Children’s immune systems and nervous systems are closely connected, and when immune signaling is out of balance, mood, behavior and sleep can be affected too. I put this protocol together to share the nutritional products I commonly use to support immune balance, gut health and a calm nervous system in children alongside the care they receive from their medical team.

The mechanisms this protocol supports
The gut, the immune system and the brain talk to each other constantly, which researchers call the gut-brain axis. Immune signals released in response to infections can reach the brain and influence mood and behavior, a process sometimes described as neuroinflammation.
Glutathione is the body’s main antioxidant, and a balanced microbiome in the gut and throat supports healthy immune signaling.
Research has linked immune responses to infections with sudden-onset changes in mood and behavior in some children, which are sometimes described as PANS or PANDAS. Those changes always deserve a full medical evaluation, and this protocol is only meant to offer nutritional support as one part of a larger plan.
What is in the protocol
The exact products and directions are listed in the Fullscript plan, and here is what each one is commonly used to support.
- Biocidin LSF is a liposomal form of Biocidin, and because the manufacturer is discontinuing it, another Biocidin format may take its place once it is no longer available.
- G.I. Detox+ is a binder blend that is commonly used to support the gentle removal of unwanted compounds through the digestive tract.
- G.I. InnerCalm is a botanical formula that is commonly used to support a calm, comfortable digestive tract.
- Biocidin Throat Spray is commonly used to support a healthy microbial balance in the mouth and throat.
- NAC, or N-acetylcysteine, is a building block for glutathione and is commonly used to support antioxidant defenses.
- Ther-Biotic Kids from Klaire Labs is a probiotic formulated for children to support a balanced gut microbiome.
How to use it thoughtfully
- Please talk with your provider before starting, especially if you take medications, are pregnant or nursing, or have a health condition.
- This page does not list amounts, so follow the label or the specific guidance your provider gives you.
- When you can, add one product at a time so it is easier to notice how you feel.
- Sleep, nourishing food, daily movement and stress care are the foundation, and supplements are meant to build on them.
- Children need different amounts than adults, so please only use these products with guidance from your child’s provider.
Frequently asked questions

These products are commonly used with children, but amounts and suitability depend on the child, so please only use them with guidance from your child’s provider.
Why does gut health matter for a child’s mood?
The gut and brain communicate through the gut-brain axis, and research has linked gut and immune balance with changes in mood and behavior.
