Immunity IV & Tri-Immune Injections in Bend, Oregon | Flow Wellness

Cold and flu season hits fast—and often at the most inconvenient moments. Between work, family, travel, and holiday gatherings, most people don’t have time to be sick. That’s why many Flow Wellness patients in Bend, Oregon add an Immunity IV or Tri-Immune injection to their routine during the months when viral illness is at its peak.

Background: Why Immune Support Matters Most in Winter

Your immune system works overtime during cold and flu season, whether you feel sick or not—fighting off exposure from coworkers, travel, holiday gatherings, and shorter, darker days that already put stress on the body. At Flow Wellness, we take a proactive approach: strengthening your immune defenses before symptoms appear, rather than waiting to treat illness after it hits. That philosophy is the basis for our Immunity IV and Tri-Immune injection—both built around the same core trio of nutrients.

What Is an Immunity IV or Tri-Immune Injection?

Both options deliver the same immune-supporting trio—Vitamin C, Zinc, and Glutathione—directly into the bloodstream for fast absorption.

  • Vitamin C supports white blood cell production, helps neutralize free radicals and inflammation, and strengthens the skin and mucous membranes that act as a natural barrier against viruses.
  • Zinc helps activate T-cells and natural killer cells, may reduce the severity and duration of colds, and supports healthy inflammation levels.
  • Glutathione is a powerful antioxidant that supports detoxification, reduces oxidative stress, and supports immune response at a cellular level.

The Immunity IV delivers this trio as a full infusion. The Tri-Immune injection offers the same three ingredients in a quicker, in-and-out shot for patients who don’t have time for a full IV appointment.

Who Might Benefit from an Immunity IV or Tri-Immune Injection?

These treatments may be worth considering if you:

  • Are regularly exposed to sick coworkers or family members
  • Work in a public-facing role — teaching, healthcare, hospitality, and similar fields
  • Travel frequently, especially by plane
  • Are starting to feel run down
  • Want extra proactive support during peak viral season

What to Expect During Your Visit

The Immunity IV takes approximately 45–60 minutes, including a brief clinical review before treatment begins. The Tri-Immune injection takes about 15 minutes — a good option when you’re short on time but still want the same nutrient support.

  1. Hydrate beforehand — it makes veins easier to access for the IV option.
  2. Eat a light meal beforehand to help keep blood sugar stable.
  3. Wear a short-sleeved shirt for quick, comfortable access.

Your clinical team monitors the infusion or injection throughout to keep the experience comfortable and safe.

How Often Should You Get an Immunity IV or Tri-Immune Injection?

There’s no single right answer, but most patients fall into one of these patterns during cold and flu season:

Occasional support: Before travel, a big gathering, or when you feel a cold coming on, a single Immunity IV or Tri-Immune injection is often enough for a noticeable boost.

During high-exposure periods: Teachers, healthcare workers, and frequent travelers sometimes add a session every 2–3 weeks during the peak of the season.

Ongoing maintenance: Many Flow Wellness patients choose a monthly Immunity IV or Tri-Immune injection throughout cold and flu season, keeping Vitamin C, Zinc, and Glutathione levels consistently elevated. This pairs naturally with Flow Wellness’s Signature IV Membership ($189/month).

Your Flow Wellness clinician can help you decide which cadence fits your exposure risk and schedule.
