Live Longer. Feel Stronger. Age Smarter.
About DrAIFIT
DrAIFIT was started by Bert Cale out of a simple frustration: health advice for adults over 50 is either dumbed down into clickbait or buried in medical jargon nobody has time to decode.
Bert is a dedicated researcher and translator of science — not a clinician. His work is taking peer-reviewed research and guidance from sources like the National Institute on Aging, NIH, CDC, and FDA, and turning it into practical, plain-English advice on heart health, brain function, immune support, and everyday energy — with special attention to living stronger and more independent after 60.

How we work
Every article is evidence-informed and stamped with a "last reviewed" date. When we evaluate products, we do it as an independent publisher — we explain what the science actually says, what to watch out for, and where to find official product information. We are not owned or operated by any brand we cover.
