Elderberry

Also known as: Sambucus nigra, Black Elderberry, European Elder, American Elderberry, Sambucus nigra subsp. canadensis

Evidence under review. — Not yet rated

Antioxidant-rich berry with early evidence for immune support, gut health, and metabolic benefits.

What the Science Says

Elderberry is the dark purple fruit of the Sambucus nigra plant, packed with anthocyanins — natural pigments with antioxidant and anti-inflammatory properties. Early clinical trials suggest it may support immune function, improve gut microbiome diversity, and help with dry eye symptoms when combined with other nutrients. Animal and lab studies point to potential benefits for blood sugar regulation and cognitive health, though human evidence is still limited.

What It Doesn't Do

Not proven to cure or prevent colds or flu on its own. No strong human evidence it directly boosts cognition in healthy adults. The cognitive and metabolic benefits seen in animal studies haven't been confirmed in large human trials. Multi-ingredient products make it impossible to credit elderberry alone for any performance benefit.

Evidence-Based Benefits

Combined with lutein and zeaxanthin, elderberry extract improved immune status scores in a 20-day RCT.

One week of elderberry juice increased beneficial gut bacteria diversity in overweight adults.

Supporting studies (click to view on PubMed):

Elderberry polyphenols may improve insulin sensitivity and reduce liver fat via gut microbial metabolism in mice.

Absorption & Bioavailability

Unknown — anthocyanins from elderberry are metabolized by gut bacteria into active compounds (like 3-phenylpropionic acid), meaning benefits may depend heavily on your individual gut microbiome composition.

Red Flags to Watch For

  • Most human trials are small (under 120 participants) and short-term (1–8 weeks), limiting confidence in results
  • Many studies test elderberry as part of multi-ingredient blends, making it impossible to isolate elderberry's specific contribution
  • Raw or unripe elderberries contain cyanogenic glycosides and can cause nausea or vomiting — only processed/cooked forms are safe
  • Animal and lab findings (metabolic, cognitive) have not been replicated in large human RCTs
  • Products marketed for flu prevention often cite older studies not included in current evidence; verify claims against recent trials
