Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Examining the safety and tolerability of Lentil Protein Hydrolysate in healthy males and females whilst exploring the effects of a dose range on blood pressure control and vascular function and exercise performance

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The aim of this trial is to evaluate the safety and tolerability of a lentil protein hydrolysate (LPH) in healthy participants while exploring effects on blood pressure control, vascular function and exercise performance. The study will be conducted in men and women over 4 weeks.

Specifically, the study has three key objectives:

1. To determine the safety and tolerability of 500 - 2000mg of a novel plant-based supplement LPH) in healthy volunteers as assessed via AE reporting, changes in clinic blood pressure and supplementation induced orthostatic hypotension during a sit-to-stand challenge.
2. To explore the effects of 4-weeks of lentil protein hydrolysate supplementation on markers of vascular age and endothelial function, fatigue, quality of life, and grip strength.
3. To explore the effects of 4-weeks of LPH supplementation on markers of exercise performance, including cardiorespiratory fitness (VO2max) and substrate utilisation during sub-maximal, steady-state exercise. This trial incorporates a wearable device to measure physical activity, cardiac health, sleep metrics and heart rate variability.

Exclusion Criteria

* Subjects having a known allergy or hypersensitivity to any of the ingredients in the investigational products.
* Subjects with a history of alcohol and/or other drug abuse in the past year.
* Has performed strenuous exercise (rating of perceived exertion ≥ 13) ≤ 48 hours before laboratory visit (Borg, 1982).
* Consuming \>14 alcoholic drinks per week or \> 2 drinks/day in the 48 hours preceding a clinic visit.
* Active smokers, nicotine use or vaping
* Subjects suffering from a sleep disorder and/or who have a known history of (or was being treated for) clinical depression, eating disorder(s) or any other psychiatric condition(s) that might put the subject at risk and/or confounded the results of the study.
* Subjects with a history of being diagnosed with phenylketonuria or another disease affecting amino acid metabolism (i.e., maple syrup urine disease, etc.).
