IV Therapy.

Physician prescribed after evaluation · Longevity Gyms · Updated 2026

Delivering nutrients intravenously bypasses digestion entirely and achieves close to complete bioavailability. That is real pharmacology. It is also unnecessary for most healthy people with a working gut, and we will tell you which category you are in.

  • Prescribed after evaluation, not selected from a drip menu
  • Indicated by findings such as documented deficiency or malabsorption
  • Administered by clinical staff under sterile conditions
  • We will recommend against it where oral would do the same job

What It Is

Route changes everything.

When you swallow a nutrient it has to survive stomach acid, cross the intestinal wall, and pass through the liver before it reaches circulation. How much arrives varies by nutrient, by dose, and by the person. For some, absorption is the limiting factor rather than intake.

Intravenous delivery skips all of that. The nutrient enters circulation directly, at close to complete bioavailability, at concentrations oral dosing cannot reach. That is a genuine pharmacological difference, and it matters most when absorption or concentration is the actual problem.

How We Approach It

A reason, then a drip.

Most IV clinics run this in the opposite order. You choose a bag from a board, someone places a line, and nobody establishes whether you needed it. We do it the other way around, and that changes what the service actually is.

We Establish A Reason

Step one · findings first

Documented deficiency, impaired absorption, a clinical situation where oral intake is insufficient, or recovery from something specific. Without one of those, intravenous delivery is a more invasive route to the same result.

  • Labs reviewed or ordered where they inform the decision
  • Absorption and gut history considered, not assumed
  • Findings drive the formulation rather than a package name

We Check It Is Safe

Step two · screening

Kidney and cardiac function, current medications, and history are reviewed before anything is prescribed. High dose intravenous nutrients are not benign, and some carry real considerations including renal load and vein irritation.

  • Renal and cardiac status considered before dosing
  • Medication interactions reviewed
  • Certain conditions rule this out entirely

We Administer Properly

Step three · delivery

Sterile preparation, clinical staff, and monitoring throughout. Intravenous access carries infection and infiltration risk regardless of what is in the bag, which is why the setting matters as much as the contents.

  • Prepared and administered under sterile conditions
  • Monitored for the duration of the infusion
  • Rate adjusted to what you tolerate

We Recheck

Step four · and then stop

If we treated a documented deficiency, we retest to confirm it corrected. Repletion has an endpoint. Indefinite weekly infusions with no measured target is not a protocol, it is a subscription.

  • Markers rechecked at a defined point
  • Oral maintenance where it will hold the result
  • Stopping is the expected outcome, not a failure
The Landscape

Where the evidence actually sits.

IV nutrient therapy has become one of the most marketed services in wellness and one of the least evenly evidenced. Both parts are worth stating.

01

The bioavailability difference is real

Nutrients delivered intravenously reach systemic circulation without passing through digestion, achieving virtually complete bioavailability. This is established pharmacology, not a marketing claim, and it is the entire legitimate basis for the route.

02

The evidence is strongest in targeted situations

Peer reviewed reviews support intravenous delivery in defined clinical scenarios: documented deficiency, malabsorption disorders, dehydration, and recovery from surgery or illness. Evidence for use in generally healthy people seeking a wellness effect is limited, and we will not pretend otherwise.

03

Regulators have not approved wellness claims

The FDA has not approved intravenous vitamin therapies for general wellness indications. Claims about immunity, energy, detoxification, or hangover relief circulate widely in this industry and are not supported by that standard of evidence. We do not make them.

Who It Is For

And who it is not for.

Being direct about this saves you a consultation fee and saves us a conversation neither of us needs.

People with a documented deficiency that oral supplementation has not corrected

Those with malabsorption, a relevant gut condition, or a history of bariatric surgery

Recovery from illness, surgery, or a period where intake has genuinely been inadequate

Anyone who wants the evidence explained plainly rather than a wellness pitch

Not for healthy people with a working gut, where oral will do the same job

Not appropriate with certain kidney or cardiac conditions, or during pregnancy

The Pathway

What actually happens.

A clinical process with an evaluation at the front and an endpoint at the back.

01
First

Evaluation

  • History, medications, and current supplements reviewed
  • Existing labs used, or ordered where they inform the decision
  • Kidney and cardiac considerations assessed before anything is dosed
  • You may leave with a recommendation against, which is a valid result
02
Then

The Infusion

  • Formulation prepared to your prescription under sterile conditions
  • Line placed by clinical staff, seated comfortably throughout
  • Typically thirty to sixty minutes depending on what is prescribed
  • Monitored for the duration, with the rate adjusted to tolerance
03
Then

Recheck & Stop

  • Markers rechecked at a defined point to confirm correction
  • Transition to oral maintenance where that will hold it
  • Coordinated with your other physicians on request
  • Course ends when the reason for it does

What This Service Provides

Stated as process, not outcomes.

