A new review from Germany reports that of almost 200 population-based studies worldwide more than 37% report that inadequate blood vitamin D levels are wide-spread.
The systematic review analyzed data on vitamin D supply from more than 168,000 people across 195 studies conducted in 44 countries (1). The analysis showed that 37.3% of the studies reviewed reported mean serum vitamin levels, measured by 25-hydroxyvitamin D values, to be below 50 nmol/L, a value considered inade-quate by health authorities worldwide. The vitamin D values were higher in North America than in Europe or the Middle-East. Age-related differences were observed for the Asia-Pacific and Middle East regions, but not elsewhere. Sex-related differences were not observed in any region.
The researchers commented that although vitamin D deficiency is associated with osteoporosis and is thought to increase the risk of cancer and cardiovascular disease, data on vitamin D status at the population level and within key subgroups are limited. The substantial heterogeneity between the reviewed studies within each region precludes drawing conclusions on overall vitamin D status at the population level.

Marine omega-3 fatty acids are important for the developing brain, adult brain health and protection against cognitive decline in the elderly. DHA is an important structural part of the nervous tissue whilst circulating EPA levels appear to be important in prevention of the onset of depression. This review will examine the current evidence with regard to efficacy.
