Beta-carotene benefits -

The benefits of beta carotene for hair are just as noteworthy, keeping our locks as luxe as can be. Are you noticing a few too many stray hairs on your brush or down the shower drain? Beta carotene aids in cell regrowth, which can help combat hair thinning.

A tried and true overachiever, beta carotene also gets to the root of hair health, promoting the maintenance and development of your scalp skin and follicles. The result? Increased moisture and shine. Beta carotene can help with that. Research suggests that beta carotene may prevent eye diseases and damage, potentially lowering the risk of cataract development.

As an antioxidant, beta carotene performs a crucial dual function: it protects the lens and retina from damage due to light exposure and reduces oxidative stress , which can cause a host of cognitive problems as well as age-related vision loss.

Maintaining balanced beta carotene levels is sometimes as simple as a quick trip to the produce aisle. A wide range of delicious fruits and veggies boast high levels of this health-supporting nutrient. Aim to eat the rainbow. As a general rule, the more colorful the piece of produce, the more beta-carotene it contains.

Some of these vibrant, nutritious vegetable and fruit ingredients include:. As if you need more salad inspiration, experts suggest eating beta-carotene-rich foods and ingredients with healthy fats, like avocado or extra virgin olive oil, to improve absorption.

We could go on for ages about the potential health benefits of beta carotene and vitamin A for skin health, hair growth, and organ function. Care to learn more about beta carotene?

What is Beta-Carotene? Commercially available supplements typically contain between 1. Supplements should be used short-term under the direction of your health care provider. Possible side effects from this carotenoid include headache, burping, loose stools, bruising, joint pain and yellowing skin, although the discoloration eventually goes away.

People who smoke or drink heavily should avoid taking this carotenoid. Studies show that it causes an increased risk of cancer. People with a history of exposure to asbestos should also avoid using beta-carotene supplements because they may increase the risk of liver disorder or heart disease.

Tell your doctor if you take beta-carotene supplements while taking cholesterol-lowing drugs, antibiotics, proton pump inhibitors, or listat or plant sterols.

Beta-carotene benefits -

In fact, doing so could cause more harm than good, according to the U. Preventive Services Task Force , an independent panel of experts in disease prevention and evidence-based medicine.

AARP Membership. Get instant access to members-only products and hundreds of discounts, a free second membership, and a subscription to AARP The Magazine. Join Now. More than half of U. When you ingest it, the body can convert beta-carotene into vitamin A, which is important for vision, immune function, and growth and development.

Vitamin A also supports the heart, lungs and other organs. Vitamin A deficiency is rare in the U. People with cystic fibrosis are also at increased risk of vitamin A deficiency. Nevertheless, up to about 40 percent of the U. population uses supplements containing vitamin A, and older adults are more likely to take it than their younger peers, research shows.

Target Optical. Beta-carotene is an antioxidant, which is a substance that can prevent or slow cell damage. And some studies have even shown a counterproductive effect, where high doses of beta-carotene supplements are linked to an increased risk of lung cancer and death in smokers and people who have been exposed to asbestos.

Supplementation with the nutrient has also been associated with an increased risk for cardiovascular disease. One sign that you could need more beta-carotene is if you start experiencing difficulty seeing well in the dark but still see just fine in the light.

Other warning signs that you are lacking in vitamin A include dry eyes, eye infections, skin problems and slowed growth, according to Mayo Clinic.

There is no recommended daily allowance for beta-carotene, but adults should eat five or more servings of fruits and vegetables every day to get about 3 to 6 milligrams mg of beta-carotene, the experts at Mount Sinai say.

One sweet potato contains about 11 mg of beta-carotene; so does a cup of raw chopped carrots. Leafy greens kale, spinach, broccoli are also a great source of beta-carotene, says Candy Tsourounis, a pharmacist, professor and supplements expert at the University of California San Francisco School of Pharmacy.

And the feeling of being full will kick in before you can consume too much of any one vitamin or mineral, Taioli adds.

Small supplements, on the other hand, can be particularly potent. Tsourounis sees this all the time, especially among older adults. One study published in The Journal of Nutrition found that almost 30 percent of older adults in the U.

take four or more supplements. But since the body converts only as much vitamin A from beta-carotene as it needs, beta-carotene supplementation comes with fewer potential side effects , like yellowing of the skin, dizziness, diarrhea and joint pain. Beta-carotene supplements can also interact with a few medications , including some statins and some cholesterol-lowering drugs, as well as the weight-loss drug orlistat Alli, Xenical.

Rachel Nania is an award-winning health editor and writer at AARP. org, who covers a range of topics including diseases and treatments. Oxidative stress is thought to be a key factor in cognitive decline, the researchers explained.

