The following supplements for trichotillomania are effective in the treatment of the disorder, according to medical studies: NAC, Vitamin D, Inositol, Milk Thistle and Melatonin.
On the video below, University of Minnesota Medical School researcher Jon Grant has discovered that a common anti-oxidant, widely available as a health food supplement, may help stop the urges of those with trichotillomania, characterized by compulsive hair-pulling.
What are some Supplements for Trichotillomania?
The following supplements for trichotillomania have scientific evidence for their effectiveness:
- NAC (N-acetylcysteine)
- Milk Thistle
NAC (N-Acetyl Cysteine)
The following studies were done in order to determine the efficacy and tolerability of N-acetylcysteine.
- Title: Repetitive Behaviors Treated With N-Acetylcysteine: Case Series.
- Number of Subjects: 1.
- Gender: female.
- Health Status: trichotillomania for the last 20 years.
- Age: 31.
This report describes a case series of a patient in whom trichotillomania was diagnosed at a center in Turkey.
We successfully treated the patient who suffer from previously mentioned disorders with NAC.
Outcome of our cases demonstrates the efficacy of NAC, which is effective and well tolerated on the treatment of obsessive-compulsive disorder-related disorders.
Can you use NAC for Trichotillomania?
- N-acetylcysteine (NAC) is a is a precursor to the aminoacid cysteine, a glutamate modulator. It may be effective in the pharmacological treatment of Body-Focused Repetitive Behaviors (BFRBs) such as Trichotillomania.
- Many studies suggest a NAC dose between 1200 to 2400 mg/day for 1-4 months as an effective treatment for Trichotillomania.
- Title: N-Acetylcysteine in the treatment of trichotillomania: remarkable results in two patients.
- Length: 10 weeks.
- Number of Subjects: 2.
- Gender: female.
- Health Status: trichotillomania.
- Age: 30 and 14.
The patients were prescribed with NAC (1200 mg/d).
Hair pulling behavior subsided within 2 months and 2 weeks of initiating NAC in the first and second patient, respectively. Complete hair regrowth was observed after 4 and 6 months of NAC treatment in the first and second patient, respectively. No side-effects related to NAC were noted.
NAC could be a well-tolerated and effective treatment option for trichotillomania.
- Title: N-acetylcysteine, a glutamate modulator, in the treatment of trichotillomania: a double-blind, placebo-controlled study.
- Length: 9 weeks.
- Number of Subjects: 50.
- Gender: 5 male, 45 female.
- Health Status: trichotillomania.
- Mean age: 34.3.
N-acetylcysteine (dosing range, 1200-2400 mg/d) or placebo was administered for 12 weeks.
Patients assigned to receive N-acetylcysteine had significantly greater reductions in hair-pulling symptoms. 56% of patients “much or very much improved” with N-acetylcysteine use compared with 16% taking placebo. Significant improvement was initially noted after 9 weeks of treatment.
This study, the first to our knowledge that examines the efficacy of a glutamatergic agent in the treatment of trichotillomania, found that N-acetylcysteine demonstrated statistically significant reductions in trichotillomania symptoms. No adverse events occurred in the N-acetylcysteine group, and N-acetylcysteine was well tolerated. Pharmacologic modulation of the glutamate system may prove to be useful in the control of a range of compulsive behaviors.
- Title: N-Acetylcysteine for the Treatment of Psychiatric Disorders: A Review of Current Evidence.
Oral N-acetylcysteine is safe and well tolerated without any considerable adverse effects. Current evidence supports its use as an adjunctive therapy clinically for psychiatric conditions, administered concomitantly with existing medications, with a recommended dosage between 2000 and 2400 mg/day.
We used a biobehavioral treatment consisting of melatonin and a standardized bed and wake time to decrease one girl’s head and mouth touches associated with sleep-related trichotillomania and trichophagia. We remotely coached the girl’s caregiver to implement all procedures and monitored response to treatment using a DropCam Pro video camera equipped with night-vision capabilities.
Head and mouth touches decreased, and her sleep pattern improved with the combination of treatment strategies.
We discuss our use of a novel mode of service delivery to treat sleep-related problem behavior.
Milk thistle has antioxidant properties and showed promise in trichotillomania in a prior case report. The goal of the current study was to determine the efficacy and tolerability of silymarin in children and adults with trichotillomania.
The study consisted of 6 weeks of milk thistle and 6 weeks of placebo with a 1-week wash-out in between. Dosing of milk thistle ranged from 150 mg twice a day to 300 mg twice a day.
There were no statistically significant treatment type-by-time interactions for the main outcome measure, but significant effects were seen for secondary measures (eg, time spent pulling per day for the past week). From baseline to week 6, there was a significant decrease in severity for the milk thistle group but not in the placebo group.
This trial failed to show that milk thistle was more effective than placebo on the main outcome measure, but milk thistle did demonstrate significant improvements on select secondary outcome measures. These findings may shed light on important neurochemical targets worthy of future investigation.
A cause for Trichotillomania: Vitamin deficiency?
The following study found a possible trigger for trichotillomania: vitamin deficiency, specifically Vitamin D. It can be naturally obtained with regular sunlight exposure, or with a balanced diet that contains foods such as fish, red meat and egg yolks.
However, if you are lacking in any of those, you can take between 1,000–4,000 IU (25–100 mcg) of Vitamin D in supplement form to reach healthy levels.
Vitamin D deficiency is thought to be linked to rickets in children and to a range of different diseases in adults, including osteoporosis, osteomalacia, cardiovascular diseases, cancer, dermatological diseases, and psychiatric disorders. We report a case of a 4-year-old girl with trichotillomania triggered by vitamin D deficiency resolving dramatically with vitamin D therapy.
What Vitamins to take for Trichotillomania?
In conclusion, Vitamin D is one of the most important vitamins for trichotillomania treatment and prevention.
