Dr. Mercola Hair, Skin and Nails – Biotin, Keratin & Hyaluronic Acid – 30 Capsules

Key Benefits of Biotin Supplementation

Biotin, a water-soluble B vitamin, is essential for metabolising fats, carbohydrates and proteins. It supports keratin production, the structural protein that forms the foundation of healthy hair, skin and nails. Many users notice stronger, less brittle nails and improved hair texture with consistent intake. The solubilised keratin in this formula, sourced from premium New Zealand wool, offers a highly absorbable form compared to denatured alternatives. Hyaluronic acid, renowned for its moisture-retaining properties, helps maintain skin hydration, smoothness and elasticity at a cellular level. Together, these ingredients work synergistically to nourish beauty from within and promote a youthful appearance. Dr. Mercola's formula is a premium, non-GMO, gluten-free and soya-free choice for those seeking comprehensive beauty support.

How Much Biotin Should You Take? Recommended Dosage Guide

The recommended dietary allowance (RDA) for biotin in adults is 30 mcg per day, easily met through diet. However, supplements often provide higher doses, ranging from 300 mcg to 10,000 mcg, for targeted support. While no upper limit is established, high doses like 10,000 mcg are generally safe but may not offer extra benefits beyond correcting a deficiency. Dr. Mercola Hair, Skin and Nails delivers a balanced blend of biotin, keratin and hyaluronic acid in a convenient capsule. For best results, follow the serving size on the label and consult a health care professional to determine your individual needs. Note: The specific biotin content per serving is not listed on the label; the formula is designed to support general hair, skin and nail health as part of a holistic approach.

What to Look for in a Biotin Supplement

When selecting a biotin supplement, consider the form, purity and additional ingredients. Dr. Mercola's formula uses high-quality, non-GMO ingredients and is free from gluten, soya and artificial additives. The keratin is solubilised for enhanced absorption, and the hyaluronic acid is low-density for deep hydration. Certifications like non-GMO and gluten-free indicate a commitment to purity. Look for products that list specific ingredient sources and avoid unnecessary fillers. Dr. Mercola also emphasises regenerative practices and informed consent, empowering you to take control of your health.

Possible Side Effects and Interactions

Biotin is generally well tolerated with no significant side effects reported at typical supplement doses. However, high doses may interfere with certain lab tests, such as thyroid function tests. If you are taking anticonvulsant medications or have a history of kidney or liver issues, consult your doctor before starting supplementation. As with any supplement, discontinue uses if you experience any adverse reactions.
