What a UK diet usually misses
The gaps
Not everything. Four or five things, reliably.
A reasonable diet covers most of what you need. The ones it tends not to are vitamin D between October and March, magnesium, iodine if you avoid dairy and fish, and B12 if you eat little meat. That is the list a daily multivitamin should be built around — and most are not.
| Amount | Nutrient | Why |
|---|---|---|
| 25 µg | Vitamin D3 | Contributes to normal immune function and the maintenance of normal bones. |
| 200 mg | Magnesium | Contributes to the reduction of tiredness and fatigue. |
| 150 µg | Iodine | Contributes to normal thyroid function and normal cognitive function. |
| 100 µg | Vitamin B12 | Contributes to normal energy-yielding metabolism. |
What to avoid
Multivitamins with forty ingredients. Most are present at amounts too small to do anything, and they are there to lengthen the label.
Worth knowing
The NHS suggests everyone in the UK considers a vitamin D supplement from October to March. That one is not brand advice, it is government advice.
