Supplements

What may help fill real gaps, and what is mostly hype.

Arnold SchwarzeneggerAge 78
9/10Science Score

Arnold Schwarzenegger said“Eat enough protein and keep lifting, and you hold on to your muscle as you age.”

The science saysStrongly supported. Protein plus resistance training is one of the best-proven ways to protect aging muscle.

Why this scoreBacked by multiple clinical trials.

Verdict: Real, and worth copying.

Jennifer AnistonAge 57
6/10Science Score

Jennifer Aniston said“A daily scoop of collagen peptides keeps your skin, hair, and joints younger.”

The science saysPartly true. Trials show collagen can help skin, but the strongest results come from industry-funded studies, and the hair and joint case is thin.

Why this scoreTrials exist, but sellers funded them.

Verdict: It works on skin. It also works for the company she runs.

Halle BerryAge 59
6/10Science Score

Halle Berry said“The ketogenic diet reversed my health problems and slows down my aging.”

The science saysHalf right. Keto can lower blood sugar in the short term, but 'reversed it' is a louder claim than the trials will sign off on.

Why this scoreTrials show short-term help only.

Verdict: Keto earns a B. 'Reversed it' is grading on a curve.

Gwyneth PaltrowAge 53
7/10Science Score

Gwyneth Paltrow said“A long daily intermittent fast, coffee then bone broth, keeps me well and detoxed.”

The science saysOverstated. Intermittent fasting works about as well as simply eating less, with no special detox or longevity magic.

Why this scoreTrials show it works like any diet.

Verdict: Skipping breakfast is a tool, not a detox spell.

David SinclairAge 56
3/10Science Score

David Sinclair said“Taking resveratrol every day helps slow down human aging.”

The science saysNot established in people. Resveratrol extended life in mice on a rich diet, but human trials and a failed drug program never showed the benefit.

Why this scoreProven in mice, not in people.

Verdict: Spectacular in a mouse, unproven in a professor.

Bryan JohnsonAge 48
3/10Science Score

Bryan Johnson said“A strict protocol of food, sleep, exercise, and more than one hundred daily supplements can measurably slow how fast you age.”

The science saysNot established. The basics help, but slowing human aging with a large supplement stack is unproven, and a routine of one person cannot prove it works for anyone else.

Why this scoreToo early, and tested on one person.

Verdict: Measure all you want. The anti-aging headline is running ahead of the evidence.
