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. 🧬

Do you judge an exhausted person equally to a “lazy” person?
🥱🥱🥱🥱🥱🥱🥱🥱🥱🥱🥱🥱 What if you’re not lazy… you’re just tired?
I see it all the time — people dragging themselves through the day, feeling guilty because they “should” have more energy.
But here’s the tea ☕: fatigue isn’t a personality trait. It’s a symptom. And symptoms have causes.
Iron deficiency. Thyroid issues. Blood sugar dysregulation. Poor sleep quality. Chronic infections. Low stomach acid. Adrenal strain.
Before you label yourself (or someone else) as “lazy,” ask: 🔍 Has there been a full workup? 🔍 Are you nourishing and absorbing what you eat? 🔍 Is your body trying to tell you something?
You can’t shame someone into having energy. But you can figure out what’s draining it.
🚫 Lazy. ✅ Undiagnosed.

Most probiotic prescriptions?
Still just a kick-and-hope move.
But if you’re walking around with:
* 🧈 Floating, pale, or sticky stools
* 🥴 Nausea or fullness after eating fat
* 💨 Bloating up high (not just in your pants)
* 💩 Stools that smear or show food bits
* 🔁 Gut issues post-antibiotics..you’re not looking at a colon issue. You’re looking at foregut dysfunction — stomach acid, bile, and enzymes not showing up to work.
👉 If you’re not supporting the foregut, you’re just cleaning up messes further down.
🎯 What to do about it:
🟢 L. reuteri DSM 17938
* Supports bile & gut movement
* Calms inflammation, especially post-antibiotics or in kids
* Great first step for gentle rebalancing
🔵 HU58 (Bacillus subtilis)
* Stimulates enzymes + bile
* Rebuilds upper gut terrain
* Stronger — start slow, respect the heat
Match the probiotic to the physiology. Start where digestion starts. No more kick-and-hope.

Most patients don’t need more healthy tips—they’re already overwhelmed with advice. What they really need is ENERGY to follow through. A cell can’t thrive in low-energy conditions—without ATP from mitochondria, processes like repair stall!
Have you had your checked? WITH
- Inflammation markers AND
- and serum iron …..

IF sickness leads to fatigue due to metabolic demand and fatigue and low energy states lead to compromised cellular metabolism…
THEN …
Does sickness precede fatigue or vice versa?

I have seen a great many patients with conditions who also have a stomach condition, as per my clinical evaluation (which includes symptoms, informed physical examination, and workup).
If you've got a thyroid condition and a stomach condition such as H. pylori, you'll likely have to take care of the to address the thyroid.
Practical note for Ontario residents: NDs in Ontario can order H. pylori breath and stool tests.

While studying homeopathy in great depth as a naturopathic medical student I was able cure my mother’s fibromyalgia symptoms and my own colitis.
How I became a naturopathic doctor is much less dramatic; more a consequence of my abilities in the sciences combined with curiosity, the privilege of being raised in a middle class Canadian household, and the need to express important values and principles in my work, such as integrity, compassion, and meaning.
During my Honours Science degree at the University of Waterloo (where I achieved Dean’s Honour with Excellent Standing) I considered a career in pharmacy, then made an unsuccessful attempt to get into medical school. I was disillusioned and didn’t have much of a focus, so soon after I found myself living on a beach in New Zealand asking a lot of existential questions that I was privileged enough to have the opportunity to contemplate.
It was during my time there that I first recall hearing about homeopathy from a close friend; after conventional medicines and antibiotics had failed him, he was cured of his collapsed lung and pneumonia by a homeopath.
His compelling story led me to research more into the area of natural and traditional forms of health care, and it was then that I first encountered the word (and profession) ‘naturopathy’. A pluralistic approach, naturopathic medicine takes the best of various forms of traditional medicine and complements them with a scientific, research-based approach.
In a time of polypharmacy and widespread dissatisfaction with the conventional medical system, it is an ideal solution.
Naturopathic medicine makes so much sense and it is rooted in altruistic philosophical principles which are vital not only to the profession, but also to my need for meaning and alignment of heart and mind with my work.
Naturopathic medicine is many things.
It is scientific and logical.
It is safe and effective.
It stimulates personal growth and healing.
It works in alignment with incontrovertible Laws of Nature.
It is rooted in sound philosophical tenets.
It helps fill in the gaps in the present conventional health care system.
I am proud to be a practitioner of the naturopathic medical art. I am honoured and privileged to be able to help people grow, heal, become well, lessen pain, and together become better versions of ourselves.
