Sodium Caseinate

Sodium Caseinate

Snapshot

Sodium Caseinate is a milk‑derived protein supplement that provides sustained amino acid release, supports muscle recovery and growth, enhances satiety, and promotes gut health through bioactive peptides.

What is Sodium Caseinate?

Sodium Caseinate is the sodium salt form of casein, the predominant protein in milk. It forms micelles in water, creating a slow‑digesting protein matrix that delivers amino acids gradually over several hours.

---

Where It Comes From

Derived from cow’s milk, casein is separated during cheese production, purified, and then neutralized with sodium hydroxide to form a water‑soluble salt. The resulting powder is spray‑dried for use in nutritional supplements and food formulations.

---

Key Nutrients & Compounds

Provides all essential amino acids with high levels of glutamine and proline. Bioactive peptides released during digestion exhibit immunomodulatory and antimicrobial activities.

---

Health Benefits

Sodium Caseinate delivers a prolonged release of amino acids that supports muscle protein synthesis and recovery; promotes feelings of fullness to aid weight management; and supplies peptides that may support gut barrier function and immune health.

---

Recommended Dosage

Typical dosing ranges from 20 g to 40 g per serving, taken once or twice daily. For muscle maintenance, consume 20–30 g before bedtime or between meals. Adjust based on individual protein requirements and total dietary intake.

---

How to Use It

Mix powder into water, milk, or smoothies. Stir briskly to avoid clumping. Consume on an empty stomach before sleep for overnight muscle support or between meals to curb appetite and stabilize blood amino acid levels.

---

Who Should Use It?

Ideal for athletes and active individuals seeking sustained muscle recovery, people aiming to increase daily protein intake, and those looking for a satiating protein source. Not suitable for individuals with milk protein allergies.

---

Possible Interactions or Cautions

May cause digestive discomfort in those with lactose intolerance or dairy allergies. Avoid combining high‑protein loads with creatine in a single dose to reduce gastrointestinal stress. Consult a healthcare provider if on low‑sodium diets due to added sodium content.

---

Final Thoughts

Sodium Caseinate is a slow‑release, high‑quality protein that supports muscle repair, satiety, and gut health. Its unique digestion profile makes it particularly suited for nighttime use and appetite control.
