Our 5-Step Review Process
Every product review on QuizMyWellness follows the same structured process regardless of niche, affiliate commission, or manufacturer relationship. No steps are skipped, and the order is not flexible, the rating emerges from the process, not the other way round.
Obtain and verify the full ingredient label
We start with the supplement facts panel, not the manufacturer's marketing page. Every ingredient, every dose, every form is recorded before any other research begins. Where dose information is not available on the label (proprietary blends), this is flagged as a negative in the transparency evaluation and the rating is adjusted accordingly. We do not rely on manufacturer-supplied ingredient information without cross-referencing the actual product label.
Evaluate each ingredient individually
Each ingredient is assessed for: (a) the form used and its bioavailability implications, (b) the dose relative to amounts used in published research or traditional therapeutic practice, (c) the mechanism of action and its relevance to the product's stated purpose, and (d) any known contraindications, medication interactions, or population-specific cautions. This step uses the research sources listed in the Sources section below.
Assess formula cohesion
Individual ingredients are evaluated together as a formula: Do they address complementary mechanisms or do several ingredients duplicate each other's actions? Are there synergistic pairings that enhance the formula's effectiveness (e.g. Bromelain enhancing Quercetin absorption)? Are there antagonistic combinations or unnecessary fillers? Does the formula's overall scope match its stated purpose?
Apply niche-specific compliance review
All health claims, including implied claims from ingredient selection and naming, are reviewed against the applicable compliance standard for the niche (see Compliance Standards section). Blood Sugar Support and Nerve Comfort reviews undergo the most stringent compliance review given their proximity to diagnosed medical conditions. Any claim that could be construed as therapeutic for a disease state is rewritten before publication.
Apply rating and write the verdict
The star rating is assigned using the framework below. The verdict is written to reflect the ingredient analysis, not the product's marketing. The "Who This Suits" and "Who This Doesn't Suit" sections are written after all previous steps are complete, ensuring they reflect the actual formula characteristics rather than a predetermined narrative.
How Star Ratings Are Determined
All products reviewed on QuizMyWellness are products we are willing to recommend to generally healthy adults seeking support in the relevant niche. We do not publish reviews of products we consider inadequate, if a product fails the ingredient evaluation, we do not cover it. Within the range of products we cover, star ratings distinguish relative quality across five weighted factors.
| Rating | What It Means |
|---|---|
| ★★★★★ 4.9–5.0 | Exceptional formula, ingredients at research-aligned doses in optimal bioavailable forms, covering the niche's most important mechanisms comprehensively, with outstanding guarantee and manufacturing credentials. Rare. |
| ★★★★★ 4.7–4.8 | Very strong formula with at least one genuine formula distinction from competitors, a unique ingredient, a higher meaningful dose, a specific standardisation level, or coverage of a mechanism others miss. Recommended without significant reservation. |
| ★★★★½ 4.5–4.6 | Solid formula with clear positioning and a specific strength. May have a narrower mechanism range or lack one or two ingredients present in higher-rated competitors. Recommended for the specific audience identified in Who This Suits. |
| ★★★★ 4.0–4.4 | Acceptable formula with meaningful quality but notable gaps, potentially lower-bioavailability forms, insufficient doses on key ingredients, or missing mechanisms that higher-rated products cover. Appropriate for specific use cases only. |
| Below 4.0 | Not covered on this site. Products below this threshold do not meet our minimum standard for recommending to readers. |
The Five Weighted Rating Factors
Ingredient Quality and Dosing
Are active ingredients in their most bioavailable forms (Methylcobalamin vs cyanocobalamin, Magnesium Glycinate vs oxide)? Are doses at or near research-used levels? Are botanical extracts standardised to their active compounds?
Formula Comprehensiveness
Does the formula address the niche's key mechanisms or only a subset? Are mechanisms complementary rather than redundant? Does the ingredient selection reflect the current state of knowledge in the relevant nutritional or botanical field?
Formula Transparency
Are all doses disclosed? Are ingredient forms specified? Is the product free of proprietary blends that obscure individual ingredient amounts? Does the label match the marketing claims?
