  • For all adults aged 19 - 65
  • Lifetime prevalence of anxiety disorders in (US) adults was 26 % for men and 40 % for women (as of 2002)
  • Anxiety and depressive disorders often overlap. One cohort study found that 67% of individuals with a depressive disorder also had a current anxiety disorder, and 75% had a lifetime comorbid anxiety disorder

Vitamin D reduces depression (4,000+ IU daily for 8+ weeks) - meta-analysis May 2020

The effect of vitamin D supplement on negative emotions: A systematic review and meta-analysis
Depression and Anxiety May 2020 https://doi.org/10.1002/da.23025
Ying-Chih Cheng, Yu-Chen Huang, Wei-Lieh Huang

The several meta-analyses of the effect of vitamin D on depression have produced inconsistent results and studies dealing with anxiety were not incorporated. There has been no comprehensive analysis of how results are affected by the nature of the sample or the dosage and duration of supplementation. The study is aimed to investigate whether vitamin D supplementation reduces negative emotions and to analyze the possible influence of sample and regimen.

We conducted a systematic review and meta-analysis of randomized controlled trials comparing the effect of vitamin D and placebo on negative emotion. Databases were searched for relevant articles published before February 2019.

The analysis covered 25 trials with a total of 7,534 participants and revealed an effect of vitamin D on negative emotion (Hedges' g = −0.4990, 95% CI [−0.8453, −0.1528], p = .0047, I2 = 97.7%). Subgroup analysis showed that vitamin D had an effect on patients with major depressive disorder and on subjects with serum 25(OH)D levels ≤50 nmol/L. The pooled data from trials of vitamin D supplementation lasting ≥8 weeks and dosage ≤4,000 IU/day indicated that vitamin D had an effect.

Our results support the hypothesis that vitamin D supplementation can reduce negative emotions. Patients with major depressive disorder and individuals with vitamin D deficiency are most likely to benefit from supplementation. But to interpret the results with high heterogeneity should still be cautious.

Depression decreased by 300,000 IU injection of Vitamin D - RCT Oct 2020

Effect of adjunctive single dose parenteral Vitamin D supplementation in major depressive disorder with concurrent vitamin D deficiency: A double-blind randomized placebo-controlled trial
J. of Psychiatric Research Vol 129, Oct 2020, Pages 250-256 https://doi.org/10.1016/j.jpsychires.2020.07.037 PDF is behind a paywall

Adjunctive vitamin D replacement is a theoretically promising strategy to improve outcomes in major depression. Our objective was to assess the efficacy of a single parenteral dose of vitamin D supplementation at baseline as an adjunct to treatment as usual on change in depression symptom ratings (primary outcome), quality of life and clinical severity of illness (secondary outcomes) at the end of 12 weeks when compared to treatment as usual in patients with major depression and concurrent Vitamin D deficiency. Eligible participants were randomized to receive either treatment as usual (TAU; n = 23) or TAU plus single parenteral dose of 3,00,000 IU of vitamin D (n = 23) at baseline. Rater-blinded assessments of depression (primary outcome), quality of life (QoL) and clinical severity of illness were obtained at baseline, and end of follow-up (12 weeks). Intent-to-treat analyses were performed on the entire randomized sample. The intervention significantly improved depression symptom ratings, quality of life and clinical severity of illness at the end of the treatment phase. These findings indicate that a single parenteral dose (3,00,000 IU) of adjunctive vitamin D replacement at baseline is an effective and well tolerated intervention in major depressive disorder with concurrent Vitamin D deficiency. Additionally, it points to a possible role for vitamin D in the pathophysiology of depression and supports personalized approaches for treatment of major depressive disorder.

Depresssion drugs, including SSRI

Just How Far Will the FDA Go To Protect A Bad Drug? (SSRI Dec 2023)


  • "While the FDA initially tried to stop Prozac, once Bush came to power (as his family was in bed with Prozac’s manufacturer), the FDA reversed course."
  • "Since that time, the FDA has gone to extremely lengths to cover up the harms of antidepressants. Much of what the FDA did with the SSRIs was identical to what it’s done with the COVID vaccines and I believe learning what happened in the past is highly instructive for understanding what the FDA is doing now and how to stop it."
  • "Note: Psychiatric medications are one of the most profitable drug franchises, making approximately 40 billion dollars a year"


  • "This study found that SSRIs increased the rate of violent crimes committed by 43% in those between the ages of 15 and 24 receiving the drugs."
  • "... a much larger survey of SSRI users found 39% had experienced suicidal ideation while on the drugs."

  • " 10-year data from the UK Biobank on over 220,000 adults "
  • "The main culprits were mirtazapine, venlafaxine, duloxetine, and trazodone, although SSRIs were also tied to increased risk"

SSRIs cause long term sexual dysfunction (prescription warnings in Europe and Canada)
  • Antidepressants (SSRI) can cause 'chemical castration' June 2023
    • "In a study from 2001 involving >1000 patients with no previous history of sexual problems, 59% reported sexual dysfunction after commencing an antidepressant. For the five most commonly used drugs, 46% experienced no orgasm or ejaculation."
    • No change by the FDA, but "In June 2019, the European Medicines Agency updated the ‘Special Warnings and Precautions’ section on the label of SSRIs to warn that sexual dysfunction can persist even after treatment stops."
    • Canada also changed

Post-SSRI Sexual Dysfunction

  • "Close to 100% of people who take antidepressants experience some form of sexual side effects."
  • "Commonly used SSRIs include paroxetine (Paxil, Seroxat), fluoxetine (Prozac), sertraline (Zoloft), citalopram (Celexa), escitalopram (Lexapro), and vortioxetine (Trintellix)."
  • "The RxISK Prize of $100,000 USD is offered to anyone who can provide a cure for persistent sexual side effects after stopping antidepressants, finasteride, or isotretinoin."

Why Are Antidepressants (SSRIs) so Harmful? - Nov 2023

Subtack Nov 26, 2023

  • "Like many other stimulant drugs (e.g., cocaine) SSRIs are highly addictive. Because of this, patients will get severely ill when they attempt to stop them (withdrawals affect roughly half of SSRI users) and it is often extremely difficult to withdraw from them. In this article, I will cover the approaches I know for that since very few resources exist for people in that situation."
  • "For example, in a survey of 1,829 patients on antidepressants in New Zealand,
    • 62% reported sexual difficulties,
    • 60% felt emotionally numb,
    • 52% felt not like themselves,
    • 39% cared less about others,
    • 47% had experienced agitation and
    • 39% had experienced suicidal ideation."
  • "•An international survey of 3,516 people from 14 patient advocacy groups found that 44% had permanently stopped taking a psychiatric drug due to its side effects."

How to make better use of antidepressants - The Economist


  • Antidepressant "drugs had a substantial effect on depression beyond that of a placebo for only 15% of patients."
  • "A study published in 2010, which examined research on two common ssris, estimated that for people with less severe depression the odds of improving by taking the drugs were just 6% higher than they were for taking a placebo. "
  • "A review of the research published on that topic, carried out in 2019, found that between 27% and 86% of people attempting to come off antidepressants experienced withdrawal symptoms, and that nearly half of them described those symptoms as severe."
