In the crowded field of antioxidant ingredients, Astaxanthin has long been recognized as a powerhouse—renowned for its ability to cross the blood-brain barrier and neutralize free radicals more effectively than traditional antioxidants like vitamin E and green tea polyphenols. However, the ingredient's poor bioavailability has historically limited its full potential. INNOBIO's AstaGuard® Astaxanthin, powered by patented microencapsulation technology, is changing that.
Breaking Through Bioavailability Barriers
Astaxanthin's lipophilic nature makes it inherently difficult for the body to absorb. INNOBIO addressed this fundamental challenge through advanced microencapsulation techniques that protect the active compound and enhance its delivery. In simulated intestinal epithelial cell permeability studies, AstaGuard® Astaxanthin demonstrated a remarkable 11.35-fold increase in bioavailability compared to traditional non-encapsulated oil formulations.
The research, measuring apparent permeability coefficients of digestive end-products, confirms that microencapsulation not only shields the astaxanthin molecule from degradation but also facilitates its transport across the intestinal barrier—ensuring that more of this potent antioxidant reaches the cells where it is needed most.
Formulation Flexibility: Oil, Powder, Beadlets, and Emulsion
Recognizing that different applications demand different delivery forms, INNOBIO offers AstaGuard® Astaxanthin in multiple formats to suit diverse manufacturing needs. These include oil-based formulations, water-dispersible powders, stable emulsions, and an innovative beadlet technology specifically engineered for tablet compression.
The beadlets innovation addresses a longstanding industry challenge: discoloration and diffusion of astaxanthin during tablet pressing. AstaGuard® Astaxanthin Beadlets maintain color integrity and ingredient stability throughout the compression process, ensuring consistent dosing and aesthetic appeal in finished tablet products.
Two Extraction Methods for Application Versatility
AstaGuard® Astaxanthin is available in two extraction forms—solvent extraction and supercritical CO₂ extraction—allowing manufacturers to select the optimal grade based on application requirements, regulatory considerations, and target markets.
A New Standard for Astaxanthin Delivery
AstaGuard® Astaxanthin represents a significant leap forward in antioxidant ingredient technology. By combining the naturel potency of Haematococcus pluvialis-derived astaxanthin with INNOBIO's proprietary microencapsulation platform, the product achieves unprecedented levels of bioavailability, stability, and clinical efficacy. For formulators seeking to deliver true physiological benefits—whether for skin health, joint support, or systemic antioxidant protection—AstaGuard® offers a science-backed solution that performs as reliably in the body as it does on the production line.
