Vitamin D improved mood in adolescent females
Doctors wanted to see if vitamin D in high doses could reduce the intensity of premenstrual-syndrome (PMS) related mood disorders in young women severely deficient in vitamin D. In the study, 158 women, aged 15 to 21, with severe PMS symptoms and vitamin D levels no higher than 10 nanograms per milliliter of blood (ng/mL), took a placebo or an initial dose of 200,000 IU of vitamin D followed by 25,000 IU every two weeks for four months.
After one month, the vitamin D group reached normal vitamin D levels of 35 to 60 ng/mL, and remained there throughout the study. After four months, while there were no measureable improvements for placebo, anxiety scores decreased to 20 from 51; irritability scores to 70 from 130; crying easily to 30 from 41, and sadness scores to 31 from 51 for the vitamin D group. In a measure of "disturbed relationships," scores improved to 70 from 150 before vitamin D.

Additional Comments from Don Goldberg
This is a very impressive study, and is one of many studys that indicate we can benefit from significant increases in our vitamin D levels. The concern about vitamin D among nutritionists used to be “are you getting too much?” Now, the concern is “are you getting enough.”
The old recommended dosage level of 400 IU is widely ignored by physicians and nutritionists, and a dose of 1,000 IU per day is now considered moderate. Most physicians suggest adding vitamin D levels to your routine blood scan. Most people’s results are significantly below normal.
Typical dosages of vitamin D3 now available as nutritional supplements run from 1,000 IU to 10,000 IU per capsule. Healthy Origins, for example, offers potencies of 1000 IU, 1200 IU, 2000 IU, 2400 IU, 5000 IU and 10000 IU–all at very reasonable prices.
The pharmacists and nutritionists at Willner Chemists will be happy to assist you in finding the most appropriate vitamin D3 supplement for your needs.
