Designs for Health D-Evail 10K - 10,000 IU Vitamin D3 with K1, K2 (MK-4) & GG - 60 Softgels

Understanding the Synergy: How D3 and K2 Work Together

Vitamin D3 (cholecalciferol) stimulates the production of calcium-binding proteins in the intestines, which increases calcium absorption. However, without adequate vitamin K2, the newly absorbed calcium may not be properly utilised. Vitamin K2 activates matrix GLA protein (MGP) and osteocalcin—two proteins that help direct calcium to bones and teeth and help prevent calcium deposition in blood vessels. Vitamin K1 also plays a role in supporting normal blood clotting. The addition of geranylgeraniol (GG) in this formula supports the body's ability to produce active forms of vitamin K2, enhancing its effectiveness.

The D-Evail Advantage: Enhanced Absorption

The Evail technology sets this product apart by combining quillaja extract (a natural source of saponins) with MCT oil. This combination helps emulsify the fat-soluble vitamins, improving their absorption and bioavailability. This means you get more from each soft gel capsule, making the high potency even more effective.

What to Look For in a D3 + K2 Supplement

When choosing a vitamin D3 and K2 supplement, consider the dosage and form. D-Evail 10K provides 10,000 IU of vitamin D3—a potent dose for those with higher needs. The vitamin K2 is delivered as MK-4 (menaquinone-4), a form that is rapidly utilised by the body. This product also includes vitamin K1 and GG, which are not commonly found in standard D3/K2 formulae. The softgels are made without GMOs, gluten, dairy, or soya, and the brand is trusted by functional medicine professionals.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and vitamin K2 work as a team to support your body's calcium management. Vitamin D3 helps increase calcium absorption from the gut, while vitamin K2 helps direct that calcium to the bones and teeth where it is needed, and away from soft tissues like arteries. This synergistic relationship is why many experts recommend taking them together. The D-Evail 10K formula goes a step further by also including vitamin K1 and geranylgeraniol (GG) to further support this process.
