What are vitamin D3 K2 MSM capsules?
This is a three-ingredient capsule: vitamin D3 (cholecalciferol), vitamin K2 (menaquinone-7) and MSM (methylsulfonylmethane). Vitamin D3 is the form your skin makes from UVB sunlight, and it is the form the NHS identifies as the more effective at raising vitamin D levels. Vitamin K2 MK-7 is the long-chain form of vitamin K2 that stays in circulation longer than MK-4 (Schurgers & Vermeer, 2002). MSM is a sulphur compound found naturally in small amounts in foods.
Most people looking to buy vitamin D3 K2 capsules UK are comparing strength. Ours is a high-strength capsule, so we print the full figures and tell you how to use it safely. Many UK sellers list “high strength” without stating the dose. We would rather you knew exactly what is in it.
UK guidance is that adults need 10µg (400 IU) of vitamin D a day in autumn and winter, when sunlight is too weak for the skin to make enough (Holick, 2007). Twice-weekly use of this capsule gives an average of about 71µg a day, comfortably above that and below the 100µg upper level.

First-time buyer guide
- Start with 30 capsules. At twice a week that lasts about 15 weeks.
- Pick two fixed days, such as Monday and Thursday, so you never double up.
- Take it with food that has fat in it. Vitamins D and K are fat-soluble.
- Check your other supplements. If a multivitamin already contains vitamin D, count it in your total.
- On warfarin? Speak to your doctor first.

Authorised health claims, explained in plain English
✅ Vitamin D contributes to normal absorption/utilisation of calcium and phosphorus
Vitamin D is converted in the body into calcitriol, a hormone that switches on the gut proteins which take calcium and phosphorus out of food. “Normal” means keeping that absorption working as it should, not pushing it above normal.
✅ Vitamin D contributes to normal blood calcium levels
The body holds blood calcium inside a narrow range because nerves, muscles and the heart rely on it. Vitamin D is one of the signals that keeps it there. This is about maintaining the normal range, not raising calcium.
✅ Vitamin D contributes to the maintenance of normal bones
Bone is rebuilt constantly. Vitamin D makes sure calcium and phosphorus from food are available for that rebuilding. The claim covers keeping healthy bone healthy, not treating any bone condition.
✅ Vitamin D contributes to the maintenance of normal muscle function
Muscle cells have vitamin D receptors and depend on calcium to contract. Vitamin D supports that ordinary contraction process. It is not a strength or performance claim.
✅ Vitamin D contributes to the maintenance of normal teeth
Teeth are built from calcium phosphate minerals, and vitamin D keeps those minerals supplied. It is about maintaining teeth, not repairing damage.
✅ Vitamin D contributes to the normal function of the immune system
Many immune cells carry vitamin D receptors and use vitamin D in their ordinary signalling. “Normal function” means the immune system working as it should, not boosting it or preventing any illness.
✅ Vitamin D has a role in the process of cell division
When cells copy themselves to replace worn-out tissue, vitamin D is one of the factors that helps regulate the process. This describes a basic biological role, nothing more.
✅ Vitamin K contributes to normal blood clotting
The liver makes clotting proteins that only work once vitamin K has activated them. That activation is the step warfarin blocks, which is why anyone on warfarin must check with their doctor first. “Normal” clotting means ordinary clotting, not thicker blood.
✅ Vitamin K contributes to the maintenance of normal bones
Bone-building cells make a protein called osteocalcin, which can only bind calcium into bone once vitamin K has activated it. The claim covers maintaining healthy bone, not treating bone loss.
The three ingredients
☀️ Vitamin D3: cholecalciferol
The form made in the skin from sunlight and found in oily fish and egg yolks. 10,000 IU (250µg) per capsule. Fat-soluble, so take it with a meal containing fat.
🦴 Vitamin K2: menaquinone-7
The long-chain K2 form found in fermented foods such as natto. 450µg per capsule. A long half-life suits a twice-weekly dose. Interacts with warfarin.
⚪ MSM: methylsulfonylmethane
An organic sulphur compound present in small amounts in milk, fruit and vegetables (Butawan et al., 2017). 600mg per capsule. No authorised health claim exists for MSM, so we make none.
🤝 Why D3 and K2 together
Both vitamins carry the authorised claim for maintenance of normal bones, and both need dietary fat to be absorbed, so one capsule with a meal covers both.

