Leviathan Nutrition Vitamin D3 K2 2-in-1 Formula | 360 mcg Vitamin K2 (MK-7) + 5000 IU Vitamin D3 Vegan Organic Extra Strength

Key Benefits of a D3 K2 Supplement

• Bone Health: Vitamin D3 contributes to normal absorption and utilisation of calcium and phosphorus, while vitamin K2 contributes to maintenance of normal bones. Together, they support bone density and strong teeth.
• Heart Health: Vitamin K2 contributes to normal blood clotting, an important aspect of heart health. By supporting proper calcium utilisation, it helps maintain healthy blood vessels.
• Immune Function: Vitamin D3 contributes to the normal function of the immune system, helping your body mount a healthy defence.

Who May Benefit from This Food Supplement?

This formula is designed for adults who may have increased needs or limited dietary sources. 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 ageing reduces the skin’s ability to synthesise 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 health care practitioner before starting any new supplement, especially if you take anticoagulants or have medical conditions.

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

Vitamin K2 comes in two main forms: MK-4 and MK-7. MK-7, derived from natto (fermented soya), 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 with published evidence supporting bone and cardiovascular health in human trials.

Leviathan Nutrition uses MenaQ7 MK-7 because it offers superior bioavailability. Unlike cheaper MK-4 supplements that require multiple daily doses, a single capsule of this formula provides 360 mcg of highly bio-available MK-7, activating matrix GLA protein and osteocalcin for optimal calcium binding.

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 from the gut, vitamin K2 directs that calcium to your bones and teeth—and away from soft tissues. This combination ensures that calcium is used effectively for bone maintenance and immune function.

Many people are deficient in vitamin D due to limited sun exposure, especially during winter. Pairing it with vitamin K2 optimises the benefits of both nutrients. This food supplement is ideal for those seeking an extra-strength, vegan, and organic option to support bone density, normal blood clotting, and immune resilience.

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

Leviathan Nutrition manufactures this food supplement in a facility that adheres to strict Good Manufacturing Practice (GMP) and undergoes regular 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, soya, and dairy. The soft gel capsule capsules are easy to swallow and designed for optimal absorption when taken with a meal containing fat.

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 Uses

Vitamin D3 is fat-soluble and can accumulate in the body if taken in excessive amounts for prolonged periods. The tolerable upper intake level for adults is 4,000 IU per day from all sources, whilst 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 health care practitioner.

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 uses. 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.
