In 11 years
% of Fins supplementing: 11 % ==> 41 %
Vitamin D levels: 19 ng ==> 26 ng
Strange: very little variance reported in the measured range: 95% apparently within 1 nmol of the mean
Total population nmol
| 2000 | 2011 | |
| <30 | 13.0 % | 0.6 % |
| 30-40 | 32.0 % | 3.2 % |
| 40-50 | 55.7 % | 9.1% |
| 75-125 | 4.1% | 19.9% |
| >125 | 0 % | 8% |

Very strange that % do not total to 100%

- 4 times fewer with vitamin D deficiency in just 4 years ( Connecticut) – March 2016
- Vitamin D levels increasing 7 percent per year, bones denser in Japan (probably supplementation) - June 2015
- Vitamin D supplementation in Ireland - big increase in people with 20-50 nanograms in 20 years – June 2015
Background: A systematic vitamin D fortification of fluid milk products and fat spreads was started in 2003 in Finland to improve vitamin D status.
Objective: We investigated the effects of the vitamin D fortification policy on vitamin D status in Finland between 2000 and 2011.
Design: Serum 25-hydroxyvitamin D [S-25(OH)D] concentrations of a nationally representative sample comprising 6134 and 4051 adults aged ≥30 y from the Health 2000 and Health 2011 surveys, respectively, were standardized according to the Vitamin D Standardization Program with the use of liquid chromatography-tandem mass spectrometry. Linear and logistic regression models were used to assess the change in S-25(OH)D concentrations.
Results: Between 2000 and 2011, the mean S-25(OH)D increased from 48 nmol/L (95% CI: 47, 48 nmol/L) to 65 nmol/L (95% CI: 65, 66 nmol/L) (P < 0.001). The prevalence of vitamin D supplement users increased from 11% to 41% (P < 0.001). When analyzing the effect of fortification of fluid milk products, we focused on supplement nonusers. The mean increase in S-25(OH)D in daily fluid milk consumers (n = 1017) among supplement nonusers was 20 nmol/L (95% CI: 19, 21 nmol/L), which was 6 nmol/L higher than nonconsumers (n = 229) (14 nmol/L; 95% CI: 12, 16 nmol/L) (P < 0.001). In total, 91% of nonusers who consumed fluid milk products, fat spreads, and fish based on Finnish nutrition recommendations reached S-25(OH)D concentrations >50 nmol/L in 2011.
Conclusions: The vitamin D status of the Finnish adult population has improved considerably during the time period studied. The increase is mainly explained by food fortification, especially of fluid milk products, and augmented vitamin D supplement use. Other factors, such as the difference in the ultraviolet radiation index between 2000 and 2011, may partly explain the results. When consuming vitamin D sources based on the nutritional recommendations, vitamin D status is sufficient [S-25(OH)D ≥50 nmol/L], and supplementation is generally not needed.
