The B5 vitamin is also known as Pantothenic Acid. The B5 vitamin is the
most prolific of all the vitamins and is found in every type of food.
In fact, it is impossible for a person to consume less B5 vitamin than
they need. That means that there is no little possibility that a person
can have a B5 vitamin deficiency.

Vitamin E is one of the most important vitamins for people, so we should pay particular attention to this amazing vitamin and consider to some benefits of it.1) Vitamin E and Skin CareSkin and lip protection are also well-known health benefits of vitamin E. Vitamin E helps retain moisture in the skin and prevents dryness, itchiness, and chapping. It also protects against UV radiation and speeds up wound healing. It can be applied topically and is a main ingredient in most creams, lotions, and sunscreens.Vitamin E prevents acne via antioxidant protection. Several clinical investigations have elucidated the relationship between vitamin E and acne.In addition to this study, a report in Clinical & Experimental Dermatology detected a direct link between blood levels of vitamin E, and acne. In this investigation, researchers compared the blood levels of vitamin E in 100 newly diagnosed, yet untreated acne patients to 100 age-matched, healthy volunteers without acne. Overall, the healthy, acne free group had higher amounts of vitamin E in their circulatory system than the acne sufferer group.Based on these findings, investigators concluded that low vitamin E blood levels could cause or aggravate an acne outbreak.2) Vitamin E and DiabetesVitamin E is one of the most important vitamins for people with diabetes. The role of vitamin E in the diet of the diabetic is to improve insulin activity and acts as a blood oxygenator by performing as an antioxidant. The onset of Type 2 diabetes is seen more often in diabetics that have been shown to have low blood levels of vitamin E. Vitamin E improves glucose tolerance in non-diabetic elderly and adults with Type 2 diabetes (NIDDM).Damage caused by free-radicals in the blood stream is associated with a deficiency of Vitamin E. The lining of the vascular system can be damaged by the lack vitamin E. This damage to the vascular system may be prevented by the antioxidant activity of vitamin E. Increasing the vitamin E level in diabetics can protect the diabetic from diabetic cataracts.3) Vitamin E and Hair LossVitamin E is effective in increasing peripheral circulation through oxygen uptake with benefits to the scalp. It is also possible vitamin E helps the body’s immune function which in turn stimulates hair growth.Vitamin E for hair loss should be treated with a little caution. As increased vitamin E intake can cause adverse reactions when combined with some medications it is wise to consult with a medical practitioner before taking large quantities if you regularly take medication for other health conditions.Interestingly vitamin E was used in the fur industry to promote healthy fur in animals and it is still used today in certain supplements for pets to contribute to healthy fur.4) Vitamin E and Heart DiseaseVitamin E prevents cholesterol from being converted to plaque, which thickens the blood vessels and leads to stroke and heart disease. Vitamin E can also prevent blood clots that lead to blocked arteries and heart disease, although the American Heart Association suggests that more research is needed before they will recommend vitamin E supplementation to prevent heart disease.It also thins the blood and improves blood flow even with plaque buildup on the artery walls. Studies show that vitamin E from foods can reduce the risk of stroke in postmenopausal women, although further studies are needed to support this claim.Vitamin E is one of the antioxidant vitamins. These vitamins have the ability to neutralize harmful free radicals in the body that can cause serious disease such as cancer.

B complex, once thought to be a single vitamin, is now classified as 12 related water-soluble compounds. Four can be synthesized by the body and include inositol, PABA (para-aminobenzoic acid), choline and lipoic acid. The remaining eight are not made in the body and are considered essential to good health (1).

B1 (thiamine) acts as a coenzyme (2) in metabolizing nutrients. Deficiency has been known to lead to heart and nervous system problems.
B2 (riboflavin) is crucial to co-enzymatic reactions. Inadequate amounts may cause the lining of the mouth and skin to swell.
B3 (niacin) is essential to healthy metabolism. Deficiencies are purported to cause cognitive slowing and inflammation of skin and orifices.
B5 (pantothenic acid) is important to the oxidation of fats and carbohydrates.

