Is 'Nutritional Deficiency' the Reason You Can't Sleep? Granpro Sleep Beauty Clinic Launches 'Sleep x Nutrition Test'

Granpro Sleep Beauty Clinic (Chuo-ku, Tokyo; Director and President: Norika Hirose; hereinafter 'the Clinic'), produced by Prolab Holdings Co., Ltd. (Headquarters: Minato-ku, Tokyo; Representative Director and CEO: Hiroyuki Sasaki; hereinafter 'the Company'), will launch a new testing program, 'Sleep x Nutrition Test,' on Monday, May 11th. This program combines nutritional testing with testing for the sleep hormone 'melatonin.'

Since its opening in May 2025, the Clinic has been providing counseling and treatment to patients of various ages suffering from sleep problems.

Based on past interviews and clinical experience, and considering the possibility that individual nutritional status and the sleep hormone 'melatonin' may be related to sleep quality, the Clinic will introduce the 'Sleep x Nutrition Test' program. This program combines nutritional analysis and melatonin testing to gain a more comprehensive understanding of sleep conditions.

Proposing a Drug-Free Approach Amid Rising Sleep Concerns

In recent years, there has been an increase in people suffering from sleep problems such as 'can't sleep,' 'waking up multiple times at night,' and 'still tired after sleeping.' However, there are still not many medical institutions specializing in sleep, and even when patients visit a medical institution, treatment often focuses on medication, with fundamental causes often not being addressed.

In response to this situation, the Clinic has been offering treatment approaches centered on 'sleep improvement therapy' since its opening. This is for individuals who struggle with sleep but do not require 'sleeping pills' or 'CPAP' (used for sleep apnea treatment), and for those who wish to improve their sleep quality with as little reliance on medication as possible.

Furthermore, through interviews with patients who visited not only for sleep problems but also for beauty and health purposes, it has become clear that various factors such as stress, lack of exercise, and body coldness are related to the inability to sleep. In addition, hormone and nutrition tests on some patients revealed cases of nutrient deficiencies related to sleep quality. Cases where changes in sleep status were observed through an approach combining nutritional guidance, vitamin IV drips, and supplements have also been confirmed.

Based on these results, the Clinic will launch the 'Sleep x Nutrition Test' on Monday, May 11th, as a new initiative based on the concept of molecular integrative nutrition. This initiative aims to 'unravel the reasons for sleeplessness from blood tests and provide treatment according to the results.'

Sleep Disturbances Are Not Just a Problem of 'Stress' or the 'Brain'

The Clinic views sleep not merely as a psychological issue but as something influenced by the interaction of hormones, nutritional status, and the autonomic nervous system.

The following factors may be related to the inability to sleep:

・Decreased melatonin secretion

・Vitamin D deficiency

・Iron (ferritin) deficiency

・Vitamin B group deficiency

・Magnesium deficiency

These factors are often not adequately evaluated in general medical practice, and it is not uncommon for them to be treated as 'insomnia of unknown cause.'

What is the 'Sleep x Nutrition Test'?

This test comprehensively evaluates the following indicators through blood and saliva tests:

・Melatonin-related indicators ・Vitamin D

・Ferritin (iron storage) ・Vitamin B12 ・Magnesium ・Zinc ・Blood sugar-related indicators

Based on these test results, doctors provide counseling and propose a 'sleep design' tailored to each individual's condition, including nutritional guidance, IV drip therapy, supplement planning, and lifestyle advice.

Future Outlook

In the future, the Clinic plans to aggregate anonymous data from visitors and disseminate information as a 'Nutritional Tendency Report for People with Sleep Problems.' The goal is to provide sleep medicine based on science and data, rather than viewing sleep solely as a 'mental theory.' The Clinic will continue to work on the development of 'sleep beauty medicine' that connects sleep with beauty and health.
