A lack of vitamin D in the body was found to increase the risk of dementia by 54%.
The research team led by Professor Elina Hipponen, director of the Precision Health Center at the University of South Australia, published the results of this research in the international journal ‘American Journal of Clinical Nutrition’ in June 2022.
The research team analyzed the UK Biobank genetic analysis data of 294,514 people. As a result, the lower the blood level of vitamin D, the higher the risk of dementia. % was reported to be high.
Vitamin D deficiency is diagnosed when blood levels are less than 50 nmol/L (20 ng/mL). According to the national health and nutrition survey in Korea, the vitamin D concentration was 18-19ng/mL, and an average of 90% was found to be deficient.
Vitamin D can be synthesized in the body through the skin exposed to the sun’s ultraviolet rays, but modern people spend a lot of time indoors and when outdoors, it is difficult to produce enough vitamin D naturally by applying sunscreen. Therefore, it is recommended to supplement a certain amount of vitamin D daily through intake of eggs, milk, fish, etc. or through vitamin D supplements.
However, in order to take vitamin D safely, products using organic vitamin D are recommended. When vitamin D is derived from dry yeast, pesticides and chemical fertilizers may be used during cultivation and processing, but these are not 100% completely removed, so chemical components remain in the raw material. If chemicals such as pesticides accumulate in the body, they can be fatal to health, so you must avoid them.
Organic vitamin D can be easily identified by checking whether there is an organic processed food certification on the product package. At this time, organic vitamin D with the ‘WCS’ sign is more reliable in quality. WCS is an abbreviation of ‘Warrant Contents Standard’, which strictly checks the safety, content, and authenticity of raw materials. Therefore, if there is organic processed food certification and WCS mark, you can trust and consume it.
In addition, if you want to purchase a vitamin D supplement that does not use chemical ingredients in the manufacturing process, you should look for a ‘Nochestem’ or ‘NOCHESTEM’ sign. This mark is regarded as a mark that can confirm safety as it has the meaning of guaranteeing quality by not using any chemical components in the manufacturing process.
