What natural blue options do you offer — gardenia or spirulina?

Nature's Flavors offers two plant-based blues, and the right one depends on your process.

• Our spirulina-based blue is a vibrant, algae-derived, economical blue — a great fit for frostings, icings, and cold beverages.

• Our gardenia-based blue delivers a vivid, true blue without synthetic dyes and holds its color through heat, acidity, and light. It is designed to stay true from production through shelf — the stronger choice for beverage and snow-cone syrups, hot-fill and heat-processed products, baked goods, and products displayed under bright light.

Both are plant-based and vegan with no synthetic dyes. For cold, neutral formulas, spirulina is a great, economical fit; for anything heat-processed, acidic, or light-exposed, gardenia is generally the better choice. We recommend testing both in your finished product to confirm the color.
