Every winter I see people loading up on supplements to try and avoid getting sick.

What many people don’t realise is that vitamin D deficiency is surprisingly common during winter, especially when we’re spending less time outdoors and getting less sun exposure.

But more isn’t always better.

Here’s what the evidence actually says about the three most talked-about winter nutrients.

1️⃣ Vitamin D

We get less sun exposure during winter, and deficiency is common.

If your levels are low, supplementation can help support normal immune function.

If your levels are already optimal, taking more doesn’t appear to provide additional immune benefits.

2️⃣ Zinc

Among these three nutrients, zinc has some of the strongest evidence.

When taken early in the course of an illness, zinc may help reduce how long symptoms last.

It appears to support the body’s ability to recover more efficiently.

3️⃣ Vitamin C

Many of us grew up believing vitamin C could prevent every cold.

The research tells a more nuanced story.

Vitamin C may slightly reduce symptom duration in some people, but it doesn’t reliably prevent illness.

The bigger picture?

Supplements are exactly that: supplements.

They work best when they’re filling a genuine gap.

Your immune system relies on much more than a pill.

🌟 Quality sleep

🌟 Regular movement

🌟 Stress management

🌟 A healthy gut

🌟 Adequate protein

🌈 Plenty of colourful plant foods

Build the foundation with REAL FOOD FIRST.

Then use supplements strategically when needed.

If your levels are already fine, supplementing won't strengthen your immune system. It'll just make expensive urine. The research on this is clearer than most supplement brands want you to know.

Every winter we see the exact same panic buying in the supplement aisles.

People load up their carts with high dose immune complexes hoping to buy their way out of catching whatever bug is going around school or the office.

But we need to look at what the clinical evidence actually supports.

Let's break down the big three winter nutrients.

➡️ Vitamin D
This is the one I prioritise FIRST for a very simple reason. We simply are not getting the same sun exposure during the colder months and deficiency becomes highly common. Vitamin D regulates immune cell function directly. But the catch is that it only provides real benefit if you are actually deficient to begin with.

➡️ Zinc
The research backing zinc is actually quite strong when we look at symptom management. Taking it appropriately at the very first sign of a scratchy throat or fatigue can help reduce how long those cold symptoms linger.

➡️ Vitamin C
This one gets a massive amount of attention every single winter. The truth is the evidence is incredibly modest. Gulping down a massive dose of vitamin C will not magically stop you from catching a virus if your body is already completely exhausted.

Supplements have a valid place in clinical nutrition.

But they only work effectively when your foundation is already built.

A supplement will never outwork a diet that lacks PLANT DIVERSITY or a lifestyle running on four hours of sleep. Your gut microbiome plays a massive role in regulating your immunity and that requires ACUTAL food.

Things like colourful vegetables, legumes, bone broth and adequate hydration.

Build the foundation first with real food. Then we use supplements to fill the specific gaps.

What we all know is that winter brings bugs, and we have to be ready. When you have kids in school or daycare, exposure is simply part of reality. You can eat well, take the supplements, go to bed on time, and still end up sick for ten days. The goal isn't to never get sick—it's to recover quickly so life doesn't move on without you.

Just last week, my own house got hit.

One by one, the kids came home with the sniffles and that heavy fatigue. Eventually, the adults caught it too. I didn't panic and I definitely didn't feel like my nutrition background failed me.

We simply shifted our focus to recovery.

I made my Chicken Soup recipe (on my blog) - boiled down a whole chicken with carrots, celery, onion, and garlic for a massive pot of noodle soup. I used the leftover bones for broth to use later in the week. We focused heavily on the basics that actually support the immune system when it is under heavy stress.

Here is what we prioritised to bounce back:
🌟 SLEEP. Resting when we can and aiming for 7 to 8 hours consistently because recovery happens when you actually REST.
🌟 Real HYDRATION. Plain water is the foundation but we also lean heavily on electrolytes. I use a brand called Sodii because it has the sodium, potassium, and magnesium we actually need without the sugar fillers.
🌟 Nutrient DENSITY. We kept adding colourful plants and fibre to our meals. Frozen vegetables work perfectly here and save so much money.

We stopped chasing the impossible goal of zero illness.

