Why SRBio Stands Out as Your L-Zinc Carnosine Supplier

Core Functional Advantages

1、Gastrointestinal Mucosa Targeting

Site-Specific Adhesion: Adsorbs to damaged gastric mucosa via electrostatic interaction, forming a protective barrier that lasts >6 hours (vs. 1-2 hours for ordinary zinc supplements).

Dual Mechanism:

Zinc: Promotes epithelial cell proliferation and collagen synthesis to accelerate mucosa repair.

Carnosine: Inhibits reactive oxygen species (ROS) and inflammatory factors (TNF-α) to reduce mucosa irritation.

2、 Formulation Compatibility & Stability

pH Adaptability: Stable in acidic environments (pH 1.2-3.0, typical gastric fluid); controlled release in neutral intestinal fluid (pH 6.8-7.4) to avoid systemic zinc overload.

Formulation Versatility: Compatible with:

Solid dosage forms (tablets, capsules, granules) — no discoloration or efficacy loss after 24 months of storage.

Liquid formulations (oral suspensions) — microencapsulated grade available to prevent sedimentation.

3、 Safety & Regulatory Compliance

Low Toxicity: LD₅₀ >5,000 mg/kg (rat, oral); no adverse effects in 12-month long-term toxicity studies.

Global Approvals:

Japan: Listed as a prescription drug ingredient for peptic ulcer treatment.

EU: Approved as a novel food ingredient (NF) for nutraceuticals.

China: Included in the “Catalog of Food Additives and Nutritional Fortifiers”.

Application Fields & Case Studies

1、 Pharmaceutical Industry

Indication: Adjuvant treatment of peptic ulcers, chronic atrophic gastritis.

Case: A Japanese pharmaceutical company launched a polaprezinc tablet (150mg/tablet) — clinical data showed 82% ulcer healing rate after 4 weeks (vs. 56% for placebo).

2、 Nutraceuticals

Product Types: Gastrointestinal care supplements, prenatal vitamins (to reduce gastric discomfort during pregnancy).

Case: A US nutraceutical brand formulated a “gastric-friendly” powder (20mg polaprezinc + 500mg glutamine) — 78% of users reported reduced post-meal bloating in 2 weeks.

3、 Functional Foods

Application: Gastric-friendly meal replacements, solid beverages for office workers (irregular diet).

Case: A Chinese food enterprise added 10mg polaprezinc per serving of oatmeal — product sales increased by 40% in 6 months (targeting “sub-healthy stomach” groups).
