Health Benefits of Full Spectrum Vitamin K

Discover Allergy Research Group — Full Spectrum Vitamin K combines three active forms of vitamin K with vitamins A, C, and D3 to support your bones and circulatory system. This blend promotes healthy calcium metabolism and helps maintain arterial flexibility. Each form contributes uniquely: K1 supports normal blood clotting, MK-4 aids cellular health, and MK-7 provides sustained activity for daily calcium management.

  • Bone Metabolism: Vitamin K activates osteocalcin, a protein that binds calcium to the bone matrix, helping maintain bone density and strength.
  • Circulatory Function: It assists in regulating calcium within blood vessels, supporting arterial flexibility and normal blood flow.
  • Synergistic Nutrient Support: Vitamins A, C, and D3 work alongside vitamin K to support tissue maintenance, immune function, and antioxidant protection.

This product may not be suitable for everyone. Always read and follow the label. Keep out of reach of children. Consult a health-care practitioner if symptoms persist.

What Is Full Spectrum Vitamin K?

Full Spectrum Vitamin K from Allergy Research Group delivers three biologically active vitamin K forms: phylloquinone (K1), menaquinone-4 (MK-4), and menaquinone-7 (MK-7). Unlike single-form supplements, this complete spectrum ensures both short-acting K1 and longer-lasting MK-7 are provided alongside MK-4, which plays a unique role in tissue health. Each softgel also contains vitamins A, C, and D3 to enhance absorption and utilisation.

Vitamin K1 vs. MK-4 vs. MK-7: Understanding the Differences

Vitamin K is a family of compounds with distinct roles. K1 (phylloquinone) is mainly involved in blood clotting and has a short half-life. MK-4 (menaquinone-4) supports bone and vascular health, while MK-7 (menaquinone-7) from bacterial fermentation remains active longer, offering sustained calcium metabolism support. Combining all three provides a more complete approach than products with only K1 or K2.

Why Our Blend Includes Vitamins A, C, and D3

Vitamin K works best with other fat-soluble vitamins. D3 promotes calcium absorption, A supports cell differentiation and tissue health, and C acts as an antioxidant and is involved in collagen synthesis for bone and vascular integrity. This comprehensive blend ensures your body has the cofactors to use vitamin K efficiently. The softgels are free from common allergens like gluten, dairy, corn, nuts, and shellfish.

How to Use Full Spectrum Vitamin K

Take one softgel daily with a meal containing fat for optimal absorption. Each bottle provides 90 softgels – a three-month supply. The balanced dose of each vitamin K form supports optimal uptake. Always consult a health-care professional before starting any new supplement, especially if you are on blood-thinning medication or have a medical condition.

Potential Side Effects and Interactions

Full Spectrum Vitamin K is generally well tolerated when taken as directed. However, if you are on anticoagulant therapy (e.g., warfarin), consult your physician before use, as vitamin K can interfere with these medications. No serious side effects are expected, but mild digestive upset may occur. Vitamin K toxicity is rare due to efficient metabolism. If you experience any adverse reactions, discontinue use and seek medical advice.
