About This Product.

Thorne Vitamin D-1,000 provides 1,000 IU (25 mcg) of vitamin D3 as cholecalciferol — the same form your skin produces in sunlight, and the form most efficiently converted to active vitamin D in the body. Each capsule also contains a small amount of vitamin E as a natural antioxidant to help protect cells from oxidative stress and preserve the formula's stability. Vitamin D is one of the most commonly identified nutritional shortfalls in the UK, particularly between October and March when UVB exposure is too low for the body to produce its own. Even during summer months, those who work indoors, wear sunscreen consistently, or have darker skin tones are at higher risk of insufficiency. A blood test measuring 25-hydroxyvitamin D is the only reliable way to know where you stand — supplementing without one means guessing.

At 1,000 IU per capsule, this is a sensible maintenance dose for adults whose levels are already within normal range and who want to stay there. Those correcting a confirmed insufficiency may need a higher daily intake under clinical guidance — the capsule format makes it straightforward to adjust the number taken per day based on your results and your practitioner's recommendation.

How to Take It

i.

Take 1 capsule daily with a meal containing some fat, or as directed by your healthcare professional. Vitamin D is fat-soluble, so absorption improves when taken alongside dietary fat — even a small amount is sufficient. Those supplementing at higher doses (2–3 capsules daily) should do so under clinical guidance, ideally with periodic blood monitoring to track 25-hydroxyvitamin D levels and avoid over-supplementation. Store in a cool, dry place away from direct sunlight. Keep out of reach of children.

Solid everyday vitamin D

4 months ago

Been taking one of these every morning since October when my GP mentioned my levels were on the lower end of normal. Nothing dramatic to report — which is probably the point. Just keeping things topped up through the winter months. The capsules are small and easy to swallow, no aftertaste. At £15 for 90 capsules it's genuinely good value.

Does exactly what it says

6 months ago

Had my vitamin D checked last autumn and was told to supplement through winter. Take one with breakfast and have honestly noticed I feel less run-down than previous winters. Could be placebo, could be this — either way I'll keep buying it.

Good quality but wish there were more per bottle

8 months ago

Quality seems solid and I trust this brand from other supplements I've used. My only gripe is that 90 capsules goes faster than you'd think when you're taking two a day on practitioner advice — means you're reordering every six weeks or so. Would really prefer a 180-capsule option at this dose. Price per capsule is fair, just the bottle size that's slightly inconvenient.
