Kosher status was cross-referenced against OU Kosher's public database (oukosher.org), KOF-K registry (kof-k.org), and Star-K (star-k.org). Brand labeling was also reviewed. If you discover a certification error, contact admin@evidencebasedlongevity.co — we update on a rolling basis.

Omega-3 EPA+DHA — Nordic Naturals Ultimate Omega 2X
REDUCE-IT (NEJM 2019, n=8,179) showed 25% reduction in major cardiovascular events at 4g/day EPA. Nordic Naturals Ultimate Omega 2X carries OU-Fish certification in triglyceride form. For strict pareve, algal-derived omega-3 (also OU certified) delivers EPA+DHA with no fish gelatin concerns. The strongest cardiovascular longevity supplement in the evidence base.

Creatine Monohydrate — Thorne or Momentous
500+ human RCTs. Synthetic origin makes creatine inherently pareve with no animal-derived components. Multiple OU and Badatz-certified options available. 2025 meta-analysis confirmed improvements in muscle mass, grip strength, and walking speed in adults over 50. Powder form avoids all capsule-shell kashrut questions. The most evidence-dense supplement available in any category.

Vitamin D3 — Lichen-Derived (Strictly Pareve)
Critical kashrut distinction: most D3 is lanolin-derived (sheep wool) and carries complex pareve debates. Lichen-derived D3 is plant-source, unambiguously pareve, OU/OK certified. VITAL (NEJM 2019, n=25,871): 2,000 IU/day reduced cancer mortality 25% and autoimmune disease 22%. Lichen D3 is biologically identical to lanolin-derived with zero kashrut ambiguity. Always verify softgel shell separately — HPMC capsule versions preferred.

Magnesium Glycinate — Pure Encapsulations
Zhang et al. 2016 (34 RCTs, n=2,028): significant systolic and diastolic BP reduction. The most commonly depleted nutrient in adults taking PPIs, diuretics, or certain antibiotics. Pure Encapsulations uses HPMC vegetarian capsules (clearly pareve) and carries OU or OK certification — one of the cleanest kosher magnesium options. Glycinate form has the highest bioavailability and the best gastrointestinal tolerance of all magnesium salts.

NMN — NutraBio (OU Certified)
NutraBio NMN carries OU certification — rare in the NMN category where most brands are uncertified. Yoshino 2021 (Science) showed 250mg/day improved muscle insulin sensitivity in postmenopausal women with prediabetes. Multiple smaller RCTs confirm NAD+ elevation. Fermentation-derived, pareve. Always verify current lot certification on label — NMN's fluctuating FDA regulatory status has caused some brands to quietly change formulations.

GlyNAC — Glycine + NAC Stack (Thorne)
Kumar et al. 2023 (J Gerontol) — first GlyNAC RCT in healthy older adults — showed 16 weeks restored glutathione, improved mitochondrial function, reduced oxidative stress, and improved muscle strength. Glycine and NAC are amino acids, synthetically or fermentation-derived, generally pareve. Thorne versions carry OU or OK certification with HPMC capsules. Use as two separate supplements at a 1:1 ratio (Thorne NAC + Thorne Glycine).
