The Synergee Podcast
Lori Esarey and Kelly Engelmann talk with Catharine Arnston about how mitochondrial health connects to brain fog, fatigue and ageing. The conversation focuses on simple daily habits, plus the roles of spirulina and chlorella, in supporting cellular energy and long-term vitality.

The Energy Within: Mitochondria, Brain Fog and Ageing Without the Slowdown
Episode Overview
- Mitochondrial damage is described as a root driver of symptoms like brain fog, fatigue, weight gain and poor digestion.
- Catharine shares a simple health frame: focus on "nutrition in, toxins out" as the core ingredients for long-term vitality.
- Spirulina and chlorella are presented as highly nutrient-dense algae that may support mitochondrial function, detoxification and gut health.
- High carbohydrate intake and excess stress are linked to increased free radicals, lactic acid build-up and that stiff, achy feeling.
- Women may face added mitochondrial strain due to lower serotonin, declining oestrogen and reduced antioxidant protection with age.
“"I want people to know that aging is natural. Declining is not."”
What drives someone to seek a life that feels sharp, energised and clear at any age? This Synergee Podcast conversation leans hard into that question as hosts Lori Esarey and Kelly Engelmann sit down with returning guest Catharine Arnston, founder and CEO of ENERGYbits®, to chat about mitochondria, brain fog and ageing with more spark. Catharine has a knack for taking heavy biochemistry and turning it into kitchen-table chat.
She explains how mitochondria are the tiny "power centres" in your cells, why brain fog and fatigue often point to damaged mitochondria, and why, as she puts it, "aging is natural. Declining is not." You’ll hear her simple formula for health – "nutrition in, toxins out" – and how that plays out through daily choices like movement, clean food, sleep and stress management. The episode spends plenty of time on spirulina and chlorella algae, which Catharine calls “intelligent food”.
She breaks down how spirulina’s antioxidant superoxide dismutase and blue pigment phycocyanin may support mitochondrial function, and why chlorella’s chlorophyll, fibre and tryptophan content make it her go-to for gut health, detox support and even constipation. Her analogy keeps it memorable: spirulina as "room service" bringing nutrients in the morning, chlorella as "housekeeping" clearing toxins at night.
Lori and Kelly keep things grounded in real-life symptoms their audience brings to clinic: brain fog, stiffness, poor sleep, low energy and worries about cognitive decline. They repeatedly separate “mental energy” from “physical energy”, helping you think about tiredness in a new way. If you’re tired of feeling tired and curious whether your cellular energy has anything to do with it, this conversation might get you asking better questions about what you’re feeding your body – and your mitochondria.
What if feeling foggy isn’t “just getting older” after all?
