Beta-Carotene and Mixed Carotenoids from Blakeslea Trispora: The Precursors to Vitamin A

Introduction to Beta-Carotene

Beta-carotene is a type of carotenoid, a pigment that is found in plants and is responsible for the orange, yellow, and red colors of many fruits and vegetables. It is a precursor to vitamin A, which means that it can be converted to vitamin A in the body. Beta-carotene is found in a variety of foods, including carrots, sweet potatoes, and leafy green vegetables, and is also available in supplement form (Hendrich et al., 1995).

Natural sources of beta-carotene

Beta-carotene is found in a variety of plant-based foods, including:

• Carrots: Carrots are a rich source of beta-carotene, with a cup of chopped carrots providing about 8 milligrams (mg) of beta-carotene.

• Sweet potatoes: Sweet potatoes are a good source of beta-carotene, with a single sweet potato providing about 4 mg of beta-carotene.

• Pumpkin: Pumpkin is a good source of beta-carotene, with a cup of cooked pumpkin providing about 4 mg of beta-carotene.

• Spinach: Spinach is a good source of beta-carotene, with a cup of cooked spinach providing about 3 mg of beta-carotene.

• Kale: Kale is a good source of beta-carotene, with a cup of cooked kale providing about 2 mg of beta-carotene.

It is worth noting that the amount of beta-carotene and mixed carotenoids you can obtain from food varies based on factors such as the soil in which it was grown, the processing methods used, the form in which it is present, and the presence of other substances that may interfere its absorption.

While dietary intake of beta-carotene and mixed carotenoids is important for maintaining adequate levels in the body, it is possible to obtain these nutrients with vitamin supplements. However, the best way to get the essential nutrients your body needs is to eat a variety of whole, unprocessed, fruits, vegetables, nuts, seeds, and other plant-based foods. These types of food ensure that you are getting a wide range of nutrients, which may include beta-carotene and mixed carotenoids, and should not be replaced by vitamin supplements alone.

Health Benefits of Beta-Carotene

There is a growing body of scientific evidence suggesting that beta-carotene may have numerous health benefits. Some of the potential benefits of beta-carotene include:

Antioxidant properties

Beta-carotene is a potent antioxidant, meaning that it can help to protect cells from damage caused by free radicals (Hertog et al., 1993). Free radicals are unstable molecules that can damage cells and are thought to play a role in the development of chronic diseases such as cancer and heart disease (Halliwell and Gutteridge, 2007).

Eye health

Beta-carotene has been shown to support eye health by helping to protect the retina, the light-sensitive tissue at the back of the eye (Landrum et al., 2001). It may also help to reduce the risk of age-related macular degeneration, a condition that can lead to vision loss (Seddon et al., 1994).

Skin health

Beta-carotene has been shown to improve the appearance of the skin and may help to reduce the risk of sunburn (Gonçalves et al., 2018). It may also have anti-aging properties and may help to reduce the appearance of fine lines and wrinkles (Flynn et al., 2018).

Immune function

Beta-carotene has been shown to support immune function and may help to reduce the risk of infections (Borel et al., 1997).

Beta-Carotene from Blakeslea Trispora as a Source of Mixed Carotenoids

Blakeslea trispora is a type of fungus that is known for producing a variety of carotenoids, including beta-carotene (Liesche et al., 2012). It has been studied as a potential source of mixed carotenoids, which are a group of plant pigments that are related to beta-carotene. These carotenoids include alpha-carotene, lutein, and zeaxanthin, which have been shown to have antioxidant and anti-inflammatory properties (Liesche et al., 2012).

Blakeslea trispora-derived mixed carotenoids have been shown to have a variety of potential health benefits. Some studies have suggested that they may have a protective effect against certain types of cancer, such as lung and breast cancer (Liesche et al., 2012; Neuhofer et al., 2015). They have also been shown to improve the appearance of the skin and may have anti-aging properties (Liesche et al., 2012).

What are the symptoms of beta-carotene deficiency?

