Whether in the form of a fizzy drink or flavored lozenges, cold and flu preventative supplements almost always highlight vitamin C as one of their key ingredients. So, what's so magical about vitamin C? Also known as ascorbic acid, vitamin C is critical to living healthily. Since the human body cannot spontaneously generate this nutrient, vitamin C must instead be absorbed from outside sources, such as vitamin supplements or foods that are naturally rich in it.

Commonly found in cold and flu preventative supplements, vitamin C strengthens and speeds up immune system functionality. Though research does not indicate that vitamin C intake alone can prevent the onset of cold or flu, adequate daily intake may shorten the duration of an infection or lessen the severity of symptoms.

Vitamin C is crucial for the maintenance of well being. For example, it plays a role in wound healing and helps maintain many essential body tissues. It also acts as a potent antioxidant and can repair damage from free radicals, which are linked to aging effects, and disease vulnerability. Additionally, vitamin C can also prevent anemia, since it helps the body increase absorption of dietary iron, another vital mineral that the body cannot spontaneously create.

Foods that contain high concentrations of vitamin C have been linked with a lower risk of cardiovascular disease, like heart attack and stroke. Vitamin C can also increase levels of nitric oxide, a compound that widens blood vessels and, in turn, lowers blood pressure. In addition, regular intake of vitamin C, along with other vitamins, has been linked to a decreased risk for developing age-related cataracts, a leading cause of visual impairment in the United States.

Common Sources of Vitamin C

Vitamin C can be easily obtained through the many different foods, including:

Citrus fruits and juices (orange, grapefruit, lemon, lime and tangerine)
Berries
Melons
Mangoes
Kiwi
Tomato
Broccoli
Red peppers
Spinach
Squash
Potatoes

Cooking these foods may result in the loss of some of the vitamin content, so it is ideal to ingest them raw, either whole or juiced. Nowadays, there are also numerous packaged food products, like cereals, that have been enriched and fortified with vitamin C, so that the nutrient can be easily obtained.

Vitamin C may also be labeled as "L-ascorbic acid" in supplement form, and most over-the-counter multivitamins contain the recommended daily amount of the vitamin. While it is a good source when an individual is in need of a vitamin C boost, supplements are not meant to replace a diet rich in naturally derived vitamin C.

What Happens When You Have Too Much — or Too Little — Vitamin C?

Vitamin C is a water-soluble vitamin that can be easily flushed out of the body via urination when it is not needed. Therefore, if the main source of vitamin C is from naturally occurring foods, it is near-impossible for excess vitamin C to produce side effects. However, taking excessive concentrated vitamin C supplements may lead to diarrhea or stomach upset.

Since vitamin C-rich foods are so readily available nowadays, symptoms of inadequate vitamin C intake are also rare in the United States. However, malnourished individuals can experience symptoms of vitamin C deficiency over time, including:

Weakness
Fatigue
Anemia
Easy bruising
Joint pain
Skin breakdown
Weakened tooth enamel
Gum inflammation

Severe vitamin C deficiency is referred to as scurvy. Scurvy can be easily treated with increased dietary or supplemental vitamin C. Since vitamin C is crucial in the detoxification of the body, a lack of vitamin C can compromise the immune system and make an individual more susceptible to diseases and infections. Individuals with insufficient vitamin C may find that it takes longer than usual to recover from a cold or a physical wound.

Daily Dosage Recommendations:

The daily dosage recommendation for vitamin C is different for everyone, depending on factors such as gender, age, lifestyle and current health condition. The recommended daily dosage for vitamin C is at least 75 mg daily for women and 90 mg for men. Since people who are pregnant, breast feeding, smoking or using oral contraceptives have a lower blood level of vitamin C than others, larger doses of vitamin C may be needed to achieve optimal results in these individuals. Those who have prior or current medical conditions may also require bigger or smaller dosage levels, as recommended by their healthcare providers.

Is Vitamin C Safe For Rosacea

Is Vitamin C Safe For Rosacea

Hepatitis is a condition that causes inflammation of your liver. Currently, there are an estimated 6 million people living with hepatitis in the United States, and more than 50,000 people are diagnosed with this disease every year. There are three primary types of hepatitis, and while their symptoms can be similar, they vary largely in the ways they're transmitted. Learning more about each type of hepatitis can help you better understand the condition as a whole.

Hepatitis A is the most easily transmitted of the three viruses. It affects approximately 2,500 people every year in the United States. It typically spreads through feces-contaminated food or water and is found in the feces of people who have the virus. Hepatitis A causes a short-term, acute sickness that most people heal from without treatment. However, it can cause serious illness in some people. This virus is more common in places with underdeveloped sanitation systems.

