Sports Research Vitamin D3 with K2 Softgels – Vegan D3 & K2 MK-7, 5000 IU, 120 Count

Understanding the Synergy: How D3 and K2 Work Together

Vitamin D3 (cholecalciferol) supports the production of calcium-binding proteins, which enhance calcium absorption in the intestines. Vitamin K2, specifically as menaquinone-7 (MK-7), helps activate osteocalcin and matrix GLA protein (MGP). Osteocalcin binds calcium to the bone matrix, while MGP helps prevent calcium from depositing in blood vessel walls.*

This complementary action means D3 and K2 don't just work side by side—they depend on each other for optimal calcium management. Research suggests that adequate levels of both nutrients support healthy bone remodelling and maintain arterial flexibility.*

Key Health Benefits of Vitamin D3 with K2

• Bone Support: Vitamin D contributes to normal absorption and utilisation of calcium and phosphorus, and vitamin K contributes to the maintenance of normal bones. Together they promote strong, healthy bones.*
• Immune Function: Vitamin D is recognized for its role in the normal function of the immune system. Pairing it with K2 provides additional support for overall immune health.*
• Cardiovascular Health: By directing calcium to bones and away from arteries, K2 helps maintain normal blood vessel flexibility and contributes to normal blood clotting.*
• Dental Health: Calcium directed to teeth supports enamel strength and dental integrity.*

With 5000 IU of vegan D3 and 100 mcg of MK-7 K2, this formula provides a potent dose to support these benefits in just one soft gel capsule per day.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and vitamin K2 form a powerful partnership for your body's calcium metabolism. While D3 helps your body absorb calcium from food, K2 directs that calcium to your bones and teeth where it belongs—instead of allowing it to accumulate in soft tissues like arteries. This synergy supports bone density, cardiovascular health, and immune function.*

Taking them together ensures you get the full benefit of each nutrient. Without enough K2, the calcium D3 helps absorb may end up in the wrong places. That's why a combined D3 + K2 supplement is a smart choice for anyone looking to optimise their wellness routine.

What to Look For in a D3 + K2 Supplement

Not all D3 and K2 supplements are created equal. Here's what makes this formula stand out:

• Plant-Based Sourcing: The D3 comes from lichen, not lanolin, and the K2 (MK-7) is derived from fermented chickpeas. This makes it suitable for vegans and those avoiding animal products.
• Optimal Dosage: 5000 IU (125 mcg) of D3 and 100 mcg of MK-7—a ratio that aligns with current research for supporting bone and heart health.*
• Absorption Enhancement: Coconut MCT oil is included to facilitate the absorption of these fat-soluble vitamins, ensuring your body can uses them effectively.
• Clean Certification: Vegan Certified, Non-GMO Project Verified, and free from gluten, soya, carrageenan, and artificial fillers. Each batch is third-party tested for purity and potency.

Recommended Dosage

For adults, the suggested serving is one soft gel capsule daily, preferably with a meal containing fat for optimal absorption. This formula provides 5000 IU of vitamin D3 and 100 mcg of vitamin K2 (as MK-7). Always consult your health care professional before starting any new supplement regimen, especially if you are taking medications such as blood thinners (e.g., warfarin) or have a medical condition.

Frequently Asked Questions

Is it safe to take 5000 IU of vitamin D3 daily?

For most adults, 5000 IU per day is within safe limits. However, individual needs vary based on age, sun exposure, and health status. It is best to consult your doctor to determine the right dosage for you.

What is the difference between MK-4 and MK-7 vitamin K2?

MK-7, used in this formula, has a longer half-life in the body compared to MK-4, allowing for more consistent blood levels with once-daily dosage. MK-7 is also better studied for bone and cardiovascular benefits.

Can I take this supplement with other medications?

If you are taking blood thinners, consult your health care professional before using vitamin K2 supplements, as K2 may interfere with anticoagulant therapy. Always check with a professional.
