Vitamin D additionally has a duty in serotonin (the “feel excellent neurotransmitter”) synthesis along with in aiding to moderate our stress and anxiety levels. Understanding of these features has resulted in research study on D and Seasonal Affective Disorder (SAD).

Signs and symptoms of SAD consist of:

Reduced energy
Really feeling sad a lot of the day on many days

The jury is still out on the result of vitamin D shortage on SAD– there is research study on both sides of this, some showing little connection in between reduced vitamin D and mood, and various other studies show support for vitamin D supplementation as a therapy for SAD in people that lack vitamin D.

Season, time of day, length of day, cloud cover, smoke, skin melanin content, and sunscreen are amongst the factors that impact sun direct exposure and also vitamin D synthesis.

We also obtain vitamin D in food, nonetheless it can be extremely hard to get all we require from food, specifically in the months of winter.
