Vitamin D3 4000 IU + K2, MCT, drops 50 ml

Vitamin D3 4000 IU + K2, MCT oil drops 50 ml

This is a preparation for someone looking for a high concentration of vitamin D and wants it paired with vitamin K2. The daily portion is four applications, in which the manufacturer declares 100 µg of vitamin D, which is 4000 IU, and 75 µg of vitamin K, corresponding to 2000% and 100% of the reference intake value, respectively. The 50 ml bottle translates to 125 daily portions. The carrier is MCT oil from coconut, as both vitamins dissolve in fats. The raw materials are specified by name: vitamin D comes from lanolin and is marked as Quali-D, while vitamin K comes from chickpeas, as MenaQ7 in the MK-7 variant. At this dosage, it is particularly important to whom the manufacturer directs the preparation and to whom it does not. The manufacturer answers this question twice and not entirely consistently, and both answers stand next to each other. We return to them below, in the description of the target group and in the safety information.

Ingredients

The full list provided by the manufacturer:

• MCT oil from coconut (medium-chain triglycerides of fatty acids)
• Menachinone-7 (vitamin K from chickpeas, MenaQ7 as K2 MK-7)
• Cholecalciferol (vitamin D from lanolin, Quali-D)
• Antioxidant: a mixture of tocopherols

Four items and none unnecessary, which the manufacturer summarizes with the term clean label. MCT oil is the carrier, without which the absorption of both vitamins would depend on the fat content of the meal. Vitamin K2 in the MK-7 variant from chickpeas stands here next to vitamin D not by chance, as this combination is one that the manufacturer leads in several of its preparations, and to which we dedicated a separate article on the blog. The mixture of tocopherols protects the contents of the bottle from oxidation. The manufacturer provides three health claims: vitamin D helps in the proper functioning of the immune system, vitamin D helps maintain healthy bones and teeth, and vitamin K helps maintain healthy bones and contributes to normal blood clotting. All three refer to the ingredients that are actually listed here, and the manufacturer attributes them by name to vitamin D or vitamin K. The bottle translates to 125 daily portions of four applications.

How to use

The manufacturer states this briefly: shake the bottle well before use, measure the recommended portion, and add it to water or another cool liquid. The daily portion is four applications and should not be exceeded. Shaking is practically important, as the contents in the oil separate between uses.

Settling in the bottle is normal, and the manufacturer describes it as evidence of natural ingredients.

For whom

At a dose of 4000 IU, the question of the target group is more important than usual, and the manufacturer’s card answers it twice and not entirely consistently. Once it states that the product is not recommended for children and adolescents under 18 years of age and for pregnant and breastfeeding women. The second time, a few lines below, that the supplement is intended for healthy individuals over 75 years of age, which significantly narrows the group. Both lines stand on the same page, so we quote them together and leave the resolution to the doctor. Regardless, the manufacturer recommends testing 25-(OH)D in the blood before starting supplementation and consulting the result, and regarding vitamin K2, indicates one clear contraindication: anticoagulants with vitamin K antagonists. It is worth taking this warning seriously, as it concerns medications taken chronically, not acutely. The manufacturer also recommends that before starting supplementation, a 25-(OH)D blood test be performed.

Frequently asked questions

Who is this preparation for?

The manufacturer provides two answers on the same page. The first excludes children and adolescents under 18 years of age and pregnant and breastfeeding women. The second narrows the group to healthy individuals over 75 years of age. We do not resolve this discrepancy for the manufacturer, so at this dosage, talking to a doctor is the right step.

How much vitamin D is in the daily portion?

One hundred micrograms, or 4000 IU, which the manufacturer translates to 2000% of the reference intake value. The portion is four applications. In the same portion, there is 75 µg of vitamin K, which is 100% of the reference intake value. According to the manufacturer, the 50 ml bottle is sufficient for 125 such portions.

Why is vitamin K2 alongside vitamin D?

This is a combination that the manufacturer leads in several of its preparations, and vitamin K is responsible for a separate health claim: it helps maintain healthy bones and contributes to normal blood clotting. Here it comes from chickpeas and is present in the MK-7 variant, marked with the MenaQ7 sign.

Do I need to check anything before starting?

The manufacturer recommends performing a 25-(OH)D blood test and consulting the result with a doctor or pharmacist before starting supplementation. Separately, it warns that the preparation should not be consumed by individuals taking anticoagulants containing vitamin K antagonists, such as warfarin or acenocoumarol. Both of these recommendations are provided by the manufacturer on the product card, in separate paragraphs.

Variants and category

The manufacturer also offers the same dose without vitamin K and in a smaller bottle and in capsules, as well as a separate variant that is half as strong. Other vitamins can be found in the vitamins category.

Safety and storage

The manufacturer states that the product is not recommended for children and adolescents under 18 years of age and for pregnant and breastfeeding women, and in another place on the same card, that the supplement is intended for healthy individuals over 75 years of age. The preparation should not be consumed by individuals taking anticoagulants containing vitamin K antagonists, such as warfarin or acenocoumarol. The manufacturer recommends that before starting supplementation, a 25-(OH)D blood test be performed and the result consulted with a doctor or pharmacist. The manufacturer warns that sediment may appear in the bottle and describes it as evidence of the presence of natural ingredients, not a defect in the product. Do not use the preparation if allergic to any ingredient. Store the bottle in a dry place, at room temperature, and out of reach of small children.

Do not exceed the recommended portion for consumption during the day. The dietary supplement does not replace a varied diet or a healthy lifestyle.
