Your immune system is your body’s natural defense network — protecting you from everyday stressors, germs, and seasonal bugs. But even the strongest immune system can use extra support, especially when life gets busy or the seasons change.
At Organika, we believe that immune health starts with daily nourishment. From tried-and-true classics like Vitamin C and Zinc to whole-body support with Bone Broth and Collagen, here are some of the best vitamins and supplements for immune system support — for both adults and kids.
A must-have for every wellness routine, Vitamin C supports the production of white blood cells and helps protect against oxidative stress. It’s a powerful antioxidant that keeps your immune system functioning at its best.
Try: Organika® Vitamin C 1000mg Instant C, D, Zinc Immunity — a convenient, high-potency formula that helps you stay strong all year long.
Bonus Tip: Take it daily to help shorten the duration of colds and support healthy skin and tissue repair.
Zinc plays a crucial role in immune defense and helps your body heal and recover. Low zinc levels can weaken immunity, making it an essential daily nutrient.
Try: Organika® Zinc with Vitamin C Chewable Tablets — a delicious, easy way to support your immune system on the go.
Perfect for: Adults and kids needing an extra layer of protection during cold and flu season.
Vitamin D3 helps regulate immune response and supports bone health — but many people don’t get enough, especially in Canada’s darker winter months.
Try: Organika® Vitamin D3 Drops — simple, effective, and family-friendly.
When to take it: Year-round, especially from October to April when sunlight exposure is low.
A healthy gut equals a strong immune system. Around 70% of your immune cells live in your digestive tract, and probiotics help keep that environment balanced and thriving.
Try: Organika Probiotic Family — formulated for the whole family with 16 active strains that promote digestive and immune health.
Tip: Take daily with meals to maintain a healthy gut microbiome.
Rich in antioxidants and vitamins, Elderberry is known for its ability to support the body’s natural defenses and help shorten the duration of colds.
Try: Organika Kids Elderberry + Kids Canadian Bee Propolis Spray with Elderberry — a parent-approved, kid-loved immune boost that’s safe, tasty, and effective.
Great for: Daily immune maintenance and back-to-school wellness.
Bone Broth is a whole-body wellness essential that supports the gut, joints, skin, and immunity. It’s rich in amino acids, collagen, and minerals that help repair and strengthen the body.
Try: Organika® Bone Broth Protein Powder — available in Beef, Chicken, and Veggie varieties. Each serving delivers 15g of protein to help nourish your immune system and recovery.
Enjoy it: In soups, smoothies, or simply mixed with hot water for a soothing cup of nutrition.
Strengthening your immune system isn’t about one magic pill — it’s about building healthy habits. With Organika’s natural, science-backed supplements, you can give your body daily support from the inside out.
Education leads to confidence, and confidence leads to consistency.

Vitamin C is an essential micronutrient. Without it, we are at risk for poor immune function, skin health issues, and joint problems. The many benefits of vitamin C consumption are well known and continuously studied, and its effects on the immune system are top-of-mind, especially in the past year. In this article, we’ll examine some of the ways vitamin C benefits your immunity. Shop Vitamin C What is our immune system? Our immune system is a massive network in our body, composed of organs, white blood cells and proteins that protect us from viruses, infection, and pathogens. There are also two types of immunity that we have, and it’s important to clarify. Innate immune system: this includes physical, chemical, or cellular defences against pathogens like our tears, stomach acid and mucous membranes. Adaptive immune system: also known as acquired immunity, it is marked by the expansion of T and B lymphocytes (a.k.a. our immune army) that set out to destroy the invader. Simply put, when we get sick once, our body learns what those pathogens look like, and can prepare for the next time. Does vitamin C improve immunity? There are a variety of ways that vitamin C works with our immune system to support, build and boost it. In fact, vitamin C works with both our innate and adaptive immune systems (1) Here are a few ways that vitamin C can support you. 1. Vitamin C helps reduce the length of the common cold and flu Vitamin C is commonly used during cold and flu season to help prevent or reduce the symptoms of these common ailments. One study has shown that supplementing with Vitamin C, beyond diet alone, reduced the number of colds as well as the length in those taking the supplement (2). The reduction in symptoms has been attributed to vitamin C’s antioxidant properties and ability to reduce overall inflammation (3). 2. Vitamin C can aid in wound healing It is important to remember that our immune system isn’t at work only when we get sick. Our immune system also helps us recover from injury and wounds. Vitamin C can help with everything from cuts and scrapes, to sports injuries and surgery. Studies have shown that dosing above the recommended daily allowance (RDA), of 500 to 3000 mg can accelerate recovery (4). 3. Vitamin C helps reduce symptoms from seasonal allergies As an antioxidant, vitamin C can help with general inflammation in the body, as is seen with seasonal allergies. In addition, studies have shown that supplementing with Vitamin C can be helpful to reduce symptoms of hay fever (7). One study shows that supplementing with high-dose vitamin C (2,000mg) daily can lower blood histamine levels. Histamine is typically known for its impact on seasonal allergies, hence the reason we reach for antihistamine medications when we feel the sniffly nose and watery eyes starting! 4. Vitamin C reduces oxidative stress Oxidative stress is when there is an imbalance of free radicals and antioxidants. This typically causes cell and tissue damage, leading to faster aging and illness, including conditions like diabetes, cancer, and heart disease. Vitamin C has been shown to reduce overall oxidative stress in the body (8). Overall, Vitamin C is an essential part of our daily routine, whether through food or supplements. It’s important to remember that under times of stress, if you’re taking certain medication or if you’ve been feeling under the weather, it can be helpful to supplement with vitamin C in higher doses. Many people can tolerate 1,000 mg of vitamin C with no ill effect on their bowels. If your vitamin C intake leaves you running for the washroom, try to halve your dose! Shop Vitamin C
