Biotin Hair Growth Supplement 10000mcg 180 Vegan Tablets

An Important Note on This Dose Before You Start

This product delivers 10,000mcg of D-biotin per 2-tablet serving, alongside zinc citrate and selenium (as sodium selenite). As covered in more detail in our complete biotin guide, biotin has an established, EU-authorised role in the maintenance of normal hair and skin — supplementation helps most reliably where a genuine deficiency exists, and true biotin deficiency is uncommon in people eating a varied diet, regardless of the dose taken.

Given this dose specifically, one safety point matters more than usual and is missing entirely from this product’s description: high-dose biotin can interfere with certain thyroid and cardiac blood test results, causing falsely abnormal readings. If you take this supplement regularly and have blood tests scheduled, tell your GP or the laboratory beforehand — this is a genuine, documented interaction, not a minor footnote, and becomes more relevant the higher the dose.

Zinc has a genuine, EU-authorised role in normal fertility and reproductive function, alongside immune function and protein synthesis — accurate as stated. Selenium is a genuine antioxidant with an established role in normal hair and nail maintenance; the sodium selenite form used here is well-absorbed, though it’s worth knowing the UK safe upper limit for selenium is 450mcg daily from all sources combined — this product doesn’t specify its selenium content per serving, so it’s worth checking against this limit, particularly if you take a multivitamin or other selenium-containing supplement.

Biotin is generally well tolerated, with mild digestive changes possible when starting. Vegan, gluten-free (produced in a facility that handles dairy). Take two tablets daily with a full glass of water. Not suitable for under-18s. Speak to your GP before starting if you take regular medication, have thyroid-related blood tests scheduled, are pregnant, or breastfeeding.
