Vitamin B7 Deficiency

A vitamin B7 deficiency( also known as a biotin deficiency) is a condition in which there is not enough vitamin B7 taken in daily to meet the needs of the human body.

When a deficiency occurs, there is a good chance that the individual will experience symptoms that are somewhat mild but still noticeable. However, some people have experienced severe health issues due to a lack of biotin in the body.

Identified in some older health books as vitamin H, biotin or B7 is commonly included in B-complex supplements sold in various retail outlets.

Signs and symptoms of vitamin B7 deficiency

One of first symptoms of vitamin B7 deficiency is a change in the condition of the hair. A person who is not getting enough biotin each day may notice some hair loss.

In addition, the texture and gloss of the hair may change from healthy and shiny to dull and somewhat lifeless.

Various skin conditions can also indicate that a vitamin B7 deficiency is present. Just as the hair begins to dry out, the skin can as well when biotin levels are low.

There is more of a possibility of developing dry, scaly patches of skin on the arms, legs, and in the groin area. If left unchecked, the texture of the skin may become exceedingly rough and easily irritated.

Vitamin B7 works with the other B vitamins in helping to sustain a healthy nervous system. When a vitamin B7 deficiency occurs, it can minimize the ability of other vitamins in the B family to supply the nerves with the nourishment required to function normally. As a result, the lack of biotin can lead to periods of depression that get worse over time, as well as some tingling in the extremities.

Biotin deficiency treatment

Fortunately, all vitamin B7 deficiency symptoms can be treated effectively by using supplements and taking care to eat foods containing a decent amount of biotin. Alternative health professionals often recommend the use of a B-complex supplement if biotin levels are low, since it is easier to keep the ingestion of the vitamin in line with the other members of the B family.

To augment the supplemental vitamin B7 deficiency treatment, adding soybeans, carrots, oats, and raspberries back to the daily diet will help restore a balance of biotin in the body.

In addition, onions, cucumbers, yogurt, and molasses are good sources of this vitamin. Eggs are also a good source when consumed in moderation, but can actually trigger a deficiency if consumed in excess.

Since vitamin B7 is water-soluble and only a small amount is stored in the liver, it is important that the biotin supply is restored each day. Taking steps to eat a balanced diet and supplementing with a good quality B-complex vitamin product will help to prevent the occurrence of this type of deficiency and help keep body and mind healthy.

Generally, people who follow this regimen will notice a difference in mood, hair texture, and skin condition within a couple of weeks.

Biotin deficiency symptoms, causes and treatment

What is biotin?

Biotin is a member of the B-vitamin family (Vitamin B7). The name biotin is taken from the Greek word bios, which means life. Biotin is needed for a lot of body processes that break down fats, proteins, and carbohydrates into fuel you can use. Biotin is also called Vitamin H.

Biotin deficiency causes

Deficiency of biotin has been noted in prolonged intravenous feeding where biotin was omitted.
Biotin deficiency has also been linked with consuming large numbers of egg whites, as egg whites contain a protein which binds to biotin.
Biotin deficiency can result from a genetic lack of biotinidase, an enzyme that releases biotin from small proteins. This lack of biotinidase is a rare hereditary disorder.
Pregnant women may be at risk for borderline biotin deficiency.

Biotin deficiency symptoms

Major biotin deficiency symptoms include hair loss, a dry, scaly rash around the eyes, nose, mouth, and genital area, decreased appetite, nausea and vomiting and failure to thrive in children.

Neurologic symptoms in adults cause depression, lethargy, hallucination, and numbness and tingling of the extremities.
People with hereditary disorders of biotin metabolism resulting in functional biotin deficiency have evidence of impaired immune system function.
Infants deficient in biotin often develop this scaly scalp condition

Sources of Biotin

Adequate intake for biotin has been set at 30 mcg per day for healthy adults.
Biotin is found in a wide variety of foods. Good sources of biotin are liver, oatmeal, eggs, peanut butter, milk, salmon, clams, bananas.
Anticonvulsant medications may lower biotin levels. Additionally, antibiotics may lower the production of biotin because some antibiotics kill bacteria in the colon.

Biotin is not known to be toxic.
Diagnosing a biotin deficiency can be difficult, due to the rarity of this condition and the rather vague symptoms of biotin deficiency.

Vitamin B7 or Biotin deficiency

Vitamin B7 or Biotin like any good member of the vitamin B complex works closely with other B’s, especially folic acid, pantothenic acid, and cobalamin. Main function of biotin is energy metabolism.

Biotin involved in the synthesis of fat, glycogen, and amino acids and enzyme reactions. It required for DNA replication and is important for healthy hair and nails.

Biotin for hair and nails

Many hair amd nail care products now contain biotin, claiming that it helps make healthy hair and prevent balding and graying. It’s true that you need biotin for healthy hair and that severe biotin deficiency causes hair loss.

The biotin in a shampoo or conditioner isn’t likely to do much for you, though.

Hair lost from biotin deficiency grows back when you fix the problem, but hair lost from natural balding is gone for good.

Biotin is made by the bacteria living in healthy large intestines. The wall of the large intestine has a specialized process for the uptake of biotin. This may be one reason why biotin deficiency is so rare.

Causes of Biotin deficiency

Deficiency of biotin has been noted in prolonged intravenous feeding where biotin was omitted. The only other example of biotin deficiency is from long-term consumption of raw egg whites.

Biotin can bind to avadin, a protein found in egg whites. Cooking inactivates this bond, so cooked egg whites do not bind biotin.

Deficiency can result from a genetic lack of biotinidase, an enzyme that releases biotin from small proteins. This lack of biotinidase is a rare hereditary disorder.

Pregnant women may be at risk for borderline biotin deficiency. The developing fetus requires more biotin than is sometimes available.

Biotin deficiency symptoms include hair loss; scaly red rash around the eyes, nose, mouth, and genital area; depression; lethargy; hallucination; numbness and tingling of the extremities; and impaired glucose utilization and immune system function.

Food sources of Biotin

Biotin is found in many foods, but the best sources are beef liver and brewer’s yeast. Egg yolks, nuts, and whole grains are also good sources.
