A $60 Billion Industry With Almost No Oversight
Most consumers have no way to verify what is actually in the bottle. Star ratings measure marketing. Gabriel measures the product.
of supplements have never been independently tested for label accuracy
FDA supplement records including warning letters, recalls, and adverse events
spent by the FDA on pre-market supplement testing. Companies self-police.
Star ratings were never designed for health decisions
A supplement with 10,000 five-star reviews could contain heavy metals above safe limits, have an FDA warning letter, and deliver 30% less of the active ingredient than its label claims. The rating would never tell you.

Why this scored low:
50+ Quality Signals. One Score.
Gabriel answers the questions that matter about every supplement. Lab results, clinical research, regulatory records, manufacturing standards, and intelligence from holistic practitioners, distilled into a single 0-100 score.
Is this product clean?
Gabriel checks for heavy metals, contaminants, and whether the label matches what is actually in the bottle. Independent testing, not marketing claims.
Who made it and how?
Manufacturing standards, facility certifications, and production quality. Where the product comes from matters as much as what is in it.
Are the ingredients effective?
Bioavailable forms versus cheap alternatives. Whether each ingredient is in a form your body can actually absorb and use.
Is the dose real?
Gabriel compares every ingredient to published clinical research. If a study used 400mg and the product has 50mg, you will know.
Has anything gone wrong?
FDA warning letters, recalls, adverse events, and enforcement history. A clean record matters.
Do practitioners trust it?
Intelligence from 155,000+ holistic and root-cause practitioners. Naturopaths, functional medicine doctors, and integrative specialists who see patient outcomes every day.
Meets Gabriel's quality standards
Exceptional quality, strong practitioner backing
Top 1%. The highest standard in supplement quality
A Marketing Dose Is Not
a Therapeutic Dose
Gabriel compares every ingredient amount against published clinical research. If a study used 400mg and the product contains 50mg, you should know that before you buy.
Generic Magnesium 100mg
Magnesium oxide. 4% absorption rate. You absorb roughly 4mg of elemental magnesium per serving.
Practitioner Magnesium Glycinate 400mg
Magnesium glycinate. 80% absorption rate. A full therapeutic dose in a highly bioavailable form.
What Else Is In the Bottle
Gabriel rates every inactive ingredient in every supplement. A product can have excellent active ingredients and still contain fillers or colorants that deserve scrutiny.
Safe
Cellulose, rice flour, silicon dioxide. Well-studied excipients with no known safety concerns at supplement doses.
Caution
Carrageenan, magnesium stearate, maltodextrin. Some evidence of concern. Not necessarily harmful, but worth knowing about.
Avoid
Titanium dioxide, artificial colors (Red 40, Blue 1), BHT. Ingredients with documented safety concerns or restrictions in other countries.

That “Practitioner Brand” on Amazon?
Probably Not From the Brand.
Many professional supplement brands do not authorize Amazon sales. Unauthorized resellers list them anyway. No guarantee of proper storage, handling, or authenticity.
Sold by third-party resellers, not the brand
No cold-chain guarantee for probiotics and fish oils
Could be expired, improperly stored, or counterfeit
Brands explicitly warn against purchasing here
No dosing guidance or interaction screening
Returns mixed back into inventory
Direct from authorized distribution channels
Proper temperature-controlled storage and handling
Guaranteed authentic, unexpired product
Practitioner guidance on dosing and protocols
AI-powered interaction screening with your full stack
Often less expensive than reseller pricing
Xymogen, Standard Process, Designs for Health, Biotics Research, and dozens of professional brands explicitly state that products sold through unauthorized channels may be counterfeit, expired, or improperly handled. Gabriel connects you to their authorized distribution network.
