Sumakase IV Therapy - Doctor's choice IV therapy
Sumakase IV Therapy in Seoul: a 1:1 physician-selected infusion, chosen from over 50 agents after functional-medicine and neurological assessment, given in a private IV room.
Sumakase IV Therapy - Doctor's choice IV therapy
Medically reviewed by Dr.Ho-Sang Yoon, MD, Board-certified Neurologist
Sumakase IV Therapy in Seoul is not a formulation but a selection process: the clinic's own description is personalised 1:1 IV therapy provided according to the medical team's individual approach. Based on functional medicine and neurological examinations, the clinic selects from over 50 types of agent to replenish nutrients assessed as lacking and to regulate nutrient levels. Seoulhoho Hospital is in Gangdong-gu, Seoul, and this service sits within its wider IV infusion programme.
What Is Sumakase IV Therapy?
The distinguishing feature is who chooses and on what basis, rather than what is in any particular bag.
The therapy is 1:1 and personalised, selected by the medical team.
Selection is based on functional medicine and neurological examinations.
More than 50 types of agent are available to choose from.
The stated purpose is to replenish nutrients assessed as lacking and to regulate nutrient levels.
No general or local anaesthesia is needed; the only discomfort is the initial needle insertion into a vein.
Because the preparation is customised per patient, the category-general regulatory context matters here more than on a standard formulation. In the United States, compounded drug preparations are not FDA-approved, which means the agency does not verify their safety, effectiveness, or quality before they are marketed; the FDA's position is that compounded preparations should be used where an FDA-approved drug is not medically appropriate, that unnecessary use may expose patients to serious risks, and that quality standards differ according to the setting in which compounding takes place. A patient anywhere considering a customised infusion should read that as the baseline, and ask what is being prepared and by whom.
Who Performs Sumakase IV Therapy at Seoulhoho Hospital
Dr. Ho-Sang Yoon, M.D.
Representative Director and Neurology Specialist
The clinic's description of the service is nevertheless explicitly physician-directed — the selection is made by the medical team from functional-medicine and neurological examinations. Its documented structure: Seoulhoho Hospital is headed by Dr. Ho-Sang Yoon, a board-certified neurologist and Representative Director who sees and assesses each patient personally. He graduated from Dongguk University College of Medicine, completed neurology specialist training at Dongguk University Hospital, and worked as a clinical professor at the Seoul National University Bundang Hospital Sleep/Epilepsy Center and at Dongguk University Ilsan Hospital.
The consultation is where the work is. It involves a detailed medical intake, evaluation of symptoms, lifestyle factors, vital signs, and risk factors such as kidney or heart health, in order to customise the infusion. Those two risk factors are not incidental: they are the reason a customised infusion needs a physician rather than a preference.
What a Session Involves
| Step | What happens |
|---|---|
| 1. Medical consultation and assessment | Detailed intake, symptoms, lifestyle, vital signs, kidney and heart risk factors |
| 2. Review of condition and needs | What the assessment shows about nutrient status |
| 3. Programme selection | The physician selects from over 50 available agents |
| 4. Administration | The infusion is given in the clinic |
| 5. Individual IV room | The patient remains in the private infusion and recovery area |
Step one is the step that distinguishes this from an off-the-shelf drip, and it is also the step a patient can most easily judge the service by. A detailed intake that asks about symptoms, lifestyle, vital signs, and kidney and heart risk factors takes time and produces a reason for the selection that follows. An intake that consists of choosing a name from a board does neither. If the assessment at step one is brief, the customisation at step three has nothing to work from, and the honest question to put to any clinic offering a physician-selected infusion is what the physician looked at before selecting.
Who Is a Good Candidate for Sumakase IV Therapy?
Individuals with severe chronic fatigue.
Individuals with assessed nutritional imbalances.
Individuals under immune system strain.
Individuals who require a highly personalised medical nutrient formulation.
Travellers managing severe jet lag or recovering from long international flights.
The exclusions are firm and specific, and they are the most important list on this page. Patients with end-stage renal disease, severe cardiac insufficiency, unmanaged electrolyte disorders, or known severe hypersensitivity to IV vitamins are not suitable candidates. Any of those four should be disclosed before an appointment is made, not at the chair, because each of them is a reason the answer is no rather than a factor to work around.
What to Expect: Procedure, Recovery, and Results Timeline
The consultation covers a detailed medical intake, symptoms, lifestyle factors, vital signs, and kidney and heart risk factors. The formulation is then selected, administered, and the patient stays in an individual IV room during treatment.
Preparation is simple and worth following: drink adequate water and eat a light meal before the visit, to keep blood pressure and blood sugar stable. Disclose your medical history, medications, supplements, allergies, and pregnancy status where relevant.
| Stage | Timing |
|---|---|
| Session length | Approximately 30–60 minutes |
| Visits | Completed in a single outpatient visit |
| Recovery | Immediate, with no downtime; normal daily activities resume afterwards |
| Hydration and energy effects | The clinic states these are often felt within hours |
| Duration of stated effects | The clinic describes them as persisting for several days to weeks |
Aftercare is specific: keep the catheter insertion site clean and dry, continue oral hydration through the day, and report any unusual swelling or pain. That last instruction is the one to act on rather than wait out, since swelling or pain at the site is how vein irritation and infection present.
The alternative the clinic names is oral vitamin supplementation, which it describes as having lower bioavailability and taking considerably longer to show effects than direct intravenous delivery. That comparison is the clinic's, and it is worth testing at the consultation against your own situation: where an oral route can achieve the goal, it avoids a needle and a vein, and the case for the intravenous route rests on something specific about the patient rather than on speed alone.
