K2-D3 with Astaxanthin 30c by Douglas Laboratories – Bone Health Vitamin K2 and D3 Supplement
K2-D3 with Astaxanthin capsules by Douglas Laboratories combine soy-free MK-7 vitamin K2, vitamin D3 and astaxanthin in a vegetarian capsule. This formula pairs nutrients involved in calcium use with an algae-derived antioxidant, rather than providing vitamins D and K alone.
Key K2-D3 with Astaxanthin 30c Benefits
- Supports bone health by supplying vitamins D3 and K2, nutrients with complementary roles in maintaining normal bone tissue.
- Helps the body absorb dietary calcium and use it in the ongoing process of normal bone mineralization.
- Provides antioxidant support through astaxanthin, a carotenoid that helps protect cell membrane lipids from oxidative stress.
How K2-D3 with Astaxanthin 30c Works
Bone maintenance depends on more than calcium intake alone. Vitamin D helps regulate calcium absorption in the intestine, while vitamin K activates proteins involved in bone metabolism. Astaxanthin plays a separate role as an antioxidant associated with cell membranes, where fats can be vulnerable to oxidation.
Key Functional Ingredients Include:
- Vitamin K-2: Helps activate osteocalcin, a protein involved in normal bone metabolism. This vitamin K2 is supplied as menaquinone-7 (MK-7), supporting the vitamin K-dependent processes that help maintain bone tissue. Vitamin K can interfere with warfarin and requires medical guidance when used with blood thinners.
- Vitamin D-3: Supports absorption of calcium from food. The body converts cholecalciferol into active vitamin D, which helps intestinal cells move calcium into the bloodstream. This makes dietary calcium available for normal bone mineralization and complements vitamin K2’s role in bone maintenance.
- Astaxanthin: Contributes antioxidant activity in cell membranes. This fat-soluble carotenoid helps neutralize reactive molecules that can oxidize membrane lipids, adding a different type of nutritional support alongside vitamins K2 and D3. The formula sources astaxanthin from Haematococcus pluvialis.
K2-D3 with Astaxanthin 30c Is Formulated For
- Adults seeking combined vitamins K2 and D3 for normal bone maintenance.
- Adults who want astaxanthin alongside their vitamin D and K supplement.
- Adults who prefer vegetarian capsules and whose practitioner has reviewed their medications and vitamin D intake.
