Filter by:The main objective of this study is to study the bioavailability and kinetics of acute Aronia Melanocarpa supplementation in healthy young (18-35 years) and older adults (55-75 years) adults. During the test day, participants will ingest a drink consisting of Aronia Melanocarpa extract (AME). The bioavailability and kinetics of AME will be assessed via frequent blood sampling, urine collection, and faecal sampling, in which AME and metabolite profiles will be quantified.
The purpose of this study is to To study the blood bioavailability of a sustained-release β-alanine granulated supplement of two different doses (10 g and 20 g).
This study is intended to evaluate how significantly a proprietary curcumin formulation (curQ+®) results in greater bioavailability compared to 95% curcumin extract over a 6-hour time period following a single oral dose in healthy men & women.
The aim is to determine the bioavailability of the polyphenol fraction form a commercially available hemp hull fiber at two different amounts in generally healthy adults. Additional objectives include determining specific metabolites produced over a 24 to 48-hour period following the hemp fiber consumption. Subjects will consume a study pudding that will be used to deliver a low and a high dose fiber product. Blood samples will be collected to measure background levels of metabolites. At day 0 participants will consume a low dose study product and day 6 the high dose study product and provide blood samples over an 8 hr period after study product consumption, to be followed by a 24 hr blood sample and 48 hr blood sample. Additionally following the low / high dose study product 24 and 48 h urine samples will be collected.
Open label study to assess relative bioavailability of filgotinib oral mini-tablet versus oral tablet formulation and effect of food on the mini-tablet formulation.
This is a single centre, open-label, randomised, single dose, 3-way crossover comparative (PK) and bioavailability study in healthy male subjects comparing a 200 mg Sorafenib (Nexavar®) reference tablet (Regimen A) to XS005 Sorafenib Capsule A, 2 x 50 mg (Regimen B) and XS005 Sorafenib Tablet A,100 mg (Regimen C) formulation. It is planned to enroll 15 subjects who will receive single oral doses of investigational medicinal product (IMP) across 3 treatment periods.
In vitro studies found supplemental levels of iron and zinc to inhibit the micellization and cellular uptake of β-carotene. Here, we investigated this in vivo, in a double-blind 3-arm crossover human trial. Healthy males (n=6) ingested, with breakfast, a single dose of 15 mg β-carotene in combination with either a placebo, 25 mg iron or 30 mg zinc capsule. Blood samples were collected at baseline and hourly for 10 hours. The triacylglycerol-rich fraction (TRF) was analysed for concentrations of β-carotene and plasma for β-carotene, retinol, triacylglycerols, LDL- and HDL-cholesterol.
Results from several clinical studies show that orally administered melatonin has low bioavailability and a very short half-life. Phenyl capsaicin, a synthetic analogue of capsaicin, might increase its bioavailability by inhibiting the enzymes involved in its hepatic metabolism. Thus, the hypothesis of the present study is that the administration of melatonin supplement with phenyl capsaicin presents greater bioavailability than a melatonin supplement that does not contain phenyl capsaicin.
In the current study, the OAT fibril - Fe SA (Fe-oat 1) and OAT fibril - Fe NaOH (Fe-oat 2) will both be studied in vivo, alone are oat fibril powder add iron supplement is soluble in water and oat fibril powder add iron supplement is soluble in water in a food matrix (acai puree and honey) to assess their promise as Fe food fortificants. This first in human study to bioavailability assessment and adverse effect of the OAT fibril - Fe SA (Fe-oat 1), OAT fibril - Fe NaOH (Fe-oat 2) and in a food matrix to assess their promise as Fe food fortificants. This study will be conducted with the following objectives. 1. To conduct a stable Fe isotope study to evaluate the bioavailability of OAT-Fe formulated using two reducing agents (Fe-oat 1 and Fe-oat-2) and compared to FeSO4. 2. To compare the performance of Fe-oat 1 and 2 in a food matrix containing Fe inhibitors, (acai puree and honey) in comparison to FeSO4 in a similar meal matrix.
To test how two weeks of curcumin supplementation would cross the blood brain barrier (BBB) and attach to amyloid beta proteins, to assess the feasibility (safety and bioavailability), and to explore the resulting abundance/composition of gut microbiota.
