Germany raised Vitamin D RDA to 800 IU - helped infants, but not children (who need even more) – June 2019

Having a good level of vitamin D cuts in half the amount of:

Need even more IUs of vitamin D to get a good level if;

  • Have little vitamin D: premie, twin, mother did not get much sun access
  • Get little vitamin D: dark skin, little access to sun
  • Vitamin D is consumed faster than normal due to sickness
  • Older (need at least 100 IU/kilogram, far more if obese)
  • Not get any vitamin D from formula (breast fed) or (fortified) milk
    Note – formula does not even provide 400 IU of vitamin D daily

Infants-Children need Vitamin D

At least the German levels did not crash as they did in Poland

800 IU only help those with low weight

Note: 20 lbs at age 1 ==> 105 lbs at age 14: 5X more vitamin D is probably needed for teens - and even more if obese, etc.
Clipped from PDF "German guidelines recommend vitamin D only for the first 12–18 months of life"
  So, many German mothers probably did not give much or any vitamin D if > 2 years old

Purpose: Vitamin D is a key component for the growth and development of children and adolescents, influencing a multitude of functions. Worldwide epidemiological studies have shown that minimum vitamin D blood levels of ≥ 20.0 ng/ml, often defined as vitamin D sufficiency by international and national nutrition and pediatric organizations, are often not met in practice. In 2012 the D-A-CH (Germany, Austria, Switzerland) nutrition societies increased their vitamin D intake recommendations fourfold from 200 IU (5 µg) to 800 IU (20 µg) per day. The outcome of this study will contribute to answering the question as to whether the new recommendations for increased vitamin D intake improve the highly prevalent vitamin D deficiency status in German children and adolescents.

Methods: For this 6-year study (January 2009-December 2014) carried out in Mülheim an der Ruhr, Germany, healthy children and adolescents (n = 1929, age range 1-17 years, median age 11.0 years, 46.9% female) consulting a pediatric group practice (KIDS4.0) were recruited. Serum 25(OH)D determinations were performed using a competitive chemoluminescence immunoassay (CLIA, DiaSorin).

Results: The median serum vitamin D values for each year from 2009 to 2014 were 18.4, 13.0, 20.8, 16.4, 19.4 and 14.9 ng/ml. The summarized median 25(OH)D serum concentrations between the two time periods 2009-2012 and 2013-2014 after increasing recommendations for vitamin D intake did not show a significant difference (17.0 versus 16.8 ng/ml).

Conclusions: The increased D-A-CH recommendations for vitamin D intake had no influence on vitamin D levels in children and adolescents. The prevalence of vitamin D deficiency has not changed compared to previous studies.
