Signs of Anxiety in Teens

“When we support the nervous system, we support the whole child.” — Dr. Mona Delahooke

Best Supplements for Teenage Anxiety

Here are the top science-backed natural supplements I recommend in my clinical practice:

1. Magnesium

Magnesium helps regulate the nervous system by activating GABA receptors, reducing muscle tension, and promoting better sleep. Teens with anxiety often burn through magnesium quickly, especially if they’re in a chronic stress state.

Found in:

• • • Spinach
    • pumpkin seeds
    • Almonds
    • black beans
    • dark chocolate

One of the most widely trusted forms of magnesium is Magnesium L-Threonate – a unique form that crosses the blood-brain barrier and supports brain function more directly.

• • • Helps ease nervousness, restlessness, and chronic worry
    • Supports memory, cognition, and focus
    • Can be taken in powder or capsule form

Tip: Look for chelated forms like glycinate or threonate for better absorption

2. L-Theanine

This amino acid helps take the edge off without causing drowsiness—perfect for anxious teens who still need to focus.

L-Theanine, naturally found in green tea, promotes alpha brainwaves (linked to calm focus) and increases dopamine and serotonin levels. It’s one of the gentlest, most effective supplements for easing racing thoughts and test anxiety.

• • • Helps with social anxiety and overthinking
    • Pairs well with magnesium or GABA
    • Great as-needed before stressful events (e.g., school presentations)

3. Omega-3 Fatty Acids (EPA & DHA)

If your teen is moody, overwhelmed, or emotionally reactive, omega-3s can help stabilize and soothe their brain.

These essential fats support healthy brain development, improve communication between neurons, and lower inflammation—a factor increasingly linked to anxiety and depression. Studies show that low levels of Omega-3s are associated with greater emotional dysregulation.

• • • Look for high EPA formulas (at least 1000 mg/day) for anxiety (Reily et al., 2023)
    • Can improve mood, attention, and cognitive function
    • Found in fish oil or algae-based supplements for vegans

Tip: Start low to avoid digestive upset and take with meals

Found in:

• • • Fatty fish like salmon
    • Sardines
    • Mackerel
    • Trout

4. GABA

If your child goes from 0 to 100 emotionally, GABA can help the brain slow down and feel safer.

GABA is the brain’s natural calming chemical. While there’s debate about whether oral GABA crosses the blood-brain barrier, many parents report it helps with quick relief during anxious moments—especially when combined with L-Theanine.

• • • Use for situational anxiety (e.g., travel, sleepovers, public speaking)
    • Can be taken as a capsule, chewable, or lozenge
    • Often works within 30–60 minutes

Found in:

• • • Kimchi
    • Miso
    • Yogurt (though not in high enough amounts to replace supplementation)
    • Other fermented foods

5. Rhodiola Rosea

This adaptogen helps the brain and body bounce back from stress—especially for teens who feel emotionally drained or mentally foggy.

Rhodiola supports the HPA axis, which controls our stress response, and is known to reduce fatigue and increase mental resilience. It can be especially helpful for teens who struggle with low energy, motivation, or burnout-related anxiety.

• • • Best taken earlier in the day to avoid sleep disruption
    • Works well for performance anxiety and executive dysfunction
    • Start with a low dose and build gradually

6. B-Complex Vitamins

B vitamins fuel the brain—especially when it’s under stress. If your teen is mentally exhausted or emotionally “flat,” they may need more of these.

Vitamins B6, B9 (folate), and B12 are critical for neurotransmitter production (like serotonin and dopamine). Teens with methylation issues or high stress may burn through these faster than they can replace them.

• • • Helps with mood, focus, and nervous system function
    • Choose methylated forms (like methylfolate or methylcobalamin)
    • Avoid sugary gummies with low-dose blends—opt for quality brands

Found in:

• • • B6: Tuna, chicken, bananas, chickpeas
    • B9 (Folate): Leafy greens, lentils, asparagus
    • B12: Meat, dairy, eggs, and fortified cereals

Herbal Supplements That Help with Teen Anxiety

Yes, certain herbal remedies have been shown to support emotional regulation and reduce anxiety symptoms—especially when stress is high or sleep is off track. These can be great add-ons when you're looking for gentle, plant-based support.Just remember: herbs are powerful and should be chosen with care. Always talk to your provider before starting an herbal remedy—especially if your child is taking medications or has other health conditions.

1. Passionflower

Known for its gentle calming effects, especially around bedtime.

Passionflower is a natural herb that can help with restlessness, racing thoughts, and sleep trouble. It works by increasing levels of GABA in the brain, which supports a more relaxed state.

It’s particularly helpful for teens who feel "on edge" all day and can’t settle down at night.

• • • Great for sleep-related anxiety
    • Can be taken as a tea, capsule, or liquid extractOften paired with other calming herbs like Lemon Balm or Chamomile

2. Valerian Root

One of the stronger herbal remedies for sleep and stress.

Valerian is often called “nature’s Valium” because it has a sedative-like effect on the nervous system. For teens who are highly anxious, wired at bedtime, or can’t fall asleep, Valerian can be a helpful short-term option.

• • • Best used before bed to improve deep sleep and mental clarity
    • Not recommended for kids under 7
    • May take 2–3 weeks for full effect

A study combining Valerian and Lemon Balm recorded significant improvements in anxiety-related behaviors, sleep quality, and focus (Müller and Klement, 2006)

3. Ashwagandha (Withania somnifera)

An adaptogenic herb that helps regulate the body’s response to chronic stress.

Ashwagandha is a powerful nervous system stabilizer often used to reduce cortisol levels (the body’s main stress hormone). It’s particularly helpful for teens experiencing burnout, panic, or emotional exhaustion.

• • • Shown to reduce anxiety, improve sleep, and enhance resilience (NIH, n.d.)
    • Works well for teens under academic pressure or emotional strain
    • Typically taken in capsule or powder form
    • May take 2–4 weeks for full benefits

Caution: Ashwagandha is not recommended for teens with hyperthyroidism or certain autoimmune conditions—always consult a provider.

Every brain is different. What works for one child might not work for another.Tips for choosing:

• Consider your teen’s symptom pattern (e.g., sleep vs focus vs irritability)
• Work with a professional who understands brain-based interventions
• Combine with tools like QEEG brain mapping to see what areas are dysregulated

What Mistakes Should I Avoid When Using These Supplements?

• Skipping proper dosage or consistency
• Choosing cheap, untested brands

What’s the best supplement for teen anxiety?

There’s no one-size-fits-all, but Magnesium L-Threonate, L-Theanine, and Omega-3s are a great place to start. Always match the supplement to your child’s symptoms.

Can I give my teen multiple supplements at once?

Yes, but start one at a time and monitor how they respond. Combining calming (e.g., Magnesium) with mood support (e.g., Omega-3s) can be helpful.

Some supplements (like GABA) work quickly, while others (like Omega-3s) may take 4–6 weeks. Consistency is key.
