Site transparency

Evidence & Kashrut Changelog

A running log of evidence updates, kosher certification changes, methodology additions, and product re-rankings. The site's premise is evidence currency and kashrut accuracy — this page makes both verifiable.

May 2026
Product images added to rankings

Added product images to 6 of 7 ranked supplements on the rankings page. NMN image pending manufacturer change. Images sourced from official brand photography.

Newsletter form repaired

Homepage email subscribe form was showing a fake confirmation without actually sending anything. Fixed to submit via Formspree. Apologies to anyone who thought they subscribed before this fix.

Evidence last reviewed dates added

Added "Evidence last reviewed: May 2026" timestamps to the rankings page, all kashrut guides, supplement guides, and testing pages. Site premise is evidence currency — dates should be visible.

Deep cross-linking with EvidenceBasedLongevity.co

Upgraded all cross-links to the parent site from generic homepage links to page-specific deep links. Rankings page now links to EBL's specific supplement category pages. EBL supplement pages link back to relevant KL kashrut guides and rankings.

GlyNAC added to rankings (#6)

Added GlyNAC (Glycine + NAC) to the supplement rankings at #6 Tier 2, based on Kumar et al. 2023 (J Gerontol, PMID 35975308). Thorne NAC carries OU/OK certification; kosher source verification on glycine fermentation substrate noted as priority for next audit.

April 2026
NutraBio NMN — OU certification confirmed

Confirmed NutraBio NMN currently holds OU certification on the active SKU. Cross-verified against OU's public database. Note: NMN brands frequently change formulations — verify current lot certification before purchasing.

Pesach kashrut guide expanded

Added kitniyot analysis for creatine (corn-derived synthesis pathway), NMN (fermentation substrate), and glycine (fermentation). Each carries a "verify with your rav" note given community variation on kitniyot derivatives. See Pesach guide →

Capsule shell auditor updated — 12 new SKUs

Added 12 new SKUs to the capsule shell auditor. Three previously listed as HPMC confirmed switched to bovine gelatin in new production runs: flagged with change date. Quarterly re-audit scheduled.

Vitamin D3 lanolin vs lichen comparison added

Added detailed lanolin vs. lichen comparison to the Vitamin D3 evidence card. Lichen-derived (Bluebonnet) confirmed pareve and OU certified. Lanolin-derived D3 pareve status documented as community-dependent — majority poskim permit, some require lichen. Updated ranking card accordingly.

March 2026
Site launched — 7 ranked supplements, 6 kashrut guides

KosherLongevity.com launched as a specialized kashrut-integrity vertical of EvidenceBasedLongevity.co. 7 supplements ranked by human RCT evidence and verified kosher certification. Kashrut section covering certification agencies, capsule shells, Pesach status, and Shabbat/Yom Tov device considerations.

REDUCE-IT and VITAL trial data verified

Omega-3 (REDUCE-IT, PMID 30415628) and Vitamin D3 (VITAL, PMID 31733345) evidence cards reviewed and graded. Both assigned Tier 1 / Grade A. Nordic Naturals and Bluebonnet kosher certifications confirmed against OU and OK registries.

Metformin B12 guide published

Published comprehensive Metformin + B12 depletion guide — the most common drug-nutrient interaction in the kosher longevity demographic given Metformin's prevalence in type 2 diabetics and anti-aging protocols. Includes kosher B12 form verification and capsule shell audit.
