Invyncible is a telemedicine provider network, not a pharmacy

Medication Interactions: Certain medications, like proton pump inhibitors and metformin, may interfere with B12 absorption

Dosage, Concentration, Route of Administration Dosage: Seek advice from a licensed physician, medical director, or other healthcare provider Concentration: 5mg/ml Route of Administration: IV/IM/SQ Resources: Precautions/Side Effects Some medications, supplements, or over-the-counter drugs may interact with methylcobalamin

Unlike synthetic B12 forms, methylcobalamin is ready for the body to use immediately and does not require conversion

In such cases, B12 injections bypass the gastrointestinal tract, directly increasing vitamin levels and helping alleviate symptoms like fatigue and neurological issues

Vitamin B12 has proven to be safe for most people, even in large doses
