This fall, Lypo-C will introduce a new product called "Vitamin C + D." Like Lypo-C VitaminC, it contains vitamin C in a capsule made of phospholipid, and vitamin D3 in a double membrane.

Vitamin C has been featured frequently in Lypo-C Magazine. But what about vitamin D?
We asked Dr. Yoshinori Nagumo, director of Nagumo Clinic, about the basic information about vitamin D: what it does, what happens if it's deficient, and how to take it.

What kind of nutrient is vitamin D?

The generally known role of vitamin D is to support the function of calcium and maintain the health of the body. In addition, it has long been said that exposure to sunlight in the summer makes it harder to catch a cold in the winter, and the stored vitamin D stored during the summer protects the body's health in the winter. . In addition, in recent years, it has been reported that in addition to regulating the body's condition, it is also useful in countering lifestyle habits.

Is the sun the key to how vitamin D is produced?

When sebum on the surface of the skin is exposed to ultraviolet rays, it converts into vitamin D. For this reason, vitamin D is also called the "sunshine vitamin."
It is also possible to get vitamin D from food. Foods that contain vitamin D include fish, meat, eggs, and mushrooms. In particular, it is found in fish such as blue-green fish, which are exposed to plenty of UV rays, and mushrooms, such as dried shiitake mushrooms that are dried in the sun.

How much vitamin D should I take in a day?

It is said that adults should take 2,000 IU (50 ml) a day, but for people who are prone to deficiency, this may not be enough and ideally they should take 4,000 IU (100 ml). Recently, there has been an increase in the number of middle-aged and elderly people suffering from vitamin D deficiency, so if you are diagnosed, you may be advised to take more.
By the way, as mentioned above, it is possible to get vitamin D from food, but the amount absorbed is minimal. Also, vegetables do not contain vitamin D, so it is difficult to get it from food.
Ideally, you should get plenty of sunlight and supplement it with supplements.
Before exposing your skin to UV rays, such as swimming in the sea, it is a good idea to pre-bake it by using a UV ray machine or sunbathing on the veranda or balcony.

Are 98% of Japanese people deficient in vitamin D?

By the way, according to a recent study by Tokyo Jikei Medical University, 98% of the 5,500 average adult men and women are deficient in vitamin D. Even in the health-conscious population, 87% of people are vitamin D deficient. In other words, most people today tend to be vitamin D deficient.

Sunbathing has been well-established as a health method for people since the days when medical care was not widespread, but ever since the ozone hole was reported by a Japan Meteorological Agency official exploring Antarctica in 1985, a skin whitening boom has arrived.
Japanese people are now said to be the most sunlight-shy people in the world, and as a result, most Japanese people are deficient in vitamin D.

The advantage of being made into liposomes is the absorption rate.

First, the rate of absorption into the body is different. By forming liposomes, vitamins are absorbed from the intestinal tract and sent throughout the body through systemic circulation, making it easier for them to reach their target cells and enter the cells. Therefore, it is easy to experience vitamin C and D, and you can expect sustainability.
Also, vitamin C is unstable and easily oxidized and broken down, so you have to wait a while before taking it, but since it is in liposome form, the quality is stable and you can take a lot at once.

summary

It turns out that vitamin D, like vitamin C, is an essential nutrient for maintaining our health. From now on, let's be conscious of vitamin D as well as vitamin C. First of all, sunbathe and be conscious of eating foods containing vitamin D. Furthermore, you can replenish it more efficiently by absorbing it with liposomal supplements.
