Many people ask, “What supplements should I be taking?” While there isn’t a single supplement that works for everyone, certain vitamins and nutrients can support your brain, improve mood, increase energy, and promote overall wellness when combined with a healthy lifestyle.
At Psychiatry Unplugged, we believe supplements should complement—not replace—evidence-based mental health treatment. If you’re experiencing anxiety, depression, ADHD, bipolar disorder, or chronic stress, it’s important to work with a qualified mental health provider before starting any supplement regimen.
Can Supplements Improve Mental Health?
The answer is: sometimes.
Research shows that nutritional deficiencies can contribute to symptoms of depression, anxiety, fatigue, brain fog, and poor concentration. Correcting these deficiencies may improve symptoms, especially when paired with therapy, medication (when appropriate), exercise, quality sleep, and stress management.
Remember that supplements are not regulated as strictly as prescription medications, so quality matters.
1. Omega-3 Fish Oil
Omega-3 fish oil is one of the most studied supplements for mental health.
Potential Benefits
- Supports brain function
- May reduce symptoms of depression
- Helps decrease inflammation
- Supports heart health
Look for a product containing a higher amount of EPA than DHA, as EPA appears to have the strongest evidence for mood support.
2. Vitamin D
Vitamin D deficiency is extremely common, especially in people who spend most of their time indoors.
Low vitamin D levels have been associated with:
- Depression
- Low energy
- Fatigue
- Seasonal mood changes
Ask your primary care provider to check your vitamin D level before taking high doses.
3. Magnesium
Magnesium plays a role in over 300 biochemical reactions in the body.
It may help with:
- Anxiety
- Muscle tension
- Sleep quality
- Stress response
- Headaches
Many people prefer magnesium glycinate because it is generally well tolerated and less likely to cause stomach upset.
4. B-Complex Vitamins
B vitamins help your brain produce important neurotransmitters, including serotonin and dopamine.
They may support:
- Energy
- Memory
- Focus
- Mood
Vitamin B12 deficiency can sometimes mimic symptoms of depression or cognitive decline.
5. Iron (Only if You’re Deficient)
Low iron can contribute to:
- Fatigue
- Brain fog
- Difficulty concentrating
- Low motivation
Iron should only be taken after confirming a deficiency through blood work, as too much iron can be harmful.
6. Zinc
Zinc is involved in immune health and brain function.
Some studies suggest it may play a supportive role in treating depression when combined with traditional treatment.
7. Probiotics
Your gut and brain communicate through what scientists call the gut-brain axis.
A healthy gut microbiome may help support:
- Mood
- Stress management
- Immune function
- Digestion
Research is still evolving, but probiotics may be beneficial for some individuals.
8. L-Theanine
Found naturally in green tea, L-theanine may promote:
- Relaxation
- Improved focus
- Reduced stress
- Calm without significant drowsiness
Some people use it to reduce anxiety during the day.
9. Creatine
While many people associate creatine with weightlifting, emerging research suggests it may also support:
- Brain energy production
- Memory
- Cognitive performance
- Depression treatment when used alongside prescribed care
More research is ongoing, but results are promising.
10. Prenatal Vitamins (When Planning Pregnancy)
If you’re trying to conceive, taking a prenatal vitamin before pregnancy can support both maternal health and fetal development.
Look for one containing:
- Folate
- Iron
- Iodine
- Vitamin D
- DHA, if included
Discuss your plans with your healthcare provider before becoming pregnant, especially if you’re taking psychiatric medications.
Supplements That May Interact With Psychiatric Medications
Natural does not always mean safe.
Certain supplements can interact with antidepressants, mood stabilizers, stimulants, or anti-anxiety medications.
Examples include:
- St. John’s Wort
- SAM-e
- 5-HTP
- High-dose melatonin
- Kava
- Valerian root
Always tell your psychiatrist about every supplement you’re taking.
Lifestyle Still Matters Most
Even the best supplements cannot replace healthy habits.
To support both your mental and physical health:
- Eat a balanced diet rich in fruits, vegetables, lean protein, and healthy fats.
- Exercise regularly.
- Sleep 7–9 hours each night.
- Manage stress with mindfulness, therapy, or relaxation techniques.
- Stay hydrated.
- Limit alcohol and recreational drug use.
- Maintain regular medical checkups.
When Should You See a Psychiatrist?
If you’re struggling with persistent symptoms such as:
- Anxiety
- Depression
- ADHD
- Mood swings
- Panic attacks
- Poor concentration
- Difficulty sleeping
- Loss of motivation
Supplements alone may not be enough.
Mental health conditions are medical conditions, and effective treatment often includes a personalized combination of therapy, lifestyle changes, medication (when appropriate), and nutritional support.

Frequently Asked Questions

Vitamin D, vitamin B12, folate, and iron deficiencies have all been linked to depressive symptoms in some individuals.
Should everyone take magnesium?
Not necessarily. While many adults do not meet recommended magnesium intake, it’s best to discuss supplementation with your healthcare provider, especially if you have kidney disease or take medications that may interact.
How long do supplements take to work?
Depending on the supplement and the underlying deficiency, it may take several weeks to a few months before noticeable benefits occur.
