30 gr vacuum-packaged bag. A bag of 30 gr allows to make a cure of 10 days, at the rate of 3 grs per day (a large teaspoon) in order to allow you to test the form of spirulina that you prefer. The recommended duration of a cure is at least 1 month. The flakes can be eaten in different ways: you can put them in a yogurt, on your plate of raw vegetables or soup (not too hot). Avoid cooking spirulina (loss of quality ...). Enjoy!
