Naturalis Vegan Vitamin D3+K2 from Algae | 5000 IU D3 with 120mcg MK7 | Vegan Society Certified | 60 Softgels

Key Health Benefits

• Bone Health: Vitamin D3 contributes to normal calcium absorption and the maintenance of normal bones. Vitamin K2 also contributes to normal bones.
• Immune Support: Vitamin D3 contributes to the normal function of the immune system.
• Dental Health: Vitamin D3 contributes to the maintenance of normal teeth.
• Heart Health: Vitamin K2 helps maintain normal blood clotting and supports arterial flexibility by directing calcium away from vessel walls.

These benefits are best achieved when D3 and K2 are taken together in appropriate ratios, as found in Naturalis Vegan D3+K2.

What to Look For in a D3 + K2 Supplement

Not all D3+K2 supplements are created equal. Here are key factors to consider:

• Source of D3: Most D3 is derived from lanolin (sheep's wool). Naturalis uses algae-sourced D3, making it 100% vegan and sustainably harvested from Nannochloropsis oceanica microalgae.
• Form of K2: Vitamin K2 comes in two forms: MK-4 (short half-life) and MK-7 (longer half-life). Naturalis uses natto-based MK-7, which remains active in the bloodstream longer, providing sustained support.
• Dosage Ratio: A common effective ratio is 5000 IU D3 to 120 mcg K2 (MK-7). This ensures adequate D3 for absorption without overwhelming the K2 pathway.
• Purity & Testing: Look for third-party testing, non-GMO, gluten-free, and vegan certifications. Naturalis is manufactured in a GMP certified facility in California and carries Vegan Society certification.
• Base Oil: Organic extra virgin olive oil aids absorption of fat-soluble vitamins and enhances bioavailability.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and K2 work synergistically to support your body's calcium metabolism. While vitamin D3 enhances calcium absorption from the gut, vitamin K2 guides that calcium to where it is needed most—your bones and teeth—and away from soft tissues like arteries. This partnership is essential for maintaining strong bones, healthy teeth, and cardiovascular wellness. Without adequate K2, calcium absorbed with D3 may not be properly utilised, potentially accumulating in arteries rather than bone.

Naturalis combines these two nutrients in a single, convenient soft gel capsule, ensuring you get the optimal ratio for maximum benefit. Each serving delivers 5000 IU of algae-based D3 and 120 mcg of natto-based MK-7, the most bio-available form of K2.

Understanding the Synergy: How D3 and K2 Work Together

To appreciate why this combination is so effective, it helps to understand the mechanisms at play. Vitamin D3 (cholecalciferol) supports the production of calcium-binding proteins in the intestinal lining, enhancing calcium absorption. Vitamin K2, specifically the MK-7 form, helps activate two key proteins: osteocalcin and matrix GLA protein (MGP).

Osteocalcin binds calcium to the bone matrix, helping maintain bone density and strength. MGP, on the other hand, helps prevent calcium deposition in blood vessels, supporting arterial flexibility and heart health. By taking D3 and K2 together, you ensure that the calcium you absorb is directed to bones and teeth rather than accumulating in soft tissues.

This synergy is particularly important for individuals on high-dose vitamin D supplementation, as it helps maintain healthy calcium balance throughout the body.
