Oxytocin
Oxytocin (Oxt) is a peptide hormone and neuropeptide. Oxytocin is normally produced by the paraventricular nucleus of the hypothalamus and released by the posterior pituitary. It plays a role in social bonding, sexual reproduction, childbirth, and the period after childbirth. Oxytocin is released into the bloodstream as a hormone in response to stretching of the cervix and uterus during labor and with stimulation of the nipples from breastfeeding. This helps with birth, bonding with the baby, and milk production. Oxytocin was discovered by Henry Dale in 1906. Its molecular structure was determined in 1952. Oxytocin is also used as a medication to facilitate childbirth.
Inositol nicotinate
Inositol nicotinate, also called inositol hexanicotinate, is marketed in the United States as a "no-flush niacin" dietary supplement. Flushing, in physiology, essentially means that epidermal tissues have become reddened, such as when the skin is irritated from the histamine responses related to an allergic reaction, or from recent physical exercise, or even from anger or embarrassment. This form of niacin is supposed to reduce or prevent flushing by being broken down into the metabolites niacin (nicotinic acid) and inositol at a slow rate.
