How it works
Cyanocobalamin is converted in the body to active forms of B12, which act as coenzymes in critical metabolic pathways. These pathways are essential for DNA synthesis, red blood cell formation, and the maintenance of healthy nerve cells.
Who should take it
Adults looking to address brain fog, memory decline, attention difficulty. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.
Avoid / careful
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.

FAQs
Frequently asked
How long does it take to see effects?
Noticeable cognitive effects are typically observed within 2-8 weeks of consistent daily use.
Can I take this with other supplements?
Yes, cyanocobalamin can be layered into a broader protocol. Consult your clinician if you are on prescription medications affecting similar pathways.
What is the difference between Cyanocobalamin and Methylcobalamin?
Cyanocobalamin is a synthetic, stable form that requires conversion in the body. Methylcobalamin is an active form that is directly usable but less stable.
