TABLE 3. Summary of findings of different surveys (including all category groups)

Places where the
studies were implemented
All of these studies except one in Romania and another in Mongolia were conducted in developed countries. Most of these countries were located in high latitude regions (30°N or higher). Seasonal variation was obvious for vitamin D deficiency, and most studies were conducted during winter.
Food vehicles used The common food carriers for vitamin D fortification included milk, cheese, and other dairy products (both regular-fat and low-fat); margarine; oil spread; orange juice; and bread.
Fortification levels The fortification level of these studies varied from 2.5 to 125 µg /day; the most common doses were between 5 and 25 µg/day (1 to 5 times AI). The fortification level for each food depended on the intake and characteristics of that food (e.g., 0.5 µg/100 mL for milk and 10 µg/100 g for margarine in Finland).
Impacts of the studies
on 25OHD concentration
20 studies showed beneficial effects of vitamin D fortification on 25OHD concentration or vitamin D deficiency. The magnitude of mean 25OHD concentration improvement varied from 2 to 97.1 nmol/L; the most common improvements were between 9.9 and 34.5 nmol/L. The magnitude was significantly related to the fortification level used (n = 8, r = 0.98, p < .01), which is also supported by the meta-analysis of Black et al. [19]. For example, fortification with the lowest (2.5 µg/day) and the highest (125 µg/day) amounts of vitamin D resulted in the smallest (2 nmol/L) and the largest (97.1 nmol/L) improvements in 25OHD, respectively.
Impact of the studies
on other markers
Vitamin D fortification suppressed PTH in 8 of 14 studies. When products fortified with both vitamin D and calcium were consumed, BMD increased in various locations, including hip, femoral neck, ultradistal radius, spine, and pelvis. However, it is difficult to attribute the benefits to vitamin D or calcium alone, due to the design of these studies.
Toxicity No adverse effects were reported when food fortified with 100 µg/day vitamin D was consumed for 2 months. Serum calcium concentration, a biomarker for vitamin D toxicity, did not increase during 1 year of intervention with 125 µg/day vitamin D, although urinary calcium concentration increased at 3, 6, and 9 months, but not at 12 months. When 25 µg/day vitamin D or less was consumed, some subjects reported gastrointestinal discomfort.
