Support your calcium metabolism effectively with Oppuland’s Vitamin D3 and K2 formula. This advanced supplement combines high-potency vitamin D3 (as cholecalciferol) with vitamin K2 as MK-7 (menaquinone-7) to help ensure proper calcium absorption and utilisation. Thanks to liposomal technology, each soft gel capsule delivers 5000 IU of vitamin D3 and 100 µg of vitamin K2 MK-7 with superior bioavailability, contributing to strong bones, cardiovascular wellness, and overall health.*
Key Health Benefits
Bone Health: By promoting calcium absorption and directing it to the bones, this D3+K2 blend helps maintain bone density and strength. Particularly beneficial for ageing adults and those at risk of bone loss.
Cardiovascular Support: Vitamin K2 activates matrix GLA protein, which may help preserve arterial flexibility and prevent calcium build-up in soft tissues, supporting heart health.
Immune Function: Vitamin D3 contributes to the normal function of the immune system, helping the body defend against seasonal challenges.*
Dental Health: Proper calcium utilisation also supports tooth mineralisation and overall oral health.
Why Take Vitamin D3 and K2 Together?
Vitamin D3 and K2 work in synergy to manage calcium in the body. Vitamin D3 enhances calcium absorption from the digestive tract, while vitamin K2 directs that calcium to the bones and teeth where it belongs. Insufficient K2 may allow calcium to accumulate in soft tissues like arteries, potentially compromising cardiovascular health. This combination ensures calcium is used effectively for bone density and structural support, making it a valuable addition to any wellness routine.
Understanding the Synergy: How D3 and K2 Work Together
At the cellular level, vitamin D3 boosts the production of calcium-binding proteins that increase intestinal calcium uptake. Vitamin K2 then activates two key proteins: osteocalcin, which helps bind calcium to the bone matrix, and matrix GLA protein (MGP), which may inhibit calcium deposition in blood vessels. The MK-7 form of vitamin K2 is particularly advantageous due to its longer half-life in circulation, providing sustained support. This synergy helps maintain a healthy calcium balance throughout the body.
What to Look For in a D3 + K2 Supplement
When selecting a vitamin D3 and K2 supplement, consider dosage, form, and delivery. Oppuland’s formula provides 5000 IU of vitamin D3 and 100 µg of vitamin K2 as MK-7—a ratio many experts consider optimal. The K2 is in the MK-7 form, which offers superior bioavailability and a longer duration of action compared to MK-4. Additionally, this supplement uses advanced liposomal technology, which may enhance absorption by protecting nutrients during digestion. The softgels are free from unnecessary fillers and are easy to swallow, as noted by many users.
Recommended Dosage
As a food supplement, take one (1) soft gel capsule daily with a meal containing fat, as both vitamins are fat-soluble and absorption is enhanced with dietary fat. This provides 5000 IU of vitamin D3 and 100 µg of vitamin K2 MK-7. Do not exceed the recommended dose unless directed by a health care professional. Individual requirements may vary based on age, sun exposure, and health status. For personalized advice, consult your health care provider.
Frequently Asked Questions
What is the best time to take this supplement? Take one soft gel capsule daily with a meal containing fat to optimise absorption.
Can I take it with other supplements? Yes, it pairs well with calcium, magnesium, and omega-3s. However, avoid taking with high-dose vitamin A as it may compete for absorption.
Are there any side effects? Vitamin D3 and K2 are generally well tolerated. If you are on blood thinners like warfarin, consult your health care provider before taking supplementary vitamin K2.
Is this supplement vegan? Vitamin D3 is typically sourced from lanolin (sheep’s wool), so it is not vegan. Vitamin K2 MK-7 may be derived from natto or synthetic sources; check the label for specifics.
