NannoPrime - Premium pathogen free freeze dried Nannochloropsis sp. ('Japanese Chlorella')

Nannochloropsis sp. is one of the most extensively used microalgae in aquaculture. Besides having EPA as important ω-3 fatty acid, Nannochloropsis sp. is also a rich source of pigments such as β-carotene, violaxanthin and zeaxanthin.

NannoPrime consists of Nannochloropsis sp. that is produced under the most stringently controlled conditions (HACCP and GMP certified (FCA certificate BE 01/1522.GF)). It is freeze dried according to a proprietary process to yield a premium grade product with the longest shelf life, no nutrient leakage, maintenance of the correct lipid profiles and an ensured bioavailability of ω-3 poly-unsaturated fatty acids.

NannoPrime offers:

  • Optimal nutrient profile: High levels of the ω-3 poly-unsaturated fatty acid eicosapentaenoic acid (EPA), vitamins and pigments such as β-carotene, violaxanthin and zeaxanthin.
  • Single Cell dispersion: Excellent for Green Water Technique thanks to the small single cell dispersion. NannoPrime exhibits the same characteristics as live Nannochloropsis and remains in the water column for very long periods.
  • Gut development: Gives the larvae a head start by activating the digestive system.
  • Pathogen free:  No sourcing from natural salt water. No fish, shrimp, shellfish or other aquatic organisms (pathogen vectors) grown in the vicinity of our production. Constant biological monitoring.
  • Long shelf life: NannoPrime can be stored for 36 months in normal conditions. It does not need to be frozen or cooled.
