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.

Rhodiola is a type of plant native to the Arctic regions of Europe and Asia. It is also known as "golden root" or "arctic root." The roots and rhizomes of Rhodiola are commonly used in dietary supplements for their purported effects as an 'adaptogen', which are used to improve physical and mental performance, reduce fatigue, and enhance the ability to cope with stress. Rhodiola is believed to work by increasing the production of certain chemicals in the brain (e.g., serotonin, dopamine, and norepinephrine) that are involved in mood and energy regulation. Rhodiola supplements are often standardized to a specific amount of their rosavin and salidroside content.
