What Is Vitamin K2 MK-7?
Vitamin K exists in two main forms: K1 (phylloquinone) and K2 (menaquinone). Amongst the K2 subtypes, MK-7 (menaquinone-7) is the most studied due to its long half-life and sustained activity. Solgar's K2 is sourced from natto extract, a wholefood that naturally provides MK-7. This form is prized for superior absorption and its role in calcium metabolism. Compared to synthetic versions, wholefood sources offer additional cofactors that may enhance bioavailability.
Key Benefits of Vitamin K2
Vitamin K2 supports several aspects of health by activating proteins that regulate calcium deposition. Key benefits include:
-
Bone Health: Supports osteocalcin production, which helps bind calcium to bone matrix, potentially maintaining bone density and strength with age.
-
Cardiovascular Support: Activates matrix Gla-protein (MGP) to prevent calcium build-up in arteries, supporting healthy blood vessel function.
-
Synergy with Vitamin D: Works with vitamin D3 to direct calcium to bones and teeth rather than soft tissues. Many experts recommend taking them together.
-
Wholefood Source: Derived from natto, this supplement provides naturally occurring MK-7 that may be more easily utilised by the body than synthetic forms.
Who May Benefit from Vitamin K2 Supplementation?
Vitamin K2 is not widely available in typical Western diets, as it is found mainly in fermented foods like natto, certain cheeses, and organ meats. Individuals who may benefit include:
- People with limited intake of fermented foods
- Those concerned about bone health, especially post-menopausal women
- Individuals taking vitamin D supplements, as K2 helps optimize calcium utilisation
- Older adults who may have reduced K2 absorption
As always, consult with a healthcare professional before starting any new supplement regimen.