Studies have shown that antioxidant supplements may help prevent the deterioration of cognition. Their study, involving 4, men, compared those on beta carotene supplements for an average of 18 years to others who were given placebo.

Over the short-term, they found no difference in cognitive decline risk between the two groups of men, but in the long-term it was clear that beta carotene supplements made a significant difference. The researchers emphasized that there may have been other factors which contributed to the slower decline in cognitive abilities among the men in the beta carotene group.

The BMJ published a report in March which showed that high blood beta carotene levels compensate for some of the damage to the lungs caused by oxygen free radicals.

They measured the FEV1 of participants and measured their beta carotene blood levels. FEV1 measures how much air you can breathe out in one go. They found that those with high beta carotene levels had much slower decline in FEV1 measures. If you follow a healthy diet rich in beta carotene you do not need supplements.

As mentioned above, supplements can lead to undesirable excesses in beta carotene levels — this cannot occur if your source is from the food you eat. A French study involving adult females published in the Journal of the National Cancer Institute September issue found that smokers with high beta carotene levels had a higher risk of lung cancer and other smoking-related cancers than other smokers.

They also found that non-smokers with high beta carotene intake had a lower risk of lung cancer. Further research has suggested that the high intake among smokers is nearly always due to supplements, and not food intake.

Drug interaction refers to a substance interfering in how a medication works, by either making it less effective, increasing its potency, or changing what it is supposed to do.

Long-term alcohol consumption can interact with beta carotene, raising the chances of developing liver problems. Beta carotene supplements are available for purchase online.

Speak to a doctor before taking new supplements. Usually, the body turns beta carotene into vitamin A, but not always. New studies in mice and humans investigate what this means for health. Arugula is healthful, cruciferous leafy green with a peppery taste.

Published July 01, Join AARP. The link between beta-carotene and cancer. View Details. Another older study, published in , had similar results: 71 percent of patients in the treatment group had major responses to 30 milligrams of beta-carotene per day.

Researchers concluded that because of its lack of toxicity, it serves as an excellent candidate as a preventive agent for oral cancer. Research published in the European Respiratory Journal suggests that eating fruits with beta-carotene can improve respiratory and pulmonary function.

In comparison with eating fruit rarely or never, people who ate fruit at least once a day had reduced respiratory symptoms, such as phlegm production, shortness of breath and wheezing. Fruits of any kind help fight respiratory conditions, including mango , papaya and cantaloupe.

Because beta-carotene works as an antioxidant, it may fight oxidative stress that contributes to brain aging and reduce the risk of cognitive decline. Although the evidence on this potential benefit is mixed, one study found that long-term supplementation with the antioxidant may provide cognitive benefits.

Instead, long-term consumption of colorful fruits and vegetables is the best way to prevent early cognitive decline and ensure that you get the nutrients necessary for proper brain function.

There have been studies suggesting that lung cancer, particularly in smokers, and cardiovascular disease may actually be enhanced by supplemental beta-carotene. A meta-analysis published in the International Journal of Cancer supports findings of an increased risk of lung and stomach cancers in smokers and asbestos workers who supplemented with 20 to 30 milligrams of beta-carotene per day.

For this reason, researchers believe that beta-carotene supplements should not be recommended for primary cancer prevention. However, a study conducted at Yale University School of Medicine in found that high fruit and vegetable consumption, particularly a diet rich in carotenoids, reduced the risk of lung cancer.

Researchers at Cleveland Clinic conducted a meta-analysis, combining the results of eight studies on the effects of beta-carotene at doses ranging from 15 to 50 milligrams. After investigating data from over , patients, researchers found that supplementation led to a small but significant increase in cardiovascular death.

Even though the supplements did not prove beneficial in avoiding heart problems, studies show that antioxidant foods should still be recommended.

Numerous observational studies have found that people who ingest more carotenoids in their diets have a reduced risk of several chronic diseases. The richest sources of beta-carotene are yellow and orange fruits and vegetables, plus leafy green vegetables.

The chlorophyll in leafy greens hides the yellow-orange pigment. In general, the brighter and more intense the color, the more beta-carotene is present in that food. The American Heart Association recommends getting enough beta-carotene from a diet high in fruits and vegetables, rather than through supplements.

To get about six to eight milligrams a day, eat five or more servings of fruits and vegetables, especially these foods:. Beta-carotene is fat-soluble, so you need to consume fats in order for it to be absorbed properly. You can do this by cooking vegetables containing this carotenoid in coconut oil or olive oil, which also have numerous health benefits.

Commercially available supplements typically contain between 1. Supplements should be used short-term under the direction of your health care provider.

