NUTRITION • WEIGHT LOSS
The number on the scale is going down. So why do you feel worse?
Your appetite shrank. The list of things your body needs every day didn't. Three meals used to cover it without you thinking about it once, and now there's less food doing the same job.

For the first time in years, it's quiet. No negotiating with yourself at four in the afternoon. No running the numbers on what you ate. The food noise stopped.
Then one morning there's hair in the drain. Not a few strands. A handful.
Maybe for you it's not the hair. It's nails that snap where they used to bend. A 3pm slump you never used to hit. Catching your own face in the mirror and thinking, why do I look so tired? Everyone keeps telling you how good you look. Nobody has explained why you feel like this.
You're not imagining it. And you're not doing anything wrong.
So why is this happening?
Nothing has gone wrong. Your appetite is doing exactly what it's meant to. The trouble is that the nutrients shrink with the amount you eat.
Food isn't just calories. It's iron, B12, zinc, biotin – what your hair and your energy are built from. Eat half as much food and you get half as much nutrients too.
Your body isn't daft about it. When less comes in, it keeps the lights on where it matters – heart, lungs, blood – and cuts everywhere else. Your hair goes first. Then your energy. Then the sharpness you can't quite put your finger on. Nothing is broken. Your body is rationing.
Which explains the strange contradiction anyone on a big weight-loss journey will recognise: the better the scale looks, the rougher you may feel. It's not the weight loss that's the problem. It's the gaps.
"Losing weight quickly is one of the most nutritionally demanding things a body can do. Most people are doing it with nobody watching the nutrition side at all."
— Heights Science & Research Team
Okay — so what do you actually do about it?
Ask any dietitian who works with people losing weight fast and you'll get the same three answers, in roughly the same order:
1
Protein, at every meal
Your muscles don't know you're dieting on purpose. Protein tells them to stay. When your portions are small, protein goes first on the plate.
2
Resistance training, twice a week
You don't need a gym membership. You need to give your muscles a reason to stay. Two sessions a week is the difference between smaller and stronger.
3
Micronutrients, covered daily
The vitamins and minerals your meals used to cover don't fit in a smaller appetite. This is the part thats harder to manage.
The first two you've heard before. The third is where most people end up winging it: a biotin gummy because someone on TikTok swore by it, iron because you felt tired, a B12 spray from the chemist just in case. Before long the counter looks like a pharmacy, it's costing £100 a month, and you still don't know whether any of it is going in.
That's where Vitals⁺ comes in
20 essential nutrients – the full B complex, omega-3 from algae, vitamin D3, vitamin E, iron, zinc, selenium, iodine – in two small capsules. One simple habit to stick to, not several.
Two things that make Vitals different from standard multivitamins: The capsules are delayed-release, which means the nutrients survive your stomach acid and get to where they need for your body to absorb them. And there's nothing else in them. No fillers, no bulking agents, none of the padding cheaper brands use. Just nutrients in their active forms, the ones your body can use as-is.

Does it actually work, though?
Fair question. Every supplement on the shelf says it's "backed by science", and you've probably been let down by that before.
Vitals⁺ went through a 12-week randomised, double-blind, placebo-controlled trial – 35 adults in London and Manchester, run by third-party laboratory the Functional Gut Clinic, with blood analysis completed at Ulster University and The University of Sterling. It was presented at the Nutrition Society conference in spring 2026. You can read more about the study here.
That's more than almost any multivitamin on the shelf has ever done.
The first thing that turned up wasn't about the product at all. Ordinary healthy adults were already running low. 40% short on folate. 34% short on active B12. 83% low on riboflavin. Before any weight loss entered the picture. After 12 weeks:

That's in people eating normal amounts. You can guess where you'd be starting from.

One thing it won't do
Vitals⁺ won't lose the weight for you. That's not what it's for.
It's there for the part of weight loss that's easier to overlook: making sure that eating less doesn't automatically mean getting less of what your body needs.
2 capsules cover 20 essential nutrients to help you feel more like yourself again – supporting your energy and giving your hair, skin and nails more of what they need too.
Because you didn't sign up for a smaller, more tired version of yourself. You wanted to lose the weight. Not yourself.
2 capsules a day. 1 less thing to worry about.
The vitamins and minerals you need, in 2 small capsules. Delayed-release, so they get where they need to.

Questions? We've got answers
What's the difference between this and the multivitamin I'm already taking?
Mostly the ingredient list and the doses. Vitals⁺ has 20 nutrients in it, including the ones that get hardest to cover when you're eating less: iron, B12, folate, iodine, zinc, vitamin D. Most supermarket multivitamins cover a shorter list. There are also no fillers, colourants or caffeine in it.
I'm not eating much. Will two capsules on a near-empty stomach be a problem?
They're built for exactly that. The capsules are double-walled and delayed-release, so they open past your stomach rather than in it. Take them with a glass of water or juice, with food or without, whenever you remember. First thing works for most people because it's one less thing to forget.
Is this a subscription? And how hard is it to stop?
It's a monthly subscription, and it's genuinely one tap in your account to skip a month or cancel. No email, no phone call, nobody asking you to reconsider. UK shipping is free.
When would I notice anything?
Honestly, not immediately. Nutrient levels shift over weeks, not days, and we'd suggest giving it three months before you judge it. You've got 30 days to get a refund if you decide it isn't for you, which is a shorter window than that on purpose. Try it, don't force it.
I'm taking something my doctor prescribed. Is this okay alongside it?
We always recommend checking with your doctor or healthcare profressional if you have any questions or concerns at all.
What's actually in it, and what isn't?
20 vitamins and minerals plus omega-3 from algae. Vegan, and free from all 14 major allergens, including gluten, dairy, soy and nuts. No fillers, no colourants, no caffeine. The full ingredient list is on the product page if you want to read it properly.
