Horbäach Vitamin D3 K2 5000 IU + 100mcg MK-7 Complex, 180 Softgels

How Do D3 and K2 Work Together?

The synergy between D3 and K2 is rooted in their complementary roles. Vitamin D3 (cholecalciferol) increases the production of calcium-binding proteins in the gut, enhancing calcium absorption. Vitamin K2 (specifically menaquinone-7, or MK-7) then activates two proteins: osteocalcin, which helps bind calcium to the bone matrix, and matrix GLA protein (MGP), which may help prevent calcium from depositing in blood vessel walls. This partnership supports normal calcium balance—mineralisation of bones while maintaining arterial flexibility.* The MK-7 form of K2 is particularly effective because it stays active in the bloodstream longer than MK-4, providing sustained support throughout the day.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and vitamin K2 work as a team to support your body’s calcium metabolism. While vitamin D3 helps your intestines absorb calcium from food, vitamin K2 directs that calcium to the right places—your bones and teeth—and away from soft tissues like arteries. Taking them together ensures you get the full benefit of each nutrient. Many people take vitamin D3 on its own, but without adequate K2, calcium may not be properly deposited. This combination is especially helpful for those looking to support bone density, cardiovascular health, and immune function.*

Key Health Benefits

Bone Health: By improving calcium absorption and directing it to bones, D3 and K2 help maintain strong, dense bones as you age. This is especially important for postmenopausal women and older adults.*

Heart Health: Vitamin K2 helps keep calcium out of arteries, which supports normal arterial elasticity and cardiovascular function.*

Immune Support: Vitamin D3 is known for its role in healthy immune cell function, helping your body respond to seasonal challenges.*

Dental Health: Proper calcium utilisation also benefits teeth, as K2 helps direct calcium into tooth dentin, supporting strong enamel.*

Each soft gel capsule of Horbäach’s formula provides 125 mcg (5,000 IU) of vitamin D3 and 100 mcg of vitamin K2 (MK-7), a balanced ratio that aligns with current research on optimal daily intake.

What to Look For in a D3 + K2 Supplement

• Form of K2: Look for MK-7, the longer-acting form derived from natto (fermented soya) or synthetic sources. This formula uses MK-7 for sustained benefits.
• Dosage Ratio: A common effective ratio is 5,000 IU D3 to 100 mcg K2 (MK-7). Horbäach provides exactly this.
• Purity: Choose a supplement that is non-GMO, gluten-free, and free of artificial additives. Horbäach’s softgels are naturally free of gluten, wheat, yeast, milk, lactose, artificial flavours, and sweeteners.
• Third-Party Testing: The brand emphasises laboratory-tested ingredients and superior quality, ensuring potency and purity.

Recommended Dosage and Usage

As a dietary supplement, take one soft gel capsule daily with a meal that contains some fat, since vitamins D and K are fat-soluble. This enhances absorption. Do not exceed the recommended dose. Store in a cool, dry place. If you are pregnant, nursing, taking medication (especially blood thinners like warfarin), or have a medical condition, consult your health care provider before uses.

Frequently Asked Questions

Can I take vitamin D3 and K2 separately? Yes, but taking them together ensures optimal calcium utilisation. Many users prefer the convenience of a combined supplement.

Is this supplement safe for long-term uses? When taken as directed, D3 and K2 are generally safe for long-term uses. However, monitor your vitamin D levels periodically, especially if you take more than 4,000 IU daily.

Does this product contain soya? While K2 MK-7 is often sourced from natto (soya), Horbäach does not list soya as an ingredient and uses non-GMO ingredients. If you have severe soya allergy, contact the manufacturer.
