💛 Vitamin D3 & K2 — EU/UK Authorised Health Benefits
Vitamin D3 and Vitamin K2 both carry EU/UK authorised health claims under Regulation (EC) No 432/2012. These are legally approved nutrient function statements — they apply to the nutrients, not to any specific product. All products are food supplements only and are not medicines.
☀️ Vitamin D3 (Cholecalciferol) — 7 Authorised Claims
| Authorised Claim | What This Means |
|---|---|
| Normal absorption & utilisation of calcium and phosphorus | Vitamin D3 is required for calcium absorption in the gut — its most fundamental physiological role in mineral metabolism. |
| Normal blood calcium levels | Vitamin D plays a key role in calcium homeostasis alongside parathyroid hormone regulation. |
| Maintenance of normal bones | Vitamin D3 is required for normal bone mineralisation through its role in calcium and phosphate availability and regulation. |
| Maintenance of normal teeth | Vitamin D3 supports enamel and dentine mineralisation through calcium and phosphate availability. |
| Normal function of the immune system | Vitamin D receptors are expressed on immune cells — D3 is involved in both innate and adaptive immune regulation. |
| Normal muscle function | Vitamin D receptors in muscle tissue support normal muscle contraction and physiological muscle function. |
| Normal cell division | The active form of D3 (calcitriol) acts as a steroid hormone influencing gene expression and normal cell cycle regulation. |
🦴 Vitamin K2 MK-7 — 2 Authorised Claims
| Authorised Claim | What This Means |
|---|---|
| Normal blood clotting | Vitamin K is a required cofactor for carboxylation of clotting factors II, VII, IX and X in the coagulation cascade. |
| Maintenance of normal bones | Vitamin K2 is a cofactor for carboxylation of osteocalcin — a bone matrix protein involved in calcium binding within bone tissue. |
⚠ Compliance notice: All claims above are EU/UK authorised nutrient function claims under Regulation (EC) No 432/2012. These relate to the individual nutrients Vitamin D3 and Vitamin K2 — not to any specific product. No medicinal, therapeutic or diagnostic claims are made. These products are food supplements only.
☀️ Vitamin D Deficiency in the UK — Why D3 Supplementation Is Widely Recommended
Vitamin D deficiency is one of the most extensively documented nutritional shortfalls in the UK population. Between October and early March, sunlight in the UK does not contain sufficient UVB radiation for the skin to synthesise Vitamin D — making dietary or supplemental sources the only practical way to maintain Vitamin D status during this extended period.
The NHS, Public Health England and the Scientific Advisory Committee on Nutrition (SACN) all recommend that UK adults consider a daily Vitamin D supplement throughout autumn and winter. SACN's 2016 report established a Reference Nutrient Intake (RNI) of 10mcg (400 IU) per day for the general UK population — with growing recognition that many individuals, particularly those with darker skin, limited sun exposure, or those who cover their skin, may benefit from higher supplemental amounts. Charge Products supplies Vitamin D3 at 1,000 IU, 5,000 IU and 10,000 IU — all as clearly declared food supplements with full specification transparency.
Vitamin D3 (Cholecalciferol) is the animal-derived form of Vitamin D — the same form produced in human skin upon UVB exposure. It is consistently shown to be more effective than Vitamin D2 (ergocalciferol) at raising and sustaining serum 25(OH)D levels.

⚠ High-Strength Vitamin D3 — Important Safety Information
- 10,000 IU (250mcg) is a high-strength dose — the UK NRV for Vitamin D is 5mcg (200 IU). 10,000 IU represents 5,000% NRV. Long-term intake at this level should be discussed with a healthcare professional.
- Vitamin D toxicity (hypervitaminosis D) can occur from prolonged excessive intake — it is caused by supplementation, not sun exposure. Symptoms include hypercalcaemia, nausea and weakness.
- Do not combine multiple high-strength Vitamin D supplements without professional guidance.
- Individuals with conditions affecting calcium metabolism (e.g. sarcoidosis, hyperparathyroidism) should consult a doctor before taking Vitamin D supplements.
- Products containing Vitamin K2 should not be taken alongside warfarin or anticoagulant medications without medical advice — see warning above.
- Not suitable for children under 18 without healthcare guidance. Pregnant or breastfeeding individuals should consult a healthcare professional.

❓ Frequently Asked Questions — Vitamin D3 Supplements UK
Is 10,000 IU of Vitamin D3 safe?
10,000 IU (250mcg) is considered a high-strength dose — it is 5,000% of the UK NRV (5mcg/200 IU). The UK's Tolerable Upper Intake Level for Vitamin D has not been formally established by SACN, but the EFSA sets an adult UL of 100mcg (4,000 IU) per day. Long-term intake at 10,000 IU should be discussed with a qualified healthcare professional, particularly before combining multiple Vitamin D-containing supplements.
Why is Vitamin K2 combined with Vitamin D3?
Vitamin D3 and Vitamin K2 are both fat-soluble vitamins involved in calcium regulation. D3 promotes calcium absorption from the gut; K2 (particularly MK-7) acts as a cofactor for carboxylation of osteocalcin and matrix Gla protein, which are involved in directing calcium to appropriate physiological destinations. Both carry separate EU/UK authorised claims for maintenance of normal bones. Several products in this range combine both nutrients for this reason.
Can I take Vitamin D3 if I am on warfarin?
Standalone Vitamin D3 (without K2) does not directly interact with warfarin. However, products in this range that contain Vitamin K2 MK-7 can affect warfarin and anticoagulant medications. Always check the product page for K2 content and consult your doctor or pharmacist before taking any Vitamin K-containing supplement if you are on warfarin or any anticoagulant.
What is the difference between Vitamin D3 and Vitamin D2?
Vitamin D3 (Cholecalciferol) is the animal-derived form — the same form produced in human skin upon UVB sunlight exposure. Vitamin D2 (Ergocalciferol) is plant-derived. Research consistently shows Vitamin D3 is more effective at raising and maintaining serum 25-hydroxyvitamin D levels in the blood. All Vitamin D supplements supplied by Charge Products use Vitamin D3 (Cholecalciferol).
Are these Vitamin D3 products medicines?
No. All Vitamin D3 products from Charge Products are food supplements only — not licensed medicines and not regulated by the MHRA as medicinal products. They carry EU/UK authorised health claims for Vitamin D3 and Vitamin K2 under Regulation 432/2012 — as listed above — but are not medicines.
What is MSM and why is it in the D3 K2 MSM capsule?
MSM (Methylsulfonylmethane) is an organosulphur compound — a source of bioavailable sulphur. It is included in the D3 + K2 + MSM combination capsule formula as an additional ingredient alongside Vitamin D3 and K2 MK-7. MSM is a food supplement ingredient — no EU/UK authorised health claims exist for MSM under Regulation 432/2012. Its presence and amount is declared on the individual product page.
