What's the best form of b3 to take for acne?
Niacin (B3 as niacinamide)
Niacin (from inositol hexanicotinate)
Or something else? Both of these are non-flush.
Don't let anybody tell you, "You can't" just because they can't.
Niacinamide is the form most use for acne, you can take it orally but you would probably have better results applying it topically at 5%.