Benefits Of Beta Carotene For Skin, Hair & Overall Health – Clean Program

Vitamin A foods can help boost your immune system, protect your skin and eyes, and fight life-threatening conditions like heart disease and cancer. Beta-carotene is a pigment found in plants that gives yellow and orange fruits and vegetables their color.

Vitamin A is found in two primary forms: active vitamin A and beta-carotene. Active vitamin A is called retinol, and it comes from animal-derived foods. This preformed vitamin A can be used directly by the body without needing to convert the vitamin first. Evidence reveals that eating high-antioxidant foods that contain beta-carotene is good for your health and may help prevent serious conditions.

In fact, some studies even suggest that supplementation may increase your risk of serious health conditions like cancer and heart disease. Beta-carotene and other carotenoids have antioxidant activities and are valued for their ability to prevent chronic disease.

They protect cells from damaging free radicals, which are the primary cause of aging and degeneration. Studies have shown an inverse relationship between the presence of various cancers and dietary carotenoids or blood carotenoid levels.

However, it appears that carotenoids can promote health when taken at dietary levels but may have adverse effects when taken in high doses by people who smoke or who have been exposed to asbestos.

Researchers are still determining the proper doses for carotenoids to be beneficial and not dangerous. The American Pediatrics Association cites vitamin A as one of the most critical vitamins during a pregnancy diet and while breastfeeding. Vitamin A plays an important role in the healthy development of the fetus and the newborn, with lung development and maturation being particularly important.

Research published in the European Journal of Nutrition notes that there should be a 40 percent increase in vitamin A intake for pregnant women and a 90 percent increase for breastfeeding women. If you do need a supplement to get enough this carotenoid, use it under the supervision of your health care provider.

Protects the Skin Ad. Beta-carotene metabolism takes place in a wide variety of organs, including the skin. Many studies have found that it helps prevent the formation of UV-induced erythema, or skin irritation and redness. Beta-carotene and other antioxidants may help delay the progression or reduce the risk of age-related macular degeneration, which causes vision changes that are sometimes so severe that irreversible legal blindness can occur.

The Age-Related Eye Disease Study established that a combination of dietary antioxidants, including eye vitamins zinc, beta-carotene, vitamin C and vitamin E, effectively slowed the progression of macular degeneration. A study conducted at the University of Arizona confirmed the efficacy of beta-carotene in patients with oral leukoplakia, which is highlighted by thickened, white patches that form on your gums and inside your cheeks.

Most leukoplakia patches are benign, but some may be early signs of cancer. Fifty patients were given 60 milligrams of beta-carotene a day for six months, and then participants were chosen to either continue treatment or use placebo therapy for 12 additional months.

The results showed that 52 percent 26 patients of the participants had a clinical response to treatment, and 23 of the 26 patients who responded positively completed the second, randomized phase of the study. Another older study, published in , had similar results: 71 percent of patients in the treatment group had major responses to 30 milligrams of beta-carotene per day.

Researchers concluded that because of its lack of toxicity, it serves as an excellent candidate as a preventive agent for oral cancer. Beta carotene is an antioxidant.

There are many types of antioxidants, including both artificial and natural. Natural antioxidants can be found in plants. Antioxidants are thought to slow the damage to cells from waste materials called free radicals.

Free radicals are created in the body through normal body processes and outside stress in the environment. Oxidative stress may factor into several types of health conditions, including:. Antioxidants like beta carotene may help remove free radicals, thereby preventing the conditions free radicals may cause.

Vitamin A is important to sight. It helps prevent eye infections by supporting the creation of a barrier around the cornea that stops bacteria from getting in. Beta carotene helps in preventing night blindness and dry eye. It may play a role in preventing age-related macular degeneration AMD.

AMD is an eye condition that causes blurry vision, most commonly in people over the age of Vitamin A deficiency might lead to night blindness nyctalopia , which is a difficulty in seeing in low-light conditions.

Increasing vitamin A or beta carotene with either supplements or through foods may be helpful. Beta carotene may help with brain function, but the research on this is not settled. Some studies have shown that taking beta carotene supplements over an average of 18 years might improve cognitive function.

Taking the supplements for shorter time periods does not appear to produce any effects. Beta carotene may help in protecting the skin from the sun's harmful rays. However, this requires taking beta carotene in higher amounts for a long period of time. The exception would be for people who have diseases that are affected significantly by exposure to the sun such as erythropoietic protoporphyria or who are taking medications that cause sun sensitivity.

Beta carotene and other carotenoids may also help keep skin healthy overall by protecting it from ultraviolet UV light and pollution. Because UV light exposure and pollution can cause the skin to age, sun protection, including from the benefits of carotenoids, can keep skin healthy and looking younger longer.

