Brief summary
Pilot trial: 6-week single arm intervention. Healthy adults (male and female) consume Molkosan (fermented whey) twice a day (AM & PM).
Detailed description
Molkosan® is made from fresh organic whey using a special fermentation process involving lactic acid producing bacteria (L+ lactic acid 70g/L). The company, A.Vogel (Roggwil, Switzerland) will provide the product and we will collect biological samples for analysis in a proof of concept study design that will provide preliminary data for future larger studies.
Interventions
Twice daily (AM and PM) 20ml of fermented whey concentrate consumed diluted in 200ml water

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in microbiota activity | Baseline, day 21 and 42 | Faecal short-chain fatty acids, measured by gas chromatography |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in glucose tolerance (Oral glucose tolerance test (OGTT) | Baseline, day 21 and 42 | Six blood samples will be collected during the course of 3 hours (0, 30, 60, 90,120 and 180 min) using a cannulation after consuming 75 g of Polycal liquid (glucose load). Plasma glucose level and insulin are analysed as total area under the curve (AUC) and incremental AUC. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Energy intake | Baseline and day 14-18 | 4-day weighed food diary analysed for energy intake and macronutrient composition |
| Change in microbiota composition - 16s rRNA (ribosomal ribonucleic acid) sequencing | Baseline, day 21 and 42 | 16S rRNA extracted from fresh stool samples (\<16hrs) |
| Pulse | Screening, baseline and day 42 | Triplicate measurement, expressed as beats per minute |
| Blood pressure | Screening, baseline and day 42 | Repeated in triplicate, measured in mmHg |
