What Is Biotin?

Did you know? Biotin is so essential, that you can’t live without it. In fact, is is one of the most important vitamins and helps with our metabolism, energy production as well as keeping up healthy hair and nails.

A good quality Biotin supplement could greatly help with fatigue, weight loss and in boosting your hair, nail and immune health. However, not all Biotin supplements are equal and choosing the wrong kind can be an ineffective, costly mistake.

We’ve listed below the benefits, what to look for and compared 5 leading products.

What To Look For?

Biotin Supplements are NOT all the same. It’s important to choose quality, proven formulas from trusted brands to see real benefits.

At Least 11,000ug of Biotin Per Serving Choose a supplement that includes at least 11,000ug, which is a good strength dose and is frequently cited as the recommended dose in clinical studies.
Additional Ingredients (Zinc + Selenium) It is important to look for a formula which includes beneficial co-ingredients, such as Zinc or Selenium. These two ingredients can work to boost the overall effects on your immunity, metabolism as well as hair and nail health.
Money-Back Guarantee It is important to buy from brands that stand behind their product. Without a guarantee, you could lose your money and end up with an ineffective product. It is recommended to look for brands that offer a 30-60 day money back guarantee.

What Should I Avoid?

Poor Formulations & Doses It is recommended to stay away from products which do not contain at least 11,000ug of Biotin. In addition, keep an eye out for poor formulations which are either not made in the UK or do not include additional, supporting ingredients.
Artificial Reviews Watch out for product listings on Amazon and other marketplaces with fake reviews. When it comes to supplements, you are safer buying directly from trusted brands who are based in the UK. Buying from marketplaces or middle men companies gives you no guarantee when things go wrong.
