Vitamin D Will Help In Seasonal Affective Disorder.

Vitamin D: Experts discuss if it eases seasonal depression symptoms, like changes in sleep and feeling of sadness.

It's wintertime once again. For many of us who live far from the equator, late autumn and winter are welcome seasons ... building snowmen, sport and sledding are all popular snowy pastimes.

What is Seasonal Affective Disorder (SAD)?


Seasonal affective disorder (SAD) is prevalent when Vitamin D stores are typically low. Broad-spectrum light medical aid includes wavelengths between 280-320 nm which permit the skin to produce Vitamin D. This study was designed to check the hypothesis that Vitamin D deficiency may play a role in sad. A prospective, randomized controlled trial was conducted in a group of 15 subjects with sad.

Instead, people with SAD display the following symptoms:

  1. Depressed mood
  2. Anxiety
  3. Irritability
  4. Weight gain
  5. Lethargy
  6. Difficulty with concentration
  7. Carbohydrate craving
  8. Decreased libido
  9. Sleepiness
  10. Hyperphagia (Increased consumption of food)

This disorder is more common in women than in men. although some children and teenagers are affected, sad usually happens in people between 18 and 30 years of age. A new Danish study examines Vitamin D supplementation as possible benefit for sad symptoms.

One popular method for treating SAD is Vitamin D, that most of the people naturally get from their diet and especially daylight (something the wintertime very clearly lacks). It’s believed that Vitamin D can help manage the debilitating symptoms of the mental health condition, which include a lack of motivation, changes in sleep patterns, increased irritability and sadness.

A meta-analysis published in 2018 also found a correlation between lower Vitamin D levels and depression, the BBC reported, but that doesn’t essentially mean it’s the explanation for the illness.

It simply indicates that the two existed at the same time. (Since a symptom of depression is withdrawal, it’s possible that those living with the unwellness didn’t go outside enough to get normal amounts of Vitamin D, the BBC pointed out.)

Unfortunately, researchers found that Vitamin D supplementation had an insignificant effect on both primary and secondary outcomes. In alternative words, the researchers found that Vitamin D supple-mention did not help with sad symptoms.  Of note, and as conceded by the researchers, there have been some serious limitations with the study.


Most notably, the study was under powered with a mere 34 people completing the study. in addition, researchers weren't able to examine Vitamin D supplementation in people who had low levels of Vitamin D in their blood or low 25(OH)D.

Given that sad is a complex illness, experts can’t solely pin its presence on a lack of Vitamin D. mental health disorders usually develop due to a person’s environment, circumstances, physiology or a combination of these things.
