Vitamin E is a fat-soluble vitamin found naturally in a variety of foods, including vegetable oils, nuts, seeds, and leafy green vegetables. Vitamin E is also available as a dietary supplement and is often added to skincare products. Vitamin E has many roles in the body, including protecting cells from oxidative stress and supporting immune function.

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.

Chromium is a trace mineral that is found in small amounts in the human body. It is believed to play a role in the metabolism of carbohydrates, fats, and proteins. It is used as a dietary supplement for its purported ability to help with weight loss and blood sugar control. There is some evidence to suggest that chromium supplements may help to improve blood sugar control in people with type 2 diabetes, although the results of studies on this topic have been mixed. Some studies have found that chromium supplements can improve insulin sensitivity and reduce blood sugar levels in those with poorly controlled diabetes, while others have found no significant effects.

Bilberry is a small, perennial shrub that belongs to the Ericaceae family and is native to Europe, the northern United States, and Canada. It is known for its small, dark purple berries, which are similar in appearance to blueberries. The name bilberry is derived from the Danish word 'bollebar', meaning "dark berry". Bilberry is high in antioxidants, including flavonoids, and are a good source of vitamins and minerals, including vitamin C, vitamin E, and manganese. Bilberry has a long history of use in traditional medicine and is claimed to have a number of potential health benefits, including improving vision, reducing inflammation, and treating diarrhea.

Quercetin is a type of flavonoid, which is a class of compounds found in a wide variety of plants and foods. It is purported to have a number of health benefits such as anti-inflammatory, antioxidant, and immune-boosting effects. Studies suggest it may also help to reduce the risk of certain chronic diseases, such as heart disease. In addition, quercetin may have anti-allergic properties and may be helpful in the treatment of allergies and asthma. It is a popular dietary supplement worldwide and is often included in products that contain antioxidants or various vitamins/minerals. Its wide range of potential health benefits mean that it could potentiate the effects of other drugs (e.g., anti-hypertensives), which is why there are an abundant number of potential interactions listed for quercetin.

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.

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.
