In vivo and in vitro assessment of vitamin B6 bioavailability in humans

Creator:: Kabir, Gholamhossein
Abstract:: Bioavailability (BA) of vitamin B6 (B-6) from foods may be limited. The knowledge of the BA of B6 from food is important in that this would help to understand if the B6 present in the diet of individuals will meet the requirements for this vitamin. The purpose of this study...

Supplemental vitamin B-6 and endurance exercise effects on plasma catecholamines of trained male cyclists

Creator:: Young, Jennifer Charity
Abstract:: This study examined the effect of vitamin B-6 supplementation and exhaustive submaximal exercise on plasma catecholamine concentrations, and the relationship between plasma catecholamines and fuel use, heart rate and oxygen consumption. Five trained men (age= 18-35 years; V0₂max=53 ml 0₂/kg/min.) participated in two controlled dietary periods that were identical except...

Effect of altered carbohydrate diet, vitamin B-6 supplementation, and exercise on vitamin B-6 metabolism in trained and untrained women

Creator:: Walter, M. Carol
Abstract:: This investigation was designed to add to present understanding of vitamin B-6 (B6) metabolism during exercise. Ten women, 5 aerobically trained and 5 untrained, were fed 4 controlled diets: a moderate carbohydrate (49%) (MCHO) for 2 weeks, a high carbohydrate (63%) (HCHO) for one week, MCH0+B6 for 2 weeks, and...

Vitamin B₆ enrichment of wheat flour : stability and bioavailability

Creator:: Perera, Anne Doloras
Abstract:: This investigation consisted of two parts: A. stability, B. bioavailability of vitamin B₆ in wheat. Three variables; whole wheat flour (WHW), white flour (W) and W enriched with vitamin B₆ (WB₆) were tested. Stability of vitamin B₆ during bread making and storage of bread and flour was determined. Bread was...

Influence of controlled strenuous exercise on vitamin B-6 metabolism in man : effects of carbohydrate depletion-repletion diets and vitamin B-6 supplements

Creator:: Hatcher, Lauren Francis
Abstract:: Recent studies in men have shown plasma levels of vitamin B-6 and pyridoxal 5'-phosphate (PLP), the active form of vitamin B-6, to increase with exercise. It was hypothesized that muscle glycogen phosphorylase might be the source of these increases as this enzyme has been shown to increase with increasing vitamin...

Vitamin B-6 metabolism and status in young and middle-aged women

Creator:: Lee, Caroll Marie
Abstract:: To investigate the responses of healthy adult women to two levels of vitamin B-6, a seven week two-part experiment was conducted with five young adults and eight middle-aged subjects. During the four unsupplemented weeks, dietary vitamin B-6 was 2.3-2.4 mg/day. In the final three weeks, the same diet was supplemented...

The effect of exhaustive endurance exercise and vitamin B-6 supplementation on vitamin B-6 metabolism and growth hormone in men

Creator:: Dunton, Nancy J.
Abstract:: Trained male cyclists (6 in study 1, 5 in study 2) cycled to exhaustion (EXH) at 75% of VO₂ max twice; once in the non-supplemented (NS) state and once in the vitamin B-6 (B-6)(20 mg PN) supplemented (S) state. The diet contained 2.3 mg B-6 in study 1 and 1.9...

Effect of varying levels of vitamin B-6 intake on lymphocyte mitogenic response and vitamin B-6 concentration in human peripheral blood mononuclear cells

Creator:: Kwak, Ho-Kyung
Abstract:: Two studies were conducted to determine the effect of varying vitamin B-6 (B- 6) status on lymphocyte mitogenic response and pyridoxal 5'-phosphate (PLP) concentration in peripheral blood mononuclear cells (PBMC) in young women. In the first study, women were fed 1 mg/d for the first week and 1.5, 2.1 and...