We focused on building a body that can handle the hit and recover efficiently. Supplements like vitamin D3 and zinc have their place, but they work best alongside strong daily habits like eating diverse foods.

Your body is working hard for you. Support it with warm fluids, real food, and actual rest. It's boring, but the science proves - it WORKS.

You don’t have to suffer through aging — or fight your body to feel good. There are evidence-based ways to support your energy, brain health, hormones, and gut as you age.

What these habits support:
✔ Energy
✔ Brain health
✔ Hormones
✔ Gut health
✔ Healthy aging

1️⃣ Chronic stress and exercise stress are NOT the same
Short bursts of stress from exercise can build resilience. Chronic stress, poor sleep, and overwhelm can increase inflammation over time.

2️⃣ Muscle matters more than perfection
Strength training consistently is one of the best things you can do for metabolic and long-term health.

3️⃣ Protein matters — but so does the training stimulus
You don’t need to obsess over extreme protein targets if you’re resistance training consistently and eating balanced meals.

4️⃣ Omega-3 intake is still one of the biggest nutritional gaps I see
EPA + DHA support brain health, inflammation, cardiovascular health, and recovery.

5️⃣ Creatine isn’t just for the gym
Research continues to show benefits for brain energy, cognition, recovery, and healthy aging — especially in women.

6️⃣ Your gut health influences far more than digestion
The gut impacts inflammation, mood, insulin sensitivity, immune health, and even energy levels.

7️⃣ Broccoli sprouts are tiny nutrition powerhouses
They’re rich in sulforaphane, a compound linked to antioxidant and detoxification pathways.

8️⃣ Movement still matters after poor sleep
You don’t always need to “go hard.” Sometimes lighter movement is enough. Consistency wins long term.

9️⃣ Vitamin D is more than just a “bone vitamin”
It plays a role in immune function, mood, inflammation, and overall health.

🔟 Healthy aging is usually built from boring basics done consistently
Sleep. Movement. Protein. Fiber. Omega-3s. Stress management. Resistance training. Whole foods.

No magic pill. No extreme detox. Just evidence-based habits repeated consistently.

The bodybuilding world owned creatine early—strength gains, fuller muscles, quick scale changes.

And that association stuck.

But the research has moved on.

We now know that women tend to have 70–80% lower creatine stores than men.

This isn’t a flaw.
It just means we’re starting from a different baseline.

More recent research points to something more important:
creatine isn’t about adding more—it’s about restoring energy resilience.

Here’s how daily use actually works:

1. Brain energy buffer
Women have lower creatine in key areas of the brain.
Supplementation helps support mental clarity, focus, and mood—especially under stress.

2. Gut barrier integrity
Creatine provides the energy needed to maintain mucosal barrier function. Colon tissues in IBS patients show reduced creatine transporter levels.

3. Hormonal life stages
Depression risk increases during puberty, the luteal phase, postpartum, and perimenopause.
Research shows creatine may enhance response to SSRIs in women with major depressive disorder.

At 3–5g daily, water retention is minimal (if anything at all).
It does not increase testosterone or cause fat gain.

What I see in practice is subtle—but meaningful:

Clearer thinking - less afternoon fatigue - feeling more like yourself again - along with added energy during training

Not dramatic. Just more like yourself.

Start at 3 grams daily for a month.

Let your body respond. Then reassess.

Protein is important — but we’re starting to take it too far.

Somewhere along the way, the conversation has shifted into “more protein = better results”… and we’re losing sight of what actually matters.

Because protein alone isn’t the goal.

Building muscle is.

And that’s the piece that often gets missed — especially for women in perimenopause and beyond.

If you’re not challenging your body with resistance training, your body has no reason to use that protein to build anything meaningful.

Muscle is one of the most powerful tools we have for:
– supporting metabolism
– improving insulin sensitivity
– protecting bone density
– and maintaining long-term health and independence

This post explains it well — but it’s only part of the picture.

We need to stop focusing on one piece, and start looking at the full strategy. Here are some evidence-based findings about protein requirements.

Women often come to me exhausted and confused because the intermittent fasting protocol they adopted to get healthy is making them feel worse.

They skip breakfast and push through morning workouts. Yet they are completely drained by the afternoon and accumulating belly fat despite doing everything by the book. Their doctors look at their basic blood panels and tell them everything is completely normal.

