Why SPRU Has No Added Sugar or Preservatives

SPRU is made without added sugar or preservatives. We keep the recipe straightforward and use a frozen process to store the product.

Why we do not add sugar

We want SPRU to taste like spirulina, not a sweetened drink or snack. Leaving out added sugar keeps the product simple and avoids adding sugar to the recipe.

Why we do not add preservatives

After harvest, we wash the spirulina biomass, separate it by centrifuge, portion it and blast-freeze it at −18°C. We keep SPRU frozen through storage and delivery rather than adding preservatives to the product.

Made for the freezer

Put SPRU in the freezer when it arrives and keep it frozen until you are ready to use it. Do not store it in the fridge.

That is our product choice: fresh spirulina, no added sugar or preservatives, and frozen handling from production to your freezer. Learn about how SPRU is grown or see product care.
