Vitamin D3 K2 5000 IU – 90 Vegetarian Capsules, High-strength D3 with K2 Supplement, Formula for Bone and Immune Health (Pack of 3)

Key Health Benefits

Bone Health Support

Vitamin D3 contributes to normal calcium absorption and utilisation, helping to maintain strong bones.* Vitamin K2 supports the incorporation of calcium into the bone matrix, contributing to the maintenance of normal bone density.* Together, they provide a solid foundation for skeletal strength.

Immune Function

Vitamin D3 is well-recognized for its role in supporting the normal function of the immune system.* By helping to maintain healthy vitamin D levels, this supplement contributes to overall immune defence.

Heart Health

Vitamin K2 helps activate matrix GLA protein (MGP), a protein that helps keep calcium from accumulating in arterial walls, which may support cardiovascular flexibility.*

Why Vitamin D3 and K2 Are Better Together

The combination of vitamin D3 and vitamin K2 is popular amongst those looking to optimise calcium metabolism. While vitamin D3 enhances calcium absorption from the digestive tract, vitamin K2 ensures that calcium is deposited in the bones and teeth rather than in soft tissues like arteries. This complementary action makes the duo a preferred choice for those aiming to support bone and cardiovascular health. Each capsule delivers 125 mcg (5,000 IU) of vitamin D3 as cholecalciferol and 90 mcg of vitamin K2 as menaquinone-7 (MK-7), the form valued for its longer half-life and sustained activity in the body.

The synergy between these two fat-soluble vitamins is grounded in their roles in calcium regulation. Vitamin D3 promotes the production of calcium-binding proteins in the intestinal lining, enhancing calcium uptake. Vitamin K2, in turn, activates osteocalcin, which binds calcium to the bone matrix, and matrix GLA protein (MGP), which may help prevent calcium deposition in blood vessels. By supporting these pathways, the combination helps maintain proper calcium distribution, which is particularly important for individuals seeking to optimise bone density and arterial flexibility.

What to Look For in a D3 + K2 Supplement

When selecting a vitamin D3 and K2 supplement, consider the dosage, form of K2, and purity. This supplement provides 5,000 IU of vitamin D3 and 90 mcg of vitamin K2 as MK-7, a ratio that aligns with common recommendations for daily maintenance. MK-7 is preferred over MK-4 due to its longer half-life, allowing for once-daily dosage. The capsules are vegetarian-friendly and free from gluten, dairy, soya, peanuts, artificial colours, flavours, preservatives, and high-fructose corn syrup. Each bottle contains 90 capsules, providing a three-month supply when taken as directed (one capsule per day).

Recommended Dosage

The suggested uses is one capsule per day with a meal, as both vitamins are fat-soluble and absorption is enhanced with dietary fats. Each capsule provides 5,000 IU of vitamin D3 and 90 mcg of vitamin K2. Do not exceed the recommended dose unless advised by a health care professional. Always consult your doctor before uses, especially if you are pregnant, nursing, or have a medical condition.

Frequently Asked Questions

Can I take vitamin D3 and K2 together?

Yes, taking them together is generally safe and recommended for their synergistic effects on calcium metabolism.

When is the best time to take this supplement?

Since both vitamins are fat-soluble, taking them with a meal containing healthy fats can enhance absorption.

Are there any interactions with medicines?

If you are taking anticoagulant medications (e.g., warfarin), speak to your doctor or pharmacist before using vitamin K2 supplements, as K2 can interfere with therapy.

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

MK-7 is derived from natto (fermented soya) and has a longer half-life in the body, making once-daily dosage convenient. MK-4 has a shorter half-life and may require multiple doses per day. This product uses MK-7 for sustained activity.
