FAQ

Find the most frequently asked questions below.
  • This product can be taken alongside our Inositol Infusion, Magnesium Glycinate or Iron & Energy Restore. When used as directed, the combined vitamin D intake across our range remains below the UK and EU tolerable upper intake level of 4,000 IU per day.

    If you are pregnant, breastfeeding, or taking anticoagulant medication (such as warfarin), consult your healthcare professional before taking this product.

  • Vitamin D helps the body absorb calcium from the diet.

    Vitamin K contributes to the maintenance of normal bones and to normal blood clotting.

    Including vitamin K2 alongside vitamin D reflects how these nutrients work in the body’s normal physiology, particularly in relation to bone health.

    Vitamin K2 helps activate proteins involved in directing calcium to where it is needed, such as the bones, as part of normal bone maintenance. This is why vitamin D and vitamin K are often considered together in supplement formulations designed to support overall bone health.

    This formula provides vitamin K2 in a stable, bioavailable form to complement vitamin D intake within safe, regulated levels.

  • Take one capsule daily with food, especially with food rich in healthy fats to aid absorption.

  • If you are pregnant, breastfeeding, or taking any medication, consult a healthcare professional before use.

    Vitamin K may interfere with anticoagulant medication (such as warfarin); if you are taking these medicines, seek medical advice before supplementing.
