1. What is Vitamin B5?

 most commonly called pantothenic acid

 member of the B-complex family of vitamins first researched in the 1930-1940s as a required growth factor for many kinds of organisms, including yeasts, birds, and rodents.

 name of the vitamin comes from the Greek word pantos, meaning “everywhere.” Vitamin B5 is almost universal present in nature – including in virtually all types of food.

 In its metabolically active form, vitamin B5 gets combined with another small, sulfur-containing molecule to form coenzyme A (or simply, CoA). This conversion allows vitamin B5 to participate in a wide variety of chemical reactions.

2. What is the function of Vitamin B5?

Regulation of skin oil

B5 helps regulate oil by helping with the metabolism of fats in the body, and in the skin. oฌnce the fats are metabolized, they no longer need to be excreted through the sebaceous glands.

Release of Energy from Carbohydrates and Fats

When found in its CoA form, vitamin B5 plays a pivotal role in helping release energy from sugars, starches, and fats. Increased levels of vitamin B5 in the blood of marathon runners, for example, has led to interest in this vitamin as a potential aid in physical training, where sustained energy release from the mitochondria is critical. For this reason, vitamin B5 has been reported to aid weight loss.

Production of fats

While the CoA form of vitamin B5 is important for releasing energy stored as fat, it is equally important for the creation of fat. Two basic types of fats – fatty acids and cholesterol (both essential to a healthy body) – both require the CoA form of B5 for their synthesis.

Changing the shape and function of proteins

Sometimes it is important for the body to make small chemical changes in the shape of cell proteins. One way for cells to accomplish this task is by attaching a special chemical group, called an acetyl group, to the proteins. Vitamin B5, in the form of CoA, can be used to help acetylate proteins, thereby protecting them from chemical breakdown. This process is especially well-researched in relationship to the body’s adrenal glands, where stress-related hormone production requires participation of vitamin B5.

3. What are deficiency symptoms for Vitamin B5?

 Fatigue

 Listlessness

 sensations of weakness

 “burning foot syndrome” – numbness and tingling, together with burning and shooting pain in the feet

4. What are toxicity symptoms for Vitamin B5?

 At very high supplemental doses of 2 or more grams per day, intake of vitamin B5 can cause mild diarrhea.

 Lower doses of this vitamin (in the 500 milligram range) have also been used to treat constipation due to this association with diarrhea.

 Other than temporary diarrhea at high does of vitamin B5, no other toxicity symptoms have been reported in literature. Thus, no Tolerable Upper Limit (UL) was established by the Institute of Medicine at the National Academy of Sciences in its 1998 public health recommendations for vitamin B5.

5. How do cooking, storage, or processing affect Vitamin B5?

 Pantothenic acid is relatively unstable in food, and significant amounts of this vitamin can be lost through cooking, freezing, and commercial processing.

 Research on frozen foods has shown a loss of 21-70% for vitamin B5 in animal products (like meats), and similar losses for processed grains (like cereal grains) and canned vegetables.

 Fruits and fruit juices lose 7-50% of their vitamin B5 during processing and packaging.

6. What factors might contribute to a deficiency of Vitamin B5?

 poor dietary intake

 digestive problems – proper digestion is required to release vitamin B5 from the CoA form and allow it to be absorbed into the body from the small intestine.

7. What medications affect Vitamin B5?

No detrimental drug reactions have been reported for vitamin B5.

8. How do other nutrients interact with Vitamin B5?

In animal studies, vitamins B12, folate, and biotin are required for proper use of vitamin B5 in the body’s biochemical pathways. In addition, vitamin C appears to help prevent B5 deficiency.

9. What health conditions require special emphasis on Vitamin B5?

Vitamin B5 may play a role in the prevention and/or treatment of the following health conditions:

•Acne
•Excess skin oil or overactive oil glands
•Adrenal insufficiency
•”Burning foot” syndrome
•Cataracts
•Chronic fatigue syndrome
•General fatigue
•Hyperlipidemia (high levels of fat in the blood)
•Osteoarthritis
•Rheumatoid arthritis

10. What forms of Vitamin B5 are found in dietary supplements?

Common forms are Pantothenic acid and calcium-D-pantothenate.

11. Good sources of Vitamin B5

Crimini mushrooms, raw
Cauliflower, boiled
Broccoli, steamed
Calf’s liver, braised
Turnip greens, cooked
Sunflower seeds, raw
Tomato, ripe
Strawberries

Mineral Makeup Foundation Tips

It seems mineral makeup foundation has become a buzz word these days, so many people decide to give it a try. There is a great deal of disappointment because mineral makeup foundation is somewhat trickier to apply than liquid foundation is. Here are some tips to get that flawless finish.

1. Choose The Best Shade For Your Skin

The best place to test for a match to your skin tone is along your jaw line near your neck. You can also use the fleshy part of your hand or your wrist. If you are unable to do a shade test, then take the sealed jar and match the shade closest to your wrist.

If you are trying to cover up blemishes or uneven skin tones many professionals recommend that you go one to two shades darker. Dont worry unlike cream foundation it wont look dark. Mineral foundation brightens your complexion.

2. Properly Prepare Your Skin

All makeup goes on best when the skin has been properly cleansed and then moisturized. This is especially true with dry skin. You should always let the moisturizer soak in completely. If you have oily skin, rather than a foundation opt for a foundation primer.

