DRFOSTER Vitamin D3 & K2 Supplement – 5000 IU D3 + 100 mcg K2 (MK-7) with Vitamin E, Folic Acid & Methyl B12 – 120 Capsules

Understanding the Synergy: How D3 and K2 Work Together

Vitamin D3 (cholecalciferol) supports the production of calcium-binding proteins in the gut, helping the body absorb calcium from food. Vitamin K2 (menaquinone-7) activates two key proteins: osteocalcin, which anchors calcium into the bone matrix, and matrix GLA protein (MGP), which helps prevent calcium deposition in blood vessels. Together, D3 and K2 maintain healthy calcium balance: D3 brings calcium in, and K2 directs it to the right places. This synergy is especially important for older adults, individuals with limited sun exposure (common in Canadian winters), and those seeking proactive bone and heart support. Natural vitamin E in this formula may aid absorption and provide antioxidant protection.

Key Health Benefits

Bone Health: Vitamin D3 supports calcium absorption, while vitamin K2 helps incorporate calcium into bone tissue. Together, they help maintain strong, dense bones and may support healthy bone remodeling as part of a balanced diet.

Heart Health: By activating MGP, vitamin K2 helps keep calcium from accumulating in arterial walls, which may support arterial flexibility and overall cardiovascular wellness.

Immune Function: Vitamin D3 is known to help support normal immune function, helping the body maintain its natural defenses.

Energy and Vitality: This formula includes 400 mcg of folic acid and 50 mcg of methylcobalamin (active B12), which help support red blood cell formation and energy metabolism, promoting mental clarity and daily energy.*

Antioxidant Support: Natural vitamin E (d-alpha tocopherol) helps protect cells from oxidative stress, complementing the other nutrients for comprehensive wellness.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and vitamin K2 are a powerful duo for overall wellness. Vitamin D3 helps increase calcium absorption from the diet, while vitamin K2 directs that calcium to the bones and teeth where it is needed most, rather than allowing it to settle in soft tissues like arteries. This synergistic relationship supports bone density and cardiovascular health simultaneously. Many people take vitamin D3 alone, but without adequate K2, calcium may not be properly utilized. Combining them ensures your body gets the full benefits of both nutrients. The DRFOSTER formula provides high-potency D3 and K2 (as MK-7) along with complementary nutrients for enhanced support.

What to Look For in a D3 + K2 Supplement

When choosing a D3 and K2 supplement, consider the dosage, form of K2, and additional ingredients. Look for vitamin K2 as MK-7, which has a longer half-life and more sustained benefits than MK-4. This product delivers 125 mcg (5000 IU) of vitamin D3 and 100 mcg of MK-7, a well-studied ratio. The addition of vitamin E may enhance absorption of fat-soluble vitamins. Purity matters: opt for non-GMO, allergen-free, and third-party tested formulae. DRFOSTER uses veggie capsules and avoids artificial additives. Check for complementary B vitamins like folic acid and methyl B12, which support energy and cognitive function. Always consult your health care provider before starting a new supplement, especially if you are on blood thinners (due to K2’s interaction with warfarin).

As a dietary supplement, take one capsule daily with a meal. Each bottle contains 120 capsules, a four-month supply. Do not exceed the recommended dose. Keep out of reach of children. Store in a cool, dry place. If you are pregnant, nursing, or have a medical condition, consult your health-care professional before use. Always read the label and follow directions for use.
