Hints that suicide is associated with low vitamin D:
- Suicide peaks in the Spring, when vitamin D values are lowest
- Suicide has increased while vitamin D has been decreasing
- Suicide higher in dark-skinned individuals (low vitamin D due to built-in sun protection)
- Suicide higher in prison (shut-ins have low levels of vitamin D)
- Suicide attempts in males 3.7 X more likely if poor CYP24A1 gene (less D to cells)
- Suicide rate is higher at high latitudes (where vitamin D is less available)

Vitamin D to veterans likely to suicide, 45% decrease in suicide attempts - Feb 2023
The association between vitamin D serum levels, supplementation, and suicide attempts and intentional self-harm
Jill E. Lavigne,Jason B. Gibbons
PLOS x Feb 1, 2023 https://doi.org/10.1371/journal.pone.0279166
Note: No record of how much vitamin D was given,
No record of if it was actually taken,
No record of how long it was taken
No record of vitamin D levels before or after
Conclusion: fewer suicide attempst in those prescribed with vitamin D
The purpose of this study is to determine the associations between Vitamin D supplementation, 25(OH) blood serum levels, suicide attempts, and intentional self-harm in a population of veterans in the Department of Veterans Affairs (VA).
A retrospective cohort study of US Veterans supplemented with Vitamin D. Veterans with any Vitamin D3 (cholecalciferol) or Vitamin D2 (ergocalciferol) fill between 2010 and 2018 were matched 1:1 to untreated control veterans having similar demographics and medical histories. Cox proportional hazards regression was used to estimate the time from the first Vitamin D3 (cholecalciferol) or Vitamin D2 (ergocalciferol) prescription fill to the first suicide attempt or intentional self-harm. Analyses were repeated in stratified samples to measure associations by race (Black or White), gender (male or female), blood levels (0–19 ng/ml, 20–39 ng/ml, and 40+ ng/ml), and average daily dosage.
Vitamin D3 and D2 supplementation were associated with a 45% and 48% lower risk of suicide attempt and self-harm (D2 Hazard Ratio (HR) = 0.512, [95% CI, 0.457, 0.574]; D3 HR = 0.552, [95% CI, 0.511, 0.597]. Supplemented black veterans and veterans with 0–19 ng/ml vitamin D serum levels were at ~64% lower risk relative to controls (Black Veteran HR: 0.362 [95% CI: 0.298,0.440]; 0–19 ng/ml HR: 0.359 [95% CI: 0.215,0.598]). Supplementation with higher vitamin D dosages was associated with greater risk reductions than lower dosages (Log Average Dosage HR: 0.837 [95% CI: 0.779,0.900]).
Vitamin D supplementation was associated with a reduced risk of suicide attempt and self-harm in Veterans, especially in veterans with low blood serum levels and Black veterans.

The Association Between Low Vitamin D Levels and Suicide Attempts in Adolescents
Ann Clin Psychiatry, 32 (1), e1-e8 2020 Feb 1
Gamze Gokalp 1
Background: Psychiatric disorders are the most common cause of suicide attempts. Some studies have shown there is a relationship between low vitamin D levels and psychiatric disorders. In this study, we examined the relationship between suicidal behavior and vitamin D levels in adolescents.
Method: This study included 215 patients who presented to the pediatric emergency department due to a suicide attempt (patient group) and 200 healthy individuals (control group). Demographic and clinical features of both groups were recorded, and serum vitamin D, calcium, and phosphorus levels were measured. The groups were compared in terms of these factors. All data were analyzed using the SPSS 20.0 (SPSS Inc., Illinois, USA) software program.
Results: The mean vitamin D level was 19.4 ± 10 ng/mL in the control group and 12.3 ± 6 ng/mL in the patient group (t = 8.8 and P = .01). The mean serum total calcium level was 9.9 ± 0.3 mg/dL in the control group and 9.4 ± 0.5 mg/dL in the patient group (P < .01).
Conclusions: Vitamin D deficiency, which is a treatable condition, may be one of the causes of suicidal behavior in adolescents. Therefore, we believe that physicians who treat adolescents should consider vitamin D levels in routine examinations.

