At Bigvits, care comes first. This time of year, our days get colder, our calendars get busier, and our immune systems work overtime. Between early starts, office parties, school concerts, late-night wind-downs, and more time indoors, staying well can feel like a full-time job.

That’s where small, supportive steps make the biggest difference.

We’ve brought together trusted essentials from premium brands — the vitamins and herbal heroes that help you stay well through flu season, festive socialising, and the winter months ahead. Simple routines. Real-life support.

Below, you’ll find five of our most-loved immune-support picks, each with easy usage tips designed to fit effortlessly into your day.

Healthy Origins Vitamin D3 (10,000 IU): Sunshine Support for Darker Days

When daylight disappears early, and we’re mostly indoors, Vitamin D drops — fast. Vitamin D3 is essential for immune health, mood, and daily vitality, which is why it’s one of our most-loved winter staples.

Healthy Origins delivers a clean, potent formula ideal for those who need a stronger boost during the darkest months.

How to use it:

Best time: Take with your biggest meal of the day — Vitamin D3 loves healthy fats.

Avoid with: No major interactions.

Real-life tip: If it gives you a little energy kick, stick to morning or lunchtime doses.

NOW Foods Vitamin C Crystals: Your Everyday Immune Essential

Vitamin C is a classic for a reason: it supports immune defences, fights oxidative stress, and helps your body feel its best through colder months.

NOW’s Vitamin C Crystals make it easy — sprinkle into water, tea, juice, or your morning smoothie.

How to use it:

Best time: Morning or early afternoon to support natural energy rhythms.

Avoid with: Taking on an empty stomach if you’re sensitive — pair with food if needed.

NOW Foods Echinacea (400mg): Short-Term Support When You Need It Most

For the moments you start feeling run-down — the scratchy throat, the tired afternoon slump — Echinacea can be a supportive herbal choice.

NOW’s 400mg capsules are simple, clean, and ideal for seasonal use.

How to use it:

Best time: Split AM + PM doses for balanced support.

Avoid with: Caffeine if you’re sensitive — some people feel lightly stimulated.

Real-life tip: Use it in focused periods (1–2 weeks), such as when everyone around you seems to be sniffling.

MaryRuth’s Elderberry Drops: A Winter Favourite for All Ages

Elderberry has long been used for seasonal wellness. These liquid drops are easy to take and gentle on the stomach — ideal for families or anyone who prefers a liquid supplement.

How to use it:

Best time: Anytime — add to water or tea, or take directly.

Avoid with: Very hot drinks (to protect nutrient quality).

Real-life tip: Use daily during high-contact periods — office gatherings, holiday travel, busy classrooms.

NOW Foods Zinc Picolinate (50mg): A Key Mineral for Winter Wellness

Zinc supports immune function, skin health, and overall resilience — especially when winter colds are making the rounds.

NOW Foods Zinc Picolinate is a trusted, no-frills essential.

How to use it:

Best time: Always with food — zinc can cause nausea if taken on an empty stomach.

Avoid with: High-calcium foods (milk, yoghurt, cheese) at the same time — take them a couple of hours apart.

Small Steps That Make Winter Feel Easier

Supplements help — but lifestyle matters, too. Here are simple, real-life habits that support your immune system naturally:

• Sleep well: 7–9 hours nightly keeps your immune system alert.
• Stay hydrated: Indoor heating dries you out, making you more susceptible to illness.
• Move daily: Even a short walk boosts circulation and immunity.
• Eat seasonal, colourful foods: Berries, citrus, leafy greens, and veg are your friends.
• Wash hands often: Especially during festive gatherings — it’s simple but highly effective.
