week study by the Nutrients journal, subjects were supplemented with creatine and asked to take part in complex trainings. Subjects recorded improved maximal muscular strength and reduced muscle damage during training.

Oat flour

Oat flour

Oat flour is claimed to be effective in muscle growth and energy replacement in depleted energy reserves.

A review in the Journal of Food Science and Technology provides that oat is a low cost protein source with high protein content of about 11 to 15%. According to the review, oat is beneficial for gluten allergy, lowering cholesterol, and cancerous activity.

ASTRAGIN

ASTRAGIN®

This ingredient is a combination of Astragalus membranaceus and the root extracts of Panax notoginseng.

In a research study in the Molecules journal, Astragalus membranaceus, (an herb used in traditional Chinese medicine) was found to increase endurance exercise capacity when combined with exercise training. It also reduced accumulation of blood lactate and ammonia, proving that it has anti-fatigue effects.

DigeZyme

DigeZyme®

This is an enzyme complex comprising of digestive enzymes such as amylase, cellulase, lactase, protease, and lipase. As we explain in our High Impact Plant Protein Reviews, It is specifically designed to aid in the digestion and absorption of nutrients from the foods we consume. By breaking down carbohydrates, proteins, fats, and fibres into smaller, easily digestible components, it helps alleviate digestive discomfort and bloating.

Studies in the Current Drug Metabolism journal provide that digestive enzymes break down proteins, carbohydrates, and lipids. In doing so, these enzymes may help manage digestive disorders, lactose intolerance, and cystic fibrosis.

How To Use Crazy Nutrition Mass Gainer?

Crazy nutrition mass gainer dosage is simple and flexible. Add 4 scoops of the powder to 300ml or 500ml of water, then shake or blend until smooth and enjoy. The shake can be taken any time of the day, whether for breakfast, lunch, dinner, or as a complete meal replacement when extra calories are needed.

For best results, use it consistently every day alongside a regular training routine. Avoid mixing with hot liquids, since high heat can affect the digestive enzymes. Store the bag in a cool, dry place away from direct sunlight to maintain freshness and effectiveness.

What Do the Crazy Nutrition Mass Gainer Customer Reviews Says?

Here’s what crazy nutrition mass gainer reviews says:

Great meal replacement!
Great product as I use it in between meals to get calories in and added protein. The only negative is if you live in the States, as I do, it takes extremely long to receive the product. I am currently at 18days since I ordered and it still has not arrived in the U.S. Hope they can get it to the U.S. distribution center soon so I don’t have to wait for it to go through customs. Love the product though! –Todd P.

Effective and Tasty
Been taking this a couple months ago in combination with working out using my new PowerBlock set. Up from the low 140s to around 150 in two and a half months. It’s been an easy way to get in the extra calories I had been missing to really put on mass –Ryan R.

Solid formula
I’ve tried a ton of gains formulas. This is my new favorite. Great ingredients. Digests easy. Easy to mix. I add bananas and peanut butter to mine and it’s awesome. –Trent R., Gainesville, FL

    Finally hit after years of struggling
    I’ve been stuck around 145 lbs since college. Tried every high-calorie diet and gagged on dry rice and chicken for months. Started Mass Gainer eight weeks ago and I m at 168 now. Way easier than choking down five meals a day. Mixes clean too. No bloating, no weird aftertaste. Worth every dollar
