Why is this so much more expensive than the bottle that is a mixture of both vitamin d and k2?

This is mixed with D3 (I hope, & not D1) and D3 is cheap to buy.By adding D3, which I think dilutes the K2 Mk-4, your getting what you pay, Very little Mk-4K2 Mk-4 only, last a Long Time..I can only take 5 to 6 drops at a time, twice aday, with a little healthy fat... K2-Mk-4 takes the calcium from your arteries to your bones, teeth etc.If you want the best results , Just buy the K2 Mk-4.

The shear cost of K2 is extremely high. Blending it down by adding in Vitamin D lowers the overall cost. If you need a higher dose of K2, the product is offered so that you don't blow through bottles of D/K2 to achieve the proper dose. You can also use far less of the K2 alone if you are supplementing with D3 separately. Your health practitioner should be able to advise you of the proper dose for both.

Vitamin K has multiple uses. K1, most commonly found in green leafy vegetables, can be used to treat deficiencies that result in blood not clotting. K2 helps your body absorb calcium better in order to treat or prevent osteoporosis. For the latter, it comes in two forms. The MK4 is a synthetic, but the MK7 is derived from Natto (fermented soybeans) and is better utilized by the body. NOTE: This formula cannot be used by anyone on Coumadin (warfarin) or other blood thinners. I used this formula when my regular source of K2 MK7 was not available.

Actually, if you get the 2pk bottle set, you get 250 packets which saves you $3-4 over buying 2 of these boxes and gives you 2 free bottles. This price is for this item is about 50% higher than a normal drug store.

Pure Encapsulations Vitamin D3 is a product that my doctor was selling from his shelf for twice the price I pay online. So, it's helpful to find the product online.

I noticed that the blue bottle contains 0.5 fl oz (15 ML) while this white bottle contains 1 fl oz (30 ML) for nearly the same $60 price.

I cannot see any information mentioning Vitamin K, but that would be in eggs if I remember correctly and there are eggs in this. I have uploaded an image of the label an you can call them (Unilever) @ 1-800-416-3275. Sorry I can't be more helpful, but I hope you can get the information you need when you call them. Have a great week!

Vitamin D is actually dispensed in units called "International Units". Some patient and doctors refer to the units as milligrams (mg) because it is easier to remember/understand. If you are looking for 2000 mg of Vit D you can feel comfortable purchasing 2000 IU of Vit D. They are the same thing.

I am a physician with a personal interest in Vitamin D research, here's the skinny: There is only one form of prescription vitamin D- ergocalciferol (D2) 50,000 IU. This product is cholecalciferol (D3) 50,000 IU and is not chemically identical. There is strong evidence, however, that the OTC form (D3) is superior to the Rx form (D2) in both absorption rates and sustained effect. In addition, the Rx form (D2) is not what the human body creates on it's own, it makes D3. While both will raise the total level of Vit-D-25-OH tested on vitamin D blood assays, only the OTC D3 form significantly raises the naturally formed isomer of D3. I know of no research that investigates whether elevated D2 levels have the same health benefits as are seen with elevated natural D3 levels. Ergocalciferol was grandfathered in as a drug by the FDA in 1940 when they started regulating medications, and has been used since out of habit. Most doctors are not well educated on this subject and prescribe the Rx form as it is the only formulation able to be prescribed, and because it is dogma. In short, this OTC form of cholecalciferol D3 is better absorbed, longer lasting, cheaper, more accessible, and a match to naturally produced human vitamin D analogues. It can be safely substituted for ergocalciferol D2 prescribed by your doctor.

The back of my bottle says Vitamin D and Vitamin K and lists no other ingredients.

When I ordered it here the bottle was 2000 IU per drop, though this product also comes in 1oz size with 500 IU drops ~ for usually 2/3 to 3/4 of the price, so the 2000 IU is more affordable. I don't see the point of the 500 IU myself since I think most of the population these days need 2000-10,000 IU to bring their Vitamin D levels to optimum. Though it would be good for a child dose or if you only need 1000 or 2000 IU in the summertime one might want to split that dose up throughout the day ~ but it's more expensive that way. To know for sure, I would ask the seller this question as only they will really know.

It most likely has to do with the cost to produce either supplement. Pricing is ultimately determined by the manufacturer, Now Foods.

Since it is no longer in available in the stores and the price for one bottle is just out of sight. It's very costly. I loved this product and don't understand why it is no longer available in stores for a more reasonable price. I won't pay that kind of money for this product.

If you are having a problem with the pricing structure, may I suggest that you try one of Walgreens senior multivitamin supplements. They are more than equal to the Centrum products and offer very good value pricing (and they periodically have 2 for 1 sales).

I noticed a large discrepancy in the two answers already given, so I'll try to clarify the confusions. The label states (not "drops" but "servings") "Servings Per Container: 80" and also states "Serving Size: Fifteen Drops" and "Fifteen Drops Contain: Vitamin K (as Vitamin K2 Menatetrenone) 15mg". So at the rate of 45mg/day, the 1200 drops/bottle would indeed last 26+ days or about a month; however the math at 5 drops/day would last 240 days or about 8 months. While some may use as little as 1 or 2 mg/day, at my actual use rate of 7drops/day a bottle has consistently lasted just under 6 months which fits with the math that works out to 171+ servings.
