Overview
•Vitamin B12 forms (methylcobalamin and adenosylcobalamin) are well-tolerated with no established upper intake limit; 1000μg dosage is safe and commonly used in supplements without toxicity risks.
•No significant drug interactions reported for this formulation, though high doses may mask folate deficiency; consult physician if on medications like metformin or proton pump inhibitors.
•Safe for healthy adults, including vegans, but not recommended for children under 18 as per label; efficacy in elderly with absorption issues is supported by sublingual-like high dosing.
•Low risk during pregnancy or breastfeeding at this dose, but consult healthcare professional; no contraindications for common conditions beyond rare hypersensitivity to B12.
•Vegan tablets with no major allergens; inactive ingredients (cellulose, magnesium stearate) pose minimal contamination risks when manufactured in the UK under GMP standards.
•Long-term use is safe due to water-soluble nature, with excess excreted; rare side effects like mild diarrhea possible but unlikely at 1000μg.
