Plant protein drink may shield aging Hearts—A trial puts it to the test
NCT ID NCT04923555
First seen Aug 05, 2026 · Last updated Aug 06, 2026 · Updated 1 time
Summary
This trial tests whether a single yogurt drink made from vegetable proteins rich in leucine, cysteine, and arginine can improve blood vessel function and reduce inflammation in older adults with cardiometabolic risk. Participants, aged 65 and older, will consume either the vegetable protein drink or an animal protein version, and researchers will measure how well their blood vessels dilate before and after. The goal is to see if plant-based proteins can be a heart-healthy alternative to animal proteins for aging populations.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- A yogurt drink made with vegetable proteins rich in leucine, cysteine, and arginine
- What this could lead to
- If effective, this could support recommendations to replace animal proteins with plant-based options in older adults without harming heart health, and possibly improve vascular function.
- What could go wrong
- This is a small, early-stage trial with only 33 participants, so results may not apply broadly. The drink is tested only once, so any effects might be short-lived and not reflect long-term benefits.