Manufacturing and Guarantee
Is the product GMP-certified? Made in a regulated facility? Does the money-back guarantee reflect manufacturer confidence in the product (60 days minimum; 90–180 days is better)? Are third-party testing results available?
Value and Accessibility
Is the per-day cost reasonable relative to ingredient quality? Is pricing transparent without hidden subscription commitments? Is the product available to the target audience without unreasonable barriers?
Ingredient Evaluation Framework
Ingredient evaluation is the most technically demanding part of our review process. The following criteria are applied to every active ingredient in every formula we review.
Form Assessment
Many vitamins and minerals come in multiple chemical forms with significantly different bioavailability. We evaluate whether the form chosen optimises delivery to the target tissue:
- B12: Methylcobalamin (neurologically active, preferred) vs cyanocobalamin (requires conversion, contains cyanide molecule)
- B1: Benfotiamine (fat-soluble, crosses cell membranes) vs thiamine HCl (water-soluble, lower intracellular penetration)
- B6: Pyridoxal-5-Phosphate (active coenzyme form) vs pyridoxine (requires hepatic conversion; high doses of pyridoxine over extended periods have been associated with peripheral neuropathy)
- B9: Methylfolate (active form, bypasses MTHFR enzyme requirement) vs folic acid (synthetic form requiring MTHFR conversion, problematic for 40%+ of population with MTHFR variants)
- Magnesium: Glycinate or Malate (high bioavailability, gentle GI profile) vs Oxide (very low bioavailability, strong laxative effect at dose)
- Zinc: Glycinate or Picolinate (high absorption) vs Oxide or Sulfate (lower bioavailability)
- Chromium: Picolinate (most researched, high bioavailability) vs Chloride or Polynicotinate
Dose Assessment
We compare ingredient doses against the amounts used in published clinical research where available, and against traditional therapeutic dose ranges for botanical herbs. A product that includes an ingredient at 1/10th the dose used in research gets credit for the ingredient's presence but not for its mechanism's full potential contribution. This dose-versus-research-standard comparison is one of the primary ways we distinguish strong formulas from formulas that use low doses of impressive-sounding ingredients for label appeal.
Standardisation Assessment (for botanical extracts)
Botanical herbs must be standardised to their active compounds to ensure consistent potency. An unstandardised herb powder may deliver unpredictable amounts of the compounds responsible for its therapeutic action. We assess:
- Whether the extract is standardised (e.g. "Turmeric Extract (95% curcumin)" vs "Turmeric Powder")
- Whether the standardisation percentage is disclosed
- Whether the active compound percentage is appropriate (e.g. 95% curcumin is the pharmaceutical standard for Turmeric; lower standardisations may reflect lower-grade extracts)
- Whether the stated active compound is the one supported by research for the product's purpose
Compliance Standards by Niche
Supplement marketing operates under strict legal limits set by the FTC, the FDA, and equivalent bodies in other jurisdictions. The core principle is that dietary supplements cannot claim to diagnose, treat, cure, or prevent any disease. All claims must relate to structure/function, how the supplement supports the normal function of a body system in a healthy person.
