Shaanxi Sigma Biotech delivers enterprise-grade Casein Phosphopeptide with proven mineral-binding properties. Our item highlights peptide substance ≥90% and atomic weight ≤1000Da, guaranteeing predominant bioavailability. Supported by 20 a long time of fabricating mastery and certified by ISO 9001, ISO 22000, FSSC 22000, HACCP, HALAL, and Legitimate, we keep up 10–20 tons security stock for reliable supply. With conveyance in 5–7 working days and full-process quality control—from crude fabric determination to last testing—you get solid, high-purity fixings that meet US FDA and EU compliance measures each time.

The item (CPP) is a bioactive peptide inferred through enzymatic hydrolysis of cow's drain casein. These little atomic peptides tie to basic minerals like calcium, press, and zinc, avoiding them from shaping insoluble compounds in your stomach related system.
This implies way better assimilation rates for your body.
You'll discover CPP progressively prevalent in useful nourishments and dietary supplements. Why? Since it addresses a common challenge: indeed when individuals expend sufficient minerals, their bodies regularly battle to retain them effectively.
Our CPP solves this problem naturally.

Our CPP contains phosphoserine buildups that shape dissolvable complexes with minerals. This keeps calcium and other supplements accessible for assimilation all through your stomach related tract—even in antacid conditions where they'd ordinarily precipitate.
You get maximum nutritional benefit from every dose.
We implement full-process quality monitoring:
Every shipment meets international food safety standards.
Your Casein Phosphopeptide formulations need to meet regulatory requirements worldwide. We've done the groundwork:
You can confidently develop products for any market.

Product development requires reliable partners. We maintain substantial inventory (10–20 tons of key products) and deliver within one week. No production delays. No reformulation panic.
Just consistent supply when you need it.
Our fine powder format (80-100 mesh) disperses easily in various formulations:
You'll appreciate the formulation versatility.
CPP significantly improves calcium bioavailability—studies show increases of 70% or more compared to calcium alone. This benefit extends to iron, zinc, and magnesium too.
Your customers get more nutritional value from their supplements.
By improving calcium absorption and retention, our peptide complex helps:
It's a science-backed approach to skeletal wellness.
Unlike some mineral supplements that cause stomach discomfort, CPP promotes absorption without irritation. The small molecular weight (≤1000Da) means easy digestion and minimal side effects.
Better compliance from your end users.

Q:How does the product boost mineral absorption?
A:CPP contains phosphorylated serine buildups that tie to minerals like calcium, press, and zinc. These solvent complexes stay bioavailable all through assimilation, avoiding mineral precipitation in antacid intestinal situations. This altogether increments the sum of minerals your body can really retain and utilize.
Q:What are the bone wellbeing benefits?
A:By progressing calcium assimilation rates, our peptide complex makes a difference increment bone mineral thickness. Customary admissions bolsters skeletal quality, diminishes break chance, and may offer assistance avoid osteoporosis—especially imperative for postmenopausal ladies, elderly people, and developing children who have higher calcium needs.
Q:What's the source of your crude materials?
A:We source high-quality new cow's drain casein from standardized, controlled dairy ranches. These offices keep up strict quality controls and creature welfare benchmarks. The casein experiences controlled enzymatic hydrolysis to create bioactive peptides with ideal atomic weight and mineral-binding capacity.
Q:Can I ask item samples?
A:Absolutely. We give free tests so you can assess quality some time recently committing to bigger orders. Contact us with your shipping data, and we'll orchestrate test conveyance promptly.
Q:What's your least arrange quantity?
A:We oblige different arrange sizes to back both small-scale item advancement and large-scale fabricating. Contact our group to talk about your particular amount prerequisites and get a customized cite.
