Overview
Blue Spirulina Powder is a 1 ounce jar of phycocyanin extract sold as a natural blue food coloring, meant for smoothies, baked goods and energy bars. It is plant based and sized as a small trial jar rather than a bulk supply.
Phycocyanin is the pigment compound extracted from spirulina algae that gives foods a vivid blue tint without synthetic dye. At 1 ounce the jar suits testing a recipe or coloring occasional batches rather than daily production use. With no listed flavor or sweetener, it is meant to be blended into other ingredients rather than eaten alone.

Who it's for
Home bakers and smoothie makers who want a plant based blue coloring instead of an artificial dye. Not for anyone shopping this as a general spirulina nutrition supplement, since the listing centers on color rather than dosage or nutrient claims.
Strengths and trade-offs
Drawn from this product's published specifications.
- Plant based coloring alternative to synthetic dye
- Small jar suits occasional recipe use
- No added flavor to interfere with other ingredients
- No dosing or usage guidance given
- 1 ounce runs out quickly for regular bakers
- No stated shelf life or storage instructions
Performance notes
Phycocyanin colors food by dispersing into liquid or batter, and results depend on how much liquid it is blended into and the base color of the recipe. The listing gives no guidance on scoop amount per recipe, so getting a consistent shade takes some trial batches.
