Australian winters are consistent in one particular way: the cold and flu season arrives reliably between June and September, cycling through households, workplaces and classrooms. Alongside good hygiene and adequate rest, targeted nutritional support is something many people ask our Naturopaths and Homeopaths about each year.
This guide covers the key nutrients and herbal medicines our practitioners commonly consider when supporting clients through the cold and flu season, what the research suggests, and how to think about putting together a winter supplement protocol that actually makes sense for your body.

What our Naturopaths look at before recommending supplements
Naturopathic immune support is not about reaching for a single product and hoping for the best. Our practitioners take a whole-body view, looking at sleep quality, stress load, gut health and nutritional status before recommending any supplement protocol. In many cases, the most impactful immune support has nothing to do with a capsule.
That said, certain nutrients and botanicals have been explored in the research context of immune function and upper respiratory health, and our practitioners consider these as part of a broader picture.
Key nutrients for cold and flu season
Vitamin C
Vitamin C is one of the most extensively studied nutrients in the context of immune function. It plays a role in several aspects of immune cell activity and its requirements may increase during periods of acute illness or high stress. Our practitioners often consider vitamin C at higher therapeutic doses during an acute illness, and at maintenance doses through the winter months as part of general immune support.
Zinc
Zinc is involved in the development and activity of immune cells, and deficiency is associated with reduced resistance to infection. Some research has looked at zinc lozenges specifically in the context of cold symptom duration, with early administration appearing most relevant. Form matters: zinc acetate and zinc gluconate are the forms that appear most frequently in research. Our practitioners assess zinc status as part of an initial consultation.
Vitamin D
Vitamin D deficiency is widespread across Australia, and levels often drop through the autumn and winter months when sun exposure decreases. There is a meaningful relationship between vitamin D status and immune function, and our practitioners routinely check vitamin D through pathology and recommend supplementation where deficiency is identified.

Herbal medicine for winter immune support
Herbal medicine has a long history of use in immune support and remains a central part of naturopathic practice. Our practitioners formulate customised herbal tonics based on your individual presentation, drawing on botanicals including:
- Echinacea species, used in Western herbal medicine for respiratory health and studied for their potential role in immune function
- Andrographis, a herb used in both Ayurvedic and traditional Chinese medicine that has attracted clinical research interest for upper respiratory conditions
- Astragalus, used traditionally for immune resilience and increasingly incorporated into integrative practice
- Elderberry (Sambucus nigra), which has attracted growing research interest for its potential role in upper respiratory health, with some studies exploring its use in the context of cold and flu symptom severity
- Medicinal mushrooms including reishi, turkey tail and shiitake, which contain bioactive compounds explored in immune research
Each herbal tonic is formulated individually and posted to you after your consultation with detailed instructions.

Supporting children through cold and flu season
Children spend a great deal of time in group settings during winter, and parents frequently ask us what can help support their children's resilience through the season. Paediatric immune support follows the same whole-body principles as adult care, and our practitioners offer children's health consultations for families wanting personalised, age-appropriate advice.
We always recommend consulting with a qualified health practitioner before beginning any supplement protocol for children. Our Naturopaths and Homeopaths who specialise in paediatric health can help you work out what is appropriate for your child's specific circumstances.
Gut health and immune function
It is worth noting that a significant proportion of immune activity is associated with the gut. Clients who present with frequent infections or slow recovery often have underlying gut health concerns that have not yet been addressed. Our practitioners take gut health into account as part of every immune support protocol, and in many cases it is where meaningful improvement begins.
Building your winter supplement protocol
Rather than picking up a generic immune formula off the shelf, our practitioners can work with you to build a targeted winter supplement protocol based on your health history, current nutritional status, and individual risk factors. This is especially valuable if you have a history of getting sick frequently, recover more slowly than you would like, or are managing another health condition that may affect your immune system.
Our clinic is based in Liverpool, Sydney, and we offer online consultations across Australia. A discovery call is the easiest and most cost-effective place to start.
