Old Friend.
New Resilience.

A different pathway.
A measurable difference.

Stress tools often work through one pathway: the hormonal. Cold plunge, breathwork, cortisol, the HPA loop — it's all the same, over and over.

But there is another lever. Stress is not only hormonal. It's also immunological.

Your body's inflammation is a volume knob on stress — the higher it's turned, the harder everything hits.

And modern life has turned it up… way up.

It also handed you the most sterile environment in human history. As a result, your immune system has never met the organisms humanity has spent millions of years evolving with. The very things that can turn down that knob.

Science has a name for these: Old Friends.

KGA-10™ is one of them — hand-picked, high-performing. In the 2026 randomized, placebo-controlled clinical trial, 94% of healthy adults reported reduced perceived-stress scores within two weeks, and hs-CRP fell 25% versus placebo.
