Bird's Nest Extract

The hardened saliva nest of swiftlets, one of the most expensive traditional tonics in Asia, sold for skin, immunity and cognition. Almost all supporting research is in cells and animals; the small amount of human data does not yet show a clinical benefit.

Evidence last reviewed: August 2026

What the science says

  • Metabolic and general health effects Limited evidence

    A 12-week double-blind randomized controlled metabolomics study of dietary edible bird's nest documented shifts in blood metabolite profiles. Changes in metabolites are not the same as a health outcome, and the trial was small.

  • Cognition and neuroprotection Limited evidence

    A 2026 systematic review of edible bird's nest and cognitive function covered animal studies only, reporting effects on memory tasks in rodents. No controlled human cognitive trial has been published.

  • Skin benefits Limited evidence

    A dermatology review of the potential cutaneous benefits of edible bird's nest found the rationale rests on sialic acid and epidermal growth factor content plus in vitro work. Human skin trials are essentially absent.

Dosage & safety

Studied doseTraditional use is roughly 3–5 g of dried nest stewed, or one 70 mL ready-to-drink bottle daily. No dose has been established in trials.
SafetyBird's nest is a recognised food allergen and has caused severe anaphylaxis, particularly in children in Southeast Asia. Products have historically been adulterated with nitrite-treated material and other fillers. Very expensive relative to any demonstrated benefit.
