Benefits of Vitamin B5, Sources and Deficiency

Vitamin B5 is also known as pantothenic acid. Its name is derived from the Greek word pantos meaning "from everywhere," as small quantities of pantothenic acid are found in nearly every food.

In its functional form, vitamin B5 gets combined with another small, sulfur-containing molecule to form coenzyme A (or CoA). This conversion allows vitamin B5 to participate in a wide variety of chemical and organic reactions. Coenzyme A is needed to carry out various metabolic functions, and for the generation of energy in the form of ATP from fats, carbohydrates and proteins.

Roger J. Williams, the discoverer of pantothenic acid suggested that Vitamin B5 might be helpful in the management of certain medical disorders, such as rheumatoid arthritis.

Functions of Vitamin B5 -

* Vitamin B5 is also known as the anti-stress vitamin at times. It is one of the eight water soluble B complex vitamins.

* Vitamin B5 helps production of the cellular antioxidant glutathione, and is therefore an essential vitamin for all life forms.

* Helps in the break down carbohydrates, proteins and fats for energy - thus a stamina enhancer.

* This vitamin plays an important role in production of adrenal hormones in the adrenal glands.

* Vitamin B5 helps to produce neurotransmitters, cholesterol required for proper nerve and muscle performance.

* It is also responsible for haemoglobin production and metabolism of toxins by the liver.

* It plays an important role in cell division, DNA reproduction and RNA transcription.

* It regulates the formation of stress hormones and hair pigmentation.

Deficiency of Vitamin B5 -

It is an unlikely that an adult will have a deficiency of vitamin B5 because of the availability of B5 in many foods, plus the fact that it is also produced by our intestinal bacteria.
However, a deficiency of Vitamin B5 causes fatigue, muscle weakness, personality changes, psoriasis, and headache. Vitamin B5 is often used to treat the symptoms of rheumatoid arthritis, edema, swelling, pain, and stiffness in joints.

Pantothenic acid is also recommended to prevent stress and relieve insomnia, arthritis, food intolerance and teeth grinding.

Oral application of pantothenic acid helps relieve many skin problems and cure wounds.

Who are at risk of Vitamin B5 deficiency?

* Women who are on birth control pills are recommended to take extra doses of Vitamin B5.

* Smokers and alcoholics also fall under this category.

* People undergoing stress, prone to allergies or eating too many refined foods might develop a shortage of this vitamin.

Symptoms of Vitamin B5 deficiency -

· painful & burning feet

· skin abnormalities

· numbness and poor coordination

· abdominal and muscle cramps

· vomiting

· anaemia

· insomnia and depression

· stunted growth

· restlessness

Most of these symptoms and signs get resolved with external administration of pantothenic acid.
Vitamins B12, folic acid and biotin are required for proper use of vitamin B5 in the body's biochemical activities. In addition, vitamin C somewhat helps prevent B5 deficiency.

Dosage of Vitamin B5 -

Since deficiency of pantothenic acid is rare, so there is no recommended daily intake for this vitamin. Pantothenic acid is mostly included in B-complex multivitamins. The RDA for men is 10 mg and women is 8 mg.

Normal daily intake of pantothenic acid for adults is 4 to 7 milligrams. Vitamin B5 should be taken with water, preferably after eating.

Pantothenic acid does not usually cause any side effects, but pregnant and lactating mothers should be careful to consume only the normal daily intake.

Dietary sources of Vitamin B5 -

The term pantothenic acid is derived from the Greek word pantos, meaning everywhere. Vitamin B5 is widely distributed in plant and animal food sources, where it occurs in both bound and free forms.
Pantothenic acid is richly found in peanuts, liver, kidney, cauliflower, mushrooms, seeds and other nuts, pumpkin, mushrooms, legumes, sweet potato, milk, soya, cheese, egg yolk, fish, chicken, wholegrain bread and cereals, and bananas. The richest sources of the vitamin are the ovaries of cod and tuna fish.
Breakfast cereals are also a good source if they have been fortified with pantothenic acid.
Do not add soda to the water used for cooking vegetables - it will destroy the pantothenic acid.

