Galdieria Blue™ by Fermentalg is the first phycocyanin obtained by fermentation. This breakthrough innovation offers two unique benefits: a stable natural blue colorant for food and beverages, and a 3 in 1 powerful antioxidant for nutrition, wellness, and beauty.
Born from years of biotechnological research, Galdieria Blue™ represents a new generation of natural ingredients derived
from the microalga Galdieria sulphuraria. It results in two pioneering BioSolutions authorized in the U.S.A.:


Both solutions are sustainably produced in Europe by fermentation, ensuring purity, traceability, and consistent performance and are authorized on the US market as of today.
Fermentalg’s Galdieria Blue™ is the first phycocyanin obtained by fermentation, derived from Galdieria sulphuraria FCC 3424, a unique extremophilic microalgae. This technological breakthrough combines purity and performance, opening new possibilities for innovation in health and nutrition.

Fermentalg offers Galdieria Blue™ from proprietary FCC3424 primarily in powder form, a versatile, high-purity format designed for efficacy, stability, and easy formulation. Its unique properties open a world of product innovations, from ready-to-drink concepts and functional blends to bright blue softgels.
Galdieria Blue™ Color, co-developed with Givaudan and marketed under the Everzure™ range, is a natural, acid-stable blue pigment derived from microalgae and matched in hue to Blue 1. It enables manufacturers to move from synthetic dyes to a clean-label, traceable alternative, a breakthrough especially for beverages, where natural blues were once out of reach.Unlike spirulina-derived pigments, Galdieria Blue™ offers excellent stability and a neutral taste, making it ideal for a wide range of food and beverage applications - from soft drinks and yogurts to confectionery and frozen desserts - bringing vibrancy, performance, and trust to every creation.


Oxidative stress is a major factor in the development and progression of many health issues. From intense exercise and UV exposure to pollution and aging, our cells are constantly under pressure. Galdieria Blue™ AOX helps restore the body’s inner balance with a next-generation 3-in-1 antioxidant that combines direct and indirect protection.
It neutralizes free radicals more effectively than olive and licorice extracts, targets superoxide radicals with three times higher scavenging activity than standard SOD sources, and stimulates cellular defenses by activating the Nrf2 pathway more strongly than leading botanical extracts.
Documented in scientific literature for use in a range of applications:

May promote balance, immunity, and overall wellness.

May support recovery, reduce oxidative stress, improve performance and joint comfort.

May protect cells, contribute to vitality, support cognitive and cardiovascular functions.

May help skin defend against oxidative stress, UV and pollution, reinforcing natural defenses and preserving skin integrity.
While phycocyanin has long been derived almost exclusively from Spirulina platensis, Fermentalg uncovered an extraordinary alternative: Galdieria sulphuraria.
Discovered in the early 80s in the steaming hot springs of Sonoma (USA), this extremophilic red microalga thrives where few organisms can survive. Naturally rich in phycocyanin, Galdieria stands out for its remarkable resilience, with pigments known for exceptional heat and acid resistance.
After years of pioneering research, Fermentalg developed a brand new phycocyanin from Galdieria thanks to a unique patented process - unveiling Galdieria Blue™ AOX, a next-generation natural blue pigment born from the power of extremophiles microalgae.

From microalgae strain to final extract, the entire production process is fully controlled by Fermentalg in Europe. Produced in sterile, closed fermenters with no exposure to environmental contaminants, Galdieria Blue™ is non-GMO, solvent-free, and manufactured according to the highest safety and sustainability standards.

Galdieria Blue™ is designed to meet the most demanding expectations of both manufacturers and consumers.
Beyond its antioxidant activity, it also offers the vibrancy of a rare natural blue pigment.
Safe for sensitive consumers.
Produced in Europe through controlled fermentation, without harvesting in nature.
Naturally obtained, without genetic modification.
Neutral in taste and odor, ensuring easy formulation
