AKA - Retinol, Retinoic Acid, Retinyl, Beta Carotene - what’s the difference?
In this 2 part series, Ali (@empoweredautoimmune) and I will be exploring the fundamental roles of Vitamin A.
☘️🐔PLANTS VS ANIMALS:
Vitamin A is obtained through the diet in two forms. Preformed vitamin A (retinol and retinyl ester) is derived from animal sources such as organ meat, dairy products, and some fish.
Provitamin A (beta-carotenoid) is derived from colorful fruits and vegetables. Both ingested forms of vitamin A must be converted to retinal and retinoic acid after absorption to support biologic processes (Chea et al., 2018).
⚤SUPPORTS SEX HORMONES:
The body requires cholesterol, vitamin A and red light (think sun), in order to make the first protective anti-stress and anti-aging hormone, pregnenolone (Peat, 2019). From pregnenolone, progesterone, DHEA and cortisol are made, all hormones which are crucial to the body’s resistance to stress and aging.
🔥INCREASES BROWN FAT?!
Treatment with Vitamin A reduces body weight and fat levels independently of changes in food intake and improves insulin sensitivity and glucose tolerance in both lean and obese mice, via increasing brown fat (Amengual et al., 2018).
Vitamin A lowers TSH and increases T3 in both lean and obese humans. Obese individuals are oftentimes hypothyroid, underscoring the positive effects of vitamin A on thyroid function even in the context of compromised metabolism and health (Farhangi et al., 2012).
