Cognitive decline does not always present as overt neurological disease. Subtle changes in focus, memory, mental stamina, and information processing are increasingly common particularly among high-performing professionals, post-viral patients, and individuals under chronic stress.
These symptoms are often attributed to lifestyle factors or age, but emerging evidence points to structural and biochemical disruptions at the cellular level of the brain.
For individuals who experience cognitive dysfunction without formal diagnoses, conventional treatments may offer limited benefit.
Cerebrolysin is a neuropeptide-based therapy with clinical application in neurological repair, increasingly used to support cognitive function in functional and precision medicine settings.
Mechanism of Action
Cerebrolysin is composed of low molecular weight peptides (under 10,000 Daltons), which enables it to cross the blood–brain barrier and act directly within the central nervous system.
Once administered, it interacts with the neurovascular unit, a complex interface of neurons, glial cells, endothelial cells, and microcirculation, to support neuroplasticity and repair.
It has been shown to:
- Modulate neuroinflammation
- Promote synaptic communication
- Protect neurons from oxidative stress
- Stimulate neurotrophic activity
- Improve cerebral microcirculation
Cerebrolysin is also formulated with essential minerals including magnesium, potassium, phosphorus, and selenium, all of which play roles in neuronal signalling and mitochondrial energy production.
Clinical Context and Regulatory Use
Cerebrolysin is an approved therapeutic agent in over 44 countries, particularly in Europe and Asia, where it is widely used for post-stroke recovery, traumatic brain injury, and age-related cognitive decline.
In functional medicine contexts, it is now being explored for use in individuals presenting with brain fog, mental fatigue, or executive dysfunction related to chronic stress, neuroinflammation, or long COVID.
It is not a stimulant or a nootropic in the conventional sense. Rather, Cerebrolysin supports neurorestoration at the cellular level and is often used within broader protocols aimed at cognitive optimisation.
Therapeutic Indications
While each case is evaluated individually, Cerebrolysin may be considered in clinical peptide protocols for individuals presenting with:
- Cognitive dysfunction not explained by formal diagnoses
- Long COVID-associated cognitive symptoms
- Post-inflammatory or stress-related neurological fatigue
- Executive performance decline in mid-life professionals
- Neurological ageing prevention in high-functioning individuals
Its mechanism positions it as a neurorestorative therapy, not a performance enhancer, with emphasis on underlying repair, not acute stimulation.
In the broader picture of brain health, peptide therapy has become one of the most precise tools we have for restoring function at the cellular level, where symptoms actually begin.
When tailored properly, it doesn’t just manage decline, it helps reverse it.

Clinically Supported Administration Pathways
At Nūūtro, Cerebrolysin is prescribed within a structured protocol based on individual needs, history, and clinical goals.
It is available in two primary formats:
- Intravenous Infusions (5–50ml): Administered at our Mayfair clinic under medical supervision. This format is ideal for patients seeking intensive or higher-volume delivery. Home infusion options are available upon request.
- Subcutaneous Injections (At-Home): A flexible option for those preferring self-administration. Dosing protocols are customised, and full clinical support is provided throughout the treatment period.
We use authentic and original Cerebroylusin from Austria ensuring clinical-grade quality in every protocol.
Protocol Structure and Ongoing Support
Initial Consultation and Plan Design
It starts with a 1:1 clinical consultation This includes a detailed assessment of cognitive symptoms, lifestyle variables, and optional biomarker analysis to inform protocol structure.
Month 1: Prepped, Delivered, Ready
Your Cerebrolysin protocol is delivered through your chosen Cerebrolysin format along with administration guidance.The protocol is tailored based on response expectations, medical history, and clinical objectives.
Months 2–3: Monitoring and Adjustment
Progress is assessed through structured follow-up, symptom tracking, and dose modulation as needed. You have unlimited access to the Nūūtro clinical team for ongoing support and protocol refinement.
Protocols begin at £400/month, including your consultation, personalised peptide protocol, and 1:1 guidance throughout.
Our peptides are sourced from FDA-approved laboratories and EU GMP-approved facilities with the highest quality assurance on the market.
Evidence-Led Outcomes
Cerebrolysin has been used internationally in neurology for over two decades. Clinical use has shown improvements in cognitive clarity, focus, and mood regulation in both post-acute and functional populations.
