Is MS Making You More Prone to Infections? Supplements That Support Immune Resilience

🧬 Why People with MS May Be More Susceptible to Infections

MS is an autoimmune disease—meaning your immune system mistakenly attacks your own nervous system. But that doesn’t mean your immune system is “strong.” In fact, it’s often dysregulated, and people with MS may experience:

More frequent infections (respiratory, bladder, etc.)
Slower recovery from colds, flu, or COVID-19
Increased infection risk from MS medications
Greater likelihood of chronic inflammation and poor immune surveillance

⚠️ Key Reasons MS Increases Infection Risk

Immunosuppressive Medications
Treatments like Ocrevus, Gilenya, and steroids reduce immune system activity to control MS flares—but they also lower defenses against viruses and bacteria [1].
Bladder and Urinary Dysfunction
MS often causes urinary retention or incomplete voiding, making you prone to urinary tract infections (UTIs).
Impaired Mobility and Lung Function
Reduced physical activity and weakened chest muscles increase risk for respiratory infections, especially during cold and flu season.
Chronic Inflammation and Oxidative Stress
Long-term inflammation weakens your immune response, depletes nutrients, and damages tissue.
Poor Sleep and Nutrient Deficiencies
MS fatigue, poor diet, and disrupted sleep all lower immune strength.

🌿 Supplements That May Support Immune Resilience (Without Overstimulation)

For people with MS, the goal is not to “boost” the immune system—but to support its balance and resilience.

Here’s a breakdown of research-supported supplements that may help:

🌞 1. Vitamin D3

Why it matters:
Low vitamin D is strongly linked to MS development, progression, and poor immune function. It plays a regulatory role by calming overactive immune cells while enhancing pathogen-fighting ones [2].

Reduces inflammation
Supports immune regulation
May lower risk of respiratory infections

Suggested dose: 2,000–5,000 IU/day (check blood levels)

🥬 2. Zinc

Why it matters:
Zinc is critical for white blood cell function, wound healing, and antiviral defense. Deficiencies are common in people with chronic conditions like MS.

Helps fight viral and bacterial infections
Supports mucosal immunity (sinus, lungs, bladder)
Regulates inflammation and autoimmune reactions

Suggested dose: 15–30 mg/day
⚠️ Don't exceed 40 mg/day without supervision—high doses can cause copper deficiency.

🧪 3. Selenium

Why it matters:
Selenium helps the body produce antioxidant enzymes that protect immune cells from damage.

Enhances T-cell activity
Supports viral clearance
Protects against oxidative stress

Low selenium levels have been linked to increased MS severity and worse immune outcomes [3].

Suggested dose: 100–200 mcg/day (as selenomethionine)

🦠 4. Probiotics and Prebiotics

Why they matter:
A healthy gut microbiome is key to immune homeostasis. MS is associated with gut dysbiosis, which can weaken immune regulation.

Improve mucosal defenses in the gut and lungs
Reduce chronic inflammation
Enhance Treg cell activity (immune tolerance)

Look for blends containing:

Lactobacillus rhamnosus
Bifidobacterium lactis
Prebiotics like inulin or FOS

Suggested dose: 10–50 billion CFUs/day

💊 5. N-Acetyl Cysteine (NAC)

Why it matters:
NAC supports the production of glutathione, your body’s master antioxidant. It’s also mucolytic—helping clear the lungs and reduce oxidative stress.

Enhances respiratory defense
Supports detoxification
May reduce MS-related inflammation

Suggested dose: 600–1,200 mg/day

🧘 6. Adaptogens (Ashwagandha, Rhodiola)

Why they matter:
Adaptogens help the body adapt to stress, which otherwise suppresses immune function.

Reduce cortisol-induced immune suppression
Improve energy and stress resilience
May support immune balance in autoimmunity

Ashwagandha has been shown to enhance natural killer (NK) cell activity—important for fighting viruses [4].

Suggested dose:

Ashwagandha: 300–600 mg/day
Rhodiola: 200–400 mg/day

🐟 7. Omega-3 Fatty Acids (EPA/DHA)

Why they matter:
Omega-3s are anti-inflammatory fats that support immune flexibility and protect cells from inflammatory damage.

Reduce cytokine storms
Promote immune cell membrane integrity
May lower MS relapse rates

One study found that omega-3s improved immune recovery and lowered infections in hospitalized patients [5].

Suggested dose: 1,000–3,000 mg of EPA/DHA daily

🌿 8. Elderberry (Sambucus Nigra)

Why it matters:
Elderberry contains antiviral flavonoids and supports upper respiratory immune defense.

Shortens duration of cold and flu
Supports cytokine balance
Safe for short-term use in people with MS

Suggested dose: 300–600 mg/day (avoid long-term use in active autoimmunity)

🍄 9. Medicinal Mushrooms (Reishi, Turkey Tail)

Why they matter:
Mushrooms contain beta-glucans that modulate immune activity without overstimulation.

Improve white blood cell function
Support respiratory tract immunity
Act as immune adaptogens

Reishi has shown potential in balancing Th1/Th2 immune responses in autoimmune conditions [6].

Suggested dose: 500–1,500 mg extract/day (standardized)

🍋 10. Vitamin C

Why it matters:
Vitamin C helps stimulate neutrophil activity, reduce oxidative damage, and regenerate other antioxidants like vitamin E.

Lowers duration and severity of colds
Supports barrier function in lungs and bladder
Works synergistically with zinc and selenium

Suggested dose: 500–1,000 mg/day (split doses for better absorption)

🚫 What to Avoid: Overstimulation

Not all “immune-boosting” supplements are MS-friendly. Avoid:

❌ High-dose echinacea (may trigger flares)
❌ Excessive colloidal silver (toxic long-term)
❌ Stimulant-based immunity drinks or sprays

Always consult your doctor before adding immune supplements—especially if you're on immunosuppressants or biologics like Ocrevus or Tysabri.

🛡️ Lifestyle Habits That Build Immune Resilience

Supplements are helpful, but the foundation of immune health is lifestyle.

✅ Sleep

Aim for 7–9 hours of restful sleep to allow for immune repair.

✅ Movement

Even gentle exercise (walking, stretching) supports lymph flow and immune cell circulation.

✅ Hydration

Proper hydration helps detox the body and keep mucous membranes moist.

✅ Anti-inflammatory Diet

Prioritize:

Leafy greens, berries, omega-3 rich fish
Reduce ultra-processed foods and added sugars

✅ Wash Hands and Practice Hygiene

Especially important if you're on immunosuppressants or in public spaces.

⚠️ When to Talk to Your Doctor

Speak with your healthcare team if you:

Have repeated infections (e.g., 3+ UTIs per year)
Take a disease-modifying therapy (DMT) like Ocrevus, Gilenya, or Lemtrada
Plan to start a new supplement regimen
Notice wounds healing slowly or frequent cold sores

Your neurologist may recommend immune monitoring, lab testing, or preventive measures like vaccinations or antivirals.

🧠 Final Thoughts: Build Immune Resilience Without Triggering Your MS

MS doesn't always mean your immune system is stronger—it often means it's more confused. Supporting your immune system with targeted, gentle supplements can help reduce infections and improve recovery, especially during stress or seasonal illness.

Look to nutrients like vitamin D, zinc, probiotics, NAC, and omega-3s for a smart, MS-safe immune strategy. Pair them with movement, hydration, sleep, and gut health to stay strong without overstimulation.
