The deliberately conservative, all-evidence-backed starter stack — the "all-green" counterpoint to the maximalist regimens. Every item is a real, recommendable supplement with genuine human evidence; nothing gated or grey-market.
Documented, not endorsed. What Beginner longevity reports taking (as of 2026-06) — not medical advice, not a recommendation. We sell nothing; each item links to its independently evidence-graded card.
“Start” adds the 7 evidence-graded compounds to your own stack to edit — gated research compounds excluded. Not an endorsement.

Vitamin D3 + Vitamin K2 — A 2020 meta-analysis of 8 trials found vitamin K plus vitamin D slightly raised total bone density and lowered undercarboxylated osteocalcin. The trials used different vitamin K forms and doses, one of them high-dose MK-4 with alfacalcidol, an active vitamin D drug, so they are not direct evidence for ordinary vitamin D3 with a consumer dose of MK-7. No trial has shown that adding K2 to vitamin D prevents arterial calcification.
