"One thing that complicates trials is that if you give someone vitamin D, it takes a long time for it to have much effect, as vitamin D levels go up and down very slowly; it probably wouldn't be a fast antidepressant," said Dr. Brown.
Dette er et sitat jeg merker meg. Det tar altså lang tid før D3 nivåene går opp, og før de gir en effekt i kroppen. Hvis du har lest om D3 tidligere, vet du at D3 har mange effekter på forskjellige deler av kroppen.
Sitat:
In the overall sample, higher vitamin D levels were associated with a decreased risk for current depression, based on CES-D scores. The odds ratio [OR] was 0.92 (95% confidence interval [CI], 0.87 - 0.97; P < .002) for each 10 ng/mL increase in 25(OH)D.
When study participants with and without a history of depression were analyzed separately, the link was stronger in those with a prior history of depression (OR, 0.90; 95% CI, 0.82 - 0.98; P = .02) and was not significant in those without such a history (OR, 0.95; 95% CI, 0.89 - 1.02; P = .17).
It is biologically plausible that vitamin D could have a role in depression, Dr. Brown and colleagues note in their article. Vitamin D "appears to be important for brain health and may be involved in the pathogenesis of depression." Yet, studies to date have yielded conflicting results.
