Most floating stool is just gas.

True fat male absorption usually comes with other signs –– pale color, greasy texture, oily film, strong, smell, difficulty flushing.

One clue, rarely tells the whole story.

Digestion is about patterns.

Fibre changes stool.
It doesn’t retrain coordination.

When constipation involves straining, holding, or outlet dysfunction, this pattern often needs more than supplements.

When we measure serum magnesium, we’re checking whether your body has been able to keep magnesium stable in the blood.

Your body works hard to protect blood levels because things like heart rhythm and nerve signaling depend on them.

So if intake or absorption drops, the body will pull magnesium from tissues and cells to keep blood levels normal.

That means a “normal” serum magnesium doesn’t always mean your body has enough magnesium everywhere — it just means your body has kept blood levels safe.

This is why someone can have normal bloodwork and still have symptoms that improve with magnesium.

Over time in practice, noticing this pattern is what changed how I test. I now look at markers that reflect what’s happening inside cells, not just what’s being held steady in the blood — because that often explains symptoms that didn’t make sense otherwise.

Looking at magnesium inside red blood cells helps show whether your cells have had enough magnesium over time, not just whether blood levels are being maintained

Lab results don’t exist in isolation.
The same numbers can mean very different things depending on:
– the symptoms
– the physical exam
– the pattern of other markers
– the overall context of the system

A result that looks “normal” on paper can be limiting in one person
and completely appropriate in another.

That’s why interpretation matters more than any single test.

The goal isn’t to chase values —
it’s to understand what the body is doing with what it has.

When labs are read in context,
clarity usually follows.

I don’t control everything my kid eats.
I do control what’s in their lunch.
Homemade treats every week make lunches and snacks simpler.

If you saw my last post on frozen shoulder, this is the breakdown.

Sometimes frozen shoulders aren’t really a shoulder pathology per se.

When rehab, injections, and stretching don’t work, it’s often because we’re treating the wrong tissue.

Usually, by the time I see these cases, skilled clinicians have already addressed the local pathology with evidence-based care. That gives me the opportunity to look at the problem from a different angle.

It’s been shown that the liver has to accommodate diaphragmatic and thoracic movement during shoulder motion — which makes it a useful example of how visceral and organ-related fascial tension can influence musculoskeletal range and pain.

Glutathione is my go-to for clearing oxidative stress out of an overstimulated nervous system.
When your body’s running too hot — anxious, inflamed, or reactive — this molecule helps it cool down and recalibrate.

Most people I see in clinic have either a gut issue, a neurological issue — or both.
That’s why glutathione has become a staple here: the gut and brain are linked through oxidative stress.

When the gut lining gets leaky, oxidative stress spikes — and that same stress fuels neuroinflammation.
It’s a two-way street: gut barrier damage drives brain inflammation, and brain inflammation worsens gut function.
Glutathione sits right in the middle — defending both.

Of all the neurological issues I use it for, it’s most often a “chill pill” for people with a wired, anxious, or overactive nervous system.
That kind of nervous system overactivity is everywhere today — and glutathione helps calm it, fast.

With the right form, you can actually feel it within minutes.
And since our own production drops with age, keeping levels up supports longevity, resilience, and recovery. 🧬
