Biotin Gummies: 130µg of Vitamin B7 in Your Daily GUUDIES Pouch

Last reviewed 25 October 2026.

Biotin gummies are chewable supplements that supply vitamin B7. In the daily GUUDIES pouch, biotin comes in two of the six gummies: 100µg in Marine Collagen and a further 30µg in Daily Greens+, so 130µg a day in total. Biotin contributes to the maintenance of normal hair and normal skin.

What are biotin gummies?

Biotin gummies are a chewable way to take vitamin B7, usually on their own or alongside collagen. GUUDIES takes a different approach: rather than a single-ingredient biotin gummy, biotin sits inside two of the six gummies in one daily pouch, next to marine collagen, a multivitamin and greens, mushrooms, sea moss, apple cider vinegar and saffron. All six gummies are pectin based, so there is no gelatine.

What biotin does: the authorised claims

In Great Britain, only health claims on the GB nutrition and health claims register can be made for a food supplement. For biotin, the authorised claims include that it contributes to:

• the maintenance of normal hair
• the maintenance of normal skin
• the maintenance of normal mucous membranes
• normal energy-yielding metabolism
• normal functioning of the nervous system
• normal psychological function

These claims apply when a daily serving provides at least 15% of the NRV. The GUUDIES pouch provides 260%.

What biotin is

Biotin is one of the eight B vitamins, water soluble like the rest of them. It is also known as vitamin B7, and in older literature as vitamin H, from the German Haar und Haut, hair and skin, which tells you something about how it has been marketed for a long time.

Who biotin gummies suit, and who they don't

Worth saying plainly, because the supplement category rarely does: biotin deficiency is uncommon in people eating a normal varied diet. Biotin is found in eggs, nuts, seeds, salmon, sweet potato and liver, and gut bacteria produce some as well (NIH Office of Dietary Supplements: Biotin). The NHS says most people should be able to get the biotin they need from their diet.

The unusual exception is raw egg white, which contains avidin, a protein that binds biotin and blocks its absorption. Eating raw eggs in quantity over a long period is one of the few reliable ways to become deficient. Cooking destroys the avidin.

So a biotin gummy suits someone who wants a simple daily routine that includes biotin alongside other nutrients. It is not a fix for hair loss with a medical cause; if you are losing hair suddenly or in patches, speak to your GP.

The biotin in the pouch is mostly in the Marine Collagen gummy, which contains fish. If you are vegan or have a fish allergy, leave that gummy out and you still get 30µg of biotin from the vegan Daily Greens+ gummy.

How much biotin is too much?

The NHS advises that taking 0.9mg (900µg) or less of biotin a day from supplements is unlikely to cause any harm. The GUUDIES pouch provides 130µg, well under that figure. If you take a separate hair, skin and nails supplement as well, add up the biotin in both labels.

Biotin can interfere with blood tests

This one matters and is not widely known. Biotin can distort the results of certain laboratory tests, including some thyroid and cardiac tests, because those assays use biotin in their chemistry (NIH ODS). It does not change anything in your body, it changes what the machine reports.

If you are having blood tests, tell whoever is taking them that you take a supplement containing biotin. They may ask you to stop for a short period beforehand.

How to take biotin gummies

Take the whole pouch once a day, with or after food. Biotin is water soluble, so timing matters less than taking it every day. Each GUUDIES pack holds 28 daily pouches. Do not exceed the stated dose. Formulated for adults aged 18 and over; if you are pregnant, breastfeeding or taking prescription medication, check with your GP first. Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle.

Why biotin appears twice

Biotin is declared separately in each gummy rather than combined into a single figure, so the label shows exactly where it comes from. Added together that is 130µg across the daily pouch.

Common questions

How much biotin is in GUUDIES?

100µg in the Marine Collagen gummy and 30µg in Daily Greens+, so 130µg across the daily pouch, which is 260% of the NRV.

Do biotin gummies help hair growth?

Biotin contributes to the maintenance of normal hair and normal skin. That is the authorised claim in Great Britain. Biotin deficiency is uncommon, and there is little evidence that extra biotin speeds up hair growth in people who are not deficient.

What is biotin?

Vitamin B7, one of the eight water soluble B vitamins. Also known historically as vitamin H.

Is biotin deficiency common?

No. It is uncommon in people eating a normal varied diet, since biotin is found in eggs, nuts, seeds, fish and sweet potato, and gut bacteria produce some too.

How much biotin is safe to take a day?

The NHS advises that 0.9mg (900µg) or less a day from supplements is unlikely to cause harm. GUUDIES provides 130µg.

Does biotin affect blood tests?

It can. Biotin may distort some laboratory results, including certain thyroid and cardiac assays. Tell whoever takes your blood that you take a supplement containing it.

Are GUUDIES biotin gummies vegan?

The biotin itself is. The Marine Collagen gummy that carries most of it is not, since it contains collagen from fish. The Daily Greens+ gummy is vegan and carries 30µg.
