What This Study Did, in Plain Language
What Was Tested
This observational study looks at Vitamin D, K2, Magnesium and Zinc and Parathyroid Hormone (PTH 1-84).
The aim of this study was to investigate vitamin D status and seasonal changes in summer and winter in office workers.
Why It Was Studied
Lack of sun exposure is one of the primary causes of epidemic vitamin D deficiency worldwide.
Who Took Part
The study group was 118 women.
PubMed indexes the participants as young adults, adults and middle-aged adults, both men and women.
The study consisted of 118 premenopausal women and men aged between 21 and 52 years-old.
How the Study Was Run
Seasonal changes were evaluated in August and February.
Fasting serum was obtained for intact parathyroid hormone (iPTH) and 25-hydroxyvitamin D (25OHD).
Additional data were collected by a questionnaire that enquired about age, weight, height, wearing style, dietary calcium intake and sunlight exposure.
Serum 25OHD concentration was measured using a precise HPLC assay.
Low vitamin D status was defined as a 25OHD concentration less than 30 ng/mL.
What Was Measured
Lack of sun exposure is one of the primary causes of epidemic vitamin D deficiency worldwide.

Our Notes on the Compounds
Vitamin D, K2, Magnesium and Zinc: Magnesium is described as required for AMPK to function.
Parathyroid Hormone (PTH 1-84): The 84-amino-acid hormone that raises blood calcium; full-length PTH (Natpara) has been used in hypoparathyroidism. Teriparatide is its 1-34 fragment.
