How to Choose a Multivitamin: A Buyer's Guide That Actually Helps

You've been told by everyone — from your GP to your gym friend — that "you should probably take a multivitamin". Fine. You walk into the high street pharmacy, see 30 bottles, and walk out with whatever has the cheerful pensioner on the front. That decision was made by the marketing team, not by you. Here's how to actually pick one in five minutes.

Multivitamins range from £3 to £45 a bottle. The active-ingredient differences inside are real — but rarely advertised on the front. The label is where the truth lives, and once you know what to look for, the choice is fast.

1. Active forms over cheap forms

This is the single biggest quality marker. Look for:

The label names the form of each nutrient, for example folic acid or methylfolate.

2. No mega-doses

A good multi sits at 100–200% of the UK NRV (Nutrient Reference Value) for most vitamins. Higher than that is wasted on water-soluble vitamins (you'll excrete it) and risky long-term for fat-soluble ones. The NHS advises 10 micrograms of vitamin D a day in autumn and winter.

3. The full B-complex shows up

A multi that lists all eight B vitamins (B1, B2, B3, B5, B6, B7/biotin, B9/folate, B12) at meaningful percentages is doing the basics right. B vitamins are water-soluble, so the body needs a daily resupply.

4. The minerals you actually miss are present

Check which minerals the label lists.

5. Transparent labelling — no proprietary blends

Some labels give each ingredient's amount; proprietary blends give the list only.

6. No unnecessary fillers

Some bulking agents are needed to make a tablet a tablet. But check for: titanium dioxide (E171, banned in the EU and Northern Ireland since 2022), aspartame, artificial colours, and excessive magnesium stearate. Cleaner formulas use rice flour, microcrystalline cellulose, or HPMC capsule shells.

7. Vegan, vegetarian, halal, kosher — clearly stated

Capsule shells matter. HPMC (vegetable cellulose) capsules are vegan-friendly. Gelatine capsules are not. If you avoid gelatine for any reason, this should be on the front of the label, not buried.

8. Made in the UK under UK food law.

Cheaper imported products may meet a different standard.

9. Demographic-appropriate

"One size fits all" multivitamins are a compromise. Women of reproductive age have different iron needs from post-menopausal women.

You don't need to read the back like a textbook. Run this checklist:

• D3, not D2 ✓

Premium multivitamins often include extras. The ones worth the upgrade:

• Live cultures: some multis add them; the label states the species and the count. Quality formulas like our Live Cultures Multi declare strain names and CFU counts.
• Our Ashwagandha Capsules combine ashwagandha, cordyceps and Panax ginseng with B vitamins.

The Vitadefence Vitamins Multi gives 17 vitamins and minerals (D3, K2 and others), live cultures and botanicals in a vegan HPMC capsule. Take 1 capsule, 1 to 3 times a day.

Picking a multivitamin should take five minutes, not five visits. Active forms over cheap forms, sensible doses, transparent labelling, GMP-made. Anything else is marketing.
