Care to learn more about beta carotene? What is Beta-Carotene? How to Maintain Balanced Beta Carotene Levels Maintaining balanced beta carotene levels is sometimes as simple as a quick trip to the produce aisle. Some of these vibrant, nutritious vegetable and fruit ingredients include: Carrots Persimmons Winter squash Spinach Broccoli Kale Tomatoes Apricots Cantaloupe 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.

Evidence-Based Benefits of Beta Carotene 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.

And, by protecting against UV exposure and oxidative stress, this antioxidant can mitigate the risk of skin-related conditions. One study suggests that vitamin A and beta carotene intake might be inversely related to cataract risk.

Studies show that beta-carotene promotes our scalp health, too. Retinoic acid, which derives from vitamin A, plays a central role in the development and maintenance of scalp tissues and hair follicles, which can impact the strength and shine of our hair.

It is possible that beta-carotene supplementation might have an effect on health in a population that is under greater physiological health stress or greater dietary restrictions than our sample.

From a life-history perspective, physiological trade-offs are more apparent when individual or environmental conditions are limiting Stearns Our participants were all relatively healthy individuals recruited from a university community.

It is possible that we found an effect of beta-carotene on facial appearance but not health because the participants simply did not require additional carotenoids to support their health and devoted all the supplemented beta-carotene to appearance. It would be informative for future studies to examine a population that is under greater physiological or dietary stress.

Although we did not find a significant effect of beta-carotene on any of our health measures, carotenoids could still be linked to health via indirect mechanisms. For example, Hartley and Kennedy postulated that carotenoid coloration might actually signal the presence of other antioxidants that protect carotenoids from oxidative damage, which would otherwise cause carotenoids to lose their color i.

This hypothesis is also known as the carotenoid protection hypothesis. In support of this hypothesis, experimental studies have found that dietary supplementation of nonpigmentary antioxidants increase carotenoid-based coloration in species such as zebra finches, Taeniopygia guttata Bertrand et al.

It would be interesting to examine the carotenoid protection hypothesis in humans by investigating the effect of consuming nonpigmentary antioxidants on skin yellowness and redness.

Another possibility is that carotenoids only affect health when they are paired with other nutrients. Almbro et al. They argued that because vitamin E is converted to radical species when it is used as an antioxidant, beta-carotene might serve to recycle the radicalized vitamin E, thus enhancing overall antioxidant status.

Therefore, a potential future direction would be to examine whether beta-carotene affects health in humans when paired with vitamin E. In most species, carotenoid-based coloration is sexually selected via female mate choice for male carotenoid ornamentation, and most species show sexual dimorphism in carotenoid coloration.

A recent study reported that human skin color is also sexually dimorphic Carrito et al. However, mate selection in humans occurs in both directions and carotenoids influence appearance in both sexes Stephen et al.

Therefore, it would be interesting to see the extent to which our findings could be replicated in women.

It would also be interesting for future studies to examine whether beta-carotene influences health over a longer supplementation period. We chose the week duration partly because spermatogenesis plus epididymal transit in humans takes a total of 82 days ~ Therefore, we should have been able to observe any effects of beta-carotene on semen quality after 12 weeks of supplementation.

Previous studies examining the effects of antioxidant supplementation on semen quality and oxidative stress have used similar supplementation durations Møller and Loft ; Showell et al.

However, it remains possible that we might observe significant effects of beta-carotene on health in a relatively healthy population like the one in the present study with a longer supplementation duration.

Zareba et al. Given this finding, it would be interesting to examine the long-term effect of beta-carotene supplementation on health by repeating the present study with a supplementation period of 1 year or more.

In summary, we report the first double-blind, placebo-controlled experimental study on the effect of carotenoids on human facial appearance and health. We found that beta-carotene alters skin color by enhancing yellowness and redness to enhance facial attractiveness in human males.

However, we found no evidence that carotenoids improve actual health. Together, our results suggest that carotenoid-based coloration may have been sexually selected in humans, but we have no evidence to suggest that it is an honest signal of health.

Beta-Carotene Supplements [Not Recommended] - Here's Why

Beta-carotene for skin -

Beta-carotene supplementation has also been reported to alleviate the symptoms of photosensitization and has a mild sun screen effect.

DSM said that the beta-carotene had to be taken orally as a supplement in order to exert its photo protective effects in skin. The report also revealed that Europe's health food industry had 'under-utilised' the nutraceutical properties of carotenoids and consumers are still unaware of their health benefits.

You can learn more about acne, with its causes and treatments, here. Now we come to the crux of the question in the title of this article: what is the difference between all the names for vitamin A in skin care?

