Introduction: Caltron Clays & Chemicals Is Redefining Calcium with Plant-Based Precision
In the rapidly expanding nutraceutical market, one raw material is redefining how the world views calcium: algae-derived calcium. And when it comes to trusted sourcing in India, Caltron Clays & Chemicals is leading the charge. As a premium Algae Calcium Powder manufacturer and supplier in India, Caltron is bridging the gap between nature and science with its clinically supported, highly bioavailable, vegan-friendly product AL-g-CAL.
As nutraceutical brands, pharmaceutical companies, and wellness product manufacturers push for cleaner, plant-based ingredients, Caltron’s algae calcium offers a timely solution. In 2025, bone health isn’t just about calcium it’s about clean labels, absorption efficiency, trace minerals, and sustainability.
This blog dives into how Caltron is enabling India’s pharma and nutraceutical industries to deliver on that promise.
The Nutraceutical Boom: 2025 and Beyond
The global nutraceutical market is expanding at an unprecedented rate. With a projected value of over $500 billion by 2027, categories like bone and joint health, pediatric supplements, and geriatric care are among the most in-demand segments.
Yet within this boom, consumers are rejecting synthetic, chemical-bound calcium sources and turning toward bioavailable options. Key trends include:
- Plant-based ingredients: especially those with environmental and ethical advantages
- Bioavailability focus: not just what you consume, but what your body absorbs
- Multi-mineral synergy: not just calcium, but magnesium, zinc, silica, and boron
- Vegan and clean-label certifications: increasingly important for export-oriented brands
This shift creates a significant opportunity for Caltron’s algae calcium powder a solution that addresses all of these modern formulation priorities.
Algae Calcium: The Natural Evolution of Calcium Supplementation
Traditional calcium supplements including limestone-derived calcium carbonate and bone meal come with a range of challenges:
- Poor absorption, leading to residual buildup and kidney stress
- Not suitable for vegans or vegetarians
- Low trace mineral content
- Chemical processing and synthetics
Algae calcium, in contrast, is a breakthrough innovation:
- Extracted from marine algae species like Lithothamnion Calcareum and Chlorophyta
- Naturally porous and fibrous, aiding absorption
- Delivers over 74 trace minerals including magnesium, boron, silica, and zinc
- Certified vegan, non-GMO, and heavy-metal free
As demand for these qualities grows, Caltron’s AL-g-CAL stands out in the global market.
Meet AL-g-CAL: Caltron’s Signature Algae Calcium Powder
AL-g-CAL, developed by Caltron Clays & Chemicals, is more than just a raw material it’s a formulation solution. Backed by over two decades of mineral science expertise, Caltron has built this brand to rival the best global standards in calcium sourcing.
Key features of AL-g-CAL include:

Lithothamnion & Chlorophyta: Dual-Grade Advantage for Every Formulation
Caltron offers two algae-based grades to serve diverse B2B requirements:

- Ideal for osteoporosis prevention and geriatric formulas
2. Chlorophyta
