MERHI ONE Evidence Rating

We rate evidence for a specific claim—not an ingredient in the abstract.

‘Magnesium has strong evidence’ is not a scientifically useful statement. The right question is whether magnesium, for a defined indication and population, is supported by strong, moderate, limited, insufficient, or negative evidence.

The unit of evaluationIntervention or marker → specific indication → population → outcome → evidence level

Strong evidence

Consistent, high-confidence support for the defined claim.

Moderate evidence

Meaningful support with relevant remaining uncertainty.

Limited evidence

Suggestive findings, but important limitations remain.

Insufficient evidence

The available research cannot support a reliable conclusion.

Benefit not demonstrated

Adequate evidence has not shown the claimed benefit.

Potential for harm

Evidence or safety signals indicate clinically relevant risk.

The MERHI ONE Library

A scientific library—not a feed of random posts.

Content is organized by enduring questions and updated as evidence changes. Relevant pages show publication and review dates, authorship, medical review, verifiable references, limitations, and an evidence rating when appropriate.

Clear separation of evidence, hypothesis, and controversy
Independent medical review before commercial release
