in Lake Forest, IL
Provider-guided vitamin and mineral infusions for immune health
Personalized Immunity IV Therapy & Nutrient Support
Individualized infusions with professional clinical oversight
Lake Forest Regenesis provides personalized Immunity IV therapy for adults in Lake Forest, Chicago’s North Shore, and Lake County, with recommendations based on each patient’s health history, symptoms, and wellness goals.
Immunity IV therapy combines fluids with nutrients such as vitamin C and zinc that play roles in normal immune function. These nutrients matter, but research has not shown that IV infusions prevent colds or other infections in people who are not deficient.
Care is guided by Allana Bush, FNP-C, a family nurse practitioner with more than 20 years of healthcare experience. Each treatment begins with an individualized evaluation to assess suitability, discuss expectations, and prioritize patient safety.

What Is Immunity IV Therapy?
Understanding immune nutrients and what the research shows
Immunity IV therapy is an intravenous infusion of fluids and nutrients, commonly vitamin C, zinc, and B vitamins, given through a small IV line. The exact formula and dose are determined by your provider.
Vitamin C and zinc both support normal immune function, and deficiencies can weaken the body’s defenses. However, according to the NIH Office of Dietary Supplements, routine supplements probably do little to prevent or treat infections in people who are not deficient. Studies of high-dose IV vitamin C in hospital settings have also shown mixed results.
Everyday immune health depends most on sleep, nutrition, physical activity, recommended vaccines, and good hygiene. IV therapy may be one option to discuss, especially when intake has been poor or a deficiency is suspected.
At Lake Forest Regenesis, this infusion is offered as medically supervised, provider-guided care and may be considered alongside other IV and injection therapy options.
Who Is a Candidate?
Individual health factors that guide treatment suitability
Adults who want provider-guided nutrient and hydration support, such as during travel, busy seasons, or recovery from a minor illness, may wish to discuss this infusion with their provider.
Potential candidates are evaluated based on several factors:
- Overall Health: Medical history, existing conditions, and current medications are reviewed to assess suitability.
- Nutrition and Symptoms: Diet, recent illness, and any known nutrient concerns are considered.
- Realistic Goals: Your provider explains what the infusion can and cannot do for immune health.
Frequent infections deserve a closer look. When appropriate, our functional medicine services can help evaluate underlying causes.
Who Is Not a Candidate?
When Immunity IV therapy may not be appropriate
Treatment may not be recommended for individuals with the following considerations:
- Kidney Disease or Kidney Stones: High-dose vitamin C can increase oxalate, which may raise the risk of kidney stones or kidney injury.
- Certain Inherited Conditions: Some conditions, such as G6PD deficiency or iron overload, may increase sensitivity to high-dose vitamin C and require additional review.
- Active Infection With Warning Signs: High fever, trouble breathing, or worsening illness need medical evaluation rather than an infusion.
- Pregnancy, Breastfeeding, or Medication Interactions: These require individualized review before any IV therapy.
Your safety comes first. Your provider reviews your health history, medications, and risk factors and may recommend postponing treatment, further evaluation, or a different approach.

Important safety considerations and treatment limitations
Immunity IV therapy is an elective wellness treatment. It has not been shown to prevent colds, flu, or other infections in people who are not deficient. Individual responses vary, and treatment carries potential risks, including bruising or irritation at the IV site, infection, and, with high-dose vitamin C, kidney stones or red blood cell damage in people with certain conditions.
This treatment is not intended to diagnose, treat, cure, or prevent disease and should not replace vaccines, medical care for infections, or routine primary care. Patients with persistent or worsening symptoms should seek medical evaluation.
How Immunity IV Therapy Works
Understanding the infusion process and clinical monitoring
During treatment, a small catheter is placed in a vein, usually in the arm, and the fluid and nutrient solution flows into the bloodstream at a rate set by your clinical team.
Vitamin C is an antioxidant used by immune cells, and zinc helps immune cells develop and function normally. IV delivery can raise blood levels of vitamin C higher than oral doses, but higher levels have not been shown to prevent infections in healthy adults. Your provider selects the formula and dose based on your health.
What to Expect During Treatment
Clinical Assessment
Your provider reviews your health history, medications, and symptoms, and may recommend lab testing before treatment.
IV Placement
A trained clinician places a small IV line using sterile technique.
Ongoing Monitoring
Staff monitor how you feel and may slow or stop the infusion if you have discomfort or a reaction.
Follow-Up Discussion
Your provider reviews your experience and whether further care or evaluation makes sense.
Frequently Asked Questions
Common questions about Immunity IV therapy
Will an Immunity IV keep me from getting sick?
Research has not shown that IV vitamins prevent colds or other infections in people who are not deficient. Sleep, nutrition, vaccines, and hand hygiene remain the most reliable ways to support immune health.
What is in an Immunity IV?
A typical formula contains fluids, vitamin C, zinc, and B vitamins. Exact ingredients and doses vary by patient. Your clinical team will review the specific formula with you before treatment.
How long does the infusion take?
Most infusions take about 30 to 60 minutes, depending on the formula, infusion rate, and how you feel during treatment. Your clinical team will give you an estimate and monitor you throughout the session.
Is high-dose vitamin C safe?
For many people it is well tolerated, but high doses are not right for everyone. People with kidney disease, a history of kidney stones, G6PD deficiency, or iron overload need extra caution. Your provider reviews these risks first.
Can Immunity IV Therapy Be Combined with Other Treatments?
Integrating immune support into a personalized wellness plan
Depending on your health history and goals, this infusion may be considered alongside other services such as an Immunity Boost injection or a Vitamin D injection when testing shows low levels. Because these share overlapping nutrients, combinations are reviewed carefully to avoid unnecessary duplication.
At Lake Forest Regenesis, your provider considers your medications, existing conditions, and lab results when available before recommending additional therapies.
When frequent illness, fatigue, or stress are part of the picture, a broader functional medicine approach may help evaluate sleep, nutrition, and other contributors.
Our goal is personalized, medically responsible care that prioritizes your needs rather than adding treatments unnecessarily.
Immune Nutrients by IV

This infusion includes nutrients such as vitamin C, zinc and B vitamins that play roles in normal immune function, with a provider on site for every session.
Potential Benefits of Immunity IV Therapy
Exploring immune nutrients and ongoing research
Vitamin C, zinc, and B vitamins all play roles in normal immune function. Clinical research has not confirmed that IV infusions prevent infections in people who are not deficient. The following areas explain why these nutrients continue to attract interest.
Vitamin C & Immune Function
Vitamin C is an antioxidant that immune cells use to function normally. Regular intake may slightly shorten colds, but it has not been shown to prevent them in the general population.
Zinc & Immune Cells
Zinc helps immune cells develop and communicate. Low zinc can weaken immune defenses, while too much zinc over time can lower copper levels, so dosing is reviewed.
Hydration When Run Down
The infusion includes fluids, which may help when a minor illness has made it hard to eat or drink well. Your provider first rules out symptoms that need other care.
Correcting a Deficiency
When diet or lab testing suggests low nutrient levels, replacing them is an established part of care. Your provider can recommend the most appropriate form and dose.
Support Around Travel
Some patients consider this infusion before or after travel. Patients may report feeling refreshed, but research has not shown that it prevents travel-related infections.
Immune Health Foundations
Sleep, balanced nutrition, physical activity, recommended vaccines, and hand hygiene remain the most reliable ways to support immune health year-round.
