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.

Benefits of High Quality Biotin

Biotin Supplements can be a very effective and inexpensive way to boost your heart health. By choosing the right supplement, you may see an improvement from just 3-4 weeks.

  • Promotes Optimal Immune Function

  • Supports Energy Production

  • Supports Optimal Metabolism

  • Maintains Healthy Hair & Nails

  • Boosts Cognitive Function

  • May Improve Skin Appearance

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.

Pros

Cons

  • Low 5000ug Dosage
  • No Additional Ingredients
  • No Money Back Guarantee

The Bottom Line

Solgar is a trusted brand in the supplement space and their Biotin product is quite popular, but it has a few shortcomings.

Firstly, it contains a relatively low dose at just 5000ug, which is half of the recommended dose and certainly one of the lower doses on the market.

In addition, it fails to include any additional ingredients such as Zinc or Selenium, which makes it less effective overall and less value for money.

Solgar accepts returns but only within 14 days of ordering and only for unopened packaging.*

Pros

  • 10,000iu of Biotin
  • GMO Free & Vegan Friendly

Cons

  • No Additional Ingredients
  • No Money Back Guarantee

The Bottom Line

This pure Biotin product by Natural Answers is a vegan friendly, GMO free capsule with 10,000iu of Biotin. While it is of reasonably good dosage, we do recommend 11,000-12,000iu for best effects.

This product does not contain any additional ingredients, such as Selenium or Zinc, making it less value for money despite the reasonable price.

Natural Answers does not provide any money back guarantee and requires all returns to be in unopened packaging.*

Cons

  • Low 2,500IU Dosage
  • Does Not Include Zinc or Selenium
  • No Money Back Guarantee

The Bottom Line

Vitaldin’s Biotin product is in gummy form, which may be useful for those who have difficulty taking capsules. However, this change in form comes with certain trade offs.

Firstly, it contains a very low dosage of just 2,500iu worth of Biotin. This is a quarter of the recommended dose.

On the plus side, it does contain Collagen which is highly beneficial for skin and hair health. However, 100mg of Collagen is not sufficient to see material improvements based on studies.*

Pros

  • Cheap
  • Vegan Friendly

Cons

  • Very Low Potency of 1000ug
  • No Additional Ingredients
  • No Money Back Guarantee

The Bottom Line

H&B’s Biotin supplement is one of the most popular formulas in the UK, largely due to the brand’s reputation. In terms of this specific formula, it contains a very weak dose of just 1000ug of Biotin.

In addition, it contains no additional ingredients such as Zinc, Selenium or Copper.

As a trusted UK brand, this may be a good option for those looking for something on the cheaper end, but unfortunately that will come at the expense of potency and quality.*
