Bifidobacteria longum: Altruistic Keystone Flora of the Gut

Healthy humans and centenarians have a unique gut signature consisting of 1–5% Bifidobacteria longum. Studies show that by restoring and resurrecting this historically altruistic, brain-supportive, and immune-supportive species, health can be significantly improved.

• The altruistic role of this vital apex/keystone gut flora throughout evolutionary history over the last 100 million years (MYA) in bees, birds, and humans.
• The phylogenetic core microbiota shared by ancestral bees, ancestral and modern humans, and long-lived humans.
• The benefits of Bifidobacteria longum for healthy aging and overall vitality.

We will review clinical cases that highlight B. longum’s role in functional and regenerative medicine, as well as biohacking strategies to enhance health and longevity.
