Niacinamide supplements with the fewest additives
Niacinamide (also known as nicotinamide or nicotinic acid) is a vitamin B3 supplement that may help fight acne, osteoarthritis, and Alzheimer's disease. However, most niacinamide supplements contain more than just niacinamide.
For example, silica or silicon dioxide are often added to prevent caking, magnesium stearate or stearic acid for easier manufacturing, and hypromellose (hydroxypropyl methylcellulose) as an emulsifier or thickener.
I try to avoid these additives because they may have questionable health effects. If you want to do the same, my recommendations for the purest niacinamide supplements are:
Recommended as purest niacinamide capsule:
- silica-free / silicon-dioxide-free
- stearic acid-free / magnesium stearate-free
- hypromellose-free / hydroxypropyl methylcellulose-free
Niacin (as niacinamide), gelatin (capsule).
Also available as a hydroxypropyl methylcellulose vegetarian capsule.
