Garlic IV (Fursultiamine) in Gangnam, Seoul

Medically reviewed by Dr. Kim Yoo Suk, MD · Board-certified otolaryngologist · Former professor, Yonsei & Ajou University · Consultations in English

What is a garlic IV?

A garlic IV, known in Korea as "maneul jusa," is an intravenous infusion whose main ingredient is fursultiamine, a synthetic derivative of thiamine (vitamin B1). Thiamine is a water-soluble vitamin that the body uses as a cofactor in energy metabolism, helping convert carbohydrates into usable energy. Fursultiamine was developed from allithiamine, a compound first identified in garlic, and it gives off a characteristic garlic-like smell or taste during infusion. The drip contains no actual garlic.

A balanced perspective

Thiamine deficiency is uncommon in people with a varied diet. A garlic IV is a wellness option some adults choose; it is not a treatment for fatigue of unknown cause, and it should not delay evaluation of persistent tiredness, which can stem from sleep disorders, anemia, thyroid problems or other conditions.

Who might consider it?

Some adults choose a garlic IV during periods of high workload or travel. Persistent fatigue deserves proper investigation. For example, poor sleep from sleep apnea or chronic nasal congestion is a treatable cause of daytime tiredness that an ENT can evaluate. A garlic IV is generally avoided in people with thiamine allergy and used cautiously in certain medical conditions.

How it is done at our Gangnam clinic

Dr. Kim Yoo Suk is a board-certified otolaryngologist and a former professor at Yonsei and Ajou universities. In line with the clinic's principle of recommending only what a patient needs, IV therapy is never pushed, and excessive or repeated drips are not recommended.

1. Consultation: a review of your health, medications, allergies and reasons for considering an IV.
2. Private single-room suite: you rest comfortably in your own room during the infusion.
3. Safety: single-use consumables and strict infection-control procedures.
4. Duration: a session typically takes about 30 minutes.

Nutrition IVs are non-covered (non-insured) items; fees are explained beforehand. Parking for IV-therapy patients is covered by the clinic.

After your session

You can generally return to normal activities right away. A garlic-like taste may linger briefly. Keep the IV site clean, and contact the clinic if redness or swelling develops.

Risks and limitations

Possible side effects include discomfort, bruising or vein irritation at the IV site, a warm sensation, and rarely allergic reactions. No IV vitamin should be considered a substitute for a balanced diet, adequate sleep and medical evaluation of ongoing symptoms. Tell the staff if you are pregnant or breastfeeding, or have kidney, heart or liver disease.

Practical information for foreign patients

Frequently asked questions

Does a garlic IV actually contain garlic?

No. The main ingredient is fursultiamine, a vitamin B1 derivative originally developed from a compound found in garlic. It produces a garlic-like smell or taste during infusion, which is how the drip got its popular name.

Will a garlic IV cure my fatigue?

A garlic IV is not a cure for fatigue. Persistent tiredness has many possible causes, including poor sleep, anemia, thyroid problems and sleep apnea, which deserve proper evaluation. Dr. Kim can help identify ENT-related causes such as nasal obstruction.

Is a garlic IV covered by insurance?

Nutrition IVs are non-covered items under Korean national health insurance at our clinic. Fees are explained before treatment. Receipts are available, though private insurers generally do not cover wellness IVs.