Their end goal at least in your skin is to oxidize until they become retinoic acid i. Retinoic acid is what your skin can use to renew itself. Another side note: you know when people say that eating too many carrots can turn your skin orange? Vitamin A is naturally orange, red or yellow in colour.

In the first generation they are: retinol, retinal, tretinoin e. brand name Retin-A , isotretinoin e. brand name Accutane , and alitretinoin. In the third generation they are adapalene e.

brand name Differin , bexarotene e. brand name Targretin , and tazarotene e. brand name Avage. The first generation of retinoids perform particularly well in the body, and in the skin, to become retinoic acid.

This is why you often hear these terms spoken of by cosmetic aficionados. The same can be true for all generations, however. They can be prescribed for different skin needs.

At that point, the body turns them into retinol, with varying numbers of steps. Eventually, they morph into retinaldehyde before becoming retinoic acid. All of the above esters can be found in skin care products.

So, they are selected for particular strengths by cosmetic chemists. This is a pertinent question. The thing is, retinoic acid is very strong stuff. In fact, even over-the-counter retinol is quite strong. Most people who use this vitamin for skin care can experience dryness, peeling and redness even if they start with oily, acneic skin.

It is very uncomfortable to use at first. Though, eventually the skin gets used to it for most people. Retinoids, in their stronger forms, and in higher concentrations, are only allowed to be sold with prescriptions in countries that regulate them, like Canada.

Pregnant women should not use them — not even topically. Oral Accutane isotretinoin can cause long-term side-effects throughout the body. But of course, there are many benefits to using gentler, over-the-counter versions of retinoids for the average, everyday person. This is possible mainly with retinol.

People with sensitive skin may not be able to tolerate them at all. So, cosmetic researchers have come up with all kinds of ways to reduce irritation caused by retinol in skin care.

These attempts have included:. For example, one synthetic form of retinol which also undergoes steps to become retinoic acid, is retinyl retinoate. It is purposely designed to oxidize slower, so that it can be less irritating to the skin. In another example, retinoic acid can be mixed with a vitamin C ester to become retinyl ascorbate.

Our favourite adaptation would be encapsulated retinol. Specifically, at our clinic, we sell Retinol Complex 1, 0.

What is encapsulated retinol? The coating allows for two main actions:. These coatings can include moisturizers or antioxidants, like in the case with SkinMedica® retinol. When it comes to retinol and not other forms of retinoids , almost anyone can benefit from this ingredient.

That is, as long as they can tolerate its strength, and are diligent to wear high SPF sunscreen every day. This also applies to retinyl esters. On your next product hunt, test a higher concentration, and again, gradually increase application until your skin is used to it.

Our advice is to look for a retinol product that combines the benefits of other ingredients to reduce irritation while remaining effective, such as the encapsulated retinol by SkinMedica® mentioned above. The product should also be free of irritants such as fragrances, drying alcohols or ingredients that attempt to further exfoliate the skin, such as alpha-hydroxy acids.

Now, when it comes to other retinoids , including prescription-strength retinol, the way to find out the best one for you , is to speak with your doctor.

These are all available by prescription in North America with the exception of a low-strength adapalene which is available over the counter in the U. Even if you think you need a mild strength of a prescription retinoid, a doctor will need to clear it first. Most people who are prescribed such strong versions of retinoids may have extreme skin conditions that require them.

They may have more potential side-effects. But, whether the benefits outweigh their cons will be something for you and your doctor to determine. So, they are not like ingesting vitamin A supplements, which you can have too much of. Now, it is important to be warned that vitamin A derivatives, like retinol and its esters, can make you sensitive to UV light.

UV light exposure leads to free radical damage , which can — eventually — lead to skin cancers. For that reason, vitamin A skin products should only be used at night. They should also be followed by the use of an SPF 30 or higher during the day.

On the flip side, when used appropriately, vitamin A can help to remove precancerous, sun-damaged cells from your body. Human skin is complex; it needs many antioxidants , growth factors , proteins, fats and hydrators among other things to supplement its ability to function and look good.

No doubt, the skin care industry offers plenty of options for wrinkles and anti-aging needs. Acne is another big category where the skin care industry thrives. We can all be thankful for the dedicated scientists, doctors and cosmetic chemists who put these formulations together for us in stable, effective and easy-to-use products.

Not to mention, keep them up-to-date.

This article will cover the current research and understanding of how beta carotene affects the body and which foods are good sources of this antioxidant. Carotenoids are a group of yellow, orange, or red pigments. They can be found in fruits, vegetables, fungi, and flowers, among other living things.
