Summary
This protein powder contains high-quality whey protein isolate and concentrate, which are beneficial for muscle repair and growth.

While the product is relatively clean compared to other mass-market blends, the use of artificial sweeteners and processed additives impacts its score.
Key ingredients 10
Whey Protein IsolateVery Good
Whey protein isolate is a high-quality protein source with a complete amino acid profile, making it ideal for muscle repair and growth. It is processed to remove most fats and carbohydrates, resulting in a high protein content. Compared to other protein sources, it is rapidly absorbed and utilized by the body.
Benefits
Provides essential amino acids that support muscle recovery and growth.
Whey Protein ConcentrateGood
Whey protein concentrate is a high-quality protein that contains a range of essential amino acids. It is less processed than isolate, retaining more beneficial nutrients like immunoglobulins and lactoferrin. It is a cost-effective protein source with a slightly higher fat and carbohydrate content than isolate.
Risks
May contain lactose, which can be problematic for individuals with lactose intolerance.
Benefits
Supports muscle growth and recovery with a rich amino acid profile.
SaltNeutral
Salt is used to enhance flavor and preserve food. In moderate amounts, it is essential for maintaining fluid balance and nerve function. However, excessive consumption can lead to health issues such as hypertension.
Risks
Excessive intake may contribute to high blood pressure and cardiovascular issues.
Benefits
Essential for maintaining electrolyte balance and proper muscle function.
Xanthan GumNeutral
Xanthan gum is a common food additive used as a thickening and stabilizing agent. It is produced through the fermentation of sugars by the Xanthomonas campestris bacterium. It is generally recognized as safe when consumed in typical amounts found in food products.
Risks
May cause digestive discomfort in sensitive individuals when consumed in large amounts.
Benefits
Helps improve texture and consistency of food products.
Cellulose GumNeutral
Cellulose gum is a thickening agent derived from cellulose, a natural component of plant cell walls. It is used to stabilize and thicken food products. It is considered safe for consumption and is not absorbed by the body.
Benefits
Improves texture and stability of food products without adding calories.
Guar GumNeutral
Guar gum is a natural thickening agent derived from guar beans. It is used to improve the texture and consistency of food products. It is generally recognized as safe and can aid in digestion by acting as a soluble fiber.
Risks
Excessive consumption may lead to digestive issues such as gas and bloating.
Benefits
Acts as a soluble fiber, potentially aiding in digestion and satiety.
Silicon DioxideNeutral
Silicon dioxide is used as an anti-caking agent to prevent clumping in powdered products. It is naturally occurring and considered safe for consumption in small amounts. It does not contribute any nutritional value.
Benefits
Helps maintain the free-flowing nature of powdered products.
Natural FlavorsBad
Natural flavors are a catch-all term for flavoring agents derived from natural sources but can be heavily processed. The lack of transparency in their composition can be concerning for consumers seeking clean labels. They may contain additives or solvents used in the extraction process.
Risks
Potential for undisclosed additives or allergens.
Sunflower LecithinBad
Sunflower lecithin is an emulsifier derived from sunflower seeds. While it is less processed than soy lecithin, it is still considered a processed additive. It is used to improve texture and mixability in food products.
Risks
May contain trace amounts of solvents used in extraction.
Benefits
Can improve the texture and mixability of food products.
SucraloseBad
Sucralose is an artificial sweetener used to provide sweetness without calories. It is chemically altered to be non-caloric and is much sweeter than sugar. Concerns exist about its potential impact on gut health and insulin response.
Risks
May affect gut microbiota and insulin sensitivity in some individuals.
Benefits
