When
it comes to stress, hypothalamus-pituitary-adrenal axis (HPA) is responsible for
stress response. Hypothalamus releases corticotropin-releasing hormone (CRH)
which binds to its receptors on the anterior pituitary gland. As a result, adrenocorticotropic hormone (ACTH) is released and it stimulates the release of
cortisol from the adrenal gland. At a certain levels of cortisol, this steroid
hormone exerts negative feedback to the hypothalamic release of CRH.
Answer:
True.

The right answer is: vitamin C and choline
Choline (vitamin B4) is the precursor on the one hand acetylcholine (important neurotransmitter and neuromodulator) and on the other hand, the cascade initiated by betaine (intermediate in the biological methylation and precursor of membrane lipids). In this, it is considered, by extension, as an integral part of the family of B vitamins,
Vitamin C protects against cellular aging, is essential for the immune defenses and increases the assimilation of iron of plant origin. It also contributes to the formation of collagen. Its deficiency leads to a disease called scurvy (hence the ascorbic acid name of vitamin C).
