about this product.

Biotin is a water-soluble B vitamin — B7 — that plays a central role in keratin production, the structural protein that makes up hair, skin, and nails. This supplement provides 5000mcg per capsule, a dose commonly used when dietary intake or absorption is insufficient to meet the body's needs.

Most people get some biotin from food, but deficiency — or functional insufficiency — is more common than often assumed, particularly in people with poor gut absorption, those who consume raw egg whites regularly, or those in pregnancy. Symptoms can include thinning hair, brittle nails, and dry or flaky skin. A blood test can confirm low levels, though biotin status is not routinely checked on standard panels.

This supplement suits anyone who has noticed changes in hair density, nail integrity, or skin texture and wants to address a potential nutritional gap. It is also used by people in periods of higher physiological demand — postpartum recovery, for instance, or prolonged caloric restriction. Biotin at this dose is generally well tolerated, as excess is excreted in urine given its water-soluble nature.

One important clinical note: high-dose biotin supplementation is known to interfere with several common laboratory assays, including thyroid function tests and troponin measurements. If you are having blood tests, inform your clinician that you are taking biotin and consider pausing it for a few days beforehand.

frequently asked.

Who is most likely to benefit from a biotin supplement?

People with dietary gaps, poor gut absorption, or increased physiological demand — such as postpartum women or those on prolonged calorie restriction — are most likely to benefit. Changes in hair thickness, brittle nails, or dry skin can all be signs of insufficient biotin status.

Does biotin actually help with hair growth?

Biotin supports the production of keratin, the structural protein in hair. There is reasonable evidence that correcting a deficiency can improve hair quality and reduce shedding, though it is unlikely to dramatically accelerate growth in someone who is not deficient.

Can I take this alongside other supplements or medications?

Biotin is water-soluble and generally considered safe alongside most supplements and medications. That said, always check with your GP or pharmacist if you are on any prescribed treatments, particularly thyroid medication, as biotin can affect how certain lab results are interpreted.

Will high-dose biotin interfere with my blood tests?

Yes — this is clinically important. Biotin at 5000mcg can interfere with several common laboratory assays, including thyroid function tests and cardiac troponin tests. Let your clinician know you are taking it and consider pausing supplementation for a few days before any scheduled blood work.

How long before I notice a difference?

Hair and nail changes are slow by biology — most people allow at least eight to twelve weeks before assessing results. Consistency matters more than speed here.

QQVerified Buyer

The first adrenal support that made a quick difference.

4 days ago

Gentle on a sensitive stomach, and I feel like myself again. I had tried two other glandulars before this and neither sat right.

MRVerified Buyer

Steadier mornings within a fortnight.

1 week ago

I was sceptical about glandulars, but my mid-afternoon crash has genuinely eased. One capsule with breakfast and I forget about it.

ALVerified Buyer

Subtle, but real.

2 weeks ago

Not a stimulant, which is exactly what I wanted. It took about ten days, then I realised I wasn’t dreading the afternoon any more.

SKVerified Buyer

My clinician recommended it.

3 weeks ago

Bought after a blood panel flagged a flat cortisol curve. Easy to take, no jitters, and the sourcing is refreshingly transparent.

TPVerified Buyer

Recovery feels faster.

1 month ago

Training hard through a stressful stretch and this has helped me bounce back between sessions. Already on my second bottle.

DVVerified Buyer

Does what it says.

1 month ago

No frills, one ingredient, a sensible dose. I appreciate that it is designed to be used for a season rather than forever.
