Biotin (Vitamin B7)

Biotin Benefits

Biotin is also known as Vitamin B7 or Vitamin H and is classified as a water-soluble vitamin. It occurs in a wide variety of foods such as egg yolk, liver and some cereals. The vitamin is also synthesized by bacteria found in the human gut. It is considered readily available and, therefore, Biotin deficiency rarely occurs unless for individuals who are severely malnourished, and sometimes late on in pregnancy. There are also intestinal conditions that can make Biotin unavailable for use by inhibiting its absorption in the digestive tract.

Active Components in Biotin

Biotin is a heterocyclic compound that consists of an Imidazole ring that is joined to a Tetrahydrothiophene ring. Tetrahydrothiophene possesses a Valeric Acid side chain. There are eight theoretically possible Biotin stereoisomers. From amongst the eight, only the D-(+)-Biotin stereoisomer is found in nature. It is known as an enzyme cofactor as it binds to and activates the five carboxylase enzymes found in humans.

Effects of Biotin Deficiency

As mentioned, Biotin acts as a coenzyme in our bodies, supporting the function of the carboxylase enzymes. Since carboxylase enzymes are involved in gluconeogenesis, amino acid metabolism and fatty acid synthesis, Biotin deficiency affects energy metabolism and other physiological processes in the body. Biotin deficiency also compromises the immune system and reduces the synthesis of collagen tissue. Collagen tissue is known for its role in skin elasticity among other functions. Biotin deficiency, therefore, is associated with dermatological conditions such as Psoriasis, seborrheic Eczema, Neuritis and the occurrence of opportunistic infections.

Recent reports indicate that Biotin levels in pregnant women seem to decrease as pregnancy progresses, hence, Biotin deficiency can be found in heavily pregnant women. Biotin deficiency in pregnant women can affect foetal development, as can malnutrition in general.

Symptoms of Biotin Deficiency

Biotin deficiency in both children and adults manifests in various forms that include:

· Hair loss

· Dry and scaly skin

· Scaly rashes around the mouth and the eyes

· Depression

· Fatigue

· Brittle nails

Infants and Biotin

In most cases, children born with milk allergies or those who can’t be breastfed, are usually fed with special therapeutic milk. Most of the therapeutic milk formulations contain tiny amounts of Biotin and others don’t contain any Biotin at all. This means that infants feeding on these formulas don’t get the required amount and may develop Biotin deficiency.

The digestive system of the infants is also immature and may not have developed the bacteria necessary to synthesise Biotin. It has been found that the serum Biotin levels for children with milk allergies are usually half that of the normal infants. Biotin deficiency in children is associated with reduced skin formation resulting in skin that is susceptible to external stimuli. This explains why some children are more vulnerable to diaper rashes than others.

Diabetes and Biotin

Palmoplantar pustular osteoarthropathy and palmoplantar pustulosis are two skin conditions characterized by pustules and rashes on the palms and soles of the feet. According to research, 60% of the individuals suffering from these conditions were diagnosed with diabetes. Increased oral administration of Biotin not only eliminated the rashes and pustules, it also lowered blood sugar significantly.

Biotin as a Supplement

In Europe and the USA, Biotin supplements are available in the form of capsules or tablets and the product has gained a lot of popularity over the years. Some other countries are yet to approve the use of Biotin as a food supplement. Most of these countries have denied approval not because of its toxicity but because of doubts about its importance as a supplement.

The recommended dietary intake of Biotin for infants and children is between 10 to 30 (mcg) while that for adults are between 30 to 100 (mcg). There is no maximum amount set for daily Biotin intake since studies show no side effects for variations of up to 100 (mcg).

