Taking vitamin C can increase cortisol levels, but the effect is likely to be mild and short-lived. Cortisol is a hormone produced by the body's adrenal glands in response to stress. It helps the body respond to threats by increasing energy levels and preparing the body for fight-or-flight responses. Taking vitamin C can cause the adrenal glands to produce more cortisol, resulting in a temporary increase in cortisol levels.
The effect of vitamin C on cortisol levels can vary depending on the amount of vitamin C taken. Generally, taking a supplement that contains 500-1000mg of vitamin C can lead to a small increase in cortisol levels. Higher doses of vitamin C may lead to a more significant increase in cortisol levels. It should be noted that this effect is likely to be short-lived, and levels of cortisol will return to normal once the vitamin C is metabolized.
It is important to note that increased cortisol levels can have both positive and negative effects on the body. In the short-term, cortisol can help the body respond to stress more effectively. However, long-term elevated cortisol levels can lead to a variety of issues such as weight gain, depression, and immune system dysfunction. Therefore, it is important to make sure that any increase in cortisol levels due to vitamin C supplementation is only temporary. Additionally, it is important to consult with a healthcare professional before taking any supplements.
