FAQ
Frequently Asked Questions
No. Carotene (specifically beta-carotene) is a 'provitamin A carotenoid'. This means it is a precursor that the body converts into active vitamin A (retinol). They are related but distinct compounds.
Foods with deep orange, yellow, red, or dark green colouring are typically high in carotenes. Excellent sources include sweet potatoes, carrots, pumpkins, spinach, kale, cantaloupe, and red peppers.
Excessive consumption of carotene from food is not toxic, as the body regulates its conversion to vitamin A. However, it can cause a harmless condition called carotenemia, where the skin turns slightly orange. High-dose supplements are a different matter and can pose risks.
Carotene is vital because it is a major source of vitamin A for many people, especially where animal sources (like liver) are not commonly consumed. Vitamin A is essential for good vision, a healthy immune system, and proper cell growth.
