Seasonal Depression, also known as Seasonal Affective Disorder, is a disorder that affects approximately 6% of the US population. This form of depression can range in severity, but common symptoms include: an increased desire for carbohydrate foods, irritability, weight fluctuation, an increase in sleep, a decrease in energy, as well as a loss of interest in regularly enjoyable activities. Liquid Health, Inc. has a liquid vitamin supplement that may help to control these symptoms.
There are a variety of treatment options available for a person suffering from Seasonal Depression. The most common treatments include light therapy and prescription medications. Studies have been done to test the affect of Vitamin D supplementation on Seasonal Depression symptoms, based on the relationship between winter months and a decrease in sun exposure, leading to lower natural levels of Vitamin D in the body.
Two studies found a decrease in Seasonal Depression symptoms when study participants were given supplemental Vitamin D. The first study, published in Psychopharmacology in February 1998, stated “Forty-four healthy subjects were given 400 IU, 800 IU, or no vitamin D3 for 5 days during late winter in a random double-blind study. Results on a self-report measure showed that vitamin D3 significantly enhanced positive affect.” The other study, published in the Journal of Nutrition, Health and Aging (1999;3(1):5-7) compared the results of Vitamin D supplementation with phototherapy and found that “All subjects receiving vitamin D improved in all outcome measures. The phototherapy group showed no significant change in depression scale measures.”
Liquid Health, Inc.’s sublingual Vitamin D drops contain 5000 IU of Vitamin D3 per serving. According to Brett Peterson, Director of Business Development for Liquid Health, Inc., “A number of studies show that the natural form of Vitamin D3 outperforms D2 in long term Vitamin D levels and bio-availability, making Vitamin D3 the optimal choice in Vitamin D supplementation.”
