About this trial
Protein consumption is essential for various physiological processes, with microalgae and plant proteins gaining increasing attention due to their health benefits. To better understand how different protein types and processing methods impact health outcomes, this study aims to analyse the metabolite changes in response to different protein sources.

Trial design
Crossover
Treatments tested in this trial
Bead-milled microalgae
Dietary supplementConsume a 400 mL drink containing 20 g protein equivalent of bead-milled microalgae
Non-bead-milled microalgae
Dietary supplementConsume a 400 mL drink containing 20 g protein equivalent of non-bead-milled microalgae
Whey protein isolate
Dietary supplementConsume a 400 mL drink containing 20 g protein equivalent of whey protein isolate
Soy protein isolate

Treatment groups
Trial outcomes
Primary outcomes
Changes in metabolites found in plasma (plasma metabolomics)
Targeted metabolomics profiling of plasma will be conducted using liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS)
Changes in metabolites found in urine (urinary metabolomics)
Targeted metabolomics profiling of urine will be conducted liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS)
Secondary outcomes
Appetite
The Appetite Visual Analogue Scale (VAS) questionnaire will be administered, with participants rating five appetite-related outcomes, i.e. desire to eat, hunger, fullness, satisfaction, and prospective food consumption. Each response will be measured on a 100-mm visual analogue scale and scored from 0 to 100, with higher scores indicate a greater intensity of the outcomes being assessed, i.e. greater desire to eat, greater hunger, greater fullness, greater satisfaction, or a greater perceived amount of food that could be consumed.
