Vitamin D3 + K2 tablets | 4000 IU & MK-7 | Pure Vitamins UK

Most D3+K2 supplements on the UK market are, frankly, an afterthought. Many standard high-street options top out at a modest 1000 IU with no K2 at all, or use cheap D2 alternatives or low-dose D3 with synthetic MK-4 the short-lived form your body clears in hours. We chose differently. 4000 IU of D3 alongside 100 µg of the long-chain MK-7 form of K2, because a formula that actually works requires ingredients that actually last.

✔ Vitamin D3 (Cholecalciferol) - The Real Thing, at a Real Dose

D3 is the form your body produces from sunlight and the only form worth putting in a supplement. At 4000 IU per tablet, this isn't a token gesture. Vitamin D3 contributes to the normal function of the immune system, the maintenance of normal bones and teeth, and normal muscle function. Many budget D3 products sit at 400–1000 IU enough to tick a box, not enough to meaningfully contribute to your daily needs, especially through a British winter.

✔ Vitamin K2 (MK-7 Form) - The Delivery Driver D3 Needs

Here's what most brands skip: D3 raises calcium absorption, but without K2, that calcium needs directing to the right places. We use the MK-7 form derived from fermented chickpea because it has a significantly longer half-life in the body than MK-4, the cheaper synthetic alternative found in many lower-cost formulas. At 100 µg, it contributes to the maintenance of normal bones and teeth and works in concert with D3 rather than leaving the job half-done. This is the pairing that makes the formula make sense.

✔ 5-Action Synergy - Not Found in Standard UK D3 Supplements

Together, Vitamin D3 and K2 (MK-7) in this formula contribute to:

• Normal function of the immune system
• The maintenance of normal bones and teeth
• Normal muscle function
• Normal absorption and utilisation of calcium and phosphorus
• The maintenance of normal blood calcium levels

Most UK single-ingredient D3 products support two or three of these functions at best. Combining D3 with MK-7 at meaningful doses costs more and requires more formulation care - which is exactly why most brands don't bother.

✔ No Fillers. No Cheap MK-4. No Shortcuts.

No magnesium stearate flow agents in excessive quantities. No titanium dioxide. No synthetic MK-4 dressed up as K2. No unnecessary binders or bulking agents. Just D3 and MK-7, in an easy-swallow vegetarian tablet with a clean, minimal excipient base. What isn't in here matters just as much as what is.

✔ Clean, Transparent, Premium-Crafted Supplement

• Manufactured in GMP-certified facilities and tested for purity and heavy metals
• Vegetarian tablets - suitable for most dietary requirements
• Non-GMO raw materials

You didn't come here for the cheapest option you came here for the right one.

Important notices for the Pure Vitamins team before publishing:

1. Excipients Replace the placeholder "Other Ingredients" list with your confirmed finished product spec sheet data. If this product genuinely contains no unnecessary excipients beyond essential manufacturing aids, the optional line "No unnecessary fillers. No binders. Nothing that shouldn't be there." may be added but only if the spec supports it.
2. K2 source Confirm whether your MK-7 is fermented-chickpea-derived or soy-derived. This determines whether a soy allergen declaration is legally required under UK FIR.
3. Vegan vs. vegetarian The packaging states "Vegetarian Tablets." Confirm all excipients and the tablet shell are vegan-certified before updating this claim.
4. 4000 IU dose At 2000% NRV, consider whether a "Do not exceed the stated dose" advisory line is appropriate here in addition to the label. It adds transparency and consumer trust.
