Biotin, also known as vitamin B7, contributes to the normal maintenance of hair and skin - an EU-authorised nutrient function that makes it one of the most consistently sought food supplements in Irish pharmacies. The range at Ronaghan's Pharmacy includes biotin-only tablets across a variety of daily strengths, from standard 1,000 mcg formats to higher-strength 5,000 mcg and 10,000 mcg options, alongside combination supplements that pair biotin with complementary nutrients such as zinc, selenium, and marine collagen to address hair, skin, and nail concerns together. Selecting the right format depends on your starting point and how you prefer to supplement. A standalone biotin tablet is straightforward if you already take a broad-spectrum multivitamin and simply want to top up your B7 intake. A dedicated hair, skin, and nails formula is worth considering if you prefer a single daily product covering several nutrients at once. As with all food supplements, dosage guidance on the label should be followed, and the product information leaflet should always be read before use. If you are taking any prescribed medicines or managing an existing health condition, speaking with our pharmacist before starting a supplement is advisable. All products stocked here are available to order online for delivery across Ireland or to collect in store. For a broader view of nutritional supplements, the Vitamins & Supplements category carries the full range stocked at Ronaghan's Pharmacy.If you would prefer broad daily coverage, the multivitamins range combines biotin with a full spectrum of vitamins and minerals.