Biotin warnings and side effects

Biotin has been classified as a safe and non-toxic vitamin that can be used by any group of individuals. No side effect has been associated with biotin even at higher doses. However, just like any other supplement, it is advisable to consult with your doctor before you start on any supplement especially when you:

· Have been in a long-term treatment with antibiotics

· Smoke cigarettes

· Take medication for seizures

· On dialysis

· Eat more than two raw egg whites

Vitamin B7 – 

The B might stand for the buzz of energy you get when you supplement with Vitamin B. In fact, Vitamin B is not just one single vitamin; it is a family of vitamins, the functionality of each differing with effects ranging from fat burning to mood enhancement. Working with both the brain and the body, there are many benefits to having a sufficient supply of B Vitamins.

B vitamins enable your brain to function better. Vitamin B2 can help migraine sufferers while B6 works with the brain’s neurotransmitters, particularly those that release serotonin. This can enhance your mood and relieve symptoms of premenstrual syndrome. Inositol also has mood-altering capabilities said to reduce depression and anxiety. Vitamin B12 and Choline may also help you reduce brain fogginess and improve memory.

Body Healing

B vitamins also speed up healing. B3 is used to increase a person’s energy to help with DNA repair and bodily healing. Pantothenic Acid works similarly to B3 but is more involved with actual wound healing. Biotin, when used in combination with chromium, shows promise to help blood-sugar control. The B vitamins have so many uses that taking a supplement can really improve your overall health.

B Vitamins Explained

Most of the B vitamins are recognized by their numbers: B1, B2, B3, B6, B9, and B12. Others have names that people may also recognize, namely: Biotin, Choline, Inositol, Pantothenic Acid, and Para-Amino Benzoic Acid (PABA). B vitamins work in conjunction with each other but also have unique benefits on their own. Folic acid, otherwise known as B9, is famous for preventing birth defects in pregnant women. Less well known is the fact that it is also useful for preventing cancer and lowering the risk of heart disease.

The B vitamins are actually a group of eight water-soluble vitamins that often coexist in the same foods. When referring to all eight vitamins at once, it is known as the vitamin B complex. Each B vitamin plays a distinct role in metabolism and energy production. Eating a well-balanced diet containing whole grain foods, meat, dairy, and vegetables are the best way to achieve a healthy balance of B vitamins. Oral Supplements are only partially absorbed but are sometimes medically necessary when absorption problems or malnutrition occur.

Thiamine (Vitamin B1)

Thiamine can be found in cereal, meat, bread, rice, nuts, yeast, and corn. It plays a vital role in metabolism, nerve function, and generation of energy from carbohydrates. It is involved in RNA and DNA production and also plays an active role in the Krebs cycle by converting carbohydrates to glucose. Thiamine can be used to treat anemia, paralysis, movement and memory disorders, energy loss and depression.

Riboflavin (Vitamin B2)

Riboflavin can be found in grains, meat, milk, peas, cheese, and eggs. Riboflavin plays an important role in maintaining mucous membranes, nerve sheaths, eyes, and skin. Riboflavin deficiency can lead to oral and skin problems as well as anemia. Riboflavin supplements can be used for preventing migraine headaches and cataracts and to treat blood disorders such as red blood cell aplasia and congenital methemoglobinemia. Riboflavin can cause the urine to turn a yellow-orange color, and large doses can cause diarrhea.

Niacin (Vitamin B3)

Niacin can be found in meat, potatoes, legumes, milk, eggs, and fish. Niacin plays a vital role in metabolism and helps to maintain the gastrointestinal tract, the skin, and nerves. Niacin insufficiency can lead to a disease called pellagra which is defined as a set of symptoms that includes dementia, dermatitis, and diarrhea. Niacin is generally used for reducing high cholesterol and treating pellagra. However, cramps, nausea, itching, flushing and skin breakouts can occur if too much niacin is taken.

Pantothenic acid (Vitamin B5)

Pantothenic acid can be found in legumes, meats, and whole grain cereals. Pantothenic acid helps in the breakdown of carbohydrates, amino acids and lipids. There is very little scientific evidence to support the use of vitamin B5 as a supplement.

