18 基于循证研究的健康状况与补充剂信息

Explore health conditions with evidence-graded supplement recommendations. Each condition page ranks ingredients by the strength of clinical research supporting them.

How We Grade Evidence

每个健康状况页面按临床证据强度对补充剂成分进行排序。以下是各等级的含义：

A

Strong Evidence

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

B

Good Evidence

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

C

Some Evidence

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

D

Very Early Research

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