INFORMATION ON VITAMIN K2 (MenaQ7)
Vitamin K2 is a fat-soluble vitamin that exists as a series of menaquinones (MK-4 to MK-7). It activates vitamin K-dependent proteins involved in calcium regulation, blood clotting, and tissue mineralization.
Functions:
- Directs calcium to bones and teeth, reducing deposition in arteries
- Supports proper blood clotting
- Works synergistically with vitamin D and magnesium for skeletal integrity
- Modulates cellular signaling and gene expression
TAILORBLEND uses MK-7 for its longer half-life and better bioavailability compared to MK-4.
POPULAR USE & PUBLISHED BENEFITS bbbb
Vitamin K2 is commonly used to support:
- Bone health by activating osteocalcin and directing calcium into bones
- Cardiovascular health by preventing arterial calcification
- Dental health and tooth mineralization
- Nervous system function and cellular signaling
- Synergy with vitamin D for calcium metabolism
WHOLE FOODS
Animal Sources:
- Liver, egg yolks, cheese, butter
Plant-Based Sources:
- Fermented foods (natto, certain cheeses)
- Small amounts in vegetables and fermented soy products
RECOMMENDED USE
Synergistic Nutrients:
- Vitamin D3: Enhances bone and cardiovascular benefits
- Magnesium & Calcium: Work with K2 to support skeletal health
- Vitamin A: Supports bone metabolism and tissue health
Typical Dosages:
- Maintenance: 40–90 µg/day
- Functional support (bone/cardiovascular health): 100–120 µg/day
- Therapeutic (osteoporosis or arterial calcification support): 120–200 µg/day
- MK-7 preferred due to longer half-life and more consistent serum levels
- High doses may interact with anticoagulants (warfarin) — monitor INR carefully
- Generally safe at dietary and supplemental doses
- Individuals with bleeding disorders or on blood-thinning medication should consult a physician before supplementation
