Many people believe that taking a variety of vitamins and minerals is enough to strengthen their immune system.however, according to functional medicine expert Jeffrey Bland, it’s more complex than that.
Bland told CNBC in march 2025 that supplements alone won’t fortify immunity. “These nutrients fill deficiencies, ensuring proper immune function, but they don’t strengthen the immune system like a vaccine,” he said.
Immunity isn’t static.The immune system renews its cells roughly every four months, and lifestyle directly impacts the quality of this renewal. Bland poses a key question: “Do you wont the cells replacing today’s to be as good, better, or worse than what you currently have?”
Instead of relying on supplements, Bland recommends adopting lifestyle principles that promote optimal immunity. “These are simple tips. Think about them daily and apply them. They can substantially impact your immune capacity,” he said.
Embrace the Mediterranean Diet
Nutrition is crucial for regenerating immune cells. Bland considers the Mediterranean diet highly effective for strengthening natural defenses. This diet emphasizes colorful fruits and vegetables, extra virgin olive oil, oily fish, nuts, and seeds. These foods provide antioxidants, healthy fats, and omega-3s, which help reduce oxidative stress and chronic inflammation.
Prioritize Quality Sleep
Insufficient or poor sleep can negatively affect immune cell production. “Our bodies regenerate during sleep,” Bland notes. Aim for seven to nine hours of sleep nightly to improve infection resistance and immune response.
Establishing a relaxing bedtime routine, avoiding screens before sleep, and maintaining consistent sleep and wake schedules are recommended.
Aim for at Least 30 Minutes of Daily Movement
Physical activity stimulates blood circulation and enhances immune response. bland advises daily movement, not necessarily intense sports. Dancing,brisk walking,and light aerobics are good options.
“These aren’t extreme exercises,” Bland said. “These are things that can be done daily and that have a notable impact on how your immune system works.”
stay Hydrated
Hydration is often overlooked but essential for immune function. Drinking at least 1.5 to 2 liters of water daily “allows your body to assimilate nutrients well,” Bland explains. Water also helps eliminate toxins and keeps immune cells healthy.
Emotional well-being significantly impacts immune health. Research indicates that stress and isolation can weaken defenses.
“We certainly know your immune system can smile,laugh,have fun,be at its best,but it can also cry and be sad,” Bland observes. Nurturing positive relationships, practicing gratitude, and laughing more often can improve immunity.
Simple Lifestyle changes for a Stronger Immune System: Q&A with an Expert
Here’s a breakdown of effective lifestyle changes, as recommended by functional medicine expert Jeffrey Bland, to support a robust immune system.
What is the Immune System, and Why Is It So Crucial?
The immune system is your body’s defense against illness.It’s a complex network of cells, tissues, and organs that work together to protect you from harmful invaders like bacteria, viruses, and other pathogens. A strong immune system is critical for staying healthy and fighting off infections.
Can You Simply Take Supplements to boost Immunity?
According to Jeffrey Bland,it’s more complex than just popping a few pills. While supplements can address nutrient deficiencies and support proper immune function, they don’t act like a vaccine. In essence, supplements help ensure that your immune system has the building blocks it needs, but they don’t necessarily “strengthen” it in the same way lifestyle changes do. To quote Bland,”These nutrients fill deficiencies,ensuring proper immune function,but they don’t strengthen the immune system like a vaccine.”
How Often Does the Immune System Renew Itself?
The immune system is constantly regenerating, replacing its cells roughly every four months. This process highlights the importance of lifestyle choices. As Bland points out, the quality of the new cells is directly impacted by the choices you make every day.
What Lifestyle changes Can I Make to Improve My Immune Capacity?
Rather of solely relying on supplements, focus on lifestyle principles that promote optimal immunity.Bland offers several simple yet impactful tips:
Embrace the Mediterranean Diet: This diet is highly effective in strengthening natural defenses.
Prioritize Quality Sleep: Aim for consistent and sufficient sleep.
Aim for Daily Movement: Incorporate at least 30 minutes of physical activity.
Stay Hydrated: Drink adequate amounts of water daily.
Maintain Social Connections: Nurture positive relationships and manage stress.
How Does the Mediterranean Diet Support Immunity?
The Mediterranean diet emphasizes nutrient-rich foods that are beneficial for immune health. It focuses on:
Colorful fruits and vegetables: These provide essential vitamins, minerals, and antioxidants.
Extra virgin olive oil: A source of healthy fats with anti-inflammatory properties.
Oily fish: Rich in omega-3 fatty acids,which help reduce inflammation.
Nuts and seeds: Offer healthy fats, antioxidants, and various micronutrients.
These foods provide antioxidants, healthy fats, and omega-3s, which help reduce oxidative stress and chronic inflammation.
How Much Sleep Do I Need, and Why is it Important?
Adults should aim for seven to nine hours of quality sleep nightly. Sleep is when your body regenerates and repairs itself,including the immune system. Insufficient or poor sleep can negatively affect immune cell production, making you more susceptible to illness. Establishing a relaxing bedtime routine, avoiding screens before sleep, and maintaining consistent sleep and wake schedules are recommended.
What Kinds of Physical Activities Are Best for Boosting Immunity?
You don’t need to be a marathon runner to boost your immune system. Bland advises daily movement, even simple activities. Good options include:
Dancing
Brisk walking
Light aerobics
“These aren’t extreme exercises…these are things that can be done daily and that have a notable impact on how your immune system works,” Bland says.
How does Hydration Affect My Immune System?
Staying hydrated is essential for optimal immune function. Drinking at least 1.5 to 2 liters of water daily allows your body to absorb nutrients effectively. Water also helps eliminate toxins, keeping immune cells healthy and functioning properly.
Emotional well-being is closely linked to immune health.Stress and isolation can weaken your defenses. Nurturing positive relationships, practicing gratitude, and laughing more often can substantially improve immune function. As Bland observes, “We certainly know your immune system can smile, laugh, have fun, be at its best, but it can also cry and be sad.”
