Healing HPA Axis Dysfunction
Adaptogens + Nutrients for Cortisol and Stress Balance
When your child is living in a near-constant state of fight-or-flight, anxious, agitated, exhausted, or struggling to sleep, it’s worth taking a closer look at their HPA axis. Healing the HPA axis can provide much needed stability.
The HPA axis (short for hypothalamic-pituitary-adrenal axis) is the body’s central stress-response system. It regulates cortisol levels, sleep-wake cycles, energy production, and even inflammation. When it’s dysregulated, everything from mood swings to blood sugar crashes to hormone imbalances can show up.
And in children with PANS/PANDAS, chronic infections, mold exposure, or trauma, the HPA axis is almost always impacted, often swinging between burnout and hyperarousal.
Many families and practitioners turn to adaptogens, blood sugar support, and calming nutrients to help the body shift out of survival mode and toward regulation.

Adaptogens for Cortisol & Adrenal Balance
Adaptogens are herbs that help the body adapt to stress, whether cortisol is too high or too low. They support resilience, restore balance to the HPA axis, and promote more consistent energy and emotional regulation over time.
Ashwagandha
Ashwagandha is a foundational adaptogen for regulating cortisol and restoring HPA axis balance. Unlike energizing adaptogens, Ashwagandha is deeply calming, making it a good match for children who are anxious, exhausted, or swinging between emotional highs and lows. It gently steadies cortisol levels over time, supporting both emotional regulation and more consistent energy throughout the day. Ashwagandha also has anti-inflammatory properties, so it can pull double-duty in the daily herbal supports. It’s best used consistently over time because it builds slowly, parents may not see full effects for several weeks to a few months. Start low, and increase gradually toward a full dose.
Rhodiola
Rhodiola is a stimulating adaptogen that supports focus, stamina, and mental clarity under stress. It’s particularly useful for kids who seem foggy, unmotivated, or easily overwhelmed by mental tasks, often what you see in post-viral fatigue, chronic Lyme, or cortisol crash patterns. It also has mild antidepressant-like effects by influencing serotonin and dopamine pathways, which can support mood in children who seem emotionally flat or unmotivated. Because it can be stimulating, Rhodiola is best used in the morning or early afternoon, and may not be appropriate for kids who are already wired or hyperaroused. I use Rhodiola daily to support my energy levels and stress response for challenging seasons. As a PANS/PANDAS parent, it’s one of the herbs I cannot live without!
Holy Basil
Holy Basil, known as Tulsi in Ayurvedic medicine, is one of the gentlest adaptogens, and one of the most effective for families living in chronic stress. It has a unique ability to lower cortisol while promoting mental clarity, making it a go-to for emotional regulation and anxious restlessness. Unlike more stimulating adaptogens, Holy Basil has a balancing effect: it can ease agitation without sedating, while also offering mild antidepressant properties. For kids with PANS/PANDAS who are emotionally reactive or in a constant state of tension, Holy Basil helps take the edge off. It’s also an antimicrobial and antioxidant, adding an immune-supportive element. It pairs well with Gotu Kola or Ashwagandha as part of a gentle stress and mood protocol.
Blood Sugar & Mood | No One Wins When They're Hangry
Maintaining stable blood sugar is essential for hormone balance, especially in kids prone to mood swings, meltdowns, or midday crashes. When blood sugar spikes and drops, it can trigger irritability, anxiety, fatigue, and full-on emotional chaos (ask me how I know). Supporting balanced glucose levels with herbs and nutrients helps keep energy steady, moods more even, and makes for far fewer “hangry” episodes. A nourished brain is a calmer brain.
Berberine
Berberine is a plant compound found in herbs like Goldenseal, Oregon Grape, and Barberry. It can stabilize blood sugar by improving insulin sensitivity and reducing glucose spikes. But it also has powerful antimicrobial and anti-inflammatory effects—making it a dual-purpose tool for kids managing both chronic infections and mood dysregulation. Blood sugar swings can look like sudden meltdowns, irritability, anxiety, or mid-morning fatigue in kids. Berberine helps smooth those out by supporting more balanced glucose release and preventing the cortisol spikes that often follow sugar crashes. Start low and go slow with Berberine, especially in sensitive kids. It’s best taken with meals (to avoid the next crash), and may be rotated in and out of a protocol depending on gut tolerance and symptom patterns.
Konjac Root (Glucomannan)
Konjac root is a soluble fiber that works by forming a gentle, gel-like substance in the digestive tract. It works mechanically, not hormonally. This slows down the absorption of sugars and carbohydrates, resulting in more stable blood sugar levels after meals. For kids with glucose-sensitive mood shifts or late-day energy crashes, konjac can be especially helpful.
It also has a prebiotic effect, feeding beneficial gut bacteria, and supports regular bowel movements without being harsh. By blunting blood sugar spikes, konjac can also reduce cortisol surges and calm the nervous system over time. It’s also helpful for detox, binding to bile acids and toxins in the gut.
Start with very small doses and increase gradually with plenty of water. Take 10-20 minutes before meals. It expands significantly, so hydration is key.
