Vitamin D3 1000IU Bloom

What Vitamin D3 1000IU Bloom Is

Vitamin D3 1000IU Bloom is a daily vitamin D food supplement. The strength appears in the name because with vitamin D the strength is the main thing people are choosing between — and because there is no good reason to make you hunt for it.

Reading The Two Units: IU And Micrograms

Vitamin D is written two ways on labels, and it causes more confusion than any other nutrient in the range.

IU stands for International Units, an older measure still in wide use. µg or mcg stands for micrograms, the metric measure used in nutrition labelling in the United Kingdom and Europe.

They are not competing systems — they describe the same thing at a fixed ratio:

• 1 µg of vitamin D = 40 IU
• 25 µg = 1000 IU
• 50 µg = 2000 IU
• 100 µg = 4000 IU

So a pack showing a large IU figure and a pack showing a small microgram figure may be describing exactly the same amount. Convert both to the same unit before you compare them. This is also the most common reason people think they are comparing two different strengths when they are not.

D2 And D3 — Not The Same Vitamin

D2 is ergocalciferol, typically derived from yeast or fungi. D3 is cholecalciferol, and it is the form used in most vitamin D supplements, including this one.

D3 itself has two common sources, and this is the difference that decides whether a product suits you. Most D3 comes 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 that is how a genuinely vegan D3 is made.

Our range carries a separate vegan D3 product for exactly this reason. It is a different raw material, not a different label.

Why Vitamin D Comes Up So Much In The United Kingdom

Vitamin D is unusual among vitamins in that the body can produce it through skin exposure to sunlight, as well as obtaining it from food. Dietary sources are relatively few — oily fish, egg yolk, liver, and foods that have been fortified with it, such as some spreads and cereals.

At the latitude of the United Kingdom, the amount of usable sunlight varies substantially between summer and winter. That seasonality is the reason vitamin D is discussed here more than in sunnier countries, and the reason many people take it in the darker months specifically.

Choosing Between 1000 IU And 4000 IU

Our range carries both strengths, and the difference between them is quantity, not quality.

1000 IU is the lower of the two and is the more common everyday choice. 4000 IU is the higher strength. There is also a vegan option at the lower strength. All three are vitamin D3.

Which suits you is a question for your doctor or pharmacist rather than for a product page, particularly if you already take a multivitamin or any other product containing vitamin D — that is the most common way people end up taking more than they intended.

How It Fits Into Your Routine

Vitamin D is fat-soluble, so it is generally suggested to be taken with a meal containing some fat. That makes it one of the easier supplements to remember: it attaches to a mealtime rather than needing a slot of its own.

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 a lower-strength daily vitamin D3 supplement. If you follow a vegan diet, choose the vegan D3 in our range instead — standard D3 is usually derived from lanolin.

Questions, Answered

How do I convert IU to micrograms for vitamin D?
1 µg equals 40 IU. So 25 µg is 1000 IU, 50 µg is 2000 IU, and 100 µg is 4000 IU.

Is 1000 IU the same as 25 micrograms?
Yes. They are two ways of writing the same amount.

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

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

Why is vitamin D talked about more in the United Kingdom?
Because the body can produce it through skin exposure to sunlight, and usable sunlight at this latitude varies a great deal between summer and winter.

Which foods contain vitamin D?
Oily fish, egg yolk and liver, plus foods that have been fortified with it such as some spreads and cereals.

Should I choose 1000 IU or 4000 IU?
That is a question for your doctor or pharmacist, particularly if you already take a multivitamin or another product containing vitamin D.

Should I take it with food?
Vitamin D is fat-soluble and is generally suggested to be taken with a meal containing some fat. Follow the directions given on the pack.
