K2-D3 with Astaxanthin provides biologically active vitamin K2 as menaquinone-7 (MK-7), vitamin D3 as cholecalciferol, and astaxanthin from a supercritical CO2 extract of Haematococcus pluvialis (entire plant). The vitamin K2 in this formula is soy-free and derived from geraniol and farnesol — nature-identical menaquinone-7 that has been tested for molecular identity and supplied in the all-trans form for full biological activity.

This formula supports cardiovascular and bone health by providing vitamin K2 (MK-7) and vitamin D3. Astaxanthin helps maintain healthy oxidative stress biomarkers in vascular and systemic tissues. The combination is suited for individuals seeking support for blood vessel health, bone health, and systemic antioxidant function.

Suggested Use: Adults take 1 capsule daily with a meal or immediately following a meal, or as directed by your healthcare professional.

Free From: This product's vitamin K2 (menaquinone-7) is soy-free.

Caution: Keep out of reach of children. If you are pregnant or nursing, or taking medications (especially anticoagulant/blood-thinning medications), consult your healthcare professional before use.

K2-D3 with Astaxanthin

Short summary

K2-D3 with Astaxanthin provides vitamin K2 as soy-free, all-trans menaquinone-7 (MK-7), vitamin D3 as cholecalciferol, and astaxanthin from a supercritical CO2 extract of Haematococcus pluvialis. Together, these three ingredients support cardiovascular health, bone health, and healthy oxidative stress biomarkers in vascular and systemic tissues. One vegetarian capsule daily supplies 180 mcg MK-7, 2,500 IU vitamin D3, and 2 mg astaxanthin.

What It Is

K2-D3 with Astaxanthin is a one-capsule-per-day vegetarian capsule formula containing vitamin K2 (as soy-free, all-trans menaquinone-7), vitamin D3 (as cholecalciferol), and astaxanthin (supercritical CO2 extract of Haematococcus pluvialis, entire plant). It provides 180 mcg MK-7, 2,500 IU vitamin D3, and 2 mg astaxanthin per serving in a 30-serving container.

How It Works

Vitamin K2 as menaquinone-7 supports cardiovascular health and helps maintain healthy vascular tissue, and promotes proper calcium distribution to support bone health. Vitamin D3 promotes healthy calcium absorption and supports bone mineral density. Astaxanthin, derived from Haematococcus pluvialis (entire plant) via supercritical CO2 extraction, helps maintain healthy oxidative stress biomarkers in vascular and systemic tissues.

When To Use It

Intended for adults seeking support for cardiovascular health, bone health, and healthy oxidative stress balance. Take 1 vegetarian capsule daily with a meal or immediately following a meal, or as directed by a healthcare professional. If pregnant, nursing, or taking medications — particularly anticoagulant or blood-thinning medications — consult a healthcare professional before use.

Suggested Use

Adults take 1 capsule daily with a meal or immediately following a meal, or as directed by your healthcare professional.

Practitioner Note

Vitamin K2 as menaquinone-7 may interact with anticoagulant medications, including warfarin; advise individuals taking such medications to consult their prescribing clinician before use. The menaquinone-7 in this formula is soy-free, derived from geraniol and farnesol, and supplied in the all-trans form — tested for molecular identity and bioequivalence to natto-derived MK-7. Each capsule provides 2,500 IU vitamin D3 and 180 mcg MK-7; monitor vitamin D status as clinically appropriate. Not for use during pregnancy or nursing without professional supervision.

Clinical Highlights

  • Vitamin K2 (MK-7), 180 mcg: Soy-free, all-trans menaquinone-7 derived from geraniol and farnesol; tested for molecular identity and bioequivalence to natto-derived MK-7; supports cardiovascular and bone health.
  • Vitamin D3 (cholecalciferol), 2,500 IU: 625% DV per capsule; promotes healthy calcium absorption and supports bone mineral density.
  • Astaxanthin, 2 mg: Supercritical CO2 extract of Haematococcus pluvialis (entire plant); helps maintain healthy oxidative stress biomarkers in vascular and systemic tissues.
  • Soy-Free K2: Vitamin K2 (menaquinone-7) is soy-free and nature-identical, supplied in the all-trans form for full biological activity.
  • Serving Format: 1 vegetarian capsule per day; 30 servings per container; other ingredients: hydroxypropyl methylcellulose (capsule), cellulose, vegetable stearate.
