How We Grade Evidence

Mỗi trang tình trạng sức khỏe xếp hạng các thành phần thực phẩm chức năng theo mức độ mạnh yếu của bằng chứng lâm sàng. Dưới đây là ý nghĩa của từng xếp hạng:

Strong Evidence

Multiple randomized controlled trials (RCTs) or meta-analyses with consistent positive results and large sample sizes.

Good Evidence

At least one RCT with mostly consistent results across studies. Evidence suggests benefit but more research may be needed.

Some Evidence

Small studies or observational data with some positive signals. Promising but insufficient for strong recommendations.

Very Early Research

In vitro studies, case reports, or pilot studies only. Early-stage research that requires clinical validation.
