In parallel with the questionnaires for general consumers so far, we conducted individual questionnaires about vitamin C for doctors, and summarized the questionnaire results of 100 doctors who responded.
The survey of 100 doctors was the first attempt by our company, Spick Co., Ltd., and it was very valuable data.
 
[Summary of this questionnaire survey]
・More than half of the doctors answered that their daily vitamin C intake was "2,000 mg or more," while half of the general consumers answered "less than 1,000 mg," more than double the amount.
・95% of the doctors answered that they know that the absorption rate of vitamin C varies depending on the method of intake, and more than half of the general consumers answered that they do not know.
・Vitamin C ingestion methods recommended by doctors are "intravenous vitamin C at medical institutions" and "vitamin C preparations prescribed by medical institutions". However, less than 5% of general consumers use them.
There was a large gap between the responses of doctors and the general public.
Each item is explained below.
 

The required daily intake of vitamin C according to the doctor's answer.
More than half of doctors recommend "2,000 mg or more". Half of general consumers answered “less than 1,000mg”.

 
In a questionnaire, 100 doctors were asked to answer the numerical value of "the required daily intake of vitamin C", and more than half answered "2,000 mg or more". On the other hand, when the same question was asked to general consumers, about half of the respondents answered "less than 1,000 mg", a contrasting result with doctors. (See diagram below)

Regarding the "required daily intake of vitamin C", the average value of the general answer was "919mg", while the average value of the doctor's answer was "2,081mg*". On average, physicians reported daily vitamin C requirements more than twice as high as the general public.
* Calculated excluding the response “the more the better”
Most doctors answered that "the absorption rate differs depending on the intake method of vitamin C."
On the other hand, the result is less than half of general consumers.
When asked, "Do you know that the absorption rate differs depending on how you take vitamin C?", 95% of doctors answered, "I know."
On the other hand, less than 40% of the respondents answered “I know” to the same question in the general questionnaire.
The results showed that 60% of people who take vitamin C on a regular basis do not know that the absorption rate differs depending on the method of intake. difference became apparent.

About the effective intake method. Nearly 90% of doctors recognize the effectiveness of "(vitamin C) drip prescribed by medical institutions," but only 1.8% of general consumers use it.

to the doctor, vitamin C "What is the best way to take it?" Regarding, when the assumed intake method was evaluated in 5 stages, Nearly 90% of respondents answered that “(vitamin C) drip prescribed by a medical institution” is “very effective” or “somewhat effective”. Next, about 80% support "oral vitamin C prescribed at medical institutions" As a result, in this survey, the above two intake methods were more popular than "from regular meals".

On the other hand, in the general questionnaire, "How do you usually take vitamin C?" This was followed by ``with supplements and health foods'' and ``with beverages such as fruit juices and vegetable juices'', followed by ``intravenous drips prescribed by medical institutions'' and ``oral vitamin C prescribed by medical institutions'' supported by questionnaires for doctors. ” was hardly answered in the general survey, at 1.8% and 4.6%, respectively.

A comparison of the two surveys revealed that people who take vitamin C on a regular basis tend to take it through relatively easy methods such as diet, supplements, and juices. , supports intake methods that are considered to be highly effective and provided at a medical level, such as "intravenous (vitamin C) prescribed by medical institutions" and "oral vitamin C preparations prescribed by medical institutions." It turns out that the “method of intake recommended by doctors” is rarely selected among general consumers.
 

Problems with vitamin C intake. 'Double gap' in physicians' and public perceptions of vitamin C requirements. Only "less than 5%" use the intake method recommended by doctors. Breakthroughs to overcome challenges.

This time, as a result of comparing the data obtained from the physician survey and the general survey, half of the doctors said that the amount that doctors think they need is "more than twice" the amount that general consumers think is necessary, which is significantly higher than the general perception. It turned out to have a high capacity.
In addition, doctors supported ``vitamin C intake methods provided at the medical level (prescribed intravenous drip, vitamin C preparations)'' as ``effective.''
On the other hand, general consumers tend to consume it only as an extension of their daily diet, and only less than 5% of general consumers actually practice the methods that doctors consider effective. has also become clear.
From the above results, This reveals the issue of intake in that most people are unable to utilize methods that are presumed to be highly effective from a medical perspective.
``While general consumers seek convenience, doctors emphasize effectiveness'' is likely to be common not only to vitamin C but also to other supplements and treatments, and is a trend that is reflected in Japan's medical and health care industry. When considering the future of care culture, it is necessary to always be aware of this difference in attitude.
It seems that there is.
In order to close this gap and enable more effective vitamin C intake in the future, we need to create an environment that allows easy access to "medical-grade" intake methods and develop highly efficient supplements with higher absorption rates. There may be a need for some new breakthrough in vitamin C intake.
