We’ve written about the importance of Vitamin D as it relates to health and the body’s ability to ward off illness in previous Babyminding articles. Vitamin D deficiency is common in people of all ages. The sun is the best source of Vitamin D. However due to skin cancer concerns and the subsequent application of sunscreen, the body’s ability to produce Vitamin D is reduced by as much as 95%. As a result of this reduced exposure to the sun, it is necessary to supplement with Vitamin D3 (cholecalciferol) in order to keep serum d blood levels of the body above 30 ng/mL.
Over the past year the amount of recommended supplementation has increased from 400 to 800 IU for adults and from 200 to 400 IU for children. New guidelines just released from a study published in the Journal of Clinical Endocrinology and Metabolism, offer additional guidelines that increase the recommended dosage of Vitamin D supplementation to maintain optimal health. The new guidelines recommend different doses of vitamin D for those at risk of vitamin D deficiency as follows (all listed in International Units (IU) daily):
- Age 0 to 1 year: 400 to 1,000
- Age 1 to 18 years: 600 to 1,000
- All adults over age 18: 1,500 to 2,000
- Pregnant or nursing women under age 18: 600 to 1,000
- Pregnant or nursing women over age 18: 1,500 to 2,000
- Because fat stores vitamin D, obese people may need to take two or three times the usual dose of vitamin D.
