10 Best Biotin Supplements Reviewed & Fully Compared


Biotin is a water-soluble B vitamin that is necessary for life.  Biotin turns the carbohydrates and fats from your diet into energy ready for your body’s use.  Biotin occurs naturally in many foods: meat and fish, some veggies, soybeans, egg yolks, yeast, mushrooms, and a host of other foods all contain naturally occurring biotin. 

Since biotin is in so many different foods you may find it strange that anyone would have a deficiency in it. However, there certain events can cause our diets to be so off-kilter that supplementation is necessary. Recovering from surgery, or having a prolonged illness that affects how you eat are just two examples.

Choosing the right biotin supplement for you really depends on your own personal needs.  You can find biotin in a variety of forms, dissolvables, liquid, gummies, soft gels, capsules, or pills and it can be a standalone vitamin or be formulated as part of a vitamin B complex.  If you are using supplements to help care for an illness or health-related problem, you are likely to need a higher dose of the pure supplement itself over a formulation mix. For other purposes, not health or illness related, the benefit bests come through the formulation with a B complex.  If you are unsure of what specifically will benefit you the most, talk to your health care provider and ask questions. They are going to be your best bet for accurate and personalized information to help you make the best choice possible. The good news is because biotin is water soluble it is very difficult, if at all possible to overdose or have any side effects from toxicity through ingesting too much.  If there is excess it is simply excreted through your urine.

Criteria Used in Choosing the Best Biotin Supplements



The reality is that most healthy adults don’t need too much biotin.  It is readily available in so many of the foods we eat that most of us to meet our needs on a daily basis automatically.  The National Academy of Medicine however, advises that 30 mcg per day is needed for the average adult while breastfeeding women can use up to 35 mcg.  Biotin isn’t readily absorbed through the skin so oral supplementation is the way to increas your levels when needed. People have mostly found that pills formulated with either 5 mg or 10,000 mcg are the most potent and provide the best results.  

It is important for the companies and manufacturers of supplements to take testing and quality assurance seriously and spend the right amount of time ensuring that their products are correctly measured and advertised. You want to be confident in what you put into your body, so if you take a supplement, knowing that what is on the label is what you are getting in the pill matters. The companies who make the supplements on our list have put a high level of testing and assurances into all the products they make.


Quality ingredients that aren’t bogged down with artificial ingredients and junk additives are the best. Most people are looking for the standalone vitamin, and they don’t want any other ingredients in their pills.  However, there are some pills that will have a couple extras, for instance, flavored pills that dissolve may have some natural flavoring to add that feature. Sports Research formulates their softgel with organic virgin coconut oil.  Sometimes biotin is the main ingredient in a specifically formulated mix of vitamins and minerals because it is a component of a larger multivitamin aimed at supporting a specific health need. BariMELTS is an example of this. It is specifically formulated with biotin as the main ingredient for those who are recovering from weight loss surgery.


If a supplement says it is going to do something and it doesn’t, it’s not worth spending the money on or taking.  Every product we reviewed had a high rating for being effective. Some worked well all around, and others showed more prominent effectiveness in one or two specific treatments.  While the science is still pending regarding a direct connection between healthy hair, skin, and nails, the supplements provided in this review have high ratings because the people that used them saw improvements with the use of the supplement.  So, personal accounts show that they do in fact, have effectiveness for hair, skin, and nails.

Biotin is a necessary vitamin to support normal body functioning.  There may be some science behind helping diabetics controling their glucose with biotin and it could be used by some pregnant women should they have a deficiency.  It is always recommended, though, that to improve overall health eating a balanced diet with more natural foods which is full of fruits and veggies, along with consistent daily exercise is the best way to ensure that you are the healthiest you can be.

Ease of use

As with any supplement, people will only be consistent with medications and vitamins if they are easy to take.  Some people have no problem swallowing tons of pills at once and large pills go easily down the hatch. Others can barely swallow a small pill.  Many of the products we reviewed above were very easy to take. Some were quickly dissolved on the tongue, others were very small pills, and there were softgels that could be smoothly taken down.

Other Important Factors to Consider

There are some people who have specific health conditions that must take the time to read carefully the labels of the supplements they take before they take them.  Diabetics, for instance, are going to want to make sure they aren’t adding extra sugars to their diets, and since some pills can be formulated with sugar it is important for these people to know ahead of time.  Other products could have wheat or dairy and for those people allergic to these foods, this is important to know. Vegetarians and vegans can benefit from finding pills that are formulated as vegan or vegetarian, they are out there and if you read the label you can be sure to find one that doesn’t have any ingredients related to animals at all.


Frequently Asked Questions

Q:  What are some symptoms of biotin deficiency?

If you have dermatitis, increased fatigue, suffer from depression, have tingling or numb feelings in your arms and legs or if you suffer from massive hair loss, you may have a need for additional biotin in your diet.  Go to your doctor and have them check you out because self-diagnosis is difficult to do. The symptoms that B7 deficiency may easily be related to a separate health issue which needs professional diagnosis and treatment.

Q:  Can biotin really help with my hair growth?

When it comes to ensuring your skin is healthy and supple, biotin has been found to promote growth.  Don’t waste your money on shampoos containing biotin or lotions because it is not easily absorbed by the skin and hair.  It basically has no effect  when taken this way. It is best used by supplementing orally. While biotin is not the only element that is needed for faster and thicker hair growth, it certainly is one of the factors promoting healthier hair.

Q:  Can biotin help nails?

There have been studies that showed biotin, also known as vitamin H, can affect the thickness of finger and toenails. It is generally believed that vitamin H plays a strong role in keeping nails and hair healthy.   That being said, there are a whole host of reasons why you may have brittle nails including exceptional dryness or exposure to various nail polishes.

Q:  What causes hair loss?

There are a whole host of reasons why you may be experiencing hair loss.  Everyone loses hair each day, but at a rate that is natural, when it becomes intense you have a problem.  An underactive thyroid shows up in one of the first symptoms being hair loss. An underactive thyroid means your metabolism becomes lethargic and when that happens your hair loss rapidly speeds up.
