    Featured Ingredients

    Vitamin D3 – Vitamin D is an essential fat-soluble vitamin that acts as a key regulatory hormone for calcium and bone metabolism. Vitamin D plays a key role in many other body functions, including modulation of cell growth, neuromuscular and immune function, and regulatory support.

    Vitamin K2 – Vitamin K is needed to activate osteocalcin, which functions to take calcium out of the vessels and deposit it into the bones. Vitamin K2 is more bioactive and more effective than vitamin K1 and helps to distribute and utilize calcium properly throughout the body.

    Astaxanthin – This powerful carotenoid has become increasingly popular due to its numerous health benefits. Astaxanthin is a potent antioxidant and free radical scavenger, even more potent than lutein and zeaxanthin in certain systems. It is commonly used to reduce inflammation, improve cardiovascular health, and support anti-aging benefits.

    Q. Why is Astaxanthin Beneficial?

    A. Studies suggest that astaxanthin supports healthy oxidative stress biomarkers in LDL, cholesterol, NOS, and TNF-alpha. Astaxanthin helps to protect against lipid peroxidation and may improve vascular elastin and reduce arterial wall thickness by modulating the oxidative condition. It also helps to support eye and brain health against aging.

    Q. Why is Astaxanthin Combined with Vitamins D and K?

    A. K2-D3 supplies a significant amount of biologically active vitamin K2 with Vitamin D-3 for comprehensive 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.

    Q. How Should I Take K2-D3 with Astaxanthin for Best Results?

    A. Because Astaxanthin, vitamin D, and vitamin K are all fat-soluble vitamins, it is best to consume Astaxanthin with a fat-containing meal. This can include a handful of nuts, a salad with olive oil dressing, or a filet of fish. For best results, take once per day, first thing in the morning with a meal.

    Q. Why is Douglas Laboratories a Good Source of Astaxanthin?

    A. Douglas Laboratories uses a supercritical CO2 extract of the whole plant from Haematococcus pluvialis, the most plentiful source of astaxanthin available. It is manufactured in the USA in a GMP certified facility and contains no wheat, yeast, soy, preservatives, or genetically modified organisms.
