Vitamin D3 4000 IU + Vitamin K2 (MK7) 100 mcg | 180 Tablets | EVO Nutrition

EVO Nutrition Vitamin D3 4000 IU with Vitamin K2 100 mcg comes as 180 tablets pairing the two fat-soluble vitamins that work together to steer calcium into bone and teeth and away from artery walls. The combination suits anyone who spends daylight hours indoors with little sun exposure, and anyone taking calcium who wants it deposited where it belongs. A 180 tablet bottle covers a long daily cycle at one tablet per day.

What are vitamin D3 and vitamin K2?

Vitamin D3, cholecalciferol, is a fat-soluble vitamin synthesised in the skin on exposure to ultraviolet light, and it behaves inside the body more like a hormone than a vitamin. Vitamin K2 is a family of compounds called menaquinones, and the form used in this tablet is MK-7, typically derived from fermented soy. Together they form a functional pair: the first opens the door to calcium absorption, the second decides where that calcium settles.

Benefits of vitamin D3 with K2 MK-7

• Bone density support: vitamin D3 raises intestinal calcium absorption, and vitamin K2 directs that calcium into bone tissue.
• Arterial health support: vitamin K2 activates a protein that limits calcium deposition in vessel walls.
• Immune support: vitamin D3 receptors are found on many immune cells, including T cells and macrophages.
• Dental health support: vitamin K2 takes part in maturing the proteins that depend on it within dentine and enamel.
• Muscle strength support: vitamin D3 is linked to muscle fibre function and postural stability.
• Mood and sleep support: vitamin D3 levels are linked to circadian rhythm and general wellbeing.
• Metabolic balance support: studies link vitamin K2 to cellular insulin sensitivity.

Active ingredients

• Vitamin D3 4000 IU: the cholecalciferol form, identical to what skin produces under sunlight, responsible for raising calcium and phosphorus absorption.
• Vitamin K2 100 mcg: the long-lived MK-7 form, which activates the proteins that place calcium in bone and keep it out of arteries.

How vitamin D3 and K2 work in the body

After absorption, vitamin D3 passes through two activation steps: first in the liver, where it becomes 25-hydroxyvitamin D, the form measured in blood tests, and then in the kidney, where it becomes active calcitriol, which binds the vitamin D receptor and triggers production of calcium transport proteins in the intestinal wall. Vitamin K2 acts as a cofactor for gamma-glutamyl carboxylase, the enzyme that carboxylates osteocalcin in bone and matrix Gla protein in the artery wall, enabling the first to fix calcium in bone and the second to prevent its deposition in vessels.

What sets this formula apart

EVO Nutrition uses the MK-7 form of vitamin K2 rather than MK-4, and the difference is substantial. The longer side chain of MK-7 gives it a half-life measured in days, so it stays in circulation and a single daily intake is enough, while MK-4 is cleared within hours and needs repeated dosing through the day. Combining vitamin D3 and vitamin K2 in one tablet also addresses the best known gap in taking vitamin D alone, which raises calcium absorption without anything to direct it into bone. The 180 tablet bottle covers a long uninterrupted daily cycle.

Who is this product for?

• Anyone who spends most of the day in offices and indoor spaces.
• Anyone taking a calcium supplement who wants it directed to bone rather than arteries.
• Women from their forties onward focused on bone density.
• Anyone using sunscreen constantly or wearing clothing that covers most of the body.
• Anyone who prefers one formula over buying vitamin D and vitamin K2 separately.

How to use

Take one tablet daily with a meal containing some fat, since vitamin D3 and vitamin K2 are both fat soluble and their absorption depends on dietary fat in the same meal. Taking the tablet with lunch, or with a meal containing olive oil, eggs or nuts, serves bioavailability better than an empty stomach. Keeping to the same time each day is recommended.

Frequently asked questions

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

The MK-7 form of vitamin K2 used by EVO Nutrition carries a longer side chain that keeps it in the blood far longer, so one daily intake is sufficient. MK-4 has a short circulating life and needs to be split across more than one time in the day.

Why is vitamin K2 combined with vitamin D3?

Vitamin D3 increases the amount of calcium absorbed from the intestine, and vitamin K2 activates the proteins that deposit that calcium into bone. Combining them in one tablet ensures the incoming calcium has something to direct it to the right place.

What is the difference between vitamin D3 and vitamin D2?

Vitamin D3 is cholecalciferol from an animal source, the same form skin makes under sunlight, while vitamin D2 is ergocalciferol from a fungal source. The D3 form used here is more effective at raising and maintaining blood 25-hydroxyvitamin D.
