Leviathan Nutrition Vitamin D3 K2 2 in 1 Formula | 360mcg Vitamin K2 (MK7) + 5000 IU Vitamin D3 Vegan Organic Extra Strength

What Makes MenaQ7 MK-7 the Superior Form of Vitamin K2?

Vitamin K2 comes in two main forms: MK-4 and MK-7. MK-7, derived from natto (fermented soy), has a longer half-life in the body, allowing for more consistent blood levels and sustained activation of vitamin K-dependent proteins. MenaQ7 is a clinically studied, patented form of MK-7 that has been shown to support bone and cardiovascular health in human trials.

Leviathan Nutrition uses MenaQ7 MK-7 because it is the only form of vitamin K2 with published clinical evidence demonstrating its benefits. Unlike cheaper MK-4 supplements that require multiple daily doses and absorb less efficiently, a single capsule of this formula provides 360 mcg of highly bioavailable MK-7. This activates matrix GLA protein, which helps maintain arterial flexibility, and osteocalcin, which binds calcium to the bone matrix.

Key Benefits of a D3 + K2 Combination

• Bone Health: Vitamin D3 enhances calcium absorption in the gut, while K2 activates proteins that incorporate calcium into bone tissue. Together, they help maintain bone density and support strong teeth.
• Heart Health: By directing calcium away from arteries and into bones, vitamin K2 may support arterial health and normal cardiovascular function. Clinical research on MenaQ7 suggests a role in maintaining arterial elasticity.
• Immune Function: Vitamin D3 is well-known for its role in immune cell regulation. Adequate levels help your body mount a healthy immune response.
• Joint Support: Healthy bones and proper calcium metabolism contribute to comfortable joint mobility and overall skeletal strength.
• Calcium Utilization: Without sufficient K2, calcium absorbed thanks to D3 may deposit in soft tissues. K2 ensures calcium goes where it’s needed most.

These combined benefits make this supplement a valuable addition to a daily wellness routine—especially for those at risk of deficiency or with higher needs.

Quality You Can Trust: Third-Party Testing and cGMP Standards

Leviathan Nutrition manufactures this supplement in a facility that adheres to strict cGMP (current Good Manufacturing Practices) and undergoes regular third-party audits. Each batch is tested by an independent laboratory for purity, composition, and potency. This means you get exactly what the label says—No fillers, No contaminants.

The formula is vegan, organic, and free from common allergens like gluten, soy, and dairy (though the source notes organic, we cannot claim non-GMO unless stated). The softgels are easy to swallow and designed for optimal absorption when taken with a meal containing fat.

Who May Benefit from This Supplement?

This formula is designed for adults seeking an extra-strength vitamin D and K2 combination. It may be particularly helpful for:

• Individuals with limited sun exposure, such as office workers or those living in northern climates.
• Vegans and vegetarians who may have lower dietary intake of vitamin D3 and K2 (note: the D3 here is vegan-sourced from lichen).
• Older adults, as aging reduces the skin’s ability to synthesize vitamin D and impairs calcium metabolism.
• People with darker skin, which naturally produces less vitamin D from sunlight.
• Those concerned about bone density or heart health who want a proactive approach.

As always, consult your healthcare provider before starting any new supplement, especially if you take blood thinners or have medical conditions.

How to Incorporate This Supplement Into Your Routine

Take one capsule daily with food, preferably a meal that contains healthy fats (like avocado, nuts, or olive oil) to enhance absorption of these fat-soluble vitamins. Consistency is key: regular intake helps maintain steady blood levels of both D3 and K2.

For most adults, 5,000 IU of vitamin D3 per serving is considered a higher maintenance dose or useful for correcting deficiency. The 360 mcg of MK-7 matches the amount used in successful clinical studies. If you are unsure about your vitamin D status, a simple blood test can guide your dosage.

Safety Considerations and Recommended Use

Vitamin D3 is fat-soluble and can accumulate in the body if taken in excessive amounts for prolonged periods. The tolerable upper intake level (UL) for adults is 4,000 IU per day from all sources, though higher doses under medical supervision are sometimes used. This product provides 5,000 IU per capsule, so we recommend not exceeding one capsule daily unless directed by your healthcare provider.

Vitamin K2 has No known toxicity, but it may interact with anticoagulant medications (e.g., warfarin). If you take blood thinners, consult your doctor before use. Pregnant or nursing women should also seek medical advice before supplementing with high-dose vitamin D3.

Store in a cool, dry place away from direct sunlight. Keep out of reach of children.

The Synergy of Vitamin D3 and Vitamin K2

Vitamin D3 and vitamin K2 are two fat-soluble nutrients that work together to support overall wellness. While vitamin D3 helps your body absorb calcium, vitamin K2 directs that calcium to your bones and teeth—and away from soft tissues like arteries. This dynamic duo is essential for maintaining strong bones, a healthy heart, and proper immune function. Leviathan Nutrition’s Vitamin D3 K2 2 in 1 Formula provides a potent combination of 5,000 IU of vegan vitamin D3 (cholecalciferol) and 360 mcg of vitamin K2 as Menaquinone-7 (MK-7), the most bioavailable form of K2.

Many people are deficient in vitamin D due to limited sun exposure, especially during winter or in northern latitudes. Pairing it with vitamin K2 ensures that the calcium you consume is used effectively. This supplement is ideal for those seeking an extra-strength, vegan, and organic option to support bone density, heart health, and immune resilience.
