Osteo-MK4 K2+D3 60c by NBI – Bone Health Support with Vitamin K2 and D3
Osteo-MK4® K2+D3 capsules by NBI combine the MK4 form of vitamin K2 with vitamin D3 for bone health support, without added calcium. This 60-capsule formula pairs two nutrients involved in normal bone maintenance while leaving calcium intake to food or a separately selected supplement.
Each capsule supplies 22,500 mcg of vitamin K as MK4 and 25 mcg (1000 IU) of vitamin D as cholecalciferol. The distinction matters when comparing vitamin K2 and D3 supplements: this formula uses MK4, not MK7, and its vitamin K amount deserves careful review alongside your medications and existing supplements.
Key Osteo-MK4 K2+D3 60c Benefits
- Supports normal bone maintenance with vitamin K2 and vitamin D3, nutrients that contribute to different aspects of skeletal nutrition.
- Helps support calcium absorption through vitamin D3, enabling the body to use calcium obtained from foods and other dietary sources.
- Provides vitamin K for activation of bone proteins involved in bone mineralization and normal bone metabolism.
How Osteo-MK4 K2+D3 60c Works
Bone is living tissue, continually maintained through the coordinated activity of cells, proteins, and minerals. Vitamin D3 is converted by the body into active vitamin D, which helps intestinal cells absorb calcium. Vitamin K supports a separate protein-activation process, including activation of osteocalcin, a protein made by bone-forming cells.
These are complementary nutritional roles, not interchangeable jobs. Calcium-free bone support supplies vitamin cofactors rather than the calcium mineral itself. Adequate calcium intake remains important; this formula is not a substitute for calcium-containing foods or an individualized plan for meeting mineral needs.
Key Functional Ingredients Include:
- Vitamin K: Supplied as K2, MK4, menaquinone-4, it helps activate vitamin K-dependent proteins, including osteocalcin. This activation enables those proteins to bind calcium as part of normal bone metabolism. Its role in blood clotting also explains why anticoagulant medication use is an important restriction for this formula.
- Vitamin D: Supplied as cholecalciferol, or D3, it helps regulate the absorption of calcium from the intestine after conversion to its active form. Making dietary calcium available supports normal bone mineralization. The vitamin D in this capsule complements, but does not provide, the calcium needed for bone structure.
Osteo-MK4 K2+D3 60c Is Formulated For
- Adults considering MK4 and D3 as part of an individualized bone-nutrition plan.
- People seeking these vitamins without added calcium, after reviewing their food intake and other supplements.
- Those whose healthcare professional has reviewed the vitamin K amount and medication restrictions.

Storage: Keep tightly closed in a dry place; do not expose to excessive heat.
Additional precautions: Review this high-amount MK4 formula with your healthcare professional before use, especially during pregnancy or breastfeeding or if you have a medical condition. Count vitamin D from all foods and supplements; excessive vitamin D can raise blood calcium and cause nausea, vomiting, weakness, thirst, frequent urination, and kidney problems. Thiazide diuretics can increase the risk of high blood calcium with vitamin D. Orlistat can reduce absorption of vitamins D and K; bile acid sequestrants can reduce vitamin K absorption. Prolonged antibiotics can affect vitamin K status, corticosteroids can lower vitamin D levels, and high-dose vitamin D may affect some statins. Have your prescriber or pharmacist review these combinations before adding this product.
Frequently Asked Questions About Osteo-MK4 K2+D3 60c
What are the benefits of Osteo-MK4 K2+D3 60c?
Osteo-MK4 K2+D3 60c combines vitamin K2 as MK4 with vitamin D3 to support normal bone nutrition. Vitamin D helps your body absorb dietary calcium, while vitamin K helps activate proteins involved in bone metabolism. Each capsule supplies 22,500 mcg of vitamin K and 25 mcg (1000 IU) of vitamin D. Because this NBI formula contains no added calcium, it lets you address these vitamin needs separately from your calcium intake.
Who should take Osteo-MK4 K2+D3 60c?
This formula is intended for adults considering MK4 and D3 within a personalized bone-nutrition plan, particularly when added calcium is not wanted in the same supplement. It is not interchangeable with a low-amount MK7 supplement. A healthcare professional should review its substantial MK4 amount, your other vitamin D products, and your medications. The label prohibits use with anticoagulant medication, including warfarin. Pregnancy, breastfeeding, or a medical condition requires individualized advice before use.
Are there any side effects of taking Osteo-MK4 K2+D3 60c?
The label states: Do not take this product if you are taking anticoagulant medication (eg, warfarin). Vitamin K interferes with warfarin. KEEP OUT OF THE REACH OF CHILDREN. Excessive total vitamin D can raise blood calcium, with nausea, weakness, thirst, frequent urination, and kidney problems. Ask your pharmacist about thiazide diuretics, orlistat, bile acid sequestrants, prolonged antibiotics, corticosteroids, and statins, as these can affect vitamin levels, absorption, or medication effects. Review pregnancy, breastfeeding, and medical conditions before starting this high-amount MK4 formula.
How does Osteo-MK4 K2+D3 60c support overall health?
Its main nutritional focus is the maintenance of healthy bones through two distinct vitamin functions. Vitamin D3 supports intestinal calcium absorption, while MK4 provides vitamin K for activation of proteins used in normal bone metabolism. These functions complement the calcium you obtain elsewhere; the capsules do not supply calcium themselves. NBI directs taking 1 capsule twice daily with meals or as directed by a healthcare professional, alongside an appropriate diet and individualized supplement review.
