Alpha-Glyceryl Phosphorylcholine (Alpha-GPC)Nootropic supplement (choline precursor)

Verdict at Tovani Health

Fully compatible at typical OTC doses.

Alpha-GPC and ketamine have no clinically significant interaction. Same family as citicoline — a choline precursor that supports cholinergic neurotransmission and membrane synthesis. The 2021 Italian META-AGENT study suggested a possible increase in stroke risk with chronic high-dose alpha-GPC; that signal is preliminary and intrinsic to alpha-GPC rather than a KAP issue, but worth disclosing if you have cardiovascular history.

If you take Alpha-Glyceryl Phosphorylcholine 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 Alpha-Glyceryl Phosphorylcholine interacts with ketamine

Alpha-GPC is hydrolyzed to choline and glycerophosphate; the choline supports acetylcholine synthesis. No CYP interaction with ketamine.

What we do at intake

Disclose dose. Tell us about any cardiovascular history (the preliminary stroke-risk signal is small but worth knowing about).

Bottom line

Alpha-GPC and ketamine have no clinically significant interaction. Same family as citicoline — a choline precursor that supports cholinergic neurotransmission and membrane synthesis. The 2021 Italian META-AGENT study suggested a possible increase in stroke risk with chronic high-dose alpha-GPC; that signal is preliminary and intrinsic to alpha-GPC rather than a KAP issue, but worth disclosing if you have cardiovascular history.
