Which Brand Of Biotin Supplement Should You Buy?

**Spoiler** if you really can't be bothered to read all our research just click here to go to the number 1 brand on our list.

Also known as Vitamin B7 and sometimes as Vitamin H or coenzyme R, biotin is an increasingly popular nutrient that’s common in whole foods, particularly animal products, nuts, seeds, and avocado.

Recently consumers have been taking extra biotin as a supplement because of the beauty benefits with hair growth, nail strength, and skin health. With countless companies producing their contenders for best biotin supplement, it's very tough to distinguish between the legitimate brands and the snake oil merchants.

Manufacturers are already tapping up celebrity endorsers to promote their biotin products and the real truth is most of these endorsers do not know what is in the product and nor do they care.

Brands are investing an average of £640 million in advertisements for nutritional supplements and giving away products to consumers in exchange for a positive amazon review.

So with all this deception, which among them are actually safe and effective to use?

Here at Supplement Informer, we understand how tough and overwhelming it can be to study, research, and pick the best biotin brand supplement.

Thats why we've done all the hard work for you.

We searched for the top-selling biotin supplement brands ono the market and purchased all of them so we could personally test them and consult with our team of beauty experts who provided some much needed insight on the quality of all the different biotin supplements on the market.

But firstly some insight on why you might need a biotin supplement.

Why Do We Need To Take Biotin Supplements?

The biotin market is estimated to reach £5.3 billion by 2026 for one simple reason:

People who eat a healthy diet can get adequate amounts of biotin from the food they ingest. However, there are several groups of people who are more likely to be deficient in this vitamin. These groups include:

Biotin deficiency can cause a host of symptoms such as…

Supplementing with biotin can help maintain healthy levels in the body, regardless of your age: keeping your hair, skin, and nails healthy and youthful. But there’s more to biotin than just looking good. Biotin is also critical to achieving healthy psychological function and maintaining good energy throughout the day. With supplementation, no matter how bad a food day you’ve had, you can relax in the knowledge you’ve got this important vitamin covered!

But here’s the catch.

BEWARE: Not All Biotin Is Equal

We're going to expose a key peice of information that most biotin brands keep a secret.

Biotin is water-soluble, meaning, it can easily dissolve in water. Therefore, excess biotin isn’t stored in your body; it actually flushes right out of you when you urinate.

Biotin needs to be drip fed into the system over an extended period of time. Typically this is achieved through a healthy diet, but this isn’t always possible. Eating on the go and missing meals in our busy lives makes this virtually impossible.

Here’s What To Look For In Biotin Products
And What You Must Avoid At All Costs.

Must Haves

  • Biotin Potency:

    Optimal dosing of 10,000µg biotin per day for superior results.

  • Biotin Formats:

    Among all formats, from tablet, soft gel, gummy, and liquid: capsules are highly recommended.

  • Biotin capsule size:

    Small or medium-sized so it’s easy to swallow and digest

  • Manufacturing Standards:

    Food supplement safety and product quality are often overlooked. Look for products made to ‘GMP’ (Good Manufacturing Practice) – the gold standard. Made in the UK should also provide consumer reassurance due to strict regulations in place.

Must Avoid

  • Sugar Content:

    Look out for chewable tablets, powder blends, liquids and gummies which typically contain sugars to enhance flavour. Sugars are generally proinflammatory.

  • Labels without Full Ingredient Disclosure:

    Transparency is key. Know what you are consuming, so pick from a reputable brand that hides nothing.

  • Artificial Ingredients:

    Artificial sweeteners, colours, preservatives, and flavourings and are known to negatively affect gut health.

  • Environmentally-Unfriendly Packaging:

    Look after the planet and avoid non-recyclable packaging.

The Bottom Line

What We Loved

Rock & Roses is the only brand on the market that uses an Excellent Dose of Biotin whilst incorporating unique Delayed Release Capsule Technology.

Rock & Roses is the only company offering a No-questions-asked 90-day money-back guarantee.

Plus, they’ve thoughtfully engineered the vitamins to provide the most optimal results. Here are a couple of benefits over other brands:

  1. Delayed Biotin Release. We found that other, high dose, rapidly absorbed formulas run the risk of passing most biotin through the urine and poses the question, are they worth the money? Biotin 10,000µg Delayed Release was the most effective over the other brands we reviewed.
  2. Less stomach upsets.Unlike other brands, Biotin 10,000µg Delayed Release causes less stomach upsets and less biotin wastage. This may be attributable to their ‘acid-resistant’ capsule technology, delivering biotin safely to the gut for superior absorption.
  3. Transparent ingredients.Overall, Rock & Roses is the only brand that’s completely transparent about their ingredients, and therefore the only brand we are certain it’s safe for you to consume.

 

There’s just one small thing…
