Sodium Caseinate Overview
What Is Sodium Caseinate
Sodium Caseinate is a protein that comes from milk. People make it by mixing casein with sodium hydroxide. This turns casein into a powder that can mix with water. The powder is white or yellow and melts in water fast. Casein has alpha, beta, and kappa caseins. These join with calcium and phosphorus to make clusters. When acid or rennet is added, casein leaves the milk. After adding sodium hydroxide, Sodium Caseinate is ready for food.
This ingredient mixes well with water but not with alcohol. Its pH is neutral, so it is safe for most foods. Food makers use Sodium Caseinate to make food feel better and add protein. You can find it in baked goods, dairy foods, drinks, and even in cosmetics. To make it, people mix casein with water, add sodium hydroxide, and dry it into powder.
Note: Sodium Caseinate is made from milk. People with milk allergies should always check food labels.

Nutrition and Supplements
Protein Drinks
Protein drinks help people get more protein each day. Many brands add sodium caseinate because it has lots of protein, about 88%. This ingredient mixes well with water, so shakes are easy to make. How well sodium caseinate dissolves depends on pH. It works best in drinks that are either acidic or alkaline, but not near pH 4.0–5.0. When mixed with other milk proteins, sodium caseinate helps the powder dissolve faster. This makes the drink smooth and without lumps.
Sodium caseinate also stops casein micelles from sticking together. This helps the powder mix better in drinks. When companies use dry-blending, sodium caseinate can help milk protein powders dissolve up to 97.5%. This means the drink will have a steady texture and lots of protein. People who drink these get more protein in every serving.
Tip: For best results, mix protein drinks with sodium caseinate in water or milk at the right temperature.
Dietary Supplements
Dietary supplements often have sodium caseinate to help give important nutrients. This protein acts as a carrier and stabilizer for fat-soluble vitamins like vitamin A. It forms a shell around the vitamin to keep it safe from light and air. This helps the vitamin stay strong and last longer in the supplement.
Studies show sodium caseinate helps the body take in more vitamin A. It forms complexes that protect the vitamin in the stomach’s acid. In lab tests, these complexes help more vitamin A reach the body’s cells. Modified sodium caseinate can hold even more vitamin A, making the supplement better. The natural structure of this protein helps it carry and protect other nutrients too.
