Calcium and Ketamine Therapy | Tovani Health
Calcium Carbonate (Calcium Supplement) (also: Calcium Citrate, Os-Cal, Caltrate) — Essential mineral supplement (bone health)
Verdict at Tovani Health
Fully compatible with KAP.
Calcium and ketamine have no clinically significant interaction. The well-known calcium-absorption interactions (levothyroxine, certain antibiotics, bisphosphonates) require timing those drugs separately from calcium — intrinsic, not a KAP issue.
If you take Calcium Carbonate 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 Calcium Carbonate interacts with ketamine
Calcium supplements provide elemental calcium for bone mineralization and many other roles. Chelation with some other oral drugs is a mechanical absorption issue, not a metabolic one. No CYP interaction with ketamine.
What we do at intake
Continue as normal. Follow your prescriber's timing instructions if you take levothyroxine, alendronate, or certain antibiotics.
Bottom line
Calcium and ketamine have no clinically significant interaction. The well-known calcium-absorption interactions (levothyroxine, certain antibiotics, bisphosphonates) require timing those drugs separately from calcium — intrinsic, not a KAP issue.
