How much vitamin C is... good for the immune system?

We all know that the body’s immune system is important in helping us stay healthy and resist illness. However, many people may not know that “Vitamin C” is an essential vitamin that plays a role in strengthening the immune system because it stimulates the effective functioning of white blood cells. Today, Phyathai 3 Hospital would like to share some useful knowledge about vitamin C, including guidelines on how to take it to maximize the body’s immune strength.

How much vitamin C does the body need daily to have a strong immune system?

To enhance the body’s immune system to fight against pathogens during an outbreak, the body requires 1,000 – 3,000 milligrams of vitamin C per day. A secret that many people may not know is that research on vitamin C absorption in the human body indicates that the body can absorb only about 200-400 milligrams of vitamin C per dose. This means that even if we take 1,000 milligrams of vitamin C, the body will only absorb about 400 milligrams at a time. Therefore, the most appropriate and effective way to take vitamin C is to divide the intake into 500 milligram doses, 2-6 times a day, so the body receives a sufficient amount of vitamin C to strengthen the immune system effectively.

Additionally, an important precaution when taking vitamin C is to drink plenty of water afterward, at least 1-2 glasses, to avoid the risk of precipitation that could lead to kidney stones. Therefore, the safest approach is to take vitamin C during the day and avoid taking it before bedtime, as we may not drink enough water then. For those with digestive system issues, excessive vitamin C intake may cause irritation, such as stomach burning or diarrhea.

What is Vitamin C Drip and how is it different from oral intake?

Besides taking vitamin C in tablet form, we can also introduce vitamin C into the body to boost immunity through Drip, or intravenous administration, similar to saline drip therapy. The advantage of vitamin C Drip compared to oral intake is that it delivers a high concentration of vitamin C to the body at once, allowing full absorption. This differs from oral intake, which only absorbs about 200-400 milligrams per dose. It is easy, convenient, not complicated, and takes only 1-2 hours without needing multiple doses per day. Moreover, vitamin C Drip is usually done as a program called Immune Booster, which intensively strengthens the immune system and includes other essential vitamins and amino acids, resulting in better immune enhancement than oral intake.

Are there any precautions for Vitamin C Drip?

When undergoing Vitamin C Drip or the Immune Booster program to strengthen the immune system, since it involves administering a high concentration of vitamins, there are some precautions in certain cases, including:

• Kidney patients: Doctors must evaluate kidney function first to ensure it is normal because high kidney values may affect the elimination of excess vitamin C from the body.
• Patients with G6PD deficiency: This condition involves a deficiency of the G6PD enzyme, and receiving high concentrations of vitamin C may cause red blood cells to break down.
• Those with a history of vitamin C allergy: Doctors will take a history and inquire about symptoms first. If an allergy to vitamin C is found, the intensive vitamin C Drip program will not be recommended.
• Children: It may not be necessary for children to receive high-concentration vitamin C Drip to boost immunity because their bodies are still growing and strong. Continuous supplementation in appropriate amounts is sufficient.

Vitamin C plays a very important role in strengthening the body’s immune system, leading to overall good health. We can choose how to increase vitamin C in the body, either by oral intake or by Drip through the veins, each with its pros and cons. If you want to avoid needles, oral intake is an option, but it requires multiple doses daily and continuous long-term use before the immune system improves. However, if you want to quickly and effectively boost your immune system, vitamin C Drip through the Immune Booster program is more suitable because a single session provides other beneficial vitamins besides vitamin C, helping the body develop a highly effective immune system rapidly. This is especially appropriate in the current situation of disease outbreaks and pollution.