While doctors can't treat hepatitis A with medication, people who get this virus can manage its symptoms with fluids, rest and good nutrition. There's also a safe and effective vaccine available to protect you against hepatitis A.

What Is Hepatitis B?

Hepatitis B can occur both acutely (meaning it develops quickly and lasts a short time) and chronically (meaning it develops slowly over time and worsens over months or years). According to the Centers for Disease Control and Prevention, up to 2 million people in the United States are chronically affected with hepatitis B. Hepatitis B can be transmitted through sexual activity and exposure to infected blood. It can also be passed from a parent to their newborn child during birth.

Hepatitis B usually causes short-term discomfort that many people recover from completely after about four to eight weeks. However, it can turn into a chronic condition that lasts for years; this is more likely in older adults. Doctors can treat severe chronic hepatitis B with antiviral medications. However, in most cases, treatments focus on proper hydration and nutrition. There's a safe vaccine available to protect you against hepatitis B, too.

What Is Hepatitis C?

Approximately 4 million people in the United States are affected with hepatitis C. This form of hepatitis causes a chronic illness in over 50% of people who get this type of the virus. It's the least transmissible of the three viruses and can spread through contact with infected blood.

Hepatitis C occurs more commonly in people who engage in intravenous drug use. If you received a blood transfusion before 1992, you should also get tested for hepatitis C if you haven't previously. Hepatitis C can spread through unprotected sexual intercourse, but this is a less common way to transmit it. While there's no vaccine for chronic hepatitis C, treatments that are available today offer a 95% cure rate.

Chronic hepatitis C can significantly affect how your liver works. It can cause cirrhosis, which means that your normal liver tissue is replaced with scar tissue. It can also cause liver cancer. However, there are medications that can help keep this disease in check. Making lifestyle changes, such as reducing or eliminating alcohol from your diet, can also decrease your chances of experiencing complications. In severe cases, hepatitis C may require a liver transplant.

The varying forms of viral hepatitis affect millions of people in the United States. Chronic hepatitis often has few symptoms in its early stages, so recognizing the associated dangers and getting tested if you've been exposed may save your life. Although there are five types of viral hepatitis, only A, B and C are the forms commonly found in the United States.

These Are The 6 Best Vitamin C Serums For Brighter, Clearer Skin

Amazon/Bustle

There's never a bad time to amp up your skin care regimen's sun protection defenses. Whether you're looking to keep your skin safe from future signs of sun damage or help reduce the appearance of damage that's already been done (aka sun spots), incorporating one of the best vitamin C serums into your beauty routine can help.

In an ingredients list, you'll most likely find vitamin C listed as l-ascorbic acid, which experts agree is the most effective form of vitamin C, along with tetrahexyldecyl ascorbate. You'll also want to pay attention to the concentration level of the vitamin C, as something between 10 and 20 percent is said to be the most stable, and therefore, the most effective when it comes to protecting the skin and improving its overall tone and texture.

While you can certainly apply your vitamin C serum at night, to reap its full sun-protecting benefits, apply it in the morning after cleansing, and before you moisturize and layer on your SPF (which, yes, you still need to wear). You'll also want to be careful about using your vitamin C serum after any cleansers, treatments, or moisturizers that contain salicylic acid, glycolic acid, or retinol, as this can heighten common side effects that come with these ingredients, like burning and redness (especially if you have sensitive skin).

It's also worth noting that vitamin C is a delicate ingredient because it degrades from sun exposure. Because of this, you'll want to store your serum away from the sunlight and be on the lookout for any changes in its color, texture, or smell. A serum packaged in a darker bottle is also ideal, as it helps minimize the product's exposure to sunlight.

Ahead, you'll find six of the best vitamin C serums that are all Amazon user-approved to brighten, protect, and firm your skin.

1 The Best Serum For Vitamin C Newbies

This K-beauty favorite serum contains a mild dose of 5 percent vitamin C to allow your skin to accustom itself with the active ingredient. While that's still enough to notice the brightening and skin tone-evening benefits, the smaller percentage means its also gentler and less likely to irritate skin. Reviewers love its lightweight texture and say a little goes a long way, so you only need a couple of drops. Some have even had luck with using it on their bodies to help fade unwanted scars.

Klairs Freshly Juiced Vitamin C Serum is also an Amazon-user favorite with hundreds of five-star reviews. "I used this product for a few months and then switched to one with a higher percentage of Vitamin C only to find that it didn't work nearly as well," writes one reviewer. "I'm back to using Klairs and am so impressed by the positive change I see in my skin when I use it — it's brighter, smoother, and more even — even though it's a mild product."

The only downside with this serum is that, since it comes in a clear bottle, you'll want to be extra careful with storing it somewhere away from the sun.

