Vitamin D
















Why do you tend to feel happier during summer than winter?


The absence of Vitamin D contributes to the progression of depression and chronic fatigue. This is because it helps to regulate hormones critical to mood, stress management and energy.


Seasonal depression, which typically occurs during winter, is linked to being insufficiently exposed to sunlight. Researchers at the University of California and the University of Vienna have found that a single hour of bright-light therapy is an extremely successful way to alleviate the symptoms of depression (Holick, 2014).


Vitamin D is made in the body when cholesterol in the skin is radiated by ultraviolet rays from the sun (Peate, 2014). According to Stephen Honig, director of the Osteoporosis Center at the Hospital for Joint Diseases, 20 to 25 minutes of exposure to direct sunlight will help produce it (Quittner, 2016).


This vitamin is also crucial for bone repair and construction. It is required for calcium absorption which is part of bone formation. Its deficiency causes rickets in children, which is a disease that makes the bones become soft and misshaped. Its lack in adults results in osteoporosis and osteomalacia (Fonseca, 2013).


Foods that provide Vitamin D include:

  • Egg yolks

  • Oily fish (such as salmon, herring and mackerel)

  • Mushrooms

Supplements of this vitamin in the form of tablets and drops are available to be bought online and at pharmacies.


My children’s pediatrician prescribes a dosage for them which we collect from our local pharmacy. They consume the 4000 U.I/ ml LuVit D3 by the brand Drossapharm.

Overall, we take Vitamin D to strengthen our mental health as well as immune system in order to prevent these diseases and disorders.
