5-HTP (short for 5-hydroxytryptophan) is a substance made by the human
body from the amino acid tryptophan. 5-HTP also can be extracted from
the seeds of the Griffonia simplicifolia plant. Whether it’s
produced by the body itself or consumed in the form of a dietary
supplement, the body converts 5-HTP to the neurotransmitter serotonin, a
chemical that serves many functions related to mood, sleep, appetite,
and pain sensation. 

Ashwagandha is a plant used in traditional Ayurvedic and Unani medicine. It is commonly promoted for sleep, stress, and anxiety as well as cognitive function. Ashwagandha is also known as Withania somnifera, Indian ginseng, and winter cherry.

Vitamin B12 is a water-soluble vitamin that is naturally present in some
foods, added to others, and available as a dietary supplement and a
prescription medication. Because vitamin B12 contains the mineral
cobalt, compounds with vitamin B12 activity are collectively called
cobalamins [1].
Methylcobalamin and 5-deoxyadenosylcobalamin are the metabolically
active forms of vitamin B12. However, two others forms, hydroxycobalamin
and cyanocobalamin, become biologically active after they are converted
to methylcobalamin or 5-deoxyadenosylcobalamin [1-3].

Magnesium is a nutrient that the body needs to stay healthy. Magnesium is important for many processes in the body, including regulating muscle and nerve function, blood sugar levels, and blood pressure and making protein, bone, and DNA.
