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

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 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 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.

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.

This is an enzyme complex comprising of digestive enzymes such as amylase, cellulase, lactase, protease, and lipase.
