Natural Factors Vitamin D3 & K2 1000 IU/120 mcg - 60 Soft Gel Capsules

Key Health Benefits of Vitamin D3 and K2

Vitamin D3 and K2 combine to support your body's natural calcium handling, ensuring this vital mineral is absorbed from your diet and directed to where it matters most – your bones and teeth. With 1000 IU of cholecalciferol (vitamin D3) and 120 mcg of menaquinone (vitamin K2 as MK-7) per soft gel capsule, Natural Factors provides a well-studied dose for general maintenance. This combination is particularly beneficial for those concerned with maintaining bone density as they age. This dynamic duo not only contributes to normal bone health but also supports your immune system and muscle function, thanks to vitamin D3, while vitamin K2 promotes normal blood clotting. Together, they help maintain a healthy balance of calcium in your body.

How D3 and K2 Work in Harmony

Vitamin D3 increases the absorption of calcium from the gut by promoting the expression of calcium-binding proteins. On the other hand, vitamin K2 activates two key proteins: osteocalcin, which anchors calcium to the bone matrix, and matrix GLA protein (MGP), which helps prevent calcium from depositing in soft tissues like arteries. Without enough K2, the calcium pulled in by D3 may not be properly utilised. The MK-7 form of K2 used in this supplement has a longer half-life than MK-4, ensuring sustained activation of these proteins throughout the day. The MK-7 form is derived from fermented chickpeas, offering a natural and effective source of vitamin K2. This synergy helps maintain normal calcium balance, supporting bone density and vascular flexibility. The result is a coordinated system that directs calcium to your skeleton and teeth while keeping it away from where it could cause harm.

Why Choose a Combined D3 & K2 Supplement?

Taking vitamin D3 alone can increase calcium absorption, but without K2, some of that calcium may end up in the wrong places, such as artery walls. By taking them together, you support the body's natural calcium trafficking: D3 pulls calcium into the bloodstream, and K2 activates proteins that guide it to the bones and teeth while discouraging deposition in soft tissues. This synergistic approach is why many health-conscious individuals prefer a combined D3+K2 supplement over D3 alone. By taking them together, you ensure that the calcium you absorb is used where it is needed most, reducing the risk of unwanted calcium deposits. Natural Factors Vitamin D3 & K2 provides a convenient, balanced dose in one soft gel capsule, simplifying your daily routine and ensuring you get the benefits of both nutrients in the right ratio.

What to Look For in a Quality D3+K2 Supplement

Not all D3+K2 supplements are created equal. The dosage ratio matters: 1000 IU of D3 paired with 120 mcg of K2 (as MK-7) is a well-studied combination for general maintenance. The form of K2 is crucial – MK-7 offers superior bioavailability and a longer active life compared to MK-4. Natural Factors use highly bioavailable forms of both nutrients in a soft gel capsule format for optimal absorption. Additionally, this supplement is third-party tested for purity and potency, verified non-GM, and screened for over 800 contaminants using mass spectrometry. Natural Factors also ensures their products are manufactured in a GMP-certified facility, and each batch is tested for purity and potency. Look for similar quality indicators when choosing your supplement, and always check for transparent labelling of ingredient sources and dosage.

Recommended Dosage and Usage

Take one soft gel capsule daily with a meal, or as directed by your health care professional. Each soft gel capsule provides 1000 IU of vitamin D3 and 120 mcg of vitamin K2 (as MK-7). Since these are fat-soluble nutrients, taking them with a meal that contains healthy fats enhances absorption. Many people take their soft gel capsule with breakfast or lunch. If you have specific health concerns or are on medication, consult your doctor before use. For best results, maintain consistent daily intake. Adequate magnesium levels are also important for vitamin D activation. This product is suitable for adults looking to support bone, cardiovascular, and immune health.
