Foundational Four: Core

Personalisation is a journey, not a race. It is a step-by-step process of lifestyle changes that compound over time. But even before you dive deep into your genetic data, it is vital to lay a solid foundation.

1. Vitamin D: The immunity architect
Vitamin D is vital for immunity, bone strength and metabolism. Deficiencies are often tied to aging issues like heart disease and cognitive decline. By protecting DNA integrity, it plays a key role in slowing the biological aging process.
The personal take: Most individuals need supplementation, especially in low-sunlight environments, but absorption rates vary based on genetics. Aim for optimal blood levels between 40–60 ng/mL.

2. Fish oils (EPA/DHA): The anti-aging shield
Omega-3 fatty acids are the ultimate multitaskers, providing anti-inflammatory, neuroprotective and cardioprotective benefits. They help keep cell membranes fluid and may even slow telomere shortening (a marker of aging).
The personal take: Look for high-quality, purified triglyceride forms to ensure you are protecting your heart and brain without the risk of oxidation or contaminants.

3. Magnesium: The master mineral
Involved in over 300 enzymatic reactions, magnesium is non-negotiable for mitochondrial health, deep sleep and stress resilience. It is vital for regulating insulin sensitivity and aiding muscle recovery.
The personal take: Deficiency is incredibly common. For brain and nervous system benefits, magnesium glycinate or threonate is recommended over other forms that are harder to absorb.

4. Multivitamin with methylated B-vitamins
B-vitamins drive methylation, DNA repair and energy metabolism. However, not all B-vitamins are created equal.
The personal take: This is where genetics play a huge role. If you have the MTHFR gene variant, your body struggles to process standard B vitamins. Even in the absence of genetic testing, utilising a multivitamin with methylated B vitamins offers significant benefits. A quality multivitamin with methylated B6, folate (B9), and B12 ensures your body can actually use these nutrients for detoxification and cognitive protection.
