Our vitamin D3 & vitamin K2 stands out as a superior, plant-based dietary supplement offering a range of benefits:

Bone Health:

  • Vitamin D3 helps the body absorb calcium, which is crucial for strong bones and teeth [1].
  • Vitamin K2 activates proteins that help direct calcium into bones and teeth, preventing it from accumulating in soft tissues [2].

Heart Health:

  • Vitamin K2 is thought to help reduce the build up of calcium in the arteries, potentially lowering the risk of arterial calcification, a risk factor for heart disease [3].

Immune System Support:

  • Vitamin D3 is important for immune function and may help protect against infections [4].
  • Vitamin K2 may play a role in immune regulation [5].

Dental Health:

  • Both vitamins D3 and K2 contribute to healthy teeth by supporting proper mineralisation [6].

Reduced Risk of Osteoporosis:

  • The combination of vitamin D3 and K2 can help prevent the loss of bone density and reduce the risk of osteoporosis [7].

Cognitive Health:

  • Some research suggests that these vitamins may have a role in cognitive function and brain health [8].

Mood and Mental Health:

  • Vitamin D3 has been associated with improved mood and a reduced risk of depression [9].

Reduced Inflammation:

  • Both vitamins have anti-inflammatory properties that can benefit overall health [10].

Skin Health:

  • Vitamin D3 plays a role in skin health, potentially aiding conditions like psoriasis and acne [11].

There are two types of Vitamin D that are important for nutrition: Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol). Vitamin D3 is more effective at raising and maintaining adequate levels of circulating Vitamin D in the body, making it the preferred choice for supplementation. [12]

Our supplement ensures you get the best, most absorbable form of Vitamin D paired with K2 for optimum bone health and immune support.

Our Vitamin K2 MK-7 is a bioactive form of Vitamin K, known for its remarkable ability to support bone and heart health. By aiding in the activation of important proteins, it ensures calcium is effectively directed to bones, promoting both strength and stability.

We use vitamin K2 MK-7 over the more commonly used MK-4 in most brands. MK-7 has superior bioavailability and remains in the body for an longer duration compared to other forms of vitamin K2. [13]
