Vitamin B12, also known as cobalamin, is a water-soluble vitamin crucial for several bodily functions. It plays a pivotal role in the formation of red blood cells, aiding in the prevention of anemia. Vitamin B12 is essential for maintaining a healthy nervous system and proper brain function, as it is involved in the synthesis of myelin, the protective sheath around nerve fibers. This vitamin is primarily found in animal-based foods such as meat, fish, dairy products, and eggs, making it important for vegetarians and vegans to consider supplementation. A deficiency in vitamin B12 can lead to neurological issues, fatigue, and cognitive impairment.

Calcium is a vital nutrient found in various foods such as dairy products, certain vegetables, and many fortified items. Over 99% of the body's calcium is stored in the bones and teeth, predominantly as hydroxyapatite. The remaining calcium circulates in the blood, extracellular fluid, muscles, and other tissues, where it is essential for processes like nerve signaling, muscle contraction, vascular activities, glandular secretion, and maintaining cell membrane and capillary permeability. It also plays critical roles in enzyme reactions, respiration, kidney function, and blood clotting, and is involved in neurotransmitter and hormone release, amino acid uptake, vitamin B12 absorption, and gastrin secretion. Calcium balance changes with age: it is positive during periods of growth, stable in adulthood, and tends to become negative in older age. Calcium loss occurs through feces, urine, sweat, and shedding skin cells. In women, reduced estrogen levels decrease calcium absorption and retention, increase bone turnover, and lead to lower bone mass. Calcium supplements come in various forms, including citrate and carbonate, which differ mainly in their calcium content and absorption rates. Calcium citrate is easily absorbed and can be taken without food, making it suitable for older adults or those with low stomach acid. In contrast, calcium carbonate, which contains a higher percentage of calcium, is best absorbed when taken with meals.

Magnesium is a mineral that is essential for the proper functioning of the body. It plays a role in many important physiological processes, including the contraction and relaxation of muscles, the transmission of nerve impulses, and the regulation of blood pressure. Magnesium is found in a variety of foods, including leafy green vegetables, nuts, and grains, and it is also available as a dietary supplement. There are several different forms of magnesium that are available as supplements, all of which can be used to prevent deficiency. Additionally, magnesium is purported to have several different health benefits, such as improving sleep, reducing muscle cramps, reducing anxiety, and preventing or treating migraines. Although magnesium is essential for health, magnesium-containing foods and supplements can interact with some prescription medications if used at the same time.

Hops are the female flowers (also known as cones) of the hop plant, Humulus lupulus, and a member of the Cannabaceae family. Hops are native to Europe and are widely cultivated in many parts of the world. Hops have a variety of applications, such as for food flavoring and brewing beer. Hops extract has been used in topical medicinal preparations and as a dietary supplement.

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.

Inositol is a type of carbohydrate (sugar alcohol) that is found in a variety of foods, including fruits, nuts, and grains. It is also known as vitamin B8 but is not considered 'essential' as it can be synthesized in the human body. Inositol is involved in a number of important physiological processes, including the metabolism of fats, the regulation of insulin, and the transmission of nerve impulses. Inositol is a popular dietary supplement and is believed to have a number of potential health benefits. It is thought to have a role in the treatment of certain mental health conditions, is believed to have a positive effect on cholesterol levels and may be helpful in the prevention or management of heart disease. In addition, inositol may have anti-inflammatory effects and may be helpful in the treatment of certain skin conditions.

5-HTP, or 5-hydroxytryptophan, is a naturally-occurring amino acid and a precursor to the neurotransmitter serotonin. It is used as a dietary supplement to improve mood and help with anxiety, sleep disorders, and other conditions. It is also sometimes used in combination with other medications to treat migraines and fibromyalgia. The 5-HTP found in supplements is most often obtained from the seeds of the tropical shrub Griffonia simplicifolia

Peppermint is a perennial herb that is native to Europe and Asia. It is a member of the mint family (Lamiaceae) and is known for its fragrant, minty aroma and distinctive, spear-shaped leaves. Peppermint is commonly used in cooking and aromatherapy, as well as in a variety of personal care products. It has a refreshing, cool, and slightly sweet flavor. In traditional medicine, peppermint is believed to have a number of health benefits. It is thought to have anti-inflammatory and pain-relieving effects, and it is sometimes used to treat a variety of conditions, including digestive problems, respiratory infections, and skin disorders. Peppermint is also commonly used as a natural treatment for colds and flu due to its expectorant properties. Some peppermint supplements are marketed specifically towards those suffering from IBS (irritable bowel syndrome) as evidence shows it can help reduce symptoms in some individuals.

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.

Licorice, also known as glycyrrhiza, is a plant native to parts of Europe, Asia, and the Mediterranean region. The root of the plant has been used for centuries in traditional medicine and is often consumed in the form of candy, tea, and supplements. Licorice has a number of purported health benefits, including the ability to soothe sore throats, reduce inflammation, and improve digestive problems. It may also have antiviral and antibacterial properties. Licorice naturally contains glycyrrhizin, or glycyrrhizic acid, which can have toxic effects if consumed in large amounts. However, licorice can be processed to remove glycyrrhizin, resulting in DGL (deglycyrrhizinated licorice). Many dietary supplements that contain deglycyrrhizinated licorice are often simply named 'DGL'.

Gamma-aminobutyric acid (GABA) is an inhibitory neurotransmitter that is involved in a variety of functions, including regulating brain activity and behavior, relaxation, and sleep. GABA is endogenously produced in the brain from the amino acid glutamate and is responsible for inhibiting the activity of nerve cells in the brain and central nervous system. GABA is a popular dietary supplement and is used to help reduce anxiety and improve sleep, but more research is needed to determine its safety and effectiveness.

Phosphatidylserine is a phospholipid that plays a crucial role in cell structure and function, particularly in the brain. It's a key component of cell membranes, aiding in cell signaling and maintaining cellular integrity. In the context of the brain, phosphatidylserine supports cognitive function, memory, and neurotransmitter regulation. Additionally, it's commonly used as a dietary supplement to potentially enhance cognitive performance and mitigate age-related cognitive decline.
