Ingredients
Vitamin K is the name of a group of compounds: phylloquinone (vitamin K1), found mainly in green leafy vegetables, and the menaquinones (vitamin K2), which are mostly of bacterial origin and occur in modest amounts in animal-based and fermented foods. Vitamin K is needed to make proteins involved in blood clotting and bone metabolism.[4]
Vitamin D occurs in foods and supplements mainly as D2 (ergocalciferol) and D3 (cholecalciferol). It promotes calcium absorption in the gut and is needed for normal bone mineralisation, bone growth and bone remodelling; the body also makes it when sunlight strikes the skin.[5]
How to use
- Dose: 1 capsule a day.
- How: with some liquid.
- Do not: exceed the recommended daily dose, or use the supplement as a substitute for a varied and balanced diet and a healthy lifestyle.
- Storage: in a cool, dry place, protected from light and out of the reach of young children.
Precautions
As a food supplement it is not a medicine and is not meant to treat, prevent or cure diseases. People who are pregnant or breastfeeding should talk to a health care provider before starting the supplement. The same applies to anyone on medication. Children should be given the supplement with caution, except when a health care provider has recommended this product.[6]
- People who take any blood thinner should ask a doctor before use.[1] Vitamin K can interact seriously with anticoagulants such as warfarin, which work against vitamin K; people taking them need a consistent intake of vitamin K from food and supplements.[4]
