Masstick is made with the freshest and highest quality ingredients. The blend consists mainly of shrimp (Palaemonetes varians) that we produce ourselves, harvested in the “Veta La Palma” Natural Space, and which are immediately freeze-dried to maintain optimum nutritional value. Freeze-dried microalgae and macroalgae are also added to the blend to satisfy the nutritional needs of a wide variety of marine fish.
