This vitamin is found in foods contained in the daily diet - typically in small amounts; it is an important component of enzymes which are responsible for breaking down certain substances within the body which include fats and carbohydrates.

It it used to treating biotin deficiency that is associated with various health ailments, as well as natural conditions such as pregnancy. It is used by some individuals in oral form for treating hair loss, brittle nails, seborrheic dermatitis, diabetes and mild-stage depression.

Where self-treatment with this vitamin is involved, it is often ineffective. For example, treating skin rash is ineffective. Treating  diabetes might assist in lowering blood sugar levels in some individuals when combined with chromium and it may serve to reduced pain associated with nerves in the diabetic.

However, your most effective treatment for all of the above health situations should be placed in the hands of the qualified physician as self-treatment often leads to worsening most health conditions rather than bettering them.

Recommended Daily Allowance (RDA) for Vitamin Biotin

At this point, there is no recommended RDA that has been established for biotin. Adequate intakes are as follows:



0 to 12 months


1 to 3


4 to 8


9 to 13


14 to 18


Over 18 and Pregnant Women


Lactating Women


Best Food Sources for Biotin

Beans, bran cereals, bread, brown rice, oatmeal, molasses, wheat germ, peas, mackerel, herring, avocado, currants, egg yolk, nuts, cauliflower, liver, kidney and fish. Most fruits and meats are very poor food sources for this Vitamin.

The nutritional arena is also incomplete at this time as researchers continue to learn more about this B Vitamin. There is very little known about the biotin content in foods. So little is known about this vital B Vitamin that the required recommended amounts must be mathematically derived based on the levels of biotin found within mother's (human) milk.  But we do know that it is a necessary element for optimum health.

Deficiency Signs & Symptoms of Biotin

1. Hair Loss
2. Rash & Skin Disorders.
There may be a red area or rash around the nose area.
3. Stunted or Delayed Growth in Children
4. Delayed Development in Children
5. Convulsions, Seizures
6. Neurological Issues, nervous system related from mild to severe.
7. Loss of muscle tone. Coordination issues.
8. Coma
9. Death, if left untreated.

Deficiency is a Rare Situation

Let us note that deficiency in this B-Vitamin is very rare. So many of the foods that we eat throughout the day contain biotin, so unless the diet is deficient, we tend to obtain adequate amounts in a normal, well-rounded healthy diet built on the Food Pyramid.

1. A poor diet. If Jane loves hard candy and has nothing but candy all day, then she is putting her body at risk for ill health.

2. A genetic defects in infants (very rare and treatable in early stages).

3. Consumption of a dozen or more raw egg whites over a period of time. Eggs contain a protein called avidin which prevents biotin being absorbed by the body as avidin binds with biotin. Cooked eggs are an excellent source for this vitamin as avidin is denatured when it hits the heat. If you consume numerous raw egg whites per day, speak with your doctor about any concerns. Although it would take an excessive amount of raw whites per day for a deficiency to occur, it is a possible scenario.

4. A few anticonvulsant drugs can increase deficiency risks as they break down this B-Vitamin.

5. Individuals who are on kidney dialysis may require more biotin.

6. Health studies suggest that tobacco may contribute to biotin deficiency.

Toxicity Signs & Symptoms of Biotin

None known. There is no UL (upper limit) set for biotin at this date as high doses do not present toxicity issues.

How Biotin is Used in the Body & Therapeutic Benefits Including History & Discovery

Energy production, synthesizing fats, nervous system support. May assist in stabilizing blood sugar levels when paired with chromium but should only be supplemented upon the advice of a qualified physician.

It's difficult to believe, but the age of modern medicine is actually still in its infancy. Take the discovery of biotin; it has been less than 100 years since its discovery by researchers. Back in the year 1924 - the year of its discovery, the researches believed they had discovered three growth factors: Bios II, Vitamin H, Coenzyme R. They rapidly learned that what they had discovered was only one substance - the B Vitamin Biotin.

If medicine has advanced this far in this short amount of time, the future may hold the key to unlocking the mysteries for many of our detrimental diseases. Cures for all types of cancer may surface, as well as cures for so many other devastating illnesses. So on that note - here's to a healthier future for all!

The Body Functions

Biotin is a member of the Vitamin B family and acts as a coenzyme if numerous reactions that occur within the human body. Think of it as link within a chain. It is required in the chain to spawn certain functions, and without it, things can quickly go into a negative direction.

Here is a short list of how it assists our body throughout the day via reactions:

1. Amino Acid Metabolism
2. Converts Amino Acids to Glucose through a process called gluconeogenesis.
3. Fatty Acid Synthesis.
4. Release of Energy From Fatty Acids.
5. DNA Synthesis.

Without Biotin at work within the human body, certain areas and functions woulld be impacted so severely they they could not perform - or they would perform poorly. Digestion and energy levels would be drastically effected.
