Can Vitamin D Levels Predict Depression?
You probably know that vitamin D plays an important role in your health http://www.dreddyclinic.com/forum/viewtopic.php?f=33&t=33211, helping to absorb calcium and promote bone growth. It’s also possible that you have heard that Vitamin D deficiency has been linked to a variety of health problems, including rickets, breast cancerhttp://www.dreddyclinic.com/findinformation/cc/breastcancer.php, heart disease, and weight gain. But what you most likely haven’t heard is that in addition to these serious issues, experts believe that vitamin D deficiency may be tied to depression.
Vitamin D and Depression
A recent study may confirm the link between low levels of vitamin D and depressive symptoms http://dreddyclinic.com/forum/viewtopic.php?f=109&t=33595. [1] The study assessed 185 healthy young women over four weeks, measuring their vitamin D levels and symptoms of depression. Researchers found that nearly half of the participants had vitamin D deficiency, and over a third had symptoms of clinically significant depressive symptoms.
When examining data from the study, investigators took factors such as season, body mass index, diet, exercise, and race into account. They found that lower vitamin D levels across the month-long period predicted symptoms of depression http://www.dreddyclinic.com/findinformation/dd/depression.php, and the only other factor that could predict such symptoms was the use of antidepressants.
Vitamin D: A Potent Fighter for Depression?
More research is needed to fully understand the relationship between vitamin D and depression http://dreddyclinic.com/forum/viewtopic.php?f=109&t=33595 but this study is an interesting start. Vitamin D is an essential nutrient and it’s highly advisable to maintain a healthy level of vitamin D to promote bone growth and reduce the risk of other health problems.

Top Natural Remedies For Depression
The experience of emotional and psychological depression has been noted and subjected to various explanations since the dawn of recorded history and quite probably before. The current model, which reduces all depression to a deficiency in serotonin, seems as overly simplistic and inadequate as those before it. This is to say, at least in part, that depression is a complex and age-old illness with a storied history of treatment. There are a number of herbs that have been used successfully to help relieve symptoms of depression, and thoughtful consideration of various root causes of psychological malaise can serve to steer one toward improvement.
Recent studies have reinforced the potential efficacy of a number of traditional herbal aids for depression.
St. John’s Wort (Hypericum perforatum)
One of the most widely known herbs purported to help with depression; St. John’s Wort (Hypericum perforatum) has been the subject of much debate in recent years. While the data on St. John’s Wort is confusing to say the least, it is worth noting its long and extensive use throughout the world, along with several independent investigations reinforcing its efficacy. A 2009 meta-analysis by the Cochrane Collaboration concluded that “Overall, the St. John’s wort extracts tested in the trials were superior to placebo, similarly effective as standard antidepressants, and had fewer side effects than standard antidepressants [1].”
Another thoughtful and extensive meta-analysis published by four physicians in the British Journal of Psychiatry considered 37 prior studies and found that “Hypericum perforatum extracts improved symptoms more than placebo and similarly to standard antidepressants in adults with mild to moderate depression [2].” Furthermore, hypericum extracts caused fewer adverse effects than questionable antidepressants.
Rhodiola (Rhodiola rosea)
Lesser known, but also an interesting aid in depression is the adaptogen Rhodiola (Rhodiola rosea). In a very well designed and executed study of Rhodiola rosea, 89 individuals, male and female, ranging from 18-70 years of age and selected according to DSM-IV criteria for depression, were divided into three groups. One group received 340 mg of rhodiola per day, in two tablets, a second received 680 mg/day in two tablets and a third received two placebo tablets. Both groups receiving the rhodiola experienced significant improvements in overall depression, insomnia, emotional instability and somatization as scored in the Beck Depression Inventory and Hamilton Rating Scale for Depression (HAMD) questionnaire. The placebo group showed no such improvement. No serious side effects were reported among any of the three groups [3].
Black Cohosh (Cimicifuga racemosa)
This herb has been used extensively to relieve depression that occurs during menopause or in other times of hormonal fluctuation. Recent debate about possible liver damage resulting from long-term and excessive use is worthy of note, but certainly not reason to disregard the potential benefits of this herb. Like all herbal remedies, responsible use requires responsible consideration of the whole cost-benefit picture.
Rhaponticum (Rhaponticum carthanmoides)
Another interesting alternative for menopause related mood disorders is Rhaponticum (Rhaponticum carthanmoides): in a study of 109 women, published in 2007 in the journal Menopause, over 80% of women who took Rhaponticum daily for twelve weeks reported a “a marked improvement in health state and general well-being.”
Lavender and Lemon Balm (Melissa officinalis)
Two lovely herbs to investigate: Lavender and Lemon Balm (Melissa officinalis). A fascinating study from the Neuroscience Unit of University of Northumbria in Newcastle found that a 600 mg serving of melissa officinalis alleviated the physiological effects of laboratory induced stress in healthy individuals, suggesting that the herb may have great potential in mitigating deleterious effects of stress outside the laboratory [4].
