Resfree from Nova Diet is a nutritional supplement indicated to alleviate the discomfort caused by flu and catarrhal states. Resfree is a nutritional supplement made up of medicinal plants, vitamins and minerals that have traditionally been used to boost the body's immune system. It is an extract rich in oleuropein, which in our body is converted into elenolic acid, which is the component that has been shown to have an antimicrobial effect. The mechanism of its antimicrobial action is being studied and different possibilities are being considered: - That it inactivates cellular enzymes that are essential for the replication of microorganisms; - That produces direct damage to the cell membrane, allowing intracellular components and nutrients to escape - That it interferes at a specific point in the production of amino acids, which directly affects the life cycle of viruses; - That directly stimulates phagocytosis in our immune system; - That causes an irreversible inhibition of viral replication. It is recommended to dissolve the content in a glass of water (100 ml), stir and drink before breakfast, lunch and dinner. • Not recommended for use during pregnancy and lactation. • Do not take this food supplement if you have hypersensitivity to Salicylates or if you have an allergy or intolerance to any of its ingredients. • It is recommended to take it with meals if there are stomach problems. • Its use is not recommended if you suffer from any autoimmune condition.
