You’re eating reasonably well. You’re not doing anything obviously wrong. But something still feels off — you’re tired by 3pm, you can’t switch off at night, your skin looks flat, your stomach is always doing something it shouldn’t be, and the gym sessions that used to feel good now just feel hard.
You’re not imagining it. And you’re not alone — these are the exact complaints driving millions of UK searches every month for specific supplements. Not multivitamins. Specific ones, for specific problems.
Here are the 7 that are actually making a difference — matched to the problem they solve.
Problem: “I’m exhausted in the gym but I’m showing up every day.”
The fix: Creatine Monohydrate
Here’s what’s happening: your muscles run out of their fast energy supply (ATP) within seconds of hard effort. The only supplement proven to replenish it faster is creatine. More creatine stored = more reps, more power, faster recovery between sets. It’s not a stimulant. It doesn’t make you jittery. It just means you can do more of the thing you already came to do.
What most people don’t know: creatine also helps your brain do the same thing. If you hit a wall mentally mid-afternoon, that’s the same ATP depletion happening in your head instead of your legs. Which is why searches for creatine aren’t just coming from gym-goers anymore — they’re coming from people who work long hours and can’t afford to fade by 2pm.
5g a day. Any time. Stir it into water or your morning drink — it’s unflavoured. That’s it. £33.99. Halal approved. UK made.
Problem: “I feel run down constantly, especially in winter.”
The fix: Vitamin D3 + K2 Liposomal Drops
If you live in the UK and you haven’t been supplementing vitamin D, the NHS says there’s a 1-in-5 chance you’re deficient. If you have darker skin, work indoors, or cover up for religious or personal reasons, those odds are significantly worse. Low vitamin D doesn’t just hit your immune system — it affects your mood, your energy, and how your muscles feel day to day.
The reason this one includes K2: vitamin D tells your body to absorb more calcium. K2 makes sure that calcium goes into your bones where it belongs, not floating around where it shouldn’t be. You need both together. Most people only take D3 alone.
These are liquid drops that absorb faster than capsules — no need to remember to take them with a fatty meal. Just a few drops in the morning. £29.99. Halal approved. Vegan. UK made.
Problem: “I lie awake for hours even when I’m shattered. My mind won’t stop.”
The fix: Magnesium 3 Complex
Racing thoughts at bedtime aren’t a personality trait. For a huge number of people they’re a magnesium problem. Magnesium is the mineral that tells your nervous system to calm down — it literally quiets the brain activity that keeps you wired when you should be winding down. Research suggests nearly half of UK adults aren’t getting enough of it from food alone.
The reason this one has three forms of magnesium (glycinate, malate and taurate) instead of one: each form does something slightly different. Glycinate is the one for sleep and calm. Malate helps with energy and muscle recovery during the day. Taurate supports your heart and nervous system. You get all three in one capsule, which means you’re not just sleeping better — you’re waking up feeling like you actually rested.
Take 1–2 capsules about an hour before bed. £12.99 for 90 capsules. Halal approved. Vegan. UK made.
Problem: “My skin looks tired. My hair is thinning. Nothing I put on my face seems to help.”
The fix: Marine Collagen Nourish
Here’s the honest reason your skincare isn’t enough on its own: the structure that gives your skin its bounce and your hair its thickness is built from the inside. It’s called collagen, and your body produces less of it every year from your mid-twenties onward. Creams sit on the surface. They can’t rebuild what’s being lost underneath.
Collagen taken as a powder drink gives your body the raw material to start making it again. This one has 9g per serving — the dose that studies show actually works — plus hyaluronic acid for skin hydration, MSM for joint comfort, and vitamin C which your body needs to actually use the collagen. It tastes like orange and mango. Mix it into water in the morning and that’s your whole beauty-from-within routine done.
Results take 8–12 weeks of daily use. Skin changes aren’t overnight — but they are real. £29.99 for 30 servings. Halal approved. UK made.
Problem: “I feel flat and slow in training. I’m drinking water but it’s not helping.”
The fix: Electro-Hidr8 Electrolytes
Water alone doesn’t hydrate you properly when you’re sweating. Your muscles need sodium, potassium and magnesium to contract properly — when those drop, you feel it as fatigue, cramps and that heavy, sluggish feeling that isn’t tiredness so much as your body not having what it needs to perform. It’s the same reason athletes have always used sports drinks, except this one has no artificial colours, no junk sweeteners, and actually has the right electrolyte levels rather than the cheap versions.
Mix it into water before, during or after training. It’s a berry flavour and it tastes genuinely good, not like a chemistry experiment. £18.99. Halal approved. UK made.
Problem: “My stomach is always bloated. I get ill all the time. Something just feels off with my gut.”
The fix: BioTic 20 Billion Probiotic
Your gut isn’t just for digestion. It controls about 70% of your immune system and produces most of your serotonin — the chemical that affects your mood. When the balance of bacteria in there is off (which it often is after antibiotics, a bad diet patch, illness, or just chronic stress), you feel it everywhere: bloating, irregular bowel habits, getting every cold going, and a low mood that doesn’t have an obvious cause.
A probiotic replants the good bacteria. This one has 20 billion live cultures across 8 strains — enough to actually make a difference rather than the token amounts in yoghurt drinks that mostly don’t survive stomach acid. Most people notice a difference in digestion within the first two weeks. The immune and mood benefits build over 4–8 weeks. £19.99 for 30 capsules. Halal approved. Kosher approved. Vegan. UK made.
Problem: “I take vitamin C tablets but I still get every cold going.”
The fix: Liposomal Vitamin C
Here’s the uncomfortable truth about standard vitamin C tablets: above a certain dose, your gut simply can’t absorb them properly. The excess gets flushed out — which is why high-dose tablets sometimes cause stomach discomfort, and why you can take 1,000mg and still feel like it’s doing nothing.
Liposomal vitamin C wraps the vitamin in a tiny bubble made of the same material as your cells. Instead of fighting through your gut wall, it gets absorbed directly. More gets in. No stomach issues. And this one also has rosehip and bilberry in it — both rich in the plant compounds that make vitamin C work even better. The orange flavour liquid is actually pleasant — you just take a 5ml spoonful in the morning. £25.99 for 60 days. Halal approved. Kosher approved. Vegan. Soy-free. UK made.
