Some people in some cases mismetabolize the naturally occurring glutamine in bone broth. This is the case of people who have intestinal dysbiosis, people who have deficiencies or who have been exposed to monosodium glutamate (or synthetic glutamine). If you do not feel well while consuming Mon Bouillon (absences, agitations, nausea, diarrhoea, vomiting, constipation, skin rashes, itching), consult your doctor.
