Brief Summary

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

The goal of this randomized, double-blind, placebo-controlled, cross-over trial is to investigate the effects of beetroot-derived betalains on cardiovascular health, sleep and quality of life in healthy middle-aged individuals. The main question\[s\] it aims to answer are:

* Do betalains improve vascular function?
* Do betalains improve sleep?
* Do betalains improve quality of life?

Participants will be involved with the following:

* Consuming a daily betalain-rich or placebo capsule for a month
* Non-invasive cardiovascular measurements
* Wearing a fitness tracker for tracking physical activity and sleep
* Answering questionnaires regarding quality of life

Researchers will compare results between the intervention versus the placebo group to see if any of the study outcomes are significantly different.
