Key ingredients 7

Ion Exchange Whey Protein Isolate
Very Good

Ion exchange whey protein isolate is a high-quality protein source with a complete amino acid profile. It is processed to remove fats and lactose, making it suitable for those with lactose intolerance. This form of whey protein is rapidly absorbed, supporting muscle recovery and growth.

Benefits

Provides essential amino acids necessary for muscle repair and growth.

Microfiltered Whey Protein Isolate
Very Good

Microfiltered whey protein isolate is a premium protein source with minimal processing, retaining more bioactive compounds. It is low in fat and carbohydrates, making it ideal for lean muscle gain. The microfiltration process preserves the protein's natural structure, enhancing its nutritional value.

Benefits

Supports muscle recovery and provides a rich source of essential amino acids.

Vitamin/Mineral/Amino Acid Blend
Good

This blend includes essential vitamins and minerals that support overall health and well-being. The inclusion of amino acids like taurine and l-glutamine aids in muscle recovery and immune function. The blend is designed to complement the protein content, enhancing the product's nutritional profile.

Benefits

Enhances the nutritional value of the protein powder by providing essential micronutrients.

Soy Lecithin
Bad

Soy lecithin is used as an emulsifier to improve texture and mixability. It is derived from soybeans, which may be genetically modified and can cause allergic reactions in sensitive individuals. While it is not a seed oil, it is still a processed additive with potential allergenic concerns.

Risks

May cause allergic reactions in individuals sensitive to soy.

Benefits

Improves the mixability and texture of the protein powder.

Risks

May contain 4-MEI, a compound linked to cancer in animal studies.

Benefits
