Source Naturals Vitamina K2 + D3 Complejo para Huesos y Corazón - 400 UI Vitamina D3 y 100 mcg Vitamina K2 (MK-7) con Calcio - 60 Comprimidos

What is the D3 and K2 vitamin combination?

Vitamin D3 (cholecalciferol) and vitamin K2 (menaquinone) are two fat-soluble nutrients that work synergistically in the body. Vitamin D3 contributes to the normal absorption and utilization of calcium and phosphorus, while vitamin K2 contributes to the maintenance of normal bones and normal blood coagulation. This synergy is key for a balanced bone metabolism and adequate cardiovascular health.

Source Naturals Vitamin K2 + D3 combines 400 IU of vitamin D3 with 100 mcg of vitamin K2 in its most bioavailable form, menaquinone-7 (MK-7), also known as NattoMK-7. This form of K2 remains active in the body up to 12 times longer than other variants, allowing for sustained action and more convenient dosing.

Health Benefits

The health claims listed below have been evaluated and authorized by the European Food Safety Authority (EFSA). Vitamin D contributes to:

• Normal absorption and utilization of calcium and phosphorus.
• Maintenance of normal blood calcium levels.
• Maintenance of normal bones.
• Normal functioning of the immune system.

Likewise, vitamin K contributes to:

• Normal blood coagulation.
• Maintenance of normal bones.

These benefits reflect the essential role of both vitamins in human physiology. By combining D3 and K2, an optimal environment for bone mineralization and the maintenance of vascular health is promoted.

What makes this combination unique?

The choice of the MK-7 form of vitamin K2 makes the difference. Unlike MK-4, MK-7 has a longer half-life, providing stable plasma levels with a single daily dose. This form is obtained from natto (fermented soybeans), a traditional Japanese food. Additionally, vitamin D3 is presented in a moderate dose of 400 IU, suitable for daily maintenance in adults with normal sun exposure.

The product is formulated without yeast, dairy, egg, gluten or wheat, and contains no preservatives, artificial colors or flavors. It is a clean and safe option for people with food sensitivities.

Recommended dosage

The suggested dose is 1 tablet daily, preferably with a meal. Because vitamins D and K are fat-soluble, taking them with foods containing some fat (such as breakfast or dinner) can improve their absorption. Do not exceed the recommended daily dose. Each container holds 60 tablets, enough for two months of use.