B6 (pyridoxine) is an important cofactor for enzymes. Inflammation of the skin and mouth, nausea, vomiting, anemia, fatigue and dizziness can result from deficiency.
B7 (biotin) aids in the healthy reproduction of cells and is crucial to cell and body growth.
B9 (folic acid, folate) is needed for nucleic acid synthesis (the making of genetic material). Too low levels of B9 have been known to result in megaloblastic anemia.
B12 (cobalamin) is also needed for nucleic acid synthesis. Both megaloblastic and pernicious anemia (lower than normal red blood cell count) can result from cobalamin deficiency.
Inositol is a naturally occurring sugar in the body that aids nerve health.
Choline is a constituent of lecithin (a compound which breaks up fat and cholesterol) and essential to fat metabolism.

PABA (para-aminobenzoic acid) helps in metabolizing protein and forming red blood cells.
Lipoic acid functions as an antioxidant in the body to protect cells against free radical damage.

(1) There are 13 vitamins said to be essential for normal cell function, growth and development. Eight are B complex vitamins (source: Medline).
(2) Coenzymes are organic molecules that work in concert with enzymes to utilize vitamins and minerals in the body. They’re essential to healthy metabolism.

Sources of B complex

Although prevalent in many foods, natural sources high in B complex vitamins include meat and dairy products.

Dark green, leafy vegetables are excellent sources of folic acid (B9).

Cobalamin (B12 – essential to healthy red blood cell count) can be derived only from animal sources. For this reason, strict vegetarians are encouraged toward B complex supplementation.

Unless some type of deficiency is present, or an individual has a problem absorbing B complex vitamins, sufficient amounts of B complex vitamins can be obtained from diet alone. However, B complex supplements are used every day by millions looking to balance diet.

B complex health benefits and claims

B vitamins serve a wide range of health functions. They work both together and separately to ensure a healthy metabolism and aid the body in absorbing and utilizing nutrients. B complex vitamins help maintain the outer cover of nerve cells (myelin) and assist in converting nutrients to energy.

Together, three members of the B complex group, pyridoxine, cobalamin and folic acid, have been scientifically proven to lower blood homocysteine, a toxic by-product of cellular metabolism associated with heart problems.*

Research links B complex vitamins to a decrease in neural tube defects and are associated with healthy immune function and normal cell growth and hormone production. B complex may also play a role in fighting free radicals that result in signs of aging. B complex vitamins are said to be essential for healthy skin, hair and nails.*

Thiamine (B1) is said to be supportive of cognitive function in both younger and older persons.*

Niacin (B3) may help balance cholesterol and triglyceride levels in the body, resulting in healthy blood glucose levels.*

Riboflavin (B2) supplementation has been linked to decrease in frequency for those suffering regularly from migraine headaches.*

Mood problems and mental acuity may be improved through cobalamin (B12) supplementation.

*Statement not evaluated by FDA.

RDI or RDA of B complex

There is no one figure that denotes the cumulative RDA or RDI of B complex vitamins. Each B vitamin has its own recommendation, which varies from source to source and is based on age, gender, overall health and alcohol and nicotine consumption. Some B vitamins such as inositol and choline have no standard RDA or RDI. Because the balance of B complex in the body is often crucial to good health and a deficiency or too high level of any B vitamin might lead to a number of disorders, nutritionists suggest that healthy people refer to charts that exhibit conservative B complex intakes. Others who may be suffering from too much or not enough B complex should consult a physician regarding intake. A preferred Internet source for B complex supplementation amounts is the USDA National Agriculture Library at www.nal.usda.gov/.

B complex deficiency and symptoms

Because B complex vitamins occur in food in abundance, two prevalent ways to become deficient in B complex vitamins are a poor dietary intake of foods which contain B complex vitamins and physical problems absorbing B complex vitamins.

Poor dietary intake of B complex vitamins (most frequent among strict vegetarians and the malnourished) can be offset with vitamin B supplementation.

Poor absorption of B complex vitamins may result from thyroid dysfunction and the lack of Intrinsic Factor in the stomach (common to the elderly and those who abuse alcohol and tobacco).

B complex deficiency can occur at varied levels in different individuals. Signs include poor skin, hair and nail health, memory loss, nervousness, profound fatigue, sleep disturbances, nausea, poor appetite, frequent infections and mood disorders. It’s advisable to search the Internet for more extensive information regarding the specifics of B complex vitamin deficiency or consult a nutritionist or physician.

