WeightCited is an evidence-based platform that evaluates supplements and natural compounds for weight management. We analyze peer-reviewed clinical research to help consumers understand which ingredients have scientific support for various weight-related goals.

How does WeightCited evaluate supplements for weight management?

We review randomized controlled trials, systematic reviews, and meta-analyses published in peer-reviewed journals. Each ingredient is assessed for its level of evidence, typical dosages studied, and reported outcomes related to weight management.

Are the supplements on WeightCited FDA-approved for weight loss?

Dietary supplements are not FDA-approved to treat, cure, or prevent any disease, including obesity. The FDA regulates supplements under different rules than pharmaceutical drugs. WeightCited presents published research findings, not medical recommendations.

Can I use WeightCited to replace my doctor's advice?

No. WeightCited is an educational resource and should not replace professional medical advice. Always consult a qualified healthcare provider before starting any supplement regimen, especially if you have underlying health conditions or take medications.

Is WeightCited free to use?

Yes, WeightCited provides free access to evidence-based information about weight management supplements. Our goal is to make peer-reviewed research accessible to consumers seeking reliable information about dietary supplements.

Evidence Grading System

Every supplement claim on this site is graded on an A–D scale based on peer-reviewed clinical research from PubMed. Our algorithm evaluates study design (RCTs rank highest), consistency of results, sample sizes, and the overall body of evidence. No manufacturer sponsorship influences our grades.

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.
