Bone health; Calcium utilization; Vascular health
Adults who consume little dietary vitamin D or have limited sun exposure, and those looking for simple daily support for bone and vascular wellness.
Take 1 capsule once daily with a meal that contains fat; fat helps improve absorption of vitamin D3 and K2.
Kosher; Halal; Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, or sesame ingredients; Produced in a GMP facility that processes other allergens.
Vitamin D3 supports calcium absorption in the gut and helps regulate calcium and phosphate balance for bone mineralization.
Caution: Take with a meal containing fat to aid absorption; high intakes may be unsuitable for those with high calcium levels or on certain medications as it can raise blood calcium.
MK-7 activates proteins such as osteocalcin and Matrix Gla Protein that help direct calcium into bones and away from soft tissues.
Caution: Avoid use with warfarin or other vitamin K–antagonist anticoagulants because it can affect clotting tests.
Vitamin D3 increases calcium absorption, while MK-7 helps activate proteins that guide calcium into bone tissue. Together they support efficient calcium use for structural and vascular wellness.
Label Warning: Use vitamin D cautiously if taking cardiac glycosides or if you have high blood calcium. Vitamin D may interact with atorvastatin and thiazide diuretics. Vitamin K is contraindicated with warfarin or other anticoagulant medications. If taking these prescriptions, consult a healthcare practitioner before use. Natural color variation may occur.
Who should be cautious: People on statins, diuretics, or cardiac glycosides, and those with high blood calcium may need extra caution. Individuals using anticoagulant medications should avoid vitamin K without clinician guidance. If using medications that may interact with vitamin K or high-dose vitamin D, discuss with a healthcare provider before use.
Storage: Store in a cool, dry place after opening.
Many users report feeling improvements in bone strength and overall well-being after consistent use.
Capsules are easy to swallow with no noticeable aftertaste, fitting well into a once-daily routine.
Some users imply results appear with consistent use rather than immediately.
How It Works: Vitamins D3 and K2 have been extensively studied regarding their roles in calcium metabolism. Research indicates that a synergistic relationship exists between vitamin K2 and vitamin D3, especially in terms of bone strength and cardiovascular health. While vitamin D3 is recognized for its role in calcium absorption and metabolism, it is vitamin K2 that directs calcium to bones rather than joint spaces and arteries. This product is formulated with a clinically relevant dose of MK-7, a unique, soy-free form of vitamin K2 that has been shown to promote healthy vascular structures.
Take 1 capsule daily with a fat-containing meal, or as directed by your healthcare practitioner.
Vitamin D should be used cautiously by those taking cardiac glycosides and anyone with hypercalcemia. Vitamin D supplements may interact with atorvastatin and thiazide diuretics. Vitamin K is contraindicated with warfarin or other anti-coagulant medications. If you are taking any of these prescription medications, consult your healthcare practitioner before using this product.
Natural color variation may occur in this product.
