D3 4000iu by LSC, 60 High-Strength Capsules

D3 4000iu, High-Strength Vitamin D for the Winter Months

If you're a UK adult and it's October to March, you're not making vitamin D from sunlight. The angle of the sun isn't strong enough this far north. Most of us walk around with levels well below optimal for half the year, which is why D3 is one of the supplements we recommend most often in the shop. LSC D3 4000iu is the high-strength daily option, 60 capsules per bottle, one a day with food.

Why 4000iu

4000iu is the strength most adults actually use as a daily D3, particularly through the darker months. High enough to lift levels meaningfully, well within sensible daily intake. If you'd rather have something gentler, our standard D3 + K2 combination is a step down with the K2 alongside. If you want to know your actual starting level, the LSC Bloods and Beyond service uses venous blood testing to give you real numbers to work from.

Vitamin D contributes to the normal function of the immune system. Vitamin D contributes to the maintenance of normal bones, normal teeth, and normal muscle function. Those are the authorised GB nutrient claims, and they're why we keep a steady stock of D3 on the shelf year-round.

Who it's for

• UK adults through the autumn and winter months, when sunlight exposure drops
• Older customers, who synthesise vitamin D less efficiently from sunlight
• Indoor workers and shift workers who don't get much daylight
• People building an immune support routine through the colder months
• Anyone whose blood-test levels have come back low and wants a high-strength daily option

What's different about it

The LSC house range is built around functional doses and clean labels. 4000iu is the meaningful daily strength rather than the tiny token amounts you'll see in cheap supermarket multivitamins. The capsule is small, the label is clean, and the form is the one we'd take ourselves.

How to take it

One capsule daily, with food, because vitamin D is fat-soluble and absorbs better alongside a meal. Easy to stack with a daily B12, magnesium, or any of the other LSC daily basics. Pair it with the wider Immunity range or our Vitamins & Minerals collection if you're rounding out your basics.
