High-dose Vitamin C IV Drip therapy is a treatment method that directly injects vitamin C into the bloodstream in quantities that cannot be fully obtained through regular diet or supplements.
This method allows vitamin C to be efficiently absorbed into the body, offering various health benefits. It is known for its strong antioxidant properties, boosting immunity, aiding fatigue recovery, and providing skin whitening and beautifying effects. Additionally, some studies suggest its potential as an adjunct therapy in cancer treatment.
The required blood concentration of vitamin C varies with age. Since cells can only hold a limited amount of vitamin C, any excess above a certain concentration is excreted from the body. Therefore, regular administration is recommended to maintain optimal blood levels of vitamin C.


The high-concentration vitamin C solution used at our clinic is manufactured in Korea and contains absolutely no preservatives. ※Due to the discontinuation of Japanese manufacturing starting May 2025, we have switched to the Korean-made product. Existing course participants will continue to receive the Japanese-made solution.
You may also choose your vitamin dosage from 12.5g or 25g.
For first-time high-concentration vitamin C recipients requesting the 25g dose, we require a G6PD test. This simple test ensures your treatment is safe. Results will be available later, so treatment cannot be performed on the same day. (Those who have already undergone testing elsewhere with no issues do not need to be tested again).
High-concentration vitamin C IV therapy delivers 12.5g or more of vitamin C intravenously to achieve greater efficacy.
From approximately 12.5g to 50g, the antioxidant effect is strong. At 50g or more, the oxidation effect of vitamin C is said to provide an anti-cancer effect.
| 12.5g (equivalent to 625 lemons) | Antioxidant effects, skin beautification |
|---|---|
| 25g (equivalent to 1,250 lemons) | Antioxidant effects, skin beautification, immune system enhancement |
| 25g and up | Cancer prevention effects |
Neutralizes free radicals and prevents cellular damage.
Strengthens immunity against colds and infections.
Boosts energy levels and reduces feelings of fatigue.
Promotes collagen production, improves skin firmness, suppresses melanin, and enhances skin translucency.
Some studies suggest high-dose vitamin C may inhibit cancer cell proliferation.
The recommended daily intake of Vitamin C is approximately 90mg for adult men and 75mg for adult women.
According to the Ministry of Health, Labour and Welfare’s “Dietary Reference Intakes for Japanese (2020 Edition)”, the recommended daily intake of vitamin C for adults is 100mg for both men and women. To achieve its antioxidant effects, an amount equivalent to the recommended intake is considered necessary.
In recent years, vitamin C intake has been insufficient across most age groups due to reduced vegetable consumption and factors like smoking and stress. Therefore, conscious intake of vitamin C is necessary.
Foods rich in vitamin C include:
| Food | Content |
|---|---|
| Acerola | 1667mg |
| Red Bell Pepper | 190mg |
| Broccoli | 89.2mg |
| Orange | 53.2mg |
| Lemon | 50mg |
| Cabbage | 47mg |
For daily vitamin C supplementation, oral supplements are effective. However, when consuming 1,000–2,000mg (the tolerable upper intake level) via supplements or nutritional drinks, absorption rates drop to below 20%.
High concentrations deliver results
For beauty goals, potent antioxidant effects, immune system support, or fatigue recovery, vitamin C IV drips are highly effective.
To achieve the desired effects from vitamin C IV drips, a typical recommended dose ranges from 12.5g to 50g per session. This amount is significantly higher than oral intake, allowing vitamin C to be efficiently distributed throughout the body.
| Food | Oral Supplements | IV Infusion |
|---|---|---|
| Absorption Pathway | 1 Absorbed through the intestines | Directly injected into the bloodstream |
| Absorption Rate | Limited (Part of intake is excreted) | 1 High concentrations can be absorbed into the body |
| Convenience | Simple, inexpensive | Requires treatment at specialized facilities |
| Immediate Effect | Gradual | Immediate effect |
| Effects | Ideal for daily vitamin supplementation | Skin beautification, immune system enhancement, antioxidant effects, etc. |
For first-time patients, a consultation allows you to discuss treatment goals and expected outcomes with the physician. The dosage of high-concentration vitamin C will be determined based on the physician’s examination and your preferences.
This is performed safely by a specialist physician at the medical facility. A relaxing environment is provided during the IV drip. The duration varies by individual but typically takes about 30 to 40 minutes.
If you have any concerns after treatment, please feel free to contact us anytime. We will adjust your treatment plan as needed to help you maintain optimal health.
