Description

Calcium Bis(2-Hydroxy-4-(Methylthio)Butyrate) is a high-purity, organically-bound calcium source designed for superior bioavailability and stability in demanding formulations. This compound matters because it provides a highly soluble and bioavailable form of calcium, crucial for applications where mineral absorption and compatibility are paramount. It is primarily needed by manufacturers in the animal nutrition, pharmaceutical, and high-end food supplement industries seeking a reliable and effective calcium supplement.

Application

• Animal Feed Additive: A key source of bioavailable calcium and methionine hydroxy analogue (MHA) for poultry, swine, and aquaculture feed to support bone development, eggshell quality, and overall metabolic function.
• Pharmaceutical Intermediates: Serves as a critical precursor or active ingredient in the synthesis of specialized calcium supplements and therapeutic formulations.
• Nutraceuticals & Dietary Supplements: Used in human-grade calcium supplements, functional foods, and beverages due to its enhanced absorption profile compared to inorganic calcium salts.
• Veterinary Products: Incorporated into mineral premixes and liquid supplements for livestock and companion animals.
• Research & Development: Utilized in biochemical and nutritional studies as a standardized source of organic calcium.

Quality Control

Our Calcium Bis(2-Hydroxy-4-(Methylthio)Butyrate) is manufactured under a strict quality management system. Each batch undergoes rigorous testing to ensure it meets precise specifications for purity, identity, and heavy metal content. Certificates of Analysis (COA) documenting compliance with relevant feed and food-grade standards are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture and caking.
