That first coffee of the day doesn’t create energy. It borrows the appearance of it, and the bill for that energy comes due later in the day. In this blog we will look at how caffeine works, why caffeine isn’t supporting your energy authentically, and 5 realistic strategies that will.

What caffeine actually does
In order to understand how caffeine works, let’s look at what is actually happening in the body. Throughout the day, a molecule called adenosine builds up in your brain. The more it accumulates, the sleepier you feel. It’s your body’s own tiredness signal, working exactly as designed. Caffeine doesn’t clear that adenosine or top up any depleted energy reserve. It blocks the receptors that would normally read the signal, so your brain stops registering how tired you actually are, even though nothing about your underlying fatigue has changed. You feel sharper because the alarm has been muted, not because the cause of the alarm has been dealt with.
If you’re someone who reaches for a second or third cup by early afternoon to keep you going, this is worth reflecting on. The exhaustion underneath, whatever’s driving it, is still there. You’ve just stopped being able to feel it.
The caffeine crash
Caffeine also pushes up cortisol and adrenaline, our key stress hormones, and in regular caffeine users research shows us that stress hormone response can become even more pronounced over time. Cortisol is one of the hormones that governs alertness across the day, so when caffeine keeps nudging it up on a schedule your body didn’t choose, energy stops following a steady curve and starts moving in spikes and drops instead.
So your 3 pm energy crash may not be a separate problem from your morning caffeine intake. It’s the same mechanism, playing out a few hours later, and every top‑up cup only resets the clock on when the next dip arrives.
Five places to put your attention instead
So rather than relying on caffeine to prop up your energy, here are 5 areas I would focus on to address underlying fatigue:
1. Protect sleep quality and consistency
Caffeine cannot replace restorative sleep. Aiming for 7-8 hours of quality sleep every night is a fundamental pillar of supporting your energy levels. Equally as important is sleep consistency - going to bed and waking at similar times, weekdays and weekends both, can do more for how you feel by mid‑afternoon than an extra 45 minutes of sleep grabbed inconsistently. Prioritise a consistent wind‑down routine and wake time, dim lights 60–90 minutes before bed, and keep caffeine at least 8–10 hours before bedtime to avoid fragmenting deep sleep.
If you wake unrefreshed despite “enough” hours, look at your sleep environment, alcohol, late meals, and stress which can commonly undermine sleep quality. If sleep is something you struggle with, Extracted’s Sleepee is a gentle formulation designed to help you get a restorative night’s rest.
2. Hydrate early and often
Even mild dehydration can reduce alertness and cognitive performance. Start the day with a large glass of water and sip regularly through the morning. Many people feel a noticeable lift simply by correcting a fluid deficit before reaching for caffeine.
If you’re training, sweating heavily, or simply not retaining what you drink, an electrolyte formula such as Hydree could be a good option to support fluid balance.
3. Eat enough and build balanced meals
Under‑eating or skipping meals reads to your body as scarcity, and it responds by conserving energy rather than spending it freely which is a fast track to energy dips. Aim for meals that combine:
- Protein (eggs, fish, tofu, legumes, meat) to stabilise blood sugar and support neurotransmitters
- Fibre‑rich carbs (oats, berries, squash, beans, vegetables) for steady glucose
- Healthy fats (olive oil, nuts, seeds, avocado) for satiety and hormone support
This combination keeps your blood sugar stable and your body fuelled thereby reducing the likelihood of an energy crash. Plan regular meals so you’re not relying on stimulants to bridge long gaps.
4. Prioritise a varied whole food diet
Key nutrients for cellular energy include iron (especially for menstruating women), B vitamins (B12, folate, B6), magnesium, and vitamin D. Iron carries oxygen to your cells, B vitamins help convert food into usable energy, magnesium is involved in hundreds of enzymatic reactions your body relies on to produce that energy. Prioritising a varied, wholefood diet ensures you are keeping these crucial nutritional stores topped up.
Modern diets and modern stress levels both increase demand while doing nothing to increase supply.
This is where a quality multivitamin such as Multee and a proper Magnesium Complex may be useful: not as a substitute for food, but as insurance against nutritional gaps. If fatigue is persistent, especially in menstruating women, consider discussing targeted testing (iron studies, B12, folate, vitamin D, thyroid) with your GP.
5. Move your body strategically
Regular movement improves mitochondrial function (the energy producing parts of your cells), insulin sensitivity, and stress resilience, all of which support daytime energy. Even though it may feel counter-productive when you are lacking in energy, research has shown that low‑intensity exercise reduces fatigue symptoms by up to 65 percent.
You don’t need gruelling sessions: a brisk 10 - 20 minute walk after meals, short mobility breaks, or light resistance work can lift energy without provoking a crash. If you’re already over‑trained or burned out, scale intensity and prioritise recovery - more isn’t always better.
A note on stress
None of the above will hold if the mental load underneath it never gets addressed. Chronic stress keeps your body in a state physiologists call ‘allostatic load’- the cumulative wear of a system that never fully stands down- and it’s been linked to measurable changes in brain structure and hormone regulation over time.
You can eat well, sleep on schedule, and still run on empty if your nervous system never gets the signal it’s safe to come off high alert.Build small down‑regulation habits into your day: two to three minutes of slow breathing with longer exhales, a short walk outside, or a screen‑free pause before your next meeting. These practices reduce perceived effort and can blunt the urge to use caffeine as a coping tool.
Next time the 3pm slump hits
Before the fourth coffee, ask what it’s actually telling you. Sometimes it’s water. Sometimes it’s the meal you skipped, or the bed you didn’t get to on time, or a stress load that’s been building for longer than today. The fatigue was never really about caffeine. It was always about what caffeine was covering up.

How does Multee work?
Our revolutionary supplement works by combining everything your body needs in optimum dosages, so you won’t need to buy other supplements separately - it’s all included in these two daily capsules!
How long does it take to notice a difference with Multee?
With Multee, you should see noticeable results within just 30 days of consistent usage, although individual experiences may vary.
Multee should start to make a noticeable impact on your energy levels and overall wellbeing after one month. But based on the most recent studies, it can take 1-3 months of consistent usage to correct a vitamin deficiency - it can vary depending on your diet and overall health condition. Some people may feel the benefits sooner than this, but response times can differ based on factors like overall health status and whether or not they've stuck to the recommended dosage.
Please note, the B vitamin complex can cause bright yellow urine - this is nothing to worry about!
Can I combine Magnesium Complex with your other supplements?
Is magnesium safe to take long term?
Yes, our Magnesium Complex is safe for long-term use when taken as directed. Magnesium is an essential mineral that plays a crucial role in many bodily functions. However, if you have any medical conditions or are on medication, it’s always best to consult your doctor before long-term use.
