Vitamin D3 4,000 IU + K2 100 mcg by Zipvit is a dietary supplement in a bottle of 365 tablets, with a single daily dose bringing together 4,000 IU of vitamin D3 and 100 mcg of vitamin K2 as MK-7. The 4,000 IU level sits in the moderate daily range chosen by people wanting long-term continuity rather than rapid correction. At 365 tablets, that is one a day across a full year with no reordering.
What are vitamin D3 and vitamin K2 MK-7?
Vitamin D3 is cholecalciferol, a fat-soluble vitamin the skin manufactures from a cholesterol derivative on exposure to UVB radiation. Vitamin K2 is menaquinone, and the number in MK-7 refers to the count of isoprene units in the molecule's side chain, a length that governs how it behaves in the blood. Neither dissolves in water, which is why their absorption is tied to the presence of dietary fat.
Benefits of vitamin D3 and vitamin K2
- Bone and teeth support: vitamin D3 and vitamin K2 together contribute to maintaining bones and teeth in their normal state.
- Normal calcium utilisation: vitamin K2 helps the body put calcium to use where it belongs.
- Muscle function support: vitamin D3 is tied to maintaining normal muscle function.
- Immune support: vitamin D3 takes part in the normal working of the immune system.
- Low-sunlight month support: skin synthesis of vitamin D falls when UVB exposure drops.
- Cell division support: vitamin D3 is involved in the process of normal cell division.
Active ingredients
- Vitamin D3 4,000 IU: cholecalciferol at a moderate daily level aimed at long-term continuity.
- Vitamin K2 100 mcg: menaquinone-7, activating the vitamin K dependent proteins that direct calcium.
How it works in the body
Vitamin D3 is held in the blood as 25-hydroxyvitamin D, the circulating form whose concentration reflects the body's status. Once converted to its active form, vitamin D3 behaves as a transcription factor: it binds the vitamin D receptor inside the cell nucleus, pairs with the retinoid X receptor, and the resulting complex binds specific regions of DNA and influences the expression of hundreds of genes. On the other side, vitamin K2 operates within a chemical loop known as the vitamin K cycle: it is consumed activating proteins such as Matrix Gla Protein and then recycled by the vitamin K epoxide reductase enzyme. Proteins activated this way are the ones that bind calcium ions and determine where they go within tissue.
What sets this formula apart
The most notable feature of the Zipvit formula is the dose level and the length of coverage taken together. At 4,000 IU, the vitamin D3 level is below rapid-correction doses and above token amounts, meaning it is aimed at continuous year-round use. Choosing MK-7 at 100 mcg rests on the side-chain length of that molecule, which gives it longer persistence in the blood than the short-chain MK-4 form that needs repeating through the day. The format is one tablet daily, and 365 tablets cover a full year of regular use.
Who is this product for?
- People wanting a moderate daily level to stay on all year rather than a short correction course.
- People who spend most daylight hours indoors.
- People already taking vitamin D who want vitamin K2 without a second separate tablet.
- Adults focused on bone and dental health and muscle function.
- People who prefer an annual bottle over reordering every couple of months.
How to use
One tablet daily of vitamin D3 4,000 IU + K2 100 mcg with water, preferably with a meal. Dietary fat in that meal is a practical requirement for absorbing both vitamins, since both are fat soluble. Anchoring the tablet to a fixed meal, lunch for instance, makes long-term consistency easier to hold.

Frequently asked questions
Is 4,000 IU of vitamin D3 suitable for long-term daily use?
The 4,000 IU vitamin D3 level sits in the moderate daily range aimed at year-round continuity rather than rapid correction of a confirmed shortfall. What suits any individual is for a doctor to determine based on a measured blood vitamin D level.
What does the number 7 in MK-7 mean?
The number in MK-7 refers to the count of isoprene units in the side chain of the menaquinone molecule. That chain length is what gives MK-7 longer persistence in the blood than the shorter-chain, faster-clearing MK-4 form.
Can the tablet be taken with water alone?
The vitamin D3 and K2 tablet is swallowed with water, but it is better taken with a meal containing fat. Both vitamins are fat soluble, and absorption depends on fat being present in the digestive tract at the time the tablet is taken.
