K2-D3 with Astaxanthin

K2-D3 with Astaxanthin, by Douglas Laboratories, supplies a significant amount of biologically active vitamin K2 in the form of menaquinone-7 (MK-7) with Vitamin D-3 for cardiovascular and bone health.

The addition of Astaxanthin, a powerful antioxidant, helps to further support healthy oxidative stress biomarkers to the vascular and systemic systems.

Douglas Labs’ Vitamin K2 as menaquinone-7 is soy-free and derived from geraniol and farnesol. Geraniol is the primary part of rose oil, palmarosa oil, and citronella oil. Farnesol is present in many essential oils such as citronella, lemon grass, rose, and musk.

This nature-identical form of menaquinone-7 has been extensively tested for molecular identity and bioequivalence when compared to menaquinone-7 from fermented soybeans (natto). It is the all-trans form, thus providing a pure, biologically active form.


K2-D3 with Astaxanthin is indicated for individuals desiring a high dose of vitamin K and vitamin D for blood vessel or bone health, with the added systemic health benefits of astaxanthin.
