Vitamin D3 Liquid 5000 IU + K2 Complex (MK4 + MK7) 125 mcg | per 5 drops | with Olive Oil | 90-Day Supply | 20 ml | Osende

Osende Vitamin D3 5000 IU with Vitamin K2 125 mcg per 5 drops in an olive oil base comes in a 20 ml bottle covering 90 days, a liquid formula pairing a high-strength vitamin D3 dose with a vitamin K2 complex that steers calcium toward bone. The drop format allows precise adjustment a tablet cannot offer, and the olive oil base carries both fat-soluble vitamins within the dose itself. It suits adults with limited sun exposure who want concentrated bone and immune support in one daily dose.

What is a vitamin D3 and K2 complex?

Vitamin D3, cholecalciferol, is a fat-soluble vitamin that behaves like a hormone, and its job is to raise the amount of calcium passing from the intestine into the blood. Vitamin K2 is the menaquinone family, best known in the MK-4 and MK-7 forms, and its job is to activate the proteins that decide where that calcium ends up. Combined in one formula, the first supplies the material and the second directs it.

Benefits of vitamin D3 5000 IU with K2

• Vitamin D status support: a 5000 IU daily amount is aimed at those with little sun exposure who want steady daily support.
• Calcium directed to bone: vitamin K2 activates osteocalcin, the protein that fixes calcium in bone tissue.
• Arterial flexibility support: vitamin K2 activates matrix Gla protein, which resists calcium deposition in the vessel wall.
• Immune support: vitamin D3 receptors are distributed across immune cells, including those of the first line of defence.
• Muscle strength and balance support: vitamin D3 is linked to muscle fibre function and postural stability.
• Dental health support: vitamin D3 and vitamin K2 both take part in mineralising dental tissue.
• Mood and energy support: vitamin D3 levels are linked to circadian rhythm and general wellbeing.

Active ingredients

• Vitamin D3 5000 IU per 5 drops: the cholecalciferol form, responsible for raising calcium and phosphorus absorption from the intestine.
• Vitamin K2 125 mcg per 5 drops: a complex combining the MK-4 and MK-7 menaquinone forms, activating vitamin K dependent proteins in bone and artery.
• Olive oil: the carrier base supplying the lipid medium both vitamins need for absorption.

How vitamin D3 and K2 work in the body

The division of labour between the two is clear. Vitamin D3 stimulates production of osteocalcin in bone-building cells and raises the calcium arriving from the intestine, but that protein leaves the cell inactive until vitamin K2 carboxylates it, at which point it can grip calcium and fix it into bone tissue. Vitamin D3 makes the tool and vitamin K2 switches it on. Being fat soluble, both cross the intestinal wall inside lipid micelles, which the olive oil base supplies directly within the drop.

What sets this formula apart

The Osende formula is liquid rather than a tablet, so the dose is adjustable drop by drop: five drops give the full amount, and it can be reduced or increased as a doctor directs based on test results, a flexibility a compressed tablet cannot match. The vitamin K2 here is also a complex of both MK-4 and MK-7 rather than a single form. MK-7 carries a longer side chain that keeps it circulating for a long time, reaching distant bone and vessel tissue, while MK-4 is short lived and acts locally in the tissue it reaches quickly. The 20 ml bottle covers 90 days at one daily dose.

Who is this product for?

• Anyone working indoors with insufficient sun exposure.
• Anyone who finds tablets hard to swallow and prefers drops.
• Anyone tracking vitamin D by blood test who needs an adjustable dose.
• Anyone taking a calcium supplement who wants it directed into bone.
• Anyone who prefers one formula over separate vitamin D and vitamin K2 products.

How to use

Take 5 drops once daily, preferably after a meal containing some fat, since vitamin D3 and vitamin K2 are both fat soluble and absorb better alongside dietary fat. Shake the bottle before use and keep to the same time each day so levels stay steady. A 20 ml bottle at this dose covers 90 days.

Frequently asked questions

Why a complex of MK-4 and MK-7 rather than one form?

The vitamin K2 complex in the Osende formula combines both forms: MK-7 stays in the blood far longer thanks to its extended side chain and reaches distant tissue, while MK-4 is shorter lived and acts locally where it arrives quickly. Combining them covers both timeframes instead of relying on one.

Why drops instead of tablets for vitamin D3?

Osende drops allow the amount to be adjusted one drop at a time, raising or lowering it as a doctor directs, which a tablet only allows by splitting. Drops also suit anyone who struggles to swallow tablets, and they arrive in a lipid base ready for absorption.

Do the drops need to be taken with food?

Osende vitamin D3 and K2 drops are best taken after a meal containing fat, because absorption of both fat-soluble vitamins rises when dietary fat is present. The olive oil base helps, but a fat-containing meal remains the better option.
