Intervention of Vitamin D for Depression
- Major Depressive Disorder RCTs often use Vitamin D: 50,000 IU weekly or single 300,000 IU - Review May 2025
- Depression cost-effectively reduced by 50,000 IU of Vitamin D monthly (Iranian teens) – July 2023
- Infants getting an additional 800 IU of vitamin D for 2 years had 60% fewer psychiatric symptoms at age 7 – RCT May 2023
- Anxiety and Depression decreased in senior prediabetics with weekly 25,000 IU of Vitamin D – RCT Sept 2022
- Depression decreased by Vitamin D (12th study in VitaminDWiki) – RCT Nov 2022
- Overweight needed more EPA (4 grams) to fight depression – RCT Aug 2022
- Smoking depression, etc. reduced by Vitamin D (bi-weekly, 50,000 IU) - RCT Dec 2021
- Omega-3 did not prevent depression (they failed to reduce Omega-6, which blocks Omega-3) – RCT Dec 2021
- Weekly Vitamin D plus daily Magnesium is great (reduced depression in obese women in this case) – July 2021
- Depression in psychiatric youths reduced 28 percent after just 1 month of vitamin D – RCT Feb 2020
- Yet another study confirms Depression is treated by weekly Vitamin D (50,000 IU)– RCT Dec 2019
- Depression decreased after vitamin D (50,000 IU weekly to elderly in the case) – RCT Oct 2019
- Vitamin D - no cure for depression (when you use only 1200 IU) – Aug 2019
- Depression reduced in Diabetics with 3 months of 4,000 IU of vitamin D – RCT July 2019
- Vitamin D treatment of diabetes (50,000 IU every 2 weeks) augmented by probiotic – RCT June 2018
- Women had better sexual desire, orgasm and satisfaction after Vitamin D supplementation – Feb 2018
- Vitamin D depression RCT canceled: too many were taking Vitamin D supplements, etc. Feb 2018
- Depression in adolescent girls reduced somewhat by 50,000 IU weekly for 9 weeks – July 2017
- Perinatal depression decreased 40 percent with just a few weeks of 2,000 IU of vitamin D – RCT Aug 2016
- Just 1500 IU of Vitamin D significantly helps Prozac – RCT March 2013
- Reduced depression with single 300,000 IU injection of vitamin D – RCT June 2013
- 40,000 IU vitamin D weekly reduced depression in many obese subjects – RCT 2008
- 50,000 IU Vitamin D weekly Improves Mood, Lowers Blood Pressure in Type 2 Diabetics – Oct 2013
Meta-analyses of Vitamin D and Depression
- Depression reduced by 8,000 IU of Vitamin D daily – meta-analysis Nov 2024
- Depression 1.6 X more likely if low Vitamin D, taking Vitamin D reduces depression – umbrella of meta-analyses – Jan 2023
- Depression in seniors greatly reduced by Vitamin D (50,000 IU weekly) – meta-analysis June 2023
- Depression reduced if take more than 5,000 IU of vitamin D daily – umbrella meta-analysis – Jan 2023
- Depression reduced if use more than 2,800 IU of vitamin D – meta-analysis Aug 2022
- Depression is treated by 2,000 IU of Vitamin D – 2 meta-analyses July 2022
- Depression treated by 50K IU Vitamin D weekly (but not 1,000 IU daily) – meta-analysis Jan 2021
- Mental disorders fought by Omega-3 etc. - meta-meta-analysis Oct 2019
- Depression less likely if more Vitamin D (12 percent per 10 ng) – meta-analysis July 2019
- Anxiety severity reduced if more than 2 grams of Omega-3 – meta-analysis Sept 2018
- Less depression in seniors taking enough Omega-3 – meta-analysis July 2018
- Unipolar depression treated by Omega-3, Zinc, and probably Vitamin D – meta-analysis Oct 2017
- Depression is associated with low Magnesium – meta-analysis April 2015
- Clinical Trials of vitamin D can have “biological flaws” – Jan 2015
- Slight depression not reduced by adding vitamin D if already had enough (no surprise) – meta-analysis – Nov 2014
- Anti-depression medication about as good as big increase in vitamin D – meta-analysis of flawless data April 2014
- Depression might be reduced by vitamin D – meta-analysis March 2014
- Low vitamin D and depression - Study and meta-analysis, April 2013
- 2X more likely to be depressed if low vitamin D (cohort studies) - Meta-analysis Jan 2013

"Students with severe depression had more vitamin d deficiency (67.1%) than others (32.9%)."
Objectives: The aim of this study was to explore the association between vitamin D deficiency and depression among university students and to identify the factors affecting this association.
Methodology: A cross-sectional study was conducted between 1st January and end of March 2017 among university students from 39 different countries.
Results: 699 students were participated in this study. The findings of this study found that 270 students (38.6%) had vitamin D deficiency with level less than 20. The findings of this study found that majority of students (99.9%) in this study had depression. The findings of this study found that there was no association between depression and vitamin D depression (p value=0.386). The findings of this study shows that there was a significant difference between the severe groups of depression and other classes in terms of prevalence of vitamin D deficiency (p value=0.000).
Conclusion: The current study shows that there was no association between vitamin D deficiency and depression. On the other hand, there were significant associations between the severity of depression and vitamin D deficiency. Lack of sun exposure; diet and financial factors were the causes of vitamin D deficiency in this study. Further studies are highly recommended to investigate the causes of depression among students.
