Supplements and medical nutrition, explained without the hype
From everyday vitamins to feeding at home, we cut through the marketing so you can choose what actually helps — and skip what doesn't. Educational guidance, never a sales pitch.
What this hub covers
Walk into any pharmacy or scroll any health website and you'll be told you need dozens of pills, powders and shakes. The truth is quieter: most people who eat reasonably well need very few supplements, a handful of groups genuinely benefit from specific ones, and a smaller number depend on medical nutrition prescribed and monitored by their care team.
Our job is to help you tell those apart. We review categories and what to look for — not named products — so you can read a label, weigh a claim and ask your GP, pharmacist or dietitian the right questions. This is general information, not medical advice: for anything personal, speak to a health professional.

Four plain-English guides, from everyday vitamins to clinical nutrition at home. Start wherever your question sits.
Choosing vitamins & minerals
Who actually benefits, which UK groups the NHS advises to supplement, and how to avoid paying for things you don't need. Vitamin D, folic acid in pregnancy, B12 and more.

What home tube feeding involves, the kit you'll meet, hygiene and safety basics, and the support services that should be wrapped around you.
Read the guide SWALLOWINGHydration, thickeners & oral nutrition
The IDDSI framework explained, when thickened fluids and oral nutritional supplements are appropriate, and why they should follow a speech & language therapist's assessment.

Whatever the category, the same handful of checks separate a sensible buy from wasted money — or worse.
A clear %NRV figure
Reputable products state the Nutrient Reference Value per dose. NRV replaced the old 'RDA' in UK/EU labelling — same idea, newer name. No %NRV usually means no useful information.
Stays within safe upper levels
UK industry works to Safe Upper Levels from the 2003 Expert Group on Vitamins and Minerals. Mega-dose 'more is better' products can do harm, especially fat-soluble vitamins like A and D.
Honest, permitted claims
Only certain health claims are legally allowed. Anything promising to treat or cure a disease strays into medicines territory regulated by the MHRA — a red flag on a food supplement.
A real need behind it
The strongest case for a supplement is a known gap: a deficiency, a life stage like pregnancy, a restricted diet, or a condition affecting absorption. 'Just in case' rarely justifies the cost.
No replacement for food or advice
Supplements top up a diet; they don't fix a poor one. And nothing here replaces a conversation with your GP, pharmacist or dietitian about your own circumstances.
It's easy to assume nutrition is all about adding supplements. But across UK health and care settings, around 45% of adults screened have been found at risk of disease-related malnutrition, and the condition is estimated to cost UK health and social care many billions a year. For older adults, people recovering from illness and those with swallowing difficulties, the right oral nutritional support or feeding plan can matter far more than any vitamin pill — which is why those decisions belong with a dietitian or your care team, not a shop shelf.
Common questions
Does everyone in the UK need a vitamin D supplement?
The NHS suggests most people consider 10 micrograms of vitamin D a day during autumn and winter, when sunlight is limited, and some at-risk groups — people with darker skin, those who are housebound, and anyone covering up outdoors — may benefit year-round. It's one of the few supplements with broad official backing. Check current NHS advice and speak to a pharmacist if unsure.
Are 'medical nutrition' products the same as supplements?
No. Oral nutritional supplements (the prescribed shakes and powders), enteral feeds and thickeners are clinical products used under professional guidance — often after a dietitian or speech & language therapist assessment. They are not the same as the food supplements you buy off the shelf, and shouldn't be self-prescribed.
Why won't you recommend specific brands?
Because we're a watchdog, not a shop. We don't sell, take commission or accept products. Naming 'best buys' invites bias and goes stale fast. Instead we teach you the criteria — read those, then choose for yourself or with your pharmacist.
Choose with confidence, not pressure
Read the category guides, learn what the labels really mean, and signpost the NHS, a GP or a pharmacist for any decision about your own health.
