Research Preview — Unreviewed AI Research

AI-assisted Research Preview - not yet human-reviewed and not part of Published Knowledge.

This is automated research that has not yet been reviewed by a person. It is not MyDeficiencies published knowledge, it is not medical advice, and it may be incomplete or wrong. It has been added to our editorial review queue.

Gabapentinoid, anticonvulsant / alpha-2-delta calcium channel ligand. Recognized as Gabapentin.

Researched 9/3/2026 · Adversarial review ran: 4 confirmed, 4 scope corrections, 2 rejected.

1 of 1 cited sources were confirmed to exist as described. That check confirms the source is real, not that it supports the claim.

Interactions and timing

How this medication and a nutrient affect each other's absorption, handling or timing. This is not depletion.

Medication and nutrient interaction

Magnesium (as magnesium oxide antacid)

exact entity

Interaction and timing

An interaction between Gabapentin and Magnesium (as magnesium oxide antacid) was reported, affecting absorption, handling or timing. No change in nutrient status is claimed here. This is an interaction between Gabapentin and Magnesium (as magnesium oxide antacid), not a measured change in your Magnesium (as magnesium oxide antacid) status.

1 cited source and detail

What was measured: An interaction between Gabapentin and Magnesium (as magnesium oxide antacid) was reported, affecting absorption, handling or timing. No change in nutrient status is claimed here.

Proposed mechanism: Proposed reduced intestinal absorption of gabapentin due to interaction with magnesium in the gut, potentially involving the saturable amino acid transporter used for gabapentin absorption. A mechanism explains how an effect could occur. It is not itself a measured clinical outcome.

1 of 1 cited sources were checked and found to support this specific claim. A source existing is not the same as a source supporting the claim.

Why it is here: This is an absorption, binding or timing interaction between the medication and the nutrient, not a measured depletion.

Searched, no supporting evidence found

These relationships were searched for in this research run and no supporting evidence was found. Absence of evidence is not evidence of absence.

Zinc

unresolved scope

Searched, no supporting evidence found

No gabapentin-specific human study measuring zinc levels was found in this research run.

What was searched

We looked for this relationship and did not find supporting evidence. Absence of evidence is not evidence of absence.

Why it is here: No retrievable source was found for this relationship.

Copper

unresolved scope

Searched, no supporting evidence found

No gabapentin-specific human study measuring copper levels was found in this research run; a case report on a patient using multiple drugs including gabapentin is not attributable to gabapentin alone.

What was searched

We looked for this relationship and did not find supporting evidence. Absence of evidence is not evidence of absence.

Zinc/copper balance

unresolved scope

Searched, no supporting evidence found

Calcium

unresolved scope

Searched, no supporting evidence found

No human study measuring serum calcium as an outcome of gabapentin therapy was found in this research run.

Why it is here: No retrievable source was found for this relationship.

Mitochondrial-related biological context

unresolved scope

Searched, no supporting evidence found

No human study measuring a specific mitochondrial nutrient or cofactor change with gabapentin was found in this research run.

What was searched

We looked for this relationship and did not find supporting evidence. Absence of evidence is not evidence of absence.

Why it is here: No retrievable source was found for this relationship.

Vitamin B12 / folate / biotin depletion

unresolved scope

Searched, no supporting evidence found

No reliable primary evidence was found that gabapentin specifically depletes B12, folate, or biotin. The one retrieved human study on AED-related B-vitamin status explicitly excluded gabapentin from its studied cohort. The search also surfaced numerous commercial wellness-blog claims asserting this relationship without verifiable primary citations; those were rejected as non-qualifying sources.

What was searched

We looked for this relationship and did not find supporting evidence. Absence of evidence is not evidence of absence.

Why it is here: Searched in this research run (WebSearch (general literature); Epilepsy & Behavior article (Mintzer et al. 2012) retrieved via Jefferson Digital Commons open-access repository); no qualifying Gabapentin-specific evidence was identified.

Evidence limitations

What this cannot tell you

  • This is automated research that has not yet been reviewed by a person. It is not MyDeficiencies published knowledge, it is not medical advice, and it may be incomplete or wrong. It has been added to our editorial review queue.
  • This batch found no exact-medication human evidence establishing that gabapentin changes zinc, copper, zinc/copper ratio or vitamin A status.
  • Much of the circulating popular claim content conflates gabapentin with other anticonvulsants (phenytoin, phenobarbital, valproic acid) studied mainly in pediatric epilepsy populations.
All research limitations for this run
  • Case report evidence is anecdotal, involves polypharmacy, and cannot establish causation for gabapentin specifically.
  • Absence of evidence is not evidence of absence; this reflects the current retrievable literature only.
  • Much retrievable evidence for this medication is class-wide (anticonvulsants generally) rather than gabapentin-specific, and this packet has attempted to keep those distinct.
  • Secondary consumer health sources were used only for claim discovery and were traced to primary sources where possible; several popular claims could not be substantiated and were rejected.
  • Sample sizes in the directly relevant pharmacokinetic and pyridoxine studies are small.
  • This packet covers only Vitamin B12, Calcium, Biotin, and Mitochondrial-related biological context per batch 3 of 3 scope restriction.
  • No exact-medication randomized controlled human trials were found measuring vitamin B12 or biotin status with gabapentin.
  • Calcium and bone findings rely heavily on animal and mechanistic data with internal contradictions.
  • Mitochondrial context is supported only by in vitro enzyme assays, high-concentration cell culture work, and a narrative review, not direct human biomarker studies.
  • 20 of 27 cited sources could not be confirmed to exist as described. Claims resting only on those sources are withheld.
  • Provider output was capped/truncated multiple times during drafting; some structured content was reconstructed in a separate serialization-only turn.
  • Several cited sources are unreachable or absent per existence check and cannot be treated as verified evidence.
  • Most positive-leaning items rely on animal, in vitro, or class-level (multi-drug cohort) evidence rather than exact-medication human data.
  • Negative findings reflect only the searches actually run and do not establish that no relationship exists.
  • 8 of 11 sources that were confirmed to exist were not confirmed to support the specific claim they were attached to. Existence is not support, and those claims are withheld.
  • Every critical error the review reported was traced to a specific item and that item was withheld. Unrelated findings that independently pass every check were not suppressed by it.
  • No direct human evidence measuring a nutrient endpoint in people taking Gabapentin was found in this run. That is a statement about what we found, not a statement that no effect exists.
  • Search was not exhaustive; absence of evidence is not proof of no relationship.
  • Search reflects public/web-search discoverable literature, not a full institutional database (e.g. Embase, Micromedex) search; absence of evidence is not proof of no relationship.
  • One taurine-transporter paper (PMID 26631583) could not be retrieved to confirm whether gabapentin was among the tested compounds. Other potential nutrient dimensions remain unresearched.

  • Existence of a source and support for a claim are checked separately. A confirmed identifier means the record is real, not that it supports the statement it is cited for.

Questions for your clinician

These are conversation prompts, not findings about you.

  • Could Gabapentin affect any nutrients over time in my situation?
  • Are there symptoms or risk factors that would make further evaluation appropriate?
  • Could diet, other medications, or health conditions affect this relationship?
  • Would laboratory testing be clinically appropriate for me?
  • Are there medication or supplement interactions I should understand?
