The recommended daily dose (RDA) for vitamin D3 varies depending on age and gender. Below is the current recommendations for taking vitamin D3 of the National Institutes of Health:
Infants (0-12 months): 400-1000 IE/day
Children (1-18 years): 600-1000 IE/day
Adults (19-70 years): 600-800 IE/day
Adults over 70 years: 800-1000 IE/day
It is important to note that these are general guidelines and may not be suitable for everyone. Some people may need higher doses of Vitamin D3to get optimal health, especially people with certain health problems or limited sunlight.
In addition to age and gender, other factors that can influence the vitamin D3 requirement can be the geographical location, skin pigmentation and general health. People who live in northern widths or people with darker skin may need more vitamin D3 than people who live in southern widths or people with brighter skin.
It is also important to note that an excessive supply of Vitamin D3 can be harmful. The safe upper limit for the inclusion of vitamin D3 is 4,000 IE/day for adults, although some experts recommend up to 10,000 IE/day for certain people with vitamin D3 deficiency under the guidance of a health service provider.
In summary, it can be said that the recommended Vitamin D3 dosing for optimal health depending on age, gender and individual factors varies. It is important to speak to your doctor in order to determine the appropriate dosage for your individual needs and ensure that you do not exceed the safe upper limit. A sufficient supply of vitamin D3 is crucial for maintaining optimal health. Therefore, make sure that you eat sufficient vitamin D3 through nutrition, sunlight and/or dietary supplements.
