Vitamin D3 helps your body absorb calcium, while Vitamin K2 helps direct that calcium to your bones where it’s needed. Together, they support normal bone health more effectively than Vitamin D3 alone.

MK-7 is a highly bioavailable form of Vitamin K2 with a longer half-life in the body compared to MK-4. This means it stays active for longer and can be taken in lower, once-daily doses.

400 IU (10 mcg) is a common recommendation for daily vitamin D supplementation.

However, studies have shown that this is not sufficient for many people. 4000 IU is a more potent and effective dose, which is still within the safe limits.

While it is true that Vitamin D toxicity can become an issue, this is generally for doses of 10,000 IU or more per day over a prolonged period of time.

Of course it is always best to check with your GP for your specific situation, but 4000 IU is a perfectly safe dose for most people.

Most supermarket quality Vitamin D is made from cheap synthetic ingredients. We’ve gone further to find sustainable, plant-based ingredients.

For example, our Vitamin D is in the form D3 rather than D2 for higher effectiveness and we’ve removed palm oil from the formula.

Our D3 is sourced from plant-based Lichen extract, rather than the animal-based Lanolin or fish used in most other D3 supplements.

We have a high-strength 4000iu dose and offer a 3-month supply rather than the usual 1-month supply.

No — this formula is designed for adults due to the higher strength of Vitamin D3 (4000 IU). Children require different dosages appropriate to their age.

Most multivitamins contain small amounts of Vitamin D and/or K. Taking this product alongside them is usually fine, but always check the combined daily intake and consult your healthcare provider if unsure.

Vitamin D is commonly recommended during pregnancy, but Vitamin K2 supplementation varies by individual needs. Pregnant or breastfeeding women should consult their midwife or GP before taking a combined supplement.

Vitamin D3 is fat-soluble, so it’s best absorbed with a meal or snack containing healthy fats. Morning or lunchtime works well for most people.

This varies between individuals. While some may feel an improvement in energy or mood within weeks, bone-related benefits take longer as calcium metabolism adapts. Most people take Vitamin D3 + K2 for long-term maintenance.

Yes — many people remain low in Vitamin D even through summer due to modern indoor lifestyles, sunscreen use, and limited midday sun exposure. Daily supplementation helps maintain consistent levels year-round.
