Quick Summary: Winter doesn’t weaken your immune system, but it does place extra demands on it. Recognising early signs that your body is under pressure, and responding with consistent nutrition and simple routine support, can help you stay balanced through the colder months.
Why Winter Changes How Your Body Responds
There’s a common assumption that cold weather weakens immunity. In reality, winter changes the conditions your immune system operates in.
Reduced daylight, drier indoor air, and more time spent indoors can all increase the number of seasonal challenges your body has to deal with. At the same time, sleep patterns, activity levels, and food choices often shift without you noticing.
None of this directly damages your immune system. Instead, it increases how often your body needs to respond, while reducing some of the environmental support it normally relies on.

Seven Signs Your Immune System May Be Under Pressure
Your body often signals immune strain quietly, long before anything obvious develops. These signs become relevant when they form patterns rather than appearing occasionally.
1. The “Almost Ill” Feeling That Lingers
A scratchy throat, slight heaviness, or the sense you’re fighting something off that doesn’t fully shift. This can reflect repeated low-level challenges without enough recovery time.
2. Slower Recovery Than You’re Used To
Minor illnesses or everyday cuts taking noticeably longer to resolve than normal can indicate that your system is working harder than usual.
3. Catching Everything That Goes Around
If you consistently pick up seasonal bugs while others don’t, your immune responses may not be as efficient as they could be.
4. Ongoing Tiredness Despite Rest
This isn’t about poor sleep. It’s a persistent fatigue that doesn’t lift even when you’re resting well, often linked to the energy demands of immune response.
5. Skin Changes or Delayed Healing
Persistent dryness, breakouts, or slower healing can reflect how your body is prioritising repair and defence.
6. Digestive Changes
Bloating, irregularity, or reacting to foods you normally tolerate can signal that the digestive system can be under extra strain.
7. Recurring Minor Issues
Cold sores or other small issues appearing more frequently than usual can suggest your body is dealing with increased demand overall.
Important: Occasional immune stress is normal, especially in winter. If symptoms persist, worsen, or require repeated medical treatment, speak with your GP.
Nutrients Commonly Used to Support Immune Function
Not every nutrient marketed for immune health has meaningful evidence behind it. Some, however, are consistently recognised for their role in normal immune function.
We explain the sourcing and purpose behind the nutrients we use in more detail on our ingredients overview page.
- Vitamin C – commonly used to support everyday immune defence and routine resilience
- Plant compounds – found in a wide range of foods and extracts, often used to support the body during periods of increased seasonal demand
- Foundational nutrition – a consistent diet and healthy lifestyle remain the base layer for normal immune function
What matters most is consistency. Moderate, routine intake tends to support day-to-day function more effectively than irregular high doses.

Does Supplement Format Make a Difference?
Once people decide to supplement, format becomes the next question. Tablets, powders, and liquids all work differently in practice.
If you’d like a deeper explanation, we cover this in more detail in our guide to how absorption and delivery formats affect routine consistency.
- Tablets and capsules rely on digestion and breakdown before nutrients can be used
- Powders offer flexibility but require mixing and preparation
- Liquids are already dispersed, making them easier to take consistently for some people
Liquid formats, particularly micellised liquids, are designed to mix more readily with digestive fluids. This can be useful for people with sensitive digestion or those who struggle with tablets.
The practical truth: liquid supplements aren’t universally “better”. They simply remove friction for people who value ease, flexibility, and consistency.
Building a Sustainable Winter Routine
Supplements work best when they sit on top of solid daily habits.
- Prioritise regular sleep
- Stay lightly active, even during colder months
- Manage stress where possible
- Eat a varied diet with plenty of whole foods
- Stay hydrated
Once these foundations are in place, targeted nutrition can offer additional support during periods of increased seasonal demand.