Vitamin D deficiency is associated with immune dysregulation, increased vulnerability to infections, depression, and suicidal behavior. One mediator of vitamin D-dependent immune regulation and antimicrobial defense is the cathelicidin antimicrobial peptide (LL37), encoded by the cathelicidin-related antimicrobial peptide (CRAMP) gene. We compared the mRNA expression of the CRAMP gene, the vitamin D receptor (VDR) gene, as well as the CYP27B1 and CYP24A1 genes (involved in vitamin D metabolism) in the dorsolateral prefrontal cortex (dlPFC) and anterior cingulate cortex (ACC) between depressed individuals who died by suicide (n = 15) and matched (age, gender, and post-mortem interval) non-psychiatric controls (n = 15). Gene expression was measured through qRT-PCR with TaqMan® primers and probes, with GAPDH and β-actin genes as endogenous controls. Statistical analyses included t-tests and Pearson correlations. CRAMP mRNA expression was downregulated and VDR mRNA expression was upregulated in both dlPFC and ACC in suicides relative to controls, with no significant differences in expression of CYP24A1 and CYP27B1. To our knowledge, this is the first study on brain cathelicidin expression in the human brain in relationship to suicide. Increased VDR and decreased CRAMP expression are consistent with previously reported associations between vitamin D deficiency, immune dysregulation, and suicidal behavior, and should lead to future studies uncovering novel interactive targets for suicide prevention.

Low levels of vitamin D may play a role in psychiatric disorders, as cross-sectional studies show an association between vitamin D deficiency and depression, schizophrenia and psychotic symptoms. The underlying mechanisms are not well understood, although vitamin D is known to influence the immune system to promote a T helper (Th)-2 phenotype. At the same time, increased inflammation might be of importance in the pathophysiology of depression and suicide. We therefore hypothesized that suicidal patients would be deficient in vitamin D, which could be responsible for the inflammatory changes observed in these patients.
We compared vitamin D levels in suicide attempters (n = 59), non-suicidal depressed patients (n = 17) and healthy controls (n = 14). Subjects were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, and went through a structured interview by a specialist in psychiatry. 25(OH)D2 and 25(OH)D3 were measured in plasma using liquid-chromatography–mass-spectrometry (LC–MS). We further explored vitamin D's association with plasma IL-1β, IL-6 and TNF-α.
Suicide attempters had significantly lower mean levels of vitamin D than depressed non-suicidal patients and healthy controls. 58 percent of the suicide attempters were vitamin D deficient according to clinical standard. Moreover, there was a significant negative association between vitamin D and pro-inflammatory cytokines in the psychiatric patients. Low vitamin D levels were associated with higher levels of the inflammatory cytokines IL-6 and IL-1β in the blood.
The suicide attempters in our study were deficient in vitamin D. Our data also suggest that vitamin D deficiency could be a contributing factor to the elevated pro-inflammatory cytokines previously reported in suicidal patients. We propose that routine clinical testing of vitamin D levels could be beneficial in patients with suicidal symptoms, with subsequent supplementation in patients found to be deficient.

Considering that epidemiological studies show that suicide rates in many countries are highest in the spring when vitamin D status is lowest, and that low vitamin D status can affect brain function, we sought to evaluate if a low level of 25-hydroxyvitamin D [25(OH)D] could be a predisposing factor for suicide.
We conducted a prospective, nested, case-control study using serum samples stored in the Department of Defense Serum Repository. Participants were previously deployed active duty US military personnel (2002–2008) who had a recent archived serum sample available for analysis. Vitamin D status was estimated by measuring 25(OH) D levels in serum samples drawn within 24 months of the suicide. Each verified suicide case (n = 495) was matched to a control (n = 495) by rank, age and sex. We calculated odds ratio of suicide associated with categorical levels (octiles) of 25(OH) D, adjusted by season of serum collection.
More than 30% of all subjects had 25(OH)D values below 20 ng/mL. Although mean serum 25(OH)D concentrations did not differ between suicide cases and controls, risk estimates indicated that subjects in the lowest octile of season-adjusted 25(OH)D (<15.5 ng/mL) had the highest risk of suicide, with subjects in the subsequent higher octiles showing approximately the same level of decreased risk (combined odds ratio compared to lowest octile = 0.49; 95% C.I.: 0.315–0.768).
Low vitamin D status is common in active duty service members. The lowest 25(OH)D levels are associated with an increased risk for suicide. Future studies could determine if additional sunlight exposure and vitamin D supplementation might reduce suicide by increasing 25(OH) D levels.

"A comment from the authors, but not an observation from the study:"
“an increasing number of reports raise the possibility that statins, a class of lipid-lowering agents, may be associated with deleterious cognitive, mood and behavioural adverse effects, including violence, depression and suicide, which have been attributed to the effect of statins’ cholesterol level reduction on brain function.”
