Vitamin D3 & K2

Vitamin D3 and K2 work together to support bone density, immune function and cardiovascular health. Vitamin D3 enhances calcium absorption from the digestive system, while K2 directs that calcium into bones and teeth and away from soft tissues such as arteries.

Each capsule provides 2500 IU of vitamin D3 as cholecalciferol, the same form your skin produces in response to sunlight. Research consistently shows D3 is more effective than D2 (ergocalciferol) at raising and maintaining blood levels of vitamin D.

The K2 in this formula is all trans MK 7, the most active and longest lasting form of vitamin K2. MK 7 remains active in the body for up to 72 hours, compared to just a few hours for the MK 4 form, which means it provides sustained support throughout the day.

In the UK, limited sunlight between October and March means most people do not produce enough vitamin D during the winter months. Public Health England recommends supplementation during this period. Many nutritional therapists advise year round use for those who spend most of their time indoors.

Vitamin D requires adequate magnesium to be properly activated in the body. If you are taking vitamin D at a higher dose, ensuring your magnesium intake is sufficient will help you get the most from it.

Take 3 capsules once per day with dinner.

Vitamin D is fat soluble, so taking it with a meal that contains dietary fat improves absorption by 30 to 50%. Evening dosing with your main meal is generally the most practical approach.

At 3 capsules per day, this provides 7500 IU of vitamin D3 alongside 600 mcg of vitamin K2. This is a therapeutic level of vitamin D, appropriate for those looking to maintain optimal levels or correct a shortfall.

If you are unsure of your current vitamin D status, a blood test for 25(OH)D through your GP or a home testing service is the most reliable way to check. This can help you and your healthcare practitioner determine whether a higher or lower dose is right for your needs.
