Nicotinamide, also known as niacinamide, is a form of vitamin B3 that plays a crucial role in various biochemical processes within the body. It is a water-soluble vitamin that is essential for the conversion of nutrients into energy, supporting cellular metabolism and DNA repair. Nicotinamide is often utilized in compounded formulations due to its diverse therapeutic properties, including anti-inflammatory and antioxidant effects.

In dermatology, nicotinamide is widely recognized for its ability to improve skin health by reducing inflammation, enhancing the skin barrier function, and decreasing hyperpigmentation. It is frequently used in topical formulations to manage conditions such as acne, rosacea, and photoaging. Additionally, nicotinamide has been studied for its potential benefits in reducing the risk of non-melanoma skin cancers.

Beyond dermatological applications, nicotinamide is also explored for its neuroprotective properties. Research suggests that it may support brain health by promoting neuronal survival and reducing oxidative stress. This makes it a compound of interest in the management of neurodegenerative diseases like Alzheimer's and Parkinson's.

Furthermore, nicotinamide is involved in the synthesis of nicotinamide adenine dinucleotide (NAD+), a coenzyme critical for cellular energy production and repair processes. This connection to NAD+ synthesis underscores its importance in maintaining overall cellular health and longevity.

When considering nicotinamide in compounded formulations, it is important to note its excellent safety profile and minimal side effects, making it suitable for a wide range of patients. Its versatility and efficacy in various therapeutic areas highlight its value as an active pharmaceutical ingredient in personalized medicine.
