Mumbai, India — Caltron Clays & Chemicals Pvt. Ltd., a Mumbai-based pharmaceutical raw material manufacturer, continues to strengthen its position as a trusted supplier of marine-sourced calcium and magnesium ingredients for the global pharmaceutical and nutraceutical industries. With more than two decades of experience in mineral processing and natural ingredient sourcing, the company is widely recognized for delivering high-purity, bioavailable, and sustainably sourced raw materials that meet evolving formulation standards.
As demand for clean-label, naturally derived, and highly absorbable minerals continues to rise, Caltron Clays & Chemicals Pvt. Ltd. has focused its portfolio on three key marine-origin products: AQUACAL (Coral Calcium Powder), MARINCAL (Oyster Shell Calcium Carbonate Powder), and MARINMAG (Marine Magnesium Powder). These ingredients are increasingly being adopted by pharmaceutical manufacturers developing bone health supplements, joint care formulations, muscle support products, and preventive healthcare solutions.
Responding to the Global Shift Toward Natural and Sustainable Ingredients
The pharmaceutical and nutraceutical sectors are undergoing a major shift toward natural sourcing, traceability, and sustainability. Regulatory expectations, consumer awareness, and scientific research are driving manufacturers to move away from synthetic mineral salts toward naturally occurring sources that offer superior bioavailability and physiological compatibility.
Caltron Clays & Chemicals Pvt. Ltd. has aligned its manufacturing philosophy with this transition by investing in marine-based mineral sourcing and advanced purification processes. The company’s approach focuses on preserving the natural mineral structure while ensuring compliance with stringent pharmaceutical-grade quality standards.
According to industry experts, marine-derived calcium and magnesium are increasingly preferred due to their balanced mineral composition, better absorption profiles, and lower gastrointestinal side effects when compared to conventional synthetic alternatives. Caltron’s product portfolio directly addresses these market requirements.
AQUACAL Coral Calcium Powder: Supporting Bone Health Through Natural Bioavailability
AQUACAL Coral Calcium Powder is one of Caltron’s flagship offerings and represents the company’s commitment to natural, high-performance mineral ingredients. Derived from marine coral sources, AQUACAL provides calcium in a form that closely resembles the mineral composition found in the human skeletal system.
Calcium plays a critical role in bone mineral density, tooth strength, nerve signaling, and muscle contraction. However, the effectiveness of calcium supplementation largely depends on absorption efficiency. AQUACAL is known for its high bioavailability, making it suitable for pharmaceutical formulations targeting osteoporosis prevention, bone regeneration, and age-related bone loss.
Caltron follows controlled sourcing and processing practices to ensure the coral-derived calcium remains pure, consistent, and free from harmful contaminants. Each production batch undergoes extensive laboratory testing to validate mineral content, particle size distribution, and absorption potential.
AQUACAL is commonly used in dietary supplements, multivitamin-mineral formulations, chewable tablets, capsules, and bone-health blends designed for elderly populations, postmenopausal women, and individuals with calcium deficiency.
As a Coral Calcium Powder manufacturer in India, Caltron Clays & Chemicals Pvt. Ltd. supplies AQUACAL to pharmaceutical and nutraceutical companies across domestic and international markets, supporting product innovation with a reliable marine-based calcium source.
MARINCAL Oyster Shell Calcium Carbonate Powder: A Sustainable Calcium Solution
MARINCAL Oyster Shell Calcium Carbonate Powder represents another cornerstone of Caltron’s marine mineral portfolio. Produced from carefully selected oyster shells, MARINCAL offers a naturally occurring, renewable source of calcium carbonate that meets pharmaceutical-grade specifications.
Oyster shell calcium carbonate has long been valued in healthcare formulations due to its stability, cost-effectiveness, and high elemental calcium content. MARINCAL is processed through a series of cleaning, calcination, and micronization steps to achieve uniform particle size and consistent purity.
The product is widely used in calcium supplements, antacid formulations, food fortification applications, and nutraceutical blends. Its natural origin and proven safety profile make it suitable for long-term consumption and preventive healthcare products.
Sustainability plays a central role in MARINCAL production. Caltron sources oyster shells from responsible suppliers and fisheries, ensuring minimal environmental impact and promoting resource reuse. This aligns with global sustainability goals while offering manufacturers a dependable raw material solution.
As an established Oyster Shell Calcium Carbonate Powder supplier in India, Caltron supports pharmaceutical companies seeking scalable, compliant, and environmentally responsible calcium ingredients.
MARINMAG Marine Magnesium Powder: Enhancing Muscle, Nerve, and Metabolic Health
In addition to calcium, magnesium is an essential mineral involved in more than 300 biochemical processes in the human body. MARINMAG Marine Magnesium Powder is Caltron’s response to the growing demand for high-absorption magnesium sources in pharmaceutical and nutraceutical formulations.
Derived from marine environments, MARINMAG offers superior bioavailability and compatibility with calcium-based formulations. Magnesium plays a vital role in muscle relaxation, nerve transmission, cardiovascular function, electrolyte balance, and bone metabolism. Deficiency in magnesium is often linked to muscle cramps, fatigue, irregular heartbeat, and impaired calcium utilization.
Caltron ensures MARINMAG is sourced from clean marine regions and processed under controlled conditions to maintain mineral integrity. The powder is widely used in supplements targeting muscle recovery, sports nutrition, stress management, heart health, and bone support.
MARINMAG is frequently formulated alongside calcium products to improve overall mineral absorption and therapeutic effectiveness. As a Marine Magnesium Powder supplier in India, Caltron Clays & Chemicals Pvt. Ltd. provides pharmaceutical manufacturers with a reliable magnesium source that meets international quality standards.
Quality Assurance and Regulatory Compliance
Quality assurance is a defining aspect of Caltron’s operations. The company maintains strict internal quality control protocols at every stage of sourcing, processing, and packaging. Each batch of AQUACAL, MARINCAL, and MARINMAG is tested for purity, consistency, microbiological safety, and heavy metal compliance.
Caltron’s manufacturing facilities are equipped with modern processing technology and operate in alignment with global pharmaceutical and nutraceutical quality expectations. The company emphasizes documentation, traceability, and consistency to support regulatory submissions and audits for its customers.
This rigorous quality framework enables pharmaceutical brands to confidently integrate Caltron’s marine minerals into regulated formulations without compromising safety or performance.
