Most people think cholesterol is the most important marker on a blood test.

Sometimes it isn’t.

Before I even get to cholesterol, I often find myself reviewing:

🩸 HbA1c - provides a longer-term overview of blood sugar regulation over the previous 8–12 weeks and can offer insight into metabolic health and future risk.

⚡ Ferritin - iron storage and oxygen delivery.

🧠 Vitamin B12 - (I ideally prefer Active B12 and MMA, with Homocysteine where appropriate) - neurological function and energy production.

☀️ Vitamin D - immune, hormonal and musculoskeletal health.

🦋 TSH - thyroid signalling and metabolic health.

These markers can often provide valuable clues regarding energy, metabolism, blood sugar balance, thyroid function, methylation concerns, cardiovascular risks, nutritional status and overall health.

Of course, no blood marker should ever be viewed completely in isolation.

The real value comes from understanding the patterns and relationships between biomarkers rather than focusing on a single result.

This is often where the biggest clues are hiding.

Which blood marker has surprised you the most after testing?

Thank you to everyone who has recently enquired about our London VIP Health Screen, and those that have benefited from it🩸

The test includes 55 biomarkers, but rather than focusing on all 55 at once, I thought I’d highlight a few of the markers I often review first when assessing a patient’s health picture.

✔ Ferritin
✔ Vitamin B12
✔ HbA1c
✔ TSH & Free T4
✔ ESR

Of course, no biomarker should ever be viewed completely in isolation, but these markers can often provide valuable clues regarding energy, metabolism, blood sugar regulation, thyroid health and inflammation.

This is where interpretation becomes important. Sometimes the biggest clues are not the results that are flagged red, but the patterns that emerge when biomarkers are viewed together.

Stuck at Type 1–2 stools? It’s not always just “low fibre.”

If your bowel movements are hard, dry or infrequent, there are usually deeper drivers involved.

Most people are told:

“Just eat more fibre.”

But clinically, that’s often too simplistic - and in some cases, it can make things worse.

Here’s what we actually assess:

* Hydration status > fibre without adequate fluid can lead to harder stools
* Gut motility > slow transit allows excessive water reabsorption in the colon
* Magnesium levels > essential for bowel movement and smooth muscle contraction
* Type of fibre > not all fibres behave the same (soluble vs insoluble matters)
* Microbiome balance > gut bacteria influence stool consistency and function

This is where targeted fibres may be introduced.

For example, PHGG (Partially Hydrolysed Guar Gum) may be used clinically due to its:

* Gentle tolerance profile
* Lower likelihood of bloating compared to other fibres
* Prebiotic support for beneficial bacteria
* Ability to support more consistent stool formation

But here’s the key:

It’s not about adding more.
It’s about adding the right thing, in the right context.

Selection always depends on the individual case, symptoms and tolerance.

Here’s a Bristol Stool Chart – a simple yet clinically recognised tool used across medicine to assess bowel health.

If you’re experiencing bloating, constipation, urgency, irregularity or gut discomfort, your stool type gives valuable insight into what’s happening internally - especially within a functional medicine model, where patterns matter.

Quick breakdown:

* Type 1–2 (Hard, lumpy)
* Indicates constipation
* Often linked to low fibre + dehydration
* Consider increasing soluble fibre + fluid intake
* Type 3–4 (Formed, smooth)
* Optimal stool
* Reflects balanced fibre intake, hydration, and gut motility
* Type 5 (Soft, easy to pass)
* Borderline low fibre
* May need more structured fibre intake
* Type 6–7 (Loose to liquid)
* Indicates inflammation, stress, infection or food intolerance
* Prioritise hydration + investigate triggers
* Seek support if persistent

Your stool is one of the most underused clinical indicators of digestive and metabolic health.

If it’s not Type 3–4 consistently, it’s worth exploring further.

Exploring NMN for cellular energy and mitochondrial support.

I’m now two weeks into trialling NMN (sublingual powder), taking 500 mg first thing in the morning on an empty stomach. Alongside this, I’ve continued a core protocol including active vitamin D (calcifediol), magnesium bisglycinate, and a methylated B complex, as well as agnus castus for hormonal support.

What I’ve observed so far is not a stimulant-type “boost”, but a more subtle, sustained sense of energy - particularly in how the body maintains function under fatigue and stress. That distinction is key.

NMN supports NAD⁺ production, which plays a central role in mitochondrial function, cellular repair, and energy metabolism. So rather than masking fatigue, the aim is to support energy at a cellular level.

Early impressions - supportive for overall energy resilience within a broader protocol. I’ll continue to assess as the trial progresses.

A special thank you to Alex, founder of for reaching out and sending over their UK’s first all-in-one collagen super-blend for me to trial.

Inside the box:
– High-speed milk frother
– Collagen super-blend (vanilla, 182g)
– 3 sachets (chocolate + vanilla)
– Storage tin
– Magnetic reminder calendar

This formulation combines:
– Grass-fed + marine collagen
– Liposomal Vitamin C
– Hyaluronic acid
– Biotin (5,000 mcg)
– Zinc, Vitamin D, Vitamin K, B12 (methylcobalamin)

Designed to support:
– Skin, hair & nails
– Joint health
– Immune function
– Structural integrity of connective tissue

Why collagen?
Collagen is one of the most abundant structural proteins in the body and plays a key role in maintaining skin integrity, connective tissue strength, joint health, and repair processes.

As we age - and particularly under stress, inflammation, or hormonal imbalance - collagen production can decline. Supporting these pathways alongside nutrition and lifestyle can help maintain overall function and resilience.

I’ll be trialling this and sharing my honest practitioner feedback in due course.

A busy morning in clinic…

Powered by NMN powder by , morning consultations, and taking a moment to reset in between.

Currently trying the NMN powder by - an interesting one to explore.

Also… I know the sleep mist is technically for night-time, but I love it that much I’ve been spritzing it in the office too - creates such a calm space between consultations.

Powered by NMN, a pause, and a hot cross bun from ☕️

A well-supported practitioner supports others better. 👩🏻‍⚕️