B complex toxicity and adverse effects

For the most part, excessive amounts of water-soluble vitamins, such as B complex vitamins, are excreted as waste when not used by the body for energy, resulting in little chance of toxicity when taken in large amounts. Adverse effects of B complex vitamins have been reported as rare and minor. Literature does suggest, however, that:

Too high levels of niacin (B3) in the body may result in inflammation of the liver and high blood sugar levels.

High doses of pyridoxine (B6) may inflame the liver as well and damage nerve cells.

It is advisable for those with high blood pressure, chronic health conditions or individuals who take seizure medications to consult a physician prior to starting a regimen of B complex supplementation, as certain drug interactions may result.

Clinical studies and B complex research

Although B complex supplementation is well positioned in the marketplace as a health benefit, findings from both animal and human studies differ and are suggestive. Research uncovered in a report entitled “B Vitamins and Berries and Age-Related Neurodegenerative Disorders” published by the Department of Health & Human Services shows that while animals kept deficient in folate (B12) may suffer from neurological damage in the long term, humans showed little to no positive neural response when given folate supplements vs. placebo.

Reports published in the New England Journal of Medicine suggest:

That despite reports of B complex vitamins as human brain food, more recent clinical evidence shows no marked improvement in thinking function, memory or overall cognitive awareness in human studies.

Notwithstanding its ability to lower dangerously high levels of homocysteine (1) in the blood, B complex may have no positive impact on the cardiovascular health of high risk patients.

B complex efficacy and the FDA

The FDA goes as far as to allow dietary supplements that contain folate, vitamin B6 and vitamin B12 a qualified health claim that suggest these B complex vitamins may have health merits – but the evidence is inconclusive. Regardless, research indicates more benefits than risks with B complex supplementation because toxicity and overdose are highly improbable.

Also phylloquinone is known as vitamin K1 carrying four isoprenoid residues in the side chain and in them one shows its unsaturation form. Vitamin K also plays an important role in the carboxylation of many glutamate residues present in proteins for the production of gamma-carboxyglutamate residues . Mostly vitamin k residues are located in the protein domains called as Gla domains. So this vitamin k’s gla-residues helps in the biological activity of all the popular Gla-proteins in the body. So in this way vitamin k aids in the movement of three physiological processes like blood coagulation, bone metabolism, and osteocalcin , matrix gla protein , and Vascular biology and many more activities .

Most of the time consumers of vitamin k suffers from allergic reaction but there is no such cases fo toxicity having high doses of vitamin k . but another form of vitamin k called as vitamin k 3 has shown the signs of toxicity in many patients.

Many of us have a hard time deciding what the best multivitamin is for us. This is completely confusing and difficult especially when there are so many bottles to scan in the various aisles of the health food store or the supermarket. One must consider every variable the vitamins and minerals listed, potency, purity, safety, storage, freshness and of course, cost. How then could one take the risk of making an uninformed choice? It is always wise to have some help.

Therefore this article will serve as a guide for selecting the complete multivitamins you need. This will assist in the decisions you make when you are looking for that multivitamin for you and your family.

Remember that the daily recommended allowance for the intake of vitamins and minerals is somehow insufficient. Over the years, Americans relied on the US RDS or the Recommended Dietary Allowance to come up with a chart of how much nutritional multivitamin supplement they should intake. Generally, this can be answered by the individual who is taking the vitamins and minerals because he or she alone knows how much dosage is intended for him or her.

Standards by the RDA may have been updated throughout the years but there has been an establishment of the minimum level of the required vitamins, minerals and nutrients which an adult must take in a daily basis. This is for him to enjoy a long life because of his health.

Nutritionists and scientist believe that the recommended dosages from the RDA may not be sufficient enough in order to prevent the diseases that could combat a persons health. In addition to this, various conducted researches have shown that the medical industry has become resistant to the recommended supplements.

It is interesting to note that the best multivitamins are those meeting the pharmaceutical standards. At the moment, there are no FDA regulations which require supplement manufacturers to comply on the standard practices while the manufacturing of the vitamins is taking place. The FDA is responsible in correcting this but ironically, there is no guarantee that the label on the bottle is what exactly is in the bottle.

