In today's health-conscious world, people are always searching for the best health supplements they can get. It is not surprising that there is a trend of searching for the best biotin supplement on the market for the current year. This article focuses on these so-called super vitamins and the benefits they offer for a healthier body.


Facts About Biotin

Biotin, also known as Vitamin B7 or Vitamin H, comes from the Greek word "biotos" which means "life." It is a water-soluble vitamin and can be derived from a healthy balanced diet. Biotin is needed for the optimal function of the enzymes called carboxylases, which in turn, are essential for the production of glucose and fatty acids. Food is broken down into sugar, and the sugar is then converted to energy for physiological function. Biotin transforms the fat, proteins, and carbohydrates into the calories the body needs.

Dietary Sources of Biotin

Many foods can be sources of biotin. These may be in the form of:

Uses of Biotin Supplements

Biotin supplements are used to manage the symptoms related to its deficiency when a person’s diet isn’t as balanced as it should be. These are some benefits provided by the vitamins.

#1. Biotin aids in the management of onychoschizia, also known as a brittle nail. In one study, nail thickness improved in all participants by 25% with the 2.5 mg intake of biotin daily for 6 to 15 months.

#2. Since biotin deficiency is linked to thinning hair and hair loss, supplementing with the vitamin may be beneficial in promoting hair regrowth.

#3. It is an essential nutrient during pregnancy that promotes fetal growth. It is estimated that 50% of pregnant women might experience a mild form of biotin deficiency.

#4. Biotin, in combination with chromium, may assist in lowering blood sugar levels in people with type 2 diabetes.

#5. Biotin aids in fat metabolism and may also help prevent dry skin. Due to the vitamin’s healing and moisturizing characteristics, massage oils now often contain biotin.

#6. Biotin is perceived to be a major factor in the production of myelin, the protective covering of nerve fibers in the brain, spinal nerve, and eyes. Improved biotin production has been shown to improve progressive multiple sclerosis as shown by some clinical studies.

#7. There is also evidence that biotin can alleviate the symptoms of fatigue and depression.

While this list may not be all-inclusive, biotin is also used to manage seborrheic dermatitis (cradle cap) in infants. As with other medications, consult your physician when planning to give this supplement to children.

Recommended Daily Allowance

There is currently no recommended daily allowance (RDA) for biotin, but some studies, the suggested levels of intake in micrograms (mcg) is:


Recommended Daily

Birth to 3 years

10 to 12 mcg

4 to 6 years

25 mcg

7 to 10 years

30 mcg

11 years to adults

30 to 100 mcg

Other considerations are:

During pregnancy: at least 30 mcg

During breastfeeding: at least 35 mcg

Causes of Biotin Deficiency

The incidence of biotin deficiency is small, but it is better to know the possible causes to prevent any deficiency better.

  • Prolonged intake of antibiotics that destroys the good bacteria in the gut.
  • Anticonvulsants such as carbamazepine and phenobarbital.
  • Intestinal malabsorption diseases such as celiac disease or Crohn’s disease.
  • Intravenous feeding since the actual sources of biotin in food is usually missing.
  • Long-term dieting since this restricts the absorption of biotin from natural foods.
  • Biotinidase deficiency which prevents the body from reusing biotin.
  • Cigarette smoking since it diminishes the absorption of nutrients.
  • Excessive eating of raw egg whites since they hinder biotin absorption.
  • Genetic disorders such as holocarboxylase synthetase deficiency and phenylketonuria.

Side Effects of Biotin Supplements

Not much is associated with biotin toxicity although taking them within the suggested limits is the safest route. Furthermore, biotin supplements are safe to take during pregnancy and while breastfeeding. Nonetheless, you should always inform your physician about any supplements you are taking and always consult a doctor when planning to give biotin to a child.

Another consideration is the amount of biotin intake that will interfere with the results of some diagnostic tests such as biotin-streptavidin technology for measuring thyroid and other hormone levels. Supplementing biotin may interfere with the assays used in the tests and may provide false positive or false negative findings.

A minor side effect among some users is the increase in the incidents of acne and rashes when taking biotin. When taking biotin supplements, the amount of biotin in the gut far outweighs the quantity of vitamin B5. Thus, this may lead to a vitamin B5 deficiency in some cases since this vitamin regulates the barrier function of the surface layer of the skin. In simpler terms, a vitamin deficiency of B5 could possibly lead to acne flares.

Biotin Deficiency Persistence

If biotin deficiency is not addressed, the development of the so-called biotin deficiency face may exist. Clinical presentation of this is a characteristic facial rash plus an unusual and uneven facial fat distribution. Persistent biotin deficiency might also result in a compromised immune system and increased susceptibility to fungal and bacterial infections. Moreover, severe biotin deficiency during pregnancy might cause congenital anomalies such as cleft palate and lip.

Not Only for Humans

Biotin is not only taken by people for better health but also given to animals such as dogs and horses. The nutritional supplement promotes and maintains the growth of healthy hooves and coats. Horses might benefit from supplementation to address dry, brittle hooves, and cracked feet as well as chronic, recurrent laminitis.

Similarly, dogs can benefit from biotin supplementation especially those with skin and fur conditions. A quality diet will provide sufficient levels of biotin for dogs but in some cases, there may be a biotin deficiency, and a canine-formulated supplement such as Bio Coat can be administered.

Some Reasons Why Biotin May Not Be Effective

Given the benefits of biotin, there are some instances where biotin supplements may not work as well as desired. These instances are usually the result of using an inferior product.

  • Inadequate amount of biotin in the supplement – there should be at least 5,000 mcg to 10,000 mcg to make the supplement effective. Efficacy might be compromised with the lesser amount indicated.
  • Allergies to other ingredients – although the main active ingredient is biotin, there are other ingredients in the supplement that are needed to produce the synergistic effect. Components that may cause allergies in certain individuals are soy, gluten, and fish to name a few.
  • Quality of the product – if the price is too low, then the quality is likely to have been compromised.

Best Rated Biotin Supplements on the Market

To help you select the best biotin supplement, I did research, and my investigative effort led to the short list of the following supplement brands. The criteria used for selecting these brands was based on the following:

  • Rating
  • Quality
  • Price

With these reviews, I aim to provide an overview of the different products, but the final choice will still be yours to take based on personal preferences or actual testimonials. If you plan to take biotin supplements, not all supplements are created equally. It is best to purchase high-quality supplements made from organic or real food sources. Avoid those with fillers and toxins.
