Longan rich in vitamins and minerals such as: vitamin C – 93,3%, copper – 16,9%
- Vitamin C participates in redox reactions, the functioning of the immune system, promotes the absorption of iron. Deficiency leads to loose and bleeding gums, nosebleeds due to increased permeability and fragility of the blood capillaries.
- Copper is a part of enzymes with redox activity and involved in iron metabolism, stimulates the absorption of proteins and carbohydrates. Participates in the processes of providing the tissues of the human body with oxygen. The deficiency is manifested by disorders in the formation of the cardiovascular system and skeleton, the development of connective tissue dysplasia.