Vitamin B5 storage -

Vitamin B5 is relatively unstable in food, and significant amounts of this vitamin can be lost through cooking, freezing, and commercial processing.
Vitamins are easily destroyed and washed out during food preparation and storage. Store vitamin supplements at room temperature, in a dry place that is free of moisture.

Vitamin Supplements and Women's Health

If you are not eating a healthy diet, the first thing you need to do is make necessary improvements for your nutritional needs. Women can also benefit from taking a good multivitamin with iron. Many women of reproductive age are slightly anemic, meaning they have a lower red blood count than they should because of their menstrual cycle every month. This can cause a loss of iron every month.

Women can have a higher blood count when they replace loss of iron by taking a multivitamin supplement with iron. Another benefit from taking such a supplement it can also cause them to have less tiredness and more energy.

Women who have tender breast can find a vitamin E supplement helpful. Women have found taking up to 1,000 IU (international units) per day have relief with this problem. But taking this much of the vitamin some women have found side effects such as becoming irritable, bloated, or having oily skin. Women who have reduced their intake to 400 IU find they still find relief from breast discomfort without the side effects.

Women who suffer from premenstrual syndrome have found vitamin B6 beneficial.

Women over the age of thirty five need to take extra calcium every day. Women from the age of thirty five until menopause need 1,000 mg of calcium every day. 1,500 mg per day is needed after menopause. Women who take estrogen after menopause only need 1,000 mg per day because of the effects of estrogen on their bodies they will not require the extra calcium.

The Journal of the American Medical Association revealed that taking prenatal vitamins for six weeks or longer before getting pregnant offered some protection against neural tube defects in the baby. The key element seems to be folic acid.

Most obstetricians agree it is good for women who are planning to become or are pregnant to take prenatal vitamins. They find women benefit from the additional calcium, folic acid and extra iron during pregnancy. Over the counter prenatal vitamin supplements work fine.

Excessive amounts of vitamins should not be taken. Excessive doses of vitamins A, D, E, and K should be especially avoided. This can be harmful. Disease may result if the vitamins are absorbed in the body's fat and accumulated in large amounts.

Women who will benefit from taking vitamin supplements particularly are people with specific diseases that make vitamin intake necessary, the elderly and often premature infants. Also, those who are inclined to avoid healthy eating habits!

Vitamin E Oil

Vitamin E is described as the "lightening rod" of the cell, allowing reactive molecules to strike the cell without damaging it. This is apparent in the case of skin, where vitamin E protects the skin from ultraviolet radiation. Vitamin E-rich foods, when taken, can directly travel to the skin cell membranes and protect the skin.

Vitamin E comes in the form of gels, capsules and oils. Oils and gels can be applied topically to help protect the skin and also for scars. Vitamin E contains alpha-tocopherol, either 100 % pure or mixed. Alpha-tocopherol in its natural form is powdery and thick. Hence, it is mixed with a carrier like olive oil. Vitamin E oil is processed from vegetable oils like corn, soya and canola through vacuum distillation. It is heavy and viscous.

Vitamin E oil has a shelf life of about two to three years. When exposed to air, it reacts with oxygen and hence becomes inactive, resulting in a reduced shelf life and potency. Similarly, exposure to extreme heat also reduces the shelf life. As such, vitamin E oil should be stored under well-protected conditions.

Generally, manufacturers of vitamin E oil add ingredients like glycerides, and therefore, vitamin E content may be in the range of 18-20%. The IU value of the oil (International Units, 100 IU is equal to 67 mg for natural vitamin E and 45 mg for synthetic) may vary from manufacturer to manufacturer, depending on the type of tocopherol present and the percent in the oil. For instance, oil processed from soya will be rich in gamma-tocopherol.

Synthetically produced vitamin E oil comes in the form of esters of tocopherols, mostly acetates and succinates. The esters are more resistant to oxidation during storage than unesterified tocopherols. These are mainly used in pharmaceutical formulations and food formulations to fortify food. They are packed in soft gelatin capsules. The bioavailability of these esterified tocopherols is same as that of unesterified ones and is measured in IU.
