  • Douglas Labs K2-D3 with Astaxanthin is an easy way to get 3 powerful supplements in 1 capsule.  It supports bone and cardiovascular health with a powerful combination of vitamins K2 and D3 and includes the antioxidant astaxanthin.
  • Douglas Labs K2-D3 supplies a significant amount of biologically active vitamin K2 in the form of menaquinone-7 (MK-7) (soy-free) 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.
  • Vitamin D is often called “the sunshine vitamin” but since most people do not get enough sunshine daily, supplementation is often necessary.  Vitamin D is critical to many processes in the body including calcium absorption, bone remodeling and cell growth.
  • Vitamin K plays a key role in taking the calcium out of the blood vessels and distributing it to the bones. Loading up on calcium is not effective without vitamin K to distribute it.
  • Astaxanthin is a naturally sourced powerful carotenoid that provides numerous health benefits.  It is most important to cardiovascular and immune health and systemic regulatory balance.

Available in 30ct vegetarian capsules.