The next question one must consider is whether the vitamin supplements are safe to take. Well, for one a vast majority of the ingredients in multi vitamins are safe to begin with. The case will be different if these are taken at once. The main concern though is the impact of these components when taken together.

For example, pure Vitamin A or what is known as Retinol is an essential nutrient which can become toxic once taken in large amounts. Research shows that Vitamin A is a leading cause in birth defects. But there is good news to this. A benefit of Vitamin A is realized through its alternative which is Beta Carotene. It may not have as much toxic properties but is transforms Vitamin A when needed.

Iron is another essential nutrient which most multivitamin has. However, it must also be regarded with caution despite its importance on the human body. For one, iron deficiency results to problems in the immune system like heart disease and lack of cognitive ability.

There are optimal daily intake lists that can be acquired from your doctor so you can know how much vitamins and minerals should be taken every day. Remember, the dosage varies from one person to another so its best that you ask for your doctors opinion.

The D vitamin is the only vitamin that is not obtained from foods that
are consumed. Instead, the D vitamin is actually obtained by sunlight
on the skin. There has been a lot of media coverage about the dangers
of getting too much sun but it is essential that the skin is exposed to
sunlight to obtain the recommended daily allowance of the D vitamin.

The c vitamin has got to be the most widely known vitamin these days.
It is not surprising because the body needs c vitamin for over 300
functions. In fact, the c vitamin has been proved to help protect
against heart disease, cancer and other serious illnesses.

Vitamin E helps the skin by protecting it from the sun, retaining the natural moisture of the skin, aiding in the absorption of vitamin A, fighting and preventing acne, fighting skin aging, treating sunburns, reducing the appearance of scars, and preventing skin cancer.

Vitamin E is well-known for its many health benefits. Additionally, Vitamin E also has many positive effects on the skin, aside from promoting overall health. Many beauty treatments and skincare products are now enriched with vitamin E because of this. Other natural sources of this vitamin include nuts, grains, dairy products, argan oil products and sunflower oil. The following are ways how Vitamin E nurture your skin:

Filters ultraviolet rays from the sun

Vitamin E nourishes the skin to allow natural ultraviolet protection. In fact, sunscreen lotions use vitamin E as a primary ingredient. Vitamin E in sunscreen products provides a layer of protection against the damage of direct sunlight by sealing the skin’s epidermis layer.

Maintains natural moisture of the skin

Vitamin E keeps the skin hydrated and allows the skin to seal in its moisture. Adequate moisturizing gives the skin a radiant, youthful and healthy appearance.

Aids in the absorption of vitamin A

Another important vitamin that enhances good eyesight and healthy skin is vitamin A. Additionally, vitamin A is actually an important component in most skin care applications. On the other hand, insufficient amounts of vitamin A can be harmful for the body, and vitamin E helps prevent the negative consequences of this deficiency by helping the body absorb and regulate vitamin A.

Fights and prevents acne

Vitamin E oil has profound effects on acne and blemishes. Some research has shown that vitamin E helps prevent acne and other skin breakouts. Also, people with acne claim that vitamin E helps their acne lesions heal faster when applied on the affected area.

Fights skin aging

Vitamin E has been recognized as a powerful antioxidant. It detoxifies the body by fighting free radicals. Because of this, vitamin E is effective as an anti-aging treatment and helps fight the signs of skin aging such as wrinkles and fine lines. You can decrease sun damage and wrinkles, as well as see profound effects on the texture of your skin by taking as little as 400 milligrams of vitamin E supplements daily.

Moisturizes and soothes sunburned skin

Vitamin E is calming and soothing for the skin. It is also popular for its anti-inflammatory properties. Vitamin E heals sunburns, darkened skin areas, dark spots and liver spots. In fact, slathering vitamin E oil onto the skin about 20 minutes before going out into the sun is advisable.

Reduces the visibility of scars

If you have unsightly scars or stretch marks, the regular use of vitamin E oil can have positive effects. Experts have determined that vitamin E naturally weakens the collagen strands found in scar tissues. This makes the scars more pliable so they can be treated easily.

Counteracts the formation of skin cancer

Vitamin E is effective in preventing skin cancer and severe skin damage because of its antioxidant and sun protection properties.

Either using argan oil products or taking in supplements, Vitamin E is a great addition to your diet, health, and beauty routine.
