Immune Support

The wellness industry markets immune "boosting" with claims that outrun the evidence. The honest version: support helps in specific moments, around travel, recovery from illness, documented deficiencies, not as a substitute for sleep, nutrition, and stress management.

IN SHORT

Immune support is most useful in specific contexts, around travel, recovery from illness, or documented deficiencies, not as general boosting. At PHI in Beverly Hills, board-certified physicians Dr. Faisal Lalani and Dr. Nadiv Samimi offer IV therapy and peptide therapy as supportive care, alongside primary care for any underlying concerns.

When Immune Support Actually Makes Sense

The wellness industry has heavily marketed immune support, often with claims that exceed evidence. Before getting into specifics, we want to be honest about when immune support actually adds value and when it does not.

Immune support is most useful in specific contexts: around travel, particularly international travel or travel during illness peaks; during recovery from illness, when immune function may be temporarily depleted; for documented vitamin or mineral deficiencies; and during periods of high stress or sleep disruption. It is less useful when used as a substitute for sleep, nutrition, exercise, and stress management, or marketed for general boosting without a specific reason. The immune system is complex, and what matters is appropriate immune function for your situation, not maximum immune activity.

What This Page Is and Isn’t

PHI is an interventional pain and regenerative medicine practice. We are not immunologists, infectious disease specialists, or primary care providers. For patients with frequent illness, suspected immune dysfunction, or autoimmune concerns, the appropriate first step is primary care evaluation, sometimes with specialist referral. PHI’s offerings are supportive optimization that may complement broader care, not primary immune evaluation.

When Immune Support May Help

Common scenarios where IV therapy or peptide therapy may be useful include pre-travel preparation in the days before international travel; post-illness recovery, when IV nutrient therapy may address depletion of vitamins, minerals, and hydration; during seasonal illness peaks; for patients with documented vitamin deficiencies such as vitamin D or zinc, where IV repletion may produce higher tissue levels than oral supplementation; for high-stress or sleep-disrupted periods; and for longevity-focused patients addressing immune system aging as part of overall aging.

How PHI Approaches Immune Support

The first step is comprehensive evaluation: a detailed history of why you are considering immune support, discussion of any underlying patterns such as frequent illness or planned travel, an assessment of whether primary care evaluation should come first, and a recommendation matched to your context.

IV therapy delivers immune-relevant nutrients directly into circulation; common immune-focused protocols include high-dose vitamin C, glutathione, zinc, and B-complex vitamins, with IV delivery producing higher tissue levels than oral supplementation when rapid repletion is desired. Peptide therapy uses specific compounds, some of which may support immune function; we discuss specific peptides individually without listing them publicly, including evidence base and regulatory considerations. These are delivered in our clinic setting, and we coordinate with primary care for evaluation of underlying causes when something more than supportive optimization is warranted.

When to See Someone, and Where

You may benefit from PHI’s offerings if you have specific contexts where immune support adds value (travel, post-illness, documented deficits, high-stress periods), if you are pursuing comprehensive longevity care that includes immune support, or if you have established primary care for any underlying concerns.

You should pursue primary care evaluation first if you are getting sick more frequently than expected, have recurrent or severe infections, have suspected autoimmune symptoms, or have unexplained fatigue alongside illness susceptibility. These warrant proper medical evaluation rather than wellness intervention.

Why PHI for Immune Support

i.

Two board-certified physicians

Dr. Faisal Lalani and Dr. Nadiv Samimi both trained in interventional medicine at Cedars-Sinai and bring medical rigor to wellness optimization.

ii.

Honest framing

We do not market immune boosting with claims that exceed evidence. We are frank about when immune support adds value and when it is better directed elsewhere.

iii.

Physician-supervised, clinic-setting delivery

IV therapy and peptide therapy are delivered in our clinic setting under physician supervision.

iv.

Evidence-aware selection

Specific peptides and IV protocols have specific applications. We recommend based on clinical situation rather than offering everything available.

v.

Coordination with primary care

PHI’s immune support works alongside your primary care for any underlying concerns, not as a substitute.

vi.

Concierge, coordinated care

Single-physician continuity from consultation through treatment and return to activity. Patients receive clear guidance and transparent pricing at consultation.

Frequently Asked Questions

Not reliably. IV therapy may support immune function during high-risk periods such as travel or illness exposure, and may speed recovery if you do get sick, but it does not reliably prevent illness. Patients who use IV therapy for travel often appreciate it; whether it actually prevents illness is hard to demonstrate.

Treatments We Offer for Immune Support

PHI offers supportive optimization treatments for immune function in specific contexts. Your physician will recommend the right options based on your specific situation.
