I've been using Polyphenol Dark Spot Diminisher by Gundry MD, and it's really made my skin look brighter and more even. The niacinamide in it has noticeably faded some dark spots from sun exposure, and my skin overall looks healthier. Plus, it feels good to know it's also giving me antioxidant protection.

Niacinamide is a great addition to many supplement routines. I have been using a complex supplement with Niacinamide from Nutraharmony for a month and saw a significant reduction in fatigue, and my skin looks and feels better.

Taking Nicotinamide (500mg) and Pyruvate (1500mg) for open angle glaucoma as supplements to my timolol and bimatoprost prescribed drops. Several studies indicate that it may be effective in delaying optic nerve damage.
