Dietitians Highlight Five Key Supplements for Longevity

Key points

• Dietitians recommend five specific supplements to support longevity.
• The advice emphasizes targeted supplementation rather than routine use for all.
• The recommendations align with recent findings that general supplements offer limited benefits for healthy adults.
• Consulting a clinician is advised before starting new supplements, especially for those on medications.

Background

In August 2026, a review of 84 studies indicated that routine vitamin and mineral supplements offer little protection against heart disease, cancer, or early death for generally healthy adults. The review emphasized that timing and absorption, rather than the clock, are crucial for effectiveness, and advised consulting clinicians before adding supplements, particularly for those with absorption issues or taking medications like metformin.

Why it matters

As the longevity industry grows, expert guidance on which supplements actually support healthspan is critical. This advice helps consumers navigate a crowded market by focusing on evidence-based recommendations from dietitians, rather than relying on unverified claims or routine supplementation that may offer no benefit or cause harm.

What to watch

Consumers should consult healthcare providers before starting any new supplement regimen. Future research may further clarify the specific benefits and risks of these five supplements for different populations, particularly those with existing deficiencies or health conditions.