Beta-carotene deficiency is rare, as beta-carotene is widely available in a variety of plant-based foods, including fruits, vegetables, and grains. Beta-carotene is also converted to vitamin A in the body, and most people get enough vitamin A from their diet.

However, people with conditions that interfere with the absorption of nutrients, such as Crohn's disease and celiac disease, may be at risk of beta-carotene deficiency. In these cases, supplements may be necessary to ensure adequate intake of beta carotene.

The symptoms of beta carotene deficiency may include:

• Dry, rough skin

• Dry, brittle hair

• Poor vision, especially in low light

• Decreased immune function

It is important to talk to your healthcare provider if you suspect that you may have a beta carotene deficiency. They can perform a blood test to check your beta carotene levels and recommend treatment options if necessary.

What are the potential side effects of taking beta-carotene?

Like any supplement, beta-carotene can cause side effects in some people. The most common side effects of taking beta-carotene supplements are skin changes, such as yellowing or orange discoloration of the skin or nails. This is because high doses of beta carotene can cause excess amounts of the substance to build up in the body, resulting in a condition called carotenemia.

Other potential side effects of taking beta carotene supplements include:

• Upset stomach

• Nausea

• Diarrhea

• Gas

In rare cases, beta carotene supplements have been linked to more serious side effects, including an increased risk of lung cancer in smokers and people who have been exposed to asbestos. However, these findings are not consistent and more research is needed to understand the potential risks of taking beta carotene supplements.

It's important to note that beta carotene is generally considered safe when taken in recommended doses. However, if you are considering taking beta carotene supplements, it's a good idea to talk to your health professional fifirst to discuss the potential risks and benefits.

It's important to note that vitamin A toxicity is more likely to occur from consuming too much preformed vitamin A, which is found in animal sources such as liver and fish oil, rather than from consuming too much beta-carotene, which is found in plant sources such as fruits and vegetables. Beta-carotene is converted to vitamin A as needed by the body, so it is difficult to consume too much of it.

Can beta-carotene supplements interact with other medications or supplements?

Beta carotene supplements can interact with certain medications and supplements, and can cause harmful effects if taken in combination with certain drugs. It is important to talk to your healthcare provider before taking beta carotene or any other supplements to ensure that they are safe and appropriate for you.

Some medications and supplements that can interact with beta carotene include:

• Retinoids: Beta carotene can interfere with the absorption and effectiveness of retinoids, such as isotretinoin and acitretin.

• Statins: Beta carotene can interfere with the absorption and effectiveness of statins, such as atorvastatin and simvastatin.

• Estrogens: Beta carotene can interfere with the absorption and effectiveness of estrogens, such as conjugated estrogens and ethinyl estradiol.

• Vitamin E: High doses of vitamin E can increase the risk of vitamin A toxicity.

It's important to inform your health professional about all medications and supplements you are taking, as they can help to identify any potential interactions. 

Is it safe to take beta-carotene supplements if I have a particular health condition?

It is generally safe to take beta-carotene supplements if you have a particular health condition, but it is important to consult with your healthcare provider before taking any supplements. Beta-carotene can interact with certain medications and supplements and can cause harmful effects if taken in combination with certain drugs.

If you have a particular health condition, your healthcare provider will consider your individual needs and determine the appropriate dosage and form of beta-carotene for you. They may also recommend alternative treatment options if they feel that beta-carotene is not suitable for you.

Some conditions that may be affected by beta-carotene intake include:

• Vitamin A deficiency: Beta-carotene is a precursor to vitamin A and supplements can be used to treat vitamin A deficiency. However, high doses of beta-carotene supplements can cause symptoms of vitamin A toxicity, including dry skin, hair loss, and liver damage.

• Skin conditions: Beta-carotene may be beneficial for certain skin conditions, such as eczema and psoriasis. However, more research is needed to confirm these findings.

• Cancer: Some research has suggested that beta-carotene may have cancer-protective effects, but more studies are needed to confirm these findings.

It is important to consult with your healthcare provider before taking beta-carotene or any other supplements if you have a particular health condition. They will be able to advise you on the appropriate dosage and form of beta-carotene for your individual needs.