2 The Best Vitamin C Serum For Sensitive Skin

If you have sensitive skin, you might have luck with the low-concentration Klairs option, above. But it does contain a few ingredients that some particularly sensitive skin types negatively react to, like propylene glycol. For a super safe, all natural pick, try this all-natural pick from Mad Hippie. It uses vitamin C in the form of sodium ascorbyl phosphate, which is said to cause less irritation and reduce the risk of oxidation. Mad Hippie formulated this serum with other complementary ingredients, like vitamin E and ferulic acid, which both improve and protect the skin from damaging free radicals. And ferulic acid also helps stabilize both vitamins C and E, so that they're even more effective. To keep skin moisturized, hyaluronic acid is included in the formula, while konjac root and chamomile extract work to protect and soothe the skin. There's also a dose of clary sage, which acts as a natural toner and astringent.

"I have very sensitive skin and normally I cannot use vitamin C serums at all," writes a reviewer. "This one does not sting or burn at all." Another user notes, "Within a week or so, I saw a smoother texture to my skin. By the end of the bottle, my skin looked smoother, brighter, and three darker spots on my face [from sun damage] were at least 80 percent lighter."

3 A Vitamin C Serum That Produces An Instant Glow

Yes, all vitamin C serums brighten the skin with continued use, but The Body Shop Vitamin C Skin Boost Instant Smoother also leaves skin glowing directly after you apply it, thanks to the tiny mineral glowing particles it contains. Long-term brightening, protecting, and collagen-boosting effects come from ascorbic acid and the vitamin C-packed camu camu berries that The Body Shop has hand harvested by local collectors on the riverbanks of the Amazon River. Vitamin E provides the skin with more protection against environmental aggressors as it softens, and Community Fair Trade Brazil nut oil further moisturizes the skin. Additionally, dimethicone and glycerin give the serum a smooth texture that helps to blur pores and even out skin tone, making this a great primer, too.

4 The Best Vitamin C Serum For Acne-Prone Skin

This serum might be a bit of a splurge, but its powerful formula means serious results. The brand works with a team of assorted experts to develop each product, including geneticists, biologists, and physicians. For their iS Clinical Pro-Heal Serum Advance+, they developed a vitamin C combo that works for all skin types, including acne-prone. Time-released vitamin C means prolonged antioxidant protection, while vitamins E and A contribute even more antioxidant benefits. iS Clinical included inflammation-reducing zinc sulfate, blemish-preventing kojic acid, and nourishing olive leaf extract to combat signs of acne while helping to prevent future breakouts.

5 The Best Drugstore Vitamin C Serum

For a more affordable option, e.l.f's Beauty Shield Vitamin C Pollution Prevention Serum costs less than $20. Despite its low price, the serum still contains your vitamin C, as well as vitamin E and pomegranate extract, which provides even more vitamin C benefits. You'll also notice glycerin and hyaluronic acid on the ingredients list to leave the skin smooth and moisturized. It's even cruelty-free and vegan, and formulated without parabens, sulfates, or phthalates.

6 The Best Vitamin C Booster Powder

If you're into DIY beauty (or you just want to customize your vitamin C application), a vitamin C booster powder, like the Resurrection Beauty L-Ascorbic Acid Powder, is the perfect choice. This jar solely contains vitamin C in the form of l-ascorbic acid, which is meant to be dissolved in water or witch hazel before being added into your favorite hydrating serum. It can even be added to your nightly moisturizer, sunscreen, or body lotion. Because you're mixing this yourself, you can start with a lower concentration of vitamin C, like 5 percent, and work your way up to 20 percent (the maximum amount recommended) as your skin learns to tolerate it.

Many Amazon reviewers share the different ways they use this powder to make custom treatments. "How terrific to find cosmetic grade vitamin C to make my own solution," one raves. "All skin care experts claim this is the best for anti-aging, however very unstable. This fixes the problem and at an reasonable price. I just mix small batches to last for a week. And in just a few weeks I can see the difference in my skin." Another recommends mixing it with aloe-vera for a skin-soothing and brightening mask.

Efervescente Vitamina C

PhilipDesember 05, 2021 Tidak ada komentar

Efervescente Vitamina C

A vitamina C de 1g efervescente está indicada para a prevenção e tratamento da deficiência desta vitamina, que tem inúmeros benefícios e está disponível em farmácias com os nomes comerciais Redoxon, Cebion, Energil ou Cewin.

Em alguns casos, os suplementos alimentares com vitamina C podem conter outras substâncias, como o zinco, vitamina D ou equinácea, por exemplo, que também fortalecem o sistema imune.

