🧠 Brain fog is real.

If you've ever struggled to remember names, lost your train of thought mid-sentence, walked into a room and forgotten why, or felt like your brain was moving through mudyou are not alone.

"Brain fog" isn't a diagnosis, but it is a recognised symptom of cognitive dysfunction and can occur with a wide range of conditions, including perimenopause, thyroid disorders, poor sleep, stress, viral illnesses and certain medications.

One of the biggest misconceptions I hear is, "Does this mean I'm getting Alzheimer's?" The answer is not necessarily. Occasional forgetfulness is common and has many possible causes. The important thing is to look at the whole picture and, if your symptoms are persistent, worsening or affecting your daily life, speak to your healthcare provider.

As someone navigating perimenopause and hypothyroidism myself, I know how frustrating brain fog can be. But you're not "lazy," "stupid," or "making it up." Your symptoms are real, and they're worth understanding.

💬 Have you experienced brain fog? What has it felt like for you? I'd love to hear your experience in the comments.

Here's something most people never think about. If someone develops numbness, tingling, difficulty walking, or unexplained anaemia, would you ever think to ask about their denture adhesive? Probably not. Some denture creams contain zinc, and when they're used in excessive amounts over a long period, that zinc can reduce copper absorption, leading to copper deficiency. It's uncommon, but it has happened. So if you or someone you know uses denture adhesive every day, it's worth checking whether it contains zinc and making sure it's used exactly as directed. Sometimes the missing clue isn't a rare disease... it's something hiding in plain sight.

Don't underestimate the power of breathing, at least it's something you can control and it's free 🤷🏼

2008 and you...
Thinking the degree was the destination.
Turns out it was just the beginning.
I'm still not sure it was the perfect career path, but I'm incredibly grateful for everything I've learned and how it's helped my family.

Can one enzyme really stop histamine symptoms?
DAO supplements are becoming increasingly popular for headaches, flushing, bloating and "histamine intolerance"... but what does the science actually say?
DAO (diamine oxidase) is an enzyme made in your small intestine that helps break down histamine from food before it's absorbed.
A small 2019 study found that people taking DAO before meals reported improvements in symptoms like bloating, diarrhoea, headaches and flushing.
Sounds promising... but here's the catch.
The study only included 28 participants, lasted 4 weeks, and didn't have a placebo group. So while the results are encouraging, they're not definitive.
It's also important to know what DAO doesn't do.
❌ It isn't an antihistamine. ❌ It doesn't stop your body from releasing histamine. ❌ It's not proven to treat allergies or mast cell activation syndrome (MCAS).
And despite what some people think, it's also unlikely to help the classic "Asian alcohol flush", which is usually caused by difficulty breaking down acetaldehyde, not histamine.
💡 My take?
If your symptoms consistently occur after eating histamine-rich foods, DAO may be worth discussing with your healthcare provider. But like any supplement, it's important to look beyond the marketing and understand what the evidence actually supports.
Have you tried a DAO supplement? I'd love to hear about your experience below.

Imagine iron is a parcel that needs to be delivered.
Copper is the courier.
Without the courier, the parcel never reaches its destination. The warehouse is full of parcels (iron stores), but the construction workers (your bone marrow) never receive them.
Taking more parcels doesn't solve the problem you need the courier to deliver them.

This doesn't mean everyone with anaemia needs copper supplements. Copper deficiency is relatively uncommon. However, if someone has anaemia that isn't responding as expected to iron, especially alongside low white blood cells or neurological symptoms, checking copper status may be appropriate.
