Vitamin D3 5000 IU + Vitamin K2 100 mcg | Vegan, with Coconut Oil | 60 Capsules | Sports Research

Vitamin D3 5000 IU with Vitamin K2 100 mcg from Sports Research comes in a bottle of 60 vegan capsules in coconut oil, a formula pairing two fat-soluble vitamins that sit at opposite ends of a single route: the calcium route. Vitamin D3 raises how much calcium crosses into the blood, and vitamin K2 directs that calcium to where it belongs. It is sought by anyone taking a high dose of vitamin D who wants a fitting companion for it, and by anyone looking for vitamin D3 from a non-animal origin.

What is vitamin K2?

Vitamin K2 (Vitamin K2) is a fat-soluble vitamin belonging to the menaquinone group (Menaquinones), and it parts ways with vitamin K1 from leafy greens in its destination inside the body. Vitamin K1 heads mostly to the liver, while vitamin K2 reaches bone tissue and vessel walls and lingers in circulation for a longer stretch. Its dietary sources are limited, the best known being fermented foods and aged cheeses.

Benefits of vitamin D3 with vitamin K2

• Bone mineralisation support: the formula combines raising calcium intake and steering it toward bone tissue in a single step.
• Vascular integrity support: vitamin K2 is associated with keeping calcium away from soft tissues and artery walls.
• Immune support: immune cells carry receptors specific to vitamin D that participate in tuning their response.
• Muscle strength support: vitamin D receptors are present in the skeletal muscle cell and are linked to its performance.
• Dental support: enamel mineralisation relies on the same calcium route on which vitamin D3 and vitamin K2 act.
• Mood support: vitamin D receptors are spread across brain regions associated with mood regulation.
• Fully vegan formula: the vitamin D3 source in the Sports Research product is plant-derived, the hardest element to supply in this category.

Active ingredients

• Vitamin D3 — 5000 IU: raises the efficiency of drawing calcium and phosphorus from the intestine and participates in tuning immune cell activity.
• Vitamin K2 — 100 mcg: activates the carboxylation-dependent proteins that grip calcium and fix it into bone tissue.
• Coconut oil: supplies inside the capsule the fatty medium that two water-insoluble vitamins require.

How vitamin D3 and vitamin K2 work inside the body

Vitamin D3 needs two stages of activation before it can act: a hydroxylation in the liver and then another in the kidney. Once activation is complete, the active form meets a nuclear receptor inside the intestinal lining cell and directs it to manufacture a calcium-transport protein, and at this point more calcium crosses into the blood. Vitamin K2 enters the picture at the next stage, acting as a cofactor for an enzyme that adds a carboxyl group to glutamic acids in two proteins: osteocalcin (Osteocalcin) in bone and matrix Gla protein (Matrix Gla Protein) in the vessel wall. With that addition alone the protein gains its ability to grip a calcium ion and steer it to its place.

What sets this formula apart

The Sports Research capsule is built on three formulation decisions: a high vitamin D3 dose of 5000 IU, the addition of 100 mcg of vitamin K2 instead of presenting vitamin D alone, and the adoption of a plant source for vitamin D3 itself. The third decision is the heaviest one industrially, because the common form of vitamin D3 is extracted from an animal origin, so a plant-derived form opens the door to anyone excluding animal sources from their diet. Coconut oil inside the capsule carries both vitamins in a ready fatty medium, so the outcome is not left hanging on how much fat sits in the user's meal.

Who is this product for?

• Anyone taking a high dose of vitamin D who wants vitamin K2 alongside it.
• Vegans looking for vitamin D3 from a non-animal origin.
• Anyone with limited sun exposure because of indoor work.
• Anyone interested in bone tissue and vascular integrity in one formula.
• Anyone who prefers a single daily capsule over several separate bottles.

How to use

Take the vitamin D3 with vitamin K2 capsule alongside the fattiest meal of the day, because both vitamins dissolve in fat and their absorption depends on the bile released in response to a fat-containing meal. Keeping the daily timing consistent matters more than the particular hour. Anyone taking vitamin K antagonist blood thinners should consult their doctor before starting. Follow the dose printed on the bottle.

Frequently asked questions

What is the difference between vitamin K1 and vitamin K2?

Vitamin K1 comes from leafy greens and its main destination is the liver, where it participates in activating clotting factors, while vitamin K2 reaches bone tissue and vessel walls and stays in the blood longer. It is precisely this difference that makes vitamin K2, not vitamin K1, the one paired with vitamin D3 in formulas.

Why is the vitamin D3 capsule suspended in oil?

Vitamin D3 and vitamin K2 do not dissolve in water, and the coconut oil inside the Sports Research capsule places both vitamins in a fatty medium ready for absorption from the moment of swallowing. That reduces how far the outcome depends on the amount of fat present in the user's meal.

Can this formula be taken with blood thinners?

Vitamin K2 interacts with vitamin K antagonist blood thinners, so this formula should not be started without reviewing it with the treating doctor. The issue concerns vitamin K2 alone and has no bearing on vitamin D3.

Cautions
