Vitamin D3 + K2: how to compare a two nutrient pack

Comparing a combination capsule: two panel rows, mixed units, the named K2 form, and pack against pack pricing.

A combination pack is two label rows

The product name tells you which nutrients are in the capsule. The panel on the back tells you how much of each, and those are different pieces of information.

Read both rows before comparing anything. A pack can carry a generous figure in one row and a small one in the other, and the name on the front will look identical either way.

Mixed units inside one panel

Vitamin D is often written in micrograms and international units together. Vitamin K2 is normally written in micrograms only.

That means a single panel can contain three different unit styles. Convert before you compare, and never line up an IU figure against a microgram figure as though they were the same scale.

The K2 form is named, so look for it

Vitamin K2 reaches a label as a menaquinone, and the two you will usually see written out are MK-7 and MK-4.

A label that states K2 as menaquinone-7 has told you something a label saying only vitamin K2 has not. The ingredients list will also show whether that menaquinone arrives in an oil or on a dry carrier.

Find the menaquinone designation, not just the letter K
Note whether the stated amount is the nutrient or a preparation containing it
Check the ingredients list for the carrier and the capsule shell material

One combination pack against two single packs

The honest comparison here is pack sizes and pack prices side by side: this 60 capsule combination against a pack of Vitamin D3 and a pack of Vitamin K2 bought separately.

Compare the stated amount in each row with the stated amount on each single pack, and read each label's portion before doing any per portion maths.

What is inside the shell

Capsules list a shell material in the ingredients, commonly a plant cellulose or gelatin, alongside any oil, bulking agent or anti caking agent.

The allergen statement sits with that list and has to declare any of the regulated allergens present. A blank space is not the same as a confirmed absence.
