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.

Glutathione is a naturally occurring compound that is composed of three amino acids: cysteine, glutamic acid, and glycine. It is found in nearly all cells in the body and plays a crucial role in many physiological processes, including as an antioxidant defense, detoxification, and immune function. Glutathione levels in the body can be decreased by a number of factors, such as aging, stress, poor diet, and exposure to toxins. Some people take glutathione supplements in the hopes of increasing their levels and potentially benefiting from its antioxidant properties. Glutathione supplements are available in various forms, including oral supplements, intravenous (IV) injections, and nebulized (inhaled) forms. Oral glutathione supplements are often in a liposomal form to improve absorption.

N-acetyl cysteine (NAC) is derived from the amino acid cysteine. It is used as a prescription medication to treat acetaminophen overdose and to help thin mucus in people with certain respiratory conditions. It is also used as a dietary supplement. NAC has a number of potential health benefits. It is a source of the antioxidant enzyme glutathione, which is important for protecting cells from oxidative stress and supporting immune function. It also may have anti-inflammatory effects and studies show it may support healthy brain function. It is generally considered safe to take NAC supplements in recommended doses.

Alpha-lipoic acid (ALA) is a naturally occurring compound that is made by the body and is also found in some foods, such as spinach, broccoli, and potatoes. It plays a role in energy production in the body and acts as an antioxidant, helping to protect cells from damage caused by free radicals. ALA has been studied for its potential health benefits, including the treatment of certain types of nerve damage, diabetes, and liver disease.

Parsley is a herb that is native to the Mediterranean region and is widely cultivated for its leaves, which are used as a spice in cooking. In traditional medicine, parsley is believed to have a number of health benefits and is often used as a natural diuretic, increasing urine production. This property may make parsley useful in the treatment of certain conditions, such as bloating and water retention. It is also commonly used for gastrointestinal problems.

Glycine is an amino acid found naturally in the body and is also available as a dietary supplement. It is considered a non-essential amino acid, meaning that the body can produce it on its own. Glycine supplementation has been studied for its potential to help improve sleep quality as it is purported to help to promote relaxation and reduce muscle tension. Some studies have also suggested that it may help to improve symptoms of sleep disorders such as insomnia. Glycine has also been studied for its potential to help with the management of some types of chronic pain, such as osteoarthritis, and for improving cognitive function.

L-glutamine is the most abundant free amino acid in the body, produced primarily in skeletal muscle and then released into circulation. It serves vital roles in various tissues, including the immune system, gastrointestinal tract, kidneys, and liver, where it supports essential functions such as maintaining intestinal integrity, immune response, and amino acid balance. Although traditionally classified as a non-essential amino acid, during periods of severe stress, glutamine becomes conditionally essential due to the body's increased demand. It acts as a critical nitrogen and carbon transporter between organs, and while the intestinal mucosa can synthesize glutamine, this production is insufficient during times of significant physiological stress. Dietary supplements generally contain L-glutamine as it is the biologically active form of the amino acid.
