Official Trial Title
BEET root juice to reverse functional impairment in PAD: The BEET PAD Trial
Study Description

The department of Kinesiology seeks adults ages 50 and older with peripheral artery disease (PAD) for a research study. The purpose of the study is to determine the effects of beetroot juice on walking ability in people with blockages in their leg arteries. Beetroot juice is made from beets and early evidence suggests drinking beetroot juice may improve blood flow to the legs and leg muscle function.

You may be eligible for this study if:
- You are 50 years and older
- Have been diagnosed with peripheral artery disease (PAD)
- You get pain, discomfort, or other symptoms when you walk.
- Are willing to drink two small bottles of beetroot juice twice daily for 4.5 months

The study involves baseline testing consisting of testing for blockages in the leg arteries (ankle brachial index), questionnaires, walking and balance tests, height and weight, MRI, blood draw, and microbiome sample (tongue swab). You will be asked to drink the study beverage twice daily for 4.5 months and return for follow-up testing.

Study-related testing and supplementation are provided at no cost.


$50 after completing final follow-up. Up to $110 reimbursement for travel costs.
