The picks in depth

1

Vitabiotics Vitamin D 1000 IU Tablets 90-pack

⭐ NHS recommended

The UK government recommends all UK adults consider a daily 10 mcg (400 IU) vitamin D supplement, especially October-March. 1000 IU gives comfortable margin.

💡 Editor's note: UK sunlight doesn't contain enough UVB for adequate vitamin D synthesis from October to March — even in southern England. This is the most evidence-backed supplement recommendation in UK healthcare.
2

Cleanmarine Omega-3 Krill Oil 500mg

Best omega-3

Omega-3 (EPA/DHA) from krill, no fishy aftertaste, 60 capsules. Evidence base for heart health, inflammation, mental health.

💡 Editor's note: Omega-3 from oily fish (or supplements) has genuine evidence for cardiovascular health and inflammation markers. Krill oil has better bioavailability than fish oil and no fishy taste or burps.
3

BiOptimizers Magnesium Breakthrough

Best magnesium

7 forms of magnesium, highest bioavailability blend. Evidence for sleep quality, muscle function, glucose metabolism.

💡 Editor's note: Magnesium is the supplement most likely to give a noticeable effect — deficiency is common in UK adults (soil depletion, modern diet). The glycinate and malate forms have the best evidence for sleep and muscle recovery respectively.

What to look for

UK-specific evidence: Vitamin D is the NHS's only mass-recommendation supplement for the general population. Beyond that: omega-3 if you eat no oily fish, magnesium if you're active, creatine if you strength train. Most other supplements have weak or no evidence for healthy adults.

Frequently asked

?

Should I take a multivitamin?

The NHS doesn't recommend multivitamins for most healthy UK adults eating a balanced diet. The evidence that multivitamins improve health outcomes is weak. Specific targeted supplements (vitamin D in winter, omega-3, folate in pregnancy) have better evidence than broad-spectrum multivitamins.

?

How much vitamin D should UK adults take?

NHS recommendation: 10 mcg (400 IU) daily, especially October to March. The safe upper limit is 100 mcg (4,000 IU) per day. People with darker skin, who rarely go outside, or who cover up may need higher amounts — consult a GP if uncertain.
