Zinc is a mineral that is essential for the proper functioning of the human body. It is involved in many important physiological processes, including immune system function, wound healing, taste, and smell. Zinc is found in a variety of foods, including meat, seafood, and whole grains, and it is also available as a dietary supplement. Zinc supplements may be used to treat or prevent zinc deficiency, which can occur due to certain medical conditions, such as gastrointestinal disorders, alcohol abuse, and certain medications. Zinc supplements may also be used for other purposes, such as to boost the immune system, improve acne, and reduce the severity and duration of colds. There are several different forms of zinc supplements available, including zinc gluconate, zinc acetate, and zinc sulfate. The most common form of zinc supplements is zinc gluconate, which is well absorbed and is less likely to cause stomach-related side effects than other forms of zinc.

Selenium is an essential trace element that plays a crucial role in various physiological functions in the human body. It is often included in dietary supplements due to its antioxidant properties and its contribution to maintaining a healthy immune system. Selenium is important for thyroid function and may also have a role in protecting against certain chronic diseases. However, it's essential to note that excessive selenium intake can be harmful, so it's crucial to adhere to recommended daily allowances and consult with a healthcare professional before taking selenium supplements.

Theanine, often referred to as L-theanine as that is the predominant isomer of theanine, is an amino acid commonly found in tea leaves, particularly in green tea. It is purported to increase levels of GABA, serotonin, and dopamine in the brain, which can help to reduce stress and anxiety. L-theanine may also promote a sense of calm and improve overall well-being. Some studies have also suggested that it may improve cognitive function, although more research is needed. Most reported drug interactions with theanine are due to its sedative effects.

Melatonin is a hormone that is produced naturally in the pineal gland. It is involved in several different bodily processes, such as the regulation of the body's sleep-wake cycle. Melatonin is available as a dietary supplement and is often used to help people with sleep disorders, such as insomnia, fall asleep more easily. There is some evidence to suggest that melatonin supplements may be helpful in reducing the time it takes to fall asleep and improving sleep quality, although the results of studies on this topic have been mixed. Studies show better support for some specific conditions, such as Delayed sleep phase syndrome (DSPS) and Non-24-hour sleep-wake disorder. Melatonin is generally considered to be safe when used in the short term, although it can cause side effects in some people, such as dizziness, headache, and nausea. While melatonin is a natural hormone, it is often synthesized for its use in dietary supplements.

It is believed to work by stimulating the immune system and helping the body to fight off infection. Some studies have suggested that echinacea may be effective at reducing the severity and duration of colds and other respiratory infections, but more research is needed to confirm its effectiveness.
