Source Naturals Biotin 10,000 mcg - Hair, Skin & Nail Support - 120 Tablets

How Much Biotin Do You Need?

Discover Source Naturals Biotin, — Biotin supplements come in a wide range of doses, from 300 mcg to 10,000 mcg. The recommended dietary allowance for adults is only 30 mcg per day, but higher doses—like the 10,000 mcg found in this product—are commonly used by those aiming to support hair, skin and nail health. However, scientific evidence for benefits at such high doses is limited; most studies show improvements in individuals who were deficient. The usual serving is one tablet daily, ideally with a meal to aid absorption. It is important to follow dosage instructions and not exceed the recommended intake unless advised by your health care professional. Consistency is key, and because biotin is water-soluble, any excess is excreted in urine.

The Benefits of Biotin Supplementation

Biotin is widely known for its contribution to the maintenance of normal hair, skin and nails. Many users report stronger, less brittle nails and improved hair texture with consistent uses, although individual results vary. Biotin also contributes to normal energy-yielding metabolism, helping you feel energised throughout the day. This high-potency formula delivers 10,000 mcg per tablet—far above the RDA—making it a popular choice for those targeting hair and nail concerns. Always consult a health care professional before starting any new supplement.

This product is a food supplement and should not be used as a substitute for a varied, balanced diet and a healthy lifestyle.

Are There Any Side Effects or Interactions?

Biotin is generally well tolerated and considered safe, even at high doses. However, some individuals may experience mild digestive upset or skin reactions. Toxicity is rare because biotin is water-soluble. Notably, high biotin intake can interfere with certain laboratory tests, including thyroid function tests and troponin assays, leading to inaccurate results. If you are taking any medications, especially anticonvulsants, or have a medical condition, consult your doctor before uses. Always inform your health care provider of all supplements you take to avoid potential interactions.
