Best Supplements for Men Over 40

All 5 experts actively recommend omega-3 supplementation, making this one of the strongest consensus topics. Patrick and Attia provide the deepest mechanistic coverage, Huberman recommends 1-3g EPA for mood and cognition, Hyman lists omega-3 as a foundational supplement everyone needs, and Johnson includes omega-3 sources in his Blueprint diet.

All 5 experts actively recommend creatine — and the consensus has expanded well beyond muscle. Huberman, Attia, and Patrick each feature dedicated deep dives on creatine as brain fuel for cognition under stress, sleep deprivation, and aging — not just strength and hypertrophy. Johnson includes it in his Blueprint stack; Hyman names it one of six essential daily supplements for muscle mass, insulin sensitivity, and brain health as we age. The most common worry — elevated creatinine on bloodwork — is a harmless artifact of muscle metabolism, not kidney damage.

4 of 5 experts actively recommend magnesium supplementation. Patrick and Hyman are the strongest advocates, each discussing it across multiple videos. Attia recommends 300-500mg daily for bone health and personally supplements with three forms. Johnson's Blueprint stack does not explicitly include magnesium.

4 of 5 experts recommend vitamin D supplementation for those with suboptimal levels, though Attia urges caution — arguing that the health benefits attributed to high vitamin D may actually come from the outdoor lifestyle needed to achieve them naturally. Patrick is the strongest advocate, citing a 40% reduction in dementia risk.

4 of 5 experts actively recommend more protein than the 0.8 g/kg RDA — converging on roughly 1.2-2 g/kg paired with resistance training (Johnson's coverage is thinner and plant-forward). The 'high protein shortens lifespan' fear traces mainly to guest Valter Longo's low-IGF-1 view; the core experts largely resolve it by noting that exercise redirects IGF-1 toward muscle and that sarcopenia — not mTOR — dominates aging risk after 50.
