Blue spirulina powder is a natural plant-based colourant derived from the blue phycocyanin pigment of spirulina algae. Unlike green spirulina, which is whole algae powder commonly used in smoothies and supplements, blue spirulina is focused on providing a vibrant blue colour for food and beverage applications. It blends easily into beverages, smoothies, baked goods, and confectionery, creating a clean-label, striking hue without altering flavour. Blue spirulina is ideal for creative and visually appealing formulations where natural colouring is desired.
