Beet Extract
Also known as: Beta vulgaris extract, beetroot extract, red beet extract, betalain extract
Effective Dosage
No established dose (insufficient research data)
What the Science Says
Beet extract comes from the red beet plant and contains bioactive compounds called betalains, natural nitrates, and glucosylceramides. Lab and animal research suggests these compounds may have antioxidant properties and could support skin barrier function after UV damage. However, no clinical trials in the provided research confirm these effects translate meaningfully to humans taking beet extract as a supplement.
What It Doesn't Do
Not proven to boost athletic performance in humans based on these studies. No clinical evidence it lowers blood pressure or improves exercise endurance. Don't assume 'natural nitrates' from beet are automatically safer or more effective than other sources. No proven detox effect. Not a proven skin care treatment for humans.

Absorption & Bioavailability
Unknown — no human pharmacokinetic or absorption data in the provided studies
Red Flags to Watch For
- A case report links a supplement containing beet extract to severe drug-induced autoimmune hepatitis and eventual liver cirrhosis — though the product contained multiple ingredients, making beet extract's specific role unclear
- Zero clinical trials in the provided research base — all human benefit claims rest on animal studies or food science reviews
- Widely used in 1,000+ registered supplement products despite very limited clinical evidence of efficacy
- Betalain stability and bioactivity depend heavily on extraction method and formulation — product quality varies enormously
- Often combined with other ingredients in supplements, making it impossible to attribute any effect specifically to beet extract
