Are multivitamins a waste of money?

It depends on the gap. Large RCTs in generally healthy populations (PHS-II, COSMOS) have reported small or null effects on cardiovascular events, cancer, and all-cause mortality. The strongest case for a multivitamin is gap-filling for individuals with a plausible reason to be short — restricted diets, certain medical conditions, older age, pregnancy. For someone with a varied NHS-Eatwell-aligned diet and no specific deficit, the trial evidence does not support broad-spectrum supplementation as a measurable endpoint shifter. The most consistent positive signal is on cognitive decline in older adults (COSMOS-Mind, Baker et al.) over 2–3 years.

What does the NHS recommend?

NHS guidance is targeted rather than blanket. It recommends 10 micrograms (400 IU) vitamin D daily for everyone aged 4+ from October to March, and year-round for those at higher risk. It recommends 400 micrograms folic acid daily for women planning pregnancy and through the first 12 weeks. It flags vitamin B12 for vegans and older adults, and iron for women with heavy periods (under GP supervision). The NHS Healthy Start scheme provides free vitamins to qualifying pregnant women and young children. The NHS does not recommend a daily multivitamin for healthy adults eating a varied diet.

Should I take a multi if I eat well?

The trial evidence does not strongly support general multivitamin use in adults eating a varied NHS-Eatwell-aligned diet. The exceptions where the literature points to specific gaps even in people who think they eat well are: vitamin D (most UK adults in winter), folate (women planning pregnancy), iron (women with heavy periods), B12 (vegans, older adults), and iodine (vegans, young women on low-dairy diets). Targeted single-nutrient supplementation matched to the specific gap is closer to what the evidence supports than a broad-spectrum multi. A registered dietitian or GP can help identify whether a specific gap exists.

Are gummies as effective as tablets?

Generally no, for full-spectrum gap-filling. Gummies typically omit iron (chemical and taste reasons), cap calcium and magnesium below RNI levels, and run lower B-vitamin doses. Independent label audits have found gummies under-deliver vitamin C and A versus their label more often than compressed tablets, partly because of nutrient degradation in the gummy matrix. Each gummy serving also contains 1–4 g sugar or polyol. For broad coverage, tablets and capsules are better tools. Gummies can be reasonable for single-nutrient products focused on D3 or a small B-complex.

Best multivitamin for women in the UK?

Nutripedia does not recommend specific brands as a treatment. The literature-supported features for a women's multi in the UK are: iron around 14 mg (matching the UK RNI for women 19–49); vitamin D3 10–25 mcg (400–1000 IU); folate 200–400 mcg, especially for women planning pregnancy; B12 at or above NRV; and iodine 140 mcg. UK products covering this profile include Vitabiotics Wellwoman (and the Pregnacare range for pregnancy), Centrum Women, and Boots and Holland & Barrett own-brand women's formulas in the £6–£15 per 30-day range. A blood test for iron and ferritin is more informative than guessing — heavy menstrual blood loss is the single most common reversible cause of low ferritin in UK women.

Are 'food-state' multis better?

The independent evidence is thin. 'Food-state' or 'whole-food' multivitamins claim superior bioavailability through plant or yeast matrices. The trials supporting this claim are small, often industry-funded, and typically use surrogate markers rather than hard endpoints. A 2012 Cochrane review on synthetic vs natural vitamin E found no meaningful clinical difference. EFSA does not currently authorise health claims distinguishing food-state from synthetic forms. The 2–4× price premium for food-state multis is not robustly justified by independent evidence.

Best Multivitamin UK (2026): What's Worth the Spend

Nutripedia Research Team14 April 2026

Updated 30 April 2026

Multivitamins are the most-bought and least-studied supplement category. We summarise SACN and NDNS data on UK micronutrient gaps, the trial evidence on hard endpoints, and the practical questions that decide whether a multi is worth the spend.

What a Multivitamin Actually Is — And Why That Matters

A multivitamin is not a single supplement. It is a packaging decision: a fixed combination of vitamins (and usually some minerals) at doses chosen by the manufacturer rather than by the individual's diet. That makes the buyer's question different from a single-nutrient supplement. The relevant comparison is not 'does vitamin C work' — it is 'does this specific combination at these specific doses, taken on top of my actual diet, close a gap I actually have'. **Disclaimer.** Nutripedia summarises published research. We do not provide medical advice. Consult a UK GP, NHS pharmacist, or registered dietitian before starting any supplement, especially if pregnant, breastfeeding, on medication, or managing a chronic condition. Multivitamins can interact with prescription medications (notably warfarin via vitamin K, levothyroxine via calcium and iron, and some antibiotics). This guide is structured around what the UK evidence base actually says: the SACN and NDNS data on real UK micronutrient gaps, the trial evidence on whether multis change endpoints that matter, the form-factor question (gummy vs tablet vs capsule), and the life-stage formulas (women, men, prenatal, over-50). The aim is to help readers make a better-informed conversation with their GP or registered dietitian, not to recommend a specific product unsupervised.
