Which vitamin is also described as the missing stress hormone?

Vitamin C is often referred to as the "missing stress hormone" due to its vital role in the body's response to stress. This vitamin is essential for the production of adrenal hormones, particularly cortisol, which is a key hormone that helps the body respond to stress. When you're under stress, your body requires more vitamin C to support the increased production of cortisol and other stress-related hormones.

Additionally, vitamin C helps to maintain healthy levels of neurotransmitters in the brain, which play a significant role in mood regulation and emotional resilience. Because of its impact on adrenal function and its ability to combat oxidative stress, vitamin C is crucial for overall health, particularly during periods of stress.

The other options, while important for various bodily functions, do not have the same direct connection to stress response and hormone production as vitamin C does. Vitamin B12 and B6 are important for energy metabolism and neurological function, while biotin plays a role in macronutrient metabolism, but neither directly addresses the relationship between vitamin C and stress hormone production.
