The Circle by Nina Kalandia

Your body isn’t broken. It’s out of rhythm and out of resources.

In this community, we look at the human body as an intelligent, self-regulating system with intricate timing and hardware: circadian and seasonal rhythms on one side, mitochondria, metabolism, and the nervous system on the other.

I’m a filmmaker turned metabolic health nerd who rebuilt my own energy by fixing foundations instead of chasing random hacks and protocols.

I attend the summits, dive into the research, and test the tools so you don't have to. You get clear summaries, practical takeaways, and simple rituals that support mood, sleep, metabolism, and healthy aging, without needing to live in conference portals.

Perfect for humans who feel civilized out of sync with their own biology and want back in.

Inside you’ll find monthly Q&As, weekly discussions, distilled summit + research notes, and support applying foundations like light, sleep, mitochondria, movement, minerals, and seasonal living to real life.