Caution: Because of its fiber content, do not give konjac root dry (don’t open capsules into food unless mixing thoroughly with water), and avoid giving it right before bed. Always monitor how your child responds and adjust slowly.
Glycine
Glycine is a calming amino acid that does double duty: it helps support blood sugar regulation and soothe the nervous system. It may improve insulin sensitivity, helping buffer post-meal glucose spikes, and supports stable energy.
It’s also an inhibitory neurotransmitter in the brain, similar to GABA. It promotes relaxation without sedation and supports sleep quality, emotional regulation, and detoxification, particularly by fueling glutathione production.
For sensitive or neurologically inflamed kids, glycine can be a gentle way to support both metabolic balance and emotional calm. It has a sweet taste so it’s often tolerated even by picky eaters when mixed into juice or applesauce.
Dietary Considerations
Adaptogens and herbs can only go so far if meals are blood sugar bombs. For children with HPA axis dysfunction or PANS/PANDAS, breakfast is especially important to restoring the HPA axis. Protein + fat in the morning helps set the tone for stable blood sugar all day. Skipping breakfast or relying on carbs alone can worsen cortisol imbalances and emotional volatility. Aim for small, frequent meals that contain protein, healthy fats, and fiber. Avoid high-sugar or ultra-processed foods that spike insulin and then crash energy levels. These dietary shifts are simple, but lay the foundation for herbs to work more effectively to support the HPA axis.
Sleep and Melatonin Support for Hormonal Health
Supporting melatonin and calming the nervous system improves not just sleep, but immune and hormone function, too.
Melatonin
Start with 1mg for kids (more is not better)
Some research suggests that higher doses of melatonin over long periods may impact hormone development. Many practitioners recommend staying below 3mg in children unless directed by a healthcare provider.
Passionflower
Gentle nervine and mild sedative
Eases nighttime anxiety and racing thoughts
Can be combined with Skullcap or Chamomile
Chamomile
Classic bedtime herb for calming the nervous system
Also soothes digestion
Liver and Detoxification Support for Hormone Health
The liver helps break down excess hormones and detox environmental chemicals, both of which affect the HPA axis. Supporting gentle liver function helps reduce hormone overload and inflammatory stress.
- Milk Thistle: Milk Thistle supports liver health, helping the body clear out toxins and excess hormones.
- Dandelion Root: Dandelion root promotes bile flow, supporting hormone metabolism and is a gentle detoxifier that supports energy and digestion.
- NAC: NAC boosts glutathione production, which is essential for liver detoxification. It supports liver function and helps manage oxidative stress that can disrupt hormone balance.
For more about supporting detoxification pathways see Detox Pathways.
Nervous System Calming and Emotional Support
Cortisol doesn’t operate in isolation, it’s regulated by the nervous system. Calming sympathetic overdrive is a critical piece of HPA axis recovery.
GABA
GABA is the body’s primary inhibitory neurotransmitter—its job is to pump the brakes on an overstimulated nervous system. When your child is locked in fight-or-flight mode, struggling with rage episodes, anxiety, or hyperactivity, GABA may help restore a sense of internal calm. Think of it as a “chill signal” for the brain. For kids with PANS/PANDAS, MCAS, or HPA axis dysfunction, low GABA can make the world feel overwhelming and hard to regulate emotionally. Supplementing with GABA has been used to support mood, stress, and sleep.
Best used: in the evening or during periods of high agitation.
If your child has paradoxical reactions (more hyper, not calmer), try a much smaller dose or consider GABA precursors like L-theanine or taurine instead.
L-Theanine
L-Theanine, an amino acid found naturally in green tea, has a remarkable ability to promote relaxation without sedation. It works by boosting alpha brain waves, those associated with calm focus and a meditative state. For kids who struggle with anxious restlessness, scattered thinking, or emotional rigidity, L-Theanine may help smooth out jagged edges without making them sleepy. It also helps balance levels of neurotransmitters like dopamine and serotonin, giving it subtle mood-stabilizing effects that can be felt both immediately and cumulatively. Unlike GABA, which directly acts on GABA receptors, L-Theanine nudges the system toward calm by encouraging the body to make more of its own inhibitory neurotransmitters. This makes it a good option for sensitive kids or those who don’t tolerate GABA well.
Best used: in the morning or afternoon to reduce anxious energy and support focus.
For kids with school anxiety, OCD loops, or test-day jitters, L-theanine or green tea can be given before school to set the stage for a calmer day. Something we all need! To read more about calming the nervous system, head to the Herbal Guide to Nervous System Support.
Wrapping Up | Healing the HPA Axis Takes Time—But It’s Possible
Healing the HPA axis isn’t about chasing the perfect supplement. It’s about giving your child’s body the tools, space, and support it needs to shift out of survival mode. The herbs and nutrients listed here can help regulate cortisol, stabilize mood and energy, and rebuild resilience, but they work best when paired with consistent nourishment, rest, and emotional safety.
Every child’s stress response system has a history. And in kids with PANS/PANDAS, that system has likely been under pressure for a long time. Healing takes time. But with the right support, it happens.
