Berry and oat shakes tested as Heart-Health boosters
NCT ID NCT03620266
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether daily shakes made from bilberries and oats can lower LDL cholesterol and improve exercise capacity in people who have had a heart attack or have type 2 diabetes. 900 participants will drink either a bilberry shake, an oat shake, a combination shake, or a placebo shake twice a day for three months. The goal is to see if these simple dietary additions can provide extra heart protection on top of standard medications.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- bilberry and oat shakes
- What this could lead to
- If it works, this could offer a simple, safe dietary strategy to help manage cholesterol and inflammation in people with heart disease or diabetes.
- What could go wrong
- This is a mid-sized study, not a large final-stage trial. The effects may be small or not clinically meaningful, and the shakes are taken alongside standard medications, not replacing them.
