Vitamin D vs broad spectrum phototherapy in the treatment of seasonal affective disorder. Gloth FM 3rd, Alam W, Hollis B. J Nutr Health Aging. 1999;3(1):5-7. PMID: 10888476 All subjects receiving vitamin D improved in all outcome measures. The phototherapy group showed no significant change in depression scale measures. Vitamin D status improved in both groups (74% vitamin D group, p < 0.005 and 36% phototherapy group, p < 0.01). Improvement in 25-OH D was significantly associated with improvement in depression scale scores (r2=0.26; p=0.05). Vitamin D may be an important treatment for SAD. Further studies will be necessary to confirm these findings..

Randomized comparison of the effects of the vitamin D3 adequate intake versus 100 mcg (... - 0 views

Randomized comparison of the effects of the vitamin D3 adequate intake versus 100 mcg (4000 IU) per day on biochemical responses and the wellbeing of patients. Vieth R, Kimball S, Hu A, Walfish PG. Nutr J. 2004 Jul 19;3:8. PMID: 15260882 doi:10.1186/1475-2891-3-8 CONCLUSION: The highest AI for vitamin D brought summertime 25(OH)D to >40 nmol/L, lowered PTH, and its use was associated with improved wellbeing. The 100 mcg/day dose produced greater responses. Since it was ethically necessary to provide a meaningful dose of vitamin D to these insufficient patients, we cannot rule out a placebo wellbeing response, particularly for those on the lower dose. This work confirms the safety and efficacy of both 15 and 100 mcg/day vitamin D3 in patients who needed additional vitamin D.

Vitamin D2 is much less effective than vitamin D3 in humans. Armas LA, Hollis BW, Heaney RP. J Clin Endocrinol Metab. 2004 Nov;89(11):5387-91. PMID: 15531486 Vitamin D2 potency is less than one third that of vitamin D3. Physicians resorting to use of vitamin D2 should be aware of its markedly lower potency and shorter duration of action relative to vitamin D3.

Conclusions: Healthy men seem to use 3000-5000 IU cholecalciferol/d, apparently meeting > 80% of their winter cholecalciferol need with cutaneously synthesized accumulations from solar sources during the preceding summer months. Current recommended vitamin D inputs are inadequate to maintain serum 25-hydroxycholecalciferol concentration in the absence of substantial cutaneous production of vitamin D.
