Best Supplements for Longevity

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 supplementation. Huberman, Attia, and Patrick are the strongest advocates, each featuring dedicated deep dives on creatine's benefits for both physical performance and cognitive function. Johnson includes creatine in his Blueprint longevity stack. Hyman recommends it as one of his six essential daily supplements for muscle mass, insulin sensitivity, and brain health.

All 5 experts agree that gut microbiome health is foundational to longevity, immunity, and brain function. The strongest consensus is around fermented foods over probiotic supplements. Huberman recommends 4 servings of low-sugar fermented foods daily as the primary intervention. Attia takes a science-forward approach, personally using Pendulum Akkermansia and AG1 while emphasizing that the probiotic market is largely unregulated. Patrick highlights the Sonnenburg research showing fermented foods increase microbial diversity and reduce inflammatory markers. Hyman is the most prolific advocate, outlining a comprehensive 5R gut-healing protocol and recommending probiotics as one of his foundational supplements. Johnson includes fermented foods in his daily Blueprint meals.

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.
