Quillaja extractSoapbark extract

Quillaja extract, derived from the Chilean soapbark tree, is a natural substance used in protein powders as an emulsifier and foaming agent. It helps to create a smooth texture and creamy protein shakes that are easier to consume.

Resveratrol

Resveratrol, a natural compound found in plants, is added to protein powders due to its potential health benefits, including improving heart health and reducing inflammation. It may also improve exercise performance and reduce muscle damage.

RetinolVitamin A

Retinol, a form of vitamin A found in animal-derived foods, is also available in synthetic form as a dietary supplement and is sometimes added to protein powders.

RiboflavinVitamin B2, Lactoflavin

Riboflavin, also known as Vitamin B2, is a water-soluble vitamin used in protein powders due to its ability to support energy metabolism and protect against oxidative stress.

RibonucleaseRNase

Ribonuclease is an enzyme that is sometimes added to protein powders to aid in the digestion and absorption of protein, potentially increasing the bioavailability of dietary protein and improving protein synthesis.

Ribose

Ribose is a naturally occurring sugar in the body that plays a role in energy metabolism. It is sometimes added to protein powders to help improve athletic performance and reduce muscle fatigue by increasing ATP production in the body.

Saccharin

Saccharin is a non-nutritive artificial sweetener used in some protein powders. It is much sweeter than sugar and helps reduce calorie and sugar intake.

Silicon dioxideSilica

Silicon dioxide is a natural compound found in quartz, sand, rocks, and soil. It is used as an anti-caking agent in protein powders to prevent clumping, and as a stabilizer and thickener in food products.

Sodium ascorbateVitamin C

Sodium ascorbate is a form of vitamin C that is added to protein powders to boost their nutritional value. It helps maintain a healthy immune system, supports collagen production, and acts as an antioxidant.

Sodium benzoate

Sodium benzoate is a common food preservative used in protein powders to extend shelf life by inhibiting bacterial and fungal growth.

Sodium carboxymethylcellulose

Sodium carboxymethylcellulose (CMC) is a food additive derived from cellulose that is added to protein powders as a thickener, stabilizer, and emulsifier. It improves texture, prevents clumping, and enhances stability.

Sodium caseinate

Sodium caseinate (otherwise known as casein) is a milk-derived protein that is often used in protein powders due to its high protein content. It is a slow-digesting protein that provides a sustained release of amino acids into the bloodstream.

Sodium chlorideSalt, Table Salt

Sodium chloride, or salt, is used in protein powders as a flavor enhancer and to maintain proper fluid balance and blood pressure.

Sodium citrate

Sodium citrate, a salt of citric acid, is used in protein powders to regulate pH, improve texture, and prevent spoilage.

Sodium metabisulfite

Sodium metabisulfite is a food preservative used in protein powders to prevent oxidation and extend shelf life.

Sodium phosphateMonosodium phosphate, Disodium phosphate, Trisodium phosphate

Sodium phosphate is a salt commonly used as a pH stabilizer and buffering agent in protein powders. It may also serve as a source of dietary phosphorus.

Sodium stearyl fumarate

Sodium stearyl fumarate is a food additive used in protein powders as a flow agent to prevent clumping and improve flow.

Sorbitan monostearate

Sorbitan monostearate is an emulsifier used in protein powders to stabilize the mixture and prevent separation. It also improves texture, giving a more creamy mouthfeel.

Spirulina

Spirulina is a blue-green algae used in protein powders for its high protein content and nutrient density, particularly for vegans and vegetarians. Potential benefits include improved immune function and reduced inflammation.

Steviol glycosideStevia

Steviol glycosides are a low-calorie sweetener extracted from Stevia rebaudiana plant leaves, commonly used in food and beverage products as an alternative to sugar for people with diabetes or watching their weight.
