Vitamin D3 helps the body absorb calcium, while K2 ensures it’s directed to the bones, not soft tissues like arteries. Together, they support proper calcium usage and bone strength.

Yes, our Vitamin D3 is plant-based (from lichen) and K2 is derived from natto, making the product 100% vegan.

We use natural MK-7 from fermented soybeans (natto), known for its superior bioavailability.

One pouch contains 365 tablets — a full year’s supply with just one a day.

A: Yes. The tablets are small 8mm and are designed for easy daily use with no aftertaste.

Yes, 4000 IU is the tolerable upper limit set by EFSA for adults. It’s within safe daily intake levels. Consult a healthcare professional if you have specific concerns.

Take with a meal containing fat, as both D3 and K2 are fat-soluble vitamins. Morning or afternoon is ideal.

Yes. The tablets contain no pork-derived ingredients, no alcohol, and use vegetable-origin magnesium stearate. The product is listed in our halal supplements range.

Identical vitamin D3 molecule and potency. The difference is the source — lichen is plant-based, making it suitable for vegans. Lanolin comes from sheep’s wool.

Yes. Vitamin D3 + K2 works well alongside most other supplements. Avoid taking with high-dose calcium supplements at the same time without medical advice.

Many people in the UK still don’t get enough Vitamin D even in summer, particularly if they spend most of the day indoors, wear sunscreen, or have darker skin. Public Health England recommends supplementation year-round for those at risk of deficiency.

Common signs include fatigue, muscle weakness, bone pain, frequent illness, and low mood. The NHS estimates that around 1 in 5 adults in the UK have low Vitamin D levels. A blood test from your GP can confirm deficiency.

Vitamin D3 (cholecalciferol) is the same form your body produces from sunlight. Research shows D3 raises and maintains blood levels of Vitamin D more effectively than D2 (ergocalciferol). D3 is also more stable and has a longer shelf life.

K1 is primarily involved in blood clotting. K2 MK-7 has a different role — it activates proteins that direct calcium into bones and teeth and away from soft tissues like arteries. MK-7 also stays active in the body much longer than K1 or the MK-4 form of K2.

If you are taking anticoagulant medication such as warfarin, consult your doctor before taking any supplement containing Vitamin K2. K2 can affect how blood-thinning medications work. This does not apply to most other medications.

4000 IU is suitable for most adults and is the upper safe limit set by EFSA. If you have been diagnosed with severe deficiency, your GP may recommend a higher loading dose for a short period. For general maintenance, 4000 IU daily is a well-supported dose.

Soft gels typically use oil-based delivery and often contain gelatine. Our tablets use a compressed dry form with no gelatine, making them vegan-friendly. Both forms are effective, but tablets are easier to manufacture without animal-derived ingredients.
