Vinegar Extract
Also known as: polyphenol-rich vinegar extract, VE, Zhenjiang aromatic vinegar extract, ginsam, aged vinegar extract
Effective Dosage
No established dose (insufficient research data)
What the Science Says
Vinegar extract is a concentrated source of polyphenols — plant compounds with antioxidant and anti-inflammatory properties — derived from fermented vinegar. Animal studies suggest it may help lower blood glucose, reduce liver inflammation, and support a healthier gut microbiome by shifting the balance of beneficial bacteria. The only human clinical trial tested a ginseng-based vinegar extract (ginsam) in 72 type 2 diabetic patients over 8 weeks and found modest but statistically significant reductions in HbA1c and fasting blood glucose at 1500 mg/day, with no serious side effects reported.
What It Doesn't Do
Not proven to treat or reverse diabetes in humans — the one human trial was small and short. No evidence it detoxifies your body or cleanses your liver in any meaningful clinical sense. Animal gut microbiota results don't automatically translate to humans. No evidence it prevents blood clots in people — the antithrombotic data comes from rats and lab dishes only. Don't expect dramatic weight loss or immune system overhauls; those claims have zero support from the provided studies.

Absorption & Bioavailability
Unknown — no human pharmacokinetic or absorption studies were provided. Cell and animal studies used the extract directly; how well polyphenols from vinegar extract absorb in humans is not established by the available data.
Red Flags to Watch For
- Almost all evidence comes from mouse and cell studies — human data is extremely limited (one small 8-week RCT with 72 participants)
- The one human trial tested 'ginsam,' a ginseng-based vinegar extract — results may not apply to other vinegar extract products on the market
- No long-term safety data in humans; unknown interactions with diabetes medications or blood thinners
- Antithrombotic (blood-thinning) effects seen in animals — people on anticoagulants should use caution
- 1000+ supplement products registered in NIH DSLD suggest widespread commercial use far outpacing the actual human evidence base
