Vitamin B12 and Ketamine Therapy | Tovani Health

Cyanocobalamin (Vitamin B12) (also: Methylcobalamin, Hydroxocobalamin)Water-soluble vitamin

Verdict at Tovani Health

Fully compatible with KAP.

Vitamin B12 and ketamine have no clinically significant interaction. Common as supplement for low-B12, vegan/vegetarian diets, and metformin-related B12 depletion. Both oral and injectable forms are fine. Worth noting: recreational nitrous oxide use inactivates B12, so we screen for that separately.

If you take Cyanocobalamin regularly and are considering at-home ketamine therapy, the combination is generally safe at therapeutic doses. This page covers the brief pharmacologic context and what we do at intake.

How Cyanocobalamin interacts with ketamine

Vitamin B12 is essential for methylation reactions and DNA synthesis. No CYP interactions with ketamine.

What we do at intake

Continue as normal. Disclose any heavy nitrous oxide use (whippits) which can deplete B12.

Bottom line

Vitamin B12 and ketamine have no clinically significant interaction. Common as supplement for low-B12, vegan/vegetarian diets, and metformin-related B12 depletion. Both oral and injectable forms are fine. Worth noting: recreational nitrous oxide use inactivates B12, so we screen for that separately.
