Batteril 900 is a dietary supplement based on grapefruit seed extract and tea tree essential oil. Its blend of active components (called phytocomplexes) prevents bacteria from developing resistance to antibiotics (unlike conventional antibiotics). Grapefruit is a powerful natural antibiotic with a broad spectrum of action due to its richness in bioflavonoids (e.g., hesperidin) and vitamins (e.g., vitamin C) with antioxidant properties. It has the ability to neutralize 800 types of bacteria, viruses, and 100 types of fungi, while simultaneously preserving intestinal microflora (something that conventional antibiotics cannot do):

Antibacterial activity - Vitamin C has a specific action on the immune system, inhibiting the growth of pathogenic microorganisms. It is present in high concentrations in neutrophils (blood cells), thus stimulating their activity against microbial invasion. There is also evidence that supplementing the diet with vitamin C reduces the incidence, severity, and duration of flu symptoms. It also has the ability to act against the Helicobacter pylori bacteria, mitigating the effects of stomach ulcers and producing a calming effect on the stomach.

Antifungal activity - Vitamin C enhances the effects of the antibiotic amphotericin B on the fungus Candida albicans. Grapefruit is particularly beneficial during and after treatment, as it helps boost immune system activity and reduce the possibility of reinfection.

Protective activity - exerts a protective effect on ischemia/reperfusion-induced pancreatitis through antioxidant mechanisms in the pancreas and by improving pancreatic circulatory flow.

Tea Tree Oil - essential oil derived from the leaves of Melaleuca alternifolia. It is an excellent substitute for conventional antibiotics, as it has a good ability to prevent microbial resistance, giving it excellent antiseptic properties. It helps treat vaginal infections, fungal infections, eczema, respiratory problems including sore throats, coughs, asthma, and bronchitis, and combats various viruses such as chickenpox, flu, and measles. It is useful for ulcers as it disinfects, reduces pain, and aids in the healing process.
