What is beta-carotene?

Beta-carotene is a natural pigment from the carotenoid group that gives carrots, pumpkin, apricots and many other fruits and vegetables their distinctive yellow-orange color. There are about 700 different carotenoids in nature, and some of them play a significant role in human health.

The most important carotenoids present in human plasma are beta-carotene, lycopene and lutein. Beta-carotene attracts particular attention due to its ability to be converted by the body into vitamin A – a nutrient crucial for eyesight, immunity and skin health.

The name beta-carotene comes from the Latin word “carota”, which means carrot, because it was from the carrot that it was first isolated.

The relationship between beta-carotene and vitamin A

Beta-carotene as a natural source of vitamin A

Beta-carotene is known as provitamin A, which means that the body converts it into vitamin A according to its own needs. This process takes place mostly in the liver.

Unlike synthetic vitamin A, with beta-carotene the risk of overdose is significantly lower, because the body only produces as much vitamin A as it needs.

Vitamin A plays an important role in:

• maintenance of normal vision,
• proper functioning of the immune system,
• cell renewal,
• skin and mucous membrane health.

Benefits of beta-carotene

Powerful antioxidant effect

Protection against free radicals and aging

Beta-carotene is a strong antioxidant. Antioxidants neutralize free radicals – unstable molecules that can damage cells and accelerate the aging process.

Modern research shows that oxidative stress is associated with:

• cardiovascular diseases,
• chronic inflammations,
• diabetes
• neurodegenerative diseases,
• certain types of cancer.

Regular intake of foods rich in carotenoids can help protect cells and support immunity. Beta-carotene also participates in the synthesis of antibodies, which additionally contributes to a better defense of the body.

Beta-carotene for better vision

How does it affect eye health?

The advice “eat carrots for better eyesight” has a scientific basis. Beta-carotene is necessary for the production of vitamin A, which is crucial for the normal functioning of the retina.

Vitamin A deficiency can cause:

• night blindness,
• dry eyes,
• reduced visual acuity.

Research published in recent years suggests that carotenoids may have a protective effect on age-related macular degeneration (AMD) – one of the most common causes of vision loss in people over 50.

A 2016 study found that a higher intake of carotenoids was associated with a reduced risk of macular degeneration, while additional analysis from 2017 confirmed that a diet rich in beta-carotene, alpha-carotene and vitamin c positively affects eye health.

Beta-carotene for skin and a beautiful complexion

Natural sun protection

Beta-carotene is also popular because of its positive effect on the skin. In the body, it contributes to the creation of vitamin A, which is important for the regeneration of skin cells.

Additionally, beta-carotene:

• supports the creation of collagen,
• contributes to skin elasticity,
• helps with an even complexion,
• may reduce the skin’s sensitivity to the sun.

For many people, especially in early summer, sun exposure causes redness, itching and rashes. Some research shows that carotenoids can help with the skin’s natural photoprotection.

However, it is important to emphasize that beta-carotene is not a substitute for an SPF cream.

Impact on cognitive functions

Can beta-carotene help the brain?

Oxidative stress also plays a significant role in brain aging. Due to its antioxidant effect, beta-carotene is also being researched in the field of cognitive health.

A review of multiple studies published in 2018 found that long-term intake of antioxidants can help slow cognitive decline and support memory in the elderly.

Although further research is needed, scientists believe that antioxidants play an important role in protecting nerve cells.

Beta-carotene and cardiovascular health

Potential protection for the heart and blood vessels

Some scientific research suggests that a diet rich in carotenoids is associated with a lower risk of atherosclerosis and heart disease.

Beta-carotene can help by:

• reduction of oxidative stress,
• improving the function of blood vessels,
• reduction of inflammatory processes.

Studies conducted in several countries have shown that populations that regularly consume fruits and vegetables rich in carotenoids have lower rates of certain chronic diseases.

However, experts emphasize that the greatest effect is achieved through a varied and balanced diet, and not through excessive use of supplements.

Other potential benefits of beta-carotene

Research on beta-carotene continues, and the results so far indicate possible positive effects in:

Type 2 diabetes

A diet rich in carotenoids is associated with better insulin sensitivity and a lower risk of developing type 2 diabetes.

cholesterol reduction

Some studies show that beta-carotene can affect the reduced absorption of cholesterol in the intestine.

Slowing down atherosclerosis

Carotenoids can contribute to the reduction of fat deposition in blood vessels.

Best natural sources of beta-carotene

Foods rich in beta-carotene

The best way to get beta-carotene is through a varied diet.

Foods rich in beta-carotene:

• carrot,
• sweet potato,
• pumpkin,
• apricots,
• peaches,
• spinach,
• kale,
• broccoli,
• red pepper.

Beta-carotene is better absorbed when vegetables are combined with healthy fats, such as olive oil, nuts or avocados.

Should it be taken as a supplement?

When is additional supplementation needed?

In most cases, a balanced diet provides sufficient amounts of beta-carotene. However, supplements are sometimes used:

• in people with insufficient intake of fruits and vegetables,
• to prepare the skin before summer,
• in people with increased needs for vitamin A.

It is important to use the supplements carefully, especially in smokers, as high doses of synthetic beta-carotene have been linked to an increased risk of lung disease in some studies.

Beta-carotene is an important antioxidant with a significant role in the health of the eyes, skin, immunity and cardiovascular system. The greatest benefits are obtained through regular consumption of fruits and vegetables rich in carotenoids.

Although scientific research continues to examine all of its effects, current knowledge confirms that beta-carotene is an important part of a healthy and balanced diet.
