Bêlisina Forte Bioregenerating Tonic was formulated to support the body during periods of increased physical, mental, or nutritional demand, providing essential nutrients that participate in various metabolic processes. L-lysine, an essential amino acid, is part of a formula enriched with B vitamins (B1, B2, B3, B5, B6, and B12), fundamental for normal energy metabolism and the functioning of the nervous system. Vitamin C contributes to the normal functioning of the immune system and helps reduce tiredness and fatigue, while Vitamin D participates in the maintenance of muscle function and the immune system. Iron contributes to the normal formation of red blood cells and hemoglobin, as well as to the normal transport of oxygen in the body, being particularly important in situations of increased nutritional need. The formula is also enriched with Coenzyme Q10, a compound naturally present in cells, involved in energy production processes. Presented as an oral solution, the product promotes rapid absorption of its components. It is indicated for adults experiencing physical or intellectual fatigue, convalescence, reduced food intake, restrictive diets, or other situations with increased nutritional needs. It contains no sugar or gluten.
