Evidence-Based Protocol

Supplement stack ranked by research quality

Limited Evidence

Primary Stack (Tier 1)

Vitamin EC
400-1600 IU daily

Antioxidant; some evidence for preventing worsening of TD; less effective for established TD

12 studies | 600 participants
Vitamin B6C
100-400mg daily

Some studies show benefit for TD symptoms; may affect dopamine metabolism

6 studies | 200 participants

Supporting Stack (Tier 2)

Omega-3 Fatty AcidsC
2-4g EPA+DHA daily

Anti-inflammatory; supports neuronal membrane health; may help with psychiatric symptoms

5 studies | 150 participants
Branched-Chain Amino AcidsC
222mg/kg/day in divided doses

May reduce TD symptoms; compete with phenylalanine at blood-brain barrier

4 studies | 100 participants
MelatoninC
2-10mg at bedtime

Antioxidant; neuroprotective; may help with TD symptoms

4 studies | 100 participants

How It Works

Tardive dyskinesia (TD) is a movement disorder characterized by involuntary, repetitive movements, often of the face, tongue, and jaw. It typically develops as a side effect of long-term use of certain psychiatric medications, particularly older antipsychotics.

COMMON MOVEMENTS:

•Repetitive chewing or lip smacking
•Tongue protrusion or twisting
•Grimacing
•Rapid eye blinking
•Finger movements
•Rocking or thrusting of trunk

RISK FACTORS:

•Duration of antipsychotic use (main risk factor)
•Older age
•Female sex
•Diabetes
•Mood disorders
•First-generation (typical) antipsychotics > second-generation
•Higher doses

CRITICAL: TD requires medical management. This protocol is SUPPORTIVE ONLY.

MEDICAL TREATMENT:

•FDA-approved treatments: Valbenazine (Ingrezza) and deutetrabenazine (Austedo) - VMAT2 inhibitors; effective for TD
•Medication adjustment: If possible, reduce or switch to lower-risk antipsychotic
•Clozapine: Lowest TD risk if antipsychotic needed

PREVENTION:

•Use lowest effective dose of antipsychotics
•Regularly assess for TD (AIMS exam)
•Consider second-generation antipsychotics
•Limit duration of treatment when possible

* Vitamin E may help prevent worsening (less effective for established TD).

* Vitamin B6 has shown some benefit in small studies.

* Antioxidants may provide neuroprotective support.

Expected timeline: VMAT2 inhibitors show benefit within weeks. TD may be irreversible in some cases, especially if longstanding.