We describe what we do rather than what any infusion will achieve, because the second depends entirely on whether the first was warranted.

01

A physician evaluation determining whether intravenous delivery is warranted at all

02

Review of labs, absorption history, medications, and relevant organ function

03

Formulation built from findings rather than selected from a menu

04

Preparation and administration under sterile clinical conditions

05

Monitoring throughout the infusion, with rate adjusted to tolerance

06

Rechecking of markers to confirm whether the deficiency corrected

07

Transition to oral maintenance where it will hold the result

08

A clear recommendation against, where that is the honest answer

How It Fits Your Protocol

Clinical, and finite.

IV therapy does not sit inside a Circuit. It runs alongside your protocol as a clinical service, and unlike most things here it is meant to end.

Step One

We measure first

Diagnostics come before any clinical conversation. Without a documented finding there is nothing to correct, and correcting nothing is what most of this industry sells.

Step Two

We try the simpler route first

Where oral supplementation, dietary change, or addressing an absorption issue would achieve the same result, that is what we recommend. Intravenous is the answer when the simpler route has failed or cannot work.

Step Three

We finish

Markers are rechecked, the deficiency is confirmed corrected, and the course ends. Where maintenance is needed we move you to the least invasive route that holds it.

The Science Behind It

Real pharmacology, specific applications.

The route is genuinely different. Where that difference translates into benefit is narrower than the industry suggests, and these are the papers that set out both.

Nutrients administered intravenously have virtually complete bioavailability, entering systemic circulation without being subjected to digestive processes. That advantage is real, and it matters most when absorption is the actual problem.

Where We Stand

The route is real. The indication has to be too.

Read those papers and you will find a consistent picture. Intravenous delivery achieves what it claims pharmacologically, and the clinical evidence supports it in targeted scenarios rather than as a general wellness intervention. That is why this page has no drip menu and no list of packages. If your evaluation shows a reason, we will treat it and then stop. If it does not, we will tell you, and you will have saved money.

Frequently Asked

Questions answered.

What drips do you offer?

We do not run a drip menu. What is prescribed depends on what your evaluation finds, and building formulations from findings rather than from packages is the difference between this being a clinical service and a retail one.

Will this boost my immune system?

We will not phrase it that way. Correcting a genuine deficiency in a nutrient your immune system depends on is a real thing. Infusing nutrients you are not short of, in the hope of boosting a system that is already working, is not, and the evidence does not support it.

Can I come in for a hangover?

No. That is a common offering in this industry and it is not one of ours. Fluids help dehydration, which you can achieve by drinking water, and none of it requires a physician or a cannula.

Is it not just expensive urine?

A fair challenge and often true. If you are already replete, your kidneys will clear the excess of water soluble nutrients, and you will have paid for the privilege. If you are genuinely deficient and not absorbing orally, that is a different situation entirely. Establishing which one applies is the point of the evaluation.

Do I need labs first?

In almost all cases yes. Without a documented finding there is nothing to correct and no way to know whether it worked. If you have recent labs, bring them and we will use them rather than repeating work.

Is it safe?

When properly indicated, prepared, and administered, it is well tolerated. It is not risk free. Intravenous access carries infection and infiltration risk, and high dose nutrients can place load on the kidneys or irritate the vein. Screening and sterile technique are how those risks are managed.

How often would I need it?

As few times as it takes to correct what we found. Repletion has an endpoint, and once markers confirm correction we move you to the simplest route that maintains it. Ongoing indefinite infusions without a measured target is not something we offer.

Is it covered by insurance?

Generally not, as most of this is elective. Some diagnostics may be eligible for HSA or FSA reimbursement, and we can provide documentation for submission.

Is it included in membership?

No. IV therapy is a clinical service with its own evaluation and its own endpoint. It sits alongside membership rather than inside a Circuit.

The First Step

Reserve Your Consultation.

This begins with an evaluation rather than an infusion. In it we will:

  • Review your history, medications, and current supplements
  • Determine whether labs are needed before anything is prescribed
  • Assess whether oral would achieve the same result
  • Tell you plainly whether this is warranted for you
  • Set an endpoint rather than an open ended arrangement
