Our Editorial Standards
SupplementReview was founded on a single principle: health consumers deserve honest, evidence-based supplement analysis that prioritizes their wellbeing over affiliate commissions. Every review published on this site goes through the same rigorous process regardless of the product, vendor relationship, or affiliate potential.
Our reviews are written by Dr. Lillian Whalen, a general health practitioner and product specialist with over 15 years of clinical experience evaluating supplements. All content is reviewed for medical accuracy before publication. We do not accept payment from supplement manufacturers for positive reviews, and no vendor can purchase placement or influence our ratings.
Evidence-First
Every claim about an ingredient is backed by peer-reviewed research or clearly labeled as anecdotal.
Independently Written
Vendors do not preview, approve, or influence our editorial content before publication.
Regularly Updated
Reviews are refreshed whenever significant new research or customer feedback emerges.
The 6-Phase Review Methodology
Phase 1: Product Intake and Surface Analysis
We begin by analyzing the product landing page, supplement facts label, ingredient list, and marketing claims. We document the vendor, price, money-back guarantee terms, and manufacturing certifications at this stage. Products without transparent labels or with unverified proprietary blends are flagged for lower initial scores.
Phase 2: Ingredient-Level Research
Each ingredient is individually evaluated using peer-reviewed databases including PubMed, Springer Nature, and Frontiers in Dental Medicine. We assess the quality of clinical evidence (RCT weight > observational studies), the effective dose range, bioavailability, known interactions, and synergy with other ingredients in the formula. Ingredients are rated Strong, Moderate, or Weak evidence.
Phase 3: Formula Assessment
We evaluate the complete formula for synergy, dose adequacy, and transparency. Proprietary blends are scrutinized to determine whether key ingredients are clinically dosed. We assess whether the formula addresses the root cause of the health concern or merely masks symptoms. Formulas that combine multiple evidence-based ingredients at proper doses score highest.
Phase 4: Customer Review and Marketplace Analysis
We aggregate and analyze customer reviews from the vendor page and independent platforms. We look at the ratio of positive to negative reviews, common complaint themes (shipping, side effects, efficacy timelines), and the credibility of the review volume relative to the product age. Unusually high review counts for new products are flagged.
Phase 5: Rating and Verdict
Products are rated on a 1-to-5 scale across 6 criteria: (1) Ingredient Quality and Evidence, (2) Formula Transparency, (3) Manufacturing Quality, (4) Customer Satisfaction, (5) Value for Money, and (6) Vendor Reliability. The overall score is a weighted average. Products scoring below 3.5 are not recommended.
Phase 6: Continuous Monitoring
Reviews are revisited quarterly or whenever significant new information emerges. If a product formula changes, a product receives a wave of negative reviews, or new clinical evidence surfaces, the review is updated immediately and the update is noted with a timestamp.
Ingredient Research Criteria
We evaluate each ingredient against five research criteria before assigning an evidence strength rating:
Clinical Trial Evidence
The number and quality of randomized controlled trials (RCTs) involving humans. RCTs carry the highest weight in our evaluation.
Effective Dose Range
Whether the product delivers the ingredient at the dose used in successful clinical studies, or sub-clinically underdosed.
Bioavailability
Whether the form of the ingredient used in the product is actually absorbable and usable by the body. For example, magnesium oxide has poor bioavailability vs magnesium glycinate.
Mechanism of Action
Whether a plausible biological mechanism explains how the ingredient produces its claimed effect, and whether that mechanism is supported by research.
Safety Profile
Known side effects, contraindications, and drug interactions. Ingredients with strong safety profiles at effective doses are preferred.
Synergy with Formula
Whether the ingredient works better in combination with other ingredients in the formula, and whether the formula captures those synergistic effects.
Rating Criteria Explained
Highly Recommended
Exceptional product with strong clinical evidence, transparent dosing, high customer satisfaction, and fair pricing. These are the products we use personally and recommend to family.
Recommended
Solid product with meaningful evidence and genuine customer benefits. Minor limitations in formula design, dosing, or price keep it from the top tier.
Consider With Caveats
The product has merits but significant limitations. May be appropriate for specific use cases or budgets but is not a broadly recommended choice.
Not Recommended
Fundamental issues with evidence, transparency, formula design, or customer satisfaction make this product difficult to recommend for most consumers.
Avoid
Products with misleading claims, dangerous ingredients, predatory marketing, or overwhelmingly negative customer feedback.
Update Schedule and Freshness Policy
Supplement research evolves rapidly. New clinical trials, ingredient interactions, and product reformulations can change our assessment of any product. We maintain a strict freshness policy to ensure our reviews reflect the current state of evidence and product quality.
Quarterly Review Cycle
Every published review is automatically flagged for re-evaluation every 90 days, regardless of whether new information has surfaced.
Event-Driven Updates
We update reviews immediately when a product changes its formula, the vendor changes their guarantee policy, significant new clinical evidence emerges, or we receive credible reader feedback indicating our assessment may be outdated.
Formula Change Detection
We monitor ClickBank product pages and vendor landing pages for formula changes. Any change to the ingredient list or dosage automatically triggers an immediate re-review.
Update Transparency
Every review page displays a "Last Updated" date. When we update a review, we document what changed and why in the revision note at the top of the page.
Affiliate Disclosure and Editorial Independence
SupplementReview is supported by affiliate links. When you click a product link on our site and make a purchase, we may earn a commission from the vendor at no additional cost to you. This is clearly disclosed at the top of every review page and in our footer.
This is how we keep the site free and accessible to everyone. However, affiliate income never influences our editorial decisions. A product earns a positive review based solely on its merit. Our ratings and verdicts are determined by the same methodology regardless of the commission rate or vendor relationship.
SupplementReview is a commercial entity operated by LeadMetrics AI Private Limited. We participate in the ClickBank, Amazon Associates, and private affiliate programs. Any potential conflicts of interest are disclosed on the relevant pages.
