The mechanism

Being this tired shouldn’t be the new normal

Being low-energy all the time isn’t just stress, sleep, or age. It’s often a sign of cellular decline — the body loses NAD+ and B12 over time, both of which power focus, movement, and mood.

With evidence-backed treatments that improve cellular energy and balance the immune system, fatigue can stop feeling like something you have to push through.

01

NAD+ & mitochondrial output

NAD+ is a central regulator of cellular energy metabolism. Levels decline with age, and restoring them supports mitochondrial function.

02

B12 & nerve signalling

Even within normal ranges, lower B12 is associated with slower processing speed and impaired neurological function in older adults.

03

Inflammation & immune balance

Low-grade inflammation quietly drains energy. Immune-modulating protocols can support quality of life alongside cellular nutrients.

FAQ

Frequently asked questions

What is the best treatment for low energy?

It depends on the underlying cause. NAD+ Injections may help support cellular energy metabolism and mitochondrial function; B12 Injections may help support energy levels in those with low or suboptimal B12; Low Dose Naltrexone may help support immune balance and overall energy; Sermorelin may help support natural growth-hormone signalling, playing a role in energy, recovery, and body composition. A licensed provider will review your history to help determine which — or which combination — fits.

Why am I always tired even when I sleep enough?

Persistent fatigue despite adequate sleep is often a sign of cellular decline rather than lifestyle habits alone. As the body ages, levels of key cellular nutrients like NAD+ and B12 naturally decrease, affecting how efficiently cells produce energy.

Can I use more than one treatment at the same time?

Every person’s biology is different, which is why we take a personalised approach rather than a one-size-fits-all protocol. After you complete your online intake, a licensed provider will review your health history, symptoms, and goals to determine whether a single treatment or a combination is appropriate. Your care team continues to monitor and adjust over time.

How long does it take to feel more energy with these treatments?

Timelines vary. Some people notice initial changes in the first few weeks, while more consistent improvements often emerge between 30 and 90 days. Individual experiences depend on age, baseline health, lifestyle habits, and adherence. Your provider will monitor progress and may adjust your protocol.
