How much protein do I need after 60?

Evidence-based answer

Probably a little more than when you were younger. More protein goes with more muscle in older adults,1,2 especially alongside strength training.3

@AllNutrition do I need more vitamin B12 as I get older?

AllNutrition

Absorbing B12 from food tends to get harder with age, so low levels are more common in older adults,1,2 and fortified foods or a supplement can close the gap.3

Asked again later

Does creatine help older adults keep their strength?

Taken alongside strength training, it is linked with modest strength gains in small trials,1,2 and a newer pooled analysis of trials points the same way.3

The library keeps growing as new research is published, so the same question can return a fuller answer.

Good questions

What people ask before their first question.

Where do AllNutrition's answers come from?

Every answer is built from a curated library of over half a million peer-reviewed papers, growing every day, plus the most reputable clinical guidelines from organizations like the WHO, CDC and American Academy of Pediatrics. Every paper gets a trust score, conflicts of interest are flagged, and every answer cites the exact sources it used.

How up to date is the research?

New research is added to the library every day, so answers improve over time. Ask the same question a month from now and the answer reflects the newest evidence, not a stale snapshot.

How do you grade a paper?

Each paper is rated on four things: how well the study was designed and run, its independence from funders with a stake in the result, how openly it was reported, and how strongly its evidence supports its claims. The trust score is the average of those ratings. Low-scoring papers rank lower instead of disappearing, conflicts of interest carry a badge, and the full rubric is public.

What is an evidence panorama?

A panorama is a big-picture report: it reads every relevant paper in the library on your question, weighs each one by trust, and shows where the evidence points, from longevity habits to everyday risks, with every claim traceable to its sources. Because the library keeps growing, running a panorama again later shows how the picture changes.

Is AllNutrition free?

Yes. Asking questions, exploring the evidence behind every answer, and the Research Digest are all free.

Is this medical advice?

No. AllNutrition summarizes what published research and clinical guidelines say, with citations so you can check everything yourself. For decisions about your health, talk with your clinician, and bring the sources with you.
