Vitamin D3 + K2Vitamin D & K Food Supplement

What Vitamin D3 + K2 Bloom Is

Vitamin D3 + K2 Bloom pairs two fat-soluble vitamins in a single daily supplement, in the coral pouch that identifies it across the range. It is sold in three pack sizes, and the product inside each is the same.

Why D3 And K2 Are Sold Together

These two are frequently combined, and the reason is chemical rather than promotional: both are fat-soluble vitamins, which means they dissolve in fat rather than in water. Water-soluble vitamins such as vitamin C and the B group are handled differently by the body from fat-soluble ones, and the practical consequence for you is that fat-soluble vitamins are usually suggested to be taken with a meal that contains some fat.

Pairing them in one product is therefore a convenience decision: two vitamins that suit the same moment in the day, in one serving instead of two.

D2, D3, And Why The Letter After The D Matters

Vitamin D comes in two forms that appear on labels. D2 (ergocalciferol) is typically derived from yeast or fungi. D3 (cholecalciferol) is the form most commonly supplied in supplements.

D3 itself has two common sources. Most D3 on the market is derived from lanolin, the oil from sheep's wool, which means it is not suitable for vegans. D3 can also be produced from lichen, which is plant-based and is how a vegan D3 is made. This is a genuine difference, not a marketing one, and it is the reason our range carries a separate vegan D3 product rather than relabelling this one.

K1 And K2 — Also Not The Same Letter Twice

Vitamin K also splits into forms. K1 (phylloquinone) is the form found in leafy green vegetables. K2 (menaquinone) is found in fermented foods and some animal products, and it is the form used in supplements of this type. Within K2 there are further sub-forms, usually written as MK-4 and MK-7, which differ in origin and in how long they persist once taken.

None of this is trivia. If you are comparing two D3 and K2 products, the things that actually differ between them are the source of the D3, which sub-form of K2 is used, and the amount of each per serving. Those three lines on a label tell you more than anything printed on the front of a pack.

How Vitamin D Is Measured

Vitamin D is written two ways, and both appear on labels. IU stands for International Units, an older measure still widely used. µg or mcg is micrograms, the metric measure used in nutrition labelling.

They describe the same thing at a fixed relationship: 1 µg of vitamin D equals 40 IU. So 25 µg is the same as 1000 IU, and 100 µg is the same as 4000 IU. If you are comparing products, convert them to the same unit first — a pack showing a large IU figure and a pack showing a small µg figure may be identical.

How It Fits Into Your Routine

Fat-soluble vitamins are generally taken with a meal, which makes this one easy to anchor: it attaches itself to a mealtime rather than needing a slot of its own. In the United Kingdom, a vitamin D supplement is commonly taken year-round by some people and seasonally by others.

What You Get In Each Pack

A single pack, a 2 pack and a 4 pack. Identical product in each; only the quantity changes. Prices are shown on this page before you add anything to your basket.

Who It's For

Adults who want vitamin D3 and vitamin K2 in one daily supplement rather than two, and who want to see the form of each written out.

If you follow a vegan diet, check the source of the D3 before buying any vitamin D product, including this one — the vegan D3 in our range exists precisely because the default source is not plant-based.

Questions, Answered

What is the difference between vitamin D2 and D3?
D2 (ergocalciferol) is usually derived from yeast or fungi. D3 (cholecalciferol) is the form most commonly used in supplements.

Is vitamin D3 vegan?
Not usually. Most D3 is derived from lanolin, which comes from sheep's wool. D3 made from lichen is plant-based, which is why a separate vegan product exists in our range.

What is the difference between vitamin K1 and K2?
K1 is the form found in leafy greens. K2 is found in fermented foods and some animal products, and is the form used in supplements of this type. K2 is further divided into sub-forms, commonly written as MK-4 and MK-7.

How do I convert IU to micrograms for vitamin D?
1 µg equals 40 IU. So 25 µg is 1000 IU, and 100 µg is 4000 IU.

Why are D3 and K2 sold in one product?
Both are fat-soluble vitamins that suit the same moment in the day, so combining them saves taking two things.

Should I take it with food?
Fat-soluble vitamins are generally suggested to be taken with a meal containing some fat. Follow the directions given on the pack.

Can I take it alongside other BLOOMLY products?
Follow the directions for each separately, and speak to your doctor first if you take prescribed medication — vitamin K in particular is one to raise with your doctor if you take anticoagulant medication.

What is the difference between the pack sizes?
Quantity only.
