Feeling energised all day isn’t about chasing the next caffeine hit, it’s about creating an internal environment where every cell can do its job efficiently. And that’s exactly why we’ve created the Energy Starter Kit. This bundle addresses three often-overlooked pillars of energy which when addressed together, make a noticeable difference: balanced blood sugar, optimal hydration, and sufficient Vitamin D3. When these systems run smoothly, you get steady energy production, better craving control, sharper focus, and a more resilient mood. It's also running with our best off yet: for a limited time you can get all the above plus a free ARTAH Scoop for just £45 (down from £90). Here’s why it works.
Blood-Sugar Balance: Your Source of Stable Energy
Rapid swings in glucose can leave you buzzing one moment and exhausted the next. Emerging continuous glucose monitor research in healthy adults and athletes shows that bigger day-to-day glycaemic variability is correlated with subjective fatigue and poorer performance; in simple terms, the more unstable your blood sugar, the more fatigued you are (1). Why does this happen? Mechanistically, unstable blood sugar stresses mitochondria (the powerhouse of the cell) and accelerates the release of counter-regulatory hormones, tipping you toward the dreaded afternoon slump.
Lifestyle cue: Build meals around protein, fibre, and quality fats. Use carbohydrates as a side, not the main event, and consider time them around activity. If you have a sweet tooth, adding sugar is one of the fastest ways to bring blood sugar back into balance – but it is often easier said than done, which is one of the reasons we love Metabolic Fix. It blends berberine, chromium (which helps maintain normal blood-glucose levels), alpha-lipoic acid, and green-tea catechins to support smooth glucose uptake and sustained energy [2]. Add in a brisk post-meal walk and you’ll give your cells an extra boost in shuttling glucose where it belongs.
Hydration: The Stress Trigger That Affects Everyone
Even mild dehydration (think 1%) can affect how your brain and body function. As little as a 1–2% drop in hydration can elevate cortisol, the body’s primary stress hormone, and increase the perception of fatigue [3]. In fact, studies in healthy adults show that low fluid intake is linked to reduced alertness, poor mood, and increased tiredness—even in the absence of physical activity [4]. Because hydration plays a central role in oxygen transport, temperature regulation, and nutrient delivery, it has a ripple effect on energy levels throughout the day.
Lifestyle cue: Think beyond plain water and use electrolytes to help drive fluid into cells for smooth energy production. Cellular Hydration supplies magnesium, potassium, maca, and inulin to rehydrate, support the microbiome, and keep energy steady without added sugars or artificial sweeteners. Add 1 scoop to your large water bottle and drink throughout the morning, during workouts or in the afternoon to help prevent the thirst fatigue that masquerades as hunger.
Vitamin D3: One of the Biggest Health Influencers of All Time
By now, you’ve probably heard that Vitamin D is important to just about everything. It’s the pre-hormone that influences virtually every aspect of our health, and in the UK, we don’t get enough of it. Vitamin D receptors sit on muscle, immune, and brain cells, and sub-optimal levels are now linked to higher rates of fatigue and low mood. A 2025 dose-response meta-analysis of 42 randomized clinical trial reported that correcting deficiency meaningfully improved depressive symptoms, especially at daily doses ≥2,000 IU [7]. Other reviews tie low vitamin D to persistent tiredness across chronic conditions [8] and note modest immune benefits—though recent work shows effects may depend on baseline status and dose [9].
Lifestyle cue: Aim for sensible mid-day sun exposure an consider a high-quality D3/K2 supplement taken with food. As a fat-soluble vitamin, the fat in the meal boosts absorption.
Combine adequate D3 with stable glucose and daily hydration and you’ve covered three of the most science-backed levers for all-day energy.