Vitamina C efervescente: para que serve e como tomar

Quais os benefícios

A vitamina C funciona como uma importante vitamina antioxidante, que participa em várias reações metabólicas no organismo, como o metabolismo de ácido fólico, fenilalanina, tirosina, ferro, histamina, metabolismo de carboidratos, lipídios, proteínas e carnitina.

Esta vitamina é também muito importante na síntese de colágeno, razão pela qual está muitas vezes presente nos suplementos de colágeno. O colágeno é essencial para a manutenção da pele, mucosas, ossos, dentes e preservação da integridade dos vasos sanguíneos.

Além disso, desempenha também um papel fundamental no funcionamento do sistema imune, já que contribui para a proteção das células contra a ação dos radicais livres, bem como de espécies reativas de oxigênio, que são gerados pela resposta inflamatória. A vitamina C também é necessária para o bom funcionamento dos glóbulos brancos, sua movimentação, eliminação de vírus e bactérias e cicatrização de feridas.

Veja quais os principais sintomas de falta de vitamina C.

Para que serve

Por todos os benefícios que apresenta, a vitamina C efervescente é indicada como suplemento vitamínico nas seguintes situações:

Reforço do sistema imune, em casos de gripes e resfriados, por exemplo;
Antioxidante;
Cicatrizante;
Auxiliar nas doenças crônicas;
Dietas restritivas e inadequadas;

Além disso, pode também ser usada como auxiliar nas anemias com carência de alguma vitamina ou mineral. Conheça os principais tipos de anemia e como tratar cada uma delas.

Como tomar

Geralmente, a vitamina C efervescente está disponível em diferentes doses, podendo estar associada a outras substâncias, como o zinco ou vitamina D e a posologia deve ser determinada pelo médico mediante a necessidade, história clínica da pessoa e idade. Existem ainda formulações de vitamina C que podem ser dadas a crianças e a grávidas, que têm dosagens mais baixas.

A posologia da Vitamina C efervescente em adultos e crianças maiores de 12 anos é de 1 comprimido efervescente, que equivale a 1g de vitamina C por dia, diluído num copo de água com cerca de 200 mL, em qualquer horário. No entanto, antes de fazer este tratamento, deve-se falar primeiro com o médico.

Quem não deve utilizar

A vitamina C efervescente não deve ser utilizada em pessoas que tenham alergia a qualquer um dos componentes do medicamento, pessoas com história de pedra nos rins por oxalato ou com eliminação de oxalato na urina, pessoas com insuficiência renal grave ou falência renal, com hemocromatose ou menores de 12 anos.

Além disso, também não deve ser usado em grávidas ou mulheres amamentando, a não ser que seja indicado pelo médico.

Possíveis efeitos colaterais

Embora seja raro, podem ocorrer alguns efeitos colaterais como diarreia, náuseas, vômitos e dores gastrintestinais e abdominais e reações alérgicas.

Does Vitamin C Help Dark Spots

Does Vitamin C Help Dark Spots

amazon, dermstore

As far as buzzy skincare ingredients go, vitamin C is one of the most talked about — and for good reason. "Packed with antioxidants, vitamin C has shown to improve dull skin texture and tone, fight free radical damage, reduce signs of aging, dark spots and hyperpigmentation, hydrate, increase collagen production, brighten and provide anti-inflammatory effects," says Geeta Yadav, M.D., a board certified dermatologist and founder of Skin Science Dermatology.

"Also known as ascorbic acid and L-ascorbic acid, vitamin C provides antioxidant protection, as it uses electrons to neutralize the free radicals found on skin from environmental stressors like solar radiation and pollution," says Good Housekeeping Institute Beauty Lab chemist Danusia Wnek. Additionally, vitamin C blocks the enzyme responsible for melanin (or pigmentation) production, which means it can help brighten skin. Dr. Yadav explains that because the vitamin is a water-soluble nutrient, it can be used topically in many different forms, including vitamin C serums.

In theory, everyone can incorporate a vitamin C serum into their skincare routine. However, Ellen Marmur, M.D., a New York based dermatologist and founder of Marmur Metamorphosis Skincare, cautions that too much vitamin C can potentially irritate skin. It depends on your skin type, but she personally recommends products that contain between 10-15% potency for best results.

The Good Housekeeping Institute regularly tests skincare products to find the best ones on the market. When we review vitamin C serums, we look for technology to preserve the vitamin C, unique packaging to protect against light degradation and ingredients with synergistic benefits to improve efficacy. The below picks reflect our Lab picks, Good Housekeeping Seal-holders and top-rated items from our favorite trusted brands, plus favorites from consumers. Below, you'll find the best vitamin C serums you can buy for your skin type, whether you have oily skin, want to boost collagen production, fight signs of aging or anything in between:
