Life Stage

Nutrient needs change with age, though less dramatically than most product labels suggest. Two things genuinely shift. The first is how much of a nutrient your body needs. The second is the form you can realistically take and absorb. A one-year-old needs drops from a pipette. A fast-growing teenager mainly needs calcium and iron from food, with a supplement only filling the gaps. Someone of seventy often does better with a vitamin B12 form that does not depend on strong stomach acid. Age is a useful starting point, not a diagnosis.

One UK recommendation applies at almost every age: vitamin D. The Department of Health and Social Care advises 10 micrograms, or 400 IU, a day for children from one year old and for adults. Babies and children aged 1 to 4 should take it all year round. Everyone else is advised to consider a daily supplement in autumn and winter, because British sunlight is too weak from October to March. The vitamin D3 products we stock are therefore the busiest corner of this collection.

Growing bodies and older bodies ask for different things

For children and teenagers, food comes first and a supplement fills gaps. Fussy eating, a vegan diet or a heavy sports timetable are the usual reasons parents end up here. Our selection for teenagers stays with modest doses, since children reach safe upper limits much sooner than adults. Later in life the reasoning flips. Absorption of vitamin B12 falls with age, appetite often shrinks, and interactions matter more. Vitamin K, for instance, affects how the blood thinner warfarin works, so speak to your GP or pharmacist before you start.

Form decides whether a supplement is actually taken

• Drops: for babies and toddlers, dosed with a pipette or on a spoon.
• Chewables and gummies: for children who refuse tablets. We prefer versions without added sugar.
• Capsules and tablets: the standard adult choice and usually the lowest cost per day.
• Liquids and sprays: helpful when swallowing large tablets becomes a nuisance, which is why they feature in our range for over-55s.

How we choose per life stage

We judge three things: the form, the dose and whether the combination makes sense for that age. In practice that means drops with a clear microgram figure per pipette, chewables without added sugar, and no adult-strength multivitamin simply relabelled for children. We are brand-neutral: we stock what delivers, not what pays us most, and we only carry brands we stand behind. Every product passes our compliance team, we test products ourselves, and independent labs spot-check batches. After more than ten years, we would rather explain why we left something out. Read how we select.

Keep expectations realistic. Most people notice nothing in the first days; with daily use, allow two to three weeks, and some nutrients simply keep a normal function ticking over without a felt effect. If you would rather shop by what you want to support, such as bones, sleep or resistance, start from our overview of health goals instead of your age.
