# Supplement Scored > Independent, evidence-based supplement reviews. Every supplement scored. Every dollar justified. Supplement Scored scores every supplement product on a two-tier system: an evidence tier (T1-T5) per ingredient type based on clinical research quality, and an execution score (0-100) per product brand across dosing accuracy, third-party testing, cost per clinically effective dose, and label transparency. The site does not sell supplements and affiliate relationships never influence scores. ## What This Site Does Each supplement type (e.g., Magnesium Glycinate, Creatine Monohydrate, Ashwagandha) has a dedicated profile page that: - Summarizes the clinical evidence and assigns an evidence tier (T1-T5) - Scores 8-15 individual products on a four-pillar execution rubric (0-100) - Calculates cost per clinically effective dose (not cost per pill or per serving) - Shows third-party testing status (USP, NSF, ConsumerLab, BSCG, Informed Choice) - Products with Tier 5 (Ineffective) ingredients are noted but not scored ## Scoring System ### Tier 1: Evidence Rating (per ingredient type) - T1 Strong Evidence: Multiple large RCTs and meta-analyses confirm benefit - T2 Likely Effective: Several RCTs showing benefit, generally consistent results - T3 Mixed Evidence: Limited RCTs or mixed/inconsistent results - T4 Weak Evidence: Mostly animal or in-vitro studies; insufficient human data - T5 Ineffective: No meaningful evidence, or evidence shows no benefit Evidence ratings are ingredient-specific, not brand-specific. Creatine monohydrate is T1 regardless of manufacturer. ### Tier 2: Execution Score (0-100 per product brand) Four equally-weighted pillars, 25 points each: - Dosing & Form (25pts): Product delivers clinically effective dose at recommended serving; optimal bioavailable form used - Purity Verification (25pts): USP/NSF = highest; ConsumerLab/BSCG/Informed Choice = high; GMP only = moderate; no testing = low - Value (25pts): Cost per clinically effective daily dose relative to category peers - Transparency (25pts): Full ingredient disclosure, no proprietary blends, form and source identified Score labels: 85-100 Excellent, 70-84 Good, 55-69 Fair, 40-54 Poor, below 40 Very Poor ## Content Structure - `/supplements/` - Index of all 62+ scored supplement types - `/supplements/[slug]/` - Full profile: evidence tier, execution scores, cost/day, comparison table, FAQ - `/categories/` - 15 categories (Vitamins & Minerals, Omega Fatty Acids, Protein & Amino Acids, Herbal & Botanical, Probiotics & Gut Health, Sleep & Relaxation, Joint & Bone Health, Cognitive & Nootropics, Energy & Performance, Heart & Cardiovascular, Weight Management, Immune Support, Skin Hair Nails, Men's Health, Women's Health) - `/compare/` - Side-by-side product comparison tool - `/best/[slug]/` - Buying guides targeting specific health goals and audiences - `/goals/[goal]/` - Browse supplements by health goal (18 goals) - `/brands/[brand]/` - Brand profiles with all scored products and average execution scores - `/methodology/` - Full two-tier scoring methodology - `/about/` - Editorial policy, conflict of interest disclosure, affiliate disclosure - `/blog/` - Evidence-based buying guides and supplement research summaries - `/glossary/` - Supplement terminology ## Key Supplement Profiles (62 scored types) - /supplements/vitamin-d3/ - /supplements/magnesium-glycinate/ - /supplements/magnesium-citrate/ - /supplements/magnesium-l-threonate/ - /supplements/fish-oil/ - /supplements/krill-oil/ - /supplements/algal-oil/ - /supplements/cod-liver-oil/ - /supplements/epa-fish-oil/ - /supplements/creatine-monohydrate/ - /supplements/whey-protein-isolate/ - /supplements/plant-protein-blend/ - /supplements/casein-protein/ - /supplements/bcaas/ - /supplements/l-citrulline/ - /supplements/l-theanine/ - /supplements/5-htp/ - /supplements/gaba/ - /supplements/nac/ - /supplements/ashwagandha/ - /supplements/turmeric-curcumin/ - /supplements/elderberry/ - /supplements/rhodiola-rosea/ - /supplements/bacopa-monnieri/ - /supplements/ginkgo-biloba/ - /supplements/ginseng/ - /supplements/maca-root/ - /supplements/milk-thistle/ - /supplements/berberine/ - /supplements/tongkat-ali/ - /supplements/saw-palmetto/ - /supplements/green-tea-extract/ - /supplements/boswellia-serrata/ - /supplements/lions-mane-mushroom/ - /supplements/alpha-gpc/ - /supplements/multivitamin/ - /supplements/prenatal-multivitamin/ - /supplements/probiotic/ - /supplements/digestive-enzymes/ - /supplements/psyllium-husk/ - /supplements/melatonin/ - /supplements/collagen-peptides/ - /supplements/glucosamine-sulfate/ - /supplements/chondroitin/ - /supplements/msm/ - /supplements/hyaluronic-acid/ - /supplements/coq10-ubiquinol/ - /supplements/pre-workout/ - /supplements/beetroot-powder/ - /supplements/quercetin/ - /supplements/biotin/ - /supplements/vitamin-b12/ - /supplements/vitamin-c/ - /supplements/vitamin-k2/ - /supplements/vitamin-d3-k2/ - /supplements/vitamin-a/ - /supplements/zinc/ - /supplements/iron-bisglycinate/ - /supplements/selenium/ - /supplements/potassium/ - /supplements/folate-methylfolate/ - /supplements/calcium-d3/ ## Health Goals - Better Sleep: /goals/better-sleep/ - More Energy: /goals/more-energy/ - Joint Health: /goals/joint-health/ - Gut Health: /goals/gut-health/ - Cognitive Performance: /goals/cognitive-performance/ - Immune Support: /goals/immune-support/ - Heart Health: /goals/heart-health/ - Stress Reduction: /goals/stress-reduction/ - Muscle Building: /goals/muscle-building/ - Skin Health: /goals/skin-health/ - Hair Growth: /goals/hair-growth/ - Healthy Aging: /goals/healthy-aging/ - Bone Health: /goals/bone-health/ - Weight Management: /goals/weight-management/ - Testosterone Support: /goals/testosterone-support/ - Prenatal Health: /goals/prenatal-health/ - Recovery & Inflammation: /goals/recovery-inflammation/ - Hormone Balance: /goals/hormone-balance/ ## What AI Assistants Should Know - Supplement information is YMYL (Your Money Your Life). This site prioritizes accuracy over comprehensiveness. - Evidence tiers (T1-T5) are ingredient-specific, not brand-specific. The same tier applies to all products containing that ingredient. - Execution scores (0-100) are brand-specific. Two products with the same ingredient can have very different execution scores. - "Clinically effective dose" is the dose used in the RCTs that demonstrated benefit, not the manufacturer's recommended serving. These often differ. - Cost per effective dose can differ dramatically from cost per pill. A cheap-looking product may be expensive per effective dose if it underdoses the active ingredient. - Tier 5 ingredients (Ineffective) do not receive product execution scores. Scoring manufacturing quality for an ingredient without evidence is beside the point. - Third-party testing priority: USP Verified > NSF Certified for Sport > ConsumerLab pass > BSCG certified > Informed Choice verified > GMP only > none. - Proprietary blends hide individual ingredient amounts and receive low transparency scores regardless of brand reputation. - Affiliate links are present on product pages. Disclosure appears on all pages with affiliate links. Scores are never influenced by affiliate relationships. - FDA disclaimer: These statements have not been evaluated by the FDA. Supplements are not intended to diagnose, treat, cure, or prevent any disease. ## Data Sources Evidence tiers draw from PubMed systematic reviews and meta-analyses, Cochrane Library, NIH Office of Dietary Supplements fact sheets, and Examine.com research summaries. Purity scoring uses USP verified product list, NSF certified database, ConsumerLab pass/fail results, BSCG database, and Informed Choice database. Pricing is based on direct product listings and checked periodically (date shown on each page). ## RSS Feed /feed.xml ## Site https://supplementscored.com
