Thalassiosira weissflogii is one of the most extensively used microalgae in aquaculture. It is a rich source of both valuable ω-3 fatty acids EPA and DHA, but also phytosterols. In addition, it contains high levels of carotenoids/antioxidants such as fucoxanthin and beta-carotene.

ThalaPrime W consists of Thalassiosira weissflogii that is produced under the most stringently controlled conditions (HACCP and FCA certified by SGS (FCA certificate BE 01/1522.GF)). Thalassiosira weissflogii produced at Proviron accumulates high levels of the ω-3 poly-unsaturated fatty acids eicosapentaenoic acid and docosahexaenoic acid (DHA) present in a readily bioavailable form. 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.