Frequently asked questions
How much vitamin D3, K2 and MSM is in each capsule?
Each capsule contains 10,000 IU (250µg) vitamin D3 as cholecalciferol (5000% NRV), 450µg vitamin K2 as menaquinone-7 (600% NRV) and 600mg MSM (methylsulfonylmethane, no NRV).
How often should I take 10,000 IU vitamin D3 capsules?
Take one capsule twice a week with a meal containing fat, for example Monday and Thursday. That averages about 2,860 IU (71µg) a day, below the 4,000 IU (100µg) daily level the NHS describes as safe for most adults. Do not take one every day unless your GP has advised it.
Why not take a 10,000 IU capsule every day?
10,000 IU is 2.5 times the 4,000 IU (100µg) daily upper level used by the NHS and EFSA. Taken daily over long periods, high doses can raise blood calcium too far (hypercalcaemia). Twice-weekly use keeps the average intake within that level.
Can I take this if I am on warfarin or other blood thinners?
No, not without your doctor’s advice. Vitamin K affects how warfarin and similar anticoagulants work. Speak to your GP or pharmacist before use if you take any blood-thinning medication.
Is this product vegan or vegetarian?
The capsule shell is HPMC (hydroxypropyl methylcellulose), which is plant-based and gelatin-free. We do not claim vegan for the finished capsule yet, because vitamin D3 is most often made from lanolin (sheep’s wool) and we are confirming the source with our supplier. We will update this page once that is confirmed.
What is MK-7 and why is it used?
MK-7 (menaquinone-7) is a long-chain form of vitamin K2. It stays in circulation longer after each dose than the short-chain MK-4 form, which suits less frequent dosing.
What does MSM add?
MSM (methylsulfonylmethane) is a naturally occurring sulphur compound found in small amounts in foods. It has no authorised health claim in the UK, so we make none for it. It is included as a sulphur source and listed by weight.
Why take D3 and K2 together?
Vitamin D and vitamin K both carry the authorised claim for maintenance of normal bones, and both are fat-soluble, so one capsule taken with a meal containing fat covers both.
What is the difference between vitamin D3 and D2?
Vitamin D3 (cholecalciferol) is the form the skin makes from sunlight. Vitamin D2 (ergocalciferol) comes from plant and fungal sources. The NHS notes D3 is the more effective of the two at raising vitamin D levels.
Is this product a medicine?
No. Vitamin D3, K2 and MSM capsules are a food supplement, not a medicine, and are not intended to diagnose, treat, cure or prevent any disease.
Which pack size should a first-time buyer choose?
At twice a week, 30 capsules lasts about 15 weeks and 60 capsules about 30 weeks. Most first-time buyers start with 30 to check they get on with the capsule size.
How fast is UK delivery?
Orders placed before 3:30pm Monday to Friday are dispatched the same day from UK stock in Southend-on-Sea. Delivery is free on orders over £10.
Can I buy vitamin D3 K2 capsules wholesale in the UK?
Yes. We supply bulk vitamin D3 K2 MSM capsules to retailers, gyms, clinics and resellers from UK stock. Contact us through the trade enquiry page for MOQ and pricing.
Do you offer white-label or private-label D3 K2 capsules?
Yes. We encapsulate in-house in Southend-on-Sea and can supply unbranded or private-label packs. Ask through the trade enquiry page.
Can trade buyers get a Certificate of Analysis?
Yes. A supplier Certificate of Analysis covering heavy metals and microbiology is available to trade buyers on request.
Who should not take this product?
Not for under-18s, anyone pregnant or breastfeeding, anyone taking warfarin or other anticoagulants, or anyone with kidney disease, kidney stones, sarcoidosis, hypercalcaemia or high blood calcium, unless advised by their doctor.
