Natural Medications in Psychiatry


* Natural options cannot be patented and as result almost always have limited clinical trials due to lack of financial incentives to do more expensive, more rigorous studies. The following is a list of options that I and other psychiatrists have found helpful and have some clinical positive trials though too small and limited for official FDA approval. 


1.    S-Adenosyl Methionine (SAMe): Dose range usually 400 – 3200 mg/day. Fairly expensive. Cost $27 - $40/month for 800mg/day. 

Dosage Start 400 mg/day, raise by 200–400 mg every three to seven days to a target dose of 800–1600 mg daily; take on an empty stomach for better absorption

Side Effects: Nausea, vomiting, abdominal discomfort, diarrhea, constipation, dry mouth, sweating, dizziness, anxiety

Caution in patients with history of bipolar disorder, with cardiac arrythmia, or who are pregnant

Reliable brands: Doctor’s Best, Nature’s Trove, NOW, Swanson, Vitacost, and The Vitamin Depot

2.    L-Methylfolate: 7.5mg for a week then 7.5 – 15mg. Generally well tolerated

3.    Omega -3 Fatty Acid from fish oil (not flax seed): 

In brain Omega-3 fatty acids coat nerve cell membranes and provides neuroprotective and anti-inflammatory effects. They have also shown some efficacy as augmenting agent for bipolar depression. 

Side effects: Nausea, fishy taste, belching. Recommend enteric coated formulation or refrigerate the capsules. 

Reliable brands: Carlson Elite EPA Gems (1000/16.5 mg), GNC Triple Strength (734/266 mg), Nature Made 1400 (683/252mg), NutriGold Triple Strength (725/275 mg)

Dose usually 1,000mg a day (total EPA+DHA) for a month. If no benefit in 3 weeks, increase to 2,000mg for another 3 – 4 weeks. 
4.    5-HTP


1.    Chamomile 300 -700mg capsules 1 – 3 times a day. Suggest Natures Way brand

2.    Lavender extract tablets:  Recommend "Calm-Aid" made by Nature’s Way and take 1 - 2 a day. SE of lavender burping. Might try refrigerating if that happens. 

3.    Ashwagandha: Prefer "Cortisol Manager" made by Integrative Therapeutics. Take 1 at night.


4.    Rhodiola Rosea (see below) 


Sleep: Please also see Insomnia Guide on this website. 


1.    Melatonin: Dose 0.25 – 5mg. 

2.    Magnesium 

3.    Various natural concoctions that combines several ingredients like Theonine, Tryptophan, Valerian, chamomile, lavender, others... One suggestion is ZzzQuil Pure Zzzs. 



Rhodiola Rosea. Usually does not cause anxiety and less frequent crash at end of day. Recommend "Rosavin Plus" 1 pill in morning for few days and if no effect, try 2 pill in morning. Stop if get more anxious. 

Poor Memory:


American Gingseng (Panax quinquefolius) with 10% ginsenoside 500mg twice a day. Well tolerated but caution in patients with anticoagulants or undergoing surgery. 


Skin/Hair Pulling:

N-Acetylcysteine 600mg twice a day for couple of weeks. Then 1200mg twice a day for 2 more weeks and up to 1800mg twice a day. Data suggests taking for 2 months before deciding does not help.
