Randomized Controlled Trial Clinical Trial
Glycerophosphocholine enhances growth hormone secretion and fat oxidation in young adults.
α-Glycerophosphocholine (GPC) is a putative acetylcholine precursor that potentially increases growth hormone secretion through the action of acetylcholine-stimulated catecholamine. The aim of this study was to investigate acute physiologic responses to a single intake of GPC. ⋯ These findings suggest that a single dose of GPC increases growth hormone secretion and hepatic fat oxidation, with concomitant increases in choline levels, in young adults.

Randomized Controlled Trial Comparative Study Clinical Trial
Digestive and physiologic effects of a wheat bran extract, arabino-xylan-oligosaccharide, in breakfast cereal.
We assessed whether a wheat bran extract containing arabino-xylan-oligosaccharide (AXOS) elicited a prebiotic effect and influenced other physiologic parameters when consumed in ready-to-eat cereal at two dose levels. ⋯ These results indicate that AXOS has prebiotic properties, selectively increasing fecal bifidobacteria, and increases postprandial ferulic acid concentrations in a dose-dependent manner in healthy men and women.
