Recent peer-reviewed research on the Younger You program reveals that: The Younger You program can increase your intake of beneficial, phytonutrient-dense foods more than other diet programs studied for their beneficial effects on bio age (like the Mediterranean diet).
There’s a red flag I’ve learned to pay close attention to in clinical practice—and it’s not just elevated homocysteine or a sluggish DUTCH test. It’s when a new patient mentions they live on or near a golf course.
Prompted by the increase in exposure to wildfire smoke, researchers at the University of New Mexico put together this graphical representation of how environmental toxins are known to affect the hallmarks of aging.
Berberine is a common choice in the functional medicine community to aid patients in blood glucose regulation. Up until March 2025, there were 30 randomized controlled trials on PubMed investigating this connection. Now, a new study published in a prestigious Journal of the American Medical Association publication (JAMA Network Open) brings that number to 31.
