OBJECTIVES: Neurotransmitters regulate mood, attention vigilance and other clinical symptoms linked with depression. Various medications ameliorate symptoms of depression and mood disorders by interference with the serotonic metabolism. Serotonin metabolism depends on nutritional cofactors such as pyridoxin together with essential mineral and trace elements. Both, inflammation and metabolic conditions seem to affect the bioavailability of serotonin crucially. We hypothesized that serotonin supply depends on relevant gastrointestinal precursor absorption and on the availability of nutritive antiinflammatory cofactors.

METHODS: We performed a randomized placebo controlled clinical trial in healthy participants to study the bioavailabilty of ingredients of the multivitamin and trace element LaVita' in a prospective randomized placebo controlled double blind trial to establish the mood ameliorating potential. Serotonin and its precursor tryptophan were measured in dry blood samples. Serum parameters like chromium and zinc, as well as vitamin D, vitamin B3 and B6 were determined before intake, and after 3 months and 6 months consumption of the test substances.

RESULTS: After 3 months a slight increase of tryptophan (p=0.059) and a significant increase of serum serotonin (p < 0.013) was observed in the verum group. After 6 months the verum group showed a highly significant mean increase in niacin (p < 0.001) and the cofactors of serotonin metabolism pyridoxin (p=0.03), chromium p < 0.01), and zinc (p < 0.001). Serotonin levels droped after 6 months indicating a low risk for overdosing.

CONCLUSION: We conclude that a continuous supply with ingredients from the natural source compound LaVita' may contribute to mood improving neurotransmitter activity....

OBJECTIVE: Pregnancy increases the demand for vitamins, including vitamin D. Data on effects of vitamin D deficiency for pregnant woman and fetus available in Poland are scarce. The aim of this study was to evaluate vitamin D3 concentration in pregnant women and its influence on pregnancy course, health of pregnant women and their offspring.

PATIENTS AND METHODS: The study included 102 healthy pregnant women, aged 21 to 40 years, mean 30.5±4.9 years. Women were divided into three groups based on 25(OH)D serum concentration in the third trimester of pregnancy: Group I - with sufficient 25(OH)D serum concentration (>30 ng/ml), Group II - with vitamin D3 insufficiency (20-30 ng/ml), Group III - with serious vitamin D deficiency (<20 ng/ml).

RESULTS: Optimal vitamin D concentrations were found only in 31.2% of women, however in winter months only in 16%. Bacterial vaginosis was significantly more common in women with vitamin D deficiency and insufficiency (p<0.05). In contrast, there were no relations between vitamin D status and the incidence of gestational diabetes, preeclampsia, mode of delivery and size of newborns. A relationship between vitamin D deficiency and insufficiency during pregnancy and subsequent incidence of respiratory infections in children (p<0.05) was demonstrated.

CONCLUSIONS: 1. The current model of vitamin D supplementation in pregnant women in Poland is insufficient, particularly in winter. 2. Vitamin D deficiency in pregnant women fosters development of bacterial vaginosis during pregnancy and recurrent respiratory infections in children, suggestive of the role of vitamin D in prevention of infections....

OBJECTIVE: The broad spectrum of extraosseal functions of vitamin D has recently been investigated. Although majority of recent studies have documented its hypotensive effect, some older studies warrant the risk of development the juvenile hypertension namely after pulse-fortified D vitamin supplementation during infancy. The aim of this study was to compare of the blood pressure in 13 year old groups of adolescents to the mode of D vitamin supplementation during their infancy.

METHODS: Study group represent 1138 thirteen year old adolescents in complex health care of 21 primary care pediatricians (PCPs). This group was divided into three subgroups according their mode of D vitamin supplementation in infancy. 100 children were given the continuous daily supplementation of AD vitamin 200-400 IU /day - " regular subgroup 0", 933 children were given by bolus doses of D vitamin forte 450 000 IU every three months during first year of life - "fortified subgroup 2", and 105 children given by bolus doses of D vitamin during winter, and continuous daily AD drops during summer - " mixed subgroup 1". D vitamin supplementation was done approximately 13 years before blood pressure study.

RESULTS: The mean systolic blood pressure was 110 mmHg, and mean diastolic one was 70 mmHg in all subgroups, regardless the mode of vitamin D supplementation. There were no statistic differences among subgroups, between girls/ boys, blood pressure levels were in normal limit. Although calculated daily doses of D2 vitamin during infancy exceeded RDA (200-400 IU) four to ten time, no difference in morbidity was found, concerning various chronic diseases (allergy, cardiovascular, renal, etc.). These results are in full accordance to recent knowledge of higher requirement and safety limit during vitamin D application.

CONCLUSION: The mode of D vitamin prophylaxis during infancy (pulse or daily application) has no influence to blood pressure level in early adolescence. No adverse effects have been found despite that the calculated daily dose was exceeded from three to ten times the recommended daily allowance....
