Naso B12 Nasal Spray 2.3ml is used for replenishing Vitamin B12 levels in the body, in its active form Methylcobalamin. It is essential in red blood cell production, nervous system maintenance, and energy metabolism. It is a specialised nasal formulation. This product benefits individuals with dietary, drug-induced, or absorption-related deficiencies of Vitamin B12. The nasal spray delivers the active ingredient directly into the bloodstream through the nasal mucosa, offering faster absorption than oral supplements. Its easy-to-use design ensures precise dosage and minimises the risk of gastrointestinal side effects often associated with oral Vitamin B12 supplements.