We apply a tiered compliance framework based on the proximity of each niche's topics to diagnosable medical conditions:
| Niche | Risk Level | Key Compliance Requirements |
|---|---|---|
| Men's Vitality | Lower | No erectile dysfunction treatment claims. Vocabulary: "supports healthy circulation," "supports energy and vitality", not "treats ED." |
| Weight Management | Lower | No obesity treatment claims. Vocabulary: "supports healthy weight management", not "causes weight loss" or "treats obesity." |
| Healthy Skin Aging | Lower | No cosmetic surgery equivalent claims. Vocabulary: "supports skin elasticity", not "eliminates wrinkles" or "reverses aging." |
| Vision Support | Moderate | No disease treatment claims (macular degeneration, glaucoma). Vocabulary: "supports healthy macular function", not "prevents AMD." |
| Lymphatic Wellness | Moderate | No lymphedema or cancer treatment claims. Vocabulary: "supports healthy lymphatic flow", not "treats lymphedema." |
| Nerve Comfort Support | High | No neuropathy or sciatica treatment claims. Prominent medical notice on every page. No "treats," "heals," or "cures" nerve conditions. Drug interaction warnings for specific ingredients. |
| Blood Sugar Support | Highest | No diabetes treatment or medication comparison claims. Explicit statement that products are for healthy adults with blood sugar already within normal range only. Berberine-Metformin mechanism comparison accompanied by explicit "not a diabetes medication" disclaimer. Drug interaction warnings mandatory for every page. |
Language We Never Use
- "Lowers blood sugar" or "controls blood sugar", implies medical management of a disease
- "Treats neuropathy" or "treats sciatica", implies medical treatment of a diagnosed condition
- "Reverses" or "cures" any condition
- "As effective as [drug name]", implies medical equivalence to prescription medication
- "Safe for diabetics" without a healthcare provider consultation qualifier
- Any language that could reasonably encourage a person with a diagnosed condition to use a supplement instead of prescribed medical treatment
Language We Use for Health-Sensitive Niches
- "Supports healthy blood sugar levels already within the normal range", accurate scope
- "Supports healthy glucose metabolism in generally healthy adults", accurate audience
- "Supports nerve comfort in generally healthy adults", nerve function, not disease treatment
- "Not a treatment for [condition], consult your doctor", explicit medical disclaimer
- "People taking [medication] must consult their doctor before use", specific interaction warnings
Affiliate Relationships and Editorial Independence
QuizMyWellness earns commissions when readers click affiliate links and make purchases. This is our sole revenue source. We are fully transparent about this relationship and want to be equally transparent about how we prevent it from compromising our editorial standards.
Our Specific Independence Commitments
Ratings are set before affiliate relationships are confirmed. A product's ingredient evaluation and preliminary rating are completed before we confirm an affiliate arrangement for that product. We do not adjust ratings after seeing commission structures.
We will not promote a product we consider inadequate. If a product's formula does not meet our minimum standard (4.0/5), we do not review it, regardless of affiliate commission offered.
Commission rates do not influence ranking. Our Top Pick for each niche is the product with the strongest formula by our methodology, not the product offering the highest commission. Where our Top Pick carries a lower commission than a competitor, the Top Pick retains its ranking.
Negative findings are published. If an ingredient in a product has a significant drug interaction risk, a dose that falls short of research-used levels, or a contraindication for a meaningful population, we publish that finding in the review, it is not omitted because it may reduce conversion.
Research Sources We Use
The following sources are consulted during ingredient evaluation. We draw on primary research where available and authoritative secondary sources for traditional use and safety information.
Where we cite research findings in a review, we describe the finding accurately without overclaiming its significance. "Research has explored X for Y with positive findings" is accurate when positive RCTs exist but the evidence is not definitive. "Research confirms X causes Y" is not a standard we use for dietary supplement ingredients unless the evidence base is exceptionally robust. We err on the side of cautious representation of evidence strength.
How We Update Reviews
Reviews are updated in three circumstances:
- Annual review cycle: Every published review is re-evaluated at least once per year. The "Last Updated" date in the meta information reflects the most recent review date.
- Formula change: If a manufacturer changes the formula of a reviewed product, adding or removing ingredients, changing doses or forms, the review is updated within 30 days of the change being confirmed. If the change materially affects the rating, the rating is adjusted accordingly and the change is noted in the review.
- Significant new research: If a major systematic review, meta-analysis, or RCT substantially changes the evidence base for a key ingredient in a reviewed product, the review is updated to reflect the new evidence.
Corrections Policy
We correct factual errors, incorrect ingredient doses, incorrect mechanism descriptions, incorrect safety information, as quickly as possible after they are identified and verified. We do not quietly edit content; corrections are noted with a date at the top of the relevant section.
If you believe any information on this site is factually incorrect, please email us at [email protected] with the specific claim, the URL, and the source supporting the correction. We investigate all correction requests and respond within 5 business days. We take accuracy seriously, a factual error in a health context is not a minor matter.
