Vitamin B complex
A study carried out in Australia examined the effects of a 3 month treatment of two forms of high dose vitamin B complex on mood and psychological strain associated with chronic work stress.
Results showed that the vitamin B complex treatment groups had significantly lower personal strain and a reduction in confusion and depressed/dejected mood after 12 weeks, compared to the control group.
Vitamins C, A and E
There are numerous lab studies that show the importance of the antioxidant effects of Vitamins C and E in reducing anxiety. The most recent patient centered study that Patient QI found was published in 2012. The study investigated whether the blood serum levels of Vitamins A, C and E are different in patients with generalized anxiety disorder compared to a normal healthy control group. The patient group were then treated with a 6 weeks supplementation of the vitamins and before and after results were compared. Results showed that the patients had significantly lower levels of vitamins A, C and E compared to controls and the 6 week treatment led to a significant decrease in anxiety and depression.
Hops (Humulus lupulus)
Hops have a long traditional use as a sedative and hops are a major component of beer. A study carried out in Spain analyzed the sedative effects of alcohol free beer on the sleep/wake rhythm in a work stressed population, represented by healthy female nurses working on a rotation night/day shifts. Results showed that one 333ml alcohol free drink of beer per day with supper favored night time rest and decreased anxiety.
