insights Analysis
Vitamin K2 as MK-7 is widely recognized by nutritionists and scientific studies for its long half-life and superior bioavailability, enabling efficient transport of calcium to bones and away from soft tissues. The 100mcg dosage is an ideal daily intake for most adults seeking robust support for bone density and arterial elasticity. Nutricost is known for providing quality supplements at competitive prices, and the large 240-serving bottle (price: 1698, price per serving: 7) ensures long-term supply and excellent cost-effectiveness. Online reviews frequently praise its value and the noticeable benefits for bone health. The only minor drawback is the absence of D3, which many prefer in combination with K2 for full synergistic effects.
- Optimal 100mcg dosage of the superior MK-7 form of K2.
- Incredibly low price per serving (7) offering outstanding value for a high-quality K2 supplement.
- Large serving count (240) provides a long-term supply, enhancing cost-effectiveness.
- Excellent for targeted K2 supplementation for bone and cardiovascular health.
- Does not include Vitamin D3, which is often recommended alongside K2 for optimal synergistic benefits in calcium metabolism for bone and heart health.

bolt Effectiveness for goals
Vitamin K is essential for proper blood clotting and plays a significant role in bone metabolism. It helps the body produce proteins necessary for these vital bodily functions.
Vitamin K activates proteins such as osteocalcin, which are crucial for incorporating calcium into the bone matrix. This mechanism supports bone mineralization and helps maintain bone density.
Vitamin K1 (phylloquinone) is primarily effective for blood coagulation and is abundant in green leafy vegetables. Vitamin K2 (menaquinones) is more involved in bone and cardiovascular health, found in fermented foods and animal products, and has different bioavailabilities.
Emerging research suggests that Vitamin K, particularly K2, may help prevent arterial calcification by activating matrix Gla protein. This protein helps inhibit calcium deposition in soft tissues, supporting arterial flexibility.
Vitamin K works synergistically with calcium by helping to direct calcium to the bones and away from soft tissues like arteries. It activates proteins like osteocalcin for bone binding and matrix Gla protein to inhibit soft tissue calcification.
schedule Dosage, timing & forms
Recommended dosages for Vitamin K vary by age and form (K1 vs K2). For adults, the Adequate Intake (AI) for Vitamin K is 120 mcg per day for men and 90 mcg per day for women. Specific supplemental dosages may differ depending on individual needs and health goals.
Yes, dosages can differ between Vitamin K1 and K2 due to their varying potencies and half-lives. While K1 is measured in micrograms (mcg) for general intake, K2 (especially MK-7) may be effective at lower microgram doses due to its longer half-life. It's important to check the specific form and dosage on the supplement label.
Yes, Vitamin K is a fat-soluble vitamin, meaning it is best absorbed when taken with a meal containing some dietary fat. This helps facilitate its absorption into the body.
The two main forms of Vitamin K found in supplements are Vitamin K1 (phylloquinone) and Vitamin K2 (menaquinone). Vitamin K2 further has various subtypes, with MK-4 and MK-7 being the most common in supplements. Each form may have distinct roles and bioavailability.
There is no established Upper Limit (UL) for Vitamin K from food or supplements, as toxicity is rare. However, high doses of synthetic Vitamin K (menadione, K3) can be toxic, though this form is not typically found in supplements. Always adhere to recommended dosages and consult a healthcare provider if you have concerns.
health_and_safety Safety & interactions
Vitamin K plays a crucial role in blood clotting, which is the opposite effect of anticoagulant medications such as warfarin. Consuming inconsistent amounts of Vitamin K can alter warfarin's effectiveness, potentially making the blood thinner less effective or increasing bleeding risk. Individuals taking warfarin should maintain a consistent intake of Vitamin K and consult their healthcare provider.
Individuals taking anticoagulant medications like warfarin should consult their doctor before taking Vitamin K supplements due to potential interactions. People with certain liver conditions or those with a G6PD deficiency should also seek medical advice before supplementation. Always discuss new supplements with a healthcare provider.
Vitamin K supplements are generally considered safe for most healthy individuals when taken at recommended dosages. Side effects are uncommon but can include upset stomach, diarrhea, or allergic reactions in sensitive individuals. High doses of synthetic Vitamin K (menadione, K3) can be toxic, but this form is rarely used in supplements.
Vitamin K is essential during pregnancy and breastfeeding, and adequate intake is important for both mother and child. However, supplementation during these periods should only be undertaken under the guidance of a healthcare professional. High doses are generally not recommended without specific medical advice.
There is currently no established Tolerable Upper Intake Level (UL) for Vitamin K from food or supplements due to its low potential for toxicity. However, excessive intake, especially of synthetic forms, could potentially have adverse effects. It is always best to adhere to recommended dosages on supplement labels or as advised by a healthcare professional.
