Focus By Qualia Overview & Drug Interactions

Niacin, also known as vitamin B3, is a water-soluble vitamin found in a variety of foods, including meat, poultry, fish, and fortified grains. It plays a variety of roles in the body, including in the metabolism of carbohydrates, fats, and proteins. It is also necessary for the production of energy in the body and in the synthesis of different hormones. Niacin deficiency is rare in developed countries, however, supplementation has been shown to have several positive benefits. For example, it can reduce the risk of diabetic neuropathy (i.e., nerve pain) and has been shown effective for treating some types of high cholesterol (extended-release niacin is used as a prescription drug in the United States for this purpose). There is a multitude of niacin forms available as dietary supplements, including NADH, niacinamide, and nicotinamide riboside, all with different properties.

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.

Ginger is a spice native to Asia and part of the Zingiberaceae family. It has a pungent, spicy flavor and is often used to add flavor to dishes and drinks. Ginger has a long history of use in traditional medicine and is believed to have anti-inflammatory, antioxidant, and other medicinal properties. It is commonly used to treat nausea, motion sickness, and other digestive issues. Ginger is also sometimes used to relieve pain and reduce inflammation. Ginger supplements generally standardize several compounds found in the root, and are often labeled as containing a certain amount of 'ginger root extract'.

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.

Ginkgo (Ginkgo biloba) is a tree native to Asia and is known for its distinctive fan-shaped leaves. The extract of the ginkgo leaf is commonly used in traditional medicine and is one of the most popular dietary supplements consumed worldwide. Its most common use is to help improve memory and cognitive function.

American ginseng (Panax quinquefolius) is a type of plant that is native to the eastern United States. It is a member of the Araliaceae family and is closely related to Asian ginseng (Panax ginseng). American ginseng has a long history of use in traditional medicine and is believed to have a number of potential health benefits. American ginseng is often referred to as an "adaptogen," which means that it may help the body to adapt to stress and improve overall well-being. It is commonly used to improve energy and mental clarity, and it has been suggested that it may have potential benefits for immune function, heart health, and diabetes management. American ginseng dietary supplements are generally standardized to contain 0.052% to 15% total ginsenosides, a group of compounds found in the plant.
