Probiotic drink could turn back the clock on aging arteries
NCT ID NCT05296395
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a probiotic drink called Lp299v (found in GoodBelly StraightShot) can reverse age-related stiffening of blood vessels in healthy adults aged 50 to 99. The 20 participants will take the drink daily and have their blood vessel function measured. It is a small, early-stage trial to see if targeting gut bacteria can improve vascular health.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Lactobacillus Plantarum 299v (a probiotic) in a fermented oat drink
What this could lead to
If it works, this could point toward a simple dietary supplement to help keep blood vessels healthy as people age.
What could go wrong
This is a very small early study (20 people) with no placebo comparison yet. The effect may be small or not happen at all, and results may not apply to people with health conditions.