3. Around and Around You Go

For the best coverage use your kabuki brush which is a shorter, denser brush. Dip your brush into the mineral makeup foundation, then push the bristles against the back of your hand to push the powder into the brush. Tap off the excess. Use continuous circular motions to apply your mineral foundation to your face, working from the t zone out.

4. Finish it Up

You can use mineral powder concealer where necessary. If you need a little more coverage just dip your flat concealer brush into your mineral makeup foundation, tap the excess off, and press the remainder into the trouble spot.

If your skin is oily you should look for a matte finish, or consider using a mineral finishing powder on top of your mineral foundation. Apply the same way with light, circular brush motions. This will create a pore free natural matte finish. It also helps your foundation stay on longer.

5. Complete the Rest of Your Makeup

Now just finish up your eyes, lips, and cheeks and youre ready to look and feel great.

Its not surprising that mineral makeup has become so popular. With a little practice your mineral foundation and the rest of your makeup will look fantastic.

Best of all its natural and people with sensitive skin seem to handle it well. Of course you should always do a skin test to be sure. Titanium dioxide and zinc oxide have healing qualities which helps to reduce acne. The zinc oxide also dries acne.

There are many different mineral makeup foundation brands on the market starting at around $10, so shop around and find the best coverage and price. Now that you have some great tips why not giver it a try?

Skin Whitening Beauty Tips – What You Should Know About Skincare Meant to Make Your Skin Fairer

My. Fair. Beauty. Fair skin is sexy. A lady with fair fine skin is regarded as a fair beauty.

For centuries, men have equated fair skin on ladies with beauty. Even today, although tan skin is appreciated in the west, most cultures prize fair skin. Men love fair beauties. Not the sickly white, corpse-like complexion, but fair, translucent and radiant with a healthy rosy flush.

With sun exposure, even wearing an SPF 50 sunblock will not prevent your skin from darkening. That fair, white complexion is hard to attain and just as hard to maintain.

In the past, women would stay out of the sun as far as possible in order to prevent their skin from darkening. If they had to go out in the sun, they would carry parasols to protect themselves from the suns skin-darkening rays.

Whitening home remedies have been in existence for as long as fair skin has been in vogue. In the kitchen, a woman might mix egg white with lemon juice to use as a facial mask to lighten the skin.

Licorice root contains substances that fade away the pigmentation in the skin and hence is used in many skin lightening products. Hydroquinone is another potent skin lightening ingredient used in skin whitening treats. It disrupts the production of melanin and hence prevents skin from darkening. Arbutin is another skin lightening ingredient that works by inhibiting the production of melanin.

Many of the skin whitening products contain plant extracts to give you fairer skin. Mulberry, white mulberry and paper mulberry contain arbutin which makes skin fairer by preventing your skin from darkening. Elizabeth Ardens Prevage White Concentrate Brightening Serum has Soy Ferulate-C.

Most whitening skincare products make skin fairer by sloughing off the darkened surface of the epidermis. Alpha hydroxy acids like lactic acid and glycolic acid remove hyperpigmented skin cells and boost cell turnover, hence making skin fairer. Garnier light night overnight whitening peeling cream uses AHAs to peel the skin and slow down melanin production.

Then there are those that prevent skin from darkening by inhibiting melanin production. Melanin is the pigment that gives skin its color. More melanin is produced when the skin is exposed to sunlight. Vitamin C, Kojic acid, Azelaic acid, Arbutin and Hydroquinone are substances often used in skin whitening products to lighten your skin through the inhibition of melanin production. Biotherm white detox targets RAB27 which would otherwise support the melanin that would cause dark spots.

Typically, whitening skincare products treat the epidermis at most. Recently, Lancome has come up with a range that treats the dermis as well as the epidermis. Since UV rays penetrate the dermis as well as the epidermis and causes inflammatory messengers to stimulate melanocytes to produce melanin which causes skin to darken, Lancomes blanc expert GN-White generating new whiteness spot eraser targets these inflammatory messengers on the epidermis and dermis to prevent the darkening of the skin.

This is done through the use of sphinganine and mint to neutralize those signals so that melanocytes arent stimulated to make melanin.br

Reduce Acne With a Simple Daily Skincare Routine

A well-structured daily skin care routine can prevent acne, but it can hard to figure out what needs to be done to keep your skin clear. Any good skincare routine involves cleansing, toning, and moisturizing your skin. The part that I used to forget to do was moisturizing, which is the most important part of all. Without moisturization, your skin either ends up dry and scaly or, in my case, seems to kick up oil production and feel greasy. The first step, cleansing, removes surface dirt and clears your pores. It also removes oil from the top of your skin, which leaves your skin feeling less greasy. I apply cleanser with cotton squares, applying cleanser all over my face once to remove most of the oils, and then again to make sure everything is completely clean. Toning improves your skins quality. Depending on how oily your skin naturally is, you want to adjust the alcohol level of your toner. Oilier skin requires a toner with greater alcohol content to remove the oil, whereas dryer skin should not be toned with high-alcohol toners. For extremely dry skin, rose water or similar toners do the trick. A water-based moisturizer helps keep your skin from drying out (or over-producing oil). Without moisturizing, your skin can easily get overly dry and uncomfortable, especially during the winter months. Generally, I use a moisturizer with an SPF rating, to prevent sun damage to my skin when I go out. You should only use an oil-based moisturizer if you have excessively dry skin, as oil based moisturizers can make naturally oily skin extremely greasy and shiny. Im obsessive about my skin, so I cleanse and moisturize twice a day, only toning in the morning. I feel that going to sleep with oily skin is just asking for trouble.br
