Many studies carried out by the Biology Department of Cagliari University, showed that mullet roe bottarga is very rich in Omega3, therefore rich in good cholesterol.

Unlike other animals' eggs, fish eggs contain a high quantity of Omega3 polyunsaturated fatty acids (EPA and DHA), acids that nutritionists consider as important for a balanced diet and valid allies in the prevention of heart diseases. 

Some studies have shown that even after being processed (salted and dried) the eggs keep all their nutritional components unchanged.  

Among the other benefits of bottarga is the improvement of mental and physical fitness. Furthermore, many consider it a powerful aphrodisiac food.