Pyridoxine (Vitamin B6)

Pyridoxine can be found in organ meats, fish, soybeans, butter, and brown rice. Pyridoxine plays an important role in metabolism and the production of amino acids. Low pyridoxine levels can lead to mouth irritation, skin and nerve damage, and confusion. Pyridoxine can be used to treat sideroblastic anemia and reduce high levels of homocysteine which is a substance thought to play a role in heart disease. An IV injection of pyridoxine can also treat some types of infant seizures. Overdoses of pyridoxine can cause nerve damage.

Biotin (Vitamin B7)

Biotin can be found in egg yolks, mushrooms, brewer’s yeast, and beef liver. Biotin is a critical coenzyme in the carboxylation reactions of the Krebs cycle. It plays a vital role in the conversion of carbohydrates to glucose. Biotin is used to treat scaly dermatitis which is a skin disorder affecting mainly the scalp, face and torso. It is also used to treat hair loss, depression and exhaustion.

Folic Acid (Vitamin B9)

Folic Acid can be found in liver, green vegetables, yeast and whole grain cereal. Folic acid is a very important vitamin for pregnant women because it plays a vital role in fetal brain and nerve development. It also helps with protein metabolism, DNA and hemoglobin synthesis, and red blood cell formation. Low folic acid levels can lead to birth defects, poor growth, mouth irritation and anemia. Folic acid can be used for reducing homocysteine levels in people with renal disease and to reduce the harmful effects of methotrexate. Large amounts of folic acid can result in poor zinc absorption and convulsions.

Cobalamin (Vitamin B12)

Cobalamin can be found in meat, liver, eggs, milk and poultry. It is the only B vitamin that does not exist in plants which can be a major concern for vegans. Like other B vitamins Cobalamin plays a critical role in blood cell formation, the metabolism of food, and DNA synthesis. Pernicious anemia, mouth irritation and brain damage are all major side effects of a Cobalamin deficiency. Most vitamin B12 deficiencies are due to the stomach’s inability to produce intrinsic factor which is an enzyme that helps the intestines absorb vitamin B12. Therefore, if vitamin B12 is administered it must be accompanied by intrinsic factor.

Vitamin B Deficiency

Vitamin B is available in dark green vegetables, grains, and meat, but the problem is getting enough in your regular diet. Deficiencies of vitamin B6 and B12 are very common in the general population. In addition, as one age the ability to absorb vitamin B can become compromised, such as by stomach disorders or other prescribed medications. Pregnancy also draws heavily on your bodies vitamin stores. This is where supplementation is often considered.

Supplements

Supplementation with B vitamins is usually done via a complex formula that has all 11 B vitamins in it; however, you can get just a single B vitamin if you prefer. For extreme deficiencies, shots of B12 may be recommended by a physician who wants to bypass the absorption mechanism altogether. Most people only need supplementation with capsules, tablets or liquids.

B vitamins shouldn’t be ingested on an empty stomach. They can make you nauseous if they are not taken with food. Ideally, the tablet should be taken after a meal and earlier in the day, not later. Since B vitamins boost energy levels, they can act as a stimulant and also cause a restless sleep. Look for supplements that have the recommended daily value and do not try to overload your system unless under a doctor’s orders to increase the levels substantially.

B vitamins tend to be very safe at recommended levels. However, they do turn the urine a strong yellow color, which is not harmful. However, if you take too much Niacin (B3), then you could cause some flushing and liver damage. You won’t be overloading your system with a regular multivitamin supplement, but sometimes doctor’s prescribed much higher doses of Niacin when they are trying to help patient’s control their cholesterol levels. One other vitamin with a serious side effect, when taken in large doses, is vitamin B6. It will cause nerve damage if taken in excessive dosages. To remain safe make sure that your vitamin B6 is only 200 mg or less each day.

    I think this is a brilliant and informative post. Because of too much booze in the past I am now on Thiamine for the rest of my life ~ and it’s very noticable if I miss taking it for a few days.

      Thank You Mr. Collier. I too have “issues” that require certain medications for previous life experiences! My fascination with Biotin arrived when my hair started falling out in masse. Not certain exactly why {I have my concerns tho}. Again, Thank You!
