Summary

This mass gainer contains beneficial ingredients like whey protein isolate and creatine monohydrate, which support muscle growth and recovery. However, the presence of maltodextrin, a high glycemic index carbohydrate, and sucralose, an artificial sweetener, detracts from its overall healthiness. Additionally, the use of soy lecithin as an emulsifier adds to the processing level, impacting the score.

Key ingredients 19

Whey Protein Isolate
Very Good

Whey protein isolate is a highly refined protein source with minimal lactose and fat, offering a rich supply of essential amino acids. It is rapidly absorbed, making it ideal for post-workout recovery. Its high bioavailability supports muscle synthesis effectively.

Risks

May cause digestive discomfort in those with lactose intolerance, though typically less than other dairy proteins.

Benefits

Promotes muscle recovery and growth due to its high bioavailability and amino acid content.

Creatine Monohydrate
Very Good

Creatine monohydrate is a well-researched supplement known for enhancing strength and muscle mass. It increases phosphocreatine stores in muscles, improving high-intensity exercise performance. It is one of the most effective supplements for athletes.

Risks

May cause water retention and gastrointestinal discomfort in some individuals.

Benefits

Enhances strength, power, and muscle mass, particularly in high-intensity activities.

Organic Ground Oats
Good

Organic ground oats are a whole grain source of carbohydrates, providing sustained energy and fiber. Being organic, they are less likely to contain pesticide residues. They also contribute to digestive health and satiety.

Benefits

Rich in fiber and essential nutrients, supporting heart health and digestion.

Milk Protein Isolate
Good

Milk protein isolate is a high-quality protein source rich in essential amino acids. It is derived from milk and provides a complete amino acid profile. This ingredient supports muscle repair and growth.

Risks

May cause digestive issues in individuals with lactose intolerance.

Benefits

Supports muscle growth and repair due to its complete amino acid profile.

Whey Protein Concentrate
Good

Whey protein concentrate is a less processed form of whey protein, retaining more beneficial nutrients like immunoglobulins. It provides a balanced amino acid profile for muscle support. It is cost-effective and widely used in protein supplements.

Risks

Contains lactose, which may cause issues for lactose-intolerant individuals.

Benefits

Supports muscle growth and immune function due to its nutrient-rich profile.

L-Leucine
Good

L-Leucine is a branched-chain amino acid (BCAA) crucial for muscle protein synthesis. It plays a significant role in muscle recovery and growth. As an essential amino acid, it must be obtained through diet or supplementation.

Risks

Excessive intake may lead to imbalances in amino acid levels.

Benefits

Enhances muscle protein synthesis and supports recovery post-exercise.

Glutamine Peptides
Good

Glutamine peptides are a stable form of the amino acid glutamine, which supports immune function and gut health. They are more easily absorbed than free-form glutamine. This ingredient is beneficial for recovery and maintaining muscle mass.

Benefits

Supports immune health and muscle recovery, particularly during intense training.

MCT
Good

MCT (Medium Chain Triglycerides) are fats that are rapidly absorbed and used for energy, supporting weight management and cognitive function. They are derived from coconut or palm oil and are popular in ketogenic diets. MCTs provide a quick energy source without being stored as fat.

Risks

Excessive intake may cause digestive discomfort.

Benefits

Provides quick energy and supports metabolic health and cognitive function.

HMB
Good

HMB (Beta-Hydroxy Beta-Methylbutyrate) is a metabolite of leucine that helps reduce muscle breakdown and supports muscle growth. It is beneficial for athletes and those undergoing intense training. HMB is particularly effective in preserving muscle mass during calorie restriction.

Benefits

Reduces muscle breakdown and supports muscle growth and recovery.

ALA
Good

ALA (Alpha Lipoic Acid) is an antioxidant that helps reduce oxidative stress and supports metabolic health. It is involved in energy metabolism and may improve insulin sensitivity. ALA is beneficial for overall health and wellness.

Risks

High doses may cause gastrointestinal discomfort.

Benefits

Reduces oxidative stress and supports metabolic health.

DigeZyme Multi-Enzyme Complex
Good

DigeZyme is a blend of digestive enzymes that aid in the breakdown of proteins, carbohydrates, and fats. It enhances nutrient absorption and supports digestive health. This complex is beneficial for individuals with digestive issues.

Benefits

Improves digestion and nutrient absorption, supporting overall digestive health.

LactoSpore
Good

LactoSpore is a probiotic strain of Bacillus coagulans that supports gut health and immune function. It is stable and survives stomach acid, making it effective in delivering benefits. Probiotics are beneficial for maintaining a healthy gut microbiome.

Benefits

Supports gut health and boosts immune function.

Chromium
Good

Chromium picolinate is a mineral that enhances insulin sensitivity and supports glucose metabolism. It is often used in supplements for weight management and metabolic health. Chromium is essential for maintaining normal blood sugar levels.

Risks

Excessive intake may lead to kidney or liver damage.

Benefits

Supports glucose metabolism and may aid in weight management.

CLA Powder
Neutral

CLA (Conjugated Linoleic Acid) is a fatty acid found in meat and dairy that may support fat loss and improve body composition. Its effects are modest and vary among individuals. It is often included in weight management supplements.

Risks

High doses may lead to insulin resistance and increased liver fat.

Benefits

May aid in reducing body fat and improving lean muscle mass.

Flavouring
Neutral

Flavouring is used to enhance the taste of the product, but its composition is not specified. It may include natural or artificial components. Without specific details, it is considered neutral.

Risks

Potential for artificial components if not specified as natural.

Benefits

Improves palatability of the product.

HICA
Neutral

HICA (Alpha-Hydroxy Isocaproic Acid) is a leucine metabolite that may support muscle growth and recovery. Its effects are less studied compared to other leucine derivatives. It is included in some sports supplements for potential anabolic effects.

Risks

Limited research on long-term effects.

Benefits

May support muscle growth and recovery, though evidence is limited.

Maltodextrin
Bad

Maltodextrin is a highly processed carbohydrate with a high glycemic index, which can cause rapid spikes in blood sugar levels. It is often used as a filler or thickener in processed foods. Excessive consumption may lead to insulin resistance over time.

Risks

High glycemic index may contribute to blood sugar spikes and insulin resistance.

Benefits

Provides quick energy, which can be beneficial during intense physical activity.

Emulsifier
Bad

Soy lecithin is a common emulsifier used to improve texture and mixability in products. It is derived from soybeans and may contain trace amounts of allergens. While generally safe, it is a processed ingredient.

Risks

May contain soy allergens and is a processed ingredient.

Benefits

Improves texture and consistency of the product.

Sweetener
Bad

Sucralose is an artificial sweetener used to provide sweetness without calories. It is highly processed and may alter gut microbiota. While generally recognized as safe, its long-term effects are still debated.

Risks

May impact gut microbiota and has potential long-term health concerns.

Benefits

Provides sweetness without adding calories.
