Understanding Our Scientific Approach

The Efficacy Engine® is a revolutionary system that combines artificial intelligence with medical expertise to evaluate ingredients based on clinical evidence quality. Our grading system applies the same rigorous standards used for pharmaceutical medications to foods, supplements, and wellness products.

"From Grade A (Effective) to Grade F (Ineffective/Hazardous), every rating is backed by peer-reviewed clinical research, ensuring you make informed health decisions with confidence."

Our comprehensive evaluation considers study size, bias assessment, validity criteria, and consistency of outcomes across multiple clinical trials and meta-analyses. This ensures every recommendation is based on solid scientific evidence, not marketing claims.

Complete Grading Criteria

Our comprehensive six-grade system evaluates ingredients based on clinical evidence quality, study size, bias assessment, and consistency of outcomes.

A

Effective

This product has a very high level of reliable clinical evidence supporting its use for a specific indication. Evidence consistent with or equivalent to passing FDA review.

Multiple randomized clinical trials with hundreds to thousands of patients
Studies have low risk of bias and high validity
Evidence consistently shows POSITIVE outcomes without valid evidence to the contrary
B

Probably Effective

High level of reliable clinical evidence supporting its use. Multiple randomized clinical trials or meta-analysis including several hundred patients.

Studies have low risk of bias and high validity
Evidence consistently shows POSITIVE outcomes without significant valid evidence to the contrary
C

Marginally Effective

Some clinical evidence supporting its use; however, evidence is limited by quantity, quality, or contradictory findings.

One or more randomized trials or population-based studies
Low to moderate risk of bias
Evidence shows POSITIVE outcomes, with valid positive evidence outweighing contrary evidence
D

Possibly Ineffective

Some clinical evidence showing ineffectiveness for a specific indication; however, evidence is limited by quantity, quality, or contradictory findings.

One or more trials or studies with low to moderate bias risk
Evidence shows NEGATIVE outcomes without substantial contrary evidence
E

Probably Ineffective

Very high level of reliable clinical evidence showing ineffectiveness. Multiple randomized clinical trials or meta-analysis with several hundred patients.

Studies have low risk of bias and high validity
Evidence consistently shows NEGATIVE outcomes without significant valid evidence to the contrary
F

Ineffective / Hazardous

Very high level of reliable clinical evidence showing ineffectiveness or potential harm. Multiple randomized trials with hundreds to thousands of patients.

Studies have low risk of bias and high validity
Evidence consistently shows NEGATIVE outcomes without any valid evidence to the contrary

What "Efficacy" Really Means

"The extent to which a specific intervention, procedure, regimen, or service produces a beneficial result under ideal conditions"

Medical Definition of Efficacy

The word "efficacy" is a term most commonly used in medicine with a specific meaning. It applies to prescription pharmaceuticals where claims are supported by extensive clinical studies that must pass FDA scrutiny before being certified as legitimate.

In a world of products unregulated by the FDA, the word has equal meaning but potentially greater importance as to the legitimacy of product claims. Food for Health is committed to providing unbiased product recommendations whose ingredients have efficacy and are legitimately effective.

Even in pharmacology, prescription medications may not have equal effectiveness from person to person. We rely upon physicians, pharmacists, and scientists to deliver the most likely results. Each person has their unique chemistry that affects the efficacy of pharmaceutical medications or the products we recommend.

Our Commitment to You
