At a glance
Summary
This protein powder contains high-quality protein sources like whey protein isolate and micellar casein, which are beneficial for muscle growth and recovery. However, the presence of artificial sweetener sucralose, along with carrageenan and cellulose gum, indicates a reliance on processed additives that detract from its overall healthfulness. The use of natural flavors and sunflower lecithin further contributes to a moderate level of processing, impacting the product's score.
Key ingredients 10
Whey Protein IsolateVery Good
Whey protein isolate is a high-quality protein source with a complete amino acid profile, beneficial for muscle growth and recovery. It is derived from milk and is highly bioavailable, making it an excellent choice for protein supplementation. Compared to other protein sources, it is low in lactose and fat, enhancing its digestibility.
Benefits
Rich in essential amino acids, it supports muscle repair and growth, and aids in weight management.
Micellar CaseinGood
Micellar casein is a slow-digesting protein that provides a sustained release of amino acids, making it ideal for prolonged muscle protein synthesis. It is minimally processed and retains its natural micellar structure, which enhances its nutritional quality. This protein is particularly beneficial for overnight recovery.
Benefits
Supports muscle maintenance and recovery over extended periods, especially beneficial when consumed before fasting periods like sleep.
Sea SaltGood
Beneficial ingredient — whole-food or functional value in this product class.
Risks
Excessive consumption can contribute to high blood pressure.
Benefits
Provides essential electrolytes that support hydration and nerve function.
Cellulose GumNeutral
Standard formulation ingredient — neither beneficial nor harmful at typical use.
Risks
May cause digestive discomfort in some individuals.
Silicon DioxideNeutral
Silicon dioxide is used as an anti-caking agent to prevent clumping in powdered products. It is generally recognized as safe and is inert in the body. Its presence is common in many food products to maintain texture.
Benefits
Helps maintain product texture and flowability without affecting nutritional content.
Steviol GlycosidesNeutral
Steviol glycosides are natural sweeteners derived from the stevia plant, offering sweetness without calories. They are minimally processed compared to artificial sweeteners. Their use is generally considered safe and does not significantly impact blood sugar levels.
Benefits
Provides a natural, zero-calorie sweetening option, suitable for those managing blood sugar levels.
Natural FlavorsBad
Natural flavors are a catch-all term for flavoring agents derived from natural sources but can be highly processed. The lack of transparency in their composition can be concerning for those with allergies or sensitivities. They do not provide nutritional benefits and can mask the quality of the product.
Risks
Potential allergen risk due to undisclosed ingredients and processing methods.
Sunflower LecithinBad
Sunflower lecithin is used as an emulsifier to improve texture and mixability in products. It is derived from sunflower seeds and is less processed than soy lecithin. Despite being a better alternative to soy lecithin, it still adds unnecessary processing to the product.
Risks
May cause digestive issues in sensitive individuals.
Benefits
Improves product consistency and mixability without significant health benefits.
CarrageenanBad
Carrageenan is a thickener and stabilizer derived from red seaweed, often linked to gastrointestinal inflammation. It is a controversial additive due to potential digestive health concerns. Its use in food products is debated due to these health implications.
Risks
Linked to gastrointestinal inflammation and discomfort.
SucraloseBad
Sucralose is an artificial sweetener used to provide sweetness without calories. It is highly processed and may affect gut health and insulin response. Its use is controversial due to potential long-term health effects.
Risks
May impact gut microbiota and insulin sensitivity.
Benefits
Provides sweetness without adding calories, beneficial for calorie-restricted diets.
