Why Energy Starts in the Cells – and What Mitochondria Have to Do with Real Regeneration
Michaela Altenberger,
Three questions that make all the difference:
• Why do people feel chronically fatigued even after getting enough sleep?
• What’s really happening in the body when cellular energy production stalls?
• How can the power plants of our cells be specifically reactivated?
It’s 3 PM. You slept well, but you still feel like an Phone with 3% battery left. The coffee helps—for a moment—then comes the crash. What we often label as “tiredness” is in many cases a desperate cry for help from energy-depleted cells.
Energy is created inside tiny power plants that operate within each of the body’s 37 trillion cells: the mitochondria. When these bean-shaped organelles start to falter, the effects are felt throughout the system—manifesting as heaviness in the limbs, mental sluggishness, or the struggle to make even simple decisions.

The Architecture of Life
Each cell is like a highly complex factory. Mitochondria are its generators—but not just any kind. After food is digested and glucose enters the bloodstream, it reaches the cells, where it is converted through oxidation into ATP – adenosine triphosphate – the universal currency of all life. Without ATP, nothing works: no heartbeat, no thought, no movement. Even during sleep, every cell consumes energy. The brain alone—just two percent of body weight—uses up 20 percent of total energy. Neurons, in particular, demand a constant and optimal energy supply. But these internal generators are fragile. Stress, toxins, chronic inflammation, and nutrient deficiencies can all impair their function. Over time, they produce less ATP and more oxidative waste. Aging doesn't begin with time—it begins when cells lose their energetic vitality.
When the Internal Engines Stall
The consequences are tangible: a fatigue that no amount of sleep can fix. A weakened immune system that turns every cold into a battle. Brain fog that makes simple tasks feel overwhelming. Diminished physical and mental resilience, often dismissed as “just getting older.”What many don’t realize is that the brain, with its high energy demands, suffers the most when mitochondrial function declines. Optimal mitochondria performance is key to mental clarity and focus. And so, the cells begin to starve for energy—ironically, in a world of abundance. At the Krallerhof, this connection is not only recognized but actively addressed through tailored therapies. True regeneration begins where life truly happens: inside the cell.
