Vitamin D and Seasonal Affective Disorder

IAS News 11 December 2014 | 0 Comments

We have brought several stories over the years linking vitamin D deficiencies to increased risk of asthma, chronic pain, high blood pressure, muscle weakness, poor oral health, diabetes and many others. Recently it has been suggested that it could also be linked to Seasonal Affective Disorder.

Seasonal Affective Disorder is thought to affect up to 10% of the population, with symptoms ranging from feeling sad, or anxious, fatigue, problems with concentration, irritability and feelings of guilt and general hopelessness. Many studies have linked these feelings with a lack of sunlight, the condition seems to have higher concentrations in areas of lots of cloud.

The most recent study into this has pointed out how vitamin D levels fluctuate with the seasons in response to the availability of sunlight. As well as playing a part in the synthesizing of both dopamine and serotonin, with past research showing how low levels of these have been associated with depression.

The link between health and vitamin D is well documented and a study was done earlier this year to look into the ideal dosage in order to correct the deficiency and maintain normal levels within a population. The study details can be found here. The general conclusion from the study was that the recommended daily allowance is hugely inadequate for correcting low levels. It is thought that about 5000IU daily is needed to correct a deficiencyand a maintenance dose should be about 2000IU daily.

IAS carries two high strength vitamin D products including one at 5000IU and one at 50,000IU. The 5000IU one is suggested for those wanting to boost their levels for general health maintenance, and the higher 50,000IU is more for those with specific ailments that need treating.
