Biotin Bloom

What Biotin Bloom Is

Biotin Bloom is a daily biotin food supplement, in the pink pack that places it on the beauty shelf of the BLOOMLY range. It is sold in three pack sizes, and the product inside each is the same.

What Biotin Is

Biotin is a vitamin. Specifically it is vitamin B7, part of the B group, and you will occasionally still see it written as vitamin H — an older name that survives on some labels and in a lot of older writing. B7, H and biotin are three names for the same vitamin.

Like the rest of the B group it is water-soluble, which is a meaningful distinction rather than a technicality. Water-soluble vitamins are not stored in fat the way vitamins A, D, E and K are, which is why they are generally taken as a regular daily habit rather than occasionally.

Biotin occurs in a range of everyday foods: eggs — particularly the yolk — nuts, seeds, oily fish, liver, sweet potatoes and some pulses.

Why The Numbers On Biotin Packs Look So Large

Biotin is measured in micrograms, written as µg or mcg. A microgram is one thousandth of a milligram, so figures that look enormous on a biotin pack are small in absolute terms — 10,000 µg is 10 mg.

This is worth knowing for two reasons. It explains why biotin packs advertise numbers that look dramatic next to a mineral pack, and it means a percentage of the Nutrient Reference Value is a far more informative comparison than the raw microgram figure.

One Thing Worth Raising With Your Doctor

There is a practical point about biotin that has nothing to do with how it is marketed and rarely gets mentioned on the pack.

Biotin taken as a supplement is known to interfere with certain laboratory blood tests, producing results that do not reflect what is actually happening. If you are having blood tests, it is worth telling the person taking the sample that you take a biotin supplement, and worth asking your doctor whether to pause it beforehand.

We mention it because it is genuinely useful and because nobody selling biotin seems to.

How It Fits Into Your Routine

Water-soluble vitamins suit a consistent daily slot. Most people attach biotin to a meal or to a morning routine and leave it there.

It sits on the beauty shelf of the range alongside Collagen Bloom, and the two appear together in one of our multi-product edits if you would rather try them as a pair.

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 straightforward daily biotin supplement and would rather understand what the vitamin is than be told what it will change.

Questions, Answered

What is biotin?
A water-soluble B vitamin, also known as vitamin B7 and, in older labelling, vitamin H.

Is biotin the same as vitamin B7 and vitamin H?
Yes. Three names, one vitamin.

What foods contain biotin?
Eggs, especially the yolk, along with nuts, seeds, oily fish, liver, sweet potatoes and some pulses.

Why are biotin amounts written in micrograms?
Because the quantities involved are very small. A microgram is one thousandth of a milligram, so 10,000 µg is 10 mg.

What is the difference between µg and mcg?
None. They are two ways of writing micrograms. "µg" is standard in the United Kingdom and Europe; "mcg" is more common in the United States.

Does biotin affect blood tests?
Biotin supplements are known to interfere with some laboratory blood tests. Tell whoever takes your sample that you take biotin, and ask your doctor whether to pause it beforehand.

Why is biotin water-soluble rather than fat-soluble?
It is part of the B group, all of which dissolve in water rather than fat. This is why B vitamins are generally taken as a regular daily habit.

Can I take it alongside other BLOOMLY products?
Many people do. Follow the directions for each product separately, and speak to your doctor first if you take prescribed medication, are pregnant or are breastfeeding.
