Spirulina de Retz
It's in this unspoilt environment, bathed in sunshine and sea air, that Spiruline de Retz flourishes. Marion and Hugo, committed craftsmen, grow their French farmhouse spirulina in the greenhouse in outdoor ponds, without pesticides, fungicides or insecticides.
The spirulina is dried at a low temperature, making it easy to add to your diet.
