Chronic fatigue and B vitamins: do you need them?

B vitamins are essential for energy production—but that doesn't mean supplements will automatically fix your fatigue.

The truth: if you're deficient, supplementing helps. If you're not, it won't do much.

The problem? A lot of people with chronic fatigue ARE deficient—especially in B12, folate, and B6.

Why Luteal Phase Hits Hard (PMDD + ADHD)
If you’re a woman with ADHD and your luteal phase feels like life on hard mode, you’re not imagining it.
PMDD is a hormone-sensitive mood disorder and is best understood as sensitivity to normal hormone changes (not “bad hormones”). When you add ADHD, the luteal phase can amplify executive dysfunction, emotional regulation load, sleep vulnerability, cravings, and gut symptoms.
Fibre isn’t a cure — but it can be a practical lever for symptom load by supporting:
bowel regularity (luteal progesterone can slow gut motility)
blood sugar stability (fewer spikes/crashes can reduce irritability + cravings)
gut–brain signalling (emerging evidence)
If you have IBS, this is not a “more fibre at all costs” message — it’s slow, tolerable, personalised.
More on introducing fibre gently (without wrecking your gut) on my blog: https://www.persistentnutrition.com/blog

If You Fall Apart When You Can’t Exercise…

If you’re a woman who’s relied on exercise to “keep it together”… and then injury, chronic illness, burnout, perimenopause, or parenting reduced your capacity to exercise — and your focus, mood, and functioning noticeably worsened — that can be a useful ADHD clue.

Many women with undiagnosed ADHD use exercise as an unintentional regulation strategy. Not because they’re “more disciplined”, but because exercise can temporarily support neurotransmitters involved in attention and self-regulation (dopamine and noradrenaline).

For some people, that means:
improved focus and task initiation
reduced internal restlessness
improved emotional regulation and stress tolerance
The catch is: if exercise is your main regulation tool, it can also become part of the “mask”. You may appear to be coping well — until illness, injury, or hormonal shifts take that support away.
This isn’t a diagnosis. But if this feels familiar, it may be worth exploring ADHD — especially because women are often missed when they’re high-masking.
I’m posting the longer personal version on YouTube on Wednesday.

If you want Part 2 on low-energy, chronic-illness-friendly movement that still supports an ADHD brain, comment PART 2 or ADHD.

Chronic illness? Forget food rules and guilt.

Ever feel like every nutrition tip is made for someone with zero pain, zero meds, and infinite energy? Yeah, me too. That’s why my approach is: no food dictators, no shame, just practical support for real bodies dealing with real stuff.

Here’s the thing. You can eat to support your body—even when symptoms are loud, energy is low, and your fridge is giving 'mystery box challenge' vibes. No perfection required. No scales or measuring tape, ever.

Curious what that actually looks like in your life? Let’s chat. Book a free discovery call and bring all your questions. Your body, your pace, your rules. 💜

Gut health myths the internet won't stop repeating

Detoxes. Cleanses. Expensive probiotics. Restrictive elimination diets.

The wellness industry loves a good gut health trend—but most of it is expensive nonsense with zero evidence.

Swipe through for what actually supports gut health (and what's just marketing).

**When Fermented Foods Make You Feel Worse (Histamine)**

If fermented foods make you feel worse, you’re not “doing gut health wrong”.
You might be dealing with **histamine**.

Some classic gut-health staples can be **high histamine** (or trigger histamine release), like:
- Fermented foods (kombucha, sauerkraut, kefir, yoghurt)
- Aged/processed foods
- Leftovers (histamine builds over time)
- Certain fish/seafood (especially if not super fresh)

If histamine is part of your picture, the “eat more fermented foods” advice can be the exception — not the rule.

This isn’t a “never eat these foods” post. It’s a “let’s reduce the load and get strategic” post.

Want a Part 2 with **low-histamine gut support swaps**? Comment **HISTAMINE**.

Magnesium for fibromyalgia: what the research actually says

Magnesium gets hyped a lot—but for fibromyalgia, there's actually solid evidence behind it.

Research shows magnesium can reduce muscle pain, improve sleep quality, support nervous system regulation, and reduce fatigue.

The catch? Not all magnesium is created equal. And food sources matter just as much as supplements.

Histamine Intolerance + Christmas: Easy Tips to Survive the Festive Season

If you suspect histamine intolerance, the festive season can feel like a minefield: leftovers, cheese boards, wine, stress, late nights… and suddenly you’re itchy, headachey, bloated, anxious, or sleeping like trash.

This Reel is **not** a “be good” lecture. We’re not doing restriction or diet culture here.
It’s just a few **low-effort, realistic tips** to help you enjoy the season *and* stay as functional as possible.

Think: **freshness not perfection**, **pace yourself**, and **choose what matters most** (because you deserve joy *and* a nervous system that isn’t on fire).

If you want the full deep dive on histamine + hormones + ADHD + hypermobility + gut health + meds, it’s on my blog (link in bio).

Festive events without diet talk: a small change that makes gatherings safer 🎄

Festive season is meant to feel connecting. But for a lot of people, it turns into a low-key performance review of bodies and plates.

Even when it's framed as a joke, a compliment, or "I'm just being honest", diet talk and body commentary can increase stress at the table, trigger shame and rumination, keep everyone stuck in body surveillance, and make meals and photos feel less safe.

And no — you can't tell someone's health by looking at them.

**What counts as diet talk?**
"I'm being good/bad" | "I'll have to work this off" | "Are you sure you want that?" | "You look amazing — have you lost weight?" | New Year "reset" / detox / punishment plans

**What to say instead (simple scripts)**

*Soft redirect:*
"I'm trying to keep food talk neutral today — how have you been?"
"Can we park diet chat? Tell me what you've been into lately."

*Clear boundary:*
"I'm not doing weight or diet talk."
"I don't discuss bodies — mine or anyone else's."

*Exit plan:*
"I'm going to grab some air — back in a bit."

Leaving isn't rude. It's regulation.

If you've got a go-to phrase that shuts down diet chat without drama, drop it in the comments — I'm collecting scripts people can actually use. 💚

Endometriosis and iron: why you're probably deficient

If you have endometriosis, there's a good chance your iron levels are low—even if your doctor says your bloods are "normal."

Heavy bleeding = iron loss. Month after month. Year after year.

Low iron doesn't just mean fatigue. It means brain fog, breathlessness, dizziness, hair loss, and worsening pain sensitivity.

Your body can't make iron. You have to replace what you lose.

Healthy Foods That Are Surprisingly High in Histamine (Histamine Intolerance)

Some “healthy” foods can still be surprisingly high in histamine—or can trigger histamine release. And if you’ve got histamine intolerance / MCAS vibes, that can feel like your body is beefing with you for no reason.

In this Reel I’m talking through **common healthy foods that are often higher in histamine**, plus why reactions can feel inconsistent (freshness, storage time, leftovers, and your personal threshold all matter).

This isn’t about fear-mongering food or cutting everything out forever. It’s about **pattern-spotting** so you can have better conversations with your healthcare team and make choices that actually match your body.

Want the full deep dive on how histamine links with **hormones, ADHD, hypermobility, gut health, and medications**? Head to my blog (link in bio).
