Which supplements have clinical evidence for chronic conditions? Which products deliver them without filler? And how do you build a stack that doesn't overlap. Doctor-reviewed. Independent. No affiliate links.
We analyze from both sides: from the condition to the effective supplement — and from the supplement to the clinical evidence.
Which compounds have clinical evidence for specific chronic conditions? Which products deliver them in the right dose and form? How do you build a stack without overlap?
What does the research say about a specific supplement? For which conditions is there data? Which product delivers it in the studied form — and what does the compound cost vs. the marketing?
Systematic analysis of the most important age-related chronic conditions. Focus on pathologies where long-term supplementation can make an evidence-based contribution.
Glaucoma, AMD (dry & wet), cataracts, ocular microcirculation, digital eye strain
Endothelial function, atherosclerosis, blood pressure, homocysteine, lipid profile, vascular elasticity
Cognitive aging, neuroinflammation, Alzheimer's prevention, mitochondrial dysfunction in CNS
Osteoarthritis, osteoporosis, collagen metabolism, chronic joint inflammation
Insulin resistance, type 2 diabetes prevention, visceral fat, blood sugar regulation
Age-related immune decline, chronic low-grade inflammation, senolytics
Individual analyses of specific compounds. Study landscape, dosage, bioavailability, product comparison, price transparency. Every compound becomes a scorecard.
Five levels of scientific evidence. Every compound is rated per indication individually. No marketing claims — only published research.
How focused is the product on its target indication? Products that pack in general vitamins receive a penalty — because informed supplementers risk duplication with their baseline stack.
What does the active ingredient cost vs. what does the marketing cost? We normalize to price per day per core compound. Because Quatrefolic® L-methylfolate costs the same whether it's in a €5 B-complex or a €97 "medical food."
Three pathomechanisms. Three specialized products. Zero overlap. Zero general-vitamin filler.
| Mechanism | Product | Core Compounds | Evidence | €/mo. |
|---|---|---|---|---|
| Macula & Retina | Life Extension MacuGuard + Astaxanthin | Lutein 10mg, Meso-Z + Z 4mg, Saffron 20mg, Astaxanthin 6mg | L4–L5 | ~€20 |

For comparison: Nutravision (Australia) costs ~€45/mo. with underdosed carotenoids. Ocufolin® forte costs ~€30/mo. and covers only the homocysteine pathway. PreserVision AREDS2 overlaps with every multivitamin. Full review with 9 products →