U.S. patients typically request this service to manage severe jet lag, to regain vitality after long international flights, and to receive a plan tailored to their current physical condition. Because it is a single outpatient session of under an hour, it fits a short trip more easily than the clinic's six-week autonomic programme — but the assessment that precedes it is what makes it a medical service rather than a convenience, and skipping it would remove the point.
Combining Sumakase IV Therapy with Other Services
Autonomic nervous system evaluation. Named by the clinic as a service this can be paired with, and available on site.
Chronic fatigue consultation. Named by the clinic among the pairings.
Skin rejuvenation programmes. Named by the clinic among the pairings.
3B IV therapy. The clinic's other named infusion service within the same programme.
Laboratory testing. Available through the clinic's internal medicine service where nutrient status needs measuring rather than estimating.
The most useful of those pairings is the last, and it is the one least often taken up. A nutrient deficiency is a measurable thing, and where laboratory testing can establish it, the selection at step three rests on a number rather than on an inference from symptoms. Where testing shows nothing lacking, that is also an answer, and a patient is entitled to have it before agreeing to an infusion aimed at replenishment.

Safety, Precision, and Clinic Standards
The minor risks the clinic lists are localised swelling or bruising at the puncture site, vein irritation, temporary dizziness, or mild flushing. Within the wider infusion programme, the documented risks also include infection or inflammation at the IV site, allergic or medication reactions, fluid overload, and changes in blood pressure or blood electrolyte levels depending on what is administered. The clinic's standing instruction across its infusion services is that the medical history and the ingredients used be reviewed with the treating physician before treatment.
The exclusion list is itself the main safety mechanism, and it is worth restating: end-stage renal disease, severe cardiac insufficiency, unmanaged electrolyte disorders, and known severe hypersensitivity to IV vitamins. Kidney and cardiac function determine whether a fluid and electrolyte load is tolerable, an unmanaged electrolyte disorder is the condition an infusion can most easily worsen, and a known hypersensitivity to IV vitamins is a contraindication rather than a caution. This is why the consultation assesses vital signs and kidney and heart risk factors rather than only asking what the patient wants.
Facilities are documented: individual infusion rooms and a recovery room, with four single-person rooms and three larger single-person rooms. Consultations are supported by AI real-time translation (smart glasses), which is assistive technology and not a professional medical interpreter service — worth confirming in advance for a treatment where ingredients, allergies, and consent all need to be communicated precisely. Seoulhoho Hospital is a registered medical institution in South Korea with business registration number 287-93-01985, and a Registered Medical Institution for Attracting Foreign Patients certified by the Ministry of Health and Welfare under the Medical Overseas Expansion and Foreign Patients Attraction Act.
On what this page will and will not say: the clinic describes the service as providing rehydration and the systemic delivery of micronutrients, and associates it with support for fatigue. Those are its stated purposes. The clinic states that claims about treating, preventing, or curing specific diseases, about boosting immunity, or about detoxifying the body should not be made without appropriate clinical evidence and service-specific approval — and no such evidence or approval is on record. This page therefore makes none of those claims, attaches no figure to any effect, and does not present the therapy as a treatment for any condition.
The Bottom Line
Sumakase is a physician-selected infusion rather than a fixed formulation, chosen from over 50 available agents.
Selection follows a detailed intake covering symptoms, lifestyle, vital signs, and kidney and heart risk factors.
A session runs roughly 30 to 60 minutes in a single outpatient visit, in a private IV room.
End-stage renal disease, severe cardiac insufficiency, unmanaged electrolyte disorders, and severe IV-vitamin hypersensitivity are exclusions.
No disease-treatment, immunity, or detox claim is made for it here.
Frequently Asked Questions
What does "doctor's choice" actually mean?
That the formulation is selected by the medical team rather than picked by the patient from a list. The selection draws on functional-medicine and neurological examinations and on a detailed intake, and the clinic has more than 50 agents available to combine. Ask what was selected and why — the reasoning is the service.
How long does it take?
Approximately 30 to 60 minutes, completed in a single outpatient visit. Recovery is immediate with no downtime, so normal daily activities can resume afterwards.
Does it hurt?
No general or local anaesthesia is needed for this therapy. What you feel is the cannula going in, and then nothing much: the clinic describes the procedure as involving only minor discomfort at that initial insertion. A dull ache or mild tenderness around the site during the infusion is possible and worth mentioning to staff if it becomes more than that.
How should I prepare?
Drink adequate water and eat a light meal before the visit, which helps keep blood pressure and blood sugar stable during the infusion. Bring a full list of medications and supplements, and disclose allergies and any pregnancy.
Who should not have it?
Patients with end-stage renal disease, severe cardiac insufficiency, unmanaged electrolyte disorders, or known severe hypersensitivity to IV vitamins. These are not cautions to be weighed against convenience — they are reasons the treatment is not appropriate.
Is it better than taking vitamins by mouth?
The clinic describes oral supplementation as having lower bioavailability and taking longer to show effects than intravenous delivery. Whether that difference matters for you is a clinical question rather than a general one, and it is the right thing to ask at the consultation before choosing the invasive route.
What do I do afterwards?
Keep the catheter insertion site clean and dry, keep drinking fluids through the day, and report any unusual swelling or pain. Do not wait on that last one — it is how site irritation and infection announce themselves.
How long do the effects last?
The clinic states that hydration and energy effects are often felt within hours and that it describes the overall effects as persisting for several days to weeks. Those are its descriptions rather than measured outcomes, and individual response varies.
