You don’t suddenly lose energy.
You notice it in patterns.
You recover slower
Your energy drops earlier in the day
Focus takes more effort
This is not just fatigue.
It’s your cellular energy system becoming less efficient.
Most solutions try to push energy.

By combining Ca-AKG with Carnitine, CoQ10 and B12, you support:
how fuel enters your cells
how energy is generated
how consistent that energy feels
The result:
Energy that holds up — physically and mentally.

Not by stimulation — but by improving how energy is produced
Your energy is created inside mitochondria.
And that process depends on multiple steps working together.
L-Carnitine transports fatty acids into the mitochondria
Ca-AKG supports the Krebs cycle (core energy metabolism)
CoQ10 supports ATP production (usable energy)
Vitamin B12 contributes to normal energy metabolism¹
If one step slows down, the whole system becomes less efficient.
This formula supports the flow between those steps.
Approved health claims:
¹ Vitamin B12 contributes to normal energy-yielding metabolism and reduction of tiredness and fatigue, Vitamin B12 contributes to the reduction of tiredness and fatigue
² Calcium contributes to normal muscle function, Calcium contributes to normal energy-yielding metabolism

These ingredients are studied individually — but their combined effect lies in how they support the same energy system.
Energy production is not one mechanism.
It’s a chain.
Ca-AKG supports the core metabolic cycle
Carnitine supports fuel delivery
CoQ10 supports energy conversion
B12 supports overall metabolism
Most products either isolate one ingredient or overload the formula.
This approach is different:
just what’s needed — nothing extra
A clear, structured formula designed for long-term use.

Prof. Dr. Andrea Maier is an internist and professor of aging (“ longevity medicine ”) at the Vrije Universiteit in Amsterdam and the University of Melbourne, Australia. She studies the aging body and searches for anti-aging treatments. She heads the Center for Healthy Longevity in Singapore.
Why do we gradually decline during our average life of more than 80 years? Can we stop that process? Or maybe even turn around? And to what extent should we really want that? Maier gives practical tips on how we can extend our lifespan while also staying healthy.
Andrea Maier graduated in Medicine from the University of Lübeck in 2003. She specialized in internal medicine at the Leiden University Medical Center and subsequently chose the subspecialty of Geriatric Medicine. This is where she started her research into aging.
