What Does an Immunity Shot Do?

When people ask, what does an immunity shot do? They are usually looking for something simple: support that helps their body stay resilient during cold and flu season, travel, stress, or high-demand periods.

An immunity shot is a concentrated injection designed to quickly deliver key immune-supporting nutrients. At Flow Wellness in Bend, Oregon, our immunity shot contains vitamin C, zinc, and glutathione—three powerful compounds that work together to support immune defense, antioxidant protection, and cellular recovery.

It is different from an immunity IV, which contains a broader blend of nutrients (including B-complex vitamins and trace minerals). The shot is a fast, efficient option for targeted immune support.

What Does an Immunity Shot Do in the Body?

Your immune system depends on adequate micronutrients to function properly. When levels are low—or when stress increases demand—immune efficiency can decline.

An immunity shot helps:

• Support white blood cell function
• Reduce oxidative stress
• Strengthen antioxidant defenses
• Support faster recovery
• Enhance overall resilience

Because it is administered by injection, nutrients are rapidly available to your system without relying on digestive absorption.

Key Ingredients in an Immunity Shot

1. Vitamin C

Vitamin C is one of the most well-known immune-support nutrients.

Why it matters:

• Supports white blood cell production and activity
• Helps protect cells from oxidative stress
• Supports skin and mucosal barriers (your first line of defense)
• May reduce severity and duration of upper respiratory infections

Vitamin C levels drop quickly during illness and periods of high stress. Replenishing levels supports your body during higher-demand states.

2. Zinc

Zinc is essential for immune cell communication and development.

Benefits include:

• Supports T-cell and natural killer cell function
• Plays a role in antiviral defense
• Assists in wound healing
• Supports inflammatory balance

Even mild zinc deficiency has been associated with increased susceptibility to infections. Adequate zinc helps your immune system respond appropriately and efficiently.

3. Glutathione

Glutathione is often called the body’s “master antioxidant.”

It plays a critical role in:

• Neutralizing free radicals
• Supporting detoxification pathways
• Regulating inflammation
• Protecting immune cells from oxidative damage

When your body is fighting infection or under chronic stress, oxidative load increases. Glutathione helps buffer that stress, supporting immune resilience and recovery.

Low glutathione levels are associated with fatigue, slower recovery, and increased inflammatory stress.

Immunity Shot vs. Immunity IV

Immunity Shot:

• Vitamin C
• Zinc
• Glutathione
• Quick appointment (less than 15 minutes!)
• Ideal for targeted immune boost

Immunity IV:

• Vitamin C
• B-complex vitamins
• Mineral blend (zinc, magnesium, manganese, copper gluconate)
• Broader metabolic and immune support
• Longer infusion session (plan on one hour)

The immunity shot is efficient and convenient. The immunity IV provides more comprehensive support when deeper replenishment is needed.

Can an Immunity Shot Prevent Illness?

A common question is whether immunity shots “prevent” disease.

No injection can guarantee you will not get sick. However, optimizing nutrient levels supports the systems that reduce vulnerability.

An immunity shot may be particularly helpful:

• At the first sign of illness
• Before or after travel
• During high stress periods
• When feeling run down
• During seasonal illness spikes

Supporting immune function early often improves how your body handles exposure.

Who Should Consider an Immunity Shot?

You may benefit if you:

• Frequently feel run down
• Experience recurrent colds
• Have high stress or poor sleep
• Travel often
• Are recovering from illness

At Flow Wellness, we approach immune health proactively. Rather than waiting until you are fully sick, we focus on strengthening the systems that keep you well.

So, What Does an Immunity Shot Do?

An immunity shot delivers vitamin C, zinc, and glutathione directly into your system to support immune cell activity, antioxidant protection, and inflammation balance.

It does not replace sleep, nutrition, or healthy habits. But it can enhance your body’s readiness and recovery when demand increases.

If you are in Bend, Oregon and want to strengthen your immune resilience this season, our clinical team can help you determine whether an immunity shot—or a more comprehensive immunity IV—is the right fit for your goals.
