Why Am I So Tired? 5 Reasons You’re Lacking Energy (That Your Blood Tests Might Miss)

Are you constantly asking yourself, "Why am I so tired all the time?"

You’re not alone — and you’re definitely not lazy. If you’re a woman aged 25–45 juggling work, family, and everything in between, running on empty can feel like your new normal.
But just because something is common doesn’t mean it’s normal. If your energy levels are in the bin and your blood tests come back “fine,” here are 5 root causes of fatigue I commonly see in clinic — and what you can do about them.

1. Your Gut Health Is Out of Balance

Your gut is where you absorb nutrients, regulate inflammation, and even make energy-supporting vitamins like B12 and iron. If you're dealing with bloating, reflux, constipation, or loose stools, your energy levels are probably taking a hit too.

Poor digestion = poor absorption = low energy.

Gut symptoms to watch for:
Bloating after meals
Irregular bowel movements
Feeling full quickly or sluggish digestion

What can help:
A herbal formula tailored to your gut, simple food swaps, and improving stomach acid can make a world of difference in your energy. I help my clients get back to basics and build energy from the inside out.

2. Your Hormones Are Out of Whack

Feeling more tired before your period? Struggling with motivation around ovulation or getting a second wind at night?

Hormonal imbalances like low progesterone, oestrogen dominance, or thyroid dysfunction can all cause major energy crashes.

Clues your hormones are draining you:
PMS, heavy periods or irregular cycles
Waking around 2–4am
Fatigue worse in the luteal phase (after ovulation)

What can help:
Herbs like peony, chaste tree, and licorice can support hormonal balance — but only when matched to your individual cycle and symptoms.

3. You’re Wired but Tired (aka Nervous System Overload)

If you feel exhausted during the day but can’t sleep at night, or wake up more tired than you went to bed — your nervous system could be running the show.

High stress = high cortisol = burnout.

Signs your stress response is tapped out:
Anxiety or irritability
Racing thoughts or insomnia
Relying on caffeine to get going

What can help:
Adaptogenic herbs like withania or rhodiola, nervous system tonics like lemon balm or passionflower, plus setting simple daily rituals to calm your system and recharge.

4. You’re Not Getting Restorative Sleep

Getting enough sleep and getting restorative sleep aren’t the same. If you’re tossing and turning, waking multiple times, or dreaming intensely every night, your body isn’t getting the deep repair it needs.

Common culprits:
Blood sugar imbalances
Night-time cortisol spikes
Low magnesium or GABA

What can help:
Balancing blood sugar through dinner/snacks, herbal sleep support, and reducing blue light before bed can all help reset your rhythm.

5. You’re Nutrient Depleted (Even if You Eat "Healthy")

You can eat all the greens in the world, but if your digestion is off or stress is depleting you, key nutrients like iron, B12, magnesium and zinc can run low — even if your bloods are “within range.”

Symptoms to watch for:
Dizziness or lightheadedness
Restless legs
Muscle twitches or brain fog

What can help:
Functional blood analysis (which I offer), practitioner-quality supplements where needed, and personalised herbal formulas to support better absorption.

So... What Can You Do About It?

Start by listening to your body.

Tiredness is a message — not something to ignore or push through. Whether it’s your gut, hormones, stress levels or sleep, the root cause matters.
