Your immune system works like a system, it needs the right fuel to stay strong. Vitamins and minerals play a very important role in keeping immune responses balanced, steady, and ready to act when needed.

Whether you’re choosing whole foods or exploring the best immune system supplement, understanding what your body needs can help you make smarter choices. Solluna include many of these essential nutrients in their formula QUE-1 All, supporting a well-rounded approach to daily immune health.

Let’s walk through the top 10 immune-supporting vitamins and minerals and why they matter.

1. Vitamin C – The Classic Immune Booster

Vitamin C is one of the best vitamins to boost your immune system. In fact, vitamin C deficiency can make you more prone to getting sick. Vitamin C acts as an antioxidant, meaning it can protect your body from toxins that cause inflammation. Getting your intake of vitamin C on the regular is essential for good health because your body doesn’t produce it on its own. It also doesn’t store it for later.

2. Vitamin D – The Sunshine Nutrient

Vitamin D doesn’t just help your body defend itself against infection. It also promotes healing. Vitamin D may delay a virus’s ability to replicate, reduce inflammation and increase your T cell levels.

3. Zinc – Essential for Immune Cell Activity

Zinc supports the growth of immune cells. Beans and nuts are rich in zinc. People often turn to zinc supplements at the first sign of seasonal discomfort, and it’s a common ingredient in the immune system supplements for its well-known benefits.

4. Vitamin A – Supports Barriers and Immune Tissues

Vitamin A supports your white blood cells and the mucus membranes (protective linings that remove foreign particles) in your urinary tract, intestines and lungs. Research shows that this helps keep your immune system at its best by protecting it from potential infections.

5. Vitamin E – A Powerful Antioxidant

Vitamin E protects cells from oxidative stress. Nuts, seeds, and spinach are good sources. Its antioxidant properties help keep the immune system balanced and supported.

6. Iron – Critical for Oxygen Transport

Iron helps carry oxygen to cells so that they can work properly. Lean meats, beans, and fortified cereals provide iron. Low iron levels can weaken the immune response, especially in women and athletes.

7. Selenium – Supports Immune Defenses

Selenium plays a role in antioxidant activity and helps lower cell stress. Brazil nuts are one of the richest sources, but seafood and whole grains also contribute.

8. Vitamin B6 – Supports Biochemical Immune Processes

Vitamin B6 is vital to your immune system. One of its major roles is in producing white blood cells  — the cells that help fight off invaders, like viruses and bacteria. Good sources of vitamin B6 include: Chickpea, Beef and Tofu.

9. Copper – Helps Immune and Enzyme Function

Copper works with other minerals to support cell development. Even though the body needs only small amounts, it’s still essential for overall immune strength. Good Source of Copper is: Nuts.

10. Folate – Supports Cell Production and Repair

Folate helps the body to recreate and repair DNA and supports healthy cell formation. Leafy greens, beans, and fortified foods include folate. When immune cells multiply in response to threats, this nutrient plays a quiet but important role.

How These Nutrients Work Together

Your immune system isn’t powered by one single vitamin—it depends on balance. These nutrients work with each other, supporting different layers of immune defense. For example:

• Vitamin C and E help protect cells

• Zinc and vitamin A support immune cell development

• Vitamin D and selenium help regulate responses

• B vitamins support ongoing energy and cell activity

When even one of these nutrients is too low, your immune defenses may not work at their best.

This is why many people look for supplements that include a broad range of vitamins and minerals rather than just one or two. A well-formulated product—like QUE-1 All—can help fill nutritional gaps when diet alone isn’t enough.

Should Supplements Be Part of Your Immune Routine?

Food should always be the foundation of your nutrition, but supplements can play a supportive role—especially when life gets busy or certain nutrients are difficult to get from meals.

Choosing the best immune system supplements often comes down to transparency, quality, and balanced ingredients. A good option should offer well-studied nutrients without unnecessary fillers. QUE-1 All by Solluna is designed with this idea in mind, giving your body support through a thoughtful mix of vitamins, minerals, and functional ingredients.

Staying consistent with your nutrient intake, whether from food or supplements, can make a real difference in how your body responds throughout the year.