A diet rich in foods containing antioxidants like beta carotene may help lower cancer rates. Some studies show that people who eat foods containing beta carotene or who have higher levels of beta carotene in their blood have lower rates of lung, skin , colon , breast , and prostate cancers. However, the relationship between beta carotene and cancer is not cut-and-dried.

Experts have not recommended beta carotene supplements to the general populace as they don't think it would help prevent many cases of cancer. The way beta carotene interacts with the body is too complex and not yet well understood.

Vitamin A is important in the healthy function of the lungs. Vitamin A deficiency may be a factor in the development or worsening of some lung diseases.

For that reason, getting enough beta carotene, which becomes vitamin A in the body, is important to the lungs. However, there is another side to the story. Studies have shown that taking beta carotene supplements increases the risk of lung cancer in people who smoke cigarettes. Many fruits and vegetables that are red, yellow, or orange have high amounts of beta carotene.

However, some green foods are also good sources. Some of the foods that are sources of beta carotene include:. Some medical professionals recommend about 2 milligrams of beta carotene daily.

The highest amount considered safe is about 7 milligrams daily. However, beta carotene supplements are not currently recommended for general use. Getting enough beta carotene through food rather than a supplement is always recommended.

Higher doses of beta carotene may be recommended, but this should only be done under the recommendation and supervision of a healthcare provider.

Taking beta carotene supplements in high doses could make the skin appear yellow or orange carotenemia. Higher doses are also associated with the risk of some cancers. This is especially true in people who are at higher risk of cancer after exposure to asbestos or for those who smoke.

Getting beta carotene through food sources, which is recommended, has not been shown to have the same risk of side effects as taking supplements has. Beta carotene supplements may interact with niacin , lutein , and Xenical or Alli orlistat.

The amount of beta carotene in the body may be lowered in those who drink more than a moderate amount of alcohol or eat foods containing olestra a fat substitute.

If your healthcare provider recommends supplementing with beta carotene, look for the following in a supplement:. Beta carotene is important to overall health because it is the precursor to vitamin A.

However, taking supplements is not recommended for the majority of people. Instead, people are encouraged to eat foods that contain beta carotene. There are some reasons people might take a supplement, but these are not common and it would only be done with the guidance of a healthcare provider.

Beta carotene is not the same as vitamin A. It is called "provitamin A. Beta carotene from foods is an important part of a healthy diet. The body converts beta carotene into vitamin A, which is an essential vitamin.

In this article, we explain all about beta carotene, what it does in the body, and what foods it is found in. We will also cover any associated risks. The human body converts beta carotene into vitamin A retinol — beta carotene is a precursor of vitamin A.

We need vitamin A for healthy skin and mucus membranes, our immune system, and good eye health and vision. Beta carotene in itself is not an essential nutrient, but vitamin A is. Vitamin A can be sourced from the food we eat, through beta carotene, for example, or in supplement form.

The advantage of dietary beta carotene is that the body only converts as much as it needs. Excess vitamin A is toxic. Toxic vitamin A levels can occur if you consume too many supplements. There are a number of ways that beta carotene can benefit human health. Below, we give some examples:.

Beta carotene, like all carotenoids, is an antioxidant. An antioxidant is a substance that inhibits the oxidation of other molecules; it protects the body from free radicals. Free radicals damage cells through oxidation. Eventually, the damage caused by free radicals can cause several chronic illnesses.

Men who have been taking beta carotene supplements for 15 or more years are considerably less likely to experience cognitive decline than other males, researchers from Harvard Medical School reported in Archives of Internal Medicine November issue.

Oxidative stress is thought to be a key factor in cognitive decline, the researchers explained. Studies have shown that antioxidant supplements may help prevent the deterioration of cognition. Their study, involving 4, men, compared those on beta carotene supplements for an average of 18 years to others who were given placebo.

Over the short-term, they found no difference in cognitive decline risk between the two groups of men, but in the long-term it was clear that beta carotene supplements made a significant difference. The researchers emphasized that there may have been other factors which contributed to the slower decline in cognitive abilities among the men in the beta carotene group.

The BMJ published a report in March which showed that high blood beta carotene levels compensate for some of the damage to the lungs caused by oxygen free radicals.

They measured the FEV1 of participants and measured their beta carotene blood levels. FEV1 measures how much air you can breathe out in one go.

They found that those with high beta carotene levels had much slower decline in FEV1 measures. If you follow a healthy diet rich in beta carotene you do not need supplements. As mentioned above, supplements can lead to undesirable excesses in beta carotene levels — this cannot occur if your source is from the food you eat.
