What is Beta Carotene?
Carotenoids are naturally occurring pigments found in plants that are responsible for imparting vibrant colors to fruits and vegetables. They are abundant in nature. It is estimated that there are 500 different carotenoids, including beta carotene, alpha-carotene, lutein, cryptoxanthin, and zeaxanthin, distributed throughout the plant and algae world.
- Beta Carotene is a derivation of the Latin name for carrot, as this compound was first derived from the carrot roots.
- It is an organic compound that is chemically classified as a hydrocarbon and specifically as a terpenoid.
- It is a strongly colored pigment that imparts the yellow and orange fruits and vegetables their rich hues. Once ingested, it gets converted into vitamin A (retinol) which performs several biological functions within the body. Vitamin A also acts as an antioxidant that protects cells from the damaging effects of harmful free radicals (1), (2)..
- Beta carotene and several other carotenoids are also known as “provitamin A” because they act as precursors to the production of vitamin A in the body.
- Other carotenoids like lycopene, lutein, and zeaxanthin cannot be converted into vitamin A.
- About 50% of vitamin A in a vegetarian diet is provided by beta carotene and other carotenoids. Beta-carotene is also produced synthetically or from palm oil, algae, and fungi.
- Vitamin A is involved in the formation of glycoproteins. It is essential for vision and is subsequently converted to retinoic acid which is used for processes such as growth and cell differentiation (3), (4).
Nutritional Value of Beta Carotene
When ingested into the body, beta carotene is converted to vitamin A (retinol) in the small intestines of mammals by beta-carotene 15 and 15 monooxygenase, an enzyme. Excess retinol is stored in the liver and synthesized into active vitamin A in times of need.
It is one of the most common forms of carotene and is fat-soluble but not water-soluble. To ensure its proper absorption, 3 to 5 grams of fat should be consumed (5). Carotenoids suspended in oil are more absorbable than those in water and food. According to the National Institutes of Health, the recommended intake of beta-carotene is 900 mcg RAE (Retinol Activity Equivalent) and 700 mcg RAE for adult males and females respectively.
Similarly, it recommends a dosage of 500 mcg RAE for infants of 7-12 months of age, 300 mcg RAE for children aged 1-3 years, 400 mcg RAE for children aged 4-8 years and 600 mcg RAE for children aged 9-13 years (6).
Carotenoid facilitates communication between cells by improving the expression of a gene that codes for connexin proteins. These proteins form pores or gap functions among cell membranes, thus allowing the cells to communicate through the exchange of small molecules (7).
Health Benefits Of Beta Carotene
The primary beta carotene benefits can be attributed to the fact that it is involved in the formation of vitamin A which is vital for maintaining healthy mucus membranes and skin. Some of beta carotene benefits are as follows.
1. Cardiovascular Health:
Taking a diet rich in beta carotene may reduce the risk of cardiovascular diseases to a significant extent (8). Animal studies suggest that beta carotene works with vitamin E to reduce the oxidation of LDL cholesterol, thus lowering the risk of atherosclerosisi XNarrowing of arteries due to a build-up of plaque containing cholesterol, fat, and other substances, in and on the walls of the arteries. and coronary heart disease (9).

Hence, dietary intake of beta carotene rich foods lowers the risk of breast, colon, oral cavity, and lung cancers (10), (11).
3. May Be Good for the Brain
Research suggests that consumption of carotenoids such as beta carotene may significantly delay cognitive aging. Moreover, it may fight oxidative stress that can damage brain cells over time, thus reducing the risk of dementia and improving cognitive function (12).
4. May Help In The Treatment of Respiratory Ailments
High intake of beta carotene foods may help increase lung capacity and relieve the symptoms of respiratory ailments, thus helping improve breathing disorders like asthma, bronchitis, and emphysemai XA chronic lung condition that results in damaged, weakened, and ruptured air sacs (alveoli) in the lungs, thereby causing shortness of breath. (13). Animal studies also have shown the same effect (14).
