Thorne Niacinamide (Vitamin B3) – Non-Flushing Support for Sleep, Joints & Skin Thorne Niacinamide provides a high-quality, non-flushing form of vitamin B3 designed to support neurological calm, joint health, skin integrity, and cellular protection.* Also known as nicotinamide, niacinamide delivers the benefits of vitamin B3 without the uncomfortable flushing associated with niacin. Niacinamide plays a critical role in cellular energy metabolism and has been shown to support restful sleep and relaxation by gently stimulating neurotransmitter receptors in the brain, producing a calming, sedative-like effect—without binding directly to receptor sites.* This makes it an excellent option for individuals seeking nervous system support without drowsiness or dependency. In addition to neurological benefits, niacinamide acts as a powerful antioxidant, helping inhibit free radical formation and protect cells from oxidative stress.* Research also indicates niacinamide may help protect joint cartilage cells, especially when used at higher amounts, making it valuable for individuals concerned with joint comfort and long-term mobility.* Niacinamide has also been studied for its role in supporting pancreatic beta-cell regeneration, contributing to healthy metabolic function.* In dermatology, niacinamide is widely used to support healthy skin barrier function, making it beneficial for a variety of skin-related concerns.* Unlike some vitamin B3 sources, Thorne Niacinamide is not derived from yeast, making it suitable for individuals with yeast sensitivities or dietary restrictions.
