Overview
Actium D3 Capsules 25,000 IU are a high-dose Vitamin D3 (cholecalciferol) loading preparation providing 25,000 International Units (625 micrograms) of Vitamin D3 per capsule. This is a clinical loading dose product intended for use under the supervision and direction of a GP or healthcare professional. It is not for routine daily supplementation — the 25,000 IU dose is approximately six times the NHS adult safe upper daily supplementation limit, and is used specifically in medical practice for the accelerated correction of severe Vitamin D deficiency, typically on a weekly or fortnightly dosing schedule under blood test monitoring. The 12-capsule pack size is consistent with a standard 6–8 week loading regimen.
Vitamin D deficiency is common in the UK — estimated to affect approximately 20–25% of the population, with higher rates in older adults, those with darker skin, those who are housebound, and those with malabsorption conditions. Where mild to moderate deficiency may be addressed with standard supplemental doses (400–2,000 IU/day), severe deficiency requires more rapid correction — clinically this is typically achieved through loading doses of 25,000–100,000 IU taken weekly or on an agreed schedule, followed by a maintenance dose thereafter. Vitamin D3 (cholecalciferol) contributes to the normal function of the immune system, maintenance of normal bones and teeth, normal muscle function, and normal calcium and phosphorus absorption — EU/UK approved health claims.

Actium D3 25,000 IU Capsules are available from Pearl Chemist Group. Individuals who are considering Vitamin D supplementation for general health without confirmed severe deficiency should consider standard-dose preparations — browse the full Vitamin D supplement range at Pearl Chemist Group.
How to Take — Actium D3 Capsules 25,000 IU
For use ONLY as directed by your GP or healthcare professional. Do not take without explicit medical direction. [CONFIRM approved dosing regimen from label — a typical loading protocol is one 25,000 IU capsule per week for 6–8 weeks, followed by GP reassessment and maintenance dose.]
Take with a meal containing fat — Vitamin D3 is fat-soluble and absorption is significantly enhanced when taken with dietary fat. Swallow whole with water.
After completing a loading course: Your GP will advise on appropriate ongoing maintenance dosing (typically 800–2,000 IU/day) and repeat blood testing to confirm adequate Vitamin D status.
Key Ingredient — Actium D3 Capsules 25,000 IU
| Ingredient | Per Capsule | What It Does |
|---|---|---|
| Vitamin D3 (Cholecalciferol) | 25,000 IU (625 micrograms) | The naturally occurring form of Vitamin D, produced by skin from sunlight and the form most efficiently converted to active calcitriol in the kidneys. At this loading dose, raises blood 25(OH)D levels rapidly when taken on a supervised weekly or fortnightly regimen. EU/UK approved contributions: normal immune function, normal bone maintenance, normal muscle function, normal calcium/phosphorus absorption. |
⚠ Medical Supervision Required — Important Safety Information
Actium D3 25,000 IU Capsules must only be used under the supervision and direction of a GP or healthcare professional. This is a loading dose preparation — not for routine daily supplementation. Do not take these capsules daily. Do not take more than one capsule without explicit direction from your GP. Vitamin D toxicity (hypervitaminosis D) from excessive use causes hypercalcaemia — a potentially serious condition. Blood calcium levels should be monitored during and after a loading course as directed by your GP.

Storage — Actium D3 Capsules 25,000 IU
Store in a cool, dry place below 25°C, away from direct sunlight and heat. Light and heat can degrade Vitamin D3 — store in a dark cupboard throughout the course. Keep in the original packaging.

FAQs
Why are loading doses used for Vitamin D deficiency?
When Vitamin D blood levels (25-hydroxyvitamin D) are severely depleted, standard daily supplementation doses of 400–2,000 IU/day restore levels very slowly — potentially taking many months. Loading doses of 25,000–100,000 IU taken weekly or fortnightly deliver a rapid increase in blood Vitamin D levels, correcting severe deficiency far more quickly than daily low-dose supplementation. The loading approach is then followed by a maintenance dose under GP direction.
Why is this a 12-capsule pack?
A typical clinical loading protocol for severe Vitamin D deficiency involves one 25,000 IU capsule per week for 6–8 weeks (or one fortnightly for 12 weeks), followed by GP reassessment. The 12-capsule pack is sized to accommodate standard loading course durations under GP direction. The exact protocol will be specified by your GP or prescribing healthcare professional.
Who is this product for?
Actium D3 25,000 IU is for adults with severe Vitamin D deficiency confirmed by blood test, who have been directed by their GP to undertake a loading dose regimen. It is not appropriate for those who are supplementing for general wellness, preventive purposes, or mild insufficiency — standard-dose preparations (400–2,000 IU/day) are appropriate for those purposes.
Can I take one capsule every day?
No. Do not take these capsules daily. At 25,000 IU per capsule, daily use would deliver approximately 175,000 IU per week — nearly 44 times the NHS safe upper daily limit and would rapidly cause Vitamin D toxicity. This product is specifically for weekly or less frequent loading regimens under medical supervision.
What happens after a loading course is complete?
After completing the loading course, your GP will request repeat blood testing to confirm that Vitamin D levels have been adequately restored. They will then advise on an appropriate ongoing maintenance dose — typically in the range of 800–2,000 IU per day — and a schedule for periodic blood test monitoring to ensure levels remain in the optimal range.