Your body is actually behaving logically based on its current environment.

Oestrogen acts as a natural brake pedal for your cortisol production. When oestrogen begins to decline during perimenopause, you lose that regulatory brake. Your cortisol levels stay elevated much longer than they used to.

Fasting is a physical stressor. If your cortisol regulation is already compromised by these natural hormonal shifts, adding a rigid 16-hour fast just pours fuel on the fire. You spend the entire first half of your day in a sustained stress response.

Your body interprets this combination as a threat to your survival. It responds by holding onto calories and storing fat specifically around your midsection where cortisol receptors are highly concentrated.

There is also a significant structural issue with muscle preservation.

➔ Protecting your muscle mass right now requires hitting a specific threshold of about 30 grams of protein multiple times throughout the day.

Compressing your food intake into a small eight-hour window makes hitting those necessary protein targets incredibly difficult without feeling uncomfortably full.

You do not have to force a massive fasting window that adds friction to a system already working overtime.

A gentle 12-hour overnight window usually works beautifully. Finish your dinner at 7 PM and eat a protein-rich breakfast at 7 AM. This gives your gut the overnight rest it needs without triggering an aggressive cortisol spike.

This is the kind of meal I come back to again and again.
Simple ingredients lots of plants and something the whole family will eat. I’ve broken it all down in my latest blog: successfuelnutrition.co.nz/minestrone-soup-for-kids

I stopped reaching for vitamin C supplements years ago when my kids started showing the first signs of a winter cold.

Because the data clearly shows that 70 to 80 percent of immune cells actually reside in the gut.

When my son was getting frequent colds a few winters back, I did what most parents naturally do. I bought the chewable supplements, pushed the citrus, and just waited for him to get better. Then I started looking deeply at the clinical data on gut health and immune function in children.

The maturation of immune cells and the gut microbiome occur simultaneously in early life. They adapt together. When you support the digestive system, you strengthen the immune response directly.

That realisation led me to develop a specific minestrone recipe for our family.

It delivers prebiotic fibre that feeds beneficial gut bacteria while providing easily digestible nutrients when kids are fighting illness. Best of all, it tastes good enough that my son and daughter actually eat it without complaining.

Research from the American Gut Project found that people consuming 30 or more different plant types per week have significantly more diverse gut microbiomes. Different plant fibers feed different species of beneficial bacteria.

Here is what goes into my base recipe:
➢ Celery, carrots, leeks, onions, garlic, tomatoes, and potatoes
➢ Oregano and basil for additional prebiotic benefits
➢ Cannellini beans, fresh kale, and organic durum wheat pasta

That gives you 13 different plants in one single meal.

I build the flavour foundation by frying quality bacon without added sugars. Then I add the finely chopped aromatics. Onions, garlic, and leeks provide prebiotic fibres that promote the growth of beneficial bifidobacteria.

I use a combination of vegetable stock and high quality bone broth made from grass fed beef. The bone broth contains amino acids like glutamine that support intestinal barrier function and provide cellular energy for activated immune cells.

I just let this simmer gently for a few hours.

The goal here is absolutely realistic. You cannot prevent every single cold your children encounter. Children actually need exposure to build immune resilience over time.

But when I see the first sniffle and make a batch of this soup, my kids sleep better and bounce back much faster than they used to.

Consistency builds resilience.

I actually build my recipes backward.
I start with the gut and work my way up to the dinner table.

When I put together the new Pearl Couscous Salad for the blog I had a very specific metabolic target in mind. I wanted to keep in mind my goal for 30 different plant varieties a week while keeping the protein high enough to actively support muscle maintenance for women in midlife.

Hitting that many plants usually means making a complex dish that kids absolutely refuse to touch.

So I had to engineer the flavours to work for an entire family sitting together at the end of the day. The pearl couscous provides a comforting and familiar base that easily anchors the more complex fibres and micronutrients. You get the clinical benefits of massive plant diversity without having to cook two separate meals when you are already exhausted.

Restriction simply doesn't build strength. Nourishment does.

Having a strong gut foundation genuinely changes how your body handles daily stress and sleep. This recipe is just a highly practical way to get that foundation built on a random Tuesday night.
